目的儿童虐待增加肥胖的风险，但虐待类型的差异影响尚不清楚。皮质醇反应性可能有助于澄清这些影响，皮质醇反应性，虐待和肥胖之间的联系。我们研究了这些协会在男孩和女孩在整个adolescence.MethodsWe收集的数据从454青少年（212名女孩）在四个波（年龄8-13岁的时间1），包括303虐待青年。我们建模的身体质量指数（BMI）百分位数的轨迹分别按年龄排列的男孩和女孩，并测试是否皮质醇反应在时间1缓和虐待类型和BMI growth.ResultsIn女孩之间的关联，皮质醇反应缓和虐待类型和BMI的二次变化之间的关联。在皮质醇水平较低的情况下，与对照组（-0.65，95%置信区间[CI]-1.09至-0.22）和身体虐待组（-0.76，95%CI-1.29，-0.24）相比，性虐待组女孩的BMI呈二次曲线型增长。在高水平的皮质醇下，性虐待女孩与对照组（0.15，95% CI-0.40至0.70）或身体虐待（0.21，95% CI-0.38至0.80）女孩在BMI的二次变化方面没有差异。在男孩中，皮质醇反应性没有缓和虐待类型和BMI growth.ConclusionsThe组合较低的皮质醇反应性和性虐待可能会把女孩在青春期后期的BMI增加的风险之间的关联。鉴于高BMI的负面影响，识别和干预这些女孩可能会导致这一群体更好的健康和福祉。皮质醇反应性在男孩中可能不起同样的作用。
PurposeChild maltreatment increases risk for obesity, yet differential effects of maltreatment type remain unclear. Cortisol reactivity may help clarify these effects, given links among cortisol reactivity, maltreatment, and obesity. We examined these associations in boys and girls across adolescence.MethodsWe collected data from 454 adolescents (212 girls) across four waves (aged 8–13 years at Time 1), including 303 maltreated youth. We modeled body mass index (BMI) percentile trajectories arrayed by age separately for boys and girls and tested whether cortisol reactivity at Time 1 moderated the association between maltreatment type and BMI growth.ResultsIn girls, cortisol reactivity moderated the association between maltreatment type and quadratic change in BMI. At low levels of cortisol, sexually abused girls had a steeper quadratic increase in BMI compared with comparison (−.65, 95% confidence interval [CI] −1.09 to −.22) and physically abused (−.76, 95% CI −1.29, −.24) girls. At high levels of cortisol, sexually abused girls did not differ from comparison (.15, 95% CI −.40 to .70) or physically abused (.21, 95% CI −.38 to .80) girls in quadratic change in BMI. In boys, cortisol reactivity did not moderate the association between maltreatment type and BMI growth.ConclusionsThe combination of lower cortisol reactivity and sexual abuse may put girls at risk for BMI increase during later adolescence. Given the negative consequences of high BMI, identifying and intervening with these girls could lead to better health and well-being among this group. Cortisol reactivity may not play the same role among boys.
