Childhood physical, sexual, and emotional abuse are linked to adult obesity, and little is known about what protective factors might mitigate this association.
Data from female (n=4,247) and male (n=1,982) participants in the longitudinal Growing Up Today cohort study from 1996 to 2013 were used to examine whether factors found to promote mental health resilience after abuse also operate as buffers (modifiers) of the abuse-weight status association. At ages 20-25 years, participants were asked about their history of child abuse before age 18 years. Potential resilience factors (modifiers) included childhood family SES, neighborhood safety, supportive relationships with adult nonfamily members, quality of maternal relationship, family structure, religious service attendance, and prayer/meditation. Associations between child abuse and BMI at ages 25-32 years were modeled using linear regression, adjusted for sociodemographic variables and baseline BMI. Potential modifiers were tested with interaction terms. Analyses were run in 2019-2020.
Severe abuse was associated with 0.9 kg/m (95% CI=0.5, 1.2) higher adult BMI than no abuse, corresponding to a 46% increased risk of obesity (95% CI=1.28, 1.67). Less severe abuse was not significantly associated with BMI (β=0.1, 95% CI= -0.2, 0.4). There were no significant interactions between modifiers and abuse.
Factors previously found to promote resilience to mental health sequelae after abuse did not modify the association of severe child abuse with higher weight status.
儿童期身体、性和情感虐待与成人肥胖有关，但对于哪些保护因素可能减轻这种关联知之甚少。
使用 1996 年至 2013 年纵向“今日成长”队列研究中女性（n=4247）和男性（n=1982）参与者的数据，来检验在遭受虐待后促进心理健康复原力的因素是否也作为（调节）虐待与体重状况关联的缓冲器。在 20-25 岁时，参与者被问及他们在 18 岁之前的儿童期虐待史。潜在的复原力因素（调节因素）包括儿童期家庭社会经济地位、邻里安全、与成年非家庭成员的支持性关系、与母亲关系的质量、家庭结构、参加宗教服务和祈祷/冥想。使用线性回归模型来拟合儿童期虐待与 25-32 岁时 BMI 的关联，调整了社会人口统计学变量和基线 BMI。使用交互项来检验潜在的调节因素。分析于 2019-2020 年进行。
严重虐待与成人 BMI 高 0.9kg/m（95%CI=0.5, 1.2）有关，肥胖风险增加 46%（95%CI=1.28, 1.67）。较轻的虐待与 BMI 无显著相关性（β=0.1，95%CI=-0.2, 0.4）。调节因素与虐待之间没有显著的相互作用。
先前发现促进虐待后心理健康后果复原力的因素并未改变严重儿童虐待与更高体重状况之间的关联。
