Key result
Higher dietary sodium intake was associated with a progressive increase in systolic blood pressure, with a mean difference of 2.6 mm Hg between the highest and lowest quartiles of intake among US children and adolescents.
Why the study?
Does higher dietary sodium intake increase blood pressure and the risk for pre-high blood pressure/high blood pressure in US children and adolescents?

May support sodium reduction counseling in US youth; leaves open causality and need for prospective trials.

Does higher dietary sodium intake increase blood pressure and the risk for pre-high blood pressure/high blood pressure in US children and adolescents?
Mean Difference: 2.6 (95% CI 1–4.2)
Absolute Event Rate: 108.8% vs 106.2%
p-value: p=0.010
Higher dietary sodium intake is positively associated with systolic blood pressure and the risk of pre-hypertension/hypertension in children and adolescents, with a synergistic, amplified effect observed in those who are overweight or obese.
Yang et al. (2012) conducted a cross-sectional in Blood pressure (n=6,235). Dietary sodium intake vs. Lowest quartile of sodium intake was evaluated on Mean adjusted systolic blood pressure (highest vs lowest sodium intake quartile) (MD 2.6, 95% CI 1.0-4.2, p=0.010). Higher dietary sodium intake was associated with a progressive increase in systolic blood pressure, with a mean difference of 2.6 mm Hg between the highest and lowest quartiles of intake among US children and adolescents.
