The impact of adverse childhood experiences on the health and health behaviors of young Australian women

Background: Adverse childhood experiences have been linked to poor health and adverse health behavior in adulthood. Objective: This study aimed to estimate the prevalence of adverse childhood experiences among young Australian women (aged 20-25) and examine associations between adverse childhood experiences and adult health behaviors and physical and mental health. Participants and Settings: Data were from the 1989 95 cohort of the Australian Longitudinal Study on Women's Health, who completed the Adverse Childhood Experiences Scale at Survey 3 in 2015 (N = 8609). Methods: Outcomes included: self-rated health, sexual health, psychological distress, depression, anxiety, suicide ideation, self-harm, substance abuse (drinking, smoking, illicit drugs), severe obesity, and exercise. Prevalence of childhood adversities were presented, with the association between childhood adversity and outcomes evaluated using log-binomial multivariable regressions (99% CI). Results: While 59% of women reported experiencing at least one childhood adversity, 10% of participants reported adverse childhood experiences across four or more categories, indicating a significant burden of risk for young Australian women. Women reporting four or more categories had higher rates of poor physical health (adjPR = 1.79, 99% CI = 1.51-2.12), sexually transmitted infections (adjPR = 1.36, 99% CI = 1.11-1.67), and poor mental health (adjPR = 2.78, 99% CI = 2.34-3.32), and increased rates of severe obesity (adjPR = 2.14, 99% CI = 1.61-2.86) and smoking (adjPR = 2.23, 99% CI = 1.89-2.64). Conclusion: Using nationally representative data, this study shows adverse childhood experiences directly impact physical and mental health, and health behaviors in adulthood among young Australian women. The management of health and wellbeing in adulthood should look beyond the contemporaneous factors, incorporating a focus on how childhood adversity may negatively influence health behavior, health and wellbeing in later life.
