“…This finding is in accordance with the tendency already found in 1992 by Croft et al (16), who reported that squatting is protective for coxarthrosis. They calculated an odds ratio of 0.7 for coxarthrosis (95% CI 0.4-1.4) for people squatting more than 30 minutes a day.…”

“…The direction and strength of the association between BMI and hip pain is comparable to the associations found between BMI and coxarthrosis in previous casereferent studies [eg, those of Croft et al (16) and Vingård et al (13)]. In general, obesity needs to be conceptualized as both a risk factor and a consequence of coxarthrosis, the latter due to movement restrictions.…”

Objectives The aim of the study was to identify and quantify risk factors for hip pain. Methods A representative sample of 5001 Danish men and women aged 18-65 years in 1990 were interviewed about occupational exposures (response rate 90%); 5 years later they were reinterviewed about hip pain (response rate 86%). Logistic regression with forced entry of all the independent variables was used to estimate the odds ratios for the possible risk factors. The impact of the various predictors was assessed through the calculation of population etiologic fractions.Results A double risk of hip pain was found for the women as compared with the men [odds ratio (OR) 2.28, 95% confidence interval (95% CI) 1.68-3.09]. The risk increased with body mass index. Whole-body vibration (OR 1.86, 95% CI 1.09-2.71) and physically demanding work (OR 1.83, 95% CI 1.23-2.71) were strong predictors of hip pain, while a squatting work posture was protective (OR 0.64,. The impact of the statistically significant predictors (the etiologic fractions) was as follows: 0.49 for body mass index, 0.05 for whole body vibration, 0.10 for physically demanding work, and 0.32 for squatting (preventive).Conclusions Female gender, age, high body mass index, whole-body vibration, and physically demanding work are significant risk factors for hip pain.

“…Similarly, the prevalence of radiographic hip OA has been reported to be statistically significantly increased for farmers (12,46,47) and for those with jobs involving heavy manual labor (48,49) compared with population controls, ranging from factors of 3.2-10 to 2.0, respectively. Military service is somewhat comparable to farming and heavy manual labor in that the occupational demands often require regular heavy lifting, prolonged standing, and walking over rough terrain.…”

Objective. Although multiple studies have reported the prevalence of primary hip osteoarthritis (OA), little has been reported on incidence rates of hip OA. We sought to determine the incidence rate and demographic risk factors of hip OA in an ethnically diverse and physically active population of US military servicemembers. Methods. A query was performed using the US Defense Medical Epidemiology Database for the International Classification of Diseases, Ninth Revision, Clinical Modification code for hip OA (715.95). Multivariate Poisson regression analysis was used to estimate the rate of hip OA per 100,000 person-years, controlling for sex, race, age, rank, and service. Results. The overall unadjusted incidence rate of hip OA was 35 per 100,000 person-years. Women, compared with men, had a significantly increased adjusted incidence rate ratio for hip OA of 1.87 (95% confidence interval [95% CI] 1.73-2.01). The adjusted incidence rate ratio for black servicemembers when compared with white servicemembers was 1.32 (95% CI 1.23-1.41). The adjusted incidence rate ratio for the >40-year-old age group compared with the 20-year-old group was 22.21 (95% CI 17.54 -28.14). With junior officers as the referent category, junior enlisted, senior enlisted, and senior officers rank groups had a significantly increased adjusted incidence rate ratio for hip OA. With the Air Force as the referent category, each service had a significantly increased adjusted incidence rate ratio for hip OA. Conclusion. Female sex; black race; age >40 years; junior enlisted, senior enlisted, and senior officer rank groups; and military service in the Navy, Army, or Marines were all risk factors for hip OA.

“…Focusing on studies that included THR in their case definitions and applied some sort of cumulative exposure estimates, the body of literature is manageable. One cross-Rubak et al sectional study (14) and two case-control studies (15,16) examined the risk of radio-graphically diagnosed OA or a previous THR among men in relation to duration of employment in jobs with a high physical workload. 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).…”

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.
