The increasing burden of obesity generates significant socioeconomic impacts for individuals, populations, and national health systems worldwide. literature on cost-effectiveness obesity-related interventions prevention treatment moderate to severe indicate that bariatric surgery presents high costs associated with effectiveness in improving status referring certain outcomes; however, there is a lack robust evidence at an individual-level estimation its multiple outcomes related comorbidities.The study encompasses single-centre retrospective longitudinal analysis patient-level data using micro-costing technique estimate direct care pre-and post-bariatric surgery. Data from 114 patients who had the Hospital Clinics University Sao Paulo during 2018 were investigated through interrupted time-series generalised estimating equations marginal effects, including information patients' characteristics, lifestyle, anthropometric measures, hemodynamic biochemical exams, utilisation resources screening (180 days before) follow-up after) surgery.The preliminary statistical showed presented improvement, except cholesterol VLDL, overall increased after intervention. However, time series rise attributable cost surgery, followed by statistically decrease post-intervention costs. Changes also general, LDL, leading improvements intervention.Trends compared trends pre-intervention, resulting reduced obesity.
