Physical Activity Counselling Received Throughout Pregnancy and Effect on Behaviours: A Quasi-Experimental Study.

OBJECTIVES: The objective was to examine the frequency of physical activity (PA) counselling for pregnant women over the course of their pregnancies and the effect on the women's PA behaviour. METHODS: A quasi-experimental study was conducted in the maternity unit of a hospital. In total, 72 pregnant women were randomized into a control or intervention group. Counselling about PA was dispensed to the women in the intervention group throughout pregnancy by health professionals who had been sensitized to its importance and the recommendations. The women in the control group received the usual consultation content. The PA behaviour of pregnant women in the intervention group who reported receiving PA counselling was evaluated. The counselling and PA levels were evaluated by chi-square tests and repeated measures analysis of variance, respectively. RESULTS: Overall, the women received little counselling in accordance with the recommendations, although the intervention group women received this counselling more frequently (P = 0.049). All women in the intervention group who reported receiving counselling throughout pregnancy limited their decline in PA compared with those in the control group. The decline in total PA among normal-weight and overweight pregnant women was reduced in the intervention group (respectively, P = 0.043 and P = 0.044). CONCLUSION: Our intervention showed the effectiveness of counselling on PA behaviour, although the effect was observed at the end of pregnancy. Training and sensitizing for professionals should be strengthened to ensure that counselling in line with the recommendations to maintain or increase PA levels throughout pregnancy is provided.
