“…The age-strati ed prospective analysis ´showed exposed to heavy occupational lifting to increase risk for being a SBP case; 11% higher risk among workers aged ≥ 50 years and 5% higher risk among workers aged < 50 years (Table 2), similar to a previous study [7]. Older workers are likely to have been occupationally active throughout a longer time span than younger workers, and therefore the effect of the occupational exposures might be more pronounced.…”

“…This study contributes to the knowledge about the risk for hypertension from heavy occupational lifting by its aim to verify previous ndings [7] and to perform further analysis accounting for the moderating effects from LTPA. Thus, this study explored cross-sectional and prospective associations between heavy occupational lifting and hypertension in the Copenhagen General Population Study.…”

“…On the contrary, the adjusted prospective analysis indicated an 8% higher risk for being a SBP case by exposure to heavy occupational lifting (Table 2), while the linear regressions showed the greatest increase in SBP among those exposed to heavy occupational lifting (Table 4). Opposite to the BP effects from resistance training during LTPA [28,29], these results indicate heavy occupational lifting to have hazardous effects on BP, as previously indicated [7]. The background for increased risk for hypertension by exposure to heavy occupational lifting, may lie within the repeated acute peaks in BP during lifting tasks [5], occurring due to the occlusion of the vessels induced by static muscle activity leading to increases in total peripheral resistance [14].…”

“…The analysis strati ed by use of anti-hypertensives did not show results indicating users of anti-hypertensives to be especially vulnerable to rises in BP when exposed to heavy occupational lifting, as previously shown [7]. Yet, users of anti-hypertensives did not seem to have the bene cial lowering effects on BP by increasing level of LTPA, in the cross-sectional analysis (Table 5).…”

Background Prevalence of hypertension varies across occupations, maybe due to differences in exposure to occupational lifting. This study investigated associations between occupational lifting and hypertension, stratified by use of anti-hypertensives, leisure time physical activity (LTPA), occupational physical activity (OPA) and age.Methods Data from the Copenhagen General Population Study were included. The Copenhagen General Population Study was approved by the local ethical committee (H-KF-01-144/01), and all participation were conducted in accordance with the declaration of Helsinki. Multivariable logistic regression models, adjusted for sex, age, BMI, smoking, school education, mental stress and baseline blood pressure (BP), were applied to estimate: the (i) cross-sectional association (n=67,363) between occupational lifting and hypertension (using anti-hypertensives or BP ≥140/≥90 mmHg), (ii) prospective association (n=7,020) between occupational lifting and risk of an above median change in systolic BP (baseline to follow-up) and/or a shift from no use to use of anti-hypertensives, among the included population and stratified by use of anti-hypertensives, LTPA, OPA and age.Results Cross-sectionally, heavy occupational lifting lowered hypertension risk. Mean baseline BP, showed that the higher the level of LTPA the lower mean BP across all levels of OPA were, but only among those not using anti-hypertensives. The prospective analysis showed occupational lifting to increase the risk of hypertension, among workers aged ≥ 50 years, or reporting light to moderate LTPA. Conclusions This study finds positive associations between occupational lifting and risk for hypertension among workers aged ≥ 50 years. Further research on the association between occupational lifting and precursors of cardiovascular disease are needed before recommendations for occupational lifting and cardiovascular health can be established.
