The association between chronic pain conditions and subclinical and clinical anxiety among community-dwelling older adults consulting in primary care.

Abstract

OBJECTIVE\nTo examine associations between chronic pain conditions, pain level, and subclinical/clinical anxiety in community-dwelling older adults.\n\n\nDESIGN\nCross-sectional associations were analyzed using multinomial logistic regression to compare the odds of having subclinical/clinical anxiety by painful condition and pain level, controlling for confounders.\n\n\nSETTING\nParticipants were recruited in primary care waiting rooms to take part in the first wave of the Étude sur la Santé des Aînés (ESA)-Services study.\n\n\nSUBJECTS\n1608 older adults aged 65+.\n\n\nMETHODS\nClinical anxiety was assessed using DSM-IV criteria. Subclinical anxiety was considered present when participants endorsed symptoms of anxiety but did not fulfill clinical diagnostic criteria for an anxiety disorder. Painful chronic conditions included arthritis, musculoskeletal conditions, gastrointestinal problems, and headaches/migraines. Presence of painful conditions was assessed using combined self-report and health administrative data sources. Pain level was self-reported on an ordinal scale. Physical comorbidities were identified from ICD-9/10 diagnostic codes and depression was evaluated based on the DSM-IV.\n\n\nRESULTS\nSixty-six percent of home-living older adults suffer from a chronic pain condition. Older adults with clinical anxiety are more likely to experience musculoskeletal pain, gastrointestinal problems, headaches/migraines, and higher pain levels compared to those with no anxiety. Also, those with ≥3 painful conditions are at greater risk for subclinical and clinical anxiety compared to those with no painful condition.\n\n\nCONCLUSIONS\nThese results emphasize the need for assessing anxiety symptoms in older adults with chronic pain conditions. Comprehensive management of comorbid chronic pain and psychopathology might help reduce the burden for patients and the healthcare system.
