Sex-specific relationships between adverse childhood experiences and chronic obstructive pulmonary disease in five states

Purpose: Adverse childhood experiences (ACEs) before age 18 have been repeatedly associated with several chronic diseases in adulthood such as depression, heart disease, cancer, diabetes, and stroke. We examined sex-specific relationships between individual ACEs and the number of ACEs with chronic obstructive pulmonary disease (COPD) in the general population. Materials and methods: Data from 26,546 women and 19,015 men aged >= 18 years in five states of the 2011 Behavioral Risk Factor Surveillance System were analyzed. We used log-linear regression to estimate prevalence ratios (PRs) and their corresponding 95% confidence intervals (CIs) for the relationship of eight ACEs with COPD after adjustment for age group, race/ethnicity, marital status, educational attainment, employment, asthma history, health insurance coverage, and smoking status. Results: Some 63.8% of women and 62.2% of men reported >= 1 ACE. COPD was reported by 4.9% of women and 4.0% of men. In women, but not in men, there was a higher likelihood of COPD associated with verbal abuse (PR = 1.30, 95% CI: 1.05, 1.61), sexual abuse (PR = 1.69, 95% CI: 1.36, 2.10), living with a substance abusing household member (PR = 1.49, 95% CI: 1.23, 1.81), witnessing domestic violence (PR = 1.40, 95% CI: 1.14, 1.72), and parental separation/divorce (PR = 1.47, 95% CI: 1.21, 1.80) during childhood compared to those with no individual ACEs. Reporting >= 5 ACEs (PR = 2.08, 95% CI: 1.55, 2.80) compared to none was associated with a higher likelihood of COPD among women only. Conclusion: ACEs are related to COPD, especially among women. These findings underscore the need for further research that examines sex-specific differences and the possible mechanisms linking ACEs and COPD. This work adds to a growing body of research suggesting that ACEs may contribute to health problems later in life and suggesting a need for program and policy solutions.
