Aquino E. Do social protection programmes affect the burden of breast and cervical cancer? A systematic review

Background

Socioeconomic conditions are strongly associated with breast and cervical cancer incidence and mortality patterns; therefore, social protection programmes (SPPs) might impact these cancers. This study aimed to evaluate the effect of SPPs on breast and cervical cancer outcomes and their risk/protective factors.

Methods

Five databases were searched for articles that assessed participation in PPS and the incidence, survival, mortality (primary outcomes), screening, staging at diagnosis and risk/protective factors (secondary outcomes) for these cancers. Only peer-reviewed quantitative studies of women receiving SPPs compared to eligible women not receiving benefits were included. Independent reviewers selected articles, assessed eligibility, extracted data, and assessed the risk of bias. A harvest plot represents the included studies and shows the direction of effect, sample size and risk of bias.

Findings

Of 17,080 documents retrieved, 43 studies were included in the review. No studies evaluated the primary outcomes. They all examined the relationship between SPPs and screening, as well as risk and protective factors. The harvest plot showed that in lower risk of bias studies, participants of SPPs had lower weight and fertility, were older at sexual debut, and breastfed their infants for longer.

Interpretation

No studies have yet assessed the effect of SPPs on breast and cervical cancer incidence, survival, or mortality; nevertheless, the existing evidence suggests positive impacts on risk and protective factors.

An Early Warning Risk and Control Model for Manpower Capital Investment Using Data Warehousing and Computational Intelligence

Human capital plays an important role in the development of enterprises. Investing in human capital is the main focus of enterprises to improve personnel quality and enhance their core competitiveness. With the development of market economy, the function of human resource market allocation has been improved and the mobility of enterprise human resources has been enhanced leading to the increase in investment risk of enterprise human capital. Enterprise human capital investment risk has a negative impact on enterprises, reduces the income of enterprises' human capital investment, and affects their growth. Hence, enterprises need to avoid the risk of human capital investment or minimize the negative impact of risk. Using the data warehouse and computational intelligence, this paper constructs the early warning and control model for human capital investment risk and analyzes the existing approaches during the recruitment process and training, investment, and production, among enterprises. Finally, this paper proposes the corresponding control method according to the model inspiration.

Geospatial Distribution of Family Planning Services in Kira Municipality, Wakiso District, Uganda

Introduction: Access to family planning (FP) services remains a challenge, particularly in informal urban settlements. The unmet need for FP in these settings is high, with a correspondingly high prevalence of unintended pregnancies that may lead to unsafe abortions. However, there is a paucity of quality data on the distribution of FP services in such settings in Uganda. This paper described the geospatial distribution of FP services in Kira Municipality, Wakiso District, Uganda.

Methods: This was a cross-sectional study in which we determined the availability and distribution of FP services in Kira Municipality. Community mapping and analysis were conducted using ArcGIS (version 10.1) and ArcGIS Online. Stata version 13.1 was used for data analysis. Chi-square test was used to compare the contraceptive provision and availability among facilities from informal and formal settlements.

Results: Of the 176 healthcare facilities surveyed, only 42% (n = 74) offered contraceptives in informal settlements. The majority of the facilities were privately owned small clinics (95%). At least 80% of the facilities provided three or more modern contraceptive methods, with no difference (p = 0.107) between facilities in informal and formal settlements. Only 30.7% (p = 0.001) of the facilities provided at least one long-acting contraceptive. Similarly, 20 and 12% (p = 0.001) of the facilities had implants and intrauterine devices (IUDs) on the day of the survey. Almost 25% of the facilities did not offer contraceptive services (counseling and commodities) to unmarried adolescents.

Conclusions: Most facilities were small privately-owned clinics, offering at least three modern contraceptive methods. The unavailability of long-acting reversible methods in the informal settings may affect the quality of FP services due to limited choice. The inequity in service provision that disfavors the unmarried adolescent may increase unwanted/unintended pregnancies. We recommend that local governments and partners work toward filling the existing commodities gap and addressing the discrimination against unmarried adolescents in such settings.

