Metabolic syndrome and obesity among marginalised school-going adolescents in Karachi, Pakistan: a cross-sectional study

Background

Metabolic syndrome (MetS) is a cluster of cardiometabolic risk factors which increase the likelihood of developing type 2 diabetes and cardiovascular disease. This study aimed to determine the prevalence of MetS among adolescents living in slums aged 11-18 years in Karachi, Pakistan.

Methods

Data were collected from 689 adolescents attending five schools in two slum areas of Karachi, Korangi and Baldia, from February 2023 to March 2023. Measurements of weight, height, waist circumference, and blood pressure were obtained from the study participants. Blood samples were collected to assess fasting plasma glucose, High density lipoprotein HDL-cholesterol, and triglyceride levels as per National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III). The prevalence of MetS was estimated using five diagnostic criteria, i.e., International Diabetes Federation (IDF-2007), World Health Organization, NCEP-ATP III, de Ferranti et al., and Cruz and Goran.

Findings

The study revealed an overall prevalence of MetS among the adolescents in the two slum areas as 16.7%. A higher prevalence of MetS was observed among females (9.1%) and those with lower body mass index BMI (13.6%). The diagnostic criteria proposed by Cruz and Goran were found to be the most sensitive, with a MetS diagnosis rate of 22.93%. The study also identified several significant risk factors associated with MetS, including sedentary lifestyle (7.7%), lack of physical activity (7.5%), increased screen time (1.5%), lower fruit consumption (6.1%), and underweight (7.7%). Among slum-dwelling adolescents, low levels of HDL-cholesterol (33.96 ± 5.21), high triglyceride levels (161.45 ± 63.09), and elevated fasting plasma glucose levels (112.59 ± 28.92) were prevalent components of MetS.

Interpretation

This study provides compelling evidence of a high prevalence of MetS among marginalised school-going adolescents in Karachi, Pakistan. The findings underscore the importance of early identification of adolescents at risk of developing MetS (especially those living in slum areas) and the implementation of effective preventive strategies to mitigate the risk of type 2 diabetes and cardiovascular disease in later life.

Using formative research to inform a mental health intervention for adolescents living in Indian slums: the ARTEMIS study

BACKGROUND

Adolescents are vulnerable to stressors because of the rapid physical and mental changes that they go through during this life period. Young people residing in slum communities experience additional stressors due to living conditions, financial stress, and limited access to healthcare and social support services. The Adolescents' Resilience and Treatment nEeds for Mental Health in Indian Slums (ARTEMIS) study, is testing an intervention intended to improve mental health outcomes for adolescents living in urban slums in India combining an anti-stigma campaign with a digital health intervention to identify and manage depression, self-harm/suicide risk or other significant emotional complaints.

METHODS

In the formative phase, we developed tools and processes for the ARTEMIS intervention. The two intervention components (anti-stigma and digital health) were implemented in purposively selected slums from the two study sites of New Delhi and Vijayawada. A mixed methods formative evaluation was undertaken to improve the understanding of site-specific context, assess feasibility and acceptability of the two components and identify required improvements to be made in the intervention. In-depth interviews and focus groups with key stakeholders (adolescents, parents, community health workers, doctors, and peer leaders), along with quantitative data from the digital health platform, were analysed.

RESULTS

The anti-stigma campaign methods and materials were found to be acceptable and received overall positive feedback from adolescents. A total of 2752 adolescents were screened using the PHQ9 embedded into a digital application, 133 (4.8%) of whom were identified as at high-risk of depression and/or suicide. 57% (n = 75) of those at high risk were diagnosed and treated by primary health care (PHC) doctors, who were guided by an electronic decision support tool based on WHO's mhGAP algorithm, built into the digital health application.

CONCLUSION

The formative evaluation of the intervention strategy led to enhanced understanding of the context, acceptability, and feasibility of the intervention. Feedback from stakeholders helped to identify key areas for improvement in the intervention; strategies to improve implementation included engaging with parents, organising health camps in the sites and formation of peer groups.

The trial has been registered in the Clinical Trial Registry India, which is included in the WHO list of Registries, Reference number: CTRI/2022/02/040307. Registered 18 February 2022.

Prevalence of HIV in slums area: a systematic review and meta-analysis

BACKGROUND

Human Immunodeficiency Virus (HIV) remains a significant global health burden, particularly affecting vulnerable populations residing in slum areas which is characterized by overcrowding, poverty, and limited access to healthcare services, create an environment conducive to the transmission and spread of HIV. Despite the recognition of this issue, there is a lack of comprehensive understanding regarding the prevalence of HIV in slums. The aim of this study was to systematically synthesize the existing global evidence on HIV prevalence in slum populations.

METHODS

A rigorous systematic literature review was conducted by searching multiple electronic databases, including Medline via PubMed, Scopus, Embase, Web of Sciences, and Directory of Open Access Journals (DOAJ), covering the period from January 1, 1990, to March 31, 2023. The quality and risk of bias for each included study were assessed using the Newcastle-Ottawa Scale. The pooled prevalence with its corresponding 95% confidence interval (CI) was calculated using a random-effects model with the Freeman-Tukey double arcsine transformation. The degree of heterogeneity among the studies was evaluated using the I2 test. Publication bias was also assessed using Egger's test. Additionally, subgroup analysis was performed to explore potential factors contributing to the observed heterogeneity.

RESULTS

A systematic examination of the relevant literature resulted in the inclusion of a total of 22 studies for the purpose of this meta-analysis. These studies collectively assessed a sizable cohort consisting of 52,802 participants. Utilizing a random-effects model, an estimation of the overall prevalence of HIV in the slum area was determined to be 10% (95% CI: 7-13%). Further delineation through subgroup analysis based on the gender revealed a higher prevalence of HIV among women, standing at 13% (95% CI: 8-19%, 18 studies: I2 = 98%), as opposed to men, where the prevalence was found to be 8% (95% CI: 6-12%, 16 studies: I2 = 95%). A geographical breakdown of the included studies revealed that Africa exhibited the highest prevalence, with a figure of 11% (95% CI: 9-13%, 18 studies: I2 = 98%). Subsequently, studies conducted in the American continent reported a prevalence of 9% (95% CI: 7-11%, 2 studies: I2 = 57%). The Asian continent, on the other hand, displayed the lowest prevalence of 1% (95% CI: 0-3%, 2 studies: I2 = 94%). Notably, studies employing rapid tests indicated a prevalence of 13% (95% CI: 9-17%, 6 studies: I2 = 94%), while those relying on self-reported data reported a lower prevalence of 8% (95% CI: 5-11%, 6 studies: I2 = 99%). Moreover, studies utilizing ELISA reported a prevalence of 9% (95% CI: 6-12%, 10 studies: I2 = 96%). Finally, it was determined that studies conducted in upper-middle-income countries reported a higher prevalence of 20% (95% CI: 16-24%, 5 studies: I2 = 45%), whereas studies conducted in lower- and middle-income countries reported a prevalence of 8% (95% CI: 6-10%, 12 studies: I2 = 98%).

CONCLUSION

The current study elucidates the troublingly high prevalence of HIV infection within slums area. Also, this finding underscores the urgent necessity for targeted and tailored interventions specifically aimed at curtailing the spread of HIV within slums. Policymakers must take cognizance of these results and devote their efforts towards the implementation of effective strategies to mitigate gender disparities, address poverty alleviation, and empower the inhabitants of these marginalized areas.

Food insecurity and associated factors among households with under-5 children in slum communities in Ibadan, Nigeria

INTRODUCTION

Food insecurity is a leading cause of childhood morbidity and mortality. This study assessed the prevalence of household food insecurity and its associated factors among under-5 children in Ibadan, Nigeria.

METHODS

This was a cross-sectional household survey of 1,027 under-5 children and their caregivers in urban and rural slums in Ibadan. We used an electronic interviewer-administered, semi-structured questionnaire adapted from the Nigeria Demographic Health Survey and Household Food Insecurity Access Scale was used to report sociodemo-economic characteristics, food insecurity, and anthropometric measurement. The household food insecurity scale consisted of nine questions graded from 0 (Never) to 3 (Often) computed to determine the presence of food insecurity. Nutrition indices were computed, and the results were classified according to World Health Organization 2006 cut-off points. Chi-square tests were used to assess associations between food insecurity and the independent variables. Binary logistic regression analyses were conducted to identify the predictors of food insecurity (α = 0.05).

RESULTS

The mean ages of the caregivers and under-5 children were 31.7 ± 7.47 years and 34.49 ± 15.8 months respectively. Overall, 530 (51.7%) children were females, and 765 (74.5%) had normal weight for height. In all, 195 (19.0%) households had food insecurity, while 832 (81.0%) households had food security (Chi-square = 103.364, p = < 0.001). Under-5 children living in urban slums were seven times more likely to experience household food insecurity compared to those in rural slums (AOR = 6.859, 95%CI = 4.524-10.509, p = < 0.001).

DISCUSSION

Household food insecurity was more prevalent in urban slums. Strengthening of the school health program would help identify children with nutritional deficits, and improve the overall health status of children living in slum communities.

Types of health service utilization in Mumbai slums: a community-based survey

OBJECTIVE

Sociodemographic factors play a crucial role in shaping the health-seeking behaviors of individuals residing in slum areas, particularly in their choice of healthcare facilities. Recognizing the importance of strengthening the existing healthcare systems, this research project was undertaken with the primary objective of comprehending the health-seeking behaviors among residents of Mumbai's slum dwellings in India. To achieve this goal, a comprehensive cross-sectional community needs assessment was conducted spanning from October 2018 to January 2019.

RESULTS

432 respondents reported utilizing at least one health facility in the past year. They reported using private hospitals (172), public hospitals (208), Community Health clinics [23], or other healthcare services (29). To gain further insights into the factors influencing these choices, logistic regression analysis was conducted. The analysis revealed that being female was found to be negatively associated with the selection of a general practitioner as a preferred healthcare provider. On the other hand, higher levels of education and income were found to have a positive association with the preference for private hospitals. Conversely, these factors were negatively associated with the choice of government hospitals.

