This study examines the relationship between maternal household decision-making autonomy and children’s nutritional status using data from 2011 Bangladesh Demographic and Health Survey. The analyses are restricted to 2056 currently married, nonpregnant women aged 15 to 49 years who had at least 1 birth 5 years preceding the survey. Theoretically relevant predictors of children’s nutritional status including maternal autonomy are analyzed to identify factors significantly associated with children’s nutritional status using stepwise logistic regression. Results indicate that 34.8% children are stunted, 16.1% are wasted, and 45.9% children are underweight. Children whose mothers participated in making all household decisions are 15%, 16%, and 32% significantly less likely to be stunted (odds ratio = 0.85; 95% CI = 0.67-0.98), underweight (odds ratio = 0.84; 95% CI = 0.70-0.98), and wasted (odds ratio = 0.68; 95% CI = 0.52-0.90), respectively, than mothers who did not participate in making any decision. Increasing maternal decision-making autonomy may reduce the prevalence of malnourished children as well as contribute to have a healthier future generation.
