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 .
Physical activity, sedentary behavior and risk of hypertensive disorders of pregnancy in Hispanic women
Objective : Prior studies of the association between physical activity and  hypertensive disorders of pregnancy have been conflicting ; the majority focused on leisure-time activity only , did not use physical activity question naires vali date d for pregnancy , and were conducted in primarily non-Hispanic white population s. Methods : We prospect ively evaluated this association among 1240 Hispanic women in Proyecto Buena Salud . The Pregnancy Physical Activity Question naire , vali date d for use in pregnancy , was used to assess pre- and early pregnancy sports/exercise , household/caregiving , occupational and transportation activity . Diagnoses of hypertensive disorders of pregnancy were based on medical record abstract ion and confirmed by the study obstetrician . Results : A total of 49 women ( 4.0 % ) were diagnosed with a hypertensive disorder of pregnancy , including 32 women ( 2.6 % ) with pre-eclampsia . In age-adjusted analyses , high levels of early pregnancy household/caregiving activity were associated with reduced risk of total hypertensive disorders ( OR = 0.4 , 95 % CI 0.1–0.9 ) and pre-eclampsia ( OR = 0.3 , 95 % CI 0.1–0.9 ) relative to low levels ; however , these findings were no longer statistically significant in multivariable models . Pre-pregnancy activity and pattern of activity from pre- to early-pregnancy were not significantly associated with risk . Finally , sedentary behavior was not significantly associated with hypertensive disorders . Conclusion : Findings from this prospect i ve study of Hispanic women were consistent with those of prior prospect i ve cohorts indicating that physical activity prior to and during early pregnancy does not significantly reduce risk of hypertensive disorders of pregnancy
