To evaluate the effects of an appearance-focused intervention to reduce the risk of skin cancer by decreasing indoor tanning, examine potential heterogeneity in tanning across this time, and correlate the subtypes with predictors collected at baseline.
Randomized controlled trial with 379 female college students measured at 6 monthly time points.
Self-reported indoor tanning frequency.
The intervention was effective at decreasing tanning over the period between the fall and spring. Longitudinal latent class analysis found 3 patterns of tanners among the treatment individuals: abstainers, moderate tanners, and heavy tanners. These classes appeared in both the treatment and control conditions, and the intervention had a harm reduction effect by reducing levels of exposure within the moderate and heavy tanner classes. Participant age and self-reported tanning patterns were found to be predictive of class membership.
This research suggests that brief intervention approaches can be effective at reducing risk for skin cancer and illustrates several ways in which these protective effects can be enhanced.
评估一项以外观为重点的干预措施通过减少室内晒黑来降低皮肤癌风险的效果，研究这段时间内晒黑的潜在异质性，并将这些亚型与基线时收集的预测因素相关联。
对379名女大学生进行随机对照试验，每6个月测量一次。
自我报告的室内晒黑频率。
该干预措施在秋季至春季期间有效减少了晒黑。纵向潜在类别分析在治疗个体中发现了3种晒黑模式：戒晒者、中度晒黑者和重度晒黑者。这些类别在治疗组和对照组中均出现，并且该干预措施通过降低中度和重度晒黑者的暴露水平产生了减少危害的效果。研究发现参与者年龄和自我报告的晒黑模式可预测类别归属。
本研究表明，简短干预方法可有效降低皮肤癌风险，并说明了几种增强这些保护作用的方法。
