“…A recent Danish study did not confirm an increased IHD risk for occupations involving lifting . However, this study was of lower methodological quality because it only controlled for age and socioeconomic status and did not use any individual‐level measures of lifting exposure but only used an occupational title.…”

Background: Research regarding the effects of occupational physical activity on health remains inconsistent. We analyzed the association of occupational physical activity with all-cause and cardiovascular disease (CVD) mortality. Methods: We analyzed two cohorts with baseline assessments from 1977 to 1993 ("National Research Program 1A" (NRP1A) and "MONItoring of trends and determinants in CArdiovascular disease" [MONICA]) and mortality follow-up until 2015 using adjusted Cox regression models. Results: We included 4396 NRP1A participants (137 793 person-years of follow-up, 1541 deaths) and 5780 MONICA participants (135 410 person-years, 1158 deaths).All-cause mortality was higher for men in the high compared with the low occupational physical activity category according to NRP1A (hazard ratio [HR] 1.25, 95% confidence intervals [CI] 1.05-1.50). CVD mortality was higher for men in the moderate compared with the low occupational physical activity category according to MONICA (HR, 1.41; 95% CI, 1.03-1.91). Results for women were not statistically significant. Conclusions:We observed higher total and CVD mortality risks in men with higher occupational physical activity but inconsistent results for women and across cohorts.

A meta-analysis suggests CVD risk reductions of 20%-30% for moderate (vs low) and of 30%-40% for vigorous (vs low) leisure-time physical activity. 3 Similarly, risk reductions of 35% in CVD mortality and of 33% in all-cause mortality in the most active compared with the least active participants were observed in another meta-analysis. 4 In general, earlier research regarding an association between physical activity and health focused on leisure-time physical activity. While the beneficial effects of this type of physical activity on the cardiovascular system are well documented, 3 the literature regarding occupational physical activity is rather inconsistent. 5 Some studies Am J Ind Med. 2019;62:559-567.wileyonlinelibrary.com/journal/ajim

“…Hypertension is a major preventable cardiovascular risk factor (7)(8)(9) and is estimated to cause 14% of all annual deaths globally (10). However, only few studies (4,5,11) have investigated the relation between heavy occupational lifting and hypertension, showing conflicting results. Thus, investigating these associations could reveal a potential for prevention of hypertension, especially among the 22% of the Danish workforce and 32% of European workers estimated to be exposed to heavy occupational lifting on a regular basis (12) (6 th survey in Eurofound).…”

Heavy lifting acutely increases blood pressure. However, only few inconclusive studies have investigated the prospective relation between heavy occupational lifting and hypertension. Our exploratory prospective analyses suggest that workers using anti-hypertensives or aged 50 years or older may be vulnerable to increases in blood pressure from heavy occupational lifting. However, further research is needed to confirm these associations.

“…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.

Ischaemic heart disease among workers in occupations associated with heavy lifting

Abstract: The results do not support the hypothesis that occupational heavy lifting is an important risk factor for IHD.
