- Abstract
Objectives: This study examined the impacts of individual and combined associations between moderate-to-vigorous physical activity (MVPA) and sedentary time (ST) (accelerometer-derived), as well as MVPA and television (TV) time (self-reported) on cardiometabolic biomarkers during pregnancy. Methods: Participants were 332 pregnant women from the 2003–2006 cycles of the National Health and Nutrition Examination Survey (NHANES). Multiple linear regression models were conducted to examine the relationships between individual and combinations of high/low MVPA, ST, and TV time with cardiometabolic biomarkers: body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), high-density lipoprotein cholesterol (HDL), and C-reactive protein (CRP). Results: Women with high MVPA (≥ 17 min/day) compared to those with low MVPA (< 17 min/day) had significantly lower BMI. Women with low ST (< 503 min/day) compared to those with high ST (≥ 503 min/day) had significantly lower SBP and DBP. Women with low TV (< 3 h/day) compared to those with high TV (≥ 3 h/day) had significantly lower BMI and log-transformed CRP. Women with a combination of low ST/high MVPA had lower SBP and DBP (ptrend < 0.03). Women with a combination of low TV/high MVPA had lower BMI and log-transformed CRP (ptrend < 0.00). Conclusion: We need to consider both physical activity and sedentary time for improved cardiometabolic health during pregnancy.
