Organizational factors associated with work-related sleep problems in a nationally representative sample of Korean workers

Abstract

PurposeThe purpose of this study was to assess the association of organizational factors with work-related sleep problems (WRSP) among Korean workers.MethodsThe 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).ResultsThe 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).ConclusionThe results revealed that poor psychosocial working conditions may be related to a high prevalence of WRSP among representative Korean workers.

Psychosocial work factors and sleep problems: findings from the French national SIP survey

“…Emotional demands and tensions with the public were associated with sleep problems in our cross-sectional analysis. These findings are in line with the results by Park et al (2013) who reported an association between emotional demands and work-related sleep problems in a cross-sectional sample of Korean workers. Work-life imbalance was found to be associated with sleep outcomes mostly in our cross-sectional analyses.…”

“…Job insecurity was associated with sleep problems in model 1 in our cross-sectional analysis. Two previous studies reported an association between job insecurity and sleep outcomes in cross-sectional samples of Korean workers (Kim et al 2011;Park et al 2013).…”

“…Nevertheless, the authors of this review suggest that using all prospective studies (not only high-quality prospective studies), there may be moderate evidence for the effects of low social support, effort-reward imbalance and organizational injustice on sleep. Studies, that were not all prospective, found that low reward (Eriksen et al 2008;Fahlen et al 2006;Kim et al 2011;Kudielka et al 2004), role conflict (Eriksen et al 2008;Knudsen et al 2007), emotional demands (Park et al 2013), job insecurity (Kim et al 2011;Park et al 2013) or work-family conflicts (Lallukka et al 2010(Lallukka et al , 2014Park et al 2013) were associated with sleep outcomes. These factors may be considered as emergent psychosocial work factors in association with sleep outcomes.…”

Psychosocial work characteristics and sleep quality: a systematic review of longitudinal and intervention research

“…Indeed, several studies have found a relation between work-related psychosocial stressors (ie, high workload, job strain, cognitive and emotional job demands, job insecurity, bullying) and poor sleep quality (18)(19)(20)(21)(22)(23). Likewise, positive psychosocial work factors (ie, social support, job control, organizational justice) have been linked to favorable sleep quality (19,22,24).…”

“…There are, however, quite a number cross-sectional studies providing support for an association between work stress and impaired sleep 13−16) . For instance, high work strain, defined as the combination of high work demands and low job control, has been associated with a higher prevalence of disturbed sleep 13) and more sleep complaints 14,15) , and high cognitive and emotional demands at work have been associated with an increase in sleep problems 16) . Another study examining the associations between work strain and sleep quality found that the most important correlates of sleep quality were not job demands or job control but the inability to stop thinking about work 17) .…”