Addressing Learner-Centred Barriers to Sexuality Education in Rural Areas of South Africa: Learners' Perspectives on Promoting Sexual Health Outcomes

INTRODUCTION

The school-based sexuality education programmes in South Africa aim to improve the sexual and reproductive health of school-going adolescents. However, the high rate of unplanned pregnancy and sexually transmitted infections among learners in some schools in rural areas of King Cetshwayo district suggests that the programmes in these schools might not be effective due to certain learner-centred factors.

METHOD

This qualitative study explored lived experiences of 84 learners from nine public schools in 2020 through focus group interviews. Data was analysed using Interpretative Phenomenological Analysis.

RESULTS

Learner-centred barriers to effective school-based sexuality education identified in this study were attitudes, age disparity, psychological status, peer pressure, socio-economic status, the exploratory attitude of learners, media, lack of role models, previous experiences, socio-economic status, and lack of parental love. These factors could reduce good sexual health. Learner-targeted interventions such as campaigns, using guest professionals, condom distribution, videos, on-site family planning, formal demonstrations, and on-site counselling could address these barriers.

CONCLUSIONS

Addressing these barriers and implementing the proposed interventions will enhance school-based sexuality education and consequently improve adolescents' sexual health.

POLICY IMPLICATIONS

The findings could guide programming, implementation, and delivery of school-based sexuality education leading to improved adolescents' sexual and reproductive health.

Sexual-risk behaviours and HIV and syphilis prevalence among in- and out-of-school adolescent girls and young women in Uganda: A cross-sectional study

Background

Adolescent girls and young women (AGYW) are at increased risk of sexually transmitted infections (STIs). We assessed sexual-risk behaviours and HIV and syphilis prevalence among AGYW in Uganda to inform the design of target-specific risk-reduction interventions.

Methods

This analysis utilizes data from 8,236 AGYW aged 10–24 years, collected in 20 districts, between July and August 2018. AGYW engaged in sexual-risk behaviour if they: a) reported a history of STIs; or b) had their sexual debut before age 15; or c) engaged in sex with 2+ partners in the past 12 months; or c) did not use or used condoms inconsistently with their most recent partners. We diagnosed HIV using Determine^TMHIV-1/2, Stat-Pak^TMHIV-1/2 and SD Bioline. We used SD Bioline Syphilis test kits to diagnose syphilis and Treponema Pallidum Hemagglutination Assay for confirmatory syphilis testing. Comparison of proportions was done using Chi-square (χ²) tests. Data were analysed using STATA (version 14.1).

Results

Of 4,488 AGYW (54.5%) that had ever had sex, 12.9% (n = 581) had their sexual debut before age 15; 19.1% (n = 858) reported a history of STIs. Of those that had ever had sex, 79.6% (n = 3,573) had sex in the 12 months preceding the survey; 75.6% (n = 2,707) with one (1) and 24.2% (n = 866) with 2+ partners. Condom use with the most recent sexual partner was low, with only 20.4% (n = 728) reporting consistent condom use while 79.6% (n = 2,842) reported inconsistent or no condom use. In-school AGYW were significantly less likely to have ever had sex (35.6% vs. 73.6%, P<0.001), to have had sexual debut before age 15 (7.7% vs. 15.5%, P<0.001) or to engage in sex with 2+ partners (5.3% vs. 15.8%, P<0.001). Consistent condom use was significantly higher among in-school than out-of-school AGYW (40.1% vs. 12.7%, P<0.001). Overall, 1.7% (n = 143) had HIV while 1.3% (n = 104) had syphilis. HIV and syphilis prevalence was higher among out-of-school than in-school AGYW (HIV: 2.6% vs. 0.9%; syphilis: 2.1% vs. 0.5%, respectively).

