The problem
Intervention: None - this is an observational study examining child marriage as a risk factor
Who it was tested with: Currently married women in India (N=421,107) from the National Family and Health Survey 4 (2015-2016).
Experience from people who deliver programmes: stories, case studies and lessons learned. Valuable for understanding how and why, and for spotting what to test next, but not a measure of effect.
"We utilize biomarkers and self-reported data from the nationally representative National Family and Health Survey 4 (2015-2016) to examine the associations between child marriage and hypertension, diabetes, heart disease, asthma and thyroid disorder among currently married women (N = 421 107). We use regression models adjusted for a range of demographic and socio-economic controls to assess the association between child marriage and NCDs among women in India." This is a large-scale cross-sectional analysis with rigorous adjustment for confounders, providing strong observational evidence of an association between child marriage and NCDs.
Cross-sectional design prevents causal inference. Self-reported health outcomes may be subject to recall bias. The study cannot determine whether child marriage directly causes NCDs or whether unmeasured confounders explain the associations.
