(1) To analyze the effectiveness of a school-based sleep education program on sleep duration, latency, and efficiency, as well as separated by weekdays and weekend days and by sex. (2) To analyze children's sleep patterns (duration, latency, and efficiency) on weekdays and weekend days and by sex. A total of 110 children (average age of 8.4 (0.3) years, 62% girls) (experimental group (60 children, girls 52%) and control group (50 children, girls 74%) from 5 schools in Granada (Spain) participated in the study. The sleep patterns were measured by accelerometers attached to the non-dominant wrist 7 days/24 h, and by sleep log. The program lasted 8 weeks with a total of eight activities (one activity per week). Regarding our first objective, sleep duration decreased significantly in both groups on weekdays (p = 0.004) and weekend days (p < 0.001), and this reduction in sleep duration was lower in the experimental group than control group. By sex, girls of the experimental group reported a lower reduction in sleep duration on weekdays (p = 0.037) and weekend days (p < 0.001) than boys and reported better sleep efficiency than boys (p = 0.050). Regarding the second objective, children slept 12.41 min more on weekend days than weekdays (p = 0.037). Our sleep program did not increase the sleep duration in children, but it did increase sleep efficiency for girls on weekend days. Long-term multicomponent programmes that involve families to a greater extent seem necessary to improve this health-related behavior.

（1）分析以学校为基础的睡眠教育计划对睡眠时间，潜伏期和效率以及按工作日，周末和性别分开的有效性。（2）按性别分析儿童在工作日和周末的睡眠方式（持续时间，潜伏期和效率）。来自西班牙格拉纳达5所学校的110名儿童（平均年龄为8.4（0.3）岁，女童为62％）（实验组（60名儿童，女童52％）和对照组（50名儿童，女童74％）参加了实验在这项研究中，通过连接至非主要腕部的加速度计/ 24小时/ 7小时和睡眠记录来测量睡眠模式，该程序持续8周，共进行8次活动（每周一次活动）。客观而言，两组的工作时间在工作日均显着减少（p = 0.004）和周末（p  <0.001），并且实验组的睡眠时间减少量低于对照组。就性别而言，实验组的女孩报告说，他们在工作日（p  = 0.037）和周末（p  <0.001）的睡眠时间减少量低于男孩，并且报告的睡眠效率比男孩更好（p  = 0.050）。关于第二个目标，儿童在周末的睡眠时间比工作日多12.41分钟（p  = 0.037）。我们的睡眠计划并未增加儿童的睡眠时间，但确实增加了周末女孩的睡眠效率。为了改善这种与健康有关的行为，似乎有必要在更大程度上使家庭参与到长期的多方面计划中。
