Epidemiology and risk factors for spine pain.

Low back and neck pain is a common problem and one of enormous social, psychologic, and economic burden. It is estimated that 15% to 20% of adults have back pain during a single year and 50% to 80% experience at least one episode of back pain during a lifetime. Low back pain afflicts all ages, from adolescents to the elderly, and is a major cause of disability in the adult working population. Risk factors for developing spine pain are multidimensional; physical attributes, socioeconomic status, general medical health and psychologic state, and occupational environmental factors all contribute to the risk for experiencing pain.
