Which factor is considered a primary risk factor for developing asthma?

Family history of asthma or allergies is a primary risk factor for developing asthma due to the hereditary nature of the condition. Asthma can run in families, indicating a genetic predisposition that can increase an individual's likelihood of developing the disease. If one or both parents have asthma or allergies, their children are at a heightened risk, as common genetic and environmental factors play a significant role in the onset of the condition. Understanding this risk helps in identifying individuals who may need early interventions or monitoring for asthma, emphasizing the importance of family medical history in asthma management and prevention strategies.

The other factors mentioned, while they might relate to health in various ways, do not have the same direct correlation with the development of asthma. Age over 60 could indicate other respiratory issues but is not a primary factor for asthma specifically. High cholesterol, primarily associated with cardiovascular issues, does not have a recognized link to the onset of asthma. Strong physical fitness, while beneficial for overall health and asthma management, does not serve as a risk factor for developing the condition itself.
