Key result
Obesity was significantly associated with elevated blood pressure in students (RR > 1.88, p < 0.0001), but 59% of the 26.4% of students with elevated blood pressure were not obese.
Why the study?
Most pediatric elevated blood pressure remains undiagnosed, and the American Academy of Pediatrics states there is limited evidence to support school-based blood pressure measurement.
Does school-based blood pressure screening identify elevated blood pressure in children regardless of weight status?
Population
4096 students ages 6 to 17 from Title 1 Miami-Dade Public Schools
Comparison
Blood pressure compared across BMI percentiles, ethnicity, and sex
Design
Cross-sectional study

School BP screening must extend beyond obese students; leaves open non-obesity contributors to pediatric hypertension.
Cross-Sectional (n=4,096)

Does school-based blood pressure screening identify elevated blood pressure in children regardless of weight status?
Relative Risk: 1.88
p-value: p=<0.0001
School-based blood pressure screening identifies a high prevalence of elevated BP in children, the majority of whom are not obese, supporting universal screening.
Silberstein et al. (2020) conducted a cross-sectional in Elevated blood pressure (n=4,096). Obesity vs. Non-obese was evaluated on Elevated blood pressure (RR > 1.88, p=<0.0001). Obesity was significantly associated with elevated blood pressure in students (RR > 1.88, p < 0.0001), but 59% of the 26.4% of students with elevated blood pressure were not obese.
