“…That being said, the ActiGraph GT9X Link watch has shown good accuracy, sensitivity, and specificity compared with polysomnography (the gold standard) in other populations. [31][32][33] It is also possible that actigraphy may overestimate sleep for inpatients as a result of lying in a hospital bed; this bias is minimized within the actigraph algorithm by accounting for light-dark and lack of motion. Although the true effect size that we found was 21% rather than 25% as proposed in our sample size calculations, the 25% effect size was chosen a priori for clinical significance and still achieved statistical significance; our absolute difference of more than 1 hour between groups is likely more clinically significant than a percent decrease.…”

OBJECTIVE: To evaluate whether antepartum hospitalization was associated with differences in sleep duration or disrupted sleep patterns. METHODS: This was a prospective cohort study with enrollment of pregnant people aged 18–55 years with singleton gestations at 16 weeks of gestation or more between 2021 and 2022. Each enrolled antepartum patient was matched by gestational age to outpatients recruited from obstetric clinics at the same institution. Participants responded to the ISI (Insomnia Severity Index) and wore actigraph accelerometer watches for up to 7 days. The primary outcome was total sleep duration per 24 hours. Secondary outcomes included sleep efficiency (time asleep/time in bed), ISI score, clinical insomnia (ISI score higher than 15), short sleep duration (less than 300 minutes/24 hours), wakefulness after sleep onset, number of awakenings, and sleep fragmentation index. Outcomes were evaluated with multivariable generalized estimating equations adjusted for body mass index (BMI), sleep aid use, and insurance type, accounting for gestational age correlations. An interaction term assessed the joint effects of time and inpatient status. RESULTS: Overall 58 participants were included: 18 inpatients and 40 outpatients. Inpatients had significantly lower total sleep duration than outpatients (mean 4.4 hours [SD 1.6 hours] inpatient vs 5.2 hours [SD 1.5 hours] outpatient, adjusted β=−1.1, 95% CI, −1.8 to −0.3, P=.01). Awakenings (10.1 inpatient vs 13.8, P=.01) and wakefulness after sleep onset (28.3 inpatient vs 35.5 outpatient, P=.03) were lower among inpatients. There were no differences in the other sleep outcomes, and no interaction was detected for time in the study and inpatient status. Inpatients were more likely to use sleep aids (39.9% vs 12.5%, P=.03). CONCLUSION: Hospitalized pregnant patients slept about 1 hour/day less than outpatients. Fewer awakenings and reduced wakefulness after sleep onset among inpatients may reflect increased use of sleep aids in hospitalized patients.
