Introduction: The government of Indonesia runs a food supplementation programme in the form of biscuits for undernourished pregnant mothers. However, a home-delivered cooked foods programme using catering services has not been explored in Indonesia. This study aimed to determine the effect of home-delivered cooked foods and nutrition education on pregnant women’s gestational weight gain. Methods: This study employed a non-randomised controlled, open-label, parallel design. It enrolled 66 women consecutively assigned to intervention and control groups. The intervention group received home-delivered cooked foods and nutrition education, while control group received usual care at Public Health Centres (PHCs). Results: After two months of intervention, the average increase in body weight of women in intervention group was 4.7±3.0 kg, which was significantly higher than that observed in control group (3.3±1.8 kg). After adjusting for maternal nutritional status, weight before pregnancy, height, gestational age, and age, mothers who received home-delivered cooked foods and nutrition education gained 1.50 kg (95% CI 0.31, 2.70, p=0.015) more weight than those who did not. Conclusion: Home-delivered cooked foods combined with nutrition education improved body weight of pregnant women at nutritional risk. Further studies are recommended to determine impact of home-delivered cooked foods on pregnancy outcomes. These study findings advocate and support Indonesian and local governments in potentially implementing a programme that offers home-delivered cooked foods through cateringservices to pregnant women at nutritional risk.
