Abstract:
ObjectiveTo investigate the association of long-term changes in body mass index, waist circumference, and waist-to-height ratio with the risk of type 2 diabetes mellitus in the older population.MethodsWe conducted a prospective cohort study in Jiangsu Province, China. Data from 593 participants who were aged ≥60 years were analyzed. The hazard ratios and 95% confidence intervals were estimated using the Cox proportional hazards model.ResultsOver a median follow-up period of 5.08 years, 70 participants (11.80%) developed type 2 diabetes mellitus. Compared with participants with persistently normal body mass index, waist circumference, and waist-to-height ratio, those in whom these parameters changed from normal to abnormal and those in whom these parameters were persistently abnormal had a significantly higher risk of type 2 diabetes mellitus, with adjusted hazard ratios of 2.11 (95% confidence interval: 1.05-4.26) and 2.37 (95% confidence interval: 1.21-4.63) for body mass index, 2.75 (95% confidence interval: 1.16-6.51) and 2.32 (95% confidence interval: 1.29-4.16) for waist circumference, and 2.24 (95% confidence interval: 1.14-5.91) and 4.11 (95% confidence interval: 2.21-7.68) for waist-to-height ratio, respectively.ConclusionLong-term changes in obesity-related anthropometric indicators are strongly associated with the risk of type 2 diabetes mellitus in the older population.

Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
