Among adolescents, risk behaviors often cluster together and lead to risk behaviour syndromes. Multiple risk behaviors in turn become important determinants of health outcomes, including injuries.
A national sample (n = 11,415) of Canadian youth aged 11-15 years was examined from the 1997-1998 Health Behaviour in School-Aged Children Survey. Principal components analyses were used to characterize how adolescent risk behaviors cluster together into factors. Associations between these behavioral factors and injury outcomes were explored via multiple logistic regression analyses.
Two factors of risk behaviors emerged: lifestyle risks and psychological risks. Strong associations between the lifestyle risk scale and the occurrence of head and neck injuries were identified (P < 0.001 for trend). The relative odds for the highest quintile versus the lowest quintile were 6.96 (95% CI: 3.95-12.26). Similar injury risks were not identified in association with the psychological risk scale.
The findings provide novel information about potential causes of injury to young people and provide a reliable method by which researchers can quantify two determinants of health. These are helpful for injury control research in that they provided a means by which health risk behaviors can be measured and then related to the injury experiences of young people.
在青少年中，危险行为往往聚集在一起并导致危险行为综合征。多种危险行为反过来又成为健康结果（包括受伤）的重要决定因素。
从1997 - 1998年学龄儿童健康行为调查中选取了11415名11 - 15岁的加拿大青少年作为全国样本。采用主成分分析来描述青少年危险行为如何聚集成不同因素。通过多重逻辑回归分析探讨这些行为因素与受伤结果之间的关联。
出现了两个危险行为因素：生活方式风险和心理风险。确定了生活方式风险量表与头颈部受伤发生率之间存在强关联（趋势检验P < 0.001）。最高五分位数与最低五分位数相比的相对比值为6.96（95%可信区间：3.95 - 12.26）。未发现与心理风险量表相关的类似受伤风险。
这些发现为年轻人受伤的潜在原因提供了新信息，并为研究人员提供了一种可靠的方法来量化两个健康决定因素。这对伤害控制研究有帮助，因为它们提供了一种测量健康风险行为并将其与年轻人受伤经历相关联的方法。
