目的分析百岁老年人睡眠现状,为评价睡眠对老年人的影响提供依据。方法收集我国7个长寿之乡所有百岁老人自我报告的睡眠质量信息,对所纳入老年人进行睡眠时间和睡眠时间类别的分组比较。结果百岁老年人自述睡眠时间平均为(7.9±2.6)h,男性为(7.8±2.4)h,女性为(7.9±2.6)h,性别间睡眠时间差异无统计学意义(t=-0.4,P>0.05)。睡眠时间不足(<7 h)、过多(≥9 h)的比例分别为35.8%、36.0%,睡眠时间适中(≥7 h且<9 h)的比例(28.2%)最低。自述睡眠质量好、不好的比例分别为64.8%、35.2%;其睡眠时间分别为(8.6±2.3)、(6.5±2.5)h,睡眠时间差异有统计学意义(t=-8.3,P<0.01)。自报睡眠质量好与睡眠质量差的老年人中睡眠时间不足、适中、过多的比例分别为18.4%、35.6%、46.0%和67.7%、14.7%、17.6%,两组构成差异有统计学意义(χ2=9.3,P<0.05)。自感幸福和不幸福的两组百岁老人睡眠时间分别为(7.9±2.6)h和(7.4±2.5)h,睡眠时间的差异无统计学意义(t=1.3,P>0.05);但是两组老年人睡眠时间不足、适当、过多的比例分别为35.0%、28.3%、36.7%、44.4%,27.8%和27.8%,两组老年人睡眠时间构成差异无统计学意义(χ2=1.6,P>0.05)。结论睡眠时间与百岁老人的睡眠质量有明显的关系。
Objective To analyze the current situation of sleep in centenarians and provide basis for evaluating the effect of sleep on the elderly. Methods Self-reported sleep quality information was collected from all centenarians in 7 townships of longevity in our country, and the groups of sleeping and sleeping time categories were compared among the elders. Results The mean age of self-reported sleep in centenarians was (7.9 ± 2.6) h, (7.8 ± 2.4) h in men and (7.9 ± 2.6) h in females. There was no significant difference in sleeping time between the sexes (t = -0.4, P> 0.05). The proportion of patients who slept for less than 7 h and 35.8% and 36.0% respectively when their duration of sleep was less than 7 h and their sleep time was moderate were the lowest (28.2%). The sleep quality was good and bad (64.8%, 35.2% respectively). The sleep time was (8.6 ± 2.3) and (6.5 ± 2.5) h respectively, and the difference of sleep time was statistically significant (t = -8.3, P < 0.01). Self-reported good quality of sleep and poor quality of sleep in elderly poor, moderate, excessive proportions were 18.4%, 35.6%, 46.0% and 67.7%, 14.7%, 17.6%, two groups were statistically significant differences Significance (χ2 = 9.3, P <0.05). The sleeping time of the two groups of centenarians who felt self-feeling and unhappiness were (7.9 ± 2.6) h and (7.4 ± 2.5) h, respectively, and there was no significant difference in sleeping time (t = 1.3, P> 0.05) The sleep time of the elderly group was 35.0%, 28.3%, 36.7%, 44.4%, 27.8% and 27.8%, respectively. There was no significant difference in the sleep time between the two groups (χ2 = 1.6, P> 0.05). Conclusion Sleep time is significantly related to sleep quality of centenarians.
