摘要:Rationale. Nearly half of all deaths prior to the age of five years globally occur in five nations: China, Democratic Republic of the Congo, India, Nigeria, and Pakistan, with almost a third of these deaths in India and Nigeria (Lawson et al., 2014). Methods. This study investigated the cultural beliefs about infant mortality among working mothers in Nigeria. A multistage sampling technique was used to sample (N = 2400) working mothers on their cultural beliefs in relation to infant mortality. The present study uses an indigenous questionnaire, “Cultural Beliefs of Infant Mortality Questionnaire (CBIMQ).” A series of hierarchical regressions and analysis of covariance (ANCOVA) were employed to test the hypotheses that cultural beliefs about infant mortality would vary by geography, ethnicity, age, income, education, and marital status. Results. Findings revealed that age, education, and mothers’ monthly income significantly predicted working mothers’ cultural beliefs of infant mortality. Furthermore, results showed differences in marital status, urban vs. rural locality, ethnicity, and religious affiliation on working mothers’ cultural beliefs of infant mortality. Conclusion. We discuss the implications to address health issues and provide recommendations for targeted programs such as seminars and workshops to be organized by counselors on the scientific causes of infant mortality.
