What do you mean by BM 1, 18.5?

Body mass index = 18.5 indicates that the body mass index is at a normal level. BBMI means "body mass index" in Chinese, which is calculated by height and weight. Body mass index (BMI) is a world-recognized grading method to evaluate the degree of obesity and a standard to measure the degree of obesity and health status.

1, body mass index formula:

Body mass index (BMI) = weight (kg) ÷ height 2 (m)

For example, a person's height is 1.75m and his weight is 68kg, and his body mass index = 68/( 1.75 2) = 22.2.

Body mass index (BMI) is an index closely related to body fat, which takes into account two factors: weight and height. Body mass index is simple and practical, which can reflect the overweight and obesity of the whole body. It is more accurate to measure the risk of heart disease, hypertension and other diseases due to overweight than to identify them simply by weight.

Extended data:

Besides body mass index, waist circumference is a measure of obesity in China. Body mass index greater than or equal to 24 is overweight, and greater than or equal to 28 is obese; Male waist circumference is greater than or equal to 85 cm, and female waist circumference is greater than or equal to 80 cm.

Body mass index (BMI) is widely used to measure the degree of obesity in the world. Waist circumference is an important index to measure abdominal obesity, which reflects the degree of abdominal fat accumulation and is related to a series of metabolic abnormalities.

The summary analysis report of China Obesity Working Group shows that the increase of body mass index will also increase the incidence of coronary heart disease and stroke, and overweight and obesity are independent risk factors for coronary heart disease and stroke.

The relative risk of coronary heart disease, stroke and ischemic stroke increased by 65,438 05.4%, 6,654.38 0% and 65,438 08.8% respectively with the increase of BMI by 2. Once the body mass index reaches or exceeds 24, the probability of suffering from serious health-threatening diseases such as hypertension, diabetes, coronary heart disease and dyslipidemia will increase significantly.

Many studies show that Asians are already at high risk of cardiovascular diseases when their body mass index is low. That is to say, when their body mass index is lower than 25, the risk of hypertension in China begins to increase.
