Which of the following is not a risk factor associated with Type 2 diabetes?

Engaging in regular exercise is recognized as a protective factor against Type 2 diabetes rather than a risk factor. Regular physical activity can help maintain a healthy weight, improve insulin sensitivity, and reduce the likelihood of developing Type 2 diabetes. Studies have shown that individuals who engage in consistent exercise tend to have a lower risk of developing this condition because exercise aids in glucose metabolism and contributes to overall health.

In contrast, being over 45 years old, having a family history of diabetes, and being overweight or obese are all established risk factors that can increase the likelihood of developing Type 2 diabetes. These factors are linked to changes in metabolism, hormonal balance, and body composition that predispose individuals to insulin resistance and glucose intolerance. Therefore, regular exercise plays a crucial role in preventing Type 2 diabetes, making it distinct from the other options listed.
