OBJECTIVE - To perform an epidemiological study of the prevalence of d
iabetes in Mauritania, West Africa, with little data available on diab
etes in West Africa. RESEARCH DESIGN AND METHODS - The study was perfo
rmed with a representative sample of the Mauritanian population. A ran
dom selection of the study population (n = 744) was drawn by a cluster
sampling method. Screening for diabetes was made by capillary blood g
lucose (CBG) measurement, using strips analyzed by reflectance meter.
Criteria for the diagnosis of diabetes were those of the World Health
Organization (WHO). RESULTS - The survey performed a screening of 744
subjects whose sex distribution was 307 men and 437 women. Their mean
age was 34.6 +/- 15.2 years, and their mean BMI was 22.7 +/- 5.1 kg/m(
2), with a significant difference for BMI between men (20.0 +/- 2.9 kg
/m(2)) and women (24.3 +/- 5.5 kg/m(2)). According to the study criter
ia, we found 14 diabetic patients (4 men, 10 women). The crude prevale
nce of diabetes was 1.88% (95% CI 0.90-2.86). The difference in preval
ence by sex was 1.30% (95% CI 0.00-2.60) for men and 2.29% (95% CI 0.8
9-3.43) for women. For the truncated 30- to 64-year-old age-group, the
crude prevalence was 2.84%; the age-adjusted prevalence for the same
30- to 64-year-old age-group, using the standardized age distribution
of Segi (10), was 2.61%. CONCLUSIONS - With a crude prevalence of diab
etes of 1.88% and an age-adjusted prevalence of 2.61%, Mauritania may
be classified among the countries with a low prevalence of diabetes, a
finding which is not surprising, considering the low level of develop
ment of this region of Africa.
