Decline in Ideal Heart Health Begins Early for Teen Girls

Heart health deteriorates as early as adolescence, with black girls experiencing greater rates of decline than white girls, according to preliminary research presented at the American Heart Association's Scientific Sessions 2019 in Philadelphia.
"Cardiovascular health declines in adolescent girls and some teens experience a greater loss of cardiovascular health than others. About 20% of the girls in this study entered young adulthood with low cardiovascular health (defined as less than half of the total possible ideal cardiovascular health score of seven key health factors," said lead study author Holly Gooding, M.D., an assistant professor of pediatrics at Emory University School of Medicine in Atlanta, Georgia. Gooding is a member of the American Heart Association's Cardiovascular Disease & Stroke in Women and Special Populations Committee.
Risk factors that contribute to heart disease can start as early as childhood and adolescence. These risk factors include obesity, tobacco, and alcohol use and lack of regular exercise, setting up youth for heart health problems later in life.
Obesity and physical inactivity are two of the biggest hurdles facing youth today, with nearly 24 million children ages 2 to 19 overweight or obese, and 15% of adolescents not getting enough exercise, a problem that is more common among girls than boys (19% versus 11%), according to 2015 data, the most recent year available.
Girls were also categorized into one of three categories -- ideal, intermediate or poor -- for six of the seven primary American Heart Association cardiovascular health metrics called Life's Simple 7: diet, exercise (at least 60 minutes per day for teens), abstaining from tobacco, a healthy body mass index, and healthy blood pressure and cholesterol levels. Researchers also noted when girls began menstruating and accounted for teen pregnancy and depression in the analysis.
Among the researchers' findings:
- Heart health declined between ages 9 and 19, particularly among black girls and girls from families with lower education and income levels.
- Menstruating before age 12 was associated with reduced heart health. Black girls began their periods on average one year earlier than white girls, with a greater percentage of black girls starting menstruation before age 12.
- Depression, which is known to affect diet, physical activity levels, and tobacco use, was also associated with reduced heart health.
- Teen pregnancy was linked to reduced heart health among teens.
- The study results suggest that pediatricians and primary care providers should pay closer attention to teens who may be at higher risk for reduced heart health, particularly girls from underserved communities.
