National estimates of teen dating violence (TDV) reveal high rates of victimization among high school populations. The Centers for Disease Control and Prevention's national Youth Risk Behavior Survey has provided often-cited estimates of physical TDV since 1999. In 2013, revisions were made to the physical TDV question to capture more serious forms of physical TDV and to screen out students who did not date. An additional question was added to assess sexual TDV.
To describe the content of new physical and sexual TDV victimization questions first administered in the 2013 national Youth Risk Behavior Survey, to share data on the prevalence and frequency of TDV (including the first-ever published overall "both physical and sexual TDV" and "any TDV" national estimates using these new questions), and to assess associations of TDV experience with health-risk behaviors.
DESIGN, SETTING, AND PARTICIPANTS: Secondary data analysis of a cross-sectional survey of 9900 students who dated, from a nationally representative sample of US high school students, using the 2013 national Youth Risk Behavior Survey.
Two survey questions separately assessed physical and sexual TDV; this analysis combined them to create a 4-level TDV measure and a 2-level TDV measure. The 4-level TDV measure includes "physical TDV only," "sexual TDV only," "both physical and sexual TDV," and "none." The 2-level TDV measure includes "any TDV" (either or both physical and sexual TDV) and "none." Sex-stratified bivariate and multivariable analyses assessed associations between TDV and health-risk behaviors.
In 2013, among students who dated, 20.9% of female students (95% CI, 19.0%-23.0%) and 10.4% of male students (95% CI, 9.0%-11.7%) experienced some form of TDV during the 12 months before the survey. Female students had a higher prevalence than male students of physical TDV only, sexual TDV only, both physical and sexual TDV, and any TDV. All health-risk behaviors were most prevalent among students who experienced both forms of TDV and were least prevalent among students who experienced none (all P < .001).
The 2013 TDV questions allowed for new prevalence estimates of TDV to be established that represent a more complete measure of TDV and are useful in determining associations with health-risk behaviors among youth exposed to these different forms of TDV.
全国青少年约会暴力（TDV）估计数显示，高中学生群体中的受害率很高。自1999年以来，疾病控制和预防中心的全国青少年风险行为调查提供了经常被引用的身体TDV估计数。2013年，对身体TDV问题进行了修订，以捕捉更严重形式的身体TDV，并筛选出没有约会的学生。还增加了一个问题来评估性TDV。
描述2013年全国青少年风险行为调查首次使用的新的身体和性TDV受害问题的内容，分享TDV的患病率和频率数据（包括首次公布的使用这些新问题的“身体和性TDV”以及“任何TDV”的全国总体估计数），并评估TDV经历与健康风险行为之间的关联。
设计、背景和参与者：对来自美国高中生全国代表性样本的9900名有约会经历的学生进行横断面调查的二次数据分析，使用2013年全国青少年风险行为调查。
两个调查问题分别评估身体和性TDV；本分析将它们合并以创建一个4级TDV测量指标和一个2级TDV测量指标。4级TDV测量指标包括“仅身体TDV”、“仅性TDV”、“身体和性TDV都有”以及“无”。2级TDV测量指标包括“任何TDV”（身体TDV或性TDV或两者都有）和“无”。按性别分层的双变量和多变量分析评估了TDV与健康风险行为之间的关联。
2013年，在有约会经历的学生中，20.9%的女学生（95%CI，19.0%-23.0%）和10.4%的男学生（95%CI，9.0%-11.7%）在调查前12个月内经历了某种形式的TDV。女学生在仅身体TDV、仅性TDV、身体和性TDV都有以及任何TDV方面的患病率高于男学生。所有健康风险行为在经历两种形式TDV的学生中最为普遍，在没有经历任何TDV的学生中最为少见（所有P＜0.001）。
2013年的TDV问题使得能够建立新的TDV患病率估计数，这些估计数代表了对TDV更全面的测量，并且有助于确定与接触这些不同形式TDV的青少年的健康风险行为之间的关联。
