Abstract

![CDATA[Background: Partial meal replacement (PMR) (one or two per day) is an effective tool for short-term weight loss. Evidence and acceptability for longer term use in people with class 3 obesity (BMI>40kg/m ) are lacking. This study aimed to find the proportion of people using PMR in a multidisciplinary weight management program, and compare their weight loss with those not using PMR. Methods: A retrospective cohort study of all adult patients enrolled into a multidisciplinary weight management program in Sydney between March 2018-March 2019. PMR use and duration was extracted from patient records along with demographic data and weight. Results: Of 178 participants enrolled, 143 (80.3%) completed at least 6 months in the program. Of those, 66 (46.2%) had used PMR at any point during the program while 77 (53.8%) had not. There were no baseline differences in the PMR vs non-PMR groups in age (Mean±SD; 52.8±13.2 vs 52.6±13.9 years, p=0.93), gender (female% 66.7% vs 74%, p=0.34), weight (143.6±30.0 vs 140.3±33.0kg, p=0.53) or BMI (50.8±8.6 vs 51.0±9.2kg/m , p=0.87), or presence of co-morbidities including diabetes and hypertension. Both groups had significant weight loss at 12 months, with no difference between groups (PMR:9.4±7.6kg vs non-PMR:8.6±9.3kg, p=0.62). Although there was no major difference between groups in weight loss in the first 6 months (PMR:5.7±6.4kg vs non-PMR:7.3±5.5kg, p=0.18), there was significantly greater weight loss between 6 and 12 months in the PMR group compared to the non-PMR group (PMR:3.7±4.7kg vs non PMR:1.3±6.8kg, p=0.03). In the PMR group, there were no differences in baseline or weight loss in those that had used PMR for >3 months compared to <3 Months. Conclusion: In a multidisciplinary weight management program, PMR is a well-accepted tool for weight loss in people with class 3 obesity, and those on PMR seem more likely to continue losing weight after the initial 6 months.]]
