Evaluation of the 'Live Life Better Service', a community-based weight management service, for morbidly obese patients

Abstract

Background There is a limited evidence on the effectiveness of lifestyle interventions in achieving and maintaining a significant level of weight loss in morbidly obese patients. This study evaluated the impact on weight loss and psychological well-being of a community-based weight management service for morbidly obese patients [body mass index (BMI) 35 with related co-morbidities or BMI .40] in Derbyshire county. Methods Five hundred and fifty-one participants entered the service since 2010, and 238 participants were still active within the service or had completed the 2-year intervention in April 2013. A one-group pre-post design was used to determine average weight loss (kg) and impact on mental health and well-being [using the validated clinical outcomes of routine evaluation-outcome measure (CORE-OM) questionnaire] among participants. Measurements were recorded at baseline, 12 weeks, 24 weeks, 1 year, 18 months and 2 years, and significance (P 0.05) was determined using the paired sample t-test. Results Statistically significant weight loss was recorded at each measurement point for those participants who remained engaged with the service (4.9 kg weight loss at 12 weeks to 18.2 kg at 2 years). There was a significant positive impact on psychological well-being demonstrated by CORE-OM score. Conclusions Findings show clinically and statistically significant weight loss among participants with improvements in physical and mental health.
