Consumption of micronutrient-fortified milk and noodles is associated with lower risk of stunting in preschool-aged children in Indonesia

Abstract

Background: Stunting is highly prevalent in developing countries and is associated with greater morbidity and mortality. Micronutrient deficiencies contribute to stunting, and micronutrient-fortified foods are a potential strategy to reduce child stunting.

Objective: To examine the relationship between the use of fortified powdered milk and noodles and child stunting in a large, population-based sample of Indonesian children.

Methods: Consumption of fortified milk and fortified noodles was assessed in children 6 to 59 months of age from 222,250 families living in rural areas and 79,940 families living in urban slum areas in Indonesia.

Results: The proportions of children who consumed fortified milk and fortified noodles were 34.0% and 22.0%, respectively, in rural families, and 42.4% and 48.5%, respectively, in urban families. The prevalence of stunting among children from rural and urban families was 51.8% and 48.8%, respectively. Children from rural and urban families were less likely to be stunted if they consumed fortified milk (in rural areas, OR = 0.87; 95% CI, 0.85 to 0.90; p < .0001; in urban areas, OR = 0.80; 95% CI, 0.76 to 0.85; p < .0001) or fortified noodles (in rural areas, OR = 0.95; 95% CI, 0.91 to 0.99;p = .02; in urban areas, OR = 0.95; 95% CI, 0.91 to 1.01; p = .08) in multiple logistic regression models adjusted for potential confounders. In both rural and urban families, the odds of stunting were lower when a child who consumed fortified milk also consumed fortified noodles, or when a child who consumed fortified noodles also consumed fortified milk.

Conclusions: The consumption of fortified milk and noodles is associated with decreased odds of stunting among Indonesian children. These findings add to a growing body of evidence regarding the potential benefits of multiple micronutrient fortification on child growth.
