Abstract
Rationale: Intimate partner violence and child maltreatment have been separately associated with asthma in adults. No study has concurrently examined of adulthood adverse events (including, but not limited to, intimate partner violence) and child maltreatment on asthma in adults. Objectives: To concurrently examine of adulthood adverse events and child maltreatment on asthma in adults. Methods: This was a cross-sectional study of adulthood adverse events and child maltreatment on current asthma in 87,891 adults 40-69 years old who participated in the UK Biobank. Adulthood adverse events were assessed using questions adapted from a national crime survey. Child maltreatment was ascertained using the Childhood Trauma Screener questionnaire. Current asthma was defined as physician-diagnosed asthma and current wheeze and was further classified as noneosinophilic or eosinophilic according to eosinophil count (<300 vs. ⩾300 cells per microliter). Results: In a multivariable analysis, participants who reported two or more types of adulthood adverse events had 1.19-1.45 times significantly higher odds of asthma than those who did not, whereas participants who reported two or more types of child maltreatment had 1.25-1.59 significantly higher odds of asthma than those who reported no child maltreatment. After stratification by sex, similar results were obtained for child maltreatment in women and men, whereas adulthood adverse events were only significantly associated with asthma in women. Similar findings were observed in analyses that were restricted to never-smokers and former smokers with <10 pack-years of smoking and in analyses of noneosinophilic and eosinophilic asthma. Conclusions: In a cohort of British adults, child maltreatment was associated with current asthma in men and women, whereas adulthood adverse events were associated with current asthma in women only. This was independent of cigarette smoking or eosinophil count.
