| Project Title | Developing a Weight Loss Programme for Couples Seeking Fertility Treatment (WELCOME): A multi-methods needs assessment |
| Project Description | Obesity can negatively impact fertility outcomes for both women and men, yet within the fertility context, studies have focused solely on reducing the weight of the woman seeking pregnancy and have not included the partner in the weight loss attempt. A couple-based approach to weight loss, could improve reproductive outcomes in couples experiencing fertility issues. This thesis explores the feasibility and acceptability of delivering a couple-based weight loss intervention to women with a BMI 30-40 kg/m2 and their partners. A systematic review of the literature revealed no recent trials involving men or couples. A three-armed randomised controlled feasibility trial involving a commercial weight loss programme (Slimming World) was developed and delivered. Feasibility was measured through study recruitment and retention rates and intervention acceptability was explored through a built in process evaluation. Of 71 couples who expressed an interest, 59.1% were screened and of these, 61.9% were eligible and recruited to the weight loss intervention. Retention was high with 80.9% of couples remaining in the study for 24 weeks. Women in all three groups significantly reduced their weight from baseline to study end, however, there was no difference in weight loss between the three trial arms. The delivery of the Slimming World programme was heavily disrupted by Covid. Interview data revealed partners struggled to provide social support for the woman, suggesting training around ways to improve the provision of social support could be beneficial. It appears feasible to offer a couple-based weight loss programme in the fertility context. However, the acceptability around the use of Slimming World as the weight loss provider remains uncertain. Alternative intervention components are proposed and discussed and further feasibility work is recommended before the development of a larger scale trial. |
