Abstract
AIM

To estimate the prevalence of diabetes in the rural population of Tessekere (Senegal) and investigate associated risk factors.

METHODS

Data from a 2015 survey of 500 individuals age 20 and over representative of the population of the municipality of Tessekere were used. Sociodemographic characteristics, health related variables, capillary whole blood glucose, and weight and height measurements of individuals were collected during face-to-face interviews. Statistical analyses used were bivariate tests and binary logistic regressions.

RESULTS

The percentage of individuals having impaired fasting glucose (IFG) is 6.6%. Those with fasting blood glucose (FBG) levels ≥ 126 mg/dL and/or currently being treated for diabetes is 4.2%. Only mean body mass index (BMI) is significantly higher among diabetic individuals and among those having FBG levels ≥ 110 mg/dL. After adjustment for sex, age, educational level, BMI and hypertension, only BMI is associated with diabetes.

CONCLUSION

Prevalence of diabetes and IFG in our study correspond to the high range of rural sub-Saharan Africa prevalence. Diabetes is thus becoming a pressing public health concern, even in rural areas. But the risk factors identified in Tessekere suggest that the diabetes epidemic is still in the early stages, such that concerted action would make it possible to contain the devastating impact of this chronic condition.

Keywords: Anthropology, Epidemiology, Sub-Saharan Africa, Diabetes

Core tip: Our study is one of the first, to our knowledge, to estimate the prevalence of diabetes in a rural Senegalese area. In the Tessekere municipality, diabetes prevalence is 4.2%, and that of impaired fasting glucose is 6.6%, corresponding to the high range of prevalence observed in rural sub-Saharan Africa. In our population study, emerging risk factors such as depression and material well-being (identified mainly in developed countries) are not associated with diabetes, indicating that this epidemic is in the early stages in this region.
