Key result
Obesity was associated with a markedly increased risk of hypertension among adolescents (RR 8.7; 95% CI 8.1-9.5), with overweight also increasing risk (RR 2.8; 95% CI 2.6-3.2).

Supports screening obese adolescents for hypertension; leaves open whether weight loss reduces risk in this population.

Does overweight and obesity increase the risk of hypertension and prehypertension in Chinese adolescents?
Relative Risk: 8.7 (95% CI 8.1–9.5)
Overweight and obesity are strongly associated with a markedly increased risk of hypertension and prehypertension among Chinese adolescents.
Cao et al. (2012) conducted a cross-sectional in Hypertension and Obesity (n=88,974). Obesity vs. Normal weight adolescents was evaluated on Hypertension (HTN) (RR 8.7, 95% CI 8.1-9.5). Obesity was associated with a markedly increased risk of hypertension among adolescents (RR 8.7; 95% CI 8.1-9.5), with overweight also increasing risk (RR 2.8; 95% CI 2.6-3.2).
