The structure of the interrelations among a variety of health-enhancing behaviors was examined using structural equation modeling analyses of questionnaire data from 1,280 middle school students and 2,219 high school students. The health-enhancing behaviors included seat belt use, adequate hours of sleep, attention to healthy diet, adequate exercise, low sedentary behavior, and regular toothbrushing. In the middle school sample, all of the health-enhancing behaviors correlated significantly but modestly with each other, except for sleep with toothbrushing. In the high school sample, all but three of the 15 correlations among the behaviors were significant. The results further show that a single underlying factor can account for the modest correlations among these health-enhancing behaviors in both samples. The generality of the single-factor model was also established for male, female, White, Hispanic, and Black students at each school level. These findings provide some support for the existence of health-related lifestyles in adolescence.
利用对1280名中学生和2219名高中生的问卷调查数据进行结构方程模型分析，研究了各种促进健康行为之间的相互关系结构。促进健康的行为包括使用安全带、充足的睡眠时间、关注健康饮食、适度运动、低久坐行为和定期刷牙。在中学样本中，除了睡眠与刷牙外，所有促进健康的行为之间都存在显著但适度的相关性。在高中样本中，行为之间的15种相关性中有12种是显著的。结果进一步表明，一个单一的潜在因素可以解释这两个样本中这些促进健康行为之间的适度相关性。单因素模型在各学校水平的男、女、白人、西班牙裔和黑人学生中也得到了验证。这些发现为青少年中存在与健康相关的生活方式提供了一些支持。
