Core tip: there are more than 200 million preschool children and school-age children in China, they are the flower and future of our country. Children's health should be concerned and valued by the whole society. Guizhou People's Hospital recently examined 9913 students from 7 primary school and middle schools in Guiyang, the capital city, and found that 465 students had high blood pressure and an incidence rate of 5.16%. Some data show that the proportion of children with hypertension is higher in the northern relatively rich areas. Why does adult disease focus on children?
Many parents don't know about the invasion of hypertension
Wen Wen, 10, is in the third grade of primary school this year. He likes singing and laughing and is very cute. Qianqian's mother only had this baby when she was 35 years old. She has taken care of her since she was born. What kind of nutrition to give her, what to eat, what to eat, what to buy for her, hoping her to grow up healthily. Unexpectedly, when the school carried out a health survey last semester, Qianqian was found to have child hypertension! Qianqian's mother was very puzzled: "my daughter is very normal at ordinary times, and she doesn't show the appearance of birth disease at all. How can she have children's hypertension?
Early childhood hypertension often has no obvious conscious symptoms. When the blood pressure is obviously increased, headache, dizziness, dizziness, nausea, and vomiting will appear. Because infants can't speak, they often show irritability, crying, too excited, irritable, and shrieking at night. Some patients did not gain weight, development stagnation. If the child's blood pressure is too high, there will be headache, dizziness, palpitation, and shortness of breath, blurred vision, convulsion, aphasia, hemiplegia, and other hypertensive crisis. When the brain, heart, kidney, and other organs damage seriously, it will lead to stroke, heart failure, uremia, and so on, endangering life.
Secondary hypertension in children in addition to the above performance, but also accompanied by primary symptoms, such as acute glomerulonephritis in children, in the blood pressure increased at the same time, there are fever, edema, hematuria, oliguria, proteinuria and so on. Pheochromocytoma in addition to increased blood pressure, there are palpitations, arrhythmias, sweating, cold hands and feet, and other symptoms. Renal artery stenosis, polycystic kidney, and so on can cause hypertension in infancy. Children often show fever, cough, and asthma, edema, pale, fatigue, etc., and eventually develop heart failure, which is often misdiagnosed as heart disease.
High salt diet is an important cause of hypertension in children
The researchers found that a high salt diet may raise blood pressure in children from the age of four. They believe that reducing their daily salt intake can reduce their risk of high blood pressure, stroke, and heart disease in the future.
The study, published in the Journal of hypertension, is based on data collected by the national diet and nutrition survey. An increase of 1 gram of salt per day will increase systolic blood pressure by 0.4 mm Hg, the report said.
The salt and Health Consensus action in the UK has strongly resisted claims from the food industry that the evidence for high salt intake is unclear. They believe that a lot of scientific research has linked high salt intake with the disease. If the food industry cooperates, it will be easy to reduce the current daily intake of 10-12 grams by 3 grams in the next 10 years.
The Food Standards Agency (FSA) is calling on parents to carefully check the salt content in the food labels they buy for their children and ensure that salt intake is below the daily recommended level. The Food Standards Agency recommends that younger children should eat less salt than older children. 3-year-old children 2 grams a day, 4-6-year-old children 3 grams a day, 7-10-year-old children 5 grams a day. Over 11 years old, 6 grams per day. Babies should not add salt to their food. The FSA advises: "these recommendations give maximum values, and it is better to use the lower than recommended values."
Children like fast food, coke, and instant noodles. However, foods like this, which are high in salt, fat, sugar, and caffeine, are all risk factors for high blood pressure in children. According to the survey by the salt and Health Consensus action organization, eating fast food can lead to more than twice the daily maximum salt intake recommended by experts. Some fast-food products have even the same salt content as seawater. The average salt intake per person was 5.2g for one serving of boneless chicken for four, and 12.3gg for each person for eating a four-person pizza set meal containing chicken wings, pizza, bread, and chips. The World Health Organization recommended that the daily salt intake of healthy adults should not exceed 6G. Meanwhile, it also recommended that the amount of salt for nonhypertensive patients with diabetes should not exceed 5g and that for hypertensive patients should not exceed 3GG.
