Short Sleep Is Associated With Low Bone Mineral Density and Osteoporosis in the Women's Health Initiative

Abstract: Short sleep duration, recognized as a public health epidemic, is associated with adverse health conditions, yet little is known about the association between sleep and bone health. We tested the associations of usual sleep behavior and bone mineral density (BMD) and osteoporosis. In a sample of 11,084 postmenopausal women from the Women's Health Initiative (WHI; mean age 63.3 years, SD = 7.4), we performed a cross-sectional study of the association of self-reported usual hours of sleep and sleep quality (WHI I… Show more

“…However, other authors emphasize that both short and long sleep time in middle aged persons and elderly people is associated with signi cantly increased risk of osteoporosis, and an appropriate sleep time may help in delaying or preventing osteoporosis [33,34]. However, discussions on the appropriate length of sleep in people with osteoporosis are still ongoing.…”

“…We have not shown a statistically signi cant relationship between sleep length and QUALEFFO 41. The literature (2020) describes that short sleep time (less or equal to 5 h) was associated with lower BMD and higher risk of osteoporosis [32]. Ochs-Balcom HM et al in a group of 11 084 postmenopausal women observed that short sleep time (less than or equal to 5 h) was associated with lower BMD and higher risk of osteoporosis.…”

“…Lower melatonin levels due to reduced light exposure may lead to fewer interactions between estrogen and its receptors and, thus, negatively impact BMD [ 79 ]. However, other studies report either positive or null relationships between sleep duration and BMD in postmenopausal women [ 80 , 81 , 82 , 83 ]. The conflicting evidence in this area may be due to confounding study participant factors that are not uniformly controlled for across the studies, such as age, body composition, diet, and nighttime-only sleep duration versus inclusion of daytime naps.…”
