If the waist-hip ratio of adult men exceeds 0.9, the risk of colorectal cancer will more than double, while if the daily leisure accumulation of working women is less than 1 hour, the risk of colorectal cancer will increase greatly.
Experts pointed out that colorectal cancer, also known as "cancer-rich", is more common in cities. If the waist-hip ratio of men is greater than 0.9, the higher the number, the greater the risk of illness.
Colorectal cancer is mainly caused by obesity. Both high-fat diet and low fiber intake may lead to colorectal cancer. It can be seen in the wards of colorectal cancer that almost all patients are obese, and most of them are severely obese. Especially people who are moderately obese, that is, people with bigger stomachs, are more likely to suffer from colorectal cancer. Therefore, it is best for obese men to measure waist circumference and hip circumference regularly.
Men over 45 years old (those with family genetic history should be over 35 years old) should not only pay attention to their waist and buttocks changes, but also have a fecal occult blood test and rectal examination every year. Li Ming said that colorectal cancer is very close to our life, especially in recent years, the number of patients has increased significantly, of which two-thirds are rectal cancer patients, and two-thirds of rectal cancer patients can be judged by rectal digital examination at an early stage.
2. Calculation method of waist-hip ratio
The method of measuring waist-hip ratio is very simple, that is, first measure the waist circumference and hip circumference, and then divide the waist circumference figure by hip circumference figure to get the ratio. If the female is below 0.85 and the male is not greater than 0.9, it means that it is within the healthy range. Waist-to-hip ratio of white men >: 1.0, and waist-to-hip ratio of women >; 0.85, for abdominal fat accumulation.
3. Waist-hip ratio is an index to predict obesity in early research.
The smaller the proportion, the healthier it is. This is a better way to predict whether a person is obese and at risk of heart disease, which is three times more accurate than the commonly used method of measuring body mass index (weight divided by the square of height). A large waist circumference indicates that there is fat in the abdomen, which is a signal of greater danger; Moreover, a person's hip circumference is large, which shows that his lower body is muscular and beneficial to people's health.
People with plenty of meat are relatively healthy and have slender limbs, but people with beer bellies are the most dangerous. Judging from the influence on blood vessels, blood lipids and arterial occlusion, the fat accumulated in the waist has a greater impact on health than the fat in the thighs and buttocks. Waist fat will destroy the insulin system, the metabolism of waist fat is quite fast, and it will also produce different hormones, leading to diseases such as diabetes, hypertension and hyperlipidemia. In addition, waist fat can also lead to liver hypertrophy, making it unable to function normally.
Waist-hip ratio is an index to judge abdominal obesity.
Standard value: male
Measurement method: After measuring the waist circumference, measure the hip circumference around the widest part of the hip, and divide the two to get the waist-hip ratio (waist-hip ratio example = waist circumference/hip circumference).
Waist-hip ratio is an important index to judge abdominal obesity. A study published in the New England Journal of Medicine involving more than 350,000 people in nine European countries found that the waist-hip ratio can measure a person's health standard more accurately than the body mass index. Studies have shown that every increase in waist-hip ratio of 0. 1 increases the probability of premature death of men by 34% and that of women by 23%.
