Many studies show that pregnant women do not achieve 150 minutes of moderate-intensity physical activity per week, which is the recommended guideline. To date, there is a large amount of research describing the benefits and barriers of physical activity during pregnancy, but very few studies have looked at how to best support pregnant women and their ability to reach and maintain their physical activity levels. Through participation in physical activity during pregnancy, women have decreased risk of complications such as high blood pressure, excessive protein in their urine, too much weight gain and gestational diabetes, as well as reduced anxiety and feelings of depression. To try and help women reduce their chances of pregnancy-related complications, we plan to conduct the SUNNY study which aims to test the feasibility and acceptability of an approach we have called Snacktivity™ during pregnancy. Snacktivity™ is based on the idea that small, frequent doses of physical activity throughout the day, called 'physical activity snacks', can help people accumulate at least 150 minutes of moderate-intensity physical activity per week.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.  

The recruitment start and end dates are as follows:

21 Jul 2023 21 Jan 2024

Participants will be randomly allocated to receive either the Snacktivity™ intervention programme or a standard antenatal care programme. Participation in this study will take place from when women are around 10-16 weeks pregnant until they are 36 weeks pregnant. In addition to receiving standard antenatal care, participants in the Snacktivity™ intervention group will receive access to a mobile phone application called the SnackApp and a physical activity tracker (Fitbit watch), which will measure their physical activity snacks throughout the week.

You may not be able to take part if:


1. Post-natal or non-pregnant women2. Pregnant women past 16 weeks gestation3. Severe sickness (hyperemesis gravidarum)4. Currently taking part in a different research study that involves physical activity or other lifestyle behaviours5. BMI >50 kg/m26. Inability or unwillingness to provide consent7. Women whose GPs feel it is inappropriate for them to take part8. Cannot speak and read standard English9. No access to an email address10. No access to a smartphone with Bluetooth capability for hosting mobile applications (Apple iOS 10.0+ and Android OS 4.0+)11. Complete > 150 minutes of physical activity per week pre-pregnancy (as measured by the EVS)


Below are the locations for where you can take part in the trial. Please note that not all sites may be open.

It is hoped that the Snacktivity™ intervention will encourage pregnant women to be more physically active, which may help reduce pregnancy-related complications. The researchers do not expect any risks from taking part in this study.


The study is sponsored by Loughborough University and funded by National Institute for Health and Care Research.
