The Second National Sun Survey (NSS2) was carried out in 2006 to estimate ultraviolet radiation (UVR) exposure, sun protection and related knowledge, attitudes and beliefs among Canadians. This paper provides a detailed overview of NSS2 methods and discusses the strengths and limitations of the survey. The NSS2 consists of two questionnaires administered to two samples of adults (age 16+ years). The base sample provides in-depth information on UVR exposure, protective behaviours, tanning, and knowledge, attitudes and beliefs about sun safety for adults, as well as some sun behaviour information for a sample of their children aged 1-12 years. The shorter comparison sample facilitates direct comparison with the 1996 first national sun survey. Data were collected using computer-assisted telephone interviewing, and sample weights were computed for all respondents for estimation and analysis of both adult and child data. Base sample interviews were completed for 7,121 adults, of whom 1,437 reported on the sun behaviour of one of their children, and the comparison sample yielded 2,115 interviews. Response rates were 63% for both surveys. The NSS2 provides in-depth and up-to-date UVR exposure information among Canadians. The results of this survey will aid health promotion experts and policy-makers in developing effective programs to minimize UVR exposure. A public use data file and training in statistical analysis of the NSS2 has been made available to data analysts from across Canada. Key strengths and limitations identified in this survey will inform the development and implementation of future sun surveys.
第二次国家阳光调查（NSS2）于 2006 年进行，旨在估计加拿大人口的紫外线辐射（UVR）暴露、防晒措施以及相关知识、态度和信念。本文详细介绍了 NSS2 的方法，并讨论了该调查的优势和局限性。NSS2 由两个针对成年人群体（16 岁及以上）的问卷组成。基础样本提供了 UVR 暴露、保护行为、晒黑以及关于防晒安全的知识、态度和信念的深入信息，还为 1 至 12 岁儿童的样本提供了一些阳光行为信息。简短的比较样本有助于与 1996 年的第一次全国阳光调查进行直接比较。使用计算机辅助电话访谈收集数据，并为所有受访者计算样本权重，以便对成人和儿童数据进行估计和分析。基础样本共完成了 7121 名成年人的访谈，其中 1437 人报告了其一名子女的阳光行为，比较样本产生了 2115 次访谈。两次调查的回应率均为 63%。NSS2 提供了加拿大人口深入和最新的 UVR 暴露信息。该调查结果将帮助健康促进专家和政策制定者制定有效的计划，以尽量减少 UVR 暴露。已向加拿大各地的数据分析师提供了 NSS2 的公共使用数据文件和统计分析培训。本调查中确定的主要优势和局限性将为未来阳光调查的制定和实施提供信息。
