The nutritional situation in Tanzania (TZ) is already facing these three forms of malnutrition. Overweight and obesity occur due to a positive balance of energy intake, which is – despite the dietary intake – also linked to an inadequate level of physical activity. Data on physical activity levels of the Tanzania population are limited. The increased prevalence of overweight and obesity can be partly attributed to the urbanized lifestyle leading to unhealthy dietary practices and increasing levels of physical inactivity/sedentary behaviour, fuelling a rise in diet-related non-communicable diseases (NCDs), such as type 2 diabetes, cardiovascular disease and certain forms of cancer. All these risk factors are lifestyle related and it is important to address changes in dietary patterns simultaneously with the levels of physical activity that a country such as Tanzania is transiting into to combat the triple burden of malnutrition.
