Hispanic and White Adolescents More Likely Than Black and Asian Peers to Develop Hypertension with Obesity

4/10/2017
Race and ethnicity may tip the scale on how often adolescents with obesity also develop hypertension, according to a new study in the May 2017 Pediatrics. For the study, “Race and Obesity in Adolescent Hypertension” (published online Monday, April 10), researchers measured the blood pressure, along with height and weight for body-mass index (BMI), of more than 21,000 adolescents at 27 Houston area schools between 2000 to 2015. Readings were taken on three separate occasions to identify students, who ranged in age from 10 to 19, with sustained hypertension. Overall, about one-third of the adolescents were overweight or obese, which aligned with national estimates, and students in these categories had the top overall rates of hypertension.  Researchers noted a disproportionate rise in the prevalence of hypertension among obese Hispanic and white students (7.7 percent and 7.4 percent, respectively), however. Conversely, while blacks had the highest prevalence of hypertension among normal weight (2 percent) and overweight (2.8 percent) subjects, they had the lowest rate of hypertension among obese subjects (4.5 percent). The Asian cohort had lower hypertension rates across all BMI groups. As early-onset cardiovascular disease becomes a growing problem among U.S. youth, the study’s authors said their findings support the need for a variable approach to BMI interpretation in a racially and ethnically diverse population.
