Maternal education and child immunization: the mediating roles of maternal literacy and socioeconomic status.

INTRODUCTION: Previous studies in Nigeria have documented significant association between maternal education and child immunization. However, little is known about the pathway through which maternal education improves immunization uptake. This study aims to examine whether maternal literacy and socioeconomic status mediates the relationship between maternal education and complete immunization coverage in children. METHODS: Nationally representative data from the first wave of the Nigeria General Household Survey-Panel were used, which includes 661 children aged one year and below. Regression analyses were used to model the association between maternal education and child's immunization uptake; we then examined whether maternal literacy and household economic status mediates this association. RESULTS: Of the 661 children, 40% had complete immunization. The prevalence ratio (PR) of complete immunization in children whose mothers were educated versus those whose mothers were not educated was 1.44 (95% CI: 1.16-1.77). Maternal literacy substantially reduced the estimated association between maternal education and complete immunization by 90%, whereas household economic status reduced the estimates by 27%. CONCLUSION: These findings suggest that complete immunization was higher in children whose mothers were educated, partly because maternal education leads to acquisition of literacy skills and better health-seeking behavior which then improves immunization uptake for their children. Socioeconomic status is an alternative pathway but with less substantial indirect effect.

Gender difference in the prevalence and socio-demographic correlates of mobility disability among older adults in Nigeria.

The aim of the current study is to examine gender differences in mobility disability among older people in Nigeria, and to explore factors associated with gender differences in mobility disability in later life. Data were used from the first (2010-2011) wave of the Nigeria General Household Survey-Panel, which included 3586 respondents aged 50 years and above. Mobility disability was assessed as self-reported difficulty in walking 100 m, walking 1 km, walking uphill, running, bending or stooping, and climbing stairs. Regression analyses were used to estimate the extent to which socio-demographic conditions contribute to gender differences in mobility disability. We observed a higher prevalence of mobility disability among women compared to men (20.1 vs. 12.5 %, P < 0.001). The prevalence ratios (PR) of mobility disability for women versus men was 1.61 (95 % CI 1.38-1.88, P < 0.001); after adjusting for age, marital status, place of residence, self-reported health status and cognitive difficulties, the PR was 1.55 (95 % CI 1.30-1.85, P < 0.001). In the fully adjusted model, mobility disability still remained significantly higher among women (PR 1.60, 95 % CI 1.32-1.93, P < 0.001). The marginal effects of socio-demographic and health factors were stronger for women than for men. Socio-demographic and health variables considered in this study explained between 19.3 % (men) and 22.3 % (women) of variance in mobility disability suggesting that additional factors beyond those considered in this study warrant further investigation, so that differences in mobility disability between older men and women in Nigeria can be fully understood.
