“…The study participants were of low-risk pregnancy, retention of the sample was high and the final sample included those without any medical complications. Comparisons of the study sample with published data demonstrated that they were broadly representative of British women in terms of habitual activity, socioeconomic status and birth outcomes (Clarke et al, 2005).…”

Significant changes in physical activity among pregnant women in the UK as assessed by accelerometry and self-reported activity

2005

Objective: Research on the impact of maternal physical activity on pregnancy outcomes has often employed subjective measures of physical activity obtained by diary or questionnaire. This study investigates the feasibility of using accelerometry as an objective measure of physical activity of pregnant women compared with subjective data obtained via activity recall among pregnant women. Design: Activity data were collected prospectively on 57 women at 12, 16, 25, 34 and 38 weeks of gestation. Total daily physical activity was assessed by ambulatory accelerometer and activity interview (self-report). Maternal personality variables (health value, extroversion) were assessed by established scales. Setting: Leicestershire, UK. Subjects: Pregnant women were recruited by voluntary participation via antenatal booking clinics. In all, 64 pregnant women with low-risk pregnancy were enrolled onto the study, of whom 57 completed the study. Results: Mean 24 h physical activity levels (PAL) decreased significantly from second to third trimester as assessed by self-report interview (1.51-1.29 Metabolic Equivalent TEE-h/day, Po0.01) and accelerometry (200.05-147.42 counts/min, Po0.01). The correlation between the two measures declined as pregnancy progressed (r value ranging from 0.55 to 0.08). Compliance with the accelerometers declined from 90% at 12 weeks to 47% at 34 weeks (Po0.01). Compliance with the self-report interviews was 100%. Those who fully complied with the accelerometry demonstrated a significantly higher health value (Po0.05) and a significantly greater level of extroversion (Po0.05) than those who did not. Conclusions: Accelerometers and self-reported activity interviews both indicated a significant decline in PAL during pregnancy. Although subjects showed a willingness to use both methods, accelerometers resulted in variable compliance with 72 h monitoring. Both techniques may be limited by the need to measure low levels of physical activity during the third trimester. Sponsorship: Cambridge Neurotechnology Ltd, UK, assisted with the provision of Actiwatch accelerometers.

“…Continuous monitoring of day and night-time activity was included to examine change in sleep patterns during pregnancy (Clarke et al, 2005). Women were instructed to go about their normal daily routine and only remove the actiwatch during periods of bathing or watersports.…”

“…The pregnancy PA patterns have so far been investigated through questionnaires (Lof and Forsum, 2006) or interviews (Clarke et al, 2005;Rousham et al, 2006;Borodulin et al, 2008). However, the reliability and validity of all selfreported methods is limited because of misreporting or miscoding of activities, inaccurate estimation of activity intensity or duration and differences in body mass.…”

“…The energy cost of DIT seems to be unaltered (Nagy and King, 1984;Poppitt et al, 1993;Spaaij et al, 1994;Bronstein et al, 1995;Piers et al, 1995;Prentice et al, 1996) or even reduced (Contaldo et al, 1987;Illingworth et al, 1987;KoppHoolihan et al, 1999). The energy cost attributed to PA is generally low (Lawrence and Whitehead, 1988;Butte et al, 2004;Clarke et al, 2005;Lof and Forsum, 2006;Rousham et al, 2006) and tends to decrease as pregnancy advances (Lawrence et al, 1985;van Raaij et al, 1987;Singh et al, 1989;Heini et al, 1991;Forsum et al, 1992).…”

Pregnancy-related changes in activity energy expenditure and resting metabolic rate in Switzerland

et al. 2009

Background/Objectives: To measure resting metabolic rate (RMR), activity energy expenditure (AEE), total energy expenditure (TEE) and physical activity pattern, that is, duration and intensity (in metabolic equivalents, METs) of activities performed in late pregnancy compared with postpartum in healthy, well-nourished women living in Switzerland. Subjects/Methods: Weight, height, RMR, AEE, TEE and physical activity patterns were measured longitudinally in 27 healthy women aged 23-40 years at 38.2 ± 1.5 weeks of gestation and 40.0 ± 7.2 weeks postpartum. Results: The RMR during late pregnancy was 7480 kJ per day, that is, 1320±760 kJ per day (21.4%) higher than the postpartum RMR (Po0.001). Absolute changes in RMR were positively correlated with the corresponding changes in body weight (r ¼ 0.61, Po0.001). RMR per kg body weight was similar in late pregnancy vs postpartum (P ¼ 0.28). AEE per kg during pregnancy and postpartum was 40 ± 13 and 50 ± 20 kJ/kg, respectively (P ¼ 0.001). There were significant differences in daily time spent at METso1.5 (1067 vs 998 min, P ¼ 0.045), at 2.5pMETs o3.0 (58 vs 82 min, P ¼ 0.002) and METsX6 (1 vs 6 min, P ¼ 0.014) during pregnancy and postpartum, respectively. Conclusions: Energy expenditure in healthy women living in Switzerland increases in pregnancy compared with the postpartum state. Additional energy expenditure is primarily attributed to an increase in RMR, which is partly compensated by a decrease in AEE. The decrease in physical activity-related energy costs is achieved by selecting less demanding activities and should be taken into account when defining extra energy requirements for late pregnancy in Switzerland.

“…Studies of physical activity patterns during pregnancy show a low prevalence of recommended activity levels 15,16,17 , as well as a decline of leisure physical activity/sports/exercise and occupational activity across gestation 6,15,16,18,19,20,21,22,23,24 . Even so, there is some evidence that household and childcare activities are maintained over the course of pregnancy 18,22 or increase in the third trimester 23 .…”
