Which health condition is identified with the 20-year trend in the US due to rapid urban industrial workforce expansion?

• A. Asthma
• B. Lung Cancer
• C. Obesity
• D. Hypertension

Answer: (A)

Exposure to air pollutants and irritants in rapidly expanding urban-industrial settings increases the risk of developing and worsening asthma. In cities, higher levels of traffic-related pollution, particulate matter, and indoor allergens can trigger airway inflammation and hyperreactivity, leading to wheezing, coughing, and difficulty breathing. Over a couple of decades, this environmental and occupational exposure pattern tends to rise with urban workforce expansion, making asthma the condition most closely tied to that trend. Lung cancer is more strongly linked to long-term smoking and other carcinogen exposures that accumulate over many years, not specifically to a short-term urban growth pattern. Obesity and hypertension are influenced by metabolic factors, diet, physical activity, and genetics, which don’t connect as directly to rapid urban industrial expansion over a 20-year span.
