Ways to share health messages and reduce the risk of developing non-communicable diseases

The ‘double burden’ of disease

Many low- and middle-income countries are facing a ‘double burden’ of disease. They continue to have the old problems of infectious diseases, but at the same time are experiencing a rapid increase in non-communicable diseases such as diabetes and heart disease. Being overweight is one of the underlying factors.

It is now common to find communities where under-nutrition and overweight exist side by side, particularly in urban areas. Families often change their eating habits when they move to towns and cities. They may save time on cooking by buying ready-to-eat convenience foods, or processed foods. These foods often contain high amounts of fat and/or sugar, which make them tasty but full of hidden calories (energy). Consuming more energy than a person needs leads to them becoming overweight.

Urban diets usually contain more salt and less fibre than traditional diets. Living in cities may also decrease physical activity because people have less physically demanding jobs and can use public transport or cars, rather than walking. Physical inactivity reduces the amount of energy a person needs, making overweight more likely.

What is overweight?

Overweight is when there is too much fat in the body. A quick way to check for overweight is to measure waist circumference. A woman is usually overweight if her waist is 80cm or more. For a man, the figure is 94cm or more. (See below for a diagram illustrating this.)

Attitudes to being overweight 

In South Africa, women’s responses to ‘being large’ included: ‘If you are large, you have a presence and can be easily seen’ … ‘People know you are healthy (i.e. are not HIV positive)’… ‘Husbands prefer fat women’. Attitudes were overwhelmingly positive towards overweight and the risks were not recognised. Yet the con-sequences of being overweight can be life threatening. Being overweight increases the risk of heart disease (including stroke), diabetes, osteoarthritis (a disease of the joints) and some cancers (uterus, breast and co-lon).

Clearly we need to change attitudes about being overweight and increase awareness about these serious risks. However we should be sensitive when communicating with individuals about their weight. 

What is healthy eating?

It is a diet that maintains a healthy weight in adults, enables healthy growth in children, has a variety of foods and provides enough energy and nutrients. 

Tips for healthy eating 

Why eat a variety of foods?

This helps ensure that all essential nutrients will be present. For example, staple cereals like wheat and rice contain no vitamin A, vitamin C or vitamin B12 so these need to be provided from other foods. These vita-mins help to give you good vision, normal growth and development. They are also important in fighting in-fections, healing wounds and making blood cells. 

Why eat wholegrain cereals, legumes and nuts? 

Choose brown bread, brown rice, oatmeal or rolled oats, bulgur wheat or quinoa. 

Why eat plenty of fruits and vegetables?

Aim to have five portions of fruit and vegetables a day. Potatoes, yam, cassava and plantain do not count as a portion.


Why limit fats, oils and fatty foods?


For cooking, choose soya, groundnut, sunflower, olive, rapeseed, safflower, corn, or blended vegetable oils. 

Why limit sugar and sugary foods? 


Why eat less salt? 


Some foods contain hidden salt, including cheese, processed meat, packet and canned soups, stock cubes (for soups etc), processed snacks and ready-to-eat meals. Try not to add salt at the table. However your body does need some salt to work well, particularly in very hot climates where you lose salt through sweating. You may become dizzy or faint if you do not have enough salt in your diet.

Health in pregnancy: avoiding low birth weight 

Low birth weight increases the risk of death during infancy. It also increases the risk of high blood pressure, heart disease and diabetes in adult life. To avoid low birth weight, pregnant women should eat healthily and: 

  • avoid long gaps between meals (snacking is good)
  • not take part in religious fasts 
  • not smoke or chew tobacco
  • avoid alcohol.

Malaria in pregnancy also decreases birth weight. In endemic areas advise pregnant women to sleep under an insecticide-treated net and receive IPT (intermittent preventive treatment) at the antenatal clinic.
