Abstract
Introduction
The correlation between body mass index (BMI) and utility in participants with obesity was assessed using health-related quality-of-life data collected in two weight loss intervention studies, SCALE and STEP 1.
Methods
Short Form Health Survey 36-Item (SF-36) scores from SCALE and STEP 1 were mapped to EuroQoL-5 dimensions-3 levels (EQ-5D-3L) using an established algorithm to derive utilities for the UK. SF-36 scores from STEP 1 were converted into Short Form 6 dimension (SF-6D) utilities for Portugal using the tool developed by the University of Sheffield. The correlation between baseline BMI and utility was assessed by multiple linear regression analyses, controlling for demographic and clinical parameters.
Results
A higher baseline BMI correlated with lower EQ-5D-3L and SF-6D utilities, although the trend was non-significant. Assuming linearity between BMI ranges 30–40 kg/m2, an additional unit of BMI correlated with 0.0041 and 0.0031 lower EQ-5D-3L scores in SCALE and 0.0039 and 0.0047 lower EQ-5D-3L and 0.0027 and 0.0020 lower SF-6D scores in STEP 1 for men and women, respectively.
Conclusion
In individuals with comparable demographic characteristics and weight-related comorbidities, a 1 unit change in BMI leads to a difference of up to 0.005 in utility indices.
Trial Registration
ClinicalTrials.gov identifiers: SCALE (NCT01272219) and STEP 1 (NCT03548935).
期刊介绍:
Advances in Therapy is an international, peer reviewed, rapid-publication (peer review in 2 weeks, published 3–4 weeks from acceptance) journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of therapeutics and interventions (including devices) across all therapeutic areas. Studies relating to diagnostics and diagnosis, pharmacoeconomics, public health, epidemiology, quality of life, and patient care, management, and education are also encouraged.
The journal is of interest to a broad audience of healthcare professionals and publishes original research, reviews, communications and letters. The journal is read by a global audience and receives submissions from all over the world. Advances in Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of all scientifically and ethically sound research.
