Research evidence suggests that actigraphy is a very important instrument in documenting sleep/wake patterns of people with a variety of sleep disorders or motor dysfunctions. The present actigraphic investigation examined physical activity and sleep profiles as a function of gender in volunteers monitored in their natural environment. Irrespective of age, women exhibited better sleep quality than did men. This was demonstrated by higher sleep efficiency index and lower frequency of transitions between sleep and wakefulness. Additionally, women slept more than men and had shorter sleep onset latency. However, no significant gender effect on daytime activity level and circadian activity amplitude was observed.
研究证据表明，活动记录仪是记录各种睡眠障碍或运动功能障碍患者睡眠/觉醒模式的非常重要的工具。本次活动记录仪调查在自然环境中监测志愿者，研究身体活动和睡眠状况与性别的关系。不论年龄，女性的睡眠质量优于男性。这体现在更高的睡眠效率指数以及更低的睡眠与觉醒之间的转换频率上。此外，女性睡眠时间比男性长，入睡潜伏期更短。然而，未观察到性别对白天活动水平和昼夜活动幅度有显著影响。