Conclusion

In-school AGYW engaged in more protective sexual behaviors and had less HIV and syphilis than their out-of-school counterparts. These findings suggest a need for target-specific risk-reduction interventions stratified by schooling status.

Intervening for HIV prevention and mental health: a review of global literature

INTRODUCTION

Numerous effective HIV prevention options exist, including behaviour change interventions, condom promotion and biomedical interventions, like voluntary medical male circumcision and pre-exposure prophylaxis. However, populations at risk of HIV also face overlapping vulnerabilities to common mental disorders and severe mental illness. Mental health status can affect engagement in HIV risk behaviours and HIV prevention programmes. We conducted a narrative review of the literature on HIV prevention among key populations and other groups vulnerable to HIV infection to understand the relationship between mental health conditions and HIV prevention outcomes and summarize existing evidence on integrated approaches to HIV prevention and mental healthcare.

METHODS

We searched five databases for studies published from January 2015 to August 2020, focused on HIV prevention and mental health conditions among key populations and individuals with serious mental illness. Studies were included if they evaluated an HIV prevention intervention or assessed correlates of HIV risk reduction and included assessment of mental health conditions or a mental health intervention.

RESULTS AND DISCUSSION

We identified 50 studies meeting our inclusion criteria, of which 26 were randomized controlled trials or other experimental designs of an HIV prevention intervention with or without a mental health component. Behaviour change interventions were the most common HIV prevention approach. A majority of studies recruited men who have sex with men and adolescents. Two studies provided distinct approaches to integrated HIV prevention and mental health service delivery. Overall, a majority of included studies showed that symptoms of mental disorder or distress are associated with HIV prevention outcomes (e.g. increased risky sexual behaviour, poor engagement in HIV prevention behaviours). In addition, several studies conducted among groups at high risk of poor mental health found that integrating a mental health component into a behaviour change intervention or linking mental health services to combination prevention activities significantly reduced risk behaviour and mental distress and improved access to mental healthcare.

CONCLUSIONS

Evidence suggests that mental health conditions are associated with poorer HIV prevention outcomes, and tailored integrated approaches are urgently needed to address overlapping vulnerabilities among key populations and other individuals at risk.

Spillover HIV prevention effects of a cash transfer trial in East Zimbabwe: evidence from a cluster-randomised trial and general-population survey

BACKGROUND

Benefits of cash transfers (CTs) for HIV prevention have been demonstrated largely in purposively designed trials, commonly focusing on young women. It is less clear if CT interventions not designed for HIV prevention can have HIV-specific effects, including adverse effects. The cluster-randomised Manicaland Cash Transfer Trial (2010-11) evaluated effects of CTs on children's (2-17 years) development in eastern Zimbabwe. We evaluated whether this CT intervention with no HIV-specific objectives had unintended HIV prevention spillover effects (externalities).

METHODS

Data on 2909 individuals (15-54 years) living in trial households were taken from a general-population survey, conducted simultaneously in the same communities as the Manicaland Trial. Average treatment effects (ATEs) of CTs on sexual behaviour (any recent sex, condom use, multiple partners) and secondary outcomes (mental distress, school enrolment, and alcohol/cigarette/drug consumption) were estimated using mixed-effects logistic regressions (random effects for study site and intervention cluster), by sex and age group (15-29; 30-54 years). Outcomes were also evaluated with a larger synthetic comparison group created through propensity score matching.

