1. Overweight and obesity are now the most prominent features of malnutrition in South Africa. Two out of 3 women and almost 2 in 5 men are currently overweight.

2. Up to 5 700 life years could be gained through individual prevention programmes in South Africa every year. When effects on disability are accounted for, interventions can save up to 5 900 years of life in good health (DALYs).

3. How much does prevention cost? How much does it save? Most prevention programmes would cost up to US$ 35 m every year, with individual counselling by family doctors costing up to US$ 58 m. Most prevention programmes will cut health expenditures for chronic diseases, but only by a relatively small margin (up to US$ 7 m per year).

4. Is prevention cost-effective? Prevention can improve health at a lower cost than many treatments offered today by health systems. In South Africa, most of the prevention programmes examined will be cost-effective in the long run (i.e. 100 years) – relative to the standard of US$ 15 000 per year of life gained in good health. Some programmes will take a longer time to produce their health effects and therefore will be less cost-effective in the short run. Fiscal measures will be cost-saving after a few years.

5. Up to 14 700 life years could be gained through a combination of prevention programmes in South Africa every year. Combining several interventions to tackle unhealthy diet and physical inactivity is an efficient way of improving population health. The cost-effectiveness ratio of a prevention strategy including a mass media campaign, food taxes and subsidies, nutritional labelling and marketing restrictions would be US$ 13 500 per life year gained in good health (DALY).

6. The cost of an affordable prevention package in South Africa. A prevention strategy to tackle unhealthy diet and physical inactivity can contribute to a package designed to tackle the main risk factors for chronic diseases, including also tobacco, alcohol, high blood pressure and high cholesterol. In South Africa, such prevention package could be implemented for an annual cost of US$ 3.9 per head. Interventions to tackle unhealthy diets and physical inactivity would cost US$ 0.99 per head
