Assessing Africa's child survival gains and prospects for attaining SDG target on child mortality.

This study assessed Africa's child survival gains and prospects for attaining Sustainable Development Goals (SDG) target 3.2. We analysed multiple country-level secondary datasets of 54 African countries and presented spatial analysis. Results showed that only 8 out of the 54 African countries have achieved substantial reductions in under-5 mortality with an under-five mortality rate (U5MR) of 25 deaths per 1,000 live births or less. Many countries are far from achieving this target. Results of the predictions using supervised machine learning on the Bayesian network reveal that the probability of achieving the SDG target 3.2 (i.e., having U5MR of 25 deaths per 1000 live births or less) increases (from 21.6% to 100%) when the contraceptive prevalence increases from 49.8% to 78.5%; and the use of skilled birth attendants increases from 44.8% to 86.3%; and percentage of secondary school completion of female increases from 42.5 to 74.0%. Our results from Local indicator of spatial autocorrelation (LISA) cluster maps show that 7 countries (mainly in West/Central Africa) formed the high-high clusters (hotspots for U5M) and may not achieve the SDG target 3.2 unless urgent and appropriate investments are deployed. As 2030 approaches, there is a need to address the problem of limited access to quality health care, female illiteracy, limited access to safe water, and poor access to quality family planning services, particularly across many sub-Saharan African countries.

A Longitudinal Multilevel Analysis of the Effects of Contraceptive Failures on Unintended Pregnancies among Women in Urban Nigeria.

Unintended pregnancy is a global public health concern. However, the effect of contraceptive failure on unintended pregnancy remains unclear in Nigeria. We undertook a longitudinal analysis to examine the effect of contraceptive failure on unintended pregnancy among urban women in Nigeria. We used panel data from the Nigerian Urban Reproductive Health Initiative. The Measurement, Learning and Evaluation program conducted the surveys among a cohort of women aged 15-49 who were first interviewed at baseline in 2010/2011 and followed up at endline in 2014/2015. Analytic sample was 4140 women aged 15-49 who ever used contraceptives. We fitted three-level multilevel binary logistic regression models estimated with GLLAMM. The study established evidence that there is a significant effect of contraceptive failure on unintended pregnancy among urban women in Nigeria. The positive effect of between-person contraceptive failure indicates that respondents who experienced more contraceptive failure than the average in the sample had 5.26 times higher odds of unintended pregnancy (OR = 5.26; p-value < 0.001). Results also established a significant effect of within-person contraceptive failures among the respondents. Findings suggest there is evidence of a significant longitudinal effect of contraceptive failure on unintended pregnancy in urban Nigeria. Efforts to reduce unintended pregnancy must include interventions to address the problem of contraceptive failure among urban women in Nigeria.

Comparing the reasons for contraceptive discontinuation between parenting adolescents and young women in sub-Saharan Africa: a multilevel analysis.

BACKGROUND: Adolescent sexual and reproductive health remains a major public health and development issue of global importance. Given that adolescents and young people are heterogenous groups in terms of many characteristics, this study expands the literature by comparing the reasons for contraceptive discontinuation between parenting adolescents (aged 15-19) and parenting young women (aged 20-24) in sub-Saharan Africa (SSA). METHODS: Data for the study came from Demographic and Health Surveys of 22 SSA countries. The outcome variable was reasons for discontinuation. We performed multilevel binary logistic regression on analytic samples comprising 1485 parenting adolescents and 10,287 parenting young women across the selected SSA countries. RESULTS: Findings show that the proportion of respondents who used modern contraceptives was lower among parenting adolescents (35%) relative to their 20-24-year-old counterparts (43%). Higher percentages of parenting adolescents than young women discontinued contraceptives because of reasons such as pregnancy or method failure (i.e., 9.9% and 8.17% accordingly), husband disapproval, access or availability issues, wanting more effective methods, and inconvenience in using methods. The multilevel analysis further highlighted disparities between parenting adolescents and parenting young women who discontinued contraceptives. For instance, parenting young women had 30% lower odds of discontinuing contraceptives due to pregnancy or method failure than parenting adolescents. CONCLUSION: The study established disparities in the reasons for contraceptive discontinuation between parenting adolescents and parenting young women, with adolescents demonstrating greater vulnerabilities and higher risks. Considerable attention must be given to parenting adolescents in the efforts to achieve equity goals such as the Sustainable Development Goals and universal health coverage in SSA.

