In the material, older age is associated with which risk factor?

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

Answer: (B)

Older age showing a link to tobacco use reflects how cumulative exposure and cohort patterns shape risk. In many datasets, people born earlier grew up in a time when smoking was far more common, so the older groups have higher rates of tobacco use. The harm from tobacco compounds over years of use, so with increasing age you see the consequences and continuation of smoking history. This pattern makes tobacco use the risk factor most strongly associated with older age in the material, highlighting how historical smoking prevalence and longer duration of use contribute to the observed age-related association. While other risk factors can rise with age due to aging physiology, the material specifically emphasizes tobacco use as the age-linked factor here.
