Which is a significant risk factor for developing allergic rhinitis?

A significant risk factor for developing allergic rhinitis is a history of atopic disease. Atopic diseases include conditions such as asthma, eczema, and other allergic conditions that are often related to an individual's predisposition to allergic reactions. This is primarily due to genetic and environmental factors that influence the immune system's response to allergens.

Individuals with a history of atopic disease have a greater likelihood of developing multiple allergic conditions, including allergic rhinitis. This is because atopy involves an exaggerated immune response to commonly harmless substances, leading to a higher sensitivity to allergens like pollen, dust mites, and pet dander, which are known triggers for allergic rhinitis. In essence, a history of atopic disease signifies a person’s tendency to develop allergies, making it a key risk factor for this condition.

In contrast, age, history of hypertension, and family history of diabetes do not have the same direct correlation with the development of allergic rhinitis. While age can influence the prevalence of certain allergies due to immune system maturation or changes, it is not as strong a predictor as atopic disease history. Hypertension and diabetes relate more to metabolic and cardiovascular conditions rather than allergic responses, thus making them less relevant in the context of allergic rhinitis.
