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.

Résumé

Objectifs

Notre étude porte sur les effets des associations individuelles et combinées entre l’activité physique modérée à vigoureuse (APMV) et le temps de sédentarité (TS) (mesuré par accéléromètre), ainsi qu’entre l’APMV et le temps de télévision (TT) (autodéclaré) et les biomarqueurs cardiométaboliques durant la grossesse.

Méthode

Les participantes étaient 332 femmes enceintes ayant participé aux cycles 2003–2006 de la National Health and Nutrition Examination Survey (NHANES). Des modèles de régression linéaire multiple ont été appliqués aux liens individuels et combinés entre l’APMV, le TS et le TT élevés/faibles et les biomarqueurs cardiométaboliques suivants : indice de masse corporelle (IMC), pression systolique (PS), pression diastolique (PD), cholestérol à lipoprotéines de haute densité (HDL) et protéine C réactive (CRP).

Résultats

L’IMC était significativement plus faible chez les femmes dont l’APMV était élevée (≥ 17 min/j) que chez celles dont l’APMV était faible (< 17 min/j). La PS et la PD étaient significativement plus faibles chez les femmes dont le TS était faible (< 503 min/j) que chez celles dont le TS était élevé (≥ 503 min/j). L’IMC et la protéine CRP log-transformée étaient significativement plus faibles chez les femmes dont le TT était faible (< 3 h/j) que chez celles dont le TT était élevé (≥ 3 h/j). La PS et la PD étaient plus faibles (ptendance < 0,03) chez les femmes qui présentaient une combinaison de TS faible et d’APMV élevée. Et l’IMC et la protéine CRP log-transformée étaient plus faibles (ptendance < 0,00) chez les femmes qui présentaient une combinaison de TT faible et d’APMV élevée.

Conclusion

Il faut tenir compte à la fois de l’activité physique et du temps de sédentarité pour améliorer la santé cardiométabolique durant la grossesse.
