British scientists warn people to pay attention to maintaining weight, because obesity increases the risk of chronic diseases such as diabetes, cardiovascular and cerebrovascular diseases, heart disease, stroke and other health problems. Among them, the latest experimental research shows that obesity can deprive people of 20 years of health and even shorten human life span by 1 to 8 years.
According to Steven Grover, the chief scientist of the trial and a professor at McGill University in Canada, they used a computer model to simulate the life of the obese and found that the degree of obesity really affects the life span. Compared with normal-weight people, the more obese people have a higher risk of chronic disease, the greater the chance of death, and the shorter the life expectancy. At the same time, the younger the age, the heavier the weight, the more significant the negative effects of obesity.
To complete the experiment, the scientists took samples from people between the ages of 20 and 79, and then retrieved certain physical data and medical diagnosis results from the British National Health and Nutrition Centre. After comprehensive data, it is found that the impact of obesity on human lifespan weakens with people s age. At the same time, gender and obesity are two other important factors that affect lifespan.
Scientists divided subjects into three categories according to their body mass index (BMI): general obese (index 25-29.9), moderately obese (index 30-35), and severely obese (index ≥35). The experimental results indicate that the life expectancy of general obese people will be shortened from 0 to 3 years; moderately obese people will be 1 to 6 years; and severely obese people will be 1 to 8 years. Among them, 20 to 29 years of age, regardless of gender, will be seriously impaired due to obesity, up to 19 years.
It is worth mentioning that according to a survey data released by the British Health and Social Care Information Centre (HSCIC), the obesity rate in the United Kingdom has increased tremendously in the past 20 years. As of 2012, more than 2/3 of the British The number of obese men and nearly 57% of obese women is staggering. Therefore, Grove warned everyone: The obese, especially young people, should change their eating habits and exercise more, so as to avoid the occurrence of chronic diseases, improve the quality of life, and extend their lifespan.
Hypertension 1. Hypertension is currently the most common disease. The prevalence rate in China is one in five people over the age of 15 and the total number of people in the country is 160 million. At present, the first factor leading to the high incidence of hypertension is obesity.
2. Waist circumference can well reflect local fat accumulation, and the ability to control abdominal obesity is important to prevent abnormal glucose metabolism. Men s waist circumference ≥85cm, women s ≥80cm, the risk of diabetes is quite high.
3. Obesity is closely related to coronary heart disease. The incidence of coronary heart disease is higher in obese people than in normal weight people, especially in the short-term obesity or severe obesity. Experts compared 35% overweight as the standard and found that obese and lean people in coronary heart disease accounted for 49.2% and 10.1%, respectively.
4. The prevalence of cancer in obese people is much higher than that of normal weight people, especially women. Women with obesity have a three-fold increased risk of breast, uterine, and cervical cancer, and a seven-fold increased risk of endometrial cancer. The risk of colon and prostate cancer among male obese patients is also significantly increased.
