Nutributter Supplement

This project evaluated the effects of Nutributter, a daily lipid-based nutrient supplement (LNS), on linear growth in Haitian infants.

Location: Cap Haitien, Haiti

Collaborators: Brown School, Washington University in St. Louis, Meds & Food for Kids

Haiti has experienced rapid urbanization that has exacerbated poverty and undernutrition in large slum areas. We aimed to test the efficacy of Nutributter, a daily lipid-based nutrient supplement (LNS) for increased linear growth in young children.

Healthy, singleton infants aged 6-11 mo (n = 589) were recruited from an urban slum of Cap Haitien and randomly assigned to receive: 1) a control; 2) a 3-mo LNS; or 3) a 6-mo LNS. Infants were followed monthly on growth, morbidity, and developmental outcomes over a 6-mo intervention period and at one additional time point 6 mo post intervention to assess sustained effects. 

Key Findings:

  • LNS supplementation for 6 mo significantly increased the length-for-age z score by 0.13 and the weight-for-age z score by 0.12 compared with in the control group after adjustment for child age.
  • The effects were sustained 6 mo post intervention.
  • A low-energy, fortified product improved the linear growth of young children in this urban setting.
