The project focuses on prevention of major pregnancy and birth related complications : pregnancy-induced hypertension (PIH), gestational diabetes mellitus (GDM), caesarean section (CS), and large-for-gestational-age (LGA), i.e. the birth weight of the baby exceeds the 90% percentile of birth weights for the specific pregnancy duration.
The investigators focus on the pre-conception period, i.e. the pre-conception period of the 2nd pregnancy in women with an excessive weight gain during their 1st pregnancy, aiming to decrease the complications rate in their 2nd pregnancy.
Women with an excessive gestational weight gain have obtained the extra weight during a rather short period of time, e.g. 20 kilos in the last 4 or 5 months of their pregnancy. This characteristic distinguishes the target group from the general population with overweight/obesity, in whom the extra weight was acquired during many years and independent from a pregnancy, making a behaviour change more complex.
The coaching intervention combines face-to-face counselling with the use of a mobile App connected to medical devices (scale and pedometer). The app monitors important indicators (weight, eating behaviour, physical activity, mental wellbeing), provides coaching through established behavioral change techniques, and is specifically tailored for women with excessive weight gain during the previous pregnancy.
The goal is to decrease the rate of pregnancy and birth-related adverse outcomes in the next pregnancy by a healthy life style, starting shortly after their 1st delivery and sustained during the next pregnancy.
The aim is to decrease the prevalence of pregnancy and birth-related complications (pregnancy-induced hypertension (PIH), gestational diabetes mellitus (GDM), caesarean section (CS), and large-for-gestational-age babies (LGA)). These complications occur in 26% of pregnancies with normal start BMI and adequate weight gain, in 34% in normal start BMI but excessive gestational weight gain and in up to 66% in obese class III (BMI≥40kg/m²) combined with excessive gestational weight gain. Moreover, as the prevalence of maternal obesity continues to rise, increasing numbers of children are exposed to an 'obesogenic intrauterine environment'. Obesity in pregnancy has therefore the potential to result in an 'intergenerational cycle' of obesity through in utero programming.
The investigators focus on women with excessive weight gain during their 1st pregnancy as currently, half of them do not return to their pre-pregnancy weight before the next pregnancy. This results in a complication rate as high as 42% (PIH, GDM, CS, LGA). The investigators target a healthy BMI at start of pregnancy by intervening during the pre-conception period- and an adequate weight gain during pregnancy by intervening during pregnancy in these women. The intervention will be evaluated in a randomized controlled trial including 1,100 women.
The proposed intervention combines face-to-face coaching with the use of a mobile App (so-called 'inter-act' app) connected to medical devices (scale and pedometer). The app monitors women's weight, eating behaviour, physical activity, mental wellbeing, and provides continuously coaching through positive behavioral change techniques. The 'inter-act' App covers after the 1st delivery breast-feeding support, while during pregnancy, the gestational weight gain guidelines of the Institute of Medicine (IOM) are included.
Drop out of less motivated women is avoided as the time points of the four pre-conception coaching sessions coincide with the existing postnatal follow-up visits for neonates (Governmental vaccination scheme through the organisation " Kind & Gezin"), and the three pregnancy coaching sessions coincide with the three routine ultrasound scans during normal pregnancy (KCE Guidelines).
Each year, there are 8,900 singleton pregnancies in Flanders in whom the mother had excessive gestational weight gain in the prior pregnancy. The current rate of at least one of the four major pregnancy and birth-related complications (PIH, GDM, CS, LGA) in the 8,900 pregnancies is 42%. If the complications rate reduces with 1/4, this involves more than 900 pregnancies, and reduces costs related to caesarean sections, gestational diabetes, obesity in mother & child.

| INTER-ACT | Behavioral | Pre-conception coaching sessions: We encourage less motivated women to participate to the trial by collaborating with Kind & Gezin from the very beginning, as most timepoints of the counselling sessions coincide with the time points of the Kind&Gezin vaccine scheme (postpartum week 6, week 8, week 12, 6 months). We will organize the coaching in a "mother and baby friendly" community-based setting or in the hospitals, as preferred by the mothers. Pregnancy coaching sessions: take place in hospital, at the time of the three planned ultrasound scans. By consequence, the applied methodology can be applied as such at the moment of global utilisation in Flanders. |
| Measure | Description | Time Frame |

| prevalence of participants with at least one of the following four complications: pregnancy-induced hypertension, gestational diabetes mellitus, caesarean section, large-for-gestational age baby | The existence of pregnancy-induced hypertension and gestational diabetes mellitus are assessed during pregnancy. Whether the 2nd pregnancy results in a caesarean section and large-for-gestational-age baby will be known at the time of delivery 2nd pregnancy. Therefore, the primary outcome of prevalence of participants with pregnancy and birth-related complications is assessed at the time of delivery 2nd pregnancy. | at the time of delivery 2nd pregnancy (max pregnancy duration 44 weeks) |

| Rate of women who returned to their pre-pregnancy weight | at 6 months, at 12 months, at 18 months .... till delivery 2nd pregnancy |
