Sammendrag
A low level of daily PA and regular recreational exercise was shown in the present study of
pregnant women in Oslo. There was a decline in exercise intensity, duration and frequency from
before pregnancy and throughout the course of pregnancy. Walking was the most common
exercise mode. The results of the multivariate analysis showed that women who decreased regular
exercise in the 3rd trimester had higher weight gain and reported to have no social role models
with respect to exercise behaviour during childhood. Pre-pregnancy physical inactivity was the
strongest predictor of decreased maternal exercise in the 3rd trimester. There was no difference
between exercisers and non-exercisers with respect to pre-pregnancy body mass index (BMI) and
commonly reported pregnancy complaints such as pelvic girdle pain (PGP) and urinary
incontinence. Comparison of the PAPQ and the ActiReg indicated only small differences between
the two methods in cross-tabulation of total PA level and proportion of participants meeting the
current exercise guidelines. The Bland-Altman plot of the activity patterns showed a mean
difference near zero with no apparent trends and with a wide scatter of individual observations.
Drop-out rates of the present RCT were 19.2% and 20.8% in the EG and CG, respectively. Only
women attending regularly to the prescribed exercise program significantly reduced maternal
weight gain. No women attending 24 exercise sessions exceeded the IOM recommendations.
Weight retention 6-8 weeks postpartum was also significantly lower in women attending 24 exercise classes.
