Abstract


OBJECTIVES
This study was conducted to investigate the relationship between night work and cardiovascular diseases among wage workers in Korea.
METHODS
The study was based on the 3rd Korean Working Conditions Survey (KWCS; 2011). This study included 29,711 wage workers. We used the chi-squared test and logistic regression to examine the association between cardiovascular diseases and night work and cumulative night work.
RESULTS
Among all of the paid workers, 12.5% reported doing night work > or = 1 day per month. Night work was significantly associated with an increased risk of cardiovascular diseases (odds ratio [OR] 1.58, 95% confidence interval [CI] 1.11-2.25). Also, compared to the group that did not do night works, the group with higher cumulative night work demonstrated an increased risk for cardiovascular diseases (OR 1.81, 95% CI 1.19-2.74).
CONCLUSIONS
This study suggests that night work is significantly associated with cardiovascular diseases.
