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 of pregnant Hispanic women.
BACKGROUND A growing body of evidence suggests that physical activity during pregnancy can reduce risk of pregnancy complications . However , factors influencing activity in pregnant Hispanic women , who have high rates of sedentary activity as compared to non-Hispanic whites , are not well characterized . PURPOSE To assess patterns and correlates of physical activity among 1355 participants in Proyecto Buena Salud , a prospect i ve cohort of pregnant Hispanic women in Massachusetts from 2006 to 2011 . METHODS Analyses were conducted in 2012 . Pre- , early- , mid- , and late-pregnancy physical activity were assessed using the Pregnancy Physical Activity Question naire . Women reported the frequency and duration of household/caregiving , occupational , sports/exercise , and transportation activities  and were classified according to compliance with American College of Obstetricians and Gynecologists guidelines for physical activity . RESULTS Household/caregiving activity was the primary mode of pregnancy activity ranging from 56 % to 60 % of total activity while sports/exercise contributed the least ( < 10 % ) . Compared to nulliparous women , women with two or more children were 85 % less likely to become inactive at any time during pregnancy ( OR=0.15 , 95 % CI=0.04 , 0.56 , p-trend < 0.01 ) . Women with one or more children increased their total physical activity on average 9.73±2.04 MET-hours/week and 12.04±2.39 MET-hours/week , respectively , with the onset of pregnancy ( p<0.01 ) . Those with the highest levels of total physical activity prior to pregnancy were 87 % less likely to become inactive with the onset of pregnancy than those who were inactive prior to pregnancy ( OR=0.13 , 95 % CI= 0.05 , 0.29 ) . CONCLUSIONS Findings can inform culturally appropriate interventions design ed to reduce pregnancy complications through the promotion of physical activity during pregnancy
