Changes of height and weight after 50 years old: It is normal for the elderly to lose weight due to the decrease of some human tissue components, especially the decrease of intracellular fluid. However, some elderly people gain weight due to the decline of fat metabolism and excessive accumulation of fat in their bodies, so it is necessary to pay attention to prevent overweight. Due to the curvature of the spine and lower limbs, the height of the elderly has dropped slightly. According to a Japanese statistic, the average height of men dropped by 2.25% from 20 to 90 years old. along with

With the increase of age, the intervertebral disc of the spine shrinks and becomes thinner, and the spine gradually becomes shorter and curved, which gradually reduces the height of the elderly. Someone observed 534 elderly people for 8 years and found that the average height of male elderly people decreased by 3.77 cm, reaching 13.7 cm.

Generally speaking, the weight of the elderly tends to decrease gradually, but with the rapid development of social economy, the improvement of people's living conditions and the substantial improvement of living standards, the number of obese elderly people in China is also increasing gradually. The formula for calculating the standard weight of men recommended by the World Health Organization is (height cm-80) × 70%; Female (height cm-70) × 60%. But the standard adopted in China is body mass index = weight (kg) ÷ square kg/m 2 height (m). Normal weight: body mass index = 18-25 (China's physical fitness standard is 18-22 for women and 20-24 for men). The normal blood pressure range is 80-90/120-140mmhg. The correct way to measure blood pressure should be multiple times, using the same sphygmomanometer, the same person, the same person.
