Summary
Written by AI, not yet AICS's view · claude-haiku-4-5-20251001This study examined whether maternal autonomy is associated with child stunting in Malawi using data from national surveys in 2010 and 2015/16. The researchers found that higher maternal autonomy was associated with reduced stunting, though this relationship appears to be mediated by other factors like maternal education and family wealth. Stunting prevalence decreased from 45% to 35% over the five-year period, while maternal autonomy improved during the same time. The analysis suggests that maternal autonomy alone does not directly prevent stunting, but works through its connection with education and economic factors.
Key points
- 39.2% of children in the pooled sample were stunted (height-for-age z-score < -2)
- Stunting prevalence decreased from 45.0% in 2010 to 34.6% in 2015/16
- Higher maternal autonomy was associated with lower stunting (aOR = 0.81, p = 0.002)
- The association between maternal autonomy and stunting was likely mediated by maternal education and family wealth
- Child age, maternal education, and family wealth were the most important factors associated with stunting in dominance analysis
Limitations
This is a cross-sectional observational study, so causality cannot be established; the association between maternal autonomy and stunting may be confounded by unmeasured factors. The study cannot determine whether the improvements in stunting between 2010 and 2015/16 were solely due to increased maternal autonomy or other concurrent interventional programs.
Abstract
Child undernutrition is a major health problem in Malawi. We assessed the association between maternal autonomy and child stunting in Malawi. We utilized nationally representative pooled cross-sectional data from the 2010 and 2015/16 Malawi Demographic and Health Surveys (MDHS), which included 7348 mother (28.1 ± 6.8 years, range 15-49 years)-child (27.6 ± 16.7 months, range 0-59 months) pairs. Maternal autonomy composite scores captured decision-making power, tolerance of domestic violence, and financial independence. The nutritional outcome measure was stunting (height-for-age z score < - 2). Logistic regression assessed associations between maternal autonomy and stunting, and dominance analysis evaluated the relative importance of the associated factors. From the two surveys combined, 39.2% were stunted. Stunting decreased from 45.0% in 2010 to 34.6% in 2015/16; concurrently, maternal autonomy improved and was evidently associated with stunting (aOR = 0.81, 95% CI = 0.71, 0.93; p = 0.002). However, this association was probably mediated by other factors associated with improved child nutrition, including maternal education and family wealth, which, along with child age, were associated with stunting in the dominance analysis. Concurrent interventional programs may also have contributed to the decrease in stunting between the surveys, thus moderating the effect of maternal autonomy.

Problem
Child stunting in Malawi
- Intervention
- Increased maternal autonomy (measured as decision-making power, tolerance of domestic violence, and financial independence)
- Population
- 7,348 mother-child pairs from Malawi Demographic and Health Surveys (2010 and 2015/16); mothers aged 15-49 years, children aged 0-59 months
Key finding
Higher maternal autonomy was associated with reduced stunting (aOR = 0.81, 95% CI = 0.71-0.93, p = 0.002)
