Higher baseline BMI (30–40 kg/m²) correlates with lower health-related quality of life (utility indices), but the effect size is small (up to 0.005 per unit BMI) and often not statistically significant, suggesting BMI alone does not explain HRQoL differences.

While higher BMI is associated with slightly lower health utility scores, the impact is small and often not statistically significant. Do not assume your quality of life is defined by your BMI alone. Focus on managing specific comorbidities, age-related changes, and mental health, as these appear to be stronger drivers of your daily well-being than BMI itself.

a higher baseline BMI correlated with lower EQ‑5D‑3L and SF‑6D utilities, although the trend was non‑significant... an additional unit of BMI, within the range of 30–40 kg/m2, was consistently correlated with an up to 0.005 worsening in the utility index... BMI alone may not explain the differences in participants’ HRQoL

Why this rating

Large sample sizes (N=1755 and N=1961) from pivotal randomized controlled trials (SCALE and STEP 1), though the specific correlation was not statistically significant in the primary model.
