EPIDEMIOLOGICAL STUDY ON THE EFFECTS OF PHYSICAL FITNESS ON MORTALITY AMONG MEDDLE-AND OLD-AGED PEOPLE

进行了一项随访研究，以明确体力水平与各种原因、癌症和心血管疾病死亡风险之间的关系。1983年至1987年期间，在四个健康促进中心对40岁或40岁以上的4,771人（2,323名男性和2,448名女性）进行了检查。到1996年，对4 692人（2 288名男子和2 404名妇女）进行了问卷调查。随访率为98.3%。在此期间，据报有219人死亡。在基线时，进行五项体力测试（侧步、站立躯干屈曲、仰卧起坐、握力和垂直跳跃）。被试被问及吸烟状况（当前吸烟者、不吸烟者和戒烟者）。侧步（RR=1.46）和垂直跳跃（RR=1.60）值较低的人死于各种原因的风险较高。垂直跳值较低的人（RR=3.81）死于心血管疾病的风险也较高。总体健康评分较低（RR=2.76）的人死于心血管疾病的风险也较高。在调整吸烟状况后，结果与前相同。由此得出结论，低水平的体力可能与随后的健康结果显著相关。

A follow-up study was conducted to clarily the relationship between physical-strength level and risk of death from all causes, cancer, and cardiovascular disease. A total of 4,771 persons (2,323 men and 2,448 women) who were 40 years old or older were examined at four health-promotion centers between 1983 and 1987. By 1996,4,692 persons (2,288 men and 2,404 women) had been contasted by questionnaire. The follow-up rate was 98.3%.During this period, 219 deaths were reported. At baseline, five physical-strength tests (side step, standing trunk flexion, sit-ups, grip strength, and vertical jump)were performed. The examioniees were questioned about smoking status (current smoker, nonsmoker, and ex-smoker).People with lower values for side step (RR=1.46) and vertical jump (RR=1.60) had an excess risk of death from all causes. People with lower values for vertical jump (RR=3.81) had an excess risk of death also from cardiovascular disease. People with low values for total fitness score (RR=2.76) also had an excess risk of death from cardiovascular disease. After adjustment for smoking status, the results showed same tendency as before. It is concluded that a low level of physical strength might be significantly correlated with subsequent health outcomes.