The Relationship between Childcare-Giving Arrangements and Children's Malnutrition Status in South Africa.

Multiple caregiving arrangements have become common for childcare globally, and South Africa is no exception. Previous childcare studies mainly focused on the caregiver and household characteristics. Evidence on the influence of childcare on malnutrition is sparse. This study aimed to examine the relationship between exposure to secondary and multiple forms of care and child malnutrition, with a particular focus on child stunting and overweight among children. A cross-sectional study of a sample of 2966 dyads of mothers and children under five were analysed from the 2017 National Income Dynamics Study (NIDS) Wave 5. Descriptive and inferential statistics were used to analyse the data. The results indicated that 22.16% of the children were stunted and that 16.40% were overweight. Most children were mainly cared for at home (67.16%) during the day. Some results of the obtained multivariable analyses show that lack of being cared for in a crèche or school during the day was significantly associated with stunting (odds ratio (OR) 2; confidence interval (CI) 1.10-3.62, p < 0.05) and overweight (OR) 3.82; (CI) 1.60-9.08, p < 0.05). Furthermore, in this study, 69.88% of children who were cared for at home by the primary caregiver had no other forms of multiple care arrangements. The results showing high stunting and overweight rates among children cared for at home suggest that the government needs to look into supporting caregiver parenting. The high unemployment rates in the country highlight the importance of socioeconomic status in childcare and its implication for children's nutritional outcomes. The study's findings suggest the need for innovative strategies to address the challenges associated with multi-caregiving which negatively affects children's nutritional outcomes.

Understanding context in the implementation of emergency obstetric and neonatal care in health facilities in Osun State, Nigeria- a mixed-methods study.

BACKGROUND: Successful implementation of Emergency Obstetric and Neonatal Care (EmONC) is likely to improve pregnancy outcomes and is essential for quality maternity care. Context in implementation is described as factors that enabled or disabled implementation of interventions. While the context of implementation is important for the effectiveness of evidence-based interventions, the context of EmONC implementation has not been widely studied in Nigeria. METHODS: The research design was cross-sectional descriptive. A mixed-methods approach was used to assess and explore the context of implementing EmONC in referral centres in Osun state. A purposive sampling technique was used to select the three tertiary health facilities in Osun State and six secondary health facilities from the six administrative zones in the State. A total of 186 healthcare providers in these referral centres participated in the quantitative part of the study, and eighteen in-depth interviews were conducted for its qualitative aspect. An adapted questionnaire from Context Assessment Index and an interview guide were used to collect data. Quantitative data were analysed using descriptive and inferential statistics at 0.05 significance level, while qualitative data were analysed using the thematic approach. RESULTS: The percentage mean score of context strength in EmONC implementation was 63% ± 10.46 in secondary and 68% ± 10.47 in tertiary health facilities. There was a significant difference in the leadership (F (1, 184) = 8.35, p < 0.01), evaluation (F (1, 184) = 5.35, p = 0.02) and overall context (F (1, 184) = 6.46, p = 0.01) of EmONC implementation in secondary and tertiary health facilities. Emerging themes in EmONC context were: Resources for EmONC implementation; Demand for EmONC; Efficiency of funding; Institutional leadership; and Performance evaluation. CONCLUSIONS: The context of EmONC implementation in the referral health facilities was generally weak. The secondary health facilities' weaknesses were worse compared to the tertiary health facilities. The five key contextual factors could inform strategies for improving EmONC implementation in health facilities to ensure improved access to care that will reduce deaths from obstetric complications in Nigeria.

Exploring barriers and facilitators to integrated policy formulation and implementation of family planning and urban development programmes in Nigeria.

