title: [10-year epidemiological study on rheumatic diseases in Shantou area].
abstract: 22,049 adults were surveyed in a ten-year epidemiological study. The frequency of common rheumatic symptoms in Shantou population was much lower than that in northern China. The prevalence of ankylosing spondylitis, rheumatoid arthritis, osteoarthritis, osteoporosis and gout was 0.20%-0.32%, 0.20%-0.26%, 8.3%-10.8%, 12.4% and 0.15%-0.17% respectively. The frequency of HLA-B27 was 4.1% among general population and 90.6% in ankylosing spondylitis. The most commonly involved sites of osteoarthritis were lumbar spine, neck, and knee; but hands and hip were rarely involved. 85% subjects under investigation were found to be short of calcium intake. The differences between the north and the south of China in the prevalence of rheumatic symptoms may be related to the diversities in consciousness of seeking medical advice, reduction of bone content, climate and ergonomics.
