Aim: The Ministry of Health in Malawi has scaled-up antiretroviral therapy (ART) for HIV infection. However, the majority of Malawians heavily depend on maize-based stiff porridge (nsima), a protein-deficient staple, a practice that exacerbates wasting and ultimately compromises the success of ART programming. This pilot study was conducted to evaluate the efficacy of utilising soybean-enriched nsima as a strategy for managing HIV-related wasting among resource-poor people.
Methods: A before and after designed study involving 25 wasted (<18.5 BMI (body mass index)) to normal (18.5-24.9 BMI) HIV-positive rural women (21-40 years) taking ART and provided with soybean-maize flour (20 kg/month for 3 months) prepared from hydrothermally treated soybeans and maize in the ratio of 1:4 (wt/wt). Anthropometry was performed at baseline and every month for the 3-month study period. Paired sample t-tests were used to test for changes in body mass and BMI between baseline and the subsequent months.
Results: Statistically significant (P < 0.001) cumulative mean weight gain for the first, second and third month of the study were 1.6, 2.1 and 2.9 kg, respectively. The number of participants with low BMI reduced from 6/25 at baseline to 2/25 after 3 months, and the mean BMI improved from 19.3 to 21.1 kg/m2 .
Conclusions: Nsima prepared from a blend of maize and hydrothermally treated soybeans could feasibly be used to prevent and manage wasting among resource-poor people living with HIV/AIDS in sub-Saharan Africa who rely on maize as a major staple.
