Sun-induced skin damage, which increases skin cancer risk, is initiated in early life and promoted through later sun exposure patterns. If sun safety determinants are well understood and addressed during the school years, skin cancer incidence might be reduced. This study tested psychosocial influences on youth's sun safety and assessed their strength within and across gender and ethnicity in a sample of 1782 middle school students.
Predictors included sunburn and skin cancer knowledge, tanning attitudes, peer norms, and barriers regarding sun exposure and were assessed with a self-administered, validated questionnaire. The hypothesized relationships were tested with structural equation models and confirmed with multilevel regression.
Across gender and ethnicity, knowledge emerged as an important sun safety predictor with both direct and indirect effects mediated through tanning attitudes. The relationship with barriers did not reach statistical significance within any of the subgroups, possibly due to measurement limitations. An indirect effect of peer norms on sun safety, mediated through tanning attitudes, was confirmed only among girls. Also, an indication that peer norms operate differently within the ethnic groups was found, since this predictor had a statistically significantly stronger relationship with sun safety among non-Hispanics.
Youth's sun safety is a multifactorial practice, partially determined by ethnicity- and gender-based standards. In order to ensure health-promoting school environments, needed are multicomponent programs where peer norms and knowledge are salient and where sun safety is addressed individually and together with other health risk behaviors.
阳光导致的皮肤损伤会增加患皮肤癌的风险,这种损伤在早年就已开始,并通过后期的日晒模式进一步加剧。如果在学生时代就能很好地理解并解决防晒的决定因素,那么皮肤癌的发病率可能会降低。本研究测试了心理社会因素对青少年防晒的影响,并在1782名中学生样本中评估了这些因素在性别和种族内部及之间的影响力。
预测因素包括晒伤和皮肤癌知识、晒黑态度、同伴规范以及日晒的障碍,并通过一份经过验证的自填式问卷进行评估。通过结构方程模型对假设的关系进行测试,并通过多层回归进行确认。
在所有性别和种族中,知识都是一个重要的防晒预测因素,其直接和间接影响均通过晒黑态度介导。与障碍的关系在任何亚组中均未达到统计学显著性,这可能是由于测量限制所致。同伴规范通过晒黑态度对防晒产生的间接影响仅在女孩中得到证实。此外,研究发现同伴规范在不同种族群体中的作用方式不同,因为在非西班牙裔中,这一预测因素与防晒的关系在统计学上显著更强。
青少年的防晒是一个多因素的行为,部分由基于种族和性别的标准决定。为了确保促进健康的学校环境,需要实施多组分项目,其中同伴规范和知识很突出,并且要单独以及与其他健康风险行为一起解决防晒问题。
