Brief summary

The study aims to examine the effectiveness of a digital care guide offering support and information on diet, physical exercise and mental well-being on pregnancy weight gain among pregnant women with a BMI at 25 or above in a stepped-wedge cluster randomised study. The investigators hypothesise that access to a digital care guide focusing on diet, exercise and mental support, will support a reduced weight gain in pregnancy and improve the mental wellbeing of the participants.

Detailed description

Being overweight is the most prevailing health issue among women of reproductive age, and in Denmark, the proportion of pregnant women with a body mass index at or above 25 (BMI≥25) is nearing 40%. Women with overweight are at increased risk of complications in pregnancy and labor such as hypertensive disorders, gestational diabetes (GDM), and Cesarean section. Children of women with overweight more often have a high birthweight and are less likely to be breastfed, than children of women with a normal BMI. Both women and offspring, face an increased risk of overweight or obesity later in life. The risk of complications can increase if the pregnant woman gains excessive weight during pregnancy and conversely, reducing pregnancy weight gain can lower the risk of complications. However, more than half (60%) of pregnant women with overweight do not adhere to the pregnancy weight gain recommendations. In addition, only around one third of pregnant women with overweight meet the recommended daily levels of physical activity. This emphasizes a significant potential for prevention strategies focused on promoting healthy weight gain and physical activity during pregnancy. It has previously been established, that interventions focusing on physical activity and nutritional counselling can help women with overweight reduce excessive pregnancy weight gain. However, traditional lifestyle interventions can be both cost-intensive and resource-demanding to implement. With digital technologies, lifestyle interventions have potential to less resource-intensive testing and implementation. New research indicates that a digital application with information on a healthy diet and physical activity may have potential to help women with overweight reduce pregnancy weight gain. At Nordsjaellands Hospital and Slagelse Hospital respectively 37% and 49% of pregnant women are overweight with a BMI≥25. Pregnant women with overweight are offered standard care at Slagelse Hospital and at Nordsjaellands Hospital women with a BMI above 35 receive a minor supplement to standard care. However, both pregnant women and healthcare professionals request tailored and evidence-based care. The aim of the HealthyPregnancy study is to evaluate the effect of a digital care guide offering support and information on diet, physical exercise, and mental well-being on gestational weight gain. The digital care guide will be tested in a stepped wedge cluster randomized controlled trial including 450 pregnant women with a BMI at 25 or above. A secondary aim is to evaluate the effect of the digital care guide on pregnancy and diabetes outcomes among participating women diagnosed with gestational diabetes. HealthyPregnancy is carried out in collaboration between Center for Clinical Research and Prevention, Nordsjaellands Hospital and Slagelse Hospital.

Interventions

BEHAVIORALHealthyPregnancy

A digital care guide comprising of: 1. Information about diet, exercise and mental wellbeing in pregnancy. Presented in text, video and audio material featuring various healthcare professionals. 2. Online exercise. Access to live online structured physical exercise twice a week and to an off line library of exercise videos. 3. Chat function with possibility to chat safely with healthcare professionals. 4. Push-notifications reminding the participants of upcoming antenatal appointments. In addition an invitation to monthly café sessions focusing on e.g., mental health, parenting skills, breastfeeding and healthy lifestyle.

Mental well-beingAt inclusion, gestational week 35-37, eight weeks after delivery and one year after delivery.Mental well-being is measured with the World Health Organisation Five Well-being Index (WHO-5). The lowest score of the scale is 0 and the highest total score is 100. Higher scores indicating better mental well-being.
Symptoms of depressionAt inclusion, gestational week 35-37, eight weeks after delivery and one year after delivery.Symptoms of depression are measured with the Edinburgh Postnatal Depression Scale (EPDS) will be defined as cutoff score ≥ 13 and a cutoff score ≥ 10. The scale measures the intensity of common depressive symptoms on a 4-point Likert scale (0-3), where 0 indicates absence of depressive symptoms and 3 indicates the highest amount of depressive symptoms. The lowest score of the scale is 0 and the highest total score is 30.
