The investigators have successfully completed a one-year pilot intervention study at two health facilities in Nyanza Region including 140 (n=72 intervention, n=68 control) HIV-infected adults on antiretroviral therapy which evaluated the potential effectiveness of an integrated, multisectoral agricultural and microfinance intervention called "Shamba Maisha" ("Farm Life"), designed to increase household food security and wealth in HIV-affected households. Shamba Maisha includes a) a microfinance loan (~$175) for purchasing agricultural implements and commodities; b) agricultural implements, purchased with the loan, including a human-powered water pump, seeds, fertilizers and pesticides; and c) education in financial management and sustainable farming practices occurring in the setting of patient support groups. The trial demonstrated the feasibility, acceptability, and short-term effectiveness of Shamba Maisha on improving household food security, diet quality and health outcomes of adults living with HIV. The investigators have also successfully completed a one-year companion pediatric study in which they tested preliminary impacts of Shamba Maisha on nutritional outcomes of HIV-affected children under 5 years old who resided in households of participants in the parent study (N=200 children and 126 primary caregivers). At baseline, the investigators observed a significant degree of undernutrition in both groups. They observed statistically significant gains in weight over time for children over six months old in the intervention group (group by time interaction, p=0.01) compared to the control group, but the sample size and follow-up time were insufficient to test effects on height. A larger sample size in a randomized design with longer follow-up period is needed for a definitive test of the effectiveness of this intervention on children's health outcomes.
