- Coronary heart disease (CHD) is the number one killer of
American males and females. According to the American Heart
Association (AHA), approximately every 33 seconds an American
will suffer some type of coronary event and almost every minute,
someone will die from it.
- Heredity, although not a controllable risk factor, does play a role in heart disease
risk. In fact, children of parents who have heart disease are more likely to develop heart
disease later in life. Because individuals with a family history of heart disease are at a
greater risk, it is important to focus on controllable risk factors such as not smoking,
keeping cholesterol and blood pressure within a normal range, becoming physically active
and maintaining a healthy weight.
- Studies have shown that signs of heart disease begin developing in childhood.
- It is a well-established fact that high blood cholesterol levels play a role in the
development of coronary heart disease in adults. Because studies have shown that signs of
atherosclerosis begins in childhood, lowering levels of elevated blood cholesterol in
children and adolescents is beneficial.
- Children and adolescents who have high cholesterol levels are more likely than those in
the general population to become adults with high cholesterol levels.
- According to statistics from the American Heart Association, approximately 10 percent of
adolescents between the ages of 12 and 19 have "high" total cholesterol levels
(over 200 mg/dl). Among children and adolescents ages 4-19 years, average total
cholesterol and LDL (low density lipoproteins or "bad") cholesterol levels are
higher in females than in males. These averages also are higher in non-Hispanic black
children and adolescents when compared to non-Hispanic white and Mexican-American children
and adolescents.
- Research with families has found that simple dietary modifications can significantly
lower total and LDL cholesterol levels in parents and their children.
- According to the National Heart, Lung and Blood Institute (NHLBI), it is important to
establish healthy lifestyle habits early in life - such as healthy eating patterns - in
order to help keep the risk of heart disease low. The NHLBI has said, "Everyone older
than age 2 should care about cholesterol to reduce the risk of developing heart disease as
an adult. Children as well as adults can improve the health of their hearts by following a
low-saturated-fat and low-cholesterol diet, avoiding obesity, and being physically
active."
- Studies have found that 80 percent of adolescents between the ages of 13 and 18 exceeded
dietary recommendations for total and saturated fat. Another 49 percent exceeded
recommended intakes of dietary cholesterol; subsequently, these individuals were more
likely to show early signs of atherosclerosis.
- According to the American Heart Association, experts convened by the World Health
Organization (WHO) have said that obesity is rapidly increasing and is a threat to the
health of populations worldwide. These WHO experts also noted that obesity affects adults
and children alike.
- The well-known Bogalusa Heart Study found that children between the ages of 5 and 17 who
were overweight were 2.4 times more likely to have elevated total blood cholesterol levels
than children of normal weight. The study also indicated that of those children who were
overweight, more than half (58 percent) had at least one risk factor for heart disease.
- According to health officials, approximately 25 percent of children between the ages of
6 and 19 are overweight, which may place an alarming number of children and adolescents at
an increased risk for heart disease.
- Being physically inactive is as risky as having high blood cholesterol levels, high
blood pressure or cigarette smoking.
- Health experts recommend at least 30 minutes of physical activity each day to reduce the
risk of chronic disease, such as heart disease. Regular physical activity has dropped in
high school students from 42 percent in 1991 to 29 percent in 1999.
- The American Heart Association notes that physical inactivity is more prevalent among
young women than men. Blacks and Hispanics are less likely to be physically active than
their Caucasian counterparts.
