Feasibility and acceptability of longitudinal measurement of 24-hour movement profiles across pregnancy using research-grade devices paired with sleep diaries.
Article in Journal of activity, sedentary and sleep behaviors, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundComprehensive assessment of 24-hour movement profiles can reveal patterns of physical activity, sedentary behavior, and sleep across pregnancy. To fully capture sleep health, assessments should combine subjective measures (e.g. sleep diaries) with objective wearable data. However, collecting such data throughout pregnancy can be burdensome. This study evaluated the feasibility and acceptability of using a research-grade accelerometer and daily sleep diaries longitudinally.
methodsTen pregnant individuals were recruited at 10 weeks' gestation and followed until 35 weeks. Participants wore the ActiGraph CentrePoint Insight accelerometer continuously and completed daily sleep diaries one week per month. Feasibility was based on adherence (≥ 4 valid accelerometer wear days ≥ 10 h/day and ≥ 4 completed diaries per week). Acceptability was evaluated via participant-reported ease of use and comfort with the accelerometer and sleep diaries in a feedback questionnaire at 35 weeks.
resultsNine participants provided ≥ 4 valid accelerometer days per week for a mean of 15 weeks (range: 10-23; median: 15). Ten participants completed ≥ 4 days of text-based sleep diaries during assigned diary weeks for a mean of 5 months (range: 3-6, median: 6). Most (78%) found the sleep diaries easy to respond to and the watch comfortable, though several described the band as bulky. One-third (n = 3) experienced device issues, partially resolved through troubleshooting or replacement.
conclusionsLongitudinal 24-hour movement assessment using research-grade accelerometers paired with daily sleep diaries was feasible and acceptable for 90% of participants, though technical issues reduced wear time. Future studies should address comfort, anticipate device problems, and use reminders and text-based diaries to improve adherence.
