■在中国,随着预期寿命的增加和生育率的下降,老龄化问题日益突出,70岁以上老年人的身体问题是重点和难点问题。
■基于老龄化问题与老年人健康之间的互动逻辑,在研究中,对70岁以上的老年人进行了问卷调查和全国身体素质测试,分为不同年龄段(70-74岁,75-79岁,80-84岁,85岁及以上)和不同性别。有效样本有8400份,每组1,050人。单因素方差分析用于比较不同年龄群体之间的差异,并绘制折线图,讨论了我国70岁以上老年人各项体质指标的老化特征。
■(1)身体形态:男性腰围,男性腰围身高比和女性BMI随着年龄的增加呈逐渐下降的趋势;(2)生理机能:男性和女性肺活量随着年龄的增加呈下降的趋势,女性脉压呈逐渐上升趋势。(3)身体素质:男性和女性肌肉力量的指标,灵活性质量,有氧耐力和平衡能力随着年龄的增加呈下降趋势。
■生命能力,灵活性质量,肌肉力量,有氧耐力,平衡能力等等,随着年龄的增长显著下降。80岁是各项指标快速下滑的拐点。血压,无声脉冲,BMI,腰臀比,腰围身高比和其他指标没有随年龄的增长而定期变化。血压等指标,BMI,腰臀比和腰高比属于代谢性疾病和心脑血管疾病的高危范围。本研究对中国7个地理区域的70岁以上老年人进行体质测试,这是第一次针对老年人的全国性体能测试,这是国家体质监测系统的延伸和扩展,同时也表明“健康健身量表”所涉及的测试指标是简单可行的。这项研究增加了一系列70岁以上的测试数据,这是科学合理制定老年人体质评价标准的基础,对于完善国民体质数据库,掌握国民体质健康状况的动态变化具有重要意义,为老年人体育锻炼的科学指导提供数据支持。
UNASSIGNED: In China, with the increase of life expectancy and the decrease of fertility rate, the aging problem has become increasingly prominent, and the physical problems of the older people over 70 years are the key and difficult problems.
UNASSIGNED: Based on the interactive logic between the aging problem and the older people health, in the study, a questionnaire survey and a nationwide physical fitness test were carried out on the older people over 70, to divide into different age groups (70-74 years old, 75-79 years old, 80-84 years old, 85 years old and older) and different genders. There were 8,400 valid samples, and 1,050 persons in each group. One-way ANOVA was used to compare the differences among groups of different ages, and a broken line chart was drawn to discuss the aging characteristics of various physical indexes of the older people over 70 in China.
UNASSIGNED: (1) Body morphology: male waist circumference, male waist-to-height ratio and female BMI showed a gradual downward trend with the increase of age; (2) Physiological function: male and female vital capacity showed a decreasing trend with the increase of age, while female pulse pressure showed a gradual upward trend. (3) Physical quality: the indicators of male and female muscle strength, flexibility quality, aerobic endurance and balance showed a downward trend with the increase of age.
UNASSIGNED: Vital capacity, flexibility quality, muscle strength, aerobic endurance, balance ability and so on, decreased significantly with the growth of age. 80 years old is the inflection point of the rapid decline of various indicators. Blood pressure, silent pulse, BMI, waist-to-hip ratio, waist-to-height ratio and other indicators did not change regularly with age. Indicators such as blood pressure, BMI, waist-to-hip ratio and waist-to-height ratio were in the high-risk range of metabolic diseases and cardiovascular and cerebrovascular diseases. The study conducted physical fitness test on the older people over 70 years old in 7 geographical regions of China, which is the first nationwide physical fitness test for the older people, which is an extension and expansion of the national physical fitness monitoring system, and also shows that the test indicators involved in the \"Health fitness scale\" are simple and feasible. And the study added a series of test data over 70 years old, which is the basis for scientific and reasonable formulation of physical fitness evaluation standards for the older people, and is of great significance for improving the national physical fitness database and grasping the dynamic changes of national physical health status, and providing data support for scientific guidance of physical exercise for the older people.
