Increased time in sedentary behaviour was significantly associated with higher levels of C Reactive Protein and LDL Cholesterol , and a larger newborn abdominal circumference .
Discrepancies were found in associations of sedentary behaviour with gestational weight gain , hypertensive disorders , and birth weight .
No consistent associations were found between sedentary behaviour and other variables such as gestational diabetes .
Conclusions Our review highlights the significant time spent in sedentary behaviour during pregnancy , and that sedentary behaviour may impact on pregnancy outcomes for both mother and child .
Background In the general population , at least 50 % of time awake is spent in sedentary behaviours .
Sedentary behaviours are activities that expend less energy than 1.5 metabolic equivalents , such as sitting .
The amount of time spent in sedentary behaviours is a risk factor for diseases such as type 2 diabetes , cardiovascular disease , and death from all causes .
Even individuals meeting physical activity guidelines are at a higher risk of premature death and adverse metabolic outcomes if they sit for extended intervals .
The associations between sedentary behaviour with type 2 diabetes and with impaired glucose tolerance are stronger for women than for men .
It is not known whether sedentary behaviour in pregnancy influences pregnancy outcomes , but if those negative outcomes observed in general adult population also occur in pregnancy , this could have implication s for adverse outcomes for mothers and offspring .
We aim ed to determine the proportion of time spent in sedentary behaviours among pregnant women , and the association of sedentary behaviour with pregnancy outcomes in mothers and offspring .
Impact of an exercise intervention on physical activity during pregnancy: the behaviors affecting baby and you study.
OBJECTIVES We examined the impact of a prenatal exercise intervention on physical activity in 260 women at risk for gestational diabetes mellitus . METHODS We r and omized participants in the Behaviors Affecting Baby and You ( BABY ) Study , which took place from 2007 to 2012 , to either a 12-week individually tailored , motivationally matched exercise intervention ( n=132 ) or to a comparison health and wellness intervention ( n=128 ) . We assessed physical activity with the Pregnancy Physical Activity Question naire . We used linear mixed models to evaluate the impact of the interventions on change in physical activity according to intensity and type , total walking , and sedentary behavior . RESULTS Compared with the health and wellness arm , the exercise arm had significantly greater increases in sports or exercise activity ( 0.3 vs 5.3 metabolic equivalent of task [ MET ] hours/week ; P<.001 ) , and smaller declines in total activity ( -42.7 vs -2.1 MET hours/week ; P=.02 ) and activities of moderate to vigorous intensity ( -30.6 vs -10.6 MET hours/week ; P=.05 ) , and was more likely to achieve recommended guidelines for physical activity ( odds ratio=2.12 ; 95 % confidence interval=1.45 , 3.10 ) . CONCLUSIONS These findings extend the previous literature by demonstrating the benefits of a clinical ly feasible exercise intervention in an ethnically and socio-economically diverse population . Given the increased risk of adverse maternal health outcomes in ethnic minority groups , these findings may have important implication s for reducing health disparities
