Effect of household relocation on child vaccination and health service utilisation in Dhaka, Bangladesh: a cross-sectional community survey

Factors associated with immunization status among children aged 12-59 months in Lagelu local government area, Ibadan: a cross-sectional study

Introduction

childhood deaths from preventable causes remain high in Nigeria. Although vaccines are available to combat many of these diseases, vaccine coverage remains low in many at-risk communities. With this study, we aimed to determine factors that might have impacted the use of immunization services in Ibadan, the capital of Oyo State in southwest Nigeria.

Methods

we conducted a community-based cross-sectional study in a peri-urban local government area in Ibadan using a multi-stage cluster sampling technique to identify respondents for this study. The interviewer-administered questionnaire was used to obtain information on respondents and child socio-demographic details. We reviewed the child´s vaccine card to determine vaccine status. Data were analyzed using STATA version 14 at a 5% level of significance.

Results

of the 265 children aged 12 to 59 months who had their vaccine cards appropriately filled, only 65.3% (n=173) received all basic vaccines, while 90.2% (n=239) and 86.8% (n=230) received 3 doses of pentavalent vaccine (PENTA) and pneumococcal conjugate vaccines (PCV-10) respectively. We found a significant difference in the completion of basic vaccination according to the caregiver´s place of residence and the mother´s educational level. Access-related barriers were frequently reported (n=24, 54.5%) as reasons for missing a due vaccine.

Conclusion

improvement in vaccine coverage in this setting is necessary. Targeted health information for mothers may be a cost-efficient and sustainable approach to improve vaccine coverage for under-five children.

Factors associated with accessing and utilisation of healthcare and provision of health services for residents of slums in low and middle-income countries: a scoping review of recent literature

OBJECTIVE

To identify factors associated with accessing and utilisation of healthcare and provision of health services in slums.

DESIGN

A scoping review incorporating a conceptual framework for configuring reported factors.

DATA SOURCES

MEDLINE, Embase, CINAHL, Web of Science and the Cochrane Library were searched from their inception to December 2021 using slum-related terms.

ELIGIBILITY CRITERIA

Empirical studies of all designs reporting relevant factors in slums in low and middle-income countries.

DATA EXTRACTION AND SYNTHESIS

Studies were categorised and data were charted according to a preliminary conceptual framework refined by emerging findings. Results were tabulated and narratively summarised.

RESULTS

Of the 15 469 records retrieved from all years, 4368 records dated between 2016 and 2021 were screened by two independent reviewers and 111 studies were included. The majority (63 studies, 57%) were conducted in Asia, predominantly in India. In total, 104 studies examined healthcare access and utilisation from slum residents' perspective while only 10 studies explored provision of health services from providers/planners' perspective (three studies included both). A multitude of factors are associated with accessing, using and providing healthcare in slums, including recent migration to slums; knowledge, perception and past experience of illness, healthcare needs and health services; financial constraint and competing priorities between health and making a living; lacking social support; unfavourable physical environment and locality; sociocultural expectations and stigma; lack of official recognition; and existing problems in the health system.

CONCLUSION

The scoping review identified a significant body of recent literature reporting factors associated with accessing, utilisation and provision of healthcare services in slums. We classified the diverse factors under seven broad categories. The findings can inform a holistic approach to improving health services in slums by tackling barriers at different levels, taking into account local context and geospatial features of individual slums.

Residential mobility and potentially avoidable hospitalisations in a population-based cohort of New Zealand children

BACKGROUND

Residential moves are common in early childhood and associations have been found between residential mobility and adverse child health and well-being outcomes. Although there are studies on potentially avoidable hospitalisations (PAH) in children, few have examined PAH in relation to residential mobility. Our aim, therefore, was to investigate residential mobility and PAH in a population-based cohort of New Zealand children.

METHODS

Using a retrospective cohort design, we analysed data from the Integrated Data Infrastructure for a cohort of 314 283 children born since the start of 2004, who had at least one residential address recorded by 2 years of age. Residential mobility was derived from address data and PAH were determined from hospital discharge data.

RESULTS

Half of the cohort children (52%) experienced at least one residential move by 2 years of age, and 22% experienced two or more moves. Fifteen per cent of the cohort experienced one or more PAH between 2 and 4 years of age. A linear association between residential mobility and PAH was found (relative risk (RR)=1.18, CI 1.17 to 1.19) and this remained robust when adjusting for several covariates. Sensitivity analyses for ambulatory care sensitive hospitalisations (ACSH) and PAH attributable to the housing/physical environment (PAH-HE) produced results very similar to those for PAH (ACSH: adjusted RR (aRR)=1.10, CI 1.09 to 1.11; PAH-HE: aRR=1.11, CI 1.10 to 1.12).

CONCLUSION

This study found a linear association between higher residential mobility and an increased likelihood of PAH in young children. Avenues for further investigation are suggested.

A systematic review of the health of internal migrants in Bangladesh

Internal migrants are more disadvantaged than non-migrants in terms of their health. However, the extent of this difference is unclear. Following the PRISMA guideline, we conducted a systematic review to explore the existing evidence on the health of internal migrants of Bangladesh. We searched Pubmed, Web of Science and Google Scholar to identify peer-reviewed literature on health related issues of the internal migrant population and identified 29 papers for inclusion. Included studies reported health issues or risk factors relating to water, sanitisation and hygiene access and practice, risky sexual behaviour and sexually transmitted infection, mental health status, occupational health status, general healthcare availability, healthcare service utilisation and healthcare seeking behaviour. This systematic review reveals that research on health issues of internal migrants of Bangladesh is limited for common communicable and noncommunicable diseases like waterborne and skin disease, tuberculosis, hypertension and diabetes. Further, despite that many of these migrants are labourers, occupational health related issues like work place accidents, musculoskeletal disorders are insufficiently explored. Barriers to healthcare accessibility in this population are poor socioeconomic status, illiteracy and low general health knowledge. For improved development and implementation of health policies targeting this important population, future studies should focus on understudied diseases and disease prevalence and be designed to elicit from the perspectives of internal migrants, their key health needs around risk factors and health services accessibility.
