Impact of an integrated health, nutrition and early child stimulation intervention package delivered to preterm and small for gestational babies during infancy, on body composition

Preterm and small for gestational age (SGA) infants represent a significant public health concern, particularly in South Asia, where they account for nearly 41% of live births. These infants face dual risks of excess fat gain and poor skeletal development, increasing their susceptibility to adult non-communicable diseases (NCDs) through metabolic programming. Current evidence suggests these risks stem from suboptimal growth trajectories and early-life nutritional deficiencies. While interventions targeting body composition have shown some promise, evidence on comprehensive approaches is sparse, particularly in low- and middle-income settings.

This study, embedded in an ongoing RCT (pubmed.ncbi.nlm.nih.gov/38331842/), seeks to assess the impact of integrated health, nutrition, and early child stimulation interventions on body composition at 12 months of age. Interventions include breastfeeding support, growth monitoring, nutritional supplementation with a milk cereal mix, and early child stimulation activities. Using a fan-beam Dual-energy X-ray Absorptiometry (DXA) with infant-adapted Lunar software, it will measure lean mass, fat mass, and bone mineral density (BMD). The findings aim to optimize growth interventions for preterm and SGA infants, informing policies to mitigate the dual burden of malnutrition and NCD risk in vulnerable populations.