BACKGROUND: As more people now live in urban areas than in rural communities in Nigeria, urban development (UD) requires urgent policy and programmatic attention. Although the population factor has been identified as important to achieving national development goals, and evidence suggests that meeting the family planning (FP) and reproductive health (RH) needs of the vulnerable urban population can serve as an important recipe for achieving population growth rates consistent with building sustainable, habitable and prosperous urban settings, FP remains a neglected subject in UD initiatives in Nigeria. This study explored barriers and facilitators in achieving integrated policy formulation and implementation of FP and UD programmes in Nigeria. METHODS: We conducted key informant interviews (n = 37) with relevant FP/RH and UD stakeholders in Ibadan and Kaduna-two megacities that have undergone several UD and FP intervention programmes in the south and north of Nigeria. The sample size was determined by data saturation. Data were organized using ATLAS.ti and NVivo 12 software, and analysis was conducted using a thematic approach. RESULTS: We found that relevant government agencies largely work in silos. Other identified barriers to integrated policy formulation/implementation of FP and UD programmes in Nigeria include lack of knowledge about the FP-UD nexus between professionals, ineffective implementation and monitoring of existing guidelines, lack of policy documentation that clearly links FP and UD, and frequent transfer of government stakeholders. Notwithstanding the identified barriers, the study established ways of achieving synergy between FP and UD sectors, including stakeholder engagement, intersectoral collaborations, sensitization and publicity, roundtable discussion, interdisciplinary research, conferences and other interactive and knowledge-sharing fora. CONCLUSIONS: We conclude that addressing barriers to the intersectoral linkage between FP and UD is fundamental to achieving sustainable urbanization in Nigeria.

Assessing Community Acceptance of Maternal Immunisation in Rural KwaZulu-Natal, South Africa: A Qualitative Investigation.

Despite the significant benefits of maternal immunisation, uptake remains low in many parts of the world. In this qualitative study, we aimed to assess the factors that influence pregnant women's decision to engage with maternal immunisation in rural KwaZulu-Natal, South Africa. We conducted in-depth interviews with a total of 28 purposively sampled pregnant women and key informants using semi-structured topic guides. Data analysis was conducted using a modified Health Belief Model framework that included constructs of barriers to action, modifying factors of cue to action and perceived social norms. The findings show that traditional customs and institutional barriers such as low-quality health service delivery, long queues, and distance to the health facilities, immunisation vaccine stockouts and low levels of maternal knowledge influence the choice and decision to engage with maternal immunisation. Understanding health-related behaviours and addressing barriers to care is important in facilitating vaccination uptake. This study contributes to the understanding of maternal immunisation uptake in low-resource settings.

Comparing the timeliness and adequacy of antenatal care uptake between women who married as child brides and adult brides in 20 sub-Saharan African countries.

CONTEXT: Considering the persistent poor maternal and child health outcomes in sub-Saharan Africa (SSA), this study undertook a comparative analysis of the timing and adequacy of antenatal care uptake between women (aged 20-24 years) who married before age 18 and those who married at age 18 or above. METHOD: Data came from Demographic and Health Surveys of 20 SSA countries. We performed binary logistic regression analysis on pooled data of women aged 20-24 (n = 33,630). RESULTS: Overall, the percentage of child brides in selected countries was 57.1%, with the lowest prevalence found in Rwanda (19.1%) and the highest rate in Chad (80.9%). Central and West African countries had the highest prevalence of child marriage compared to other sub-regions. Bivariate results indicate that a lower proportion of child brides (50.0%) had 4+ ANC visits compared to the adult brides (60.9%) and a lower percentage of them (34.0%) initiated ANC visits early compared to the adult brides (37.5%). After controlling for country of residence and selected socio-economic and demographic characteristics, multivariable results established significantly lower odds of having an adequate/prescribed number of ANC visits among women who married before age 15 (OR: 0.63, CI: 0.57-0.67, p<0.001), and women who married at ages 15-17 (OR: 0.81, CI: 0.75-0.84, p<0.001) compared to those who married at age 18+. Similar results were established between age at first marriage and timing of first ANC visit. Other interesting results emerged that young women who married earlier than age 18 and those who married at age 18+ differ significantly by several socio-economic and demographic characteristics. CONCLUSION: Efforts to improve maternal and child health outcomes in SSA must give attention to address the underutilization and late start of antenatal care uptake among child brides.

Influence of child marriage on institutional delivery and high-risk births among young women in 31 sub-Saharan African countries.