"For my safety and wellbeing, I always travel to seek health care in a distant facility"-the role of place and stigma in HIV testing decisions among GBMSM - BSGH 002

Gays, bisexuals, and all other men who have sex with men (GBMSM) are heavily impacted by HIV in Ghana compared to the general population. In addition to HIV and same-sex intercourse stigma, barriers such as reduced privacy, lower-income status and limited health care facilities (HCF) affect HIV testing decisions among GBMSM. We employed a phenomenological research design to understand the role of place and stigma in HIV testing among GBMSM in slums. GBMSM (n = 12) from slums in Accra and Kumasi, Ghana, were recruited and engaged in face-to-face interviews. We used a multiple reviewer summative content analysis to analyze and organize our key findings. The HIV testing options we identified include 1. Government HCF, 2. NGO and community outreach 3. Peer-educated services. Factors influencing GBMSM to test for HIV at HCF outside their areas included 1. The location of HCF 2. HIV and sexual stigma from slum areas 3. Positive HCW attitudes at distant HCF. 4. Negative Healthcare worker (HCW) attitudes towards GBMSM. These findings highlighted how stigma from slums and HCW influence HIV testing decisions and the need for place-based interventions to address stigma among HCW in slums to improve testing among GBMSM.

Psychometric properties of Indonesian slums dwellers' place attachment

Social scientists have long considered place attachment to be an important factor in promoting environmentally sustainable behaviours among individuals. Raymond and colleagues have developed a five-factor place attachment measure, comprising place dependence, nature dependence, place attachment, family bonding, and friendship bonding, that encompasses most of the differentiations made and that has been amply tested for validity and reliability. However, the bulk of these confirmatory studies have been conducted in Western societies, neglecting people in the Global South and particularly people living in unstable, environmentally fragile regions such as slum areas. This study aims to fill this omission by testing the psychometric qualities of the five-factor place attachment measure in Indonesian slums using a dataset collected by the Resilient Indonesian Slums Envisioned (RISE) project. The dataset consists of a random sample of 700 respondents, living in slum areas of the cities of Bima, Manado, and Pontianak. We split the dataset into two and run factor analyses in EFA (N = 325) and CFA (N = 375) modes. Most notably, our results suggest a four-factor scale, in which place and nature dependences are merged into a single dimension. This finding seems logical considering that those living in urban slums are likely to have their natural surroundings, such as a river and its banks, as part of their living space. Overall, our study extends the use of place attachment to disaster-prone slum contexts that are often overlooked and, thus, supports the line of research that promotes environmental sustainability among people especially vulnerable to ecological changes.

Are livelihoods of slum dwellers sustainable and secure in developing economies? Evidences from Lucknow, Uttar Pradesh in India

Objectives

We adopted the Sustainable Livelihood Security (SLS) approach to assess the living conditions of slum dwellers in Lucknow, Uttar Pradesh, India. Keeping the urban poor at the centre, we attempted to bring out the multidimensional nature of poverty and explored various aspects of the livelihood of slum dwellers.

Methods

We surveyed 900 households from both notified and non-notified slums of Lucknow city to construct the SLS index, keeping the social, economic, infrastructural, health, and micro-environmental aspects of slum dwellers in the background. We collected data based on the household approach of the UN and the neighbourhood approach of the Government of India and aggregated the weighted index values under various sub-components to construct a composite index.

Results

The results suggested that the index values were low for both types of slum dwellers in Lucknow city specifically in the economic, infrastructural, and micro-environmental aspects. The results also showed that 'non-notified slum dwellers' were much more deficient in all the dimensions compared to their 'notified' counterparts. The livelihood condition of the marginalized households (backward castes and minorities) was especially precarious and vulnerable.

Conclusion

The findings reveal the existence of a high level of informality of livelihood of the urban poor in terms of housing, employment, health, and other basic amenities, and demonstrate that their livelihood condition is characterized by a low assets base, and poor strategies to overcome exigencies and risks.

Recommendations

This paper recommends enactment of an urban employment guarantee act, conducting of sabhas (meetings) at the ward level on a regular basis to promote awareness, and notification of non-notified slums to notified slums on regular basis for the overall development of slum dwellers.

Comparing full immunisation status of children (0-23 months) between slums of Kampala City and the rural setting of Iganga District in Uganda: a cross-sectional study

BACKGROUND

Immunisation remains the most cost-effective public health intervention in preventing morbidity and mortality due to Vaccine-Preventable Diseases (VPDs). The study aims to compare the differences in immunisation coverage amongst children aged 0 to 23 months living in slums of Kampala city and Iganga as rural districts in Uganda.

METHODS

This study utilises data from a cross-sectional survey done in 2019 in the slums of Kampala City and the rural district of Iganga within the Health and Demographic Surveillance Site (HDSS). It included 1016 children aged 0-23 months and their parents. A logistic regression model was used to analyse the relationship between multiple independent variables and the binary dependent variables (fully immunised) using Stata statistical software. The measures of association were odds ratios reported with a corresponding 95% confidence interval.

RESULTS

Out of the 1016 participants, 544 participants live in the rural area and 472 participants in the slums. Slums had 48.9% (n = 231) of fully immunised children whilst rural areas had 43.20% (n = 235). The multivariate analysis showed that children living in slums are more likely to be fully immunised as compared to their counterparts in rural areas (Odds ratio:1.456; p = 0.033; CI:1.030-2.058). Immunisation coverage for BCG (98.9%), Polio 0 (88.2%), Penta1 (92.7%), and Pneumo1 (89.8%) were high in both settlements. However, the dropout rate for subsequent vaccines was high 17%, 20% and 41% for Penta, pneumococcal and rota vaccines respectively. There was poor uptake of the new vaccines with slums having 73.4% and 47.9% coverage for pneumococcal and rota vaccines respectively and rural areas had 72.1% and 7.5% for pneumococcal and rota vaccines respectively.

CONCLUSION

The low full immunisation status in this study was attributed to the child's residence and the occupation of the parents. Lack of education and poor access to messages on immunisation (inadequate access to mass media) are other contributing factors. Educational messages on the importance of immunisation targeting these underserved populations will improve full immunisation coverage.

Identifying, Measuring, and Ranking Social Determinants of Health for Health Promotion Interventions Targeting Informal Settlement Residents

OBJECTIVES

Considering the importance of social determinants of health (SDHs) in promoting the health of residents of informal settlements and their diversity, abundance, and breadth, this study aimed to identify, measure, and rank SDHs for health promotion interventions targeting informal settlement residents in a metropolitan area in Iran.

METHODS

Using a hybrid method, this study was conducted in 3 phases from 2019 to 2020. SDHs were identified by reviewing studies and using the Delphi method. To examine the SDHs among informal settlement residents, a cross-sectional analysis was conducted using researcher-made questionnaires. Multilayer perceptron analysis using an artificial neural network was used to rank the SDHs by priority.

RESULTS

Of the 96 determinants identified in the first phase of the study, 43 were examined, and 15 were identified as high-priority SDHs for use in health-promotion interventions for informal settlement residents in the study area. They included individual health literacy, nutrition, occupational factors, housing-related factors, and access to public resources.

CONCLUSIONS

Since identifying and addressing SDHs could improve health justice and mitigate the poor health status of settlement residents, ranking these determinants by priority using artificial intelligence will enable policymakers to improve the health of settlement residents through interventions targeting the most important SDHs.

Ebola and slum dwellers: Community engagement and epidemic response strategies in urban Sierra Leone

The Ebola epidemic in West Africa (2013-2016) was a learning process for all - the population, health experts and practitioners, as well as government structures. Learning occurred in all stages of the response, from the initial lack of clarity and denial of Ebola's existence that contributed to public confusion; to the eventual acceptance of the existence of the Ebola threat whereupon fear and stigmatization reigned; to the later stages in which community engagement and ownership of the response arose. In this paper we describe how two urban poor communities in informal settlements in the Western Area of Sierra Leone responded to Ebola Virus Disease and how they deployed efficient strategies like the development and implementation of by-laws for monitoring and surveillance, thus helping to curb the epidemic. For future public health emergencies, we recommend that community engagement be pursued earlier and that efforts are made to ensure two-way knowledge exchange between responders and community stakeholders.

Barriers to health care utilization among patients with type 2 diabetes living in slums: a qualitative study from providers' perspective

BACKGROUND

Due to slum dwellers' deprivation, they are more likely to develop Type 2 Diabetes (T2D) and its complications. Type 2 Diabetes is a long-life disease that requires continuous health care utilization. One of the negative outcomes of slum-dwelling is health care underutilization. Therefore, this study aimed to understand barriers to health care utilization among those with T2D living in Tabriz slums, Iran, from the perspective of healthcare providers, in 2022.

METHODS

A phenomenological approach was used in this study. Purposive sampling for conducting in-depth interviews was used to select 23 providers consisting of general practitioners, midwives, nutritionists, and public health experts. We conducted a content analysis using the 7 stages recommended by Colaizzi. We used four criteria recommended by Lincoln and Guba for ensuring the research's trustworthiness.

RESULTS

Three main themes and 8 categories were developed. Three main themes are 1) health care provision system barriers, including four categories: lack of motivation, non-availability of facilities and doctors, poor relationship between patients and providers, and disruption in the process 2) coverage problems, including two categories: insurance inefficiency, and limited access, and 3) contextual barriers, including two categories: environmental problems, and socioeconomic barriers.

CONCLUSIONS

Recommendations are presented in three levels to improve implementation. The health care system needs to modify the payment methods, Patients-providers relationship improvement, and increase the number of providers. Insurance organizations should consider sufficient coverage of costs for slum-dwellers with T2D and expand the benefits package for them. Government should consider infrastructure upgrading in slums to eliminate barriers related to slum-dwelling. Overall, health care utilization promotion needs intersection cooperation.

The connection between slums and COVID-19 cases in Jakarta, Indonesia: A case study of Kapuk Urban Village

COVID-19 has spread world-wide, and with multiple health, social, and economic ramifications. These present a formidable challenge for those belonging to vulnerable communities, such as those living in slums. There is now a growing literature urging attention to this challenge. However, few studies have examined the actual lived realities within these areas using direct, observational research, notwithstanding commentary elsewhere that such close attention is necessary to ensure effective action. This study took this approach in relation to a particular case-study, Kapuk Urban Village, in Jakarta, Indonesia. Drawing on an existing schema involving three spatial scales of slum areas (environs, settlement, and object), the research confirms how different built and socio-economic features can exacerbate vulnerability, and COVID-19 transmission. We also add to the body of knowledge by contributing a dimension of 'ground-level' research engagement. We conclude by discussing related ideas around ensuring community resilience and effective policy implementation, and recommend an "urban acupuncture" approach to encourage government regulations and actions better tailored to such communities.

