**Question:** All are risk factors for type 2 diabetes mellitus that warrant early screening for diabetes except

A. Age
B. Gender
C. Obesity
D. Smoking

**Correct Answer:** B. Gender

**Core Concept:** Type 2 Diabetes Mellitus (T2DM) is a chronic condition characterized by impaired glucose tolerance and insulin resistance. Risk factors for T2DM include age, obesity, smoking, and a family history of diabetes. Early screening can help identify individuals at risk and initiate preventive measures or early treatment.

**Why the Correct Answer is Right:** Gender, specifically being a woman, is not considered a risk factor for T2DM compared to men. Women may develop T2DM after menopause due to hormonal changes, but this does not qualify as a risk factor during pre-menopausal years.

**Why Each Wrong Option is Incorrect:**

A. Age (C) is a strong risk factor for T2DM as glucose tolerance declines with age, leading to increased susceptibility to diabetes.

B. Gender (D) is incorrect because being male is a risk factor, whereas women are at risk during menopause.

C. Obesity (C) is a major risk factor for T2DM, as excess body fat contributes to insulin resistance and glucose intolerance.

D. Smoking (D) is a risk factor for T2DM, as it leads to insulin resistance, inflammation, and endothelial dysfunction.

**Clinical Pearl:** Early identification of individuals with multiple risk factors and a family history of diabetes is crucial for preventive measures and timely management. While age, obesity, and smoking contribute to the development of T2DM, gender as a risk factor is limited to specific age groups and circumstances (menopause in women). This emphasizes the importance of considering individual patient characteristics and circumstances when assessing diabetes risk.
