First of a two-part series on cardiovascular prevention in children. Read part two.
As childhood obesity has increased over the past 30 years, so has pediatric hypertension, which now affects one in 20 children. However, 48 percent of children with high blood pressure (BP) are of normal weight; other risk factors include low birth weight, which has also increased in the past 30 years (more recently dipping slightly to about 8 percent of births).
While children with hypertension rarely develop diseases that adults do, such as myocardial infarction, heart failure and stroke, they are at risk for adult hypertension and early symptoms of heart disease. “Attacking pediatric hypertension is the next frontier in cardiovascular disease prevention,” says Justin Zachariah, MD, MPH, of the Department of Cardiology at Boston Children’s Hospital.
The Affordable Care Act’s mandate to identify elevated BP in children is expected to increase referrals for screening. But diagnosing pediatric hypertension through BP screening in the clinic can be problematic. In a recent study, Zachariah found that ambulatory BP monitoring (ABPM) with a take-home device is both effective and cost-effective—especially when done from the get-go. …
Despite recent national pediatric guidelines recommending identification and treatment of children with familial hypercholesterolemia, the use of lipid-lowering treatment has been flat over the past decade in real-world pediatric practice, finds a large multicenter study.
Justin Zachariah, MD, MPH, a pediatric cardiologist at Boston Children’s Hospital, presented the findings this week at the 2013 American Heart Association (AHA) Scientific Sessions. He believes they dispel some critiques of the recent guidelines, particularly concerns that more screening would result in overmedicating the pediatric population.
Extending beyond 2008 recommendations from the American Academy of Pediatrics, the 2011 National Heart, Lung and Blood Institute’s pediatric guidelines call for universal lipid screening and medical treatment for children at highest risk for early cardiovascular disease. One such high-risk condition is familial hypercholesterolemia, a genetic disorder characterized by high blood cholesterol levels, specifically very high levels of low-density lipoprotein (LDL, or “bad” cholesterol) and early coronary events. …

We all look at babies and fall in love with their chubby little legs and paunchy bellies. (When my younger son was a baby, a friend often jokingly threatened to “eat him like a marshmallow.”)
Cute as it is in babies, though, children can’t afford to have that cushioning as they get older. Obesity threatens the future health of a whole generation of children, putting them at risk for a host of long-term health problems like high blood pressure, type 2 diabetes (increasingly starting in childhood) and cardiovascular disease. This is on top of more immediate problems like sleep apnea, asthma, low self-esteem, depression, fatty liver disease (which can turn into cirrhosis) and joint pain. …
