•
Malnutrition is a common
complication of HIV infection
•
Malnutrition further exacerbates
the immune-suppression caused
by HIV
•
Malnutrition is therefore part of a
cycle whereby it both contributes
to HIV disease progression and
is caused by HIV as indicated in
the illustration to the right
•
People are malnourished if:
•
their diet does not provide
adequate nutrients for growth
and maintenance or
•
they are unable to fully utilize
food due to illness
(undernutrition) or
•
they consume too many calories
(over-nutrition)

Good nutrition can help:
•
people feel strong physically and mentally
•
strengthen the immune system to fight infection
•
people stay productive and physically able
•
prevent undernutrition
•
improve drug adherence and effectiveness
•
manage common symptoms of illness and drug
side effects

Poor nutrition can:
•
Weaken the immune system
•
Increase vulnerability to
infections
•
Reduce the body’s ability to
recover from infections
•
Increase the risk of developing
non-communicable diseases

•
Identifies people at risk of malnutrition for early
intervention or referral
•
Detects eating habits that increase disease risk
•
Identifies needs for nutrition education and
counselling
•
Identifies local food resources
•
Tracks growth and weight trends
•
Establishes a framework for a Nutrition Care Plan
•
Patients that are losing weight should be actively investigated and
monitored until the cause is found or the weight loss resolves.
•
As a minimum, TB screening and a random blood glucose level should be
performed.
•
Further investigations should be done as indicated by history and
examination.
•
Refer any patients with documented ongoing weight loss without an
obvious cause. Extrapulmonary TB or malignancies may need to be
excluded
•
Weight Gain
•
Weight gain at an acceptable rate in a patient who has recently started
ART is reassuring and usually indicates immune system recovery
•
However, PLHIV on ART for many years can have a higher risk for
hypertension, diabetes and cardiovascular disease. Excessive weight
gain should therefore be avoided.

In the presence of WHO stage 2 conditions or higher,
PLHIV should increase their energy intake by 20-30% over
the recommended energy intake levels of healthy, non-HIV-
infected individuals of the same age, sex, and physical
activity levels.
•
Good nutrition is best achieved by consuming a varied diet
rich in micronutrients, especially vitamins A, B6, B12,
selenium, iron, and zinc.
•
However, a daily multivitamin may
p
rovide nutrients in
patients who are not able to get a complete or balanced
diet, or those who have poor appetite, financial restraints,
or other factors that may contribute to malnutrition

Thank you!
Malnutrition is common in people living with HIV and TB, exacerbating immune suppression and disease progression. Good nutrition can strengthen the immune system, improve drug adherence, and manage symptoms, while poor nutrition weakens immunity and increases vulnerability to infections. Consequences of malnutrition include reduced survival, increased morbidity, and socio-economic issues. Understanding the link between HIV, TB, and nutrition is vital in improving health outcomes for affected individuals.