Climate change and health risks in Mukuru informal settlement in Nairobi, Kenya - knowledge, attitudes and practices among residents

BACKGROUND

Residents of informal settlements in Sub-Sahara Africa (SSA) are vulnerable to the health impacts of climate change. Little is known about the knowledge, attitudes and practices (KAP) of inhabitants of informal settlements in SSA regarding climate change and its health impacts. The aim of this study was to investigate how inhabitants of an informal settlement in SSA experience climate change and its health impacts and assess related knowledge, attitudes and practices. The study was conducted in Mukuru informal settlement in Nairobi City County, Kenya.

METHODS

A cross-sectional study was conducted in September 2021 using a structured, semi-closed KAP questionnaire. Inclusion criteria were ≥ 18 years of age and living in one of the three main sections in Mukuru: Kwa Njenga, Kwa Reuben or Viwandani. By spinning a pen at the geographic centre of each section, a random direction was selected. Then, in every second household one individual was interviewed, creating a representative mix of ages and genders of the local community. To assess participant characteristics associated with climate change knowledge multivariable logistic regression was used. Thematic content analysis was performed for qualitative responses.

RESULTS

Out of 402 study participants, 76.4% (n = 307) had heard of climate change before the interview, 90.8% (n = 365) reported that climate change was affecting their community, and 92.6% (n = 372) were concerned with the health-related impact of climate change. Having lived in Mukuru for more than 10 years and living in a dwelling close to the riverside were factors significantly associated with having heard of climate change before (aOR 3.1, 95%CI 1.7 - 5.8 and aOR 2.6, 95%CI 1.1 - 6.1, respectively) and experiencing a climate change related impact on the community (aOR 10.7, 95%CI 4.0 - 28.4 and aOR 7.7; 95%CI 1.7 - 34.0, respectively). Chronic respiratory conditions, vector-borne diseases, including infectious diarrhoea, malnutrition and cardiovascular diseases were identified by respondents as climate related health risks.

CONCLUSIONS

Most respondents were knowledgeable about climate change and were experiencing its (health-related) impact on their community. This study provides insights which may prove useful for policy makers, intervention planners and researchers to work on locally adapted mitigation and adaption strategies.

Food Vendors and the Obesogenic Food Environment of an Informal Settlement in Nairobi, Kenya: a Descriptive and Spatial Analysis

Food environments of urban informal settlements are likely drivers of dietary intake among residents of such settlements. Yet, few attempts have been made to describe them. The objective of this study was to characterize the food environment of a densely-populated informal settlement in Nairobi, Kenya according to the obesogenic properties and spatial distribution of its food vendors. In July-August 2019, we identified food vendors in the settlement and classified them into obesogenic risk categories based on the types of food that they sold. We calculated descriptive statistics and assessed clustering according to obesogenic risk using Ripley's K function. Foods most commonly sold among the 456 vendors in the analytic sample were sweets/confectionary (29% of vendors), raw vegetables (28%), fried starches (23%), and fruits (21%). Forty-four percent of vendors were classified as low-risk, protective; 34% as high-risk, non-protective; 16% as low-risk, non-protective; and 6% as high-risk, protective. The mean distance (95% confidence interval) to the nearest vendor of the same obesogenic risk category was 26 m (21, 31) for vendors in the low-risk, protective group; 29 m (25, 33) in the high-risk, non-protective group; 114 m (88, 139) in the high-risk, protective group; and 43 m (30, 56) in the low-risk, non-protective group. Clustering was significant for all obesogenic risk groups except for the high-risk, protective. Our findings indicate a duality of obesogenic and anti-obesogenic foods in this environment. Clustering of obesogenic foods highlights the need for local officials to take action to increase access to health-promoting foods throughout informal settlements.

Food price volatility and socio-economic inequalities in poor food consumption status during coronavirus disease-2019 lockdown among slum and non-slum households in urban Nansana municipality, Uganda

BACKGROUND

This study assessed staple food price volatility, household food consumption scores (FCS), poor household food consumption status and its association with socio-economic inequalities during enforcing and partial lifting of coronavirus disease-2019 (COVID-19) lockdown restrictions in slum and non-slum households (HHs) of Nansana municipality, Uganda.

METHODS

Repeated cross-sectional surveys were conducted during enforcing and partial lifting of COVID-19 lockdown restrictions. A total of 205 slum and 200 non-slum HHs were selected for the study. Telephone based interviews with HH heads were used to collect data on socio-economic factors. Data for FCS was collected using the World Food Programme FCS method. Prices for staple foods were collected by face-to-face interviews with food vendors from the local market. Mean staple food price differences before COVID-19 lockdown, during enforcing, and partial lifting of lockdown was tested by Analysis of variance with repeated measures. Multivariate logistic regression analysis was used to assess the association between socio-economic variables and poor food consumption status. A statistical test was considered significant at p < 0.05.

RESULTS

Mean staple food prices were significantly higher during enforcing COVID-19 total lockdown restrictions compared to either 1 week before lockdown or partial lifting of lockdown (p < 0.05). Mean FCS for staple cereals and legumes were significantly higher in slum HHs during COVID-19 lockdown compared to when the lockdown was partially lifted (p < 0.05). In slum HHs, the prevalence of poor food consumption status was significantly higher during partial lifting (55.1%) compared to total lockdown of COVID-19 (15.1%), p < 0.05. Among slum HHs during lockdown restrictions, food aid distribution was negatively associated with poor food consumption status (AOR: 0.4, 95% CI: 0.1-0.6), whilst being a daily wage earner was positively associated with poor food consumption status (AOR: 0.5, 95% CI: 0.1-0.6). During partial lifting of COVID-19 lockdown in slum HHs, poor food consumption status was positively associated with female headed HHs (AOR: 1.2, 95%CI: 1.1-1.6), daily wage earners (AOR: 3.2, 95% CI: 2.6-3.8), unemployment (AOR: 1.9, 95% CI: 1.5-2.1) and tenants (AOR: 2.4, 95% CI: 1.8-3.5). Female headed HHs, daily wage earners and tenants were positively associated with poor food consumption status either during enforcing or partial lifting of COVID-19 lockdown restrictions in non-slum HHs.

CONCLUSION

Staple food prices increased during enforcing either the COVID-19 lockdown or partial lifting of the lockdown compared to before the lockdown. During the lockdown, food consumption improved in slum HHs that received food aid compared to those slum HHs that did not receive it. Household heads who were females, daily wage earners, unemployed, and tenants were at risk of poor food consumption status either in slum or non-slum, and therefore needed some form of food assistance either during enforcing or partial lifting of the lockdown.

Social vulnerability, exposure to environmental risk factors, and accessibility of healthcare services: Evidence from 2,000+ informal settlements in Argentina

Globally, the question of how to improve the living standards of the inhabitants of informal settlements is a key political concern. These neighborhoods are characterized by economic vulnerability, social marginalization, and inaccessibility of basic services. The aim of this study is to provide evidence about the environmental risk factors faced by these populations in Argentina, and to identify whether their greater exposure to risk factors is associated with greater accessibility of healthcare services. We analyzed an original database that provides information about basic characteristics of the neighborhood, environmental risk factors (proximity to garbage dumps, industrial waste, and high-voltage towers), and accessibility of basic healthcare services on over 2000 informal settlements in Argentina. We calculated descriptive statistics and developed multivariate econometric models to estimate the probability of accessibility of healthcare services. On average, 31% of informal settlements were close to a garbage dump, 19% were close to a high-voltage tower, and 10% were close to industrial waste. In addition, 39% of these neighborhoods do not have a healthcare center nearby, 65% do not have an accessible hospital, and 39% are not consistently served by ambulances in the event of an emergency. The econometric estimates suggest that the accessibility of hospital healthcare service and to an ambulance service is positively associated with the age of the neighborhood, and whether the neighborhood is a slum, but there is no evidence of association with the exposure to environmental risk factors. In short, the populations living in informal settlements in Argentina are exposed to harmful environmental risk factors. Access to basic healthcare services is limited and does not reflect the elevated exposure to environmental risks. Health, environmental, and economic dimensions should be considered when designing and implementing public policies for vulnerable populations.

An intervention to reduce stigma and improve management of depression, risk of suicide/self-harm and other significant emotional or medically unexplained complaints among adolescents living in urban slums: protocol for the ARTEMIS project

BACKGROUND

There are around 250 million adolescents in India. Adolescents are vulnerable to common mental disorders with depression and self-harm accounting for a major share of the burden of death and disability in this age group. Around 20% of children and adolescents are diagnosed with/ or live with a disabling mental illness. A national survey has found that suicide is the third leading cause of death among adolescents in India. The authors hypothesise that an intervention involving an anti-stigma campaign co-created by adolescents themselves, and a mobile technology-based electronic decision support system will help reduce stigma, depression, and suicide risk and improve mental health for high-risk adolescents living in urban slums in India.

METHODS

The intervention will be implemented as a cluster randomised control trial in 30 slum clusters in each of the cities of Vijayawada and New Delhi in India. Adolescents aged 10 to 19 years will be screened for depression and suicide ideation using the Patient Health Questionnaire (PHQ-9). Two evaluation cohorts will be derived-a high-risk cohort with an elevated PHQ-9 score ≥ 10 and/or a positive response (score ≥ 2) to the suicide risk question on the PHQ-9, and a non-high-risk cohort comprising an equal number of adolescents not at elevated risk based on these scores.

DISCUSSION

The key elements that ARTEMIS will focus on are increasing awareness among adolescents and the slum community on these mental health conditions as well as strengthening the skills of existing primary healthcare workers and promoting task sharing. The findings from this study will provide evidence to governments about strategies with potential for addressing the gaps in providing care for adolescents living in urban slums and experiencing depression, other significant emotional or medically unexplained complaints or increased suicide risk/self-harm and should have relevance not only for India but also for other low- and middle-income countries.

