Recent changes in communication technologies, including increased reliance on mobile phones and the internet, may present challenges and/or opportunities to re-engaging inactive study cohorts. We evaluate our ability to recruit participants for the Kidskin Young Adult Myopia Study (KYAMS), a follow-up of the Kidskin Study.
KYAMS participants were recruited from the Kidskin Study, a sun exposure-intervention study for 5-6 year-olds running from 1995 to 1999 with most recent follow-up in 2005. From 2015 to 2019, the KYAMS used mail-outs, phone calls and social media to contact Kidskin Study participants. Multivariable logistic regression was used to identify variables associated with successful contact of a Kidskin Study participant or family member and KYAMS participation.
Of 1695 eligible participants, 599 (35.5%) participants (or a family member) were contacted and 303 (17.9%) participated in the KYAMS. KYAMS participation was more likely in those who participated in the 2005 follow-up (odds ratio [OR] = 5.09, 95% confidence interval [CI]: 3.67-7.06) and had a mobile phone number on record (OR = 2.25, CI: 1.57-3.23). Of those contacted, participants who were the first point of contact (OR = 4.84, CI: 2.89-8.10) and who were contacted by letter in the first (OR = 6.53, CI: 3.35-12.75) or second (OR = 5.77, CI: 2.85-11.67) round were more likely to participate in the KYAMS, compared to contact by landline phone.
We recruited approximately one-fifth of Kidskin Study participants for the KYAMS. Participants were more likely to participate in the KYAMS if they were contacted directly, rather than through a family member, and if they were contacted by invitation letter.

通讯技术的最新变化，包括对手机和互联网的日益依赖，可能给重新接触不活跃的研究对象群体带来挑战和/或机遇。我们评估了我们为 Kidskin 青少年近视研究（KYAMS）招募参与者的能力，这是一项针对 5-6 岁儿童的阳光暴露干预研究的后续研究，该研究从 1995 年持续到 1999 年，最近一次随访是在 2005 年。从 2015 年到 2019 年，KYAMS 通过邮寄、电话和社交媒体联系 Kidskin 研究的参与者。多变量逻辑回归用于确定与成功联系 Kidskin 研究参与者或家庭成员以及 KYAMS 参与相关的变量。
KYAMS 的参与者是从 Kidskin 研究中招募的，这是一项针对 5-6 岁儿童的阳光暴露干预研究，从 1995 年持续到 1999 年，最近一次随访是在 2005 年。从 2015 年到 2019 年，KYAMS 通过邮寄、电话和社交媒体联系 Kidskin 研究的参与者。多变量逻辑回归用于确定与成功联系 Kidskin 研究参与者或家庭成员以及 KYAMS 参与相关的变量。
在 1695 名合格参与者中，有 599 名（35.5%）参与者（或其家庭成员）被联系，其中 303 名（17.9%）参与者参加了 KYAMS。那些参加了 2005 年随访的人（优势比[OR] = 5.09，95%置信区间[CI]：3.67-7.06）和有手机号码记录的人（OR = 2.25，CI：1.57-3.23）更有可能参加 KYAMS。在被联系的参与者中，作为第一联系点的参与者（OR = 4.84，CI：2.89-8.10）和首先通过信件联系的参与者（OR = 6.53，CI：3.35-12.75）或第二轮（OR = 5.77，CI：2.85-11.67）更有可能参加 KYAMS，而不是通过座机电话联系。
我们招募了 Kidskin 研究参与者的大约五分之一参加 KYAMS。如果参与者直接联系，而不是通过家庭成员联系，如果他们通过邀请函联系，他们更有可能参加 KYAMS。
