Which of the following is NOT a risk factor for developing asthma?

Obesity is often associated with various health risks, including the development of asthma, rather than being a non-risk factor. In fact, numerous studies indicate that overweight and obese individuals have a higher prevalence of asthma. This correlation may be due to several physiological mechanisms, such as inflammation, reduced lung function, and increased respiratory impairment associated with excess body weight.

In contrast, younger age, African American race, and female gender are recognized risk factors for developing asthma. Younger individuals often have more reactive airways, African American individuals can face genetic factors and environmental exposures that heighten asthma risk, and females, particularly during puberty and adulthood, may experience hormonal influences that can contribute to the development and exacerbation of asthma. Thus, identifying the correct non-risk factor involves understanding the broader epidemiological context of asthma risks, which highlights that obesity does indeed increase the likelihood of developing asthma rather than negates it.
