“…From a case-re fere nt study (12)(13)(14) of firs t-time prosth esis of the hip at four large hospitals in Stockholm , Swede n, the quantitative imp ortance of physical work load , sports, and overweight to the development of cox arthro sis has been studie d. Th e etiologic fractio n was calculated with the use of the fo llow ing operational entities for "physical work load": cum ulative number of hours exposed to dynamic work loads, cumulative number of hours working in a twisted locked pos ition, cu mulative number of ton s lifted , tota l number of heavy lifts , and cum ulative number of jumps . Th e cumulative numbers were collected up to the age of 49 yea rs, as we re the numbers of hou rs spe nt in spo rts act ivities.…”

“…The studies reported an increased risk especially for those with ≥10 years of employment as farmers or agricultural laborers (14,15) or >15 years of employment in jobs with heavy lifting (16) when compared to men who had undergone intravenous urography (15) or pyelography (16) or men with sedentary work (14). The risk of THR or being on a waiting list for THR has been examined in four casecontrol (17)(18)(19)(20) and one cohort study (21). Duration of employment in farm work was related to an increased risk in one of the case-control studies, which only included men (18).…”

Risk and rate advancement periods of total hip replacement due to primary osteoarthritis in relation to cumulative physical workload by Rubak TS, Svendsen SW, Søballe K, Frost P This is the first longitudinal study examining the risk and timing of total hip replacement (THR) due to primary osteoarthritis in relation to independently assessed lifelong cumulative physical workload at a population level. Among men, the most highly exposed group had an odds ratio of 1.3, and in this group, THR was performed 3.4 years earlier in life. Original article Scand J Work Environ Health. 2013;39(5):486-494. doi:10.5271/sjweh.3365 Risk and rate advancement periods of total hip replacement due to primary osteoarthritis in relation to cumulative physical workload Objectives This study aims to (i) evaluate relative risks, excess fraction of cases, and rate advancement periods for total hip replacement (THR) due to primary osteoarthritis in relation to lifelong cumulative physical workload and (ii) describe temporal trends in the proportion employed in the most highly exposed industries from 1986-2006. AffiliationMethods In a cohort study of the Danish working population, we assessed cumulative physical workload by combining year-by-year register information on employment industry with an industry exposure matrix that provided point scores (0-2) of physical workload. Cumulative physical workload was expressed as point-years corresponding to the pack-year concept of smoking. We retrieved register information on first-time THR during 1996-2006 and used a logistic regression technique to fit discrete time hazards models adjusting for age and other factors. We calculated excess fraction of cases and rate advancement periods.Results Total numbers of point-years ranged from 0-86. For men, an exposure-response relation was observed reaching an odds ratio of 1.33 [95% confidence interval (95% CI) 1.17-1.53] for the highest exposure category (35-86 point-years) compared to 0 point-years. The excess fraction of cases was 18%, and THR took place up to 3.4 years earlier with increasing exposure. For women, no exposure-response relation was found.Conclusions At the population level, cumulative physical workload increased the risk of THR among men, with surgery being performed slightly earlier in life. The proportion employed in the most highly exposed industries remained constant.