RESULTS

CTs did not affect sexual debut but reduced having any recent sex (past 30 days) among young males (ATE: - 11.7 percentage points [PP] [95% confidence interval: -26.0PP, 2.61PP]) and females (- 5.68PP [- 15.7PP, 4.34PP]), with similar but less uncertain estimates when compared against the synthetic comparison group (males: -9.68PP [- 13.1PP, - 6.30PP]; females: -8.77PP [- 16.3PP, - 1.23PP]). There were no effects among older individuals. Young (but not older) males receiving CTs reported increased multiple partnerships (8.49PP [- 5.40PP, 22.4PP]; synthetic comparison: 10.3PP (1.27PP, 19.2PP). No impact on alcohol, cigarette, or drug consumption was found. There are indications that CTs reduced psychological distress among young people, although impacts were small. CTs increased school enrolment in males (11.5PP [3.05PP, 19.9PP]). Analyses with the synthetic comparison group (but not the original control group) further indicated increased school enrolment among females (5.50PP [1.62PP, 9.37PP]) and condom use among younger and older women receiving CTs (9.38PP [5.90PP, 12.9PP]; 5.95PP [1.46PP, 10.4PP]).

CONCLUSIONS

Non-HIV-prevention CT interventions can have HIV prevention outcomes, including reduced sexual activity among young people and increased multiple partnerships among young men. No effects on sexual debut or alcohol, cigarette, or drug consumption were observed. A broad approach is necessary to evaluate CT interventions to capture unintended outcomes, particularly in economic evaluations.

The influence of cash transfers on engagement in transactional sex and partner choice among adolescent girls and young women in Northwest Tanzania

Cash transfers are theorised to reduce adolescent girls and young women's economic vulnerability and engagement in transactional sex; however, the processes involved remain unclear. We conducted longitudinal cross-sectional, and narrative timeline in-depth interviews with young women aged 15-23 years in northern Tanzania enrolled in a cash transfer intervention. We analysed data using a thematic approach guided by the transactional sex framework. We summarised data and compared findings to the domains of the framework. Participants reported relationships in the 'sex and material expression of love' domain characterised by emotional intimacy and loose ties between material support and sex, and the 'sex for basic needs' domain characterised by limited emotional intimacy, economic vulnerability, and a clear exchange between material support and sex. Some participants expressed that cash transfers provided business capital and savings which enabled them to decrease 'sex for basic needs'. Cash transfers influenced transactional sex engagement by altering partner selection criteria such as from an emphasis on what men could provide to a focus on relationship stability. Findings suggest that cash transfers have the potential to reduce young women's transactional relationships motivated by economic vulnerability.

The Impact of a Conditional Cash Transfer on Multidimensional Deprivation of Young Women: Evidence from South Africa's HTPN 068

Despite the growing popularity of multidimensional poverty measurement and analysis, its use to measure the impact of social protection programs remains scarce. Using primary data collected for the evaluation of HIV Prevention Trials Network (HPTN) 068, a randomized, conditional cash transfer intervention for young girls in South Africa that ran from 2011 to 2015, we construct an individual-level measure of multidimensional poverty, a major departure from standard indices that use the household as the unit of analysis. We construct our measure by aggregating multiple deprivation indicators across six dimensions and using a system of nested weights where each domain is weighted equally. Our findings show that the cash transfer consistently reduces deprivations among girls, in particular through the domains of economic agency, violence, and relationships. These results show how social protection interventions can improve the lives of young women beyond single domains and demonstrate the potential for social protection to simultaneously address multiple targets of the SDGs.

Decision-making and cash spending patterns of adolescent girls and young women participating in a cash-transfer intervention in Tanzania: Implications for sexual health

Although cash transfers (CT) have been recommended as a strategy to address structural drivers of HIV, the evidence of the effects of CT on sexual risk and HIV outcomes is mixed. This could partly be due to CT implementation dynamics and beneficiary interpersonal factors. We conducted an assessment of CT component of the DREAMS programme in Tanzania. We explored how AGYW spent their CT over time, to whom they disclosed cash receipt, and where they sought advice on CT use. The study employed qualitative research methods including: 20 longitudinal in-depth interviews (IDIs) and 60 cross-sectional IDIs with AGYW in the CT programme. Data were analysed thematically. AGYW use of CT fell into five categories: business development, survival, self-care, helping family, and savings. The primary uses of CT funds were investment in businesses and livestock for savings. AGYW use of cash changed over instalments. AGYW consulted a variety of sources when deciding on how to use the cash, primarily mothers, programme personnel, and long-term partners/husbands. CT programmes that give cash directly to AGYW and have a strong entrepreneurial mentorship component could have implications for HIV prevention, SRH, and overall social and economic development.

