Prevalence and Risk Factors of Asthma, Rhinitis, and Eczema and Their Multimorbidity among Young Adults in Kuwait: A Cross-Sectional Study

Abstract EN

Objective.

To estimate the prevalence of allergic diseases and allergic multimorbidity (coexistence) among young adults in Kuwait and to examine associations between risk factors with allergic diseases and allergic multimorbidity.

Methods.

A cross-sectional study was conducted by enrolling 1,154 students, aged 18–26 years, attending Kuwait University.

Participants self-completed a questionnaire on symptoms and clinical history of allergic diseases.

Prevalence ratios (PRs) and 95% confidence intervals (CIs) were estimated by applying Poisson regression with robust variance estimation.

Results.

The prevalence of current asthma, rhinitis, and eczema was estimated to be 11.9% (135/1135), 20.4% (232/1138), and 9.2% (105/1143), respectively.

The coexistence of “asthma and rhinitis” (5.1%, 57/1125) was the most frequent allergic multimorbidity.

Both maternal history (PR = 3.97, 95% CI: 2.32–6.80) and paternal history (PR = 1.72, 95% CI: 1.10–2.68) of allergy were independently associated with having two or more coexisting allergic diseases.

The joint effect of having both maternal and paternal history of allergy was associated with 8.16 times (95% CI: 4.19–15.90) higher risk of allergic multimorbidity.

Conclusion.

Allergic diseases and allergic multimorbidity are common among young adults in Kuwait and their burden mirrors that of westernized countries.

Parental history of allergy is a strong predisposing factor for allergic multimorbidity.