While child marriage persists in sub-Saharan Africa (SSA), little is known about its influence on institutional delivery/high-risk births (IDHRB). We analyzed pooled data on young women aged 15-24 (N = 113,588) from the most recent Demographic and Health Surveys of 31 SSA countries to examine the influence of child marriage on IDHRB. Binary logistic regression analysis was done to explore statistically significant relationships. Findings showed that unskilled delivery was significantly higher among women who married before age 15 (67.2%) and at ages 16-17 (48.2%) compared to those who married at age 18+ (30.2%). The prevalence of high-risk birth was higher among women who married before age 15 (97.2%) and at ages 16-17 (80.8%) compared to those who married at 18+ (48.4%). Inferential analysis showed that respondents who married before age 15 and at ages 16-17, respectively, had five-fold and two-fold higher odds of experiencing unskilled delivery compared to those who married at age 18 +. Odds of having high-risk births were significantly higher among child-brides compared to those who had first marriage as adults. This study concludes that policies/programs that would successfully delay first marriage among women must be pursued to reduce high-risk births and unskilled delivery in SSA.

Trends and correlates of girl-child marriage in 11 West African countries: evidence from recent Demographic and Health Surveys.

Background: West Africa historically has a high prevalence of girl-child marriage and requires substantial reduction to meet the United Nation's Sustainable Development Goals (SDG) target of ending child marriage by 2030, but current data on progress is sparce. We aimed to determine the trend in child marriage in West Africa and assess the influence of selected socio-demographic factors. Methods: We analysed data on women aged 18-24 years from the two most recent Demographic and Health Surveys (conducted between 2006 and 2014) for 11 West African countries to determine the prevalence and trend of girl-child marriage. Multivariable logistic regression analysis was used to assess the relationship between girl-child marriage and selected socio-demographic factors. Results: The prevalence of child marriage in West Africa is 41.5%. An overall decrease of 4.6% (annual rate of 0.01%) was recorded over a seven-year inter-survey period. Three countries (Cote d'Ivoire, Nigeria, and Niger) recorded increased prevalence while the rate was unchanged in Burkina Faso, and the other six countries had reduced prevalence between the last two surveys. Sierra Leone recorded the highest decrease in prevalence (22%) and an annual reduction rate of 0.04%; Cote d'Ivore had the highest increase (65.3%). In virtually all countries, rural residence, low education, poor household economic status and non-Christian religious affiliation were significantly associated with higher odds of girl-child marriage. Conclusions: The prevalence of girl-child marriage remains high in West Africa and the trend shows very slow progress. While substantial inter-country variations exist in overall rate and trend of child marriage, the rate of progress is inadequate across all countries.

Approaches, achievements, challenges, and lessons learned in setting up an urban-based Health and Demographic Surveillance System in South Africa.

Reliable civil registration and vital statistics (CRVSs) are essential for estimating mortality rates and population changes, and are critical for public health and socio-economic planning. CRVSs are largely incomplete in Africa, thus Health and Demographic Surveillance Systems (HDSSs) fill gaps in CRVSs, albeit existing HDSSs in South Africa are in rural areas. This limits the generalisability of such data in a country such as South Africa where over 60% live in urban areas, and where there are limitations to access health and social services. We describe the approaches, achievements, challenges and lessons learned in setting up a HDSS site in Soweto and Thembelihle (SaT-HDSS), Johannesburg; which is the first urban-based HDSS in Southern Africa. We also highlight a number of studies being implemented in the HDSS. In 2017-2020, the HDSS has enrolled 124,169 individuals and followed up 95% of this population through 3 rounds of data collection. Several challenges were encountered during the initiation of the HDSS, including difficulties in community mobilisation and entry, stakeholders' engagement and participation, inaccessibility problems and concerns about safety of fieldworkers, and difficulty in getting/recruiting technical staff with requisite experience. Nevertheless, the SaT-HDSS was successfully established through application of several strategies, including continuous community engagement and stakeholders' mobilisation; in-depth training and retraining of all study staff; technical support from well-established HDSS sites across Africa, and international academic collaborations. Despite the challenges of undertaking routine surveillance of a hard-to-reach and highly mobile population, the SaT-HDSS was successfully established with a high-retention rate. The HDSS offers an important lens on morbidity and mortality and serves as a platform for pilots of interventions and programmes aimed at improving health and well-being of an urban population.