Cash plus: exploring the mechanisms through which a cash transfer plus financial education programme in Tanzania reduced HIV risk for adolescent girls and young women

INTRODUCTION

Cash transfers have been promoted as a means to reduce HIV risk for adolescent girls and young women (AGYW) in sub-Saharan Africa. One of the main mechanisms whereby they are hypothesized to reduce risk is by deterring transactional sex. In this paper, we use qualitative methods to explore participant experiences, perspectives and reported behaviours of a cash transfer plus financial education programme among out of school, 15- to 23-year-old AGYWs in rural Tanzania with a focus on partner choice and transactional sex.

METHODS

We conducted 60 in-depth interviews (IDIs) and 20 narrative timeline interviews with participants of the PEPFAR DREAMS Sauti/WORTH+ cash transfer programme between June 2017 and July 2018. Interviews were taped, transcribed and translated from Kiswahili to English. Transcripts were coded and analysed for key themes.

RESULTS

We found that participants in a cash transfer plus programme discussed behaviours that could reduce HIV risk through decreasing their dependence on male sex partners. There appeared to be two main mechanisms for this. One, young women discussed the cash transfer providing for basic needs (e.g. food, toiletries) which appeared to reduce their dependence on male sex partners who previously provided these goods (e.g. transactional sex). This experience was more pronounced among the poorest participants. Two, young women discussed how the financial education/business development aspect of the programme empowered them to refuse some sex partners; unmarried women discussed these experiences more than married women. Social support from family and programme mentors appeared to strengthen young women's ability to successful start businesses, produce income and thus be less dependent on partners.

CONCLUSIONS

The cash transfer programme may have reduced AGYW engagement in transactional sex that occurred to meet basic needs (one form of transactional sex). The financial education/business development and mentorship elements of the programme appeared important in building AGYW agency, self-esteem and future orientation which may support AGYWs in refusing unwanted sex partners. Future cash plus programmes should consider adding or strengthening financial education and job skills training, mentorship and future orientation to see stronger and perhaps sustainable outcomes for HIV prevention.

Impact of the adolescent and youth sexual and reproductive health strategy on service utilisation and health outcomes in Zimbabwe

Poor reproductive health among youth and adolescents threatens their future health and economic wellbeing in Zimbabwe amidst a high HIV/AIDS prevalence. This study evaluates the impact of a multi-pronged adolescent sexual and reproductive health (ASRH) strategy implemented by government of Zimbabwe between 2010 and 2015 to improve ASRH in terms of the uptake of condoms and HIV testing as well as outcomes in terms of sexually transmitted infection (STI) prevalence and HIV prevalence. We combine the difference in difference and propensity score matching methods to analyse repeated Zimbabwe demographic health survey cross-sectional datasets. Young people aged 15–19 years at baseline in 2010, who were exposed for the entire five-year strategy are designated as the treatment group and young adults aged 25–29 at baseline as the control. We find that the ASRH strategy increased HIV testing amongst youth by 36.6 percent, whilst treatment of STIs also increased by 30.4 percent. We also find that the HIV prevalence trajectory was reduced by 0.7 percent. We do not find evidence of impact on condom use and STI prevalence. The findings also suggest that although HIV testing increased for all socio-economic groups that were investigated, the effect was not the same. Lastly, we do not find evidence supporting that more resources translate to better ASRH outcomes. We recommend designing future ASRH strategies in a way that differentiates service delivery for youths in HIV hotspots, rural areas and out of school. We also recommend improving the strategy’s coordination and monitoring, as well as aligning and enforcing government policies that promote sexual and reproductive health rights.

