Effects of physical fitness and blood properties of the elderly on their life expectancy and ADL (Results of a follow-up after 10-12 years)

通过调查老年人的身体健康状况、活到现在的状况以及死亡情况（死亡原因、不活动时间等），研究了1986年至1988年参加健康和运动能力调查（包括血液生化测试）的310名老年人的身体健康和血液特性对他们随后的预期寿命和ADL的影响。研究期为2年。1998年，对基线数据进行了回顾，并通过问卷（邮寄）询问了每个受试者从基线调查时间到现在的健康状况和生活状况。1999年，通过直接或电话对调查对象本人或其家属进行访谈，补充问卷所获得的数据。在老年受试者的肥胖程度、血脂水平和血压的基线数据中观察到区域差异。肥胖及其并发症如高脂血症和高血压经常被观察到，特别是在那些生活在城市地区的人（京都立医科大学公报，1998年）。此外，肥胖、高脂血症和高血压的发病率与就业率呈负相关，从事某些工作的人患这些疾病的几率较低（论文正在准备中）。在随访中确认存活的人群（164人）中，身体健康的基线水平更好，血压和血脂水平异常的基线频率也较低，低于已死亡的人群（50人）或生死状态未知的人群（93人）。

Effects of physical fitness and blood properties of the elderly on their subsequent life expectancy and ADL were studied in 310 elderly subjects who participated in the survey of fitness and exercise capacity (including blood biochemical tests) carried out between 1986 and 1988 by investigating the state of their physical fitness and living to the present day and the circumstances of death (causes of death, inactive period, etc.) in those who have died.The study period was 2 years. In 1998, the baseline data were reviewed, and an overview of the state of fitness and living of each subject from the time of the baseline investigation to the present day was inquired by a questionnaire (by mail). In 1999, the data obtained by the questionnaire were supplemented by interviewing the subjects themselves or their families directly or by telephone.Regional differences were observed in the baseline data concerning the degree of obesity, serum lipid levels, and blood pressure in the elderly subjects. Obesity and its complications such as hyperlipidemia and hypertension were observed frequently particularly in those living in urban areas (Bulletin of Kyoto Prefectural University of Medicine, 1998). Also, negative correlations were observed between the frequencies of obesity, hyperlipidemia, and hypertension and the employment rate, and the incidences of these conditions were lower in those engaged in some work (paper in preparation). The baseline level of physical fitness was better, and the baseline frequency of abnormal findings in the blood pressure and serum lipid levels was lower, in those confirmed to be alive at the follow-up (164 individuals) than in those who had died (50) or those whose life-or-death state was unknown such as those lost to the study (93).
