Abstract: BACKGROUND:Obesity is a major health problem in low and middle income countries (LMICs) and is associated with miscarriage. This study aims to examine the association between obesity and miscarriage among reproductive age women (15-49 years) in Nepal. METHODS:The combined 19160 cross-sectional pregnancy data from the Nepal Demographic and Health Survey (NDHS) for the years 2001, 2006, 2011 and 2016 was utilized. Miscarriage was defined as a spontaneous loss of pregnancy that occurred before the foetus reached 7 months of gestational age. Logistic regression analyses that adjusted for clustering, stratification and sampling weights were used to examine the association between obesity and miscarriage among women of reproductive age. RESULTS:The odds of miscarriage were 1.45 times higher (Adjusted odds ratio (AOR) = ?1.45; 95%Cl: 1.06, 1.98, P = 0.021) among women with obesity. Women who did not use contraception, younger (15-19 years), and older women (35 years or more) were significantly more likely to have miscarriage. Women who smoked tobacco reported higher odds of miscarriage than women who did not smoke tobacco (AOR = ?1.27; 95%Cl: 1.07,1.50, P = 0.006). Stratification of maternal smoking status by maternal Body Mass Index (BMI), after adjusting for contraception, mother age and year of survey revealed that tobacco smoking and obesity are associated with miscarriage (AOR = ?1.46; 95%Cl: 1.05,2.04, P = 0.025). CONCLUSIONS:Findings from this study show that obesity and tobacco smoking are associated with miscarriage. Smoking cessation, pregnancy planning and counselling on healthy weight for women of reproductive age in Nepal may help promote healthy behaviours and decrease the likelihood of miscarriage.
