Patterns of physical activity, sedentary behavior, and sleep across pregnancy before and during two COVID pandemic years.
Observational study in Midwifery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04749849 (Sedentary Behavior, Physical Activity, Sleep, and Cardiovascular Risk in Pregnancy), which is not on this map. Cited by 6 papers.
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.

Abstract
backgroundPhysical activity is recommended during pregnancy, and high sedentary behavior and poor sleep may increase the risk of pregnancy complications. Activity patterns and sleep were negatively impacted by the COVID pandemic in many segments of the population, but the impact of the pandemic on pregnant people is understudied. We aimed to compare patterns of physical activity, sedentary time, and sleep during pregnancy between a pre-COVID and a COVID-era cohort.
methodsPhysical activity, sedentary time, and sleep in each trimester of pregnancy were compared between two parallel prospective observational cohorts using identical collection methods. Pre-COVID participants (n=111) were recruited in 2017-2019 and COVID-era participants (n=117) from 2021-2023. Physical activity and sedentary time were measured using the activPAL3 micro accelerometer, and sleep duration was self-reported. Between-cohort comparisons were conducted using linear regression for each behavior in each trimester. Within-COVID-era cohort linear regression analyses assessed whether activity patterns differed as pandemic-era restrictions were eased.
resultsParticipant demographics were similar between cohorts except for self-reported income. Adjusted mean moderate-to-vigorous physical activity was 57-77 min/week higher in each trimester in pre-COVID compared to COVID-era participants (p<0.001); adjusted mean sedentary time was 0.77-1.13 hours/day lower in each trimester (p<0.01) and sleep duration was 0.8 hours/day lower in the third trimester in the pre-COVID compared to COVID-era cohort (p<0.05). Within the COVID-era cohort, no significant within-trimester differences were detected across the pandemic years.
conclusionsPregnant participants during the COVID pandemic were less active and more sedentary than their pre-pandemic counterparts, and this trend was still detected years after the pandemic began. A more sedentary lifestyle during pregnancy may have health implications, and prenatal care providers should help pregnant people identify strategies to adopt an active lifestyle in the context of pandemic-era barriers.
