This study examined the effectiveness of a sports-club led X-PERT Diabetes Programme, measuring changes to participants' physical condition, knowledge of diabetes, psychological well-being, activity level, diabetes self-management and participants' rating of the programme. In this mixed-method, repeated measures evaluative study, data were gathered at baseline (T0), 6 weeks (T1) and 6 months (T2) using the Diabetes Health Profile (DHP), General Practice Physical Activity Questionnaire (GPPAQ), Diabetes Empowerment Scale -Short Form (DES-SF), Participant Evaluation Questionnaire (PEQ), and focus groups. Over three years, 260 individuals with type 2 diabetes provided data for the evaluation. The sports-club led X-PERT Diabetes Education Programme was successful in achieving its targets with improvement in clinical outcomes including significant reductions in BMI, waist circumference, total cholesterol, LDL cholesterol, triglycerides and glycated haemoglobin by T2. Positive changes were also evident in relation to participants' health profile, self-management and empowerment. This study illustrates the important role that European sports stadia can play in community health through delivering targeted programmes beyond general health promotion activities.
