“…Our findings are in agreement with some previous observational findings but not with others [5, 21, 27–29, 44, 45], and in disagreement with a randomized controlled trial by Barakat et al [46]. Barakat et al study included 142 women of low to middle socioeconomic position, and it may be expected that women who agree to randomization of their lifestyle during pregnancy constitute a selected group.…”

“…Barakat et al study included 142 women of low to middle socioeconomic position, and it may be expected that women who agree to randomization of their lifestyle during pregnancy constitute a selected group. Further, some of the observational studies included both elective and emergency C-section [27, 45, 47]; in the present study elective C-sections were excluded. This reduces comparability with part of the existing literature.…”

Objectives. To examine the association between maternal leisure time physical activity and mode of delivery. Study Design. Population-based multicentre cohort. From the Danish Dystocia Study, we included 2,435 nulliparous women, who delivered a singleton infant in cephalic presentation at term after spontaneous onset of labor in 2004-2005. We analysed mode of delivery according to self-reported physical activity at four stages, that is, the year before pregnancy and during first, second, and third trimester, in logistic regression models. Further, we combined physical activity measures at all four stages in one variable for a proportional odds model for cumulative logits. Main Outcome Measures. Mode of delivery (emergency caesarean section; vacuum extractor; spontaneous vaginal delivery). Results. The odds of emergency caesarean section decreased with increasing levels of physical activity with statistically significant trends at all four time stages except the third trimester. This tendency was confirmed in the proportional odds model showing 28% higher odds of a more complicated mode of delivery among women with a low activity level compared to moderately active women. Conclusions. We found increasing leisure time physical activity before and during pregnancy associated with a less complicated delivery among low-risk, nulliparous women.

“…The differences in women’s attitude about exercise between miscarriage groups may be due to elevated levels of anxiety in early pregnancy related to the fear of having another miscarriage and the common misconception that perinatal exercise behavior can lead to miscarriage (Clarke and Gross, 2004; Evenson et al, 2009; Hanghøj, 2013). However, there is limited evidence to support this claim; the majority of studies examining miscarriage and perinatal exercise have found that the risk is no higher for active pregnant women than for inactive pregnant women (Clapp, 1989; Maconochie et al, 2007; Magann et al, 2002; Schlüssel et al, 2008). Given the elevated depressive/anxiety symptoms among women with a history of miscarriage, promoting exercise as a way to improve perinatal mental health may help to improve the exercise attitudes of pregnant women (Da Costa et al, 2003).…”

Influences of prior miscarriage and weight status on perinatal psychological well-being, exercise motivation and behavior

2016

Objectives women who have experienced miscarriage may be at increased risk for elevated depressive and anxiety symptoms in subsequent pregnancies. Exercise may be a useful strategy for coping with these symptoms. Little is known about how miscarriage influences prenatal exercise behavior. The study purpose was to examine the influences of miscarriage history and prepregnancy weight status on pregnant women’s psychological health, exercise motivation, and behavior using the Theory of Planned Behavior. Participants/Setting Pregnant women (N=203; 41 with prior miscarriage; 72 overweight/obese; BMI > 25.0) in the northeast United States. Design Women prospectively reported their depressive/anxiety symptoms and exercise motivation/behavior in the 1st, 2nd, and 3rd trimesters via mailed surveys. Group differences in depressive/anxiety symptoms, exercise behavior, and its motivational determinants were examined using Chi Square analyses and Univariate and Multivariate Analyses of Covariance. Measurements and findings Women with a history of miscarriage had higher 1st and 2nd trimester depressive/anxiety symptoms and lower 1st trimester attitudes about exercise and 1st and 2nd trimester perceived behavior control than women without a history of miscarriage. Overweight/obese women had higher 1st and 2nd trimester pregnancy depressive/anxiety symptoms, engaged in less prepregnancy exercise, and had lower levels of exercise intention, attitude, and perceived behavior control throughout pregnancy than normal weight women. Key Conclusions Women with a history of miscarriage and overweight/obese women have poorer psychological health and lower motivation to exercise during pregnancy than women without a history of miscarriage and normal weight women. Implications for practitioners Interventions and healthcare provider communications aimed at promoting perinatal exercise behavior and psychological health should take into account pre-pregnancy weight status and pregnancy history to identify strategies to help women, particularly overweight/obese women with a history of miscarriage, to overcome exercise barriers.

“…Narendren 18 and Magann 16,17 each separated urgent/emergent from planned/elective cesareans, but these are still heterogeneous groups; a pregnant woman might have a cesarean birth for any one of a large number of indications (e.g., umbilical cord prolapse, twins, previous cesarean, fetal distress, etc.). If PA does affect cesarean risk, it is unlikely that all such pathways are involved.…”

“…9 Twenty-four previous studies have examined the association between PA or exercise during pregnancy and risk or odds of cesarean. 10–33 Reported effect estimates are not consistent across studies, with the slightly more than half reporting a decreased risk 19–32 of cesarean with higher levels of PA or exercise, but with a sizeable minority reporting no effect 10,12–14 , an increased risk 15–17,19 , decreased risk in one subgroup only 11 , or decreased risk of elective/planned cesareans but increased risk of urgent/emergent surgeries. 18 …”

Background Previous studies report conflicting results regarding a possible association between maternal physical activity (PA) and cesarean delivery. Methods 7-day PA recalls were collected by telephone from n=1205 pregnant women from North Carolina, without prior cesarean, during two time windows: 17-22 weeks and 27-30 weeks completed gestation. PA was treated as a continuous, non-linear variable in binomial regressions (log-link function); models controlled for primiparity, maternal contraindications to exercise, pre-eclampsia, pregravid BMI, and percent poverty. We examined both total PA and moderate-to-vigorous PA (MVPA) at each time. Outcomes data came from medical records. Results The dose-response curves between PA or MVPA and cesarean risk at 17-22 weeks followed an inverse J-shape, but at 27-30 weeks the curves reversed and were J-shaped. However, only (total) PA at 27-30 weeks was strongly associated with cesarean risk; this association was attenuated when women reporting large volumes of PA (>97.5th percentile) were excluded. Conclusion We did not find evidence of an association between physical activity and cesarean birth. We did, however, find evidence that associations between PA and risk of cesarean may be non-linear and dependent on gestational age at time of exposure, limiting the accuracy of analyses that collapse maternal PA into categories.

Antepartum, intrapartum, and neonatal significance of exercise on healthy low-risk pregnant working women

Abstract: Exercise in working women is associated with smaller babies, increased number of inductions and augmentations of labor, and longer labors. Colds and flu are more frequent in exercising women.
