Table S1. Odds ratios for metabolic syndrome associated with working hours among non-shift male workers, Japan, 2009. As a supplementary analysis, we restricted the subjects to non-shift workers to examine whether the associations between long working hours and metabolic syndrome were modified by shift work. Table S2. Odds ratios for metabolic syndrome associated with working hours stratified by age (<45 years vs. ≥45 years) among men in Japan, 2009. As a supplementary analysis, we stratified the subjects by age (<45 years vs. ≥45 years). Table S3. Odds ratios for metabolic syndrome associated with working hours stratified by age (<50 years vs. ≥50 years) among men in Japan, 2009. Description of data: As a supplementary analysis, we stratified the subjects by age (<50 years vs. ≥50 years).
