Prevalence and characterization of chronic pain among the elderly living in the community

The purpose of this cross-sectional study was to determine the prevalence of chronic pain in elderly municipal employees (n = 451) in Londrina, Parana State, Brazil, and to characterize the pain in relation to: location, intensity, duration of episode, periodicity, and most frequent time of day. Data were collected using home interviews. Chronic pain was defined as lasting >= six months and the elderly were defined as >= 60 years of age. Overall prevalence of chronic pain was 51.44%, involving mostly the back (21.73%) and lower limbs (21.5%). Back pain was described as daily (31.63%), continuous, or lasting 1-6 hours (19.39%), mild (50%), and without a specific time of day (56.12%). Pain in the lower limbs was described as daily (42.27%), of variable duration (32.99%) or continuous (22.68%), mild (53.61%), and without a specific time of day (48.45%). The study showed a high prevalence of chronic pain in the elderly, with characteristics that can interfere in their quality of life, causing unnecessary suffering.
