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 .
Adherence to physical activity guidelines in mid-pregnancy does not reduce sedentary time: an observational study
Background Physical activity ( PA ) interventions design ed to prevent prenatal complications have focused on increasing moderate PA yielding conflicting results . Minimal attention has focused on the evaluation of sleep , sedentary behavior ( SB ) , light activity or total daily PA during pregnancy . The purpose of this prospect i ve , longitudinal study was to 1 ) objective ly quantify and compare habitual PA and SB during the 2nd and 3rd trimester ; and 2 ) evaluate differences in activity patterns for women meeting prenatal PA guidelines versus those that did not . Methods Forty-six participants wore 2 PA monitors ( SenseWear ® Mini and activPAL ™ ) during week 18 and week 35 of pregnancy . We compared differences in sleep duration , postural allocation , daily steps , and PA between the 2nd and 3rd trimester and for women who met and did not meet PA guidelines . Results During the 2nd trimester , 30 % of the women ’s day ( 24-hours ) was total sleep ; 52 % SB ; 13 % light ; 3 % moderate ; and 0 % vigorous PA . Light ( P = 0.05 ) , vigorous ( P = 0.02 ) , and moderate-vigorous PA ( MET-minutes ; P = 0.02 ) , decreased with a trend in increased SB ( P = 0.07 ) . Activity of other intensities and sleep duration did not significantly change . Only 39 % and 37 % of participants slept between 7–9 hours/night at week 18 and 35 , respectively . Forty-six percent ( n = 21 ) and 28 % ( n = 13 ) of participants met prenatal PA guidelines during the 2nd and 3rd trimester , respectively . At week 18 , no differences in total sleep , SB , or light PA existed for women who met PA guidelines versus those who did not ; total PA was significantly greater for women who met guidelines . At week 35 , women that met PA guidelines had significantly less SB ( P < 0.005 ) than women who did not . Conclusions This study demonstrates that pregnant women spend the majority of their day in SB . Significant reductions in total activity across pregnancy may be attributed , in part to shifts in light PA and increased SB . Based on the lifestyle of our sample , regardless of meeting PA guidelines in mid-pregnancy , no significant difference exists in time spent in SB , however meeting PA recommendations in late pregnancy may reduce SB . Future interventions should target reducing SB by increasing light and moderate PA beyond volitional exercise
