Weight Loss Trajectories and Adverse Childhood Experience among Obese Adolescents with Polycystic Ovary Syndrome

Study Objective: To examine the effect of childhood trauma and family history of psychiatric illness on weight loss trajectories of obese, female adolescents with polycystic ovary syndrome (PCOS). Design: Prospective study. Setting: PCOS and adolescent medicine outpatient clinics. Participants: Participants were, on average, 15.8 years of age, 80% Caucasian (39/49 participants), and had a body mass index of 36.8 +/- 8.8. Interventions: Healthy Bodies, Healthy Minds is an evidence-based one-on-one intervention consisting of 4 weekly sessions, 4 biweekly sessions, and 3 monthly booster sessions. Each session was 45-60 minutes long with 15-30 minutes of physical activity with a lifestyle coach. Main Outcome Measures: Paired sample t tests were used to assess group differences in pre-and post-treatment weight between participants reporting childhood trauma and body mass index-matched controls not endorsing trauma. One-way analysis of variance was performed to assess the influence of childhood trauma on weight loss between the 2 groups. Results: Adolescents without a family history of psychiatric illness lost more weight (mean, -1.28 kg; SD, 6.89) than those who had a family history of psychiatric illness(mean, -0.64 kg; SD, 4.7) frombaseline to booster sessioncompletion (6months). However, results of independent t tests did not reveal statistically significant group differences in weight loss from baseline to booster session completion (t(21) = 0.51; P= .6). Conclusion: Obese adolescents with PCOS who have experienced childhood trauma can lose weight and acquire its health benefits when enrolled in an intervention addressing weight, mood, and sleep. Family history of psychiatric illness emerged as a potential predictor of lesser weight loss.
