People who experienced sexual abuse as children and later develop postpartum depression are four times more likely to have antibodies attacking their thyroid and twice as likely to have thyroid dysfunction. This finding is from the abstract summary - full study details were not available.

Stress & Thyroid Function - From Bench to Bedside.
This study found that women who were sexually abused as children are twice as likely to have thyroid problems and four times more likely to have antibodies attacking their thyroid, especially if they get depressed after having a baby. This suggests early trauma can mess with the thyroid long after the abuse happened.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
A systematic review and meta-analysis of longitudinal studies could determine whether childhood sexual abuse consistently predicts thyroid autoantibody development and dysfunction across diverse populations, adjusting for depression, socioeconomic status, and genetic risk.
A systematic review and meta-analysis of prospective cohort studies including at least 15,000 individuals with verified childhood sexual abuse history and 30,000 matched controls, with standardized thyroid antibody testing (TPOAb, TgAb) and thyroid function assessments over 15+ years, stratified by postpartum depression status.
An RCT cannot ethically test childhood trauma exposure, but could test whether interventions reducing depression in trauma survivors alter thyroid autoimmunity progression.
A double-blind RCT of 300 women with childhood sexual abuse history and postpartum depression, randomized to 12 weeks of trauma-focused cognitive behavioral therapy vs. supportive counseling, measuring changes in TPOAb titers and TSH levels as primary endpoints.
A prospective cohort study could determine whether childhood sexual abuse predicts the development of thyroid autoantibodies years before clinical dysfunction appears.
A prospective cohort study following 10,000 women from adolescence into postpartum period, with documented childhood trauma history, measuring TPOAb and TSH annually from age 18 to 35, with detailed psychiatric assessments at each visit.
A case-control study could compare the prevalence of childhood sexual abuse in women with postpartum depression and elevated TPOAb versus those with postpartum depression but normal antibodies.
A matched case-control study comparing 400 women with postpartum depression and elevated TPOAb (>35 IU/mL) to 400 women with postpartum depression and normal TPOAb, using validated trauma interviews to assess childhood sexual abuse history.
A cross-sectional study could identify whether women with postpartum depression and elevated thyroid antibodies report higher rates of childhood sexual abuse than those without antibodies.
A cross-sectional survey of 2,000 postpartum women measuring TPOAb levels and using validated trauma questionnaires (e.g., CTQ) to assess childhood sexual abuse history, with adjustment for age, parity, and depression severity.
