This study tested whether dating violence (DV) victimization is associated with increases in BMI across the transition from adolescence to young adulthood and whether gender and previous exposure to child maltreatment modify such increases.
Data were from participants (N = 9295; 49.9% female) in the National Longitudinal Study of Adolescent Health. BMI was calculated from measured height and weight at waves 2, 3, and 4 of the study. DV victimization was measured at waves 2, 3, and 4 by using items from the revised Conflict Tactics Scales. Linear regression by using generalized estimating equations with robust SEs was used to test the association. Models were stratified according to gender and history of child maltreatment.
From baseline to wave 4, BMI increased on average 6.5 units (95% confidence interval [CI]: 6.2-6.7) and 6.8 units (95% CI: 6.5-7.1) among men and women, respectively, and nearly one-half (45.5% of men; 43.9% of women) reported DV at some point. In stratified models, DV victimization (β: 0.3 [95% CI: 0.0-0.6]) independently predicted BMI increase over time in women. Exposure to childhood sexual abuse magnified the increase in BMI associated with DV victimization (β: 1.3 [95% CI: 0.3-2.3]). No other types of childhood maltreatment were significant modifiers of the DV-BMI association. Violence victimization was not associated with BMI among men.
Screening and support for DV victims, especially women who have also experienced childhood maltreatment, may be warranted to reduce the likelihood of health consequences associated with victimization.
本研究旨在检验约会暴力（DV）受害经历是否与从青春期到青年期过渡阶段的体重指数（BMI）增加有关，以及性别和既往儿童期受虐经历是否会改变这种增加情况。
数据来自青少年健康全国纵向研究的参与者（N = 9295；49.9%为女性）。BMI根据研究第2、3、4轮测量的身高和体重计算得出。DV受害经历在第2、3、4轮通过使用修订后的冲突策略量表中的项目进行测量。采用带有稳健标准误的广义估计方程进行线性回归以检验这种关联。模型根据性别和儿童期受虐史进行分层。
从基线到第4轮，男性和女性的BMI分别平均增加6.5个单位（95%置信区间[CI]：6.2 - 6.7）和6.8个单位（95% CI：6.5 - 7.1），近一半（45.5%的男性；43.9%的女性）在某个时间点报告有DV经历。在分层模型中，DV受害经历（β：0.3 [95% CI：0.0 - 0.6]）独立预测女性随时间的BMI增加。童年期遭受性虐待会放大与DV受害经历相关的BMI增加（β：1.3 [95% CI：0.3 - 2.3]）。其他类型的童年期受虐并非DV与BMI关联的显著调节因素。暴力受害经历与男性的BMI无关。
对DV受害者，尤其是那些也经历过童年期受虐的女性进行筛查和提供支持，可能有助于降低与受害经历相关的健康后果发生的可能性。
