The benefits of delaying school start times for secondary students are well-established. However, no previous study has considered how changing school start times impacts sleep and daytime functioning for K-12 teachers.
Teachers in a large suburban school district completed 3 annual surveys (pre-change n = 1687, post-change n = 1857, follow-up n = 1812) assessing sleep and daytime functioning.
With delayed start times, high school teachers had later rise times (high school [HS]: 28 minutes, middle school [MS]: 14 minutes), increased sleep duration (HS: 22 minutes, MS: 13 minutes), and improved daytime functioning. Improvements for middle school teachers were noted but were not statistically significant. With earlier start times, elementary teachers reported earlier bedtimes (9 minutes) and wake times (9 minutes), with no changes in sleep duration or daytime functioning.
IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: Today's school health policies often focus on wellness. Findings from this study reveal that the policy of healthy school start times can have a significant, positive impact on adults who teach in later-starting secondary schools. Later school start times for secondary teachers provide greater parity with their elementary colleagues in terms of sleep opportunity.
This study extends previous findings on how the policy of later secondary school start times improves the health and well-being of adolescents, highlighting that healthy start times contribute to increased sleep opportunity for MS and HS teachers and improved daytime functioning for HS teachers, with changed start times having no significant negative effect on elementary school teachers.
推迟中学生上学时间的益处已得到充分证实。然而，以往尚无研究探讨上学时间的改变对K-12教师的睡眠和日间功能有何影响。
一个大型郊区学区的教师完成了3次年度调查（改变前n = 1687，改变后n = 1857，随访n = 1812），评估睡眠和日间功能。
随着上学时间推迟，高中教师起床时间更晚（高中[HS]：28分钟，初中[MS]：14分钟），睡眠时间增加（HS：22分钟，MS：13分钟），日间功能改善。初中教师也有改善，但无统计学意义。随着上学时间提前，小学教师报告就寝时间（9分钟）和起床时间（9分钟）提前，睡眠时间和日间功能无变化。
对学校健康政策、实践和公平性的启示：当今的学校健康政策通常侧重于健康。本研究结果表明，健康的上学时间政策可对在上学时间较晚的中学任教的成年人产生重大积极影响。中学教师上学时间推迟使其在睡眠机会方面与小学同事更趋平等。
本研究扩展了以往关于中学上学时间推迟政策如何改善青少年健康和福祉的研究结果，强调健康的上学时间有助于增加初中和高中教师的睡眠机会，改善高中教师的日间功能，且上学时间的改变对小学教师无显著负面影响。
