Child marriage and its impact on fertility and fertility-related outcomes in South Asian countries

Although South Asia (SA) is reported as a home of child marriage, the association of child marriage with fertility and fertility-related outcomes in this region is poorly explored. The most recent data of the Demographic and Health Survey of six SA countries - Afghanistan, Bangladesh, India, Maldives, Nepal and Pakistan - have been used in this article. The unit of analysis is 584,213 currently married women aged 20-49. The outcomes of interest are fertility and fertility-outcomes. Quantitatively important and reliable estimates were obtained from the statistical analyses. The results are presented by odds ratios with 95% CIs. Findings reveal that, overall, 42.1% of the respondents were married-off before age 18. The prevalence of child marriage was lowest in the Maldives and highest in Bangladesh at 20.5% and 74.4% respectively. The likelihood of early childbirth and repeated childbirth were significantly (p < 0.001) lower and that for high fertility, unintended pregnancy, lifetime pregnancy termination and use of a modern contraceptive method was significantly higher in the child married women compared to their adult married counterparts. Reforms should aim to have more girls remain in schooling for both personal and overall societal development and also to reduce adverse reproductive outcomes caused by child marriage.
