Maternal obesity


The Lifestyle Course (TLC) is innovative as it is a multi-component intervention that addresses a complete healthy lifestyle for the whole family and combines theory-based behaviour change techniques (social cognitive theory) with a healthy eating, physical activity and well-being intervention. TLC is informed by the findings of a feasibility study (N=259) highlighting what intervention aspects were acceptable and suitable to pregnant women with a BMI of 30kg/m2 or more. TLC runs for two hours per week for 10-weeks and women must be between 12 and 28 weeks gestation. A multi-disciplinary team and a range of experts designed the intervention and tested it for use in a feasibility study with pregnant women with a BMI of 30kg/m2 or more in Greater Manchester.

Control group - routine maternity care. The 36 women who are randomised to the control arm of the intervention will continue to receive standard maternity care within the NHS trust that they were recruited from (Royal Bolton Hospitals NHS Foundation Trust and The Pennine Acute Hospitals NHS Trust). Their care will follow the individual hospital’s maternity care guidelines and care pathways according to their antenatal booking BMI.

TLC group - The women who are randomised to the intervention arm and are offered the opportunity to attend the 10-week TLC will receive the same maternity care within their NHS trust. Any contact made with the research team by ‘control’ women will be noted, as will any non-research questions that they ask to the research midwives in the data collection sessions.
