Purpose
To examine the relation of work type with health-related quality of life (HRQoL) in healthy workers.
Methods
We cross-sectionally examined 4427 (3605 men and 822 women) healthy workers in Japan, aged 19–69 years. We assessed HRQoL based on scores for five scales of the SF-36. Multiple regression was applied to examine the relation of work type (nighttime, shift, day to night, and daytime) with the five HRQoL norm-based scores, lower scores of which indicate poorer health status, adjusted for confounding factors, including sleeping duration.
Results
Shiftwork was inversely related to role physical [regression estimate (β) = −2.12, 95 % confidence intervals (CI) −2.94, −1.30, P < 0.001], general health (β = −1.37, 95 % CI −2.01, −0.72, P < 0.001), role emotional (β = −1.24, 95% CI −1.98, −0.50, P < 0.001), and mental health (β = −1.31, 95% CI −2.01, −0.63, P < 0.001) independent of confounding factors, but not to vitality. Day-to-nighttime work was inversely related to all the five HRQoL subscales (Ps 0.012 to <0.001).
Conclusion
Shiftwork was significantly inversely related to four out of the five HRQoL, except for vitality, and day-to-nighttime work was significantly inversely related to all five HRQoL, independent of demographic and lifestyle factors.
