Most people think of high blood pressure, also known as hypertension, as a condition that affects older people. This may have been true in the past, but these days, high blood pressure affects people of all ages -- including young children.
Why is high blood pressure in children a growing problem? What can you do to protect your child from this threat? The first step is to learn all you can about high blood pressure in children, its causes, consequences, and treatment.
We know that starting as low as 115/75 mmHg, the risk of heart attack and stroke doubles for every 20-point jump in systolic blood pressure or every 10-point rise in diastolic blood pressure for adults aged 40-70.
Who Is at Risk for Prehypertension?
Nearly half of all adults older than age 18 have prehypertension or hypertension, as measured by average of two or more readings at two or more doctor's visits.
According to the American Heart Association, 59 million people in the U.S. have prehypertension.
People with prehypertension may have a greater risk for other cardiovascular disease (CVD) risk factors. These risk factors -- such as high cholesterol, obesity, and diabetes -- are seen more in people with prehypertension than in those with normal blood pressure.
Is Prehypertension a Result of Aging?
You may wonder if high blood pressure happens with aging, but experts say no.
Some populations across the globe have minimal rise in blood pressure with aging. In some parts of Mexico, the South Pacific, and other parts of the world, people have very low salt intake. In these areas, the age-related rise in blood pressure is small compared with the U.S.
Is There Treatment for Prehypertension?
Prehypertension is a warning sign. It means that you're at a greater risk of high blood pressure. Depending on your blood pressure and risk factors for heart disease, you may only need to make a few lifestyle adjustments. Here are some strategies to help you manage prehypertension:
Lose weight if you are overweight. Being overweight increases the risk of high blood pressure. However, losing weight can lower high blood pressure. Studies show that modest weight loss can prevent hypertension by 20% in overweight people with prehypertension.
Exercise regularly. Exercise helps you lose weight. Exercise also helps lower blood pressure.
Eat plenty of fruits, vegetables, whole grains, fish, and low-fat dairy. Studies show high blood pressure can be lowered and prevented with the DASH diet. This[TM1] diet is low in sodium and high in potassium, magnesium, calcium, protein, and fiber.
Cut back on dietary salt/sodium. A diet high in sodium (salt) can increase blood pressure. A low-sodium diet can lower high blood pressure -- or prevent it. Aim for less than 2,300 milligrams of sodium daily (about 1 teaspoon of table salt).
Eat foods low in saturated and trans fat and cholesterol. Diets high in saturated fat (meats and high-fat dairy), trans fat (some margarine, snack foods, and pastries) and cholesterol (organ meats, high-fat dairy, and egg yolks) may lead to obesity, heart disease, and cancer.
Eat a plant-based or vegetarian diet. Add high-protein soy foods to your diet. Increase servings of fruits and vegetables by adding one serving at a time. You can add a serving of fruit at lunchtime. Then add a serving of vegetables at dinner.
Drink only in moderation. Drinking excess alcohol can increase blood pressure. Limit drinking to no more than two drinks a day for men, and one drink a day for women.
