*

Cardiorespiratory fitness (CRF) cutoffs based on age (in 10‐year strata) and sex‐specific distribution in 66 943 participants free from cardiovascular disease (CVD) and cancer at baseline and with at least 2 years of observation time.

Healthy dietary pattern is based on meeting at least 2 of 3 healthy eating targets related to food types: (1) ≤3 weekly servings of red meat and ≤1 servings per week of processed meat; (2) ≥2 servings per week of fish including at least 1 with oily fish; and (3) ≥5 servings per day of fruits and vegetables.
