Drivers of Nutritional Change in Pakistan: A Decomposition Analysis

The global reduction in child undernutrition highlights the international and national commitment to prioritizing future generations' health. This study aims to find out the previous trends in nutrition and the key drivers of these changes in different regions of Pakistan. For empirical investigation, we employed a regression-based decomposition model by using two distinct rounds of demographic and health surveys: 2012-13 and 2017-18. Results showed children with stunted growth reduced substantially in Balochistan, while Punjab exhibited the highest progress for underweight children. Regression estimates showed that maternal nutritional status and household wealth were more pronounced in reducing all measures of child malnutrition. Some determinants, including mother age at marriage and prenatal visits to the hospital, are significant only for long-term nutritional status-stunting, while mother education contributed to reducing wasted and underweight children. The rest of the factors, like father education and household environment, appear to play a humble role in explaining nutritional improvements. From disaggregated analysis based on different regions, we found that modeled factors used in this study explained changes disproportionately. Thus, it is recommended to use multidimensional nutrition policies incorporating a broader range of sectors, and region-specific programs should be designed for more effective outcomes.
