Objective: Fat percentage and its distribution exert a strong influence on the development of glucose intolerance and type 2 diabetes. The aim of this study was to evaluate the impact of body adiposity on the presence of prediabetes and type 2 diabetes in a sample of Egyptian adults.
Methods: This is a cross-sectional study on 866 Egyptian adults aged between 20 and 75 years. The study evaluated the presence of prediabetes or type 2 diabetes and compared BMI, percentage of body fat (BF%), visceral fat, waist circumference, and the waist-to-hip ratio between normoglycemic patients and individuals with prediabetes or type 2 diabetes.
Results: BF% was significantly higher in prediabetic and diabetic individuals than in normoglycemic individuals. Both prediabetic and diabetic lean and obese men showed higher visceral fat levels than their corresponding normoglycemic counterparts.
However, among women, a significant increase was observed only in prediabetic obese individuals. There is coexistence of diabetes and hypertension in obese and old patients.
Conclusion: Type 2 diabetes is more frequent in older obese Egyptians and is associated with elevated systolic and diastolic blood pressure. Although total BF% is an important risk factor for type 2 diabetes, visceral fat is considered the most strongly related factor to the disease especially in men.
