Programme Bouge Grossesse : une application smartphone pour améliorer l'activité physique quotidienne chez les femmes enceintes

Abstract : During pregnancy physical activity decreases considerably and can cause increased gestational weight gain, greater birthweight and various obstetrical comorbidities. Physical activity has been shown to reduce obstetrical risks such as gestational hypertension, gestational diabetes mellitus, low back pain and cesarean delivery and has the benefit of increasing normal deliveries. Different strategies have been evaluated to improve physical activity during pregnancy but few have demonstrated significant results, including mobile health (mHealth) interventions. Objective : our aim was to evaluate the impact of a smartphone application which was developed to increase daily physical activity in pregnant women. Methods : we conducted a prospective randomized controlled study. We enrolled 250 pregnant women into an intervention group (n=125) where women were instructed to download the "Bouge Grossesse" application, and the same number of women into a control group (n=125) using a Placebo application. The intervention application consisted of a coaching program and a pedometer. The Placebo application consisted of a pedometer only. Primary outcome was defined as a daily increase of 2000 steps/day or 10 000 steps/week between week 1 (W1) and week 12 (W12). Secondary outcomes were the number of steps during the third trimester of pregnancy and the evolution of quality of life measured by WHO score (general well-being evaluation), EIFEL score (low back pain assessment) and Spiegel scale (assessment of sleep quality). Secondary outcome also concerned maternal and fetal outcomes (term of delivery and mode of delivery, birthweight, APGAR score, gestational diabetes mellitus, postpartum hemorrhage). Results : patients were enrolled between August 2017 and February 2019. We found a significant increase in the number of steps in the intervention group (65.9% success vs 19.4% in the placebo group, p<0.001). Concerning secondary outcomes, the EIFEL score was significantly lower in the success group (2.1 vs 5.7, p=0.046). There were no significant differences in the Spiegel and WHO scores. We found the mean number of daily steps during the third trimester was significantly higher in the intervention group (6837.9 vs 4126.2, p<0.001). We did not find any significant differences in maternal and fetal outcomes. Conclusion : the use of a mobile health intervention called "Bouge Grossesse" significantly increased physical activity in pregnant women in our study but these results need to be confirmed by future studies considering the high number of premature study terminations.