Strength-based interventions for HIV prevention and sexual risk reduction among girls and young women: A resilience-focused systematic review

Despite significant public health efforts, girls and young women still face gender-specific barriers to achieving optimal physical and mental health. Public health interventions have historically addressed the health needs of girls and young women using risk-focused, or deficit-based, approaches. Emerging research in public health and prevention provides an alternative approach, focusing instead on strengths and resilience. However, evidence remains limited regarding strength-based interventions to improve health outcomes for young women, including outcomes within the critically important areas of sexual and reproductive health. To address this gap in evidence, this review analyses the evidence base for intervention research using a strength-based resilience-focused approach to reduce HIV and sexual risk for girls and young women globally. A systematic search of published literature identified 35 articles, representing 25 unique interventions (N = 25). These interventions employed in-person, and other engaging methods, to deliver intervention content aimed at fostering resilience and changing sexual risk behaviours. Results also highlight gaps in measurement and study design, as well as variation in geographic setting and level of behaviour change. This review draws attention to the potential growth of strength-based intervention research, and offers future directions for developing and expanding research on resilience as an urgent global public health priority.

The impact of cash transfers on social determinants of health and health inequalities in sub-Saharan Africa: a systematic review

Cash transfers (CTs) are now high on the agenda of most governments in low- and middle-income countries. Within the field of health promotion, CTs constitute a healthy public policy initiative as they have the potential to address the social determinants of health (SDoH) and health inequalities. A systematic review was conducted to synthesise the evidence on CTs' impacts on SDoH and health inequalities in sub-Saharan Africa, and to identify the barriers and facilitators of effective CTs. Twenty-one electronic databases and the websites of 14 key organizations were searched in addition to grey literature and hand searching of selected journals for quantitative and qualitative studies on CTs' impacts on SDoH and health outcomes. Out of 182 full texts screened for eligibility, 79 reports that reported findings from 53 studies were included in the final review. The studies were undertaken within 24 CTs comprising 11 unconditional CTs (UCTs), 8 conditional CTs (CCTs) and 5 combined UCTs and CCTs. The review found that CTs can be effective in tackling structural determinants of health such as financial poverty, education, household resilience, child labour, social capital and social cohesion, civic participation, and birth registration. The review further found that CTs modify intermediate determinants such as nutrition, dietary diversity, child deprivation, sexual risk behaviours, teen pregnancy and early marriage. In conjunction with their influence on SDoH, there is moderate evidence from the review that CTs impact on health and quality of life outcomes. The review also found many factors relating to intervention design features, macro-economic stability, household dynamics and community acceptance of programs that could influence the effectiveness of CTs. The external validity of the review findings is strong as the findings are largely consistent with those from Latin America. The findings thus provide useful insights to policy makers and managers and can be used to optimise CTs to reduce health inequalities.

Evaluation of cash transfer programs in sub-Saharan Africa: A methodological review

Cash transfer programs (CTs) have been rigorously evaluated since their inception in the 1990s. However, to date, there has been no study critically examining the utility of the methodological approaches used to evaluate CTs. This article reviews the approaches used to evaluate CTs in sub-Saharan Africa (SSA) to provide recommendations for improving future CTs evaluations. We conducted searches for CTs evaluation studies in SSA in the peer-reviewed and grey literature using electronic databases, hand searching of selected journals, organisational websites, Google Scholar and Scirus Internet search engines. The review included 53 evaluation studies which were largely outcome-focused evaluations (95%; n = 50). The studies were undertaken within 24 CT programs comprising 11 unconditional CTs (UCTs), eight conditional CTs (CCTs) and five combined UCTs and CCTs. The review finds that while there is evidence of CTs impacts on a broad range of outcomes, the current evaluation approaches have primarily been experimental designs and have largely failed to provide explanations for mechanisms of change. To improve CTs policy and practice, there is the need to consider theory-based evaluation approaches such as realist evaluation that provide insights about the contexts and mechanisms through which programs generate outcomes in different circumstances.

