Abstract
Growing evidence illustrates the importance of 24-hour (h) activity, including moderate/vigorous-intensity physical activity (MVPA), light-intensity physical activity (LPA), sedentary behavior (SED), and sleep, for cardiovascular health. However, little is known about 24-hour activity during early pregnancy and if this varies by geographical location.
PURPOSE: To present first trimester data from a pregnancy cohort study and to examine differences in self-reported and device-based 24 h activity by site.
METHODS: This analysis includes all baseline data from the Pregnancy 24/7 Study, conducted at the Universities of Iowa, Pittsburgh, and West Virginia. At baseline (100-126 weeks gestation), participants completed surveys including self-reported physical activity and SED (Pregnancy Physical Activity Questionnaire) and sleep (Pittsburgh Sleep Quality Index). Participants wore activity and sleep monitors (activPAL3 and Actiwatch Spectrum Plus) concurrently for 7 days and completed a non-wear/sleep log. Descriptive statistics were used to describe self-reported and device-based 24 h activity. Differences across sites were examined using one-way ANOVA, Wilcoxon/Kruskal-Wallis, or chi-square tests.
RESULTS: A total of N = 500 women (mean age 30.6 ± 4.6 years, 17.4% minoritized group, 23% rural) enrolled and received the two monitors; n = 1 did not complete surveys. Differences in self-reported 24 h activity were observed across study sites, with West Virginia showing the highest levels of MVPA, LPA, household/caregiving, and occupational activities, while having the least optimal sleep parameters. Device-based MVPA was highest at Iowa and lowest at West Virginia.
CONCLUSIONS: Variations in 24 h activity were noted across sites, with discrepancies between self-reported and device-based assessments. Utilizing multiple assessment methods is necessary to gain a more complete understanding of 24 h activity during early pregnancy.
