Occupational Physical Loads and Hip Osteoarthritis: Final Performance Report

摘要

A case/control study was conducted to determine whether lifetime physical jobdemands are associated with a higher risk of hip osteoarthritis. Cases were individuals aged 50 to 72 who underwent hip replacement for primary osteoarthritis. There were 185 cases and 211 controls, matched for age, gender and geographic area. Subjects completed a three part questionnaire, concerning demographic and medical history, occupational exposure history, and recreational history. Job strength requirements were estimated for each job held. Years of medium, heavy or very heavy work were associated with the development of hip osteoarthritis in men and women, as were lifetime pounds lifted, standing and walking, and jumping from one level to another. The author concludes that cumulative occupational physical exposures were associated with the development of severe hip osteoarthritis.