Slums and pandemics

How do slums shape the economic and health dynamics of pandemics? A difference-in-differences analysis using millions of mobile phones in Brazil shows that residents of overcrowded slums engaged in less social distancing after the outbreak of Covid-19. We develop and calibrate a choice-theoretic equilibrium model in which individuals are heterogeneous in income and some people live in high-density slums. Slum residents account for a disproportionately high number of infections and deaths and, without slums, deaths increase in non-slum neighborhoods. Policy analysis of reallocation of medical resources, lockdowns and cash transfers produce heterogeneous effects across groups. Policy simulations indicate that: reallocating medical resources cuts deaths and raises output and the welfare of both groups; mild lockdowns favor slum individuals by mitigating the demand for hospital beds, whereas strict confinements mostly delay the evolution of the pandemic; and cash transfers benefit slum residents to the detriment of others, highlighting important distributional effects.

Exposure to job-related violence among young female sex workers in urban slums of Southwest Nigeria

Background

In Nigeria, many young girls are engaged in commercial sex work as a means of livelihood and support of dependent relatives. Although studies have documented some of the violence related issues among commercial sex workers, the plight of adolescent and young sex workers particularly in urban slums may be different in context and depth.

Objective

This study explored the lived experiences of violence and health related harm among vulnerable young female sex workers in urban slums in Ibadan and Lagos, Southwest Nigeria. It also analyzed their coping strategies and survival mechanisms.

Design

The study is cross-sectional and applied an interpretive phenomenological approach to this qualitative study through in-depth interviews.

Participants

Young female sex workers ages (15–24 years) who reported having experienced violence were recruited for the study. Twelve participants completed the interviews out the 20 initially contacted.

Data collection and analysis

Primary data were collected using in-depth interviews (IDIs). Data were transcribed using a phenomenological framework analysis. Participants’ reports based on life experiences were identified: lived experience “daily brothel life experience”; sources of violence such as law enforcement agents’ intermittent raids; violence experience with clients who often demanded sexual acts beyond the agreed scope; and coping strategies employed to mitigate the challenges.

Settings

The study was conducted in brothels of two selected slum areas in Ibadan and Lagos, Southwest Nigeria.

Results

The results showed that the major motivation for engaging in commercial sex work was for economic reasons. However, there are inherent risks involved particularly for the vulnerable young people. Stigmatization from the community, clients’ uncontrolled-aggressive behavior and harassment from law enforcement agents are some of the frequent violence experiences reported. Self-help coping strategies are usually employed to prevent or mitigate the challenges.

Conclusion

The plight of this young people required policy and program attention towards alternative economic empowerment to rehabilitate those willing to leave the profession. Also the need to develop arm reduction interventions towards protection of young sex workers against violence.

Validation and minimally important difference of the Child-OIDP in a socioeconomically diverse sample of Indian adolescents

INTRODUCTION

While different measures have been validated and used to assess the oral health related quality of life (OHRQoL) of children and adolescents, no previous study has tested the psychometric performance of OHRQoL amongst the most marginalized adolescents, living in extremely deprived neighbourhoods like urban slums and resettlement areas in modern cities. Our study assessed the internal consistency reliability, construct validity and Minimally Important Difference (MID) of the Child-OIDP in a sample of adolescents aged 12-15 years reporting oral health problems that lived in three different types (including two extremely vulnerable) of neighbourhoods (urban slums, resettlement colonies, and middle and upper middle-class neighbourhoods) in the National Capital Territory of Delhi.

METHODS

We conducted data analysis on a cross-sectional study, comprising of 840 adolescents. The Child-OIDP was used as a measure of OHRQoL. Internal consistency reliability was tested using the standardized Cronbach's Alpha Coefficient. The Child-OIDP was also tested for content and construct validity (the latter through the median test), while a distribution-based approach was used to identify the MID.

RESULTS

The Indian Child-OIDP showed good internal consistency, as the Cronbach's alpha coefficient was 0.77. Inter-item correlation coefficients among the items ranged from 0.13 to 0.50, with the mean inter-item correlation being 0.30. The corrected item-total correlations ranged from 0.30 (social contact) to 0.54 (speaking). For construct validity, the Child-OIDP extent was significantly associated with three subjective oral and general health variables in the expected direction. The calculated effect sizes for these differences indicated that they were moderate (0.50-0.79). We also calculated the standard error of measurement (SEM) of Child-OIDP extent as 0.75.

CONCLUSION

This study demonstrated that the Indian Child-OIDP is a reliable and valid measure for the assessment of the oral health related quality of life among Indian adolescents especially from marginalised and socioeconomically vulnerable groups. This is an essential step towards assessing oral health and evaluating oral health promotion interventions in those populations and settings.

Predictors of postnatal depression in the slums Nairobi, Kenya: a cross-sectional study

BACKGROUND

Postnatal depression (PND) is a universal mental health problem that prevents mothers' optimal existence and mothering. Although research has shown high PND prevalence rates in Africa, including Kenya, little research has been conducted to determine the contributing factors, especially in low-resource communities.

OBJECTIVE

This study aimed to investigate the PND risk factors among mothers attending Lang'ata and Riruta Maternal and Child Health Clinics (MCH) in the slums, Nairobi.

METHODS

This study was cross-sectional. It is part of a large study that investigated the effectiveness of a brief psychoeducational intervention on PND. Postnatal mothers (567) of 6-10 weeks postanatal formed the study population. Depression rate was measured using the original 1961 Beck's Depression Inventory (BDI). In addition, a sociodemographic questionnaire (SDQ) was used to collect hypothesized risk variables. Multivariable logistic regression analysis was used to explore predictors of PND.

RESULTS

The overall prevalence of PND in the sample of women was 27.1%. Women aged 18-24 (β = 2.04 95% C.I.[0.02; 4.05], p = 0.047), dissatisfied with body image (β = 4.33 95% C.I.[2.26; 6.41], p < 0.001), had an unplanned pregnancy (β = 2.31 95% C.I.[0.81; 3.80], p = 0.003 and felt fatigued (β = - 1.85 95% C.I.[- 3.50; 0.20], p = 0.028) had higher odds of developing PND. Participants who had no stressful life events had significantly lower depression scores as compared to those who had stressful life events (β = - 1.71 95% C.I.[- 3.30; - 0.11], p = 0.036) when depression was treated as a continuous outcome. Sensitivity analysis showed that mothers who had secondary and tertiary level of education had 51 and 73% had lower likelihood of having depression as compared to those with a primary level of education (A.O.R = 0.49 95% C.I.[0.31-0.78], p = 0.002) and (A.O.R = 0.27 95% C.I.[0.09-0.75], p = 0.013) respectively.

CONCLUSION

This study reveals key predictors/risk factors for PND in low-income settings building upon the scanty data. Identifying risk factors for PND may help in devising focused preventive and treatment strategies.

Do Community-based Livelihood Interventions Affect Sexual and Reproductive Health and Rights of Young People in Slum Areas of Uganda: a Difference-in-difference with Kernel Propensity Score Matching Analysis

Slum dwellers across Africa have been targeted in interventions whose impacts remain unclear. We evaluated the impact of a livelihood intervention on the sexual and reproductive health and rights (SRHR) of young people in the slum areas of Kampala, Uganda. We carried out a repeated cross-sectional survey in 2014 and 2017 to examine the impact of community-based livelihood interventions on the SRHR of young people in the slum areas of Kampala, Uganda. Impacts were observed such as reduced sexual activity, reduction in aspects of gender-based violence attitudes and beliefs, increased access to and decision-making about contraceptive and family-planning services, increased availability and affordability of SRHR services, reduced need to seek further knowledge on SRHR, reduced barriers to HIV testing, and increased knowledge of health responsibilities. Unexpected results included: increased proportion of young people who had ever had sex, decreased mean age of sexual debut, unaffordability of contraceptives, and increased culturally shaped attitudes and social norms related to gender-based violence. We observed no impact on condom use, consensual sex and sexual assault, the number of sexual partners, knowledge about HIV/AIDS, stigma and discrimination against people living with HIV/AIDS, affordability of male and female condoms, and uptake of HIV testing services. Rights-based interventions are crucial to how we understand the SRHR of young people in complex sociocultural environments. While the livelihood interventions made significant impacts on the SRHR of young people, there are questions about how such interventions address deeply rooted sociocultural practices to maximise outcomes.

Sexual and reproductive health education and its association with ever use of contraception: a cross-sectional study among women in urban slums, Accra

Background

Sexual and reproductive health education among girls and women has several reproductive health benefits, including improved contraceptive knowledge, contraception use at first intercourse, increased chance of contraceptive use in a lifetime, and effective usage of contraceptives. It is however not clear whether women/girls in urban slums who have had sexual and reproductive health education would likely utilize contraception. This study sets out to test the hypothesis that Accra slum women who have had sex education have higher chances of ever using contraception.

Methods

A cross-sectional survey was conducted among reproductive aged women in two slums (i.e. Agbogbloshie and Old Fadama) in Accra, Ghana. A sample size of 691, made up of respondents who provided responses to the question on ever used contraception, sex education as well as those with complete information on all the other variables of interest was considered in this study. Binary logistic regression models were fitted to examine association between sexual and reproductive health education and ever use of contraception. Crude odds ratios (cOR) and adjusted odds ratios (aOR) at p-value less than 0.05 were used to assess the strength of the association between the outcome and independent variables.

Results

More than half (56.73%) of the women have never received sexual and reproductive health education. Most of the respondents (77.28%) had ever used contraceptives. Women who had no form of sexual and reproductive health education had lower odds of ever using contraception (OR = 0.641, 95% CI 0.443, 0.928) and this persisted after controlling for the effect of demographic factors (AOR = 0.652, 95% CI 0.436, 0.975] compared to those who have ever received any form of sex education. Non-married women as well as women who were exposed to media (newspapers/radio/television) were also more likely to use contraceptives in slums in Accra, Ghana.

Conclusion

The study revealed a relatively low prevalence of sex education among women in urban slums in Accra. However, sex education was found to increase the odds of ever use of contraception. These findings call for intensified sexual and reproductive health education among reproductive aged girls and women in urban slums in Accra using existing informal social networks and local media platforms.

