[BDSP. Notice produite par INIST-CNRS OCcUR0xm. Diffusion soumise à autorisation]. Epicondylitis is a common disorder of the arm, yet the role of individual-and work-related factors has not been addressed in a population study. The aims of this study were to estimate the prevalence of lateral and medial epicondylitis and to investigate their risk factors. The target population of this study comprised a representative sample of people aged 30-64 years residing in Finland during 2000-2001. Of the 5,871 subjects, 4,783 (81.5%) were included in this study. The prevalence of definite lateral epicondylitis was 1.3%, and that of medial epicondylitis was 0.4%. The prevalence did not differ between men and women and was highest in subjects aged 45-54 years. Current smoking (adjusted odds ratio (OR)=3.4,95% confidence interval (Cl) : 1.4,8.3) and former smoking (OR=3.0,95% Cl : 1.3,6.6) were associated with definite lateral epicondylitis. An interaction (p=0.002) was found between repetitive movements of the arms and forceful activities for the risk of possible or definite lateral epicondylitis (for both repetitive and forceful activities vs. no such activity : OR=5.6,95% Cl : 1.9,16.5). Smoking, obesity, repetitive movements, and forceful activities independently of each other showed significant associations with medial epicondylitis. Epicondylitis is relatively common among working-age individuals in the general population. Physical load factors, smoking, and obesity are strong determinants of epicondylitis.
