Background and study aims
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.

Who can participate?
90 eligible pregnant women in the UK

What does the study involve?
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.

What are the possible benefits and risks of participating?
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.

Where is the study run from?
Loughborough University (UK)

When is the study starting and how long is it expected to run for?
June 2022 to June 2024

Who is funding the study?
National Institute for Health and Care Research (NIHR) via a Research Professorship to Professor Amanda Daley and Loughborough University (UK)

Scientific titleA randomised controlled trial to investigate the feasibility and acceptability of Snacktivity™ in pregnant women
Study acronymSUNNY
Study objectivesThe aim of the SUNNY study is to undertake a randomised feasibility trial, with nested qualitative interviews, to assess the feasibility and acceptability of the Snacktivity™ intervention during pregnancy.
Ethics approval(s)Approved 19/07/2023, South Central - Hampshire B REC (2 Redman Place, Stratford, London, E20 1JQ, United Kingdom; 020 7104 8289 hampshireb.rec@hra.nhs.uk), ref: 23/SC/0159
Health condition(s) or problem(s) studiedReproductive health and childbirth
InterventionParticipants will be randomised to receive either standard physical activity advice during pregnancy or encouragement to achieve the recommended physical activity levels for pregnancy via Snacktivity™. For the intervention group, Snacktivity™ will be promoted with a physical activity tracker (Fitbit watch) and access to the SnackApp. Both resources will help participants monitor their physical activity, activity snacks, and steps each day. The researchers will measure physical activity at the start of the study and at 36 weeks gestation for both the intervention and control group; however, steps, light-to-vigorous physical activity, moderate-to-vigorous physical activity, and activity snacks will be monitored for the intervention group throughout the 24-week intervention period.

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. These physical activity snacks should last between 2-5 minutes and can include activities such as rushing for a bus, getting off the bus a stop earlier and walking to the destination, walking over to a colleague instead of sending an email when at work, taking the stairs instead of the lift, and calf raises whilst brushing their teeth. The Snacktivity™ approach also aims to reduce the time people spend sitting as a result of moving more frequently throughout the day, which can also have important benefits for health, particularly during pregnancy.
Intervention typeBehavioural
Primary outcome measureThe feasibility of a subsequent phase III randomised controlled trial (RCT) according to pre-specified progression criteria will be assessed at the final follow-up. The researchers are primarily interested in whether:
1. The trial is appealing measured using the number/percentage of people randomised against the recruitment target of 90 participants
2. The Snacktivity™ intervention is acceptable through assessing Snacktivity™ adherence measured using a physical activity tracker (Fitbit watch) and SnackApp data
3. Participant attrition measured using loss to follow-up in [the study notes]

The feasibility and acceptability will also be assessed with participant interviews (intervention group only) and healthcare practitioner interviews on the indicators after the final follow-up:
1. Intervention delivery
2. Participant satisfaction, enjoyment, and intervention acceptability
3. Intervention sustainability
Secondary outcome measures1. Total physical activity (light-to-vigorous activity and steps per day) measured using a research-grade wrist-worn accelerometer at baseline and 36 weeks gestation
2. Moderate-to-vigorous physical activity measured using a research-grade wrist-worn accelerometer at baseline and 36 weeks gestation
3. Sedentary time measured using a research-grade wrist-worn accelerometer at baseline and 36 weeks gestation
4. Gestational weight gain measured at baseline and 36 weeks gestation
5. Depression measured using the Edinburgh Postnatal Depression Scale at baseline, 26- and 36 weeks gestation
6. Fatigue measured using the Multidimensional Assessment of Fatigue at baseline, 26- and 36 weeks gestation
