Within the framework of an international collaborative network, we mea
sured the prevalence of diabetes mellitus in a traditional Yoruba comm
unity in the city of Ibadan, Nigeria, Using a random sampling techniqu
e we enrolled a community sample of 247 men and women, Easting blood g
lucose (FBG) was measured at the community clinic from a fingerstick u
sing the Companion2 Medisense blood glucose meter, The mean FBG was 4.
7mmol/L and 49mmol/L for men and women, respectively. Using the 1985 W
HO criteria, the prevalence of diabetes was 2.8%, There was no signifi
cant rise in FBG with age, Compared to the lowest quartile of the body
mass index (BMI), there was about a 1.5 fold increased risk of develo
ping elevated FBG. The test of trend between FBG and BMI was however n
ot statistically significant, Despite a modest hypertension rate (22.3
%), there was no significant difference in the FBG for hypertensives c
ompared to normotensives. The findings of this study show that the pre
valence of diabetes mellitus in this West African community remains lo
w compared to nations in Western socities, However, in comparison to p
revious estimates from sub-Saharan Africa, the prevalence of adult ons
et diabetes seems to be on the increase.
