Body mass index (BMI) is currently being used by competent authorities as an index of obesity.

Preventive measures to contain the epidemic of obesity have become a major focus of attention.

Studies with high values in most of the variables were assessed to be of high quality and studies with low values were assessed to be of low quality.

Medium quality was assigned to those in the mid-range.

Obesity results from an incorrect energy balance leading to an increased store of energy, mainly as fat.

The major factors that contribute to obesity include over-nutrition, physical inactivity, change of dietary habits, modernization,consumption of high fat, high carbohydrate foods, urbanization and in a minority of patients a physical condition or metabolic disturbance.

Although obesity is a global epidemic that affects every socio-economic class, little is available in the literature on the status of the syndrome in Africa.

This literature review was therefore written in order to highlight the causes, effects and potential mitigation measures of the syndrome with particular interest on the status of the condition in Africa.

Inclusion criteria were used to eliminate non-relevant studies.

The full text of selected articles was then reviewed.
