Which of the following is a common risk factor for developing type 2 diabetes mellitus?

Advanced age is indeed recognized as a common risk factor for developing type 2 diabetes mellitus. As individuals age, the risk of type 2 diabetes increases due to several physiological changes that occur in the body, such as reduced insulin sensitivity and increased fat accumulation, which can affect glucose metabolism. The aging population also tends to have a higher prevalence of obesity and sedentary lifestyles, further contributing to the risk.

Furthermore, age-related factors, such as the potential for developing other health issues and a relative decrease in physical activity, may make managing weight and glucose levels more challenging. Thus, older adults are at a heightened risk for type 2 diabetes compared to younger individuals.

In contrast, regular exercise typically reduces the risk of developing type 2 diabetes by promoting weight management and enhancing insulin sensitivity. Genetic predisposition can play a role but is often considered in conjunction with lifestyle factors. A low body mass index (BMI) generally indicates a lower risk of type 2 diabetes, as obesity is one of the most significant risk factors for the condition.
