Overview

People living with HIV/AIDS face increased challenges in maintaining proper nutrition. Despite developments in medical treatment, nutrition remains a key component in managing this condition. The challenges that those living with HIV/AIDS face can be the result of the viral infection itself or from the effects of anti-HIV therapy (HAART).

Some of the side effects from HAART that may affect how the body absorbs and utilizes nutrients include fatigue, nausea, and poor appetite. As well, the nutritional needs of people with HIV/AIDS are greater due to their immune system fighting off opportunistic infections that do not normally cause disease in people with healthy immune systems. Medication along with proper nutrition is a major component of maintaining good health and quality of life for people living with HIV/AIDS.

Nutritional need of the HIV/AIDS patient

Energy requirements

For people with HIV/AIDS, energy requirements often increase in order to maintain their regular body weight.. Monitoring caloric intake is important in ensuring that energy needs are met.

Classification

A classification system revised by the Centers for Disease Control and Prevention (CDC), categorizes HIV-infection into 3 clinical stages and addresses the suggested caloric requirements for each stage.

1. Clinical Category A: Asymptomatic HIV

This stage is characterized by Acute HIV. People in this category have estimated needs of 30-35 kcals/kg.

2. Clinical Category B: Symptomatic HIV

This stage is characterized by complications that arise from HIV symptoms. People in this category have estimated needs of 35-40 kcals/kg.

3. Clinical Category C: Presence of AIDS condition

This stage is characterized by having a T-cell count under 200, signaling the presence of an AIDS defining condition and/or an opportunistic infection. People in this category have estimated needs of 40-50 kcals/kg and are at an increased risk of malnourishment.

Multivitamins and supplementation

• There is no consensus regarding the effects of multivitamins and nutrient supplementation on HIV positive individuals. This is partly due to a lack of strong scientific evidence that would support the supplementation of any particular micronutrient.
• Some studies have looked into the use of implementing daily multivitamins into the diet regimens of HIV/AIDS patients.
  • One study done in Tanzania involved a trial group with one thousand HIV positive pregnant women. Findings showed that daily multivitamins benefited both the mothers and their babies. After four years, the multivitamins were found to reduce the women’s risk of AIDS and death by approximately 30%.
  • Another trial in Thailand revealed that the use of multivitamins led to fewer deaths, but only among people in advanced stages of HIV. However, not all studies have provided a positive correlation.
  • A small trial done in Zambia found no benefits from multivitamins after one month of use.
• Regarding individual vitamin and mineral supplement ation, research shows mixed results. Vitamin A supplementation has been shown to reduce mortality and morbidity rates among African children suffering from HIV. The World Health Organization (WHO) recommends vitamin A supplements for all young children 6 to 59 months old that are at high risk of vitamin A deficiency every 4 to 6 months
• In contrast, a trial from Tanzania found that the use of vitamin A supplements increased the risk of mother-to-child transmission by 40%.
• With the inconsistency of these results, scientists have not reached a consensus regarding Vitamin A supplementation and its possible benefits for HIV/AIDS patients.
• Thus, further research is required to determine the relationship between supplements and HIV/AIDS in order to develop effective nutritional interventions.

Global effects of HIV/AIDS on nutrition

Statistics show that HIV/AIDS is most prevalent in the Sub-Saharan African region. And according to the hunger map of 2010, undernourishment is most prevalent in Asia-Pacific and, once again, in Sub-Saharan Africa. Some of the reasons as to why there is a correlation between malnutrition and the presence of HIV/AIDS are listed below.

Food security

Food security is present “when all people at all times have access to sufficient, safe, nutritious food to maintain a healthy and active life”, as defined by the World Food Summit of 1996. It is set on the basis of food availability, food access, and proper food use. The difficulty for some people suffering from HIV and AIDS involves how they must obtain food security because the virus increases fatigue, compromising their ability to work in order to provide food and food preparation. This impact is even greater on those living in poverty in rural areas, where providing food is largely based on farming and other household chores.
