Malnutrition in children is a challenge in South Asian countries, and understanding its relation with variety of social and economic conditions is imperative. The present systematic review examined the association between maternal employment and the nutritional status of children up to twelve years old from South Asia. An electronic search for research articles published in the English language between January 2011 and December 2024 was conducted in PubMed, Science Direct, and Web of Science databases. A total of 10,247 articles from five South Asian countries were screened, resulting in the inclusion of 19 studies in the review based on well-defined inclusion and exclusion criteria. The findings showed that the association between maternal employment and children's nutritional status was context-dependent, with adverse effects in children (stunting, wasting, and growth failure) when mothers worked in unskilled sectors-in low-paying jobs. Children of urban mothers had poor nutritional status, often exacerbated by the lack of or limited childcare support and financial assistance during their work absences. Additionally, many South Asian countries implemented maternal and paternal leave policies and benefits; however, the implementation challenges reduced maternal access to these benefits and predominantly favored mothers working in formal sectors. This systematic review underscores the necessity to strengthen the employment benefit programs for working women in South Asian countries, especially for mothers working in informal sectors. The provision of childcare assistance and supplementary financial benefits to women employed in informal sectors is essential to improve the child nutritional outcomes.
