多导睡眠图（PSG）被认为是评估睡眠的“黄金标准”，但成本和负担限制了它的使用。尽管腕部活动记录仪和自我报告日记是PSG的可行替代方案，但很少有研究将这三种方式同时在家中多个晚上进行比较，以评估它们在多个睡眠结果中的相对有效性。这项研究比较了通过PSG、活动描记和睡眠日记测量的睡眠持续时间和连续性，并检查了种族/民族的适度性。来自全国妇女健康研究（SWAN）睡眠研究的参与者包括323名白人（n = 147）、非裔美国人（n = 120）和华裔（n = 56）中年社区妇女（平均年龄：51岁，范围：48-57岁）。连续三个晚上在参与者家中同时收集PSG、手腕活动记录仪（AW-64； Philips呼吸器，McMurray， PA）和睡眠日记。多变量重复测量线性模型比较了不同模式下的卧床时间（TIB）、总睡眠时间（TST）、睡眠效率（SE）、睡眠潜伏期（SL）和睡眠后醒来（WASO）。活动描记仪和PSG对睡眠持续时间和效率的估计相似。日记对TIB、TST和SE的估计高于PSG和活动描记术，而对SL和WASO的估计低于PSG。仅在白人女性中，日记性SL短于PSG SL，在非裔美国女性和白人女性中，日记性WASO低于PSG和活动性WASO。考虑到与PSG的一致性，活动描记法可能更适合作为PSG测量家庭睡眠的替代方法。未来的研究应该考虑种族/民族差异在日记中报告的睡眠连续性。
Polysomnography (PSG) is considered the “gold standard” for assessing sleep, but cost and burden limit its use. Although wrist actigraphy and self-report diaries are feasible alternatives to PSG, few studies have compared all three modalities concurrently across multiple nights in the home to assess their relative validity across multiple sleep outcomes. This study compared sleep duration and continuity measured by PSG, actigraphy, and sleep diaries and examined moderation by race/ethnicity. Participants from the Study of Women’s Health Across the Nation (SWAN) Sleep Study included 323 White (n = 147), African American (n = 120), and Chinese (n = 56) middle-aged community-dwelling women (mean age: 51 years, range: 48–57). PSG, wrist actigraphy (AW-64; Philips Respironics, McMurray, PA), and sleep diaries were collected concurrently in participants’ homes over three consecutive nights. Multivariable repeated-measures linear models compared time in bed (TIB), total sleep time (TST), sleep efficiency (SE), sleep latency (SL), and wake after sleep onset (WASO) across modalities. Actigraphy and PSG produced similar estimates of sleep duration and efficiency. Diaries yielded higher estimates of TIB, TST, and SE versus PSG and actigraphy, and lower estimates of SL and WASO versus PSG. Diary SL was shorter than PSG SL only among White women, and diary WASO was lower than PSG and actigraphy WASO among African American versus White women. Given concordance with PSG, actigraphy may be preferred as an alternative to PSG for measuring sleep in the home. Future research should consider racial/ethnic differences in diary-reported sleep continuity.
