Prevalence of obesity in nigerians with type 2 diabetes mellitus seen in a secondary medical center
AbstractBackground: Obesity increases the cardiovascular disease burden in type 2 diabetes mellitus (DM). There are few reports on obesity in type 2 DM patients in Edo State, Midwestern Nigeria.
Objective: To determine the prevalence of obesity in Nigerians with type 2 DM seen in a secondary medical center.
Methods: This was a cross-sectional study of Nigerians with type 2 DM attending Faith Medical Center, Benin City. Data documented included the patient’s age, sex, and duration of DM, body mass index (BMI), waist circumference (WC), hip circumference, waist- hip ratio (WHR) and systolic and diastolic blood pressure.
Results: The study group consisted of 370 (135 males, 235 females) Nigerians with type 2 DM. The mean age of all subjects was 57.57+ 11.06 years with a range of 34-90. One hundred and twenty nine (35%) of them were hypertensive. Their mean BMI was 28.15 ± 4.98 kg/m-2 (females 29.2 ± 5.28 kg/m-2, males 26.7 ± 4.05 kg/m-2, P = 0.001), mean waist circumference was 92.42 ± 11.71cm (females 96.93 ± 12.11cm, males 92.77 ± 10.52cm, P = 0.001).Generalized obesity (BMI >30kg/m-2) was present in 32.9% (males 21.1%, females 39.7%, P < 0.05), abdominal obesity in 76.2% of the females and 19.5% of the males. BMI correlated positively with WC, r = 0.82, P < 0.001; and with WHR, r = 0.41, P = 0.001. WC vs. WHR, r = 0.35, P = 0.001.
Conclusion: The prevalence of obesity in Nigerians with type 2 DM seen in this hospital Diabetes Clinic is 32.9%.
