The purpose of this study was to identify and characterize trajectory classes of adolescents who ride with an impaired driver (RWI) and drive while impaired (DWI).
We analyzed all 7 annual assessments (Waves W1-W7) of the NEXT Generation Health Study, a nationally representative longitudinal study starting with 10th grade (2009-2010 school year). Using all 7 waves, latent class analysis was used to identify trajectory classes with dichotomized RWI (last 12 months) and DWI (last 30 days; once or more = 1 vs. none = 0). Covariates were race/ethnicity, sex, parent education, urbanicity, and family affluence.
Four RWI trajectories and 4 DWI trajectories were identified: abstainer, escalator, decliner, and persister. For RWI and DWI trajectories respectively, 45.0% ( = 647) and 76.2% ( = 1,657) were abstainers, 15.6% ( = 226) and 14.2% ( = 337) were escalators, 25.0% ( = 352) and 5.4% ( = 99) were decliners, and 14.4% ( = 197) and 3.8% ( = 83) persisters. Race/ethnicity (χ = 23.93, = .004) was significantly associated with the RWI trajectory classes. Race/ethnicity (χ = 20.55, = .02), sex (χ = 13.89, = .003), parent highest education (χ = 12.49, = .05), urbanicity (χ = 9.66, = .02), and family affluence (χ = 12.88, = .05) were significantly associated with DWI trajectory classes.
Among adolescents transitioning into emerging adulthood, race/ethnicity is a common factor associated with RWI and DWI longitudinal trajectories. Our results suggest that adolescent RWI and DWI are complex behaviors warranting further detailed investigation of the respective trajectory classes. Our study findings can inform the tailoring of prevention and intervention efforts aimed at preventing illness/injury and preserving future opportunities for adolescents to thrive in emerging adulthood.
本研究的目的是识别和描述与受损驾驶员同乘（RWI）以及在受损状态下驾驶（DWI）的青少年的轨迹类别。
我们分析了下一代健康研究的所有7次年度评估（从W1到W7波次），这是一项具有全国代表性的纵向研究，始于10年级（2009 - 2010学年）。利用全部7个波次，采用潜在类别分析来识别具有二分法RWI（过去12个月）和DWI（过去30天；一次或多次 = 1，无 = 0）的轨迹类别。协变量包括种族/民族、性别、父母教育程度、城市化程度和家庭富裕程度。
识别出4种RWI轨迹和4种DWI轨迹：戒酒者、上升者、下降者和持续者。对于RWI和DWI轨迹，分别有45.0%（n = 647）和76.2%（n = 1,657）是戒酒者，15.6%（n = 226）和14.2%（n = 337）是上升者，25.0%（n = 352）和5.4%（n = 99）是下降者，14.4%（n = 197）和3.8%（n = 83）是持续者。种族/民族（χ = 23.93，p = .004）与RWI轨迹类别显著相关。种族/民族（χ = 20.55，p = .02）、性别（χ = 13.89，p = .003）、父母最高教育程度（χ = 12.49，p = .05）、城市化程度（χ = 9.66，p = .02）和家庭富裕程度（χ = 12.88，p = .05）与DWI轨迹类别显著相关。
在向成年早期过渡的青少年中，种族/民族是与RWI和DWI纵向轨迹相关的一个共同因素。我们的结果表明，青少年RWI和DWI是复杂行为，需要对各自的轨迹类别进行进一步详细研究。我们的研究结果可为旨在预防疾病/伤害以及为青少年在成年早期茁壮成长保留未来机会的预防和干预措施的定制提供参考。