Sexual and reproductive health education among girls and women has several reproductive health benefits, including improved contraceptive knowledge, contraception use at first intercourse, increased chance of contraceptive use in a lifetime, and effective usage of contraceptives. It is however not clear whether women/girls in urban slums who have had some form of sex education would likely utilize contraception more than those who have not. This study sets out to test the hypothesis that Accra slum women who have had sex education have higher chances of ever using contraception. A cross-sectional survey was conducted among reproductive aged women in two slums (i.e. Agbogbloshie and Old Fadama) in Accra, Ghana. A sample size of 691 girls/women aged 15–49 was considered. More than half (56.73%) of the women had never received some form of sex education. Most of the respondents (77.28%) had ever used contraceptives. Women who had no form of sex education had lower odds of ever using contraception and this persisted after controlling for the effect of demographic factors compared to those who have ever received any form of sex education. Non-married women as well as women who were exposed to media (newspapers/radio/television) were also more likely to use contraceptives in slums in Accra, Ghana. In sum, the study revealed that while prevalence of sex education was relatively low among urban slum women, sex education generally increased the chances of ever use of contraception. These findings call for more and targeted sexual and reproductive health education among reproductive aged girls and women in urban slums in Accra using existing informal social networks and local media platforms.

JUE insights: Does mobility explain why slums were hit harder by COVID-19 in Mumbai, India?

SARS-CoV-2 has had a greater burden, as measured by rate of infection, in poorer communities within cities. For example, 55% of Mumbai slums residents had antibodies to COVID-19, 3.2 times the seroprevalence in non-slum areas of the city according to a sero-survey done in July 2020. One explanation is that government suppression was less severe in poorer communities, either because the poor were more likely to be exempt or unable to comply. Another explanation is that effective suppression itself accelerated the epidemic in poor neighborhoods because households are more crowded and residents share toilet and water facilities. We show there is little evidence for the first hypothesis in the context of Mumbai. Using location data from smart phones, we find that slum residents had nominally but not significantly (economically or statistically) higher mobility than non-slums prior to the sero-survey. We also find little evidence that mobility in non-slums was lower than in slums during lockdown, a subset of the period before the survey.

Childhood vaccination timeliness following maternal migration to an informal urban settlement in Kenya

INTRODUCTION

Timely receipt of recommended vaccines is a proven strategy to reduce preventable under-five deaths. Kenya has experienced impressive declines in child mortality from 111 to 43 deaths per 1000 live births between 1980 and 2019. However, considerable inequities in timely vaccination remain, which unnecessarily increases risk for serious illness and death. Maternal migration is a potentially important driver of timeliness inequities, as the social and financial stressors of moving to a new community may require a woman to delay her child's immunizations. This analysis examined how maternal migration to informal urban settlements in Nairobi, Kenya influenced childhood vaccination timeliness.

METHODS

Data came from the Nairobi Urban Health and Demographic Surveillance System, 2002-2018. Migration exposures were migrant status (migrant, non-migrant), migrant origin (rural, urban), and migrant type (first-time, circular [previously resided in settlement]). Age at vaccine receipt (vaccination timeliness) was calculated for all basic vaccinations. Accelerated failure time models were used to investigate relationships between migration exposures and vaccination timeliness. Confounding was addressed using propensity score weighting.

RESULTS

Over one-third of the children of both migrants and non-migrants received at least one dose late or not at all. Unweighted models showed the children of migrants had shorter time to OPV1 and DPT1 vaccine receipt compared to the children of non-migrants. After accounting for confounding only differences in timeliness for DPT1 remained, with the children of migrants receiving DPT1 significantly earlier than the children of non-migrants. Timeliness was comparable among migrants with rural and urban origins and among first-time and circular migrants.

CONCLUSION

Although a substantial proportion of children in Nairobi's informal urban settlements do not receive timely vaccination, this analysis found limited evidence that maternal migration and migration characteristics were associated with delays for most doses. Future research should seek to elucidate potential drivers of low vaccination timeliness in Kenya.

The Impact of Preventive Interventions on Intimate Partner Violence among Pregnant Women Resident in Hamadan City Slum Areas Using the PEN-3 Model: Control Randomized Trial Study

BACKGROUND

Intimate partner violence is a severe life-threatening criminal and public health problem affecting the well-being of individuals, families, and society. Planning interventions to reduce the burden of this persistent and criminal violence should be relevant culturally and socially.

METHODS

In this randomized control trial, 150 pregnant women residing in slum areas of Hamadan were randomly assigned to two groups (intervention group: n=50 and control group: n=100). Interventional strategies included educating the victims based on local cultural norms, culturally sensitive individual and group counseling, and educating health care providers. Data were collected via face-to-face interviews at baseline and again at 3 months after the intervention. We used a paired t-test to evaluate the effect of the intervention by comparing changes in the outcomes measured.

RESULTS

There were no statistically significant differences between the two groups at baseline in terms of sociodemographic characteristics. Post-test scores of knowledge (7.50±2.65 vs. 5.14±3.51, P=0.001), communication skills (18.38±4.25 vs. 16.2±3.83, P=0.04), and family support and social expectation of obedience (15.79±4.45 vs. 13.40±4.57, P=0.005) of the victims were statistically significantly higher in the experimental group compared to the control group. Moreover, physical (0.74±2.28 vs. 1.20±2.60, P=0.06), psychological (2.80±4.10 vs. 4.52±5.43, P=0.06), and sexual (0.11±0.58 vs. 0.61±1.22, P=0.04) violence reduced in the experimental group compared to the control group.

CONCLUSION

Culturally relevant interventions can reduce intimate partner violence.

Demographic drivers of Norway rat populations from urban slums in Brazil

The Norway rat is a globally distributed pest, known for its resilience to eradication and control programs. Efficient population control, especially in urban settings, is dependent on knowledge of rat demography and population ecology. We analyzed the relationship between four demographic outcomes, estimated by live-trapping data, and fine-scale environmental features measured at the capture site. Wounds, a proxy for agonistic interactions, were associated with mature individuals. Areas with environmental features favorable to rats, such as open sewers and unpaved earth, were associated with more mature individuals with a better body condition index. The control measures (environmental stressors) are likely to be disrupting the social structure of rat colonies, increasing the frequency and distribution of agonistic interactions, which were common in both sexes and maturity states. The relationship between the favorable environmental conditions and the demographic markers analyzed indicate possible targets for infestation control through environmental manipulation, and could be incorporated into current pest management programs to achieve long-term success. Our study indicate that urban interventions focused on removal of potential resources for rats could be potential long-term solutions by reducing the carrying capacity of the environment.

Pharmacies in informal settlements: a retrospective, cross-sectional household and health facility survey in four countries

BACKGROUND

Slums or informal settlements characterize most large cities in LMIC. Previous evidence suggests pharmacies may be the most frequently used source of primary care in LMICs but that pharmacy services are of variable quality. However, evidence on pharmacy use and availability is very limited for slum populations.

METHODS

We conducted household, individual, and healthcare provider surveys and qualitative observations on pharmacies and pharmacy use in seven slum sites in four countries (Nigeria, Kenya, Pakistan, and Bangladesh). All pharmacies and up to 1200 households in each site were sampled. Adults and children were surveyed about their use of healthcare services and pharmacies were observed and their services, equipment, and stock documented.

RESULTS

We completed 7692 household and 7451 individual adults, 2633 individual child surveys, and 157 surveys of pharmacies located within the seven sites. Visit rates to pharmacies and drug sellers varied from 0.1 (Nigeria) to 3.0 (Bangladesh) visits per person-year, almost all of which were for new conditions. We found highly variable conditions in what constituted a "pharmacy" across the sites and most pharmacies did not employ a qualified pharmacist. Analgesics and antibiotics were widely available but other categories of medications, particularly those for chronic illness were often not available anywhere. The majority of pharmacies lacked basic equipment such as a thermometer and weighing scales.

CONCLUSIONS

Pharmacies are locally and widely available to residents of slums. However, the conditions of the facilities and availability of medicines were poor and prices relatively high. Pharmacies may represent a large untapped resource to improving access to primary care for the urban poor.

Unveiling and addressing implementation barriers to routine immunization in the peri-urban slums of Karachi, Pakistan: a mixed-methods study

BACKGROUND

Great disparities in immunization coverage exist in Pakistan between urban and rural areas. However, coverage estimates for large peri-urban slums in Sindh are largely unknown and implementation challenges remain unexplored. This study explores key supply- and demand-side immunization barriers in peri-urban slums, as well as strategies to address them. It also assesses immunization coverage in the target slums.

METHODS

Conducted in four peri-urban slums in Karachi, this mixed-methods study consists of a baseline cross-sectional coverage survey of a representative sample of 840 caregivers of children aged 12-23 months, and 155 in-depth interviews (IDIs) through purposive sampling of respondents (caregivers, community influencers and immunization staff). After identifying the barriers, a further six IDIs were then conducted with immunization policy-makers and policy influencers to determine strategies to address these barriers, resulting in the development of an original validated implementation framework for immunization in peri-urban slums. A thematic analysis approach was applied to qualitative data.

RESULTS

The survey revealed 49% of children were fully vaccinated, 43% were partially vaccinated and 8% were unvaccinated. Demand-side immunization barriers included household barriers, lack of knowledge and awareness, misconceptions and fears regarding vaccines and social and religious barriers. Supply-side barriers included underperformance of staff, inefficient utilization of funds, unreliable immunization and household data and interference of polio campaigns with immunization. The implementation framework's policy recommendations to address these barriers include: (1) improved human resource management; (2) staff training on counselling; (3) re-allocation of funds towards incentives, outreach, salaries and infrastructure; (4) a digital platform integrating birth registry and vaccination tracking systems for monitoring and reporting by frontline staff; (5) use of digital platform for immunization targets and generating dose reminders; and (6) mutual sharing of resources and data between the immunization, Lady Health Worker and polio programmes for improved coverage.

CONCLUSIONS

The implementation framework is underpinned by the study of uncharted immunization barriers in complex peri-urban slums, and can be used by implementers in Pakistan and other developing countries to improve immunization programmes in limited-resource settings, with possible application at a larger scale. In particular, a digital platform integrating vaccination tracking and birth registry data can be expanded for nationwide use.

