How scoring works
Baseline by age group + components: ultra‑processed share (convex penalty), diet‑quality protection, L‑shaped sleep penalty below ~7.5 h, shift‑work dose with step‑ups (>5 and >10 years) and sex/BMI modifiers, stress–eating interactions, child GDM adjustment, and older‑adult sarcopenic‑obesity screen. Scores map 0–100 (propensity, not diagnosis).
