Challenges and limitations

A key factor in the effectiveness of nutrition interventions on body weight in PLWHAs is the stage of disease progression. However, the lack of widespread voluntary counselling and testing, particularly in many African countries, means that individuals may not know their status. This is compounded by fear of stigma and discrimination, which prevents people from testing for HIV. As a result, individuals are accessing services at later stages of the disease’s progression, which reduces the effectiveness of interventions.

PLWHAs require a continuum of care that integrates relief, rehabilitation and development interventions, and which is responsive to the changing nutritional requirements of individuals at different stages of disease progression. In the absence of such an integrated approach, the positive impact of individual interventions, such as therapeutic feeding to reverse severe malnutrition, may be lost. Currently, the breadth of nutrition interventions is too often limited by lack of capacity. Most interventions aimed at providing food assistance to vulnerable groups are taking place without trained staff or without additional nutritional advice/education, and very few implementers have full time nutritionists working on the projects. In addition, while food rations are seen as supplementary, they are often the only form of nutrition. The current composition of food baskets does not fulfil all the nutritional requirements of individuals.

A further limitation of many nutritional interventions for HIV and AIDS is that they concentrate on medical treatment and do not tend to address other important needs such as safe water, sanitation and food security. Unless nutrition interventions are integrated into other sectors, their impact will not be sustainable or cost-effective. A focus on high cost food supplementation may also result in decreased resources for longer term, more sustainable interventions.

A number of equity issues need to be taken into consideration when developing policy and programmes. The targeting of interventions, while a cost-effective means of ensuring that the most vulnerable access services, could lead to social disharmony if selection is based purely on households affected by HIV and AIDS. This approach could also lead to an increase in stigma and discrimination. Targeting for agricultural and rural development interventions is complicated by the fact that the most vulnerable households are often the ones least able to participate. As a result, there is a need to shift the focus from vulnerability to improving household and community resilience, and the subsequent mitigation of the impact of HIV and AIDS.
