Following is not a risk factor for development of diabetes mellitus
**Core Concept**
Diabetes mellitus is a complex metabolic disorder influenced by genetic, environmental, and lifestyle factors. Understanding the risk factors is crucial for early diagnosis and prevention of the disease.
**Why the Correct Answer is Right**
The correct answer will be one of the options that does not contribute to the development of diabetes mellitus. Each option must be evaluated based on its relationship to diabetes. For instance, obesity (A) is a well-established risk factor for type 2 diabetes due to insulin resistance. Similarly, family history (B) increases the risk, as genetic factors play a significant role in the development of diabetes. However, physical activity (C) is generally considered a protective factor against developing diabetes, as regular exercise improves insulin sensitivity.
**Why Each Wrong Option is Incorrect**
**Option A:** Obesity is a significant risk factor for type 2 diabetes, as it leads to insulin resistance and pancreatic beta-cell dysfunction.
**Option B:** A family history of diabetes increases the risk of developing the disease, as genetic factors contribute to the pathogenesis.
**Option D:** (Assuming this is the correct answer) Physical activity, such as regular exercise, is a protective factor against developing diabetes, as it improves insulin sensitivity and glucose metabolism.
**Clinical Pearl / High-Yield Fact**
It's essential to note that physical activity, along with a healthy diet, can help prevent or delay the onset of type 2 diabetes in individuals at risk.
**Correct Answer:** C. Physical activity is generally considered a protective factor against developing diabetes.
