The objectives were to: (1) describe sleep timing and patterns among adolescents who live or work on farms; (2) compare these sleep characteristics to those of nonfarm adolescents; (3) explore whether the above sleep and farm versus nonfarm differences varied by age and gender.
Participants were aged 11-16 years and were abstracted from the 2014 Canadian Health Behaviour in School-aged Children study. Records from 2,160 farm adolescents were frequency matched (by school, gender, and grade) to records from 2,210 nonfarm adolescents. Participants self-reported their bedtimes and wake-up times on weekdays and weekends.
Among farm adolescents, average nightly sleep duration (hours:minutes) ranged from 08:34 among 14- to 16-year-old girls to 09:21 among 11- to 13-year-old girls. Approximately 24% to 32% of farm adolescents did not meet minimal sleep duration targets. For 11- to 13-year-olds, sleep characteristics did not differ according to farm status. However, for 14- to 16-year-olds, farm adolescents had shorter sleep durations than nonfarm adolescents (23 minutes for boys, P = .02; 20 minutes for girls, P = .06). Furthermore, a greater proportion of 14- to 16-year-old farm boys had sleep duration values less than the recommended 8 hours/night (27.7% vs 19.6%, P = .05).
This study profiles the sleep experiences of 11- to 16-year-old farm adolescents. Almost 1 in 3 of these adolescents did not get adequate sleep. Older adolescents who lived or worked on a farm slept less than comparably aged nonfarm adolescents. This may reflect their participation in morning chores essential to the farm operation and may increase their injury risk.
本研究旨在：（1）描述居住或工作在农场的青少年的睡眠时间和模式；（2）将这些睡眠特征与非农场青少年进行比较；（3）探讨上述睡眠差异和农场与非农场差异是否因年龄和性别而异。
参与者年龄在 11-16 岁之间，他们来自 2014 年加拿大青少年健康行为研究。从 2160 名农场青少年的记录中按照学校、性别和年级进行频数匹配，得到 2210 名非农场青少年的记录。参与者报告他们在工作日和周末的就寝时间和起床时间。
在农场青少年中，平均夜间睡眠时间（小时：分钟）从 14-16 岁女孩的 08:34 到 11-13 岁女孩的 09:21 不等。约 24%至 32%的农场青少年没有达到最小睡眠时间目标。对于 11-13 岁的青少年，睡眠特征与农场状态无关。然而，对于 14-16 岁的青少年，农场青少年的睡眠时间比非农场青少年短（男孩为 23 分钟，P=0.02；女孩为 20 分钟，P=0.06）。此外，更多 14-16 岁的农场男孩的睡眠时间值小于推荐的 8 小时/夜（27.7%比 19.6%，P=0.05）。
本研究描述了 11-16 岁农场青少年的睡眠体验。近 1/3 的青少年睡眠不足。居住或工作在农场的青少年睡眠较少，这可能反映了他们参与农场运营所必需的早晨家务劳动，并且可能增加他们受伤的风险。
