Background: Asthma is associated with low socioeconomic status among both children and adults, and adolescents with asthma report more school absenteeism than those without. However, it is unclear whether asthma in childhood and adolescence affects socioeconomic status in adulthood.
Methods: Within the Obstructive Lung disease In Northern Sweden Studies, all children in grade 1 and 2 in three municipalities were invited to a questionnaire survey, 97% participated (n = 3430). They were followed annually until age 19, and thereafter at age 28 years. In this study, participants at ages 8 y, 12 y, 19 y and 28 y (n = 2017) were included. Asthma was categorized into childhood onset (up to age 12 y) and adolescent onset (from 12 to 19 y). Data for assessment of socioeconomic status was collected at 28 y and included educational level, occupation, and occupational exposure to gas, dust and/or fumes (GDF).
Results: Childhood onset asthma was associated with having compulsory school as the highest educational level at age 28 y, also after adjustment for sex, smoking and BMI at age 19 y and socioeconomic factors in childhood (OR 4.84 95%CI 2.01–11.65), and the pattern was the same among men and women. However, we found no significant associations between asthma in childhood or adolescence and socioeconomic groups, occupational groups or occupational exposure to GDF at age 28 y.
Conclusions: Even though asthma in high-income countries, such as Sweden, is well recognised and treated, this study highlight that childhood onset asthma may have a negative long-term effect with regard to educational level in young adulthood.
