Exposure to the sun's UV radiation is a leading cause of skin cancer. Positive attitudes and beliefs about sun safety behavior, which would make sun protective behavior more likely, could be promoted and supported by school policies and practices.
To identify school characteristics associated with having adopted practices that promote sun safety.
DESIGN, SETTING, AND PARTICIPANTS: School-level data from the February 3 to July 23, 2014, School Health Policies and Practices Study's Healthy and Safe School Environment questionnaire were analyzed. The School Health Policies and Practices Study uses a 2-stage sampling design to select a nationally representative sample of schools. All public, state-administered, Catholic, and non-Catholic private schools with any of the grades from kindergarten through 12 were eligible for inclusion. All analyses were conducted using weighted data.
Prevalence of sun safety practices.
In a nationally representative sample of 828 US schools, representatives of 577 schools (69.7%) responded. Overall, sun safety practices were not common among schools. The most frequent practice was having teachers allow time for students to apply sunscreen at school (47.6%; 95% CI, 42.4%-52.9%). Few schools made sunscreen available for students to use (13.3%; 95% CI, 10.2%-17.0%), almost always or always scheduled outdoor activities to avoid times when the sun was at peak intensity (15.0%; 95% CI, 11.4%-19.6%), or asked parents to ensure that students applied sunscreen before school (16.4%; 95% CI, 12.9%-20.6%). High schools were less likely than elementary schools and middle schools to adopt several practices: for instance, 37.5% of high schools (95% CI, 29.7%-46.0%), 51.6% of middle schools (95% CI, 43.3%-59.7%), and 49.5% of elementary schools (95% CI, 42.0%-57.0%) had teachers allow time for students to apply sunscreen at school, and 11.8% of high schools (95% CI, 7.7%-17.5%), 18.2% of middle schools (95% CI, 13.3%-24.4%), and 14.7% of elementary schools (95% CI, 9.6%-21.8%) almost always or always scheduled outdoor activities to avoid times when the sun was at peak intensity. Other school characteristics were either not significantly associated with the adoption of any of the sun safety school practices studied (eg, metropolitan status) or were inconsistently associated with such policies and practices (eg, region, percentage of students eligible for free or reduced-price lunch, and school enrollment).
School practices that could protect children and adolescents from sun exposure and that could change norms about sun safety are not common. Interventions aimed at increasing the adoption of sun safety practices among schools are needed regardless of the level, location, size, and poverty concentration of the school. Such practices would cost little to implement and would support other messages targeted toward children, adolescents, adults, and parents, with an aim to reduce skin cancer morbidity and mortality.
暴露于太阳紫外线辐射是皮肤癌的主要病因。学校政策和实践可以促进并支持对阳光安全行为持积极态度和信念,这会使防晒行为更有可能发生。
确定与采用促进阳光安全实践相关的学校特征。
设计、设置和参与者:分析了2014年2月3日至7月23日学校健康政策与实践研究的健康与安全学校环境调查问卷中的学校层面数据。学校健康政策与实践研究采用两阶段抽样设计来选择具有全国代表性的学校样本。所有从幼儿园到12年级的公立、州立管理、天主教和非天主教私立学校均符合纳入条件。所有分析均使用加权数据进行。
阳光安全实践的普及率。
在828所美国学校的全国代表性样本中,577所学校(69.7%)的代表做出了回应。总体而言,阳光安全实践在学校中并不常见。最常见的做法是让教师留出时间让学生在学校涂抹防晒霜(47.6%;95%置信区间,42.4%-52.9%)。很少有学校为学生提供防晒霜以供使用(13.3%;95%置信区间,10.2%-17.0%),几乎总是或总是安排户外活动以避开太阳强度峰值时段(15.0%;95%置信区间,11.4%-19.6%),或者要求家长确保学生在上学前涂抹防晒霜(16.4%;95%置信区间,12.9%-20.6%)。高中比小学和初中采用多种做法的可能性更小:例如,37.5%的高中(95%置信区间,29.7%-46.0%)、51.6%的初中(95%置信区间,43.3%-59.7%)和49.5%的小学(95%置信区间,42.0%-57.0%)让教师留出时间让学生在学校涂抹防晒霜,11.8%的高中(95%置信区间,7.7%-17.5%)、18.2%的初中(95%置信区间,13.3%-24.4%)和14.7%的小学(95%置信区间,9.6%-21.8%)几乎总是或总是安排户外活动以避开太阳强度峰值时段。其他学校特征要么与所研究的任何阳光安全学校实践的采用没有显著关联(例如,大都市地位),要么与这些政策和实践的关联不一致(例如,地区、符合免费或减价午餐条件的学生百分比以及学校入学人数)。
能够保护儿童和青少年免受阳光照射并改变阳光安全规范的学校实践并不常见。无论学校的级别、位置、规模和贫困集中程度如何,都需要采取干预措施以增加学校采用阳光安全实践的情况。此类实践实施成本低廉,并将支持针对儿童、青少年、成年人和家长的其他信息传递,旨在降低皮肤癌的发病率和死亡率。
