REGIONAL VARIATIONS IN INFANT AND CHILD MORTALITY IN NIGERIA: A MULTILEVEL ANALYSIS

Summary There are substantial regional disparities in under-five mortality in Nigeria, and evidence suggests that both individual- and community-level characteristics have an influence on health outcomes. Using 2008 Nigeria Demographic and Health Survey data, this study (1) examines the effects of individual- and community-level characteristics on infant/child mortality in Nigeria and (2) determines the extent to which characteristics at these levels influence regional variations in infant/child mortality in the country. Multilevel Cox proportional hazard analysis was performed on a nationally representative sample of 28,647 children nested within 18,028 mothers of reproductive age, who were also nested within 886 communities. The results indicate that community-level variables (such as region, place of residence, community infrastructure, community hospital delivery and community poverty level) and individual-level factors (including childs sex, birth order, birth interval, maternal education, maternal age and wealth index) are important determinants of infant/child mortality in Nigeria. For instance, the results show a lower risk of death in infancy for children of mothers residing in communities with a high proportion of hospital delivery (HR: 0.70, p<0.05) and for children whose mothers had secondary or higher education (HR: 0.84, p<0.05). Although community factors appear to influence the association between individual-level factors and death during infancy and childhood, the findings consistently indicate that community-level characteristics are more important in explaining regional variations in child mortality, while individual-level factors are more important for regional variations in infant mortality. The results of this study underscore the need to look beyond the influence of individual-level factors in addressing regional variations in infant and child mortality in Nigeria.

HIV/AIDS stigma and utilization of voluntary counselling and testing in Nigeria

BackgroundDespite the recognition of stigma as a hindrance to public health treatment and prevention there are gaps in evidence on the relationship between HIV stigma and VCT services utilization in Nigeria. The purpose of this study was to examine a community’s perceptions, feelings and attitudes towards people living with HIV/AIDS and how this is associated with access to utilization of voluntary counselling and treatment in Nigeria.MethodsA cross-sectional random study of Nigerians, using a mixed-method approach was carried out in two distinct ethnic areas of the country. Both quantitative and qualitative methods (mixed-methods) were used to collect data in Osun State (Yoruba ethnic group) in the South-West and Imo State (Igbo ethnic group) in the South East. Multivariate logistic regression was the model used to examine the association of interest.ResultsIt is shown that Nigerian public attitudes to HIV/AIDS and those infected with the disease are negative. The markers for stigma on the overall stigma index are significant predictors of utilization of voluntary counselling and testing. As the sum of negative feelings increases, there is less likelihood to using voluntary counselling and testing (VCT) and vice versa.ConclusionsCurrent national efforts at addressing the AIDS pandemic can only be successful when the issue of AIDS is de-stigmatized and is made a critical part of those efforts. One way to do this is through well-designed messages that should be posted in the media, community halls, health centers and other public places aimed at humanizing the disease and those affected and infected by it.

Barriers to accessing health care in Nigeria: implications for child survival

Background Existing studies indicate that about one in every six children dies before age five in Nigeria. While evidence suggests that improved access to adequate health care holds great potential for improved child survival, previous studies indicate that there are substantial barriers to accessing health care in Nigeria. There has not been a systematic attempt to examine the effects of barriers to health care on under-five mortality in Nigeria. This study is designed to address this knowledge gap. Data and method Data came from a nationally representative sample of 18,028 women (aged 15–49) who had a total of 28,647 live births within the 5 years preceding the 2008 Nigeria Demographic and Health Survey. The risk of death in children below age five was estimated using Cox proportional hazard models and results are presented as hazards ratios (HR) with 95% confidence intervals (CI). Results Results indicate higher under-five mortality risks for children whose mothers had cultural barriers and children whose mothers had resource-related barriers to health care (HR: 1.44, CI: 1.32–1.57, p<0.001), and those whose mothers had physical barriers (HR: 1.13, CI: 1.04–1.24, p<0.001), relative to children whose mothers reported no barriers. Barriers to health care remained an important predictor of child survival even after adjusting for the effects of possible confounders. Conclusion Findings of this study stressed the need for improved access to adequate health care in Nigeria through the elimination of barriers to access. This would enable the country to achieve a significant reduction in childhood mortality.Background Existing studies indicate that about one in every six children dies before age five in Nigeria.

