Exploring the impact of the sodium-to-potassium ratio on longitudinal adolescent trajectories of blood pressure and cardiovascular risk

澳大利亚青少年的盐摄入量高，水果和蔬菜摄入量低。这种不良的饮食模式会提高尿中钠钾比（Na:K），而钠钾比是预测高血压和心脏病的指标。在青春期，青少年表现出血压的自然上升，这可能因尿钠钾过高而加剧。由于没有数据直接支持这一假设，本研究将探讨尿Na:K对澳大利亚青少年队列血压和心脏病风险的影响。

Australian teens have high salt and low fruit and vegetable intake. This poor dietary pattern can raise the sodium to potassium ratio (Na:K) in urine which is a marker that predicts high blood pressure (BP) and heart disease. At puberty, teens show a natural rise in BP which may be exacerbated by a high urinary Na:K. As no data directly support this hypothesis, this study will explore the impact the urinary Na:K has upon BP and heart disease risk in a cohort of Australian adolescents.