The extent to which the design of available reproductive health interventions fit the reproductive health needs of adolescents living in urban poor settings of Kisenyi, Kampala, Uganda

BACKGROUND

The rate at which informal urban settlements (slums) are developing in Low and Middle Income. Countries (LMICs) like Uganda is high. With this, comes the growing intersection between urbanization and the reproductive health of key populations. Currently, a number of interventions are being implemented to improve the Reproductive Health (RH) of adolescents in Kisenyi, the largest informal urban settlement in Kampala, the capital of Uganda. Despite these efforts, adolescent RH indicators have persistently remained poor in Kisenyi. This could be indicative of a gap between the provided and needed adolescent RH interventions. We assessed the fit between the available interventions and the RH needs of adolescents living in Kisenyi.

METHODS

We conducted a qualitative study in July 2019-February 2020 in Kisenyi. The methodology was guided by the Word Health Organization global standards for quality-health care services for adolescents, the "For whom? Where? By whom? and What?" Framework of sexual RH service delivery and the realist evaluation approach. Eight focus group discussions were conducted with adolescents 15-19 years to explore their RH needs. The design and implementation of the available adolescent RH interventions were assessed by conducting Key Informant interviews with 10 RH service providers in Kisenyi. Validation meetings were held with adolescents and they scored the extent to which the various design features of the existing interventions fit the adolescents' RH needs.

RESULTS

The available RH interventions focused on meeting the sexual RH needs like providing family planning services but less on social needs like livelihood and sanitation which the adolescents identified as equally important. While the providers designed intervention to target 10-24 year olds, the adolescents preferred to have interventions that specifically targeted the study population 15-19 years. Most interventions were facility-based while, the adolescents desired community based outreaches.

CONCLUSION

The packaging and mode of delivery of interventions were perceived less holistic to meet the adolescents' needs. Most interventions were designed to address the sexual and family planning needs while ignoring the wider social and livelihood needs. More holistic and outreach-based programming that addresses RH within the broader context of livelihood and sanitation requirements are more likely to be effective.

How does Covid-19 affect urban slums? Evidence from settlement leaders in India

Slum settlements have received significant attention for their vulnerabilities to the spread of Covid-19. To mitigate risks of transmission, and alleviate economic distress associated with containment measures, public health experts and international agencies are calling for community-driven solutions that harness local participation. In slum settlements, such approaches will encounter the informal slum leaders present across cities of the Global South. How are slum leaders positioned to address the health and livelihood threats of the pandemic within their neighborhoods? What problem-solving activities, if any, have they performed for residents during the pandemic? What factors shape success in those efforts? To answer these questions, we conducted a phone survey of 321 slum leaders across 79 slum settlements in two north Indian cities. The survey was conducted in April and May 2020, at the height of India's stringent national lockdown in response to the virus. Our survey reveals striking continuities with pre-pandemic politics. First, slum leaders persist in their problem-solving roles, even as they shift their efforts towards requesting urgently needed government relief (particularly food rations). Second, slum leaders vary in their reported ability to gather information about relief schemes, make claims, and command government responsiveness. The factors that inform the effectiveness of slum leaders during 'normal times', notably their education and degree of embeddedness in party networks, continue to do so during the lockdown. Slum leader reliance on partisan networks raises concerns regarding the inclusiveness of their efforts. Finally, slums are not uniformly challenged in maintaining social distancing. Pre-pandemic disparities in infrastructural development fragment the degree to which residents must depart from social distancing guidelines to secure essential services.

Use of alternative care sites during the COVID-19 pandemic in the city of Buenos Aires, Argentina

Objectives

In large cities, where a large proportion of the population live in poverty and overcrowding, orders to stay home to comply with isolation requirements are difficult to fulfil. In this article, the use of alternative care sites (ACSs) for the isolation of patients with confirmed COVID-19 or persons under investigation (PUI) in the City of Buenos Aires during the first wave of COVID-19 are described.

Study design

This is a cross-sectional study.

Methods

All patients with COVID-19 and PUI with insufficient housing resources who could not comply with orders to stay home and who were considered at low clinical risk in the initial triage were referred to refurbished hotels in the City of Buenos Aires (Ciudad Autónoma de Buenos Aires [CABA]). ACSs were divided into those for confirmed COVID-19 patients and those for PUI.

Results

From March to August 2020, there were 58,143 reported cases of COVID-19 (13,829 of whom lived in slums) in the CABA. For COVID-19 positive cases, 62.1% (n = 8587) of those living in slums and 21.4% (n = 9498) of those living outside the slums were housed in an ACS. In total, 31.1% (n = 18,085) of confirmed COVID-19 cases were housed in ACSs. In addition, 7728 PUI were housed (3178 from the slums) in an ACS. The average length of stay was 9.0 ± 2.5 days for patients with COVID-19 and 1.6 ± 0.7 days for PUI. For the individuals who were housed in an ACS, 1314 (5.1%) had to be hospitalised, 56 were in critical care units (0.22%) and there were 27 deaths (0.1%), none during their stay in an ACS.

Conclusions

Overall, about one-third of all people with COVID-19 were referred to an ACS in the CABA. For slum dwellers, the proportion was >60%. The need for hospitalisation was low and severe clinical events were rare. This strategy reduced the pressure on hospitals so their efforts could be directed to patients with moderate-to-severe disease.

Social determinants of mental health of women living in slum: a systematic review

OBJECTIVE

With the rise of urbanization globally, the problem of living in slums has become a problem for the civil society. As a vulnerable segment, women make up half of the population in these regions; therefore, women's mental health has always been a concern. The purpose of this study was to review the social determinants of mental health in women living in slum areas.

METHODS

We systematically reviewed articles published between 2009 and 2019 on the social determinants of women's mental health in SID, Magiran, Google scholar, PubMed, Scopus, Science Direct, Embase, MEDLINE, PsychINFO, and PsychARTICLES databases using MeSH keywords according to PRISMA guidelines. The quality of the studies was assessed depending on the type of study using Ottawa Newcastle" scale and Joanna Briggs Institute quality assessment tools. Finally, 23 studies were analyzed.

RESULTS

Different social determinants influenced the mental health of women living in slum areas. Among the structural determinants, the socioeconomic level had the highest frequency, and gender was in the second rank with the highest correlation with poorer women's mental health status. Among the intermediate determinants, living conditions, food insecurity, social capital, and social support were most frequently associated with mental health status.

CONCLUSION

Women living in slum areas are prone to developing mental disorders and poorer mental health; therefore, supporting these women and creating job opportunities to raise their incomes and, subsequently, improve their social, economic, and living conditions should be taken into consideration. In addition, this requires careful planning and comprehensive social support.

Crowding has consequences: Prevention and management of COVID-19 in informal urban settlements

COVID-19 spreads via aerosols, droplets, fomites and faeces. The built environment that facilitates crowding increases exposure and hence transmission of COVID-19 as evidenced by outbreaks in both cool-dry and hot-humid climates, such as in the US prison system and dormitories in Singapore, respectively. This paper explores how the built environment influences crowding and COVID-19 transmission, focusing on informal urban settlements (slums). We propose policy and practice changes that could reduce COVID-19 transmission. There are several issues on how COVID-19 affects informal urban settlements. Slum populations tend to be younger than the overall population. Lower numbers of older people lessen the morbidity and mortality of the pandemic in slum areas. Second, many slum populations are highly mobile. By returning to their ancestral villages residents can avoid the risks of overcrowding and reduce the population density in a given area but may spread COVID-19 to other areas. Third, detection and registration of COVID-19 cases depends on patients presenting to health care providers. If the risk of visiting a health care centre outweighs the potential benefits patients may prefer not to seek treatment. The control and prevention of COVID-19 in informal urban settlements starts with organizing community infrastructure for diagnosis and treatment and assuring that basic needs (food, water, sanitation, health care and public transport) are met during quarantine. Next, community members at highest risk need to be identified and protected. Low-income, informal settlements need to be recognized as a reservoir and source for persistent transmission. Solutions to overcrowding must be developed for this and future pandemics. In view of the constant risk that slums present to the entire population decisive steps need to be taken to rehabilitate and improve informal settlements, while avoiding stigmatization.

The impact of the livelihoods and income fortification and socio-civic transformation project on the quality of life, wellbeing, self-esteem, and quality of neighbourhood social environment among the youth in slum areas of in Kampala, Uganda

BACKGROUND

Various interventions to improve the quality of life (QoL) among slum dwellers across sub Saharan Africa have been implemented. However, the interventions impacts remain less understood. We assessed the impact of the Urban Program on Livelihoods and Income Fortification and Socio-civic Transformation (UPLIFT) project on QoL, psychological wellbeing, self-esteem, and the quality of neighbourhood social environment of young people aged 13-25 years in slum areas of Makindye and Nakawa Divisions in Kampala, Uganda.

METHODS

The study was designed as a mixed method evaluation using repeated cross-sectional survey and grounded theory in both the intervention and comparison communities. The intervention effect was estimated using the difference-in-differences Kernel propensity-score matching technique, with bootstrapping. The "rcs" option was used given that data were from repeated cross-sectional surveys. A thematic analysis was adopted for the qualitative data to triangulate and complement the quantitative data.

RESULTS

The UPLIFT project led to an improvement in QoL, psychological wellbeing, and self-esteem of young people. In terms of QoL, the project led to a six-percentage point increase in quality of living conditions scores (where higher scores reflect better living conditions; lower ones, worse living conditions). However, a negative effect was observed for personal independence whilst the project did not have any impact on social relations. In terms of self-esteem and psychological wellbeing, the project led to a 4.6-point increase in self-esteem scores, a 5.4-point increase in self-acceptance scores, a 5.3- point increase in purpose in life scores, a 5.7 - point increase in personal growth, and a 10.7-point increase in autonomy scores. However, the project had a negative effect on personal independence; and had no impact on environmental mastery and the quality of neighbourhood social environment.

CONCLUSION

Functional community-owned assets accumulation and capacity building initiatives for young people in slum areas improved their psychological wellbeing and quality of life. However, such initiatives do not appear to address social relationships and personal independence of young people in slum areas.

