Malnutrition in Older Adults in Sub-Saharan Africa

Introduction

 What is Malnutrition?

Malnutrition means not getting enough of the right nutrients; whether from too little food, poor-quality food, or the body not absorbing nutrients well. In older adults, malnutrition is a serious health problem that can lead to weakness, illness, and poor quality of life.

Discussion
 Why It Matters in Sub-Saharan Africa

In Sub-Saharan Africa, many older people live in poverty, rural areas, or extended families where resources are stretched. They may be overlooked during food distributions or depend on others for meals. In African culture, older adults often prioritize the nourishment of their children and grandchildren above their own.

Signs of Malnutrition in the Elderly

Look out for:

  • Noticeable unintended weight loss
  • Weaknesses or feeling tired all the time
  • Poor wound healing
  • Loss of appetite
  • Loose or missing teeth, making chewing difficult
  • Swelling in the legs (can be from protein deficiency)
  • Confusion or frequent illness
  • Dry, thin and weak hair and skin
Common Causes
  • Low income or food insecurity
  • Dental problems (missing teeth, gum pain)
  • Chronic diseases like diabetes, TB, or HIV
  • Swallowing problems
  • Loneliness or depression
  • Limited access to diverse, nutritious foods
  • Traditional beliefs that discourage older adults from eating certain foods
Nutritional Needs of Older Adults

Elderly people need:

  • High-quality protein (beans, eggs, meat, fish, groundnuts)
  • Vitamins and minerals (from fruits and vegetables)
  • Plenty of fluids (especially clean drinking water)
  • Energy foods (like maize, cassava, yams, or rice)

Even small, frequent meals are better than none.

 What Can Be Done?

At Home:

  • Encourage eating small meals often
  • Use local, affordable ingredients (e.g. moringa, groundnuts, locust beans, beans, soya beans, meat, fish, sweet potatoes)
  • Offer soft or mashed foods if chewing is difficult
  • Help them eat if they have weaknesses or tremors
  • Make meal -times social and relaxed.

At Clinics or Hospitals:

  • Screen regularly for signs of undernutrition
  • Check weight, appetite, and strength
  • Provide nutrition counselling
  • Refer to dietitians or nutritionists if available
  • Treat any underlying conditions (like infections or mouth pain or problems)
Support from the Family and Community
  • Don’t assume elders eat last or less—include them in meal planning
  • Watch for signs of food neglect or isolation
  • Share knowledge about affordable nutritious options
  • Encourage intergenerational support (grandchildren helping grandparents)

🗣️ Older adults need good nutrition to stay strong, prevent disease, and live with dignity. With small actions and family care, malnutrition can be prevented and treated.
