A cohort of 38-year-old men and women were studied for leisure time physical exercise in relation to low back pain (LBP), education, work, social class and smoking by a self-administered questionnaire. At the age of 14 years, the subjects had been interviewed by their school doctor regarding history of LBP and radiographs of the thoracic and lumbar spine were taken. The results show no positive correlation between radiographic changes and LBP in the adolescent period and decreased physical activity in adulthood. Physical activity for at least 3 h/week reduces the risk of LBP measured as lifetime, 1-year and point prevalence. Eighty-five percent of the subjects who reported taking physical exercise for at least 3 h/week had participated in sports activity almost constantly since their school days and these reported being in better condition than the rest of the cohort. Otherwise they did not have a healthier mode of life. No physical exercise during leisure time was associated with a short school education, unskilled work, unemployment and sickness, low social class, divorce, living in an apartment and smoking. Sixty percent had never or not for many years been interested in participating in sports. Badminton and tennis were the most common sports practised (36%), followed by gymnastics (32%), ball games-soccer and team handball-(25%), running (20%) and swimming (18%). Gymnastics and swimming seem to reduce LBP significantly. Our results show a falling interest in participating in sports activities over time, with 68% of the subjects being members of an athletic association previously, but only 29% currently. Women were more physically inactive during leisure time, probably because of their dual role. Logistic regression analysis indicates that physical activity is related to a long school education, high social class and regular sports activity over time.
通过一份自填式问卷，对一组38岁的男性和女性进行了研究，以了解休闲时间体育锻炼与腰痛（LBP）、教育程度、工作、社会阶层和吸烟之间的关系。在14岁时，学校医生对这些受试者进行了关于腰痛病史的访谈，并拍摄了胸腰椎的X光片。结果显示，青少年时期X光片变化与腰痛以及成年后身体活动减少之间没有正相关关系。每周至少进行3小时的体育活动可降低以终生患病率、1年患病率和点患病率衡量的腰痛风险。报告每周至少进行3小时体育锻炼的受试者中，85%自学生时代起就几乎一直参加体育活动，这些人报告的身体状况比该队列中的其他人更好。否则，他们并没有更健康的生活方式。休闲时间不进行体育锻炼与学校教育时间短、非技术工作、失业和疾病、社会阶层低、离婚、居住在公寓以及吸烟有关。60%的人从未或多年来一直对参加体育活动不感兴趣。羽毛球和网球是最常进行的运动（36%），其次是体操（32%）、球类运动——足球和团队手球——（25%）、跑步（20%）和游泳（18%）。体操和游泳似乎能显著降低腰痛。我们的结果显示，随着时间的推移，人们参与体育活动的兴趣在下降，之前有68%的受试者是体育协会的成员，但目前只有29%。女性在休闲时间身体活动较少，可能是因为她们的双重角色。逻辑回归分析表明，体育活动与长时间的学校教育、高社会阶层以及长期定期的体育活动有关。