Violence against women in urban slums of India: A review of two decades of research

It is estimated that about one-third of women ever experienced violence in their lifetime. India has experienced steady urban growth accompanying increase of urban populations living in slums. Several studies have reported prevalence of various forms of violence in urban slums. To our knowledge, no systematic review has been conducted exclusively reporting violence against women in India's urban slums. The review aims to synthesise the studies of violence against women conducted in the last two decades (2000-2020). We searched PubMed, Scopus and other relevant search engines to identify articles published between years 2000 and 2020, which focused on Indian women slum dwellers' experiences of violence. We included 14 studies, which satisfied the inclusion criteria in this review. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol was used to assess the studies. The prevalence of any form of violence against women, as reported in the studies, ranged from 15% to 59.3%. The major risk factors identified were husband's alcohol abuse, women justifying the violence inflicted on then, low educational levels of both women and men, dowry issues, age difference between the spouses and termination of a previous pregnancy. It is evident from the review that urban slum women experience persistent violence.

Daily changes in household water access and quality in urban slums undermine global safe water monitoring programmes

Global drinking water monitoring programmes and studies on water quality in urban slums often overlook short-term temporal changes in water quality and health risks. The aim of this study was to quantify daily changes in household water access and quality in an urban slum in Malawi using a mixed-method approach. Household drinking water samples (n = 371) were collected and monitored for E. coli in tandem with a water access questionnaire (n = 481). E. coli concentrations in household drinking water changed daily, and no household had drinking water that was completely safe to drink every day. Seasonal changes in drinking water availability, intermittent supply, limited opening hours, and frequent breakdown of public water points contributed to poor access. Households relied on multiple water sources and regularly switched between sources to meet daily water needs. There were generally similar E. coli levels in water samples considered safe and unsafe by residents. This study provides the first empirical evidence that water quality, water access, and related health risks in urban slums change at much finer (daily) temporal scales than is conventionally monitored and reported globally. Our findings underscore that to advance progress towards Sustainable Development Goal (SDG) Target 6.1, it is necessary for global water monitoring initiatives to consider short-term changes in access and quality.

Nature of, and responses to key sexual and reproductive health challenges for adolescents in urban slums in sub-Saharan Africa: a scoping review

BACKGROUND

Addressing adolescents' sexual and reproductive health and rights (SRHR) requires an understanding of the socio-cultural and spatial settings within which they live. One setting of particular importance is the informal settlements or 'slums' that are gradually dominating the urban space. We undertook a scoping review and synthesis of existing evidence on adolescent SRHR in slums in sub-Saharan Africa (SSA) focusing on the characteristics and nature of existing evidence.

METHODS

The scoping review was conducted based on Arksey and O'Malley framework and in accordance with the guidance on scoping reviews from the Joanna Briggs Institute (JBI) and using PRISMA reporting guidelines for scoping reviews. A comprehensive search was undertaken in PubMed, POPLINE, African Journals Online (AJOL), Bioline International and Google Scholar. The search was confined to studies published in peer reviewed journals and reports published online between January 2000 and May 2019. Studies were included in the review if they addressed SRHR issues among adolescents living in urban slums in SSA.

RESULTS

The review included a total of 54 studies. The majority (79.5%) of studies were quantitative. The bulk of studies (85.2%) were observational studies with only eight intervention studies. While half (27) of the studies focused exclusively on adolescents (10-19 years), 12 studies combined adolescents with other young people (10-24 years). The studies were skewed towards sexual behavior (44%) and HIV/AIDS (43%) with very few studies focusing on other SRHR issues such as contraception, abortion, gender-based violence and sexually transmitted infections (STIs) other than HIV. Most of the studies highlighted the significantly higher risks for poor SRHR outcomes among adolescents in slums as compared to their peers in other settlements.

CONCLUSION

Young people growing up in slums face tremendous challenges in relation to their SRHR needs resulting in poor outcomes such as early and unintended pregnancy, STIs, and sexual violence. The results of this review point to several potential target areas for programming, policy, and research aimed at improved adolescent SRHR in slums in SSA.

Unmet need for family planning services among young married women (15-24 years) living in urban slums of India

BACKGROUND

NFHS-4 stated high unmet need for family planning (FP) among married women in Uttar Pradesh. Unmet need is highest among age groups: 15-19 and 20-24 years. Currently few data is available about unmet need for FP among vulnerable section of the community, i.e.15-24 year's age group living in the urban slums. Therefore this study was conducted to assess the unmet need for FP services and its determinants among this under-privileged and under-served section of society residing in urban slums of Uttar Pradesh, India.

METHODS

Cross sectional study was conducted in the slums of Lucknow, India. One Urban-Primary Health Centre (U-PHC) was randomly selected from each of the eight Municipal Corporation zones in Lucknow and two notified slums were randomly selected from each U-PHC. All the households in the selected slums were visited for interviewing 33 young married women (YMW) in each slum, with a pre-structured and pre tested questionnaire, to achieve the sample size of 535. Analysis of the data was done using logistic regression.

RESULTS

The unmet need for family planning services among YMW was 55.3%. About 40.9% of the unmet need was for spacing methods and 14.4% for limiting methods. Important reasons cited for unmet need for family planning services were negligent attitude of the women towards family planning, opposition by husband or others, embarrassment / hesitation / shyness for contraceptive use, poor knowledge of the FP method or availability of family planning services. Among method related reasons health concerns and fear of side effects were frequently cited reasons. On multiple logistic regression: age, educational status, duration of marriage, number of pregnancies, knowledge of contraceptive methods, opposition to contraceptive use and contact with Auxiliary Nurse Midwife (ANM) showed independently significant association with unmet need for family planning services.

CONCLUSIONS

Unmet need for family planning services is very high among the YMW of urban slums. The findings stress that program managers should take into cognizance these determinants of high level of unmet need for family planning among YMW and make intense efforts for addressing these issues in a holistic manner.

Slum Health: Arresting COVID-19 and Improving Well-Being in Urban Informal Settlements

The informal settlements of the Global South are the least prepared for the pandemic of COVID-19 since basic needs such as water, toilets, sewers, drainage, waste collection, and secure and adequate housing are already in short supply or non-existent. Further, space constraints, violence, and overcrowding in slums make physical distancing and self-quarantine impractical, and the rapid spread of an infection highly likely. Residents of informal settlements are also economically vulnerable during any COVID-19 responses. Any responses to COVID-19 that do not recognize these realities will further jeopardize the survival of large segments of the urban population globally. Most top-down strategies to arrest an infectious disease will likely ignore the often-robust social groups and knowledge that already exist in many slums. Here, we offer a set of practice and policy suggestions that aim to (1) dampen the spread of COVID-19 based on the latest available science, (2) improve the likelihood of medical care for the urban poor whether or not they get infected, and (3) provide economic, social, and physical improvements and protections to the urban poor, including migrants, slum communities, and their residents, that can improve their long-term well-being. Immediate measures to protect residents of urban informal settlements, the homeless, those living in precarious settlements, and the entire population from COVID-19 include the following: (1) institute informal settlements/slum emergency planning committees in every urban informal settlement; (2) apply an immediate moratorium on evictions; (3) provide an immediate guarantee of payments to the poor; (4) immediately train and deploy community health workers; (5) immediately meet Sphere Humanitarian standards for water, sanitation, and hygiene; (6) provide immediate food assistance; (7) develop and implement a solid waste collection strategy; and (8) implement immediately a plan for mobility and health care. Lessons have been learned from earlier pandemics such as HIV and epidemics such as Ebola. They can be applied here. At the same time, the opportunity exists for public health, public administration, international aid, NGOs, and community groups to innovate beyond disaster response and move toward long-term plans.

Operationalising a One Health approach to reduce the infection and antimicrobial resistance (AMR) burden in under-5 year old urban slum dwellers: The Childhood Infections and Pollution (CHIP) Consortium

The WHO advocates the use of a One Health approach to address antimicrobial resistance (AMR), focusing on integrating human, animal and environmental health factors. Nevertheless, there is a dearth of AMR research investigating the complexity of down and upstream factors across the One Health spectrum, especially in resource-deprived settings. The Childhood Infections and Pollution Consortium (CHIP) was designed to reduce the burden of childhood infections and AMR in urban slums, particularly in low-and middle-income countries, using One Health and technology-enabled Citizen Science approaches. Currently operationalized in three countries; India, Indonesia and Chile; CHIP is composed of interdisciplinary academics, healthcare professionals, veterinarians, international and local non-governmental organisations, current and former policymakers, local artists and community champions, amongst others. The CHIP Consortium invites collaborations for evidence-driven research, targeted investment and co-development of interventions in slums. We will host our third annual consortium workshop in Hong Kong in 2021 to build on our current work and explore new avenues to tackle childhood infections and AMR.

HIV testing experiences in Nairobi slums: the good, the bad and the ugly

Background

HIV testing is an integral component of HIV prevention, treatment and care and, therefore, is crucial in achieving UNAIDS 90–90-90 targets. HIV testing in Kenya follows both the voluntary counselling and testing (VCT) and provider initiated testing and counselling (PITC) models. However, little is known about the individual experiences of undergoing an HIV test in the two testing models. This study provides experiential evidence of undergoing an HIV test in a resource poor urban slum setting.

Methods

The study explored testing experiences and challenges faced in respect to ensuring the 3 Cs (consent, counselling and confidentiality), using in-depth interviews (N = 41) with HIV-infected men and women in two slum settlements of Nairobi City. The in-depth interview respondents were aged above 18 years with 56% being females. All interviews were audio-recorded, transcribed and then translated into English. The transcribed data were analysed using thematic analysis method.

Results

The respondent HIV-testing experiences were varied and greatly shaped by circumstances and motivation for HIV testing. The findings show both positive and negative experiences, with sporadic adherence to the 3Cs principle in both HIV testing models. Although some respondents were satisfied with the HIV testing process, a number of them raised a number of concerns, with instances of coercion and testing without consent being reported.

Conclusion

The 3Cs (consent, counselling and confidentiality) principle must underlie HIV testing and counselling practices in order to achieve positive testing outcomes. The study concludes that adherence to the 3Cs during HIV testing contributes to both the individual and public health good – irrespective of whether testing is initiated by the individual or by the health provider.

