Adherence
A behavioral weight loss maintenance intervention is cost-effective for individuals with BMI ≥ 28 kg/m² if the per-person cost is ≤ £104.64, yielding a maximum justifiable cost at an ICER of £20,000 per QALY.
For a person with a BMI over 28, a behavioral weight loss maintenance program is considered cost-effective by UK health standards if it costs less than approximately £105 per person. This program focuses on maintaining weight loss through diet and exercise advice, aiming to slow down the typical weight regain seen after initial weight loss.
The justifiable cost for a weight loss maintenance intervention at an ICER of £20,000 per QALY was £104.64 for an individual with a BMI of 28 or over
Why this rating
Based on a meta-analysis of RCTs and a validated health economic model, but relies on extrapolation of long-term weight regain.
