Introduction: Evidence consistently links obesity-related traits with type 2 diabetes (T2D) [1], [2]. However, the contribution of different body composition markers to the development of T2D is unclear. The studies were limited to only some anthropometric marker, small samples sizes and short follow-up periods <1 and 2 year [3], [4]. Therefore, we investigated the associations of body composition markers derived from different entities including bioelectrical impedance analyses (BIA) and magnetic resonance imaging (MRI) with changes in glucose metabolism and with incident T2D.
Method: We used data from 2,333 individuals of the TREND-0 and TREND-1 a population-based study of health in Pomerania (SHIP) with a median follow-up of 7.3 years. The design of the SHIP study has been described previously [5]. Standardized changes in body composition markers were related to changes in fasting glucose, 2-hour post-load glucose, glycated hemoglobin (HbA1c), and estimated glucose disposal rate by linear regressions adjusted for confounder at baseline age, sex, smoking, physical activity, follow-time and mean of the baseline and follow-up outcome values. Associations of body composition markers with incident T2D were investigated by poisson regression models using the same adjustment at baseline and follow-up time.
Results: Waist circumference, waist-to-height ratio, relative body fat, relative fat-free mass, absolute fat-free mass, body cell mass and visceral adipose tissue were strongly associated with incident T2D in both men and women. Similarly, we observed strong positive associations of change in BMI, body weight, waist circumference and hip circumference with continuous markers of glucose metabolism and HbA1c in both men and women . For instance, a one standard deviation higher BMI was associated with a 0.37 mmol/L 95% confidence interval (CI) (0.23 to 0.52) higher 2-hour glucose in men and a 0.24 mmol/L 95% CI (0.12 to 0.35) higher in women respectively. Similarly, one standard deviation higher body weight was associated with 0.34 mmol/L 95% CI (0.21 to 0.47) 2-hour glucose in men and 0.23 mmol/L 95% CI (0.10 to 0.35) in women.
Overall, the associations were more pronounced in men compared to women. Changes in anthropometric markers showed inverse associations with the estimated glucose disposal rate.
Conclusion: Our study indicates the importance of anthropometric, body composition and fat distribution markers as a risk factor for the development of T2D. Our findings indicate that measures against the obesity pandemic has to be introduced to prevent future T2D events.
