Obesity

Obesity refers to a certain degree of obvious overweight and thick fat layer, which is a state caused by excessive accumulation of body fat, especially triglycerides.

Excessive food intake or changes in the body's metabolism leading to excessive accumulation of fat in the body, resulting in excessive weight gain and causing pathological, physiological changes or latency in the body.

Meaning: Obesity refers to a certain degree of obvious overweight and thick fat layer. It is a state caused by excessive accumulation of body fat, especially triglycerides. It does not refer to pure weight gain, but a state of excess accumulation of fat tissue in the body. Excessive food intake or changes in the body's metabolism leading to excessive accumulation of fat in the body, resulting in excessive weight gain and causing pathological, physiological changes or latency in the body.

The primary nature is related to the family, personal life habits, socio-economic development, cultural background and other environments, as well as poor dietary habits and insufficient exercise.

There are some differences in the amount of body fat between men and women, but it is roughly 20%. How much body fat is there, that is to say, body fat share = fat weight/body weight. Generally, the body fat of boys and girls during adolescence (12 years old) is roughly 20%. By the age of 18, body fat drops to 15% in men and rises to more than 20% in women. Both men and women over the age of 18 are on the rise. The normal body fat rate is 15%-20% for men and 20%-25% for women. If it increases from 20% to 25%-30%, then it is obese

Evaluation Standards

Obesity

Obesity=(actual weight-standard weight)÷standard weight×±100%

Obesity is within ±10%, which is called normal and moderate. Obesity over 10% is called overweight. Obesity is more than 20%-30%, which is called mild obesity. Obesity is more than 30%-50%, which is called moderate obesity. Obesity is more than 50%, and it is called severe obesity. Obesity is less than -10%, which is called lean. Obesity is less than -20% and is called weight loss.

Judgment of obesity

The commonly used body mass index (body mass index) is abbreviated as BMI, which is also translated as body mass index. It is an index that calculates a weight for height. The specific calculation method is the weight (kg, kg) divided by the square of height (m, m), that is, BMI = weight/height/height (kg/m2). Studies have shown that the body mass index of most individuals has a significant correlation with the percentage of body fat, which can better reflect the degree of obesity of the body.

Based on the analysis of body mass index to the degree of obesity, the world usually uses the body mass index threshold value established by the World Health Organization (WHO), that is, a body mass index of 25.0-29.9 is overweight, and 30 or more is obese. The China Office of the International Society of Life Sciences organized a "China Obesity Working Group" composed of multidisciplinary experts to assess the mass index (BMI), waist circumference, blood pressure, blood glucose, and blood lipids of 240,000 people in 21 provinces, cities, and regions in China. Relevant data is analyzed and the BMI standard for Chinese people is put forward accordingly. The BMI value "24" is the limit for Chinese adults to be overweight, and the BMI "28" is the limit for obesity; male waist circumference 85 cm, female waist circumference 80 cm The limit of abdominal fat
accumulation.
