摘要

摘要: 目的探索社区健康人生理性功能衰老随年龄的变化趋势及其与人外周血白细胞端粒长度的关系，为科学评价衰老、延缓衰老提供依据或参考。方法采取分层随机抽样方法对南昌市20岁以上的健康人进行问卷调查，通过实时荧光定量PCR技术对部分样本外周血细胞端粒长度进行测量。结果现场实证研究共发放问卷1 000份，有效回收986份（98.60%），男女比例为0.97：1，分布均匀（t=1.319, P=0.995），年龄与衰老生理分值成高度正相关（r=0.892,P<0.001）。被测对象平均相对端粒长度为（1.057±0.031），老、中、青三个年龄段差异具有统计学意义（F=586.930，P<0.001），端粒长度与年龄（r=-0.814，P<0.001），生理性衰老分值（r=-0.682，P<0.001）均呈负相关。结论通过我国老年医学专家论证建立的生理性衰老指标体系，反映了生理衰老总分及方面得分随年龄增大而升高，并与端粒长度呈负相关的趋势。

Abstract: Objective To explore the change trends of telomere length in peripheral blood leukocyte with age and physiological aging in healthy community people and provide basic evidence and reference for aging evaluation. Methods Stratified random sampling was used to investigate healthy residents beyond 20 years old who lived in Nanchang. Quantitative real-time PCR technology was used to measure telomere length. Results A total of 1 000 questionnaires were distributed and 986 of them were valid after serious confirmation(98.60%). The ratio of male to female was 0.97:1. There was no significant difference in gender distribution (t=1.319, P=0.995). There was a positive correlation between aging scores and age(r=0.892, P<0.001).The result of telomere length showed that the average relative telomere length was(1.057±0.031).Telomere length of old, middle and young people were significantly different (F=586.930, P<0.001). Telomere length was negatively correlated with age(r=-0.814,P<0.001) and physiological aging scores(r=-0.682,P<0.001). Conclusions The established physiological aging index system which based on literature review and expert consultation showed that the score of physical aging and its three aspects increased with age and telomere length is negatively correlated with aging scores.