Review of drivers and barriers of water and sanitation policies for urban informal settlements in low-income and middle-income countries

This study examined drivers and barriers of water, sanitation, and hygiene (WASH) policies in urban informal settlements in low and middle-income countries. We conducted a search of peer-reviewed and grey literature published between January 2000 and April 2018. We organized evidence into six domains of drivers and barriers: economic, spatial, social, institutional, political, and informational. Key drivers included donor prioritization and collective action, while key barriers included social exclusion, lack of land or dwelling tenure status, the political economy of decision-making, and insufficient data. Ensuring responsive water and sanitation policies for informal settlements will require inter-disciplinary collaboration and both top-down and bottom-up approaches.

Coverage, quality, and correlates of childhood immunization in slums under national immunization program of India: A cross-sectional study

Adequate and quality immunization coverage plays a key role in controlling the outbreaks of vaccine preventable diseases. Places where immunization coverage is low, vaccine preventable diseases contribute to worse health outcomes. This is especially true in Indian slum dwellings where 33.0% of the urban population live. The aim of the study was to explore the coverage, quality, and correlates of primary immunization under national immunization program among children aged 12–23 months, living in slums of Mumbai. A community based cross-sectional survey was conducted. Parents or caretakers of 550 eligible children aged 12–23 months were interviewed using a structured interview schedule. Regression analysis was used to detect correlates of full immunization coverage (children who received one dose each of BCG, measles, and three doses each of DPT, OPV, and HBV by his/her first birthday) and of quality immunization coverage (children who received primary vaccines at appropriate age and intervals as mentioned above and had filled immunization card). Out of total 550 children, 402 (73.1%), 131 (23.8%), and 17 (3.1%) were fully, partially, and unimmunized, respectively. Almost 86.0% children received quality immunization coverage. In the regression analysis, reminder for immunization services was found to be the single most significant correlate of full and quality immunization coverage.

In this study, full immunization coverage was found to be below the expected level. This study also revealed that the awareness regarding the importance of adequate immunization was still lacking in the slum population. Emphasizing on reminders for immunization services, encouraging institutional deliveries, and scaling up use of postnatal care services may act as keys to improving the immunization coverage in Indian slums.

Acceptability and utilization of family planning benefits cards by youth in slums in Kampala, Uganda

BACKGROUND

This study was conducted to test the acceptability and utilization of family planning benefits cards (FPBCs) as incentives to increase family planning uptake among youth living in urban slums in Uganda.

METHODS

We conducted a one-year pilot study with two sub-studies on acceptability and utilization of FPBCs. The acceptability study utilized a quantitative cross-sectional design and was part of a baseline household survey while the utilization study was a primary analysis of claims and clinic data. We performed descriptive analyses and analyses of the association between different variables using binary logistic regression.

RESULTS

The acceptability study included 280 eligible females. The majority were married (52%), Christian (87%), and aged 20 and above (84%). Acceptability of the program was high (93%). Seventy-two percent of females used the card at least once to access reproductive health services. Twenty-seven percent of female users discontinued family planning and 14% changed family planning methods during the study. Female users of short-term contraceptive methods were 11 times more likely to discontinue use of FPBCs compared to those who used long-term methods (adjusted OR = 10.9, P = 0.011). Participants in professional/managerial employment were 30 times more likely to discontinue compared to the unemployed (adjusted OR = 30.3, P = 0.015). Participants of parity equal to two were 89% less likely to discontinue use of FPBCs compared to those of parity equal to zero (adjusted OR = 0.1, P = 0.019).

CONCLUSION

Family planning benefits cards, deployed as incentives to increase uptake of family planning, exhibited high acceptability and utilization by youth in urban slums in Uganda. There was evidence that use of short-term contraception methods, professional employment, and lower parity were associated with discontinuation of modern family planning methods after initial enrolment.

Analysing child linear growth trajectories among under-5 children in two Nairobi informal settlements

OBJECTIVE

We sought to identify factors associated with linear growth among under-5 children in two urban informal settlements in Nairobi.

DESIGN

We used longitudinal data for the period 2007-2012 from under-5 children recruited in the two sites between birth and 23 months and followed up until they reached 5 years of age. We fitted a generalized linear model on height-for-age Z-scores using the generalized estimating equations method to model linear growth trajectories among under-5 children. Known for its flexibility, the model provides strong parameter estimates and accounts for correlated observations on the same child.

SETTING

Two urban informal settlements in Nairobi, Kenya.ParticipantsUnder-5 children (n 1917) and their mothers (n 1679).

RESULTS

The findings show that child weight at birth, exclusive breast-feeding and immunization status were key determinants of linear growth among under-5 children. Additionally, maternal characteristics (mother's age, marital status) and household-level factors (socio-economic status, size of household) were significantly associated with child linear growth. There were biological differences in linear growth, as female children were more likely to grow faster than males. Finally, the model captured significant household-level effects to investigate further.

CONCLUSIONS

Findings from the study point to the need to improve the targeting of child health programmes directed at the urban poor population in Nairobi. Specific modifiable determinants of child linear growth, particularly child weight at birth, exclusive breast-feeding, immunization status and mother's background characteristics, should be considered when designing interventions aiming at addressing child health inequities in these settings.

The Risk of Tuberculosis among Populations Living in Slum Settings: a Systematic Review and Meta-analysis

According to the WHO, half of the 10.4 million incident cases of TB in 2016 came from five countries where 20-50% of the urban population live in slums. Crowded living conditions and limited access to healthcare further contribute to the burden of TB in urban slums. This article aims to assess the odds of the burden of TB in urban slums through a systematic review and meta-analysis. Four electronic databases were searched for studies published between 1993 and 2017, with TB defined as at least one sputum smear-positive. The review followed the PRISMA protocol and information was extracted from articles for a full-text review to determine eligibility. Odds ratios were calculated for studies reporting sputum smear-positive TB cases in slum settings with national incidence as a comparison. Summary estimates were calculated using the random effects model (95% CI) and publication bias was assessed through funnel plot analysis. A quality assessment of included articles was also conducted. This meta-analysis was conducted across three categories: (1) across all 22 studies, (2) studies utilizing Active Case Finding, and (3) studies conducted in a high TB-HIV setting. The odds of sputum smear-positive TB were significantly higher across all three categories of analysis. Compared with national TB incidence rates, the combined odds ratio of smear-positive TB within slums was 2.96 (2.84, 3.09; p < 0.01). The combined odds ratio for smear-positive TB with active case finding across 15 studies was 2.85 (2.71, 2.99; p < 0.01). Among the 11 studies that reported incidence of smear-positive TB with prevalent TB-HIV coinfection in the community, the combined odds ratio for slum residents with the random effects model was 2.48 (2.34, 2.63; p < 0.01). Using Egger's funnel plot, publication bias was not detected within the three categories of analysis. The findings of this analysis indicate that the odds of developing TB are almost five times as great in urban slums. Reaching the most vulnerable and often overlooked groups in slums is crucial to achieving the SDGs and End TB Strategy by 2035.

Barriers and opportunities for improving childhood immunization coverage in slums: A qualitative study

There is substantial variability in immunization coverage trends across the globe which can be attributed to a number of factors such as demographic profile, socioeconomic characteristics and political environment. Vaccine preventable diseases contribute to severe disease burden when coverage is low, particularly, in slums. Present qualitative study explored barriers, opportunities, and key facilitators of childhood immunization. This was a community based cross-sectional study conducted in the slum areas of Mumbai, India. Data from the observations of immunization sessions and interviews of end users, healthcare service providers, and influencers were collected and analyzed. Lack of time, poor awareness, fear of adverse event, loss of daily income, and migrant population were some of the major reasons to not get immunized. Also, lack of good behavior of staff was another crucial factor perceived by caretakers as barrier in the immunization. Stakeholders agreed that immunization is a shared responsibility involving community, service providers, and policy makers. There was general consensus that immunization practices have improved over the last few years. However, its positive impact is yet to be fully seen in populations that belong to lower socioeconomic strata, thus warranting additional efforts to improve the immunization coverage in slums. Effective communication, process improvement at various levels, active involvement of communities in the immunization activities, building trust and accountability, and constructive feedback are some of the essential elements to strengthen the immunization program. Strategies to improve immunization services in such settings should be based on interactions with stakeholders and understanding their perspectives.

Cardiovascular and other risk factors among people who live in slums in Buenos Aires, Argentina

OBJECTIVES

Effective planning of health policies requires the availability of accurate data, representing the burden of disease and risks to the diverse components of society. In Argentina, health information comes from the national risk factors survey (NRFS), which characterises the distribution of different risk factors. However, the NRFS has never collected information from residents living in slums, despite slums representing 10% of the population. The objective of this survey was to characterise the prevalence of cardiovascular and other risk factors among the inhabitants of one of the largest slums in Buenos Aires (Villa 31) and compare it to data from the NRFS.

STUDY DESIGN

This was a cross-sectional study.

METHODS

A cross-sectional study was carried out in 400 slum households, using the same data structure as the NRFS. The survey obtained information about economic aspects, reproductive health, addictions and risk factors. All participants had their blood pressure, weight and height measured. A total of 406 people were interviewed and their data were compared with data from 32,365 people in the NRFS. All comparisons were made on the basis of age group.

RESULTS

A fair/poor self-perceived level of health (odds ratio [OR] 3.19, 95% confidence interval [CI]: 2.60-3.91), anxiety and moderate to severe depression (OR 5.44, 95% CI: 4.43-6.69), problem drinking (OR 10.01, 95% CI 8.08-12.40), self-reported hypertension (OR 1.26, 95% CI: 1.01-1.57), overweight (OR 1.26, 95% CI: 1.03-1.55) and obesity (OR 1.72, 95% CI: 1.38-2.15) were significantly higher in the slum population. In people aged 18-24 years, the prevalence of diabetes was triple the national average (OR 3.17, 95% CI: 1.26-7.98). For all evaluated conditions in this study, the inhabitants of the slum received significantly less treatment compared with participants from the NRFS.

CONCLUSIONS

The prevalence of cardiovascular and other risk factors in the slum population has a different distribution to that reported in the NRFS. These data suggest the need to establish specific policies for slum populations.
