Sri Lanka has achieved significant progress in maternal and child health indicators over the years. However, nutritional indicators have remained stagnant due to various reasons, contributing to both under and over-nutrition and impacting the country's economic and social landscape. Mothers' Support Groups (MSGs) have emerged as a powerful community initiative to address health and nutritional challenges. These groups, established in 2002, aim to promote good health practices through community mobilization and empowerment. Despite their proven effectiveness, the COVID-19 pandemic and economic crises have impacted MSG activities. This case study examines the establishment, development, and challenges of MSGs in the Colombo district, offering recommendations for improvement.