Knowledge and attitudes towards maternal immunization: perspectives from pregnant and non-pregnant mothers, their partners, mothers, healthcare providers, community and leaders in a selected urban setting in South Africa.

BACKGROUND: Maternal immunization has prevented millions of child deaths globally; nevertheless, incomplete vaccination remains a public health concern in South Africa, where almost half of child deaths occur during neonatal period. This study explored the knowledge and attitudes inhibiting vaccine acceptancy during pregnancy. METHODS: Key informant and semi-structured interviews were conducted with pregnant women receiving antenatal care at community clinics, antenatal care staff, women enrolled in maternal immunization trials, community leaders and non-pregnant women residing in Soweto. Focus Group Discussions were also held with the mothers and husbands/partners of the pregnant women (n = 55). RESULTS: The study established good knowledge, a positive attitude and high acceptability of maternal immunization among pregnant women, non-pregnant women, antenatal staff as well as church and community leaders. Men were the least positive about maternal immunization. Aside from antenatal staff, there was poor knowledge regarding the types of vaccinations administered and the health benefits of immunization across all the study groups. Reasons adduced for poor knowledge about the types of vaccinations include lack of communication on maternal immunization during antenatal sessions or clinic visits and power dynamics that tend to exist between healthcare workers and patients. CONCLUSION: Ensuring that healthcare workers provide useful information on immunization during antenatal visits as well as include men in education sessions regarding the benefit of vaccination may increase patients' confidence and immunization uptake.

Disparities in pregnancy-related deaths: spatial and Bayesian network analyses of maternal mortality ratio in 54 African countries.

BACKGROUND: Maternal mortality remains a public health problem despite several global efforts. Globally, about 830 women die of pregnancy-related death per day, with more than two-third of these cases occurring in Africa. We examined the spatial distribution of maternal mortality in Africa and explored the influence of SDoH on the spatial distribution. METHODS: We used country-level secondary data of 54 African countries collected between 2006 and 2018 from three databases namely, World Development Indicator, WHO's Global Health Observatory Data and Human Development Report. We performed descriptive analyses, presented in tables and maps. The spatial analysis involved local indicator of spatial autocorrelation maps and spatial regression. Finally, we built Bayesian networks to determine and show the strength of social determinants associated with maternal mortality. RESULTS: We found that the average prevalence of maternal mortality ratio (MMR) in Africa was 415 per 100 000 live births. Findings from the spatial analyses showed clusters (hotspots) of MMR with seven countries (Guinea-Bissau, Guinea, Sierra Leone, Cote d'Ivoire, Chad and Cameroon, Mauritania), all within the Middle and West Africa. On the other hand, the cold spot clusters were formed by two countries; South Africa and Namibia; eight countries (Algeria, Tunisia, Libya, Ghana, Gabon and Congo, Equatorial Guinea and Cape Verde) formed low-high clusters; thus, indicating that these countries have significantly low MMR but within the neighbourhood of countries with significantly high MMR. The findings from the regression and Bayesian network analysis showed that gender inequities and the proportion of skilled birth attendant are strongest social determinants that drive the variations in maternal mortality across Africa. CONCLUSION: Maternal mortality is very high in Africa especially in countries in the middle and western African subregions. To achieve the target 3.1 of the sustainable development goal on maternal health, there is a need to design effective strategies that will address gender inequalities and the shortage of health professionals.

Changes in contraceptive and sexual behaviours among unmarried young people in Nigeria: Evidence from nationally representative surveys.

CONTEXT: Nigeria is a high-burden country in terms of young people's health. Understanding changes in young people's sexual and reproductive health (SRH) behaviours and the associated factors is important for framing appropriate interventions. OBJECTIVE: This study assessed changes in SRH behaviours of unmarried young people aged 15-24 and associated factors over a ten-year period in Nigeria. DATA AND METHOD: We analysed datasets from Nigeria Demographic and Health Surveys of 2008, 2013 and 2018 to assess changes in inconsistent condom use, non-use of modern contraceptives; multiple sexual partnership; and early sexual debut. Using binary logistic regression, we assessed the association of selected variables with the SRH behaviours. RESULTS: Over four-fifths of unmarried young people (15-24) in Nigeria engaged in at least one risky sexual behaviour in each survey year. The pattern of changes in the four risky SRH behaviours was consistent over the 10-year period, with the highest rates of each behaviour occurring in 2018 while the lowest rates were in 2013, thus indicating an increase in the proportion of respondents engaging in risky sexual behaviours over the study period. Comprehensive HIV/AIDS knowledge, male gender, older age category (20-24), residence in south-west Nigeria, urban residence, higher socio-economic status, secondary/higher education were mostly protective against the four SRH variables analysed across the different data waves. CONCLUSION: Addressing the high and increasing level of risky SRH behaviours among young people in Nigeria is imperative to improve overall national health status and to ensure progress towards achieving SDG target 3.7 focusing on SRH.

