How nutrition education can make a difference to people with HIV in Nigeria
HIV and AIDS are still global health problems and sub-Saharan Africa remains the most affected region. Globally, around 770,000 people died from AIDS-related conditions in 2018, 160,000 of them in West and Central Africa.
The standard treatment for HIV consists of a combination of at least three antiretroviral drugs. But providing antiretroviral therapy without proper, nutritious diets may compromise the effectiveness of the treatment.
People with HIV have higher energy needs than those of people without HIV. And the World Health Organisation recommends that antiretroviral medications be taken with food to avoid possible side effects such as headaches and stomach problems, which can lead to weakness and weight loss.
Because of the importance of good nutrition in the management of HIV, we aimed to develop and test a nutrition education program for adults living with HIV in the Nigerian context. We wanted to evaluate their knowledge of nutrition, their actual diets and the effect on their bodies—in short, the program's impact on their health and quality of life.
We found that the education program helped people to choose healthy foods and this improved their physical well-being. This experience could contribute to other education programs aimed at supporting people with HIV to have a better quality of life.
We started by studying the existing Nigerian nutrition guidelines for adults living with HIV. The nutrition information and recommendations were the same for all adults, whether they had HIV or not. The general premise of the Nigerian national dietary guidelines is to promote good dietary practices and to avoid alcohol consumption and smoking.
There are no details on key issues relating to HIV and nutrition such as how individuals can improve the variety of foods they eat, how they can get important vitamins and minerals, and how they can access clean drinking water despite limited resources.
In addition, there isn't much appropriate nutrition information available to public health care staff and patients.
We wanted to design a program that would plug this gap by teaching adults with HIV how to eat healthy foods with limited resources.
Our research, in the form of a nutrition education intervention, focused on outpatients receiving HIV treatment at two selected hospitals in Abeokuta, southwestern Nigeria.
First we conducted a needs assessment in a similar group, which revealed poor quality of life, high consumption of unvaried meals, poor nutrition knowledge and unhealthy eating behavior. We used this information to develop contextualized nutrition education materials. Health care workers could use these materials to provide nutrition education specifically for patients with HIV, such as planning varied meals, the relationship between diet and medication, and dealing with barriers to healthy eating.
The content of the program also covered the importance of hygiene and exercise, how to deal with problems like diarrhea and anemia, and how to shop for healthy food within a limited budget.
We developed a trainer's manual, brochures, participant's workbook and flipcharts. We also evaluated the impact of the education materials on the participants before and after the intervention. And we followed up with them for 12 weeks after the intervention.
Better nutrition choices
We found that using the communication materials we developed could influence the participants' decisions about healthy food choices and access. The nutrition education program led to some significant improvements.
Participants were able to function better physically and their activities weren't as limited by pain or weakness compared with the control group who didn't receive nutrition education. Participants who received our nutrition education intervention had better nutrition knowledge, quality of life and dietary diversity scores compared to the control groups.
The intervention we designed showed that people don't need to have more money to make better nutrition choices. They can and do improve their well-being when they have more knowledge. And our program was effective in imparting this knowledge. We believe that our findings could be useful to improve programs that help poor people living with HIV to access healthy food.
