Reference

Reference

  1. LPA, MPA, and VPA were mutually adjusted; all adjusted for age, sex, ethnicity, education, deprivation index, sleep duration, smoking, alcohol intake, dietary intake of fruits/vegetables, red meat, processed meat, and oily fish
  2. HR hazard ratio, MPA moderate-intensity PA, VPA vigorous-intensity PA, PPF preventable fraction of the population
  3. aPFP estimated the fractions of all incident affective disorders that could have been prevented if the individuals in those PA categories were as active as the reference group
