Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Healthy lifestyle information (improved diet, exercise, behaviour modification) during duration of pregnancy. Information will delivered in the form of 4 interactive education modules that focus on healthy eating, regular moderate exercise, identifying and removing barriers to healthy lifestyle behaviours and improving self efficacy. Participants will also receive detailed written information on the content covered in the education modules. The 4 education modules will be delivered between 14-16 to 26-28 weeks gestation (i.e. 1 module every 2-3 weeks).

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Sealed opaque envelops will contain group allocation information.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computer generated randomisation will be used to draw up an allocation schedule containing even numbers of control and intervention groups. The schedule will allow randomisation to control or intervention when recruitment occurs.

Summary
Brief summary
The primary aim of this study is to investigate the efficacy of simple lifestyle modification (healthy food choices and increased physical activity) in preventing excess weight gain during pregnancy (assessed 6 weeks postpartum). Secondary aims are to prevent prevalence of Gestational Diabetes Mellitus (GDM), identify barriers to healthy lifestyle choices and to provide an evidence base to inform future interventions targeting education and prevention of excess weight gain in the prevention of long-term obesity and prevention or treatment of Gestational Diabetes. The expected outcomes for this study include; 1/ Weight gain that is equal to, or below, recommended weight gain in the intervention group in comparison to the controls. 2/ Reduced prevalence of Gestational Diabetes and/or reduced intensity of treatment if diagnosis does occur in the intervention group. 3/ Lower incidence of increased foetal birth weight or macrosomia in the intervention group. 4/ Improved biological markers of health in the intervention group. 5/ Enhanced self-efficacy, motivation, mood and quality of life in the intervention group that persists long-term (1 year postpartum).
