OBJECTIVE: We examined the associations between obesity-related indices and the risk of diabetes progression from prediabetes in older adults, comparing the differences in using the American Diabetes Association (ADA) and World Health Organization (WHO) criteria.
METHODS: Data were obtained from the Healthy Aging Evaluation Longitudinal Study conducted in China. At baseline, prediabetes (in participants without diabetes) was classified based on fasting plasma glucose (FPG) levels using both criteria. Body mass index (BMI) and waist circumference (WC) were categorized according to data distribution and diagnostic cut-off values, respectively. Cox proportional hazards regression models were used to estimate the adjusted hazard ratios ( aHRs) with 95% confidence intervals ( CIs) for obesity-related indices and diabetes progression from prediabetes.
RESULTS: Among the 1,127 participants classified as prediabetic according to the ADA criteria, 474 met the WHO criteria. Under ADA-defined prediabetes, the highest WC quartile (≥ 93 cm) was significantly associated with an increased diabetes risk ( aHR 1.93 [1.06, 3.53, P < 0.05]), whereas BMI-related and cut-off-based abdominal obesity demonstrated no significant associations ( P > 0.05). Under WHO-defined prediabetes, both the high tertile of WC (≥ 90 cm) and general obesity (BMI ≥ 28.0 kg/m 2) were significantly associated with progression to diabetes ( P < 0.05), with aHR 2.13 (1.06, 4.27) and 2.44 (1.19, 5.01), respectively. However, cut-off-based abdominal obesity and the high BMI tertile (≥ 25.75 kg/m 2) were not significantly associated with diabetes progression ( P > 0.05).
CONCLUSION: Elevated WC, rather than BMI-based indices or cut-off-based abdominal obesity, was significantly associated with diabetes progression according to the ADA-defined prediabetes criteria. However, both the evaluated WC and general obesity predicted progression to diabetes according to the WHO criteria.