Contextual Determinants of Maternal Health Care Service Utilization in Nigeria

Despite the high maternal mortality ratio in Nigeria, the use of maternal health care services is very poor. Attempts to explain this situation has focused on individual level factors and the influence of community contextual factors have not received much attention. This study examined the relation of community factors to the use of antenatal care in Nigeria, and explored whether community factors moderated the association between individual characteristics and antenatal care visits. Data were drawn from the 2008 Nigeria Demographic and Health Survey among 16,005 women aged 15–49 years who had had their last delivery in the five years preceding the survey. Results from multi-level models indicated that living in communities with a high proportion of women who delivered in a health facility was associated with four or more antenatal care visits. Residence in high-poverty communities decreased the likelihood of antenatal care attendance. Living in communities with a high proportion of educated women was not significantly related to antenatal care visits. Community factors acted as moderators of the association between educational attainment and antenatal care attendance. Improvement in antenatal care utilization may therefore be enhanced by targeting poverty reduction programs and increasing health facility delivery in disadvantaged communities.

Differential effect of wealth quintile on modern contraceptive use and fertility: evidence from Malawian women

BackgroundHigh fertility and wide inequality in wealth distribution are phenomenal problems in sub-Saharan Africa. Modern Contraceptives (MC) are useful for limiting fertility, but are not always easily accessible in Malawi. This study examines the gap in MC use and fertility between women in the richest and poorest Wealth Quintile (WQ).MethodsThe study was cross-sectional in design and utilized Malawi DHS dataset, 2010. It focused on women of reproductive age. The dependent variables are ever and current use of MC. Chi-square and multinomial logistic regression were used for the analysis.ResultsMean children ever born by women in the poorest and richest WQs were 3.94 ± 2.7 and 2.82 ± 2.3 respectively (p < 0.001). The adjusted total fertility rate (Adj.TFR) was higher among women in the poorest (Adj.TFR = 7.60) WQ than the richest (Adj.TFR = 4.45). The prevalence of ever use of MC was higher among women in the richest WQ (82.4%) than the poorest (66.8%) (p < 0.001). Similar pattern exists for current use of MC; 58.5% and 45.9% for women in the richest and poorest WQs respectively (p < 0.001). Women in the richest WQ were more likely to ever use (OR = 2.36; C.I = 2.07-2.69, p < 0.001) and currently using (OR = 1.66; C.I = 1.40-1.97, p < 0.001) MC than their counterparts in the poorest WQ. Slight reduction in odd-ratio of MC use among women in richest WQ resulted when socio-demographic variables were used as control.ConclusionFertility was higher and the use of MC was lower among women in the poorest than their counterparts in the richest WQ. Ensuring availability of MC at little or no cost may bridge the gap in contraceptive use between women in the poorest and richest WQ in Malawi.

Ethnic differentials in under-five mortality in Nigeria

Objective. There are huge regional disparities in under-five mortality in Nigeria. While a region within the country has as high as 222 under-five deaths per 1000 live births, the rate is as low as 89 per 1000 live births in another region. Nigeria is culturally diverse as there are more than 250 identifiable ethnic groups in the country; and various ethnic groups have different sociocultural values and practices which could influence child health outcome. Thus, the main objective of this study was to examine the ethnic differentials in under-five mortality in Nigeria. Design. The study utilized 2008 Nigeria Demographic and Health Survey (NDHS) data. We analyzed data from a nationally representative sample drawn from 33,385 women aged 15–49 that had a total of 104,808 live births within 1993–2008. In order to examine ethnic differentials in under-five mortality over a sufficiently long period of time, our analysis considered live births within 15 years preceding the 2008 NDHS. The risks of death in children below age five were estimated using Cox proportional regression analysis. Results were presented as hazard ratios (HR) with 95% confidence intervals (CI). Results. The study found substantial differentials in under-five mortality by ethnic affiliations. For instance, risks of death were significantly lower for children of the Yoruba tribes (HR: 0.39, CI: 0.37–0.42, p < 0.001), children of Igbo tribes (HR: 0.58, CI: 0.55–0.61, p < 0.001) and children of the minority ethnic groups (HR: 0.66, CI: 0.64–0.68, p < 0.001), compared to children of the Hausa/Fulani/Kanuri tribes. Besides, practices such as plural marriage, having higher-order births and too close births showed statistical significance for increased risks of under-five mortality (p < 0.05). Conclusion. The findings of this study stress the need to address the ethnic norms and practices that negatively impact on child health and survival among some ethnic groups in Nigeria.

