Prevalence, determinants, and consequences of chronic neck pain in Finland.

Chronic neck pain is a relatively mild musculoskeletal condition, but common enough to be a possible public health problem. The distribution, determinants, and consequences of chronic neck pain have hitherto been described inadequately. In the Mini-Finland Health Survey, a representative population sample of 8,000 Finns aged greater than or equal to 30 years was invited to participate in a comprehensive health examination comprising an interview and a clinical examination; 90.2% complied. Predetermined criteria were used to diagnose major cardiovascular, musculoskeletal, respiratory, mental, and other disorders, regardless of other simultaneous disorders. Chronic neck syndrome was diagnosed in 9.5% of the men and 13.5% of the women. When adjusted for age and sex, the prevalence of the neck syndrome was associated with a history of injury to the back, neck, or shoulder and with mental and physical stress at work. Among those aged 30 to 64 years, overweight and parity were also significant determinants. Other musculoskeletal and mental disorders were associated with neck syndrome, and the association persisted after working conditions, injuries, overweight, and parity were adjusted for. There was some independent association between neck syndrome and disabilities, use of physician services, and use of pain killers.