The role of productive activities in the lives of adolescents: Photovoice evidence from Malawi

Adolescence is an important transitional period, separate from both childhood and adulthood. Critical physical and mental development occurs during adolescence, including emotional skills, physical, and mental abilities. Behaviors adopted during this lifecourse period have critical implications for adolescents' future health and well-being. The main research question of the present study is: what is the role of productive activities in the lives and development of adolescents in rural Malawi? As part of this study, selected adolescents from poor rural households were asked to take photographs of their daily (productive) activities. These photographs served as a starting point for focus group discussions. In addition to including adolescents, we conducted qualitative interviews with caregivers and teachers to triangulate and obtain a more holistic understanding of adolescent engagement in productive activities. The main themes that emerged were that 1) the work that is conducted by adolescent boys and girls inside and outside the household is not only perceived by adolescents as a product of poverty, but as a point of pride, as well as a potential means of providing for one's future, 2) there is a tension between the needs of the family and schooling, and 3) adolescent productive activities are associated with minor although not negligible hazards and injuries. We discuss that these qualitative findings help to better understand how social protection interventions, such as Malawi's Social Cash Transfer Program, may affect adolescent engagement in work and adolescent wellbeing more generally.

Unconditional cash transfers for reducing poverty and vulnerabilities: effect on use of health services and health outcomes in low- and middle-income countries

BACKGROUND

Unconditional cash transfers (UCTs; provided without obligation) for reducing poverty and vulnerabilities (e.g. orphanhood, old age or HIV infection) are a type of social protection intervention that addresses a key social determinant of health (income) in low- and middle-income countries (LMICs). The relative effectiveness of UCTs compared with conditional cash transfers (CCTs; provided so long as the recipient engages in prescribed behaviours such as using a health service or attending school) is unknown.

OBJECTIVES

To assess the effects of UCTs for improving health services use and health outcomes in vulnerable children and adults in LMICs. Secondary objectives are to assess the effects of UCTs on social determinants of health and healthcare expenditure and to compare to effects of UCTs versus CCTs.

SEARCH METHODS

We searched 17 electronic academic databases, including the Cochrane Public Health Group Specialised Register, the Cochrane Database of Systematic Reviews (the Cochrane Library 2017, Issue 5), MEDLINE and Embase, in May 2017. We also searched six electronic grey literature databases and websites of key organisations, handsearched key journals and included records, and sought expert advice.

SELECTION CRITERIA

We included both parallel group and cluster-randomised controlled trials (RCTs), quasi-RCTs, cohort and controlled before-and-after (CBAs) studies, and interrupted time series studies of UCT interventions in children (0 to 17 years) and adults (18 years or older) in LMICs. Comparison groups received either no UCT or a smaller UCT. Our primary outcomes were any health services use or health outcome.

DATA COLLECTION AND ANALYSIS

Two reviewers independently screened potentially relevant records for inclusion criteria, extracted data and assessed the risk of bias. We tried to obtain missing data from study authors if feasible. For cluster-RCTs, we generally calculated risk ratios for dichotomous outcomes from crude frequency measures in approximately correct analyses. Meta-analyses applied the inverse variance or Mantel-Haenszel method with random effects. We assessed the quality of evidence using the GRADE approach.

