Tanning equipment use is related to the early onset of cancer, with the risk increasing as the duration and repetition of exposure increase. In 2009, the International Agency for Research on Cancer classified tanning equipment use as carcinogenic to humans, and according to the World Health Organization, the risk of skin melanoma increases significantly when use begins before age 35.
The rapid response component of the 2014 Canadian Community Health Survey collected data on the use of tanning equipment in the previous 12 months, including reasons for use, frequency/duration of use, precautions taken, and adverse reactions or injuries. This analysis examines the prevalence of self-reported indoor tanning in a nationally representative sample of Canadians aged 12 or older in the 10 provinces.
In 2014, 4.5% of Canadians (an estimated 1.35 million) reported that they had used tanning equipment in the past year; 70.3% of them were female, and just over half of female users were aged 18 to 34. The prevalence of indoor tanning was highest among people with some postsecondary education and among those in higher income households (trend p-value ⟨ 0.0001). Most users reported fewer than 10 sessions in the past year. The most common reason (62.0%) was to develop a "protective" base tan.
Females made up the majority of tanning equipment users, particularly at ages 18 to 34. Efforts to increase awareness of the risks may be beneficial, given the high percentage of users who believed that indoor tanning offers some level of skin protection from future sun exposure.
使用晒黑设备与癌症的早期发病有关,暴露时间和频率的增加会增加风险。2009 年,国际癌症研究机构将晒黑设备的使用归类为对人类致癌物质,根据世界卫生组织的说法,当使用年龄在 35 岁之前开始时,皮肤黑色素瘤的风险会显著增加。
2014 年加拿大社区健康调查的快速反应部分收集了过去 12 个月内使用晒黑设备的数据,包括使用原因、使用频率/持续时间、采取的预防措施以及不良反应或伤害。本分析检查了在全国代表性的 10 个省份中年龄在 12 岁及以上的加拿大人群中自我报告的室内晒黑的流行率。
2014 年,4.5%的加拿大人(估计有 135 万人)报告称在过去一年中使用过晒黑设备;其中 70.3%为女性,略超过一半的女性使用者年龄在 18 至 34 岁之间。室内晒黑的流行率在接受过一些高等教育的人群和高收入家庭中最高(趋势 p 值 ⟨0.0001)。大多数使用者报告过去一年中进行了少于 10 次晒黑。最常见的原因(62.0%)是为了晒出“保护”的基础肤色。
女性占晒黑设备使用者的大多数,尤其是在 18 至 34 岁之间。考虑到大多数使用者认为室内晒黑在某种程度上提供了对未来阳光照射的皮肤保护,因此提高对风险的认识可能会有所帮助。
