Background: Although chronic spontaneous urticaria (CSU) affects all age groups, data regarding CSU in adolescents is scarce. Objective: To characterize the epidemiology, demographics, and comorbidities associated with CSU in a large, cross-sectional nationwide population of adolescents. Methods: Medical records of 16-year-old candidate conscripts to the Israeli Defense Forces were reviewed. Data were collected on the prevalence and severity of CSU, as well as the demographics, medical comorbidities, medication use, and blood test results of affected individuals. Results: Medical records of 1,108,833 consecutive 16-year-old adolescents were reviewed. A total of 6617 (0.6%) adolescents received CSU diagnoses. CSU was increased in female conscripts (odds ratio [OR] 1.13, 95% confidence interval [CI] 1.07-1.19, P < .001) and adolescents with higher socioeconomic scores (OR 1.92, 95% CI 1.56-2.32, P < .001). Individuals with CSU were significantly more likely to have allergic diseases, including food allergy (OR 7.31, 95% CI 6.13-8.72), allergic rhinitis (OR 2.9, 95% CI 2.71-3.11), atopic dermatitis (OR 2.35, 95% CI 2.03-2.72), and asthma (OR 1.46, CI 1.35-1.57). Conclusion: Our work provides an account of CSU in a large cohort of adolescents. We found a strong link between CSU and atopic diseases. Further investigation is needed to decipher the mechanism underlying this observed association.
