a) Values are presented as the weighted mean (standard error) or proportion (standard error) calculated considering the complex sampling design.
b) Values are presented as adjusted Wald test results or Pearson uncorrected chi-squared test results.
c) The amounts of aerobic activity are the sums of strenuous physical activity and moderate activity at work or in leisure time, and moving activity in daily life like walking or biking to go to work, school, shop, church and etc.
d) These categorical variables of aerobic exercise were created by quartile in amounts calculated with METs-min/week units.
