New research suggests that there is a strong link between adolescent obesity and high blood pressure.
Researchers led by Yaron Arbel of Tel Aviv Medical Center found that body mass index (BMI) in healthy adolescents has a statistically association with both systolic blood pressures (SBP) and diastolic blood pressure (DBP), and highlights the significance of the global trend of rapidly increasing adolescent obesity.
"An important finding in our analysis is that BMI was positively associated with SBP and DBP in both the normal weight and overweight groups," Arbel said in a statement. "This highlights the importance of BMI as a marker for cardiovascular health in all body types."
For the study, researchers examined 715,000 Israeli adolescents, both male and female, between the ages of 16 and 20, who had received medical exams from 1998 to 2011.
They found a statistically significant link observed between BMI and blood pressure, both of which saw significant annual increases during the study. The percentage of overweight adolescents increased from 13.2 percent in 1998 to 21 percent in 2011, while the percentage of adolescents with high blood pressure (SBP > 130mmHg) rose from 7 to 28 percent in males and 2 to 12 percent in females.
The association of BMI to blood pressure was more pronounced in females than males. While the reason for this is not immediately clear, researchers hypothesized that it may be attributable to certain hormonal factors.
Arbel said the study highlights the need to address childhood obesity.
"Obese youth are more likely to have risk factors for cardiovascular disease, such as high cholesterol or high blood pressure," he said. "They are much more likely to be obese as adults and are consequently more at risk for adult health problems such as heart disease, type 2 diabetes, stroke, numerous types of cancer, and osteoarthritis."
The findings are detailed in the American Journal of Hypertension.
