Effect of choice of guideline on the prevalence of central obesity in Nigerians with type 2 diabetes
International diabetes federation
Background: The presence of central obesity in patients with type 2 diabetes (T2DM) impacts significantly on the management of the disease and its comorbidities. Different cut off points by various research groups has led to confusingly different prevalence data. Aim: To compare the prevalence of central obesity using various criteria in Nigerians with T2DM. Methods: A retrospective study of outpatients of a diabetes clinic in a tertiary health care centre was done. Data obtained from the clinic notes of the patients included the age, gender, DM duration, presence of hypertension, waist (WC) and hip circumferences. The waist-hip ratio (WHR) was appropriately derived. Central obesity was defined according to the following: WHO (WHR > 0.90 in men, >0.85 in women), IDF specific values for Europids (WC > 94 cm in men and > 80 cm in women) and NCEP ATP III (WC > 102 cm in men and > 88cm in women). The results are expressed as mean (SD) and frequencies. Results: There were 568 persons studied, 260 (45.8%) were males and 308(54.2%) were females. The mean ages of the male and female patients were 58.4 (9.9) and 57.3 (9.6) years respectively while the mean duration of diabetes in the male and female patients was 5.8 (6.8) and 6.1 (8.7) years respectively. The frequencies of central obesity using the WHO, IDF (Europids) and NCEP ATP III criteria were 213 (81.9%), 128(49.2%) and 56(21.5%) in males and 263 (85.4%), 283(91.1%) and 227 (73.7%) in females. Conclusion: The WHO criteria gave the highest prevalence rate for central obesity in the entire study population followed by the IDF (Europids specific values) and then the NCEP ATP III. The greatest disparity in the prevalence of central obesity in the males and females was in the IDF (Europids) criteria. Further studies are necessary to determine which criteria are best for defining central obesity in sub-Saharan Africans especially in the female population.