Community perspectives and caregivers' healthcare practices and responses to the four major childhood killer diseases in Nigeria.

Two-thirds of Nigeria's childhood deaths is attributable to four preventable/curable diseases-diarrhoea, malaria, meningitis and pneumonia (DMMP). Community perspectives and caregivers' practices about these child-killer diseases are poorly documented. Drawing on individual and group interviews (n=259), we explored community members' perspectives, and caregivers' practices/responses regarding DMMP among children across Nigeria's three major ethnic groups. Using deductive reasoning and data analysis in Atlas.ti, results from the narratives formed four thematic issues-respondents' perception and knowledge about the causes of the diseases; perception and knowledge about prevention; perception and knowledge of symptoms and fatality of the diseases; and caregivers' practices regarding the prevention and management of the diseases. Results demonstrate significant misconception about the aetiology of pneumonia and meningitis. We found ostensible disconnection between knowledge and practice. Interventions including health education programmes/sensitizations on the causes, prevention/management of DMMP are necessary to achieve reduction in the burden of childhood mortality in Nigeria.

Death registration in Nigeria: a systematic literature review of its performance and challenges.

BACKGROUND: Death registration provides an opportunity for the legal documentation of death of persons. Documentation of deaths has several implications including its use in the recovery of inheritance and insurance benefits. It is also an important input for construction of life tables which are crucial for national planning. However, the registration of deaths is poor in several countries including Nigeria. OBJECTIVE: This paper describes the performance of death registration in Nigeria and factors that may affect its performance. METHODS: We conducted a systematic literature review of death registration completeness in Nigeria to identify, characterize issues as well as challenges associated with realizing completeness in death registration. RESULTS: Only 13.5% of deaths in Nigeria were registered in 2007 which regressed to 10% in 2017. There was no data reported for Nigeria in the World Health Organization database between 2008 and 2017. The country scored less than 0.1 (out of a maximum of 1) on the Vital Statistics Performance Index. There are multiple institutions with parallel constitutional and legal responsibilities for death registration in Nigeria including the National Population Commission, National Identity Management Commission and Local Government Authorities, which may be contributing to its overall poor performance. CONCLUSIONS: We offer proposals to substantially improve death registration completeness in Nigeria including the streamlining and merger of the National Population Commission and the National Identity Management Commission into one commission, the revision of the legal mandate of the new agency to mainly coordination and establishment of standards. We recommend that Local Government authorities maintain the local registries given their proximity to households. This arrangement will be enhanced by increased utilization of information and communications technology in Civil Registration and Vital Statistics processes that ensure records are properly archived.

Ethnicity, religious affiliation and girl-child marriage: a cross-sectional study of nationally representative sample of female adolescents in Nigeria.