The cost of being a man: social and health consequences of Igbo masculinity

In the bid to explain reproductive health outcomes in most developing countries, men have often been seen as the cause of the problem. However, no systematic attempt has been made to examine mens perception of their own social and health needs, including how ideologies of masculinity impact mens social and physical health. This study examines the Igbo context and shows how men understand and interpret masculinity and the consequences of this for social and health behaviours. Data from adolescent and adult Igbo men aged 15–75 were collected using both quantitative survey interviews (n = 1372) and qualitative techniques such as focus-group discussion (n = 20), in-depth interviews (n = 10) and key informant interviews (n = 10) in selected areas of south-eastern Nigeria. We collected data on gender role ideologies and sexuality issues and practices. Our analysis shows that there are social and health costs associated with adherence to masculine ideologies and a strong association between masculine ideologies and mens health, risk-taking and health-seeking behaviours in the study population. We conclude that all sexual and reproductive health programmes should include services that address the specific needs of men and those negative aspects of masculinity that tend to expose men to adverse health outcomes.

VARIATIONS IN UNMET NEED FOR CONTRACEPTION IN ZAMBIA: DOES ETHNICITY PLAY A ROLE?

Ethnicity has been found to be a significant indicator of social position, and many studies have also established that ethnicity is a significant determinant of contraceptive use. This study aims to examine whether ethnicity is an important predictor of unmet need for contraception. Analysis was based on data for 4343 ever-married women drawn from the 2007 Zambia Demographic and Health Survey. Descriptive analysis indicates that in all ethnic groups except the Barotse and Tonga, women aged 15-49 years were married at an average age below 18. The highest mean number of children among the ethnic groups was 6.7, among the Bemba; the lowest was 5.9, among the Barotse. The highest proportion of women with an unmet need for contraception resided in the Eastern region. Multivariate logistic analyses reveal that children ever-born and region of residence were the most important predictors of unmet need for spacing, whereas for unmet need for limiting predictors were age at first marriage and partners desire for children. Moreover, unmet need for spacing and limiting among women with secondary or higher education was significantly lower (47% and 50%, respectively) compared with those with no education. Ethnicity was not a significant predictor of unmet need for contraception. The findings stress the need for programmes aimed at enhancing the socioeconomic status of women.

Linkages between autonomy, poverty and contraceptive use in two sub-Saharan African countries

The paper presents the interaction effect of poverty-wealth status and autonomy on modern contraceptive use in Nigeria and Namibia with a view to examining whether poor women with less autonomy are less likely to use modern contraception than other women. A weighted sample of 3,451 currently married women in 2006-07 Namibia Demographic and Health Survey (DHS) and 23,578 in 2008 Nigeria (DHS) are used in the analysis. In Nigeria, the odd of using modern contraception is nearly 15 times higher among rich women with more autonomy than their counterparts who are poor and are less autonomous and 5.5 times higher among Namibian women. The study concluded that contraceptive behaviors of currently married women of Namibia and Nigeria are not independent of the linkage between poverty and autonomy and thus recommended that more concerted efforts be made in addressing poverty and improving the autonomous status of women in sub-Sahara Africa.

The relation of female circumcision to sexual behavior in Kenya and Nigeria

ABSTRACT One of the reasons for the perpetuation of female circumcision is that it controls female sexuality. In this study, the authors examined the relationship between female circumcision and the sexual behavior of women in Kenya and Nigeria. Data on women who were aware of circumcision and were circumcised were extracted from the Kenya Demographic and Health Survey of 2008–09 as well as the Nigeria Demographic and Health Survey of 2008. The sample size was 7,344 for Kenya and 16,294 for Nigeria. The outcome variables were age at first intercourse and total lifetime number of sexual partners. The study hypothesis was that women who were circumcised were less likely to have initiated sex early and to have only one sex partner. Cox proportional hazards regression and Poisson regression were used to examine the relations of female circumcision and other selected variables to sexual behavior. No association was observed between female circumcision and the outcomes for sexual behavior of women in Kenya and Nigeria. The argument of sexual chastity is insufficient to sustain the perpetuation of female circumcision.
