简介：只有少数协议的研究之间的主观措施的睡眠和actigraphy.OBJECTIVE：比较自我报告的睡眠和actigraphy在这个年龄组，通过研究性别差异，并使用一种新的图形方法，生存协议plot.METHODS：37名受试者，年龄在12至17岁，回答有关夜间睡眠时间和使用actigraphy为7天的问题。使用知情睡眠和记录睡眠之间的平均值和中位数差异、组内相关系数、Bland-Altman图和生存一致性图。（标准差= 2.1;中位数= 0.5; p <0.01），男孩高于男孩，（标准差= 2.8;中位数= 1.6; p <0.05），女孩为0.5小时（标准差= 1.4;中位数= 0.3; p = 0.11）。图形评价显示了相似的结果，以及组内相关系数：男孩为0.06（95%CI =-0.33-0.46; p = 0.489），女孩为0.43（95%CI = 0.12 - 0.83; p <0.001）。这些结果是相关的，因为据我们所知，这是巴西青少年睡眠和活动记录主观测量之间一致性的第一项研究。此外，他们强调需要谨慎使用夜间睡眠措施的青少年，主要是男孩。
INTRODUCTION: There are only few agreement studies between subjective measures of sleep and actigraphy among adolescents.OBJECTIVE: To compare self-reported sleep and actigraphy in this age group, by studying gender differences and, using a new graphical approach, the survival agreement plot.METHODS: Thirty-seven subjects, aged 12 to 17 years, answered questions about nocturnal sleep duration and used actigraphy for seven days. The mean and median differences between the informed sleep and the recorded one, the intraclass correlation coefficient, the Bland-Altman plot and the survival-agreement plot were used.RESULTS: A mean difference of about one hour (SD = 2.1; median = 0.5; p < 0.01) was found between both strategies, which was higher among boys, 1.9 hours (SD = 2.8; median = 1.6; p < 0.05), than among girls, 0.5 hours (SD = 1.4; median = 0.3; p = 0.11). The graphical evaluation showed similar results, as well as the intraclass correlation coefficient: 0.06 (95%CI = -0.33 - 0.46; p = 0.489) for boys and 0.43 (95%CI = 0.12 - 0.83; p < 0.001) for girls.CONCLUSIONS: Our data are consistent with previous studies as to non-agreement between the two methods. These results are relevant because this is the first study of concordance between subjective measures of sleep and actigraphy among Brazilian adolescents, as far as we know. In addition, they reinforce the need of a careful use of nocturnal sleep measures among adolescents, mainly among boys.