BACKGROUND: The persistently high prevalence of girl-child marriage remains a public health and developmental concern in Nigeria. Despite global campaign against the practice and policy efforts by Nigerian government, the prevalence remains unabated. This study investigates the prevalence and the influence of ethnicity and religious affiliation on the girl-child marriage among female adolescents in Nigeria. METHODS: Data of 7804 girls aged 15-19 years extracted from the 2013 Nigeria Demographic and Health Survey were used. Ethnic groups were classified into five: major Northern ethnic group (Hausa/Fulani); Northern ethnic minorities; two major Southern ethnic groups (Yoruba and Igbo), and Southern ethnic minorities. The prevalence of girl-child marriage was determined for the five ethnic groups and individually for each ethnic minority group. Relationships between ethnicity and religious affiliation on girl-child marriage were explored using Cox proportional hazard regression models, adjusting for residence, education and wealth quintile. RESULTS: Child marriage was higher for the Northern majority ethnic group of Hausa/Fulani (54.8%) compared to the two major Southern ethnic groups (3.0-3.6%) and aggregated Northern ethnic minorities (25.7%) and Southern minorities (5.9%). However, overall, the less known Northern ethnic minority groups of Kambari (74.9%) and Fulfude (73.8%) recorded the highest prevalence. Compared to the major Southern ethnic group of Yoruba, the adjusted hazard ratio (AHR) of child marriage was significantly higher for Northern ethnic minorities (AHR = 2.50; 95% C.I. = 1.59-3.95) and Northern major ethnicity (AHR = 3.67, 95% C.I. = 2.33-5.77). No significant difference was recorded among Southern ethnic groups. Girls affiliated to other religions (Muslim and traditionalist) had higher child-marriage risks compared to Christians (AHR = 2.10; 95% C.I. = 1.54-2.86). CONCLUSION: Ethnicity and religion have independent associations with girl-child marriage in Nigeria; interventions must address culturally-laden social norms that vary by ethnic groups as well as religious-related beliefs.

Regional variations in the use of postnatal care in Nigeria: a spatial analysis.

Maternal health outcomes vary considerably in Nigeria, with maternal mortality ratio ranging from 165 per 100,000 live births in the South-west to 1549 per 100,000 live births in the North-east. One important maternal health indicator is an adequate use of postnatal care (PNC); however, the evidence is sparse on its spatial distribution across regions in Nigeria. This paper thus examined the spatial distribution of uptake of postnatal care in Nigeria using data from the 2013 Nigeria Demographic and Health Survey, with a sample of 12,127 women aged 15-49 years. The Bayesian-structured additive regression of the logit model was used to examine the spatial relationships. The results revealed a north-south divide in the use of postnatal care, with higher PNC uptake established in the latter. Interestingly, results showed significant intra-region residual spatial variations with higher PNC use in Yobe and Bauchi in North-east Nigeria compared to other states within the region. The findings indicate the need for policymakers to develop state- and region-specific health policy and intervention programs to address the inequity in postnatal care coverage and usage across regions in Nigeria.

Child's Risk Attributes at Birth and Infant Mortality Disparities in Nigeria.

Births in avoidable high-risk contexts defined by the interplay of sub-optimal childbearing age, short spacing, and first and high birth order incur elevated risks of childhood death. However, the extent of disparities in risks of dying in infancy vis-à-vis the continuum of non-high-risk and (un)avoidable high-risk attributes at birth as determined by mother's age at childbirth, child spacing, and birth order characteristics is yet to be adequately explored in Nigeria as elsewhere. To fill this gap, chi-square association test and Cox's proportional hazards regression were used to analyze data of 31,260 nationally representative children aged 0-59 months drawn from 2013 Nigeria Demographic and Health Survey. Disparities in infant mortality risks were mainly examined across the spectrum of birth-related risk attributes at birth broadly categorized as no extra high-risk, unavoidable first- order risk and combined avoidable high-risk. The risks of dying in infancy differed significantly by risk attributes to the extent dictated by other confounders. Also, infant mortality risks varied significantly by all moderating factors excluding religion, water source, toilet type and place of delivery. Interventions targeted at reducing avoidable high-risk fertility rate and strengthening health system to provide life-saving care to most-at-risk children would engender rapid improvement in infant survival.

Health and Demographic Surveillance Systems Within the Child Health and Mortality Prevention Surveillance Network.

Health and demographic surveillance systems (HDSSs) provide a foundation for characterizing and defining priorities and strategies for improving population health. The Child Health and Mortality Prevention Surveillance (CHAMPS) project aims to inform policy to prevent child deaths through generating causes of death from surveillance data combined with innovative diagnostic and laboratory methods. Six of the 7 sites that constitute the CHAMPS network have active HDSSs: Mozambique, Mali, Ethiopia, Kenya, Bangladesh, and South Africa; the seventh, in Sierra Leone, is in the early planning stages. This article describes the network of CHAMPS HDSSs and their role in the CHAMPS project. To generate actionable health and demographic data to prevent child deaths, the network depends on reliable demographic surveillance, and the HDSSs play this crucial role.