Learning Objectives By the end of this session participants should be able to: Provide the basic concepts of the relationship between food, nutrition and HIV/AIDS Discuss the general dietary needs and practices to reduce morbidity, mortality and progression of HIV to AIDS
The Link between HIV and Nutrition (1) Malnutrition is a common complication of HIV infection Malnutrition further exacerbates the immune-suppression caused by HIV Malnutrition is therefore part of a cycle whereby it both contributes to HIV disease progression and is caused by HIV as indicated in the illustration to the right People are malnourished if: their diet does not provide adequate nutrients for growth and maintenance or they are unable to fully utilize food due to illness (undernutrition) or they consume too many calories (over-nutrition)
Importance of Nutrition Good nutrition can help: people feel strong physically and mentally strengthen the immune system to fight infection people stay productive and physically able prevent undernutrition improve drug adherence and effectiveness manage common symptoms of illness and drug side effects This Photo by Unknown Author is licensed under CC BY-SA
Poor Nutrition Poor nutrition can: Weaken the immune system Increase vulnerability to infections Reduce the body s ability to recover from infections Increase the risk of developing non-communicable diseases This Photo by Unknown Author is licensed under CC BY- NC-ND
What are Some Consequences of Malnutrition in PLHIV and TB Clients? Poor food absorption Poor growth Increased morbidity Metabolic complications Increased risk of OIs Reduced survival Increased cost of treating malnutrition- related illness Increased risk of MTCT of HIV Socioeconomic problems, e.g.: food insecurity poverty
The Vicious Cycle between Undernutrition and HIV and/or TB
Nutrition Assessment and Intervention
Importance of Nutrition Assessment Identifies people at risk of malnutrition for early intervention or referral Detects eating habits that increase disease risk Identifies needs for nutrition education and counselling Identifies local food resources Tracks growth and weight trends Establishes a framework for a Nutrition Care Plan
Nutritional Assessment Patients that are losing weight should be actively investigated and monitored until the cause is found or the weight loss resolves. As a minimum, TB screening and a random blood glucose level should be performed. Further investigations should be done as indicated by history and examination. Refer any patients with documented ongoing weight loss without an obvious cause. Extrapulmonary TB or malignancies may need to be excluded Weight Gain Weight gain at an acceptable rate in a patient who has recently started ART is reassuring and usually indicates immune system recovery However, PLHIV on ART for many years can have a higher risk for hypertension, diabetes and cardiovascular disease. Excessive weight gain should therefore be avoided.
General Guidelines for People Living with HIV and AIDS (1) Get individualised nutrition therapy, see dietitian for further assessment, counselling & nutrition support Get screened for communicable and non- communicable diseases Get weighed regularly and have weight recorded Advise weight loss for overweight and obese patients Regular balanced meals, with good portion control Increased intake of high fibre foods
General Guidelines for People Living with HIV and AIDS (2) Reduce amounts of unhealthy fats, salt, sweets, sugary foods and sugar containing beverages Consider cultural, social and economic issues Include physical activity as part of healthy lifestyle Discourage smoking, alcohol consumption Maintain good hygiene and sanitation Prevent and seek early treatment for infections Seek dietary advice on managing symptoms. Take medicines and food as advised by provider
South African Food Based Dietary Guidelines to Promote a Healthy Lifestyle Refer to pages 183 184 of your participant manual to see a chart with these guidelines
Increased nutritional requirements in PLHIV In the presence of WHO stage 2 conditions or higher, PLHIV should increase their energy intake by 20-30% over the recommended energy intake levels of healthy, non-HIV- infected individuals of the same age, sex, and physical activity levels. Good nutrition is best achieved by consuming a varied diet rich in micronutrients, especially vitamins A, B6, B12, selenium, iron, and zinc. However, a daily multivitamin may provide nutrients in patients who are not able to get a complete or balanced diet, or those who have poor appetite, financial restraints, or other factors that may contribute to malnutrition
Portion Control Tips (1) A meal should consist of: one meat dish option an option of vegetarian for those who are vegetarian one starch option two vegetable options one fruit option and water
Portion Control Tips (2) Size Estimate portion size for. . . starchy foods e.g. rice, samp, cooked pap, pasta whole fruit meat, fish or chicken vegetables cooked beans split peas lentils or nuts all oils, margarines or mayonnaise for peanut butter or hard cheese Fistful = 1 cup Palm of hand 2 open handfuls 1 open handful Tip of thumb = 1 teaspoon
NOTE: Nutrition intervention is usually individualised based on patient requirements, medication, other complications etc. Thus, it is still critical that HIV and T.B clients are referred to a registered dietitian for individualised nutrition assessment and intervention.
Key Learning Points HIV, nutritional status and immune function are linked It is important to identify adults and children that are malnourished and refer them to dieticians for nutritional support People that are infected with HIV have increased nutritional requirements Nutritional advice can be given to people that experience symptoms of HIV or side effects from its treatment
Any Questions? Thank you!
