The study was descriptive and cross-sectional in design with a sample size of 169 HIV/AIDS adult patients attending The Mildmay Centre that were selected consecutively on a walk in basis between October and December 2007. The data were collected using an interviewer-administered questionnaire including questions about their socio-demographic, economic, health status, 24 hour dietary recall and an individual dietary diversity score tool (FAO/Nutrition and Consumer Protection Division, version of May 2007) and focus group discussions. Descriptive statistics and multiple logistic regression were used to determine dietary diversity and its associated factors.
