The prevalence of back and joint complaints and of rheumatoid arthritis (RA), chondrocalcinosis (CC) and osteoarthritis (OA) was studied in three representative population subsamples aged 70, 75 and 79 years. The prevalence of back pain was 38% and of joint complaints 40%, both significantly higher in females. The prevalence of RA was not significantly different between the age groups. Chondrocalcinosis increased with age in females. Radiographic and clinical OA of knees was less prevalent with increasing age. Symptoms of wrist and finger OA occurred in 1-4% of females but not males. Enlargement of DIP joints occurred in 50% of females and 25% males. Radiographic OA of first MCP joints was more prevalent with age in males but not females. Obesity correlated with radiographic OA of knees in females. Clinical and radiographic OA of fingers and knees did not correlate with previous strenuous occupations.
在三个具有代表性的70岁、75岁和79岁人群子样本中，研究了背部和关节疾病以及类风湿性关节炎（RA）、软骨钙质沉着症（CC）和骨关节炎（OA）的患病率。背痛患病率为38%，关节疾病患病率为40%，两者在女性中均显著更高。RA患病率在各年龄组之间无显著差异。软骨钙质沉着症在女性中随年龄增加而增多。膝关节的影像学和临床OA患病率随年龄增长而降低。手腕和手指OA症状在1%-4%的女性中出现，但男性未出现。远端指间关节（DIP）肿大在50%的女性和25%的男性中出现。第一掌指关节（MCP）的影像学OA在男性中随年龄增长更为普遍，但在女性中并非如此。肥胖与女性膝关节的影像学OA相关。手指和膝关节的临床和影像学OA与既往繁重职业无关。
