重要性移动智能手机正迅速成为与许多美国人沟通的有效手段。使用移动应用程序，他们可以访问远程数据库，跟踪时间和位置，并整合用户输入以提供量身定制的健康信息。目的：在一项随机临床试验中评估一款提供个性化、实时防晒建议的智能手机移动应用程序。设计、环境和参与者本试验于2012年进行，采用随机前测后对照设计，随访10周。数据收集自一个全国性的人口调查小组。来自知识小组的604名非西班牙裔和西班牙裔成年人，年龄在18岁或以上，拥有Android智能手机。这款手机应用程序根据预测的紫外线指数、手机的时间和位置以及用户输入，提供有关防晒（即保护措施和晒伤风险）和警报（涂抹或重新涂抹防晒霜并远离阳光）、每小时紫外线指数和维生素D生成的建议。收集过去3个月使用防晒措施的天数百分比、正午在户外晒太阳的时间（天数和分钟）以及晒伤次数。结果：与对照组相比，治疗组的个体报告了更多的遮荫使用（平均在阴凉处停留的天数，41.0%比33.7%,P = 0.03），但较少的防晒霜使用（平均天数，28.6%比34.5%,P = 0.048）。两组在过去3个月的晒伤次数无显著差异（治疗组平均0.60次vs对照组平均0.62次；P = 0.87）。那些使用手机应用程序的人报告说，他们在阳光下的时间更少（平均每天晒太阳的时间最少，应用程序用户为60.4%，而非用户为49.3%,P = 0.04），并且使用所有保护措施的时间更多（平均每天，39.4%对33.8%,P = 0.04）。结论和相关性该手机应用程序在一定程度上提高了防晒效果。手机应用程序的使用率低于预期，但与增加防晒有关。在人们晒太阳的时间和地点提供个性化的建议可能有助于减少阳光照射。
IMPORTANCE Mobile smartphones are rapidly emerging as an effective means of communicating with many Americans. Using mobile applications (apps), they can access remote databases, track time and location, and integrate user input to provide tailored health information.OBJECTIVE A smartphone mobile app providing personalized, real-time sun protection advice was evaluated in a randomized clinical trial.DESIGN, SETTING, AND PARTICIPANTS The trial was conducted in 2012 and had a randomized pretest-posttest controlled design with a 10-week follow-up. Data were collected from a nationwide population-based survey panel. A sample of 604 non-Hispanic and Hispanic adults from the Knowledge Panel 18 years or older who owned an Android smartphone were enrolled.INTERVENTIONS The mobile app provided advice on sun protection (ie, protection practices and risk of sunburn) and alerts (to apply or reapply sunscreen and get out of the sun), hourly UV Index, and vitamin D production based on the forecast UV Index, the phone's time and location, and user input.MAIN OUTCOMES AND MEASURES Percentage of days using sun protection and time spent outdoors (days and minutes) in the midday sun and number of sunburns in the past 3 months were collected.RESULTS Individuals in the treatment group reported more shade use (mean days staying in the shade, 41.0% vs 33.7%; P = .03) but less sunscreen use (mean days, 28.6% vs 34.5%; P = .048) than controls. There was no significant difference in number of sunburns in the past 3 months (mean, 0.60 in the treatment group vs 0.62 for controls; P = .87). Those who used the mobile app reported spending less time in the sun (mean days keeping time in the sun to a minimum, 60.4% for app users vs 49.3% for nonusers; P = .04) and using all protection behaviors combined more (mean days, 39.4% vs 33.8%; P = .04).CONCLUSIONS AND RELEVANCE The mobile app improved some sun protection. Use of the mobile app was lower than expected but associated with increased sun protection. Providing personalized advice when and where people are in the sun may help reduce sun exposure.
