Which factor is associated with obesity?

• A. Age
• B. Hypertension
• C. Diabetes
• D. Tobacco use

Answer: (D)

Obesity is most often linked to factors that influence long-term weight balance and metabolic health, such as aging, higher blood pressure, and insulin resistance leading to conditions like diabetes. The relationship among these factors helps explain why obesity often clusters with cardiovascular and metabolic risks. Tobacco use, however, does not fit as a typical driver of obesity. Nicotine can suppress appetite and raise metabolic rate, so smokers tend to have lower body weight, and weight gain is more commonly seen after quitting rather than during ongoing tobacco use. So, in the context of factors commonly associated with obesity, tobacco use does not align as a contributing factor, whereas age and metabolic-related conditions like hypertension and diabetes do.
