(HealthDay News) — About one in five children and adolescents had adverse lipid concentrations, and one in ten had borderline high or high blood pressure (BP) in 2011–2012, according to research published online January 19 in JAMA Pediatrics.

Brian K. Kit, MD, MPH, from the U.S. Public Health Service in Rockville, MD, and colleagues describe the prevalence of and trends in dyslipidemia and adverse BP in children and adolescents aged 8–17 years. Measured lipid concentrations were available for 1,482 children, and BP measurements were available for 1,665 children.

The researchers found that 20.2% of youth had an adverse concentration of total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), or non-HDL-C, and 11.0% had high or borderline BP in 2011–2012. Between 1999–2000 and 2011–2012, the prevalences of adverse concentrations of TC (P=0.006), HDL-C (P=0.003), and non-HDL-C (P<0.001) decreased significantly. High BP decreased from 1999–2000 to 2011–2012 (P=0.003). No significant change was seen in borderline high BP or either high or borderline high BP (P=0.90 and 0.26, respectively).

“The prevalence of dyslipidemia modestly decreased between 1999–2000 and 2011–2012, but either high or borderline high BP remained stable,” the authors write.
