Abstract
Background:Although physical activity during pregnancy may be beneficial, the prenatal period is a vulnerable time for decreasing physical activity levels and increasing sedentary time.Methods:This longitudinal cohort study measured physical activity using the Global Physical Activity Questionnaire (GPAQ) in singleton, pregnant women in the second (14–18 wk gestation; n = 332) and third trimester (29–33 wk; n = 256).Results:There was a significant decrease in total MVPA (MET mins/wk) between the second and third trimester (P = .01). The majority of physical activity time was spent in walking for transport (80%), and less than 2% in recreational activities. In both trimesters, being married was inversely associated with walking for transport (second trimester: β = –0.12 95% CI = –0.31 to –0.02, third trimester: β = –0.17 95% CI = –0.47 to –0.07) and owning a car was positively associated with recreational physical activity (second trimester: β = 0.16 95% CI = 0.02 to 0.32, third trimester: β = 0.17 95% CI = 0.04 to 0.27). The women spent an average of 5 hours per day sitting.Conclusions:The low and declining levels of physical activity during pregnancy in this population are a concern. Interventions that include lifestyle education and provision of accessible recreational physical activity programs for pregnant women are needed.
