HIV and Nutrition among Women in SubSaharan Africa

Overview

SubSaharan Africa bears a disproportionate share of the global HIV burden, with women accounting for more than half of all new infections in the region. Nutrition plays a central role in the health of women living with HIV (WLHIV) because it influences immune function, disease progression, and the effectiveness of antiretroviral therapy (ART). At the same time, many women in the region face chronic food insecurity, micronutrient deficiencies, and socioeconomic barriers that compound the impact of HIV.

This page summarizes the key nutritional issues confronting WLHIV in SubSaharan Africa, examines how HIV infection alters nutritional needs, and highlights evidencebased strategies to improve outcomes.

Nutrition Challenges in the Region

Food Insecurity

More than 30% of households in SubSaharan Africa experience moderate or severe food insecurity. Seasonal hunger, reliance on rainfed agriculture and limited market access contribute to insufficient caloric intake, especially for women who are often the primary caregivers.

Micronutrient Deficiencies

Common deficiencies include iron, vitamin A, zinc, and folate. These nutrients are essential for maintaining a robust immune response and preventing anemia, which is already prevalent among pregnant women.

Undernutrition and Overnutrition

While undernutrition remains a major concern, urbanisation has led to a rising prevalence of overweight and obesity. Dualburden households may have a child who is stunted while an adult mother is overweight, creating complex health risks.

GenderSpecific Barriers

• Limited decisionmaking power over household food purchases.
• Cultural practices that prioritise mens nutritional needs.
• Stigma that can restrict WLHIV from accessing community nutrition programs.

How HIV Affects Nutritional Status

HIV infection accelerates metabolic demands and disrupts nutrient absorption:

• Increased Energy Expenditure: Up to 10% higher basal metabolic rate in untreated infection.
• Malabsorption: Damage to gut mucosa reduces uptake of fats, vitamins and minerals.
• Altered Body Composition: Loss of lean muscle mass (cachexia) and lipodystrophy are common.
• DrugNutrient Interactions: Some ART regimens can cause nausea, diarrhoea, or interfere with folate metabolism.

Effective Nutrition Interventions

1. Integrated Food and Nutrition Programs

Combining ART delivery with food assistance (e.g., fortified blended foods, cash transfers) improves adherence and viral suppression rates. Randomised trials in Kenya and Malawi showed a 1215% increase in ART adherence when participants received monthly food rations.

2. Micronutrient Supplementation

Evidence supports supplementation with:

• Iron (when anemia is confirmed) reduces fatigue and improves quality of life.
• VitaminA lowers the risk of opportunistic infections in pregnant WLHIV.
• Multivitaminmineral (MVM) complexes associated with modest increases in CD4 count.

3. Nutrition Counselling

Tailored counselling that addresses local diets, cooking methods and budgeting can empower women to make healthier choices even in resourcelimited settings. Group sessions have the added benefit of reducing stigma.

4. Targeted Support for Pregnancy & Lactation

Supplementary feeding programmes for pregnant WLHIV (e.g., readytouse therapeutic foods) reduce mothertochild transmission and improve birth outcomes.

5. CommunityBased Agritech Initiatives

Home gardens, smallscale livestock and biofortified crops increase household dietary diversity and provide a sustainable source of protein and micronutrients.

Policy Recommendations

1. Integrate Nutrition into HIV Care Guidelines. National HIV programmes should mandate routine nutritional screening, micronutrient supplementation and referral to dietetics services.
2. Scale Up Conditional Cash Transfer Schemes. Linking food assistance to ART pickup improves retention and reduces foodrelated nonadherence.
3. Strengthen Supply Chains for Therapeutic Foods. Ensure that fortified blends and readytouse supplements are locally produced to lower costs.
4. Promote GenderResponsive Agriculture. Support women farmers with training, inputs and market access so they can produce nutrientrich foods for their families.
5. Invest in Research and Monitoring. Collect disaggregated data on nutrition outcomes among WLHIV to inform adaptive programming.

By addressing the intertwined challenges of HIV and nutrition, stakeholders can improve the health of women, reduce transmission rates and advance progress toward the Sustainable Development Goals.
