Which group of people is most likely to develop asthma?

Children, especially those with a family history of allergies, are indeed the group most likely to develop asthma. This is largely due to the interplay of genetic, environmental, and immunological factors. Asthma often develops in childhood, and children with a family history of atopic conditions, like allergies and asthma themselves, have a heightened risk of developing the disease.

The reason family history plays such a crucial role is that asthma has a significant hereditary component. Genetic predispositions can affect the immune system’s response to allergens, leading to increased susceptibility to asthma. Exposure to allergens such as dust mites, pollen, pet dander, and certain foods can trigger asthma symptoms in those who are genetically predisposed.

While adults and the elderly can also develop asthma, especially due to factors such as occupational exposure or respiratory infections, the initial onset of asthma symptoms commonly occurs in childhood. Ethnic background, exposure to tobacco smoke, and urban living also contribute to the likelihood of asthma in children.
