Cerebrovascular disease is a disease with multiple risk factors, some of which we cannot intervene, such as age, gender, race and family genetics, etc. These are called non-interventional risk factors. However, this does not mean that cerebrovascular disease cannot be prevented, because in addition to these non-interventional risk factors, there are more interventional risk factors, such as hypertension, heart disease, diabetes, dyslipidemia, obesity and poor lifestyle, oral contraceptives and hyperhomocysteinemia. These are well-recognized but often overlooked risk factors. It has been shown that a reduction in systolic blood pressure (SBP) by as little as 2 mmHg can reduce the incidence of hypertension by 17% and stroke by 14%. Cholesterol <200 mg/d L, BP ≤120/80 mm Hg (1 mm Hg=0.133 kPa), and non-smokers have 72%-85% fewer cardiovascular deaths and 40%-58% fewer total deaths than those with more than one risk factor, with an average life expectancy of 5.8-9.5 years. In short, a good lifestyle is important for the prevention of cerebrovascular diseases. The following is to change the bad lifestyle to pay attention to several aspects: 1, control weight medical commonly used body mass index to measure the degree of obesity: body mass index (BMI) = weight (kg) / height (m2). BMI in 18.5-22.9 for underweight, ≥ 23 for overweight, 23-24.9 for pre-obesity, 25-29.9 for Ⅰ degree obesity, ≥ 30 for Ⅱ obesity . Waist circumference and disease are proportional, obesity itself is a multifactorial chronic metabolic disease, often with type 2 diabetes, hypertension, dyslipidemia and other coexisting, medical called metabolic syndrome, and type 2 diabetes, dyslipidemia, hypertension, hyperuricemia, atherosclerosis and coronary heart disease have different degrees of connection. Therefore, overweight or obesity should reduce weight by reasonably controlling diet and reducing calorie intake; increasing exercise and increasing calorie consumption. 2.Rational control of diet In theory, every 6.8 kcal reduction will reduce body weight by 1 g. If the daily intake of 600-700 kcal is reduced, the weight can be reduced by 3 kg in one month. controlling diet is not equal to dieting. We should advocate healthy and scientific eating habits, reasonable nutrition and balanced diet. It is advisable to avoid additional meals and snacks between meals, and it is better to develop the habit of drinking soup before meals, although this can only achieve a temporary feeling of satiety, but it is positive for correcting "hunger" and "gobbling" behavior during meals. The rational diet should follow the principle of individualization, individual nutritional counseling and guidance, especially for bulimics to discover the reasons that trigger their eating, such as habitual (watching TV, etc.), social (eating candy, fruits, snacks, soft drinks and frequent banquets, etc.) or eating to get rid of depression, anxiety, etc., to help them adjust their lifestyles. 3, exercise therapy Exercise therapy does not mean that the greater the amount of exercise, the better the effect, people with cardiovascular disease should pay attention to gradual, consistent and measured, should not choose too strenuous exercise, generally light and moderate exercise is appropriate, such as walking, jogging, cycling, climbing stairs, dancing, playing tai chi, swimming, etc.. Sports training before the best exercise test, the intensity of training can also be heart rate as a standard, safe heart rate can be calculated by 170-age. Exercise intensity can be calculated by the maximum heart rate (maximum heart rate = 220 - age). To achieve effective weight loss, exercise therapy must be performed at least 3 times a week for at least 30 minutes. A study of 25714 male physical activity cases observed for 15 years proved that the total mortality rate of obese regular exercisers increased by only 10% in 15 years compared with normal weight regular exercisers; the total mortality rate of normal weight non-exercisers doubled; the total mortality rate of obese and non-exercisers increased by 3 times. In the cardiovascular and cerebrovascular disease, obese and often exercise people, compared with normal weight often exercise people suffering from cardiovascular and cerebrovascular disease risk only increased by 60%; obese and do not do exercise people, the risk of cardiovascular and cerebrovascular disease increased by 5 times; normal weight but do not do exercise people, the risk of cardiovascular and cerebrovascular disease death also increased by 3 times. This shows that life is exercise. The World Health Organization recommends a sodium intake of <6g per day, and the dietary sodium intake of our residents is generally high. Especially hypertensive patients consume too much salt is harmful. A recent report proved that the daily intake of more than 6g of salt and overweight people, the risk of stroke increased by 32%, stroke death rate increased by 89%, coronary heart disease death rate increased by 44%, cardiovascular death rate increased by 61%, the total death rate increased by 39%. The dietary structure should be based on cereal grains, depending on age, gender and physical activity intensity, the intake should be controlled at about 300-500 g/d, with coarse and fine grains, more coarse grains, mixed grains (including potatoes), etc. Eat more fruits and vegetables, consume 400-500 g/d of fresh vegetables, especially 100-200 g/d of green leafy vegetables and fruits to increase the intake of vitamin C, carotene, dietary fiber, potassium and other nutrients in the diet that are beneficial to cardiovascular and cerebrovascular health. A study of 84,521 women and 42,148 men demonstrated that this reduced the incidence of coronary heart disease. Beans and soy products provide high quality protein and calcium supplementation, with an average of 50-100 g per day. 250 g of milk or 1 bottle of yogurt per day can increase calcium intake. Meat and poultry can be consumed at 50-100 g per day, mainly lean meat and poultry meat, with little or no animal offal. Consume ≤1 egg per day. Fish should be consumed 1-2 times a week, 150-200 g each time, and vegetable oil should be used for cooking, 25 g/d. Sweets such as candy and cakes, which are likely to cause obesity, should be eaten sparingly or not at all. The energy of three meals should account for 30%, 40% and 30% of the total energy of breakfast, lunch and dinner respectively. Limit smoking and alcohol, smoking is harmful to health. The main harm to the cardiovascular and cerebrovascular is the temporary increase in blood pressure, but more importantly, smoking is an important risk factor for stroke, coronary heart disease, and myocardial infarction. Studies have shown that smoking increases the risk of ischemic cerebrovascular disease by a factor of 2, and is positively associated with the amount of smoking. Studies have shown that the risk of stroke is reduced within 2-4 years after stopping smoking. Therefore, smoking cessation may be one of the most effective lifestyle improvement measures to prevent cardiovascular disease. There is a dose-response relationship between the amount of alcohol consumed and blood pressure, with a gradual increase in blood pressure as the amount of alcohol consumed increases, and excessive alcohol consumption also increases the risk of stroke. Men should not consume >20-30g of alcohol per day (about 1 tael of white wine); women are more likely to absorb alcohol than men, so women should not consume >15g. Maintain psychological balance. A number of studies have pointed out that a good state of mind allows all systems of the body to function optimally, which is essential for reducing the incidence of cardiovascular disease. Many studies have shown that of all health care measures, maintaining mental balance is the most important, and its effect exceeds that of any other health care measures. Maintaining a peaceful and happy state of mind is sufficient to offset the negative effects of most unfavorable factors. In conclusion, strengthening publicity and education, changing unreasonable lifestyles, improving multiple risk factors and actively preventing them can ultimately reduce the occurrence of cerebrovascular diseases.
