Effects of the ‘Croi CLANN’ structured lifestyle modification programme on anthropometric and metabolic characteristics in severely obese adults

Introduction: Lifestyle modification is fundamental to obesity treatment, but few studies have described the effects of structured lifestyle programmes specifically in bariatric patients. We sought to measure changes in anthropometric and metabolic characteristics in this cohort after participation in a nurse‐led, group‐based, fully supervised eight week programme, incorporating tailored weekly exercise sessions and educational workshops. Methods: Weight, height, waist circumference, blood pressure, HbA1c, fasting glucose and lipid profiles as well as functional capacity (Chester Step Test) and questionnaire‐based anxiety and depression scores before and after the programme were compared in per‐protocol analyses using a paired t‐test. Results: Of 109 bariatric patients enrolled, 100 completed the programme. Mean age was 48.8 ± 11.9 years. 38% were male. Results are shown in the table. Data are presented as means ± SD. There were no changes in blood pressure, fasting glucose or HbA1c (data not shown). Conclusion: Bariatric patients completing an eight week, nurse‐led structured lifestyle programme had improved adiposity, fitness, lipid profiles and mental health, but not blood pressure or glycaemia. Further assessment of this programme in a pragmatic randomized controlled trial is warranted. (Table presented).
