Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the PreLiFe RCT is to assess the effects of a new mobile preconception lifestyle programme (PreLiFE-programme) for couples undergoing IVF. Couples about to start IVF will be randomized between an attention control programme or the PreLiFe-programme for 12 months or until an ongoing pregnancy is confirmed by ultrasound.This study will examine whether the PreLiFe-programme results in a higher cumulative ongoing pregnancy rate within 12 months as compared to an attention control programme. Secondary outcomes include changes in diet, physical activity, personal wellbeing, body mass index, waist circumference, quality of life and other reproductive outcomes including clinical pregnancy and time to pregnancy. Additionally, the partners' support and the feasibility of the PreLiFe-programme will be evaluated.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Introduction: Infertility and in vitro fertilization (IVF; with or without intracytoplasmic sperm injection, ICSI) result in considerate emotional and financial burden. Increasing evidence suggests that lifestyle factors, including diet, physical activity and personal wellbeing, are associated with IVF-success rates. So far, IVF is not routinely combined with a lifestyle programme. The PreLiFe randomized controlled trial (RCT) will assess the effects of a new mobile preconception lifestyle programme (PreLiFe-programme) in couples undergoing IVF.

Methods and analysis: A multicentre RCT will include heterosexual couples about to start IVF (with or without ICSI) in Belgian fertility clinics. IVF-Couples will be randomized between an attention control programme or the PreLiFe-programme for 12 months or until an ongoing pregnancy is confirmed by ultrasound. The attention control programme includes a mobile application with treatment information (i.e. appointments and medication instructions) in addition to standard care. The PreLiFe-programme includes a mobile application with the same treatment information in combination with a lifestyle programme. This new lifestyle programme includes tailored advice on diet and physical activity and mindfulness exercises in combination with text messages and telephone interaction with a lifestyle coach. The primary outcome of this RCT is the cumulative ongoing pregnancy rate within 12 months after randomisation. Secondary outcomes include changes in diet, physical activity, personal wellbeing, body mass index, waist circumference and quality of life measured with self-reported questionnaires and physical assessments and changes in other reproductive outcomes including clinical pregnancy and time to pregnancy. Additionally, the partners' support and the feasibility (use and acceptability) of the PreLiFe-programme will be evaluated using self-reported questionnaires and app-based tracking. Analysis will be according to intention to treat.

Ethics and dissemination: This study has been approved by the Medical Ethical Committee of the Leuven University Hospital (Belgium) and of the other recruiting clinics. The findings of this RCT will be disseminated through presentations at international scientific meetings and peer-reviewed publications.

Due to the worldwide Covid-19 pandemic, we had to stop recruiting new patients and stop studying patients who were in the midst of their 12 months study period. This was inevitable as all Belgian fertility clinics stopped offering IVF as of March 13th 2020 for a (not predefined) period. Patients who had been randomized, but were still ongoing in the trial at that time needed to be censored. Based on statistical advise, we changed therefore our primary outcome analysis from cumulative ongoing pregnancy rate within 12 months after randomisation to time to ongoing pregnancy in order to be able to use the data of the many study patients who were in the midst of their 12 months study period.

PreLiFe-programme

A Mobile Preconception Lifestyle programme

Group Type EXPERIMENTAL

PreLiFe-programme

Intervention Type BEHAVIORAL

The intervention group will receive a mobile preconception lifestyle programme (the PreLiFe-programme) in addition to standard care for 12 months or until an ongoing pregnancy is confirmed by ultrasound. The PreLiFe-programme includes a mobile application (PreLiFe-app) with the same treatment information as the attention control group in combination with a lifestyle programme. This new lifestyle programme includes tailored advice and skills training on diet and physical activity and mindfulness exercises. Additionally couples will be offered interaction with a health care provider through text messages and telephone interaction following the concept of blended care.

Attention Control Programme

Intervention Type BEHAVIORAL

The standard care serving as control for this intervention is fertility treatment i.e. IVF with or without ICSI according to local protocols for infertility patients. This implies no guidance on lifestyle. However, to have attention control the control group will receive an attention control programme. The attention control programme includes a mobile application (app) with treatment information including medication instructions, reminders of injection of human Chorionic Gonadotropin (hCG) and time of fertility treatment appointments for 12 months or until an ongoing pregnancy is confirmed by ultrasound.
