1. Waist size:
The measurement of human body size uses a black scale, and the measurement scale starts from the place containing 2.3cm.
1. Pull out the tape measure and measure the parts to be measured.
2. Insert the magnetic head into the round hole on the tape body.
3. Press the button on the back of the ruler to make the ruler belt close to the measuring part.
4. Read some marked numbers. (The straight-line distance is measured with a red ruler).
Second, the use of body mass index ruler shell:
1. Turn the beige circle so that the value representing your weight on the outer ring corresponds to the value representing your height on the inner ring.
2. The data in the body mass index window below is your body mass index value.
Body Mass Index (BMI), that is, body mass index (BMI), is an index closely related to body fat, which mainly reflects overweight and obesity. Because the body mass index calculates the proportion of body fat, it is more accurate to measure the risk of heart disease, hypertension and other diseases because of overweight than to identify them simply by weight. The world standard of obesity is that the body mass index is in the normal range of 18.5 to 24.9, the body mass index greater than 25 is overweight, and the body mass index greater than 30 is obese. The Chinese Nutrition Association suggests that the healthy range of China residents' body mass index is 20 to 24, with a body mass index of 24 to 28 being overweight and a body mass index greater than 28 being obese.
Pull out the coiled soft ruler and measure a circle of 2 cm above the navel, that is, the waist circumference. Those whose waistline exceeds the red warning line should develop a scientific and healthy lifestyle, adjust their diet structure, strengthen physical exercise, and go to the hospital regularly to check their blood pressure, blood sugar and blood lipids. Those who exceed the red warning line and have high blood pressure should go to the hospital to check their blood pressure and blood sugar and receive medication guidance.
Obesity experts recently announced for the first time the appropriate waist circumference for adults in China: 85cm for men and 80cm for women. According to the survey, the risk of cardiovascular and cerebrovascular diseases will increase obviously in people with excessive waist circumference.
At the same time, experts suggest that China people's body mass index (BMI), that is, weight (kg) divided by the square of height (m), should be determined to be less than 24, and if it exceeds 24, it should be considered overweight, and the obesity BMI should be determined to be 28.
A large number of data prove that controlling the body mass index below 24 can prevent more than 38% hypertension and more than 33% diabetes, 8% and 29% coronary heart disease for men and women respectively, and 8% and 22% for obese people with a body mass index above 28 after stroke respectively. More than 90% of them were found to have abnormal risk factors. Controlling obesity can reduce the number of men and women by 65,438+respectively.
