[Occupational activity and prevalence of osteomuscular pain among dentists in Belo Horizonte, Minas Gerais State, Brazil: a contribution to the debate on work-related musculoskeletal disorders].
The objective was to determine the prevalence of upper-limb and back pain among dentists (n = 358) and factors associated with these symptoms. Dentists were interviewed using a self-administered questionnaire containing data on sociodemographic, occupational, lifestyle, and psychosocial factors and presence, site, and characteristics of pain. Participation rate was 92.3%. 58% reported upper limb pain, with 22, 21, 20, and 17% for the arm, back, neck, and shoulder, respectively. 26% reported daily frequency and 40% classified pain as moderate or severe. In the multivariate analysis (multiple logistic regression), the factors associated with pain were: neck: anxiety/depression (OR = 2.3; CI95%: 1.2-4.5), compressor in the office (OR = 2.1; CI95%: 1.2-3.7), job satisfaction (OR = 0.3; CI95%: 0.1-0.9), and use of indirect vision (OR = 0.5; CI95%: 0.3-0.9); shoulder: income > 20 minimum wage (OR = 2.9; CI95%: 1.2-6.7), greater productivity (OR = 3.3; CI95%: 1.3-8.4), height > or = 160cm (OR = 0.3; CI95%: 0.2-0.7), and age 30-49 years (OR = 0.3; CI95%: 0.1-0.8); back: anxiety/depression (OR = 2.3; CI95%: 1.2-4.5), manual activity (OR = 0.4; CI95%: 0.2-0.9), and being married (OR = 0.5; CI95%: 0.3-0.9); arms: manual activity (OR = 1.8; CI95%: 1.0-3.2).
