Prevalence of Obesity in Black Subjects with Type 2 Diabetes in Benin
Open Journal of Internal Medicine
Abdominal obesity is often associated with type 2 diabetes, especially in the context of metabolic syndrome. The objective of this study was to determine the prevalence of corpuscular and abdominal obesity in type 2 diabetes in the two major cities in southern Benin. Methods: It was a multicentric, prospective, descriptive and analytical study that had as framework the center for screening and monitoring of diabetes "Banque d'insuline" Ouémé-Plateau in Porto-Novo. The study was a six-month
... d (March-August 2014). Results: We included a total of 400 type 2 diabetics. Women represented 66% of the study population with a sex ratio of 0.52. The mean age of patients was 55.6 ± 10.3 years with extremes of 28 and 87 years. The prevalence of corpuscular obesity (BMI ≥ 30 Kg/m 2 ) was 38.5% in our study population. For the gender, it was 48.5% in women and 19.1% in men with a statistically significant difference (p = 0.0001). The overall prevalence of abdominal obesity in our study population was 87.8%. Almost all of our diabetic women (99.2%) had abdominal obesity versus 65.4% in men (p = 0.0001). All the patients with type 2 diabetes having corpuscular obesity had also abdominal obesity. This abdominal obesity was observed in 80.1% of non-obese diabetic (p = 0.0001). On the contrary, the majority of patients with abdominal obesity (56.12%) had a BMI below 30 kg/m 2 . Conclusion: This study shows a high prevalence of abdominal obesity (87.8%) in our study population compared with the corpuscular obesity (38.5%). Hence, the importance of measuring waist circumference is more than BMI in diabetic patients.
