To examine the impact of sun exposure on human health, accurate measures of past sun exposure are required. We investigated how young adults' recall of childhood sun-related behaviours compares with parent-reported measures collected during childhood. The Kidskin-Young Adult Myopia Study (KYAMS) is a follow-up of the Kidskin Study, a sun-protection intervention study conducted from 1995-2001. KYAMS participants, aged 25-30 years, reported time in sun, and use of hats and sunscreen, for each year from ages 5-26 years (n = 244). Using weighted kappa, we assessed agreement between these data and corresponding variables derived from the Kidskin Study parent questionnaires completed when KYAMS participants were aged 6-12 years. Ordinal logistic regression was used to test the association between self-reported sun-behaviours and corresponding parent-reported data. We found slight agreement between self-reported and parent-reported data for all sun-behaviour measures except hat use at 12 years. KYAMS recall of time in sun at 8-12 years was not associated with Kidskin Study parent-reported responses after adjustment for current time in sun. Recall of higher hat and sunscreen use was associated with higher parent-reported hat and sunscreen use (OR[hat] = 1.37, 95% CI: 1.16, 1.62; OR[sunscreen] = 1.23, 95% CI: 1.03, 1.48). However, KYAMS self-reported data were unable to predict corresponding parent-reported responses. Group data from retrospective recall of sun-related behaviours may be of limited value in studying the relationship between sun exposure and health outcomes; however, individual data are likely of little use.
为了研究阳光暴露对人类健康的影响，需要准确测量过去的阳光暴露情况。我们调查了年轻人对儿童时期阳光相关行为的回忆与儿童时期父母报告的测量结果之间的比较。Kidskin-Young Adult Myopia Study (KYAMS) 是一项对 Kidskin Study 的随访研究，该研究是一项从 1995 年至 2001 年进行的防晒干预研究。KYAMS 参与者年龄在 25-30 岁之间，报告了他们从 5 岁到 26 岁时每年在阳光下的时间，以及使用帽子和防晒霜的情况（n=244）。使用加权 Kappa，我们评估了这些数据与 KYAMS 参与者年龄在 6-12 岁时完成的 Kidskin Study 父母问卷中相应变量之间的一致性。有序逻辑回归用于检验自我报告的阳光行为与相应的父母报告数据之间的关联。我们发现，除了 12 岁时戴帽子的行为外，自我报告和父母报告的数据在所有阳光行为测量方面都存在轻微的一致性。在调整当前阳光暴露后，KYAMS 对 8-12 岁时阳光暴露时间的回忆与 Kidskin Study 父母报告的反应没有关联。回忆更高的帽子和防晒霜使用与更高的父母报告的帽子和防晒霜使用相关（帽子：OR[hat]=1.37，95%CI：1.16，1.62；防晒霜：OR[sunscreen]=1.23，95%CI：1.03，1.48）。然而，KYAMS 的自我报告数据无法预测相应的父母报告反应。从回顾性回忆阳光相关行为中获得的组数据可能在研究阳光暴露与健康结果之间的关系方面价值有限；然而，个人数据可能用处不大。
