Medical and Exercise Consultation Use for Low Back and Knee Pain Among Cardiovascular Mass Screening Population: A Cross-sectional Study

Low back and knee pain, as major symptoms and early signs of osteoarthritis, have restricted healthy life expectancy, and numerous guidelines have recommended therapeutic exercise as the first-line treatment for chronic pain. Proportions of medical and exercise consultation use for those pain have been unclear, and these may change in the future. We performed a cross-sectional study of 2,954 persons aged over 30 years in 2017 as a part of the Circulatory Risk in Communities Study. A generalized linear model with logit link and 11-year age-group moving averages were used to estimate sex- and age-specific average proportions of lifetime pain, chronic pain, and dysfunctional chronic pain of the low back and knee, and history of medical and exercise consultation use. The medical consultation use increased in the order of lifetime pain, chronic pain, and dysfunctional chronic pain, reaching 69.1 % [65.2, 72.8] in women and 74.9 % [70.3, 79.0] in men for chronic low back pain, and 70.3 % [66.1, 74.2] in women and 55.6 % [49.3, 61.7] in men for chronic knee pain. On the other hand, the exercise consultation use accounted for 36.5 % [32.6, 40.6] in women and 28.8 % [24.4, 33.5] in men for chronic low back pain, and 40.8 % [36.5, 45.2] in women and 20.6 % [16.0, 26.0] in men for chronic knee pain. This survey revealed the differences in the multilayer proportions of medical and exercise consultation use for low back and knee pain in the cardiovascular mass screening, suggesting exercise consultation was less often provided compared to medical consultation.
