Adult-onset asthma is associated with higher odds of comorbidities such as obesity, dyslipidemia, arthritis, and diabetes compared to childhood-onset asthma. Older age of asthma diagnosis is associated with higher odds of diabetes and hypertension, while younger age of asthma diagnosis is associated with higher odds of chronic obstructive pulmonary disease.
Background: Age of asthma onset has emerged as an important determinant of asthma phenotypes; however, the comorbidities that predominate in either childhood- or adult-onset asthma are not known.Objective: To identify comorbidities associated with adult-onset asthma vs childhood-onset asthma and with age of asthma diagnosis.Methods: We analyzed data on 27,437 adult participants in the National Health and Nutrition Examination Surveys conducted from 2001 to 2018. Logistic regression adjusted for covariates was used to identify comorbidities associated with the asthma phenotypes and age of asthma diagnosis.Results: Approximately 12.6% of participants were ever diagnosed with asthma; the prevalence of childhoodonset (before 18 years old) and adult-onset (>= 18 years old) current asthma was 2.7% and 5.5%, respectively. After adjustment for covariates including age, adult-onset asthma was associated with higher odds of obesity (odds ratio [OR], 1.46; 95% confidence interval [CI], 1.09-1.96), hypercholesterolemia (OR, 1.67; 95% CI, 1.082.56), borderline high serum triglycerides (OR, 1.78; 95% CI, 1.17-2.71), and osteoarthritis (OR, 1.52; 95% CI, 1.042.20) than was childhood-onset asthma. Older age of asthma diagnosis (per 5-year increase) was also associated with higher odds of diabetes (OR, 1.04; 95% CI, 1.00-1.07) and hypertension (OR, 1.05; 95% CI, 1.02-1.07), whereas younger age of asthma diagnosis was associated with higher odds of chronic obstructive pulmonary disease (OR, 1.12; 95% CI, 1.04-1.19).Conclusion: Age- and covariates-adjusted prevalence of obesity, dyslipidemia, arthritis, diabetes, and hypertension is higher in adult-onset asthma than in childhood-onset asthma, and with older age of asthma diagnosis. Conversely, the prevalence of chronic obstructive pulmonary disease increases with younger age of asthma diagnosis. (c) 2022 American College of Allergy, Asthma & Immunology.
