Gender-specific associations of body mass index and waist circumference with type 2 diabetes mellitus in Chinese rural adults: The Henan Rural Cohort Study

INTRODUCTION: Many studies have shown the association of waist circumference, waist hip ratio and body mass index with type 2 diabetes mellitus. Waist circumference and waist hip ratio have been used as measures of central obesity and body mass index has been used as a measure of general obesity. Objective of this study is to find out which type of obesity is better for prediction of risk of type 2 diabetes mellitus. MATERIAL AND METHODS:Total 100 participants with confirmed diagnosis of type 2 DM with age group 35-80 years were selected for the study. Anthropometric measurements like height, weight, waist circumference (WC) and hip circumference were measured and body mass index (BMI) and waist hip ratio (WHR) were calculated. Area under receiver operating characteristic (ROC) curve was used for correlating the parameters with type 2 diabetes mellitus in both male and female patients. RESULTS: Area under ROC curve, a measure of performance of the indices in predicting diabetes in total subjects, was found to be highest for waist hip ratio (0.840) followed by waist circumference (0.688) and BMI (0.608). Similarly, area under ROC curve was found maximum for waist hip ratio followed by waist circumference and body mass index in case of male and female patients. CONCLUSION: The present study concludes that anthropometric indicators of central obesity (WHR and WC) are more predictive for type 2 DM than anthropometric indicator of general obesity (BMI).

Background: Excess weight contributes to the development and progression of Type 2 diabetes mellitus (T2DM). Distorted body image amongst urban Black women and the perception that thinness is linked with HIV, may however be compounding the problem, particularly in areas with a high HIV burden.Objectives: This study aimed to compare the perception of body image in urban Black women with and without T2DM.Methods: A cross-sectional comparative study was conducted on 328 Black women systematically sampled into two groups (with and without T2DM). Body mass index (BMI) (weight [kg]/height[m2]) was determined and the adapted Stunkard Body Image Silhouettes for Black women was used to determine perceived body image (PBI).Results: Seventy-two per cent had T2DM and in this group 89% were obese, with a mean BMI of 39.5 kg/m2 (s.d. ± 8.5). In the non-diabetes group (NDG) 44% were obese, with a mean BMIof 31.3 kg/m2 (s.d. ± 9.0) Black women underestimated their body image across all weight categories (p < 0.05). Both groups (99% of the study group) also perceived thinness as being associated with HIV.Conclusions: This study identified an incongruence between PBI and actual BMI amongst urban Black women. This, combined with their belief that thinness is associated with HIV, places those with T2DM at risk of secondary complications arising from diabetes mellitus, and those without diabetes mellitus at a higher risk of developing T2DM. A discrepancy between PBI and BMI may therefore serve as a risk marker to alert clinicians to use a more ethno-cultural specific approach in engaging with urban Black women regarding weight loss strategies in the future.
