Use of the App

The Slimmer Zwanger app serves as a tool to support You through coaching in improving your nutrition, lifestyle habits and mental health (wellbeing) before and during pregnancy. The coachingprogram aims to increase the chance of pregnancy, improve pregnancy outcomes, and enhance the health and wellbeing of You and your (unborn) child. Additionally, the program acts as a tool to facilitate a lifestyle consultation with your treating physician. You remain personally responsible for following the advice provided by the program.

As a participant, You complete questionnaires to map your (un)healthy nutritional and lifestyle habits as well as your mental health. Based on this data, a tailored program is set up for You on your mobile phone to enhance your knowledge and skills, enabling you to change unhealthy habits and maintain healthy ones.

The content of the program is based on the experiences and scientific knowledge of the web application www.slimmerzwanger.nl (2012-2024). It has also been enriched with the latest insights contributed by users, researchers, (para)medical professionals, and behavioral experts. Erasmus MC is not liable for any direct or indirect damage that may result from the use of the information provided. No rights or claims can be derived from the app's content.

The app's coachingprogram involves answering questions, reading information and advice tailored to your (un)healthy nutrition, lifestyle habits, mental health, and pregnancy status. Additional coaching features include journals where you can track your goals and mood, as well as screenings for the safe use of medications.
