“…Brisk walking was the most common type of physical activity at all time points, which is in line with findings in previous studies (Evenson et al, 2004;Mottola and Campbell, 2003;Ning et al, 2003). Increased focus has been put on the health benefits of walking in the adult population, and epidemiological studies suggest that they are substantial (Andersen, 2007).…”

“…However, the follow-up rate in gestational week 30 is high (92%) and the response rate in comparable studies varies between 41-74% (Hinton and Olson, 2001;Ning et al, 2003;Zhang and Savitz, 1996). When comparing demographic and reproductive variables between the MoBa participants and their births to the total number of births in Norway during the same period, there were only minor differences.…”

“…The prevalence of any physical activity during pregnancy varies widely and has been reported as high as 66% (Evenson et al, 2004;Ning et al, 2003). Understanding activity patterns during pregnancy and their correlates has significant public health implications.…”

The aims of this study were to describe the level of exercise during pregnancy and to assess factors associated with regular exercise. Using data from the Norwegian Mother and Child Cohort study (MoBa) conducted by the Norwegian Institute of Public Health, 34508 pregnancies were included in the present study. Data were collected by self-completed questionnaires in gestational week 17 and 30, and analyzed by logistic regression analysis.The results are presented as adjusted odds ratios (aOR) with 95% confidence interval (95% CI). The proportion of women exercising regularly was 46.4% before pregnancy and decreased to 28.0 and 20.4% in week 17 and 30, respectively. Walking and bicycling were the most frequently reported activities before and during pregnancy. The prevalence of swimming tended to increase from prepregnancy to week 30. Exercising regularly prepregnancy was highly related to regular exercise in week 17, aOR=18.4 (17

“…We also found that increasing income, being nulliparous and a worker was associated with a decreased time spent at home. Several others have reported the same factors as being associated with increased physical activity among pregnant women (Ning et al, 2003;Petersen et al, 2005;Schmidt et al, 2006) which suggests an inverse relationship between our measure of time spent at home and physical activity measures in other studies. These were all cross-sectional studies using various methods: self-reported activities based on an interview at time of birth, 24-h recall diaries during each trimester and a random sample of the population from a behavioral risk factors surveillance system.…”

Numerous studies suggest that in utero exposures to environmental contaminants are associated with fetal development, congenital anomalies, learning difficulties or other health impacts later in life. Although location and time-activity data have been used to model exposure to specific contaminants in epidemiological studies, little information is available about time-activity patterns of pregnant women. We measured changes in location-based activity patterns over the course of pregnancy (48-h periods, during two or three trimesters) using a self-reported time-activity log among a nonrandom sample of pregnant women (n ¼ 62). We assessed the influence of demographics and personal factors on changes in activity over pregnancy using mixed effects regression models. Increasing weeks of pregnancy was a significant predictor for increased time spent at home (1 h/day increase for each trimester of pregnancy), after adjusting for income (2.6 more h/day at home in lowest income group), work status (3.5 more h/day at home for nonworkers) and other children in the family (1.5 more h/day at home with other children). No other measured activities (time outdoors, time in transit modalities or time in other indoor locations) were related to weeks of pregnancy. As our results indicate that pregnant women tend to spend more time at home during the latter stages of pregnancy, future exposure and epidemiological research should consider the potential increase in home-based exposures (i.e., indoor air pollution or chemicals in the home) late in pregnancy, and increased confidence in exposure proxies based on home locations or characteristics during the same period.

“…circulatory, digestive, respiratory, secretory, genitourinary and the central nervous systems, is a condition for a healthy pregnancy [1]. As the pregnancy progresses, the relatively rapid weight gain, combined with endocrine changes and mood fluctuations, cause the woman to limit her daily physical activity [2,3]. This may sometimes lead to total akinesia [4], the consequences of which have been proven to have a more negative effect in pregnant than in non-pregnant women [5].…”

AB ST R ACT O B J E C T I V E S :The aim of the work was to assess the level of physical activity of women before and during pregnancy and to determine whether physical exercise influences the course and duration of labor and the postpartum period. M A T E R I A L A N D M E T H O D S :The study encompassed 63 pregnant women aged 19-36, with a mean pregnancy weight gain of 7-27 kg, no contraindication to physical activity, and term birth. Physical activity was assessed at three stages: before and during pregnancy, and during the postpartum period, with the use of the seven-day international IPAQ questionnaire. The respondents' physical condition in the postpartum period was assessed with an original 26-item questionnaire. R E S U L T S : The self-assessed level of physical activity before pregnancy was moderate in most respondents (60.3%); only 12.7% of the respondents declared a low level of physical activity. During pregnancy the level of physical activity decreased in 25.4% of the respondents and significantly reduced in 11%. Women who were inactive before pregnancy remained inactive during pregnancy. The mean duration of the second stage of labor in women with moderate and high levels of physical activity was 43.61 min. The length of the entire postpartum period was the shortest (four weeks) in active women. C O N C L U S I O N S : Physical activity before and during pregnancy has an impact on the duration of labor and the postpartum period.
