Fit4Two: Feasibility, acceptability and efficacy of a tailored eHealth lifestyle behaviours intervention for pregnant women integrated into clinical practice – a randomised controlled trial

Participants complete a 15-20 minute online questionnaire on physical activity and nutritional levels before pregnancy and current physical activity and nutritional behaviours via an iPad whilst waiting in the reception area prior to their appointment with their practitioner. Participants will be screened for eligibility during this time and data collected at this time point will include participants physical activity and nutritional behaviours before pregnancy and at present, as well as basic socio-demographic details including age, gestational age, weight and height to determine BMI, education, income and relationship status. Upon completing the baseline assessment, a personalised and tailored 'Health Behaviours Report' will be automatically generated (based on the participants self-reported physical activity and nutritional behaviours), and print from a printer that is located in the clinics reception area. This report is then forwarded onto the appropriate practitioner to embed into the participants consultation. At the completion of the consultation, participants are then instructed to collect additional information about the Fit4Two project from the reception area, where they are then provided with an information pack that includes a Fitbit device to wear throughout the duration of the program, as well as additional information about the Fit4Two project. The Fit4Two Website: The Fit4Two website consists of eight (8) weekly behaviour change modules, guided by the Social Cognitive Theory (SCT) based on improving physical activity and nutritional behaviours among pregnant women such as developing social support networks and overcoming perceived barriers. At the completion of each module, participants are provided with tailored feedback that is based on their responses to the survey questions that participants answer at the beginning of each weekly module. Each of these modules apply behaviour change constructs that have previously been identified as effective to increasing physical activity and nutrition among pregnant women. In addition to the weekly module, participants will also receive access to a weekly action planning tool, which guides participants in setting detailed SMART goals and an action plan for their physical activity and nutritional behaviours over the coming week. Throughout the project, participants in the intervention group will also be provided with 3 x 20 minute virtual consultations with the project leader. The sessions can be conducted via phone or computer and will be hosted through the conferencing program Zoom. The tailored advise is developed and generated by the Fit4Two web-based software (based on algorithms and coding), and developed in conjunction with behaviour change and exercise and nutrition during pregnancy experts.
