Purpose: The purpose of this study was to assess the association of organizational factors with work-related sleep problems (WRSP) among Korean workers. Methods: The data were derived from the First Korean Working Conditions Survey conducted in 2006 with a representative sample of the Korean working population (n = 10,039). Results: The overall prevalence of WRSP was 5.1 % (95 % confidence interval (CI) 4.7-5.5). Those who experienced sexual harassment at work (adjusted odds ratio (aOR) 3.47: 95 % CI 1.77-6.81), discrimination due to sex (aOR 2.44: 95 % CI 1.36-4.36) or age (aOR 2.22: 95 % CI 1.52-3.23), violence at work (aOR 1.98: 95 %CI 1.06-3.68), threat of violence (aOR 1.96: 95 %CI 1.05-3.66), poor work life balance (aOR 1.78: 95 % CI 1.44-2.20), low job satisfaction (aOR 1.69: 95 % CI 1.37-2.09), high cognitive (OR 1.64: 95 %CI 1.32-2.03) and emotional (aOR 1.53: 95 %CI 1.22-1.91) demands, job insecurity (aOR 1.32: 95 % CI 1.07-1.63), and high work intensity (aOR 1.55: 95 % CI: 95 %CI 1.25-1.92) had an increased risk of WRSP compared to their respective counterparts (p < 0.01). Low social support was not significantly associated with WRSP (aOR 0.88: 95 % CI 0.67-1.15). Conclusion: The results revealed that poor psychosocial working conditions may be related to a high prevalence of WRSP among representative Korean workers.