MAIN RESULTS

We included 21 studies (16 cluster-RCTs, 4 CBAs and 1 cohort study) involving 1,092,877 participants (36,068 children and 1,056,809 adults) and 31,865 households in Africa, the Americas and South-East Asia in our meta-analyses and narrative synthesis. The 17 types of UCTs we identified, including one basic universal income intervention, were pilot or established government programmes or research experiments. The cash value was equivalent to 1.3% to 53.9% of the annualised gross domestic product per capita. All studies compared a UCT with no UCT, and three studies also compared a UCT with a CCT. Most studies carried an overall high risk of bias (i.e. often selection and/or performance bias). Most studies were funded by national governments and/or international organisations.Throughout the review, we use the words 'probably' to indicate moderate-quality evidence, 'may/maybe' for low-quality evidence, and 'uncertain' for very low-quality evidence. UCTs may not have impacted the likelihood of having used any health service in the previous 1 to 12 months, when participants were followed up between 12 and 24 months into the intervention (risk ratio (RR) 1.04, 95% confidence interval (CI) 1.00 to 1.09, P = 0.07, 5 cluster-RCTs, N = 4972, I² = 2%, low-quality evidence). At one to two years, UCTs probably led to a clinically meaningful, very large reduction in the likelihood of having had any illness in the previous two weeks to three months (odds ratio (OR) 0.73, 95% CI 0.57 to 0.93, 5 cluster-RCTs, N = 8446, I² = 57%, moderate-quality evidence). Evidence from five cluster-RCTs on food security was too inconsistent to be combined in a meta-analysis, but it suggested that at 13 to 24 months' follow-up, UCTs could increase the likelihood of having been food secure over the previous month (low-quality evidence). UCTs may have increased participants' level of dietary diversity over the previous week, when assessed with the Household Dietary Diversity Score and followed up 24 months into the intervention (mean difference (MD) 0.59 food categories, 95% CI 0.18 to 1.01, 4 cluster-RCTs, N = 9347, I² = 79%, low-quality evidence). Despite several studies providing relevant evidence, the effects of UCTs on the likelihood of being moderately stunted and on the level of depression remain uncertain. No evidence was available on the effect of a UCT on the likelihood of having died. UCTs probably led to a clinically meaningful, moderate increase in the likelihood of currently attending school, when assessed at 12 to 24 months into the intervention (RR 1.06, 95% CI 1.03 to 1.09, 6 cluster-RCTs, N = 4800, I² = 0%, moderate-quality evidence). The evidence was uncertain for whether UCTs impacted livestock ownership, extreme poverty, participation in child labour, adult employment or parenting quality. Evidence from six cluster-RCTs on healthcare expenditure was too inconsistent to be combined in a meta-analysis, but it suggested that UCTs may have increased the amount of money spent on health care at 7 to 24 months into the intervention (low-quality evidence). The effects of UCTs on health equity (or unfair and remedial health inequalities) were very uncertain. We did not identify any harms from UCTs. Three cluster-RCTs compared UCTs versus CCTs with regard to the likelihood of having used any health services, the likelihood of having had any illness or the level of dietary diversity, but evidence was limited to one study per outcome and was very uncertain for all three.

AUTHORS' CONCLUSIONS

This body of evidence suggests that unconditional cash transfers (UCTs) may not impact a summary measure of health service use in children and adults in LMICs. However, UCTs probably or may improve some health outcomes (i.e. the likelihood of having had any illness, the likelihood of having been food secure, and the level of dietary diversity), one social determinant of health (i.e. the likelihood of attending school), and healthcare expenditure. The evidence on the relative effectiveness of UCTs and CCTs remains very uncertain.

Young people's and stakeholders' perspectives of adolescent sexual risk behavior in Kilifi County, Kenya: A qualitative study

A lack of research exists around the most common forms of sexual risk behaviors among adolescents, including their underlying factors, in Sub-Saharan Africa. Using an Ecological Model of Adolescent Behavior, we explore the perceptions of 85 young people and 10 stakeholders on sexual risk behavior of adolescents in Kilifi County on the coast of Kenya. Our findings show that transactional sex, early sexual debut, coerced sex, and multiple sexual partnerships are prevalent. An urgent need exists to develop measures to counter sexual risk behaviors. The results contribute to understanding the range of risks and protective factors in differing contexts, tackling underlying issues at individual, family, local institutional, wider socio-economic, and political levels.
