Nutritional status of under-five children in HIV-affected households in western Kenya

Abstract

Background: Households affected by HIV/AIDS are at an increased risk for food insecurity and malnutrition. Poor nutrition contributes to more than a third of all deaths associated with infectious diseases among children under 5 years of age in developing countries. With increased household food insecurity, and a greater disease burden associated with HIV/AIDS, the growth of children under five could be impacted, resulting in increased malnutrition for this vulnerable group. Objective: To determine whether there is an association between the type of household (HIV-affected compared with HIV-unaffected) and the nutritional status of children under 5 years of age residing in these households. Methods: The study was set in a Millennium Village Project site in western Kenya and used a cross-sectional design to compare the stunting, wasting, and underweight status among 102 and 99 under-five children living in HIV-affected and -unaffected households, respectively. Height-for-age, weight-for-age, and weightfor- age z-scores were calculated based on the World Health Organization growth standards and compared. Proportions, means, and standard deviations were used to describe the data. The data were analyzed with the use of the chi-square test for comparison of proportions and the independent t-test for comparison of means. Results: Children in HIV-affected households had a significantly higher degree of stunting (height-for-age lt; SD) than children in unaffected households (25.5% vs. 9.1%, p = .002). The degree of wasting and underweight did not differ significantly between HIV-affected and -unaffected households. Conclusions: Residing in HIV-affected households is associated with stunting in children under 5 years of age. © 2011, The United Nations University.
