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 .
The association of daily physical activity and birth outcome: a population-based cohort study
The potential relationship between daily physical activity and pregnancy outcome remains unclear because of the wide variation in study design s and physical activity assessment measures . We sought to prospect ively quantify the potential effects of the various domains of physical activity on selected birth outcomes in a large unselected population . The sample consisted of 11,759 singleton pregnancies from the Avon longitudinal study of parents and children , United Kingdom . Information on daily physical activity was collected by postal question naire for self-report measures . Main outcome measures were birth weight , gestational age at delivery , preterm birth and survival . After controlling for confounders , a sedentary lifestyle and paid work during the second trimester of pregnancy were found to be associated with a lower birth weight , while ‘ bending and stooping ’ and ‘ working night shifts ’ were associated with a higher birth weight . There was no association between physical exertion and duration of gestation or survival . Repetitive boring tasks during the first trimester was weakly associated with an increased risk of preterm birth ( < 37 weeks ) ( adjusted odds ratio [ OR ] = 1.25 , 95 % CI 1.04–1.50 ) . ‘ Bending and stooping ’ during the third trimester was associated with a reduced risk of preterm birth ( adjusted OR = 0.73 , 95 % CI 0.63–0.84 ) . Dem and ing physical activities do not have a harmful effect on the selected birth outcomes while a sedentary lifestyle is associated with a lower birth weight . In the absence of either medical or obstetric complications , pregnant women may safely continue their normal daily physical activities should they wish to do so
