Differences in cardiorespiratory fitness, physical activity, and pulmonary function across occupational groups and educational levels: a cross-sectional study

Among men, blue-collar workers reported higher self-reported weekly PA than white-collar workers, with no significant differences in estimated <i>V</i>O_2max. Among women, blue-collar workers did not report higher self-reported PA but had lower estimated <i>V</i>O_2max than white-collar women. These differences are small and should be interpreted cautiously.
