Brief summary

Our main objective is to evaluate the intervention that best enables women's adherence to physical activity (PA). Our hypothesis is that identifying types of interventions suitable for pregnant women (in-person PA sessions, videoconferences or mixed format) could help improve their PA level and simultaneously reduce their sedentary behavior (SB).

Detailed description

PA has beneficial effects on physical, psychological, and social health, and its regular practice helps to prevent numerous chronic diseases. During pregnancy, PA also has many benefits for women's physical condition, weight gain, gestational hypertension, lower back and pelvic pain, and postpartum depressive symptoms and may also reduce fetal macrosomia and positively affect neurogenesis, language development, memory, and other learning-associated cognitive functions. (CNSF 2021). PA is thus recommended to all pregnant women for 150 to 180 minutes a week, adapted to their health status, physical condition, and course of pregnancy. It is also recommended that women limit their Sedentary Behaviour (SB) (to ≤7 waking h/day) during pregnancy. No French study has assessed the impact of a PA program during pregnancy, and no published study has proposed videoconference PA sessions during pregnancy. Pregnant women's adherence to PA is a limiting factor found in many interventional studies. Possible changes in maternal behavior in practicing PA and reducing SB during pregnancy could also favorably affect the health of mother and child and thus subsequent PA. Given PA's many benefits and SB's harmful effects during pregnancy, assessing programs that enable pregnant women to both increase PA levels and reduce SB seems pertinent and valuable.

Interventions

BEHAVIORALIn person PA sessions

Group B women will have access to a weekly program of 3 face-to-face PA sessions. The face-to-face sessions will be offered at one or more locations in the Clermont-Ferrand area, depending on the number of groups taking part. They will also be offered at one or more times depending on the number of groups. Locations and times will be specified on the online booking software. Women can only register for 3 sessions per week.

BEHAVIORALInteractive videoconference PA sessions

Women in Group C will have access to a weekly program of 3 PA sessions via interactive videoconferencing. These sessions will have the same format as the face-to-face sessions with visualization of the APA professional, visualization of the participants (who can also choose to be masked). The PA professional will also see the participants, so he or she can correct positions and give individualized advice at any time. Schedules will be specified on the online booking software with the videoconference link. Women can only register for 3 sessions per week.

BEHAVIORALIn person and by videoconference (mixed format) PA sessions.

Women in Group D will have access to a weekly program of 3 mixed-format PA sessions, with 2 interactive distance learning sessions and 1 in-person session. The in-person sessions will be offered at one or more locations in the Clermont-Ferrand area, depending on the number of groups taking part. Locations and times will be specified on the online booking software. Women can only register for 1 face-to-face session per week. The other 2 sessions will be offered via interactive videoconferencing. These sessions will have the same format as the in-person sessions, with visualization of the APA professional, visualization of the participants. The APA professional will also see the participants, so he or she can correct positions and give individualized advice at any time. Schedules will be specified on the online booking software with the videoconference link. Women can only register for 2 videoconference's sessions per week.
