According to the results of the health and nutrition survey in China in 20 12, the female obesity rate in China is about 16.4%, and according to the national nutrition and health monitoring data in 2020, the female obesity rate in China has risen to 26.8%. Obesity means that the weight exceeds the normal range, which is usually judged according to the body mass index (BMI). According to the definition of the World Health Organization, a body mass index greater than or equal to 25 is considered overweight, and a body mass index greater than or equal to 30 is considered obese.
The reasons for the increase of female obesity rate in China mainly include the following aspects: changes in lifestyle (such as changes in diet structure and sedentary lifestyle), changes in eating habits (such as increased intake of high-calorie, high-fat and high-sugar foods), lack of exercise and increased pressure. Therefore, compared with the obesity rate of 10%, the problem of female obesity in China is still serious. Relevant measures need to be taken, including healthy diet, moderate exercise and increased health education.
