This study analyzed data from Demographic and Health Surveys in India, Bangladesh, Nepal, and Pakistan to assess the association between child marriage and reproductive health outcomes. The results showed that child marriage was significantly associated with several negative fertility and fertility control outcomes. Women married in early adolescence (under age 15) generally experienced more negative outcomes than those married in middle adolescence (ages 15-17). These included higher rates of early fertility, unwanted pregnancies, lack of fertility control, and low lifetime fertility control. While informative, the study had some limitations such as possible self-reporting bias and an inability to establish causal relationships with the cross-sectional data.
