Early school start times may curtail children's sleep and inadvertently promote sleep restriction. The current study examines the potential implications for early school start times for behavioral problems in public elementary schools (student ages 5-12 years) in Kentucky.
School start times were obtained from school Web sites or by calling school offices; behavioral and disciplinary problems, along with demographic information about schools, were obtained from the Kentucky Department of Education. Estimated associations controlled for teacher/student ratio, racial composition, school rank, enrollment, and Appalachian location.
Associations between early school start time and greater behavioral problems (harassment, in-school removals, suspensions, and expulsions) were observed, although some of these associations were found only for schools serving the non-Appalachian region.
Findings support the growing body of research showing that early school start times may contribute to student problems, and extend this research through a large-scale examination of elementary schools, behavioral outcomes, and potential moderators of risk.
较早的上学时间可能会减少儿童的睡眠时间，并在无意中导致睡眠受限。本研究考察了肯塔基州公立小学（学生年龄为 5-12 岁）较早的上学时间对行为问题的潜在影响。
从学校网站或致电学校办公室获取上学时间；从肯塔基州教育部获取有关学校的行为和纪律问题以及人口统计信息。估计关联控制了师生比、种族构成、学校排名、入学率和阿巴拉契亚地区的位置。
观察到上学时间较早与更多行为问题（骚扰、校内开除、停学和开除）之间存在关联，但这些关联仅在为非阿巴拉契亚地区服务的学校中发现。
研究结果支持越来越多的研究表明，较早的上学时间可能会导致学生出现问题，并通过对小学、行为结果以及风险的潜在调节因素的大规模检查来扩展这项研究。
