“…9, 18 Kang et al (2012) reported a 37 percent increase in the odds of CVD among those exposed to long work hours (the definition of which varied by study) compared to those unexposed (95% CI: 1.11 – 1.70), which was not influenced by age, geographical location, or study year. A subgroup analysis of participants working ≤55 hours per week attenuated the relationship between work hour duration and CVD (OR: 1.28; 95% CI: 0.85 – 1.91).…”

“…A subgroup analysis of participants working ≤55 hours per week attenuated the relationship between work hour duration and CVD (OR: 1.28; 95% CI: 0.85 – 1.91). 18 Virtanen et al (2012) demonstrated that working long hours (definition varied by study) was associated with an estimated 80 percent increase in the risk of CVD (RR: 1.80; 95% CI: 1.42 – 2.29). In a series of subgroup analyses, they reported that studies defining LWH as a threshold above 50 WH/w had substantially higher RRs than those studies defining LWH as a threshold equal to or below 50 WH/w (RR≤50 WH/w: 1.41; 95% CI: 1.14 – 1.74 vs. RR>50WH/w: 2.37; 95% CI: 1.56 – 3.59).…”

“…11 Substantial evidence exists that working long hours is associated with many CVD-related risk factors (e.g., hypertension, 12, 13 heart rate variability, 14 smoking, 15 physical inactivity, 15 stress 15, 16 and depression 17 ), and it has been suggested that increasing work hour durations may have a dose-response relationship with CVD. 9, 18 …”

Objectives To examine the presence of a dose-response relationship between work hours and incident cardiovascular disease (CVD) in a representative sample of U.S. workers. Methods Retrospective cohort study of 1,926 individuals from the Panel Study of Income Dynamics (1986–2011) employed for at least 10 years. Restricted cubic spline regression was used to estimate the dose-response relationship of work hours with CVD. Results A dose-response relationship was observed in which an average workweek of 46 hours or more for at least 10 years was associated with increased risk of CVD. Compared to working 45 hours per week, working an additional 10 hours per week or more for at least 10 years increased CVD risk by at least 16%. Conclusions Working more than 45 work hours per week for at least 10 years may be an independent risk factor for CVD.

“…Although our results shows significant associations only in longest working-hour group, these results are in line with those of previous studies, which reported an association between long working hours and CHD. A meta-analysis study concluded that longer working hours was related with the risk of CHD with an OR of 1.37 [14]. Another meta-analysis of 4 prospective studies reported a relative risk of 1.39 for long working hours on CHD [4].…”

BackgroundRecently, the emergence of long working hours and the associated conditions such as coronary heart disease (CHD) and stroke have gained attention. The aim of this study was to investigate the association between long working hours and the 10-year-risk of CHD and stroke, estimated by Jee’s health risk-appraisal model for ischemic heart disease.MethodsWe analyzed data from Koreans who randomly enrolled in Korean National Health and Nutrition Examination Survey 2008–2012 and finally included 13,799 participants. The participants were classified as per their working hours: 0–30 h/week, 31–39 h/week, 40 h/week, 41–50 h/week, 51–60 h/week, 61–70 h/week, 71–80 h/week, and >80 h/week. The risks for CHD and stroke were determined using Jee’s health risk-appraisal model. Multiple logistic regression was used to analyze the association between working hours and 10-year risk for CHD.ResultsThe 10-year risks for CHD and stroke were significantly and positively associated with working hours in both men and women. Furthermore, higher risks for CHD and stroke were associated with longer working hours in women.ConclusionLong working hours are significantly associated with the risks of CHD and stroke, estimated by Jee’s health risk-appraisal model. This study suggests the need for proper management of working hours to reduce CHD risk and stroke risk in the Korean population.Electronic supplementary materialThe online version of this article (doi:10.1186/s40557-016-0149-5) contains supplementary material, which is available to authorized users.

“…Noise and vibration have been studied mostly separately without adjustment for other occupational factors related to the CVD, such as occupational smoke and dust [19], heavy lifting [20], extreme temperatures [21], working hours [22] and shift work [23]. Furthermore, the evidence from Bulgaria is largely insufficient, outdated, and lacks adequate adjustments of the models to draw conclusions about the risk nowadays.…”

Background: Cardiovascular disease (CVD) is the main mortality cause worldwide. Noise and vibration are considered to be occupational risk factors, but little is known about their cardiovascular effects in Bulgaria in terms of gender and various professional groups. The aim of this study has been to investigate the risk of prevalent CVD, associated with occupational noise and vibration exposure. Material and Methods: We conducted a secondary analysis of the data from 3 waves of the European Working Conditions Survey (EWCS) 2001-2010 -a nationally-representative cross-sectional questionnaire survey covering 3149 workers aged ≥ 15 years in Bulgaria. Data on self-reported heart disease were linked to self-reported occupational noise and vibration, adjusting for other factors. Results from the 3 waves were pooled together using the inverse variance heterogeneity (IVhet) meta-analysis. Results: For noise, the risk was elevated among women (relative risk (RR) = 1.26, 95% confidence interval (CI): 0.53-3.01), but not men (RR = 0.49, 95% CI: 0.14-1.65). Long-term workers had RR = 1.01, 95% CI: 0.60-1.69. For vibration, the risk was increased in all participants. It was higher among men (RR = 2.56, 95% CI: 1.60-4.09) than it was among women (RR = 1.32, 95% CI: 0.77-2.27). Among long-term, industrial, and service workers it was RR = 1.56, 95% CI: 1.02-2.40; RR = 1.10, 95% CI: 0.61-1.98, and RR = 1.18, 95% CI: 0.57-2.46, respectively. Conclusions: Occupational vibration was a risk factor for prevalent heart disease in Bulgaria. Noise was an alleged risk factor only among long-term workers and women.
