Abstract
The overarching objective of the Pregnancy 24/7 cohort study (R01HL153095, NCT04749849) was to objectively measure 24-hour movement behavior among 500 participants for 7 days in each trimester of pregnancy and to examine associations of these behaviors with hypertensive disorders of pregnancy and other adverse pregnancy outcomes. Study aims and hypotheses included:
Aim 1: Examine associations of sedentary behavior patterns with hypertensive disorders of pregnancy. Hypothesis: Pregnant people with a consistently high sedentary behavior pattern across trimesters will have a higher incidence of gestational hypertension/preeclampsia, after adjustment for moderate-vigorous physical activity.
Aim 2: Examine associations of sleep patterns with hypertensive disorders of pregnancy. Hypotheses: Pregnant people with short sleep duration or poor sleep quality patterns across trimesters will have a higher incidence of gestational hypertension/preeclampsia, after adjustment for moderate-vigorous physical activity.
Aim 3: Estimate optimal 24-hour activity cycle patterns during pregnancy to reduce the risk of hypertensive disorders of pregnancy. Hypothesis: Statistically reallocating time in Sedentary behavior for light-physical activity or moderate-vigorous physical activity, but not sleep (among adequate duration sleepers), will be associated with a lower incidence of gestational hypertension/preeclampsia.
This shared dataset includes data generated to address these three aims and includes the following de-identified datasets: 24-hour movement behavior data (activPAL and Actiwatch), chart abstracted adverse pregnancy outcomes, and demographic characteristics.
