    Abstract

    Childhood abuse and neglect are traumatic early-life stressors that may be risk factors for central adiposity. Our objective was to examine the association between childhood abuse/neglect and central adiposity and obesity in a sample of 311 women (106 Black, 205 White) from the Pittsburgh site of the Study of Women's Health Across the Nation (SWAN). SWAN included a baseline measurement of women in midlife (mean age = 45.7) and 8 follow-up visits during which waist circumference (WC) and body mass index (BMI) were measured. The Childhood Trauma Questionnaire, given at visit 8, retrospectively assessed 5 domains of abuse and neglect in childhood and adolescence: emotional, physical, and sexual abuse; emotional and physical neglect. ANCOVAs were used to determine whether a history of any abuse/neglect, or each type of abuse or neglect, was associated with WC, controlling for age. Results showed that women with a history of any abuse/neglect had significantly higher WC at visit 8 than women with no abuse history (M = 90.8, SE = 1.2; M = 96.1, SE = 1.5; F(1, 308)= 7.7, p = .01). Of the specific types of abuse, only physical abuse was significantly related to WC at visit 8 (M = 91.7, SE = 1.0; M = 97.9, SE = 2.3; F(1,308)=6.2, p = .01)]. Analyses for the outcome of BMI showed similar results, with the addition of sexual abuse being important for obesity. Histories of any abuse/neglect, or specific types of abuse or neglect, were not associated with increased WC from baseline to visit 8 in the full sample. However, among normal-weight and overweight women, a history of any abuse/neglect, emotional abuse, physical abuse, sexual abuse, or physical neglect predicted increased WC over time. Additional mediation analyses showed that Trait Anger scores mediated some relationships between abuse/neglect and WC. This study suggests that traumatic early-life stressors are associated with adulthood body fat distribution, especially among normal-weight and overweight women.

    Abstract: Childhood abuse and neglect are traumatic early-life stressors that may be risk factors for central adiposity. Our objective was to examine the association between childhood abuse/neglect and central adiposity and obesity in a sample of 311 women (106 Black, 205 White) from the Pittsburgh site of the Study of Women's Health Across the Nation (SWAN). SWAN included a baseline measurement of women in midlife (mean age = 45.7) and 8 follow-up visits during which waist circumference (WC) and body mass index (BMI) were measured. The Childhood Trauma Questionnaire, given at visit 8, retrospectively assessed 5 domains of abuse and neglect in childhood and adolescence: emotional, physical, and sexual abuse; emotional and physical neglect. ANCOVAs were used to determine whether a history of any abuse/neglect, or each type of abuse or neglect, was associated with WC, controlling for age. Results showed that women with a history of any abuse/neglect had significantly higher WC at visit 8 than women with no abuse history (M = 90.8, SE = 1.2; M = 96.1, SE = 1.5; F(1, 308)= 7.7, p = .01). Of the specific types of abuse, only physical abuse was significantly related to WC at visit 8 (M = 91.7, SE = 1.0; M = 97.9, SE = 2.3; F(1,308)=6.2, p = .01)].
