The association between dietary phosphorus intake and the risk of hypertension remains uncertain. We aimed to investigate the relation of dietary phosphorus intake with new-onset hypertension among Chinese adults.
A total of 12,177 participants who were free of hypertension at baseline from the China Health and Nutrition Survey (CHNS) were included. Dietary intake was measured by 3 consecutive 24-hour dietary recalls combined with a household food inventory. New-onset hypertension was defined as systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg or diagnosed by a physician or under antihypertensive treatment during the follow-up.
During a median follow-up of 6.1 years, 4,269 participants developed new-onset hypertension. Overall, the association between dietary phosphorus intake and new-onset hypertension followed a U-shape (P for nonlinearity<.001). Consistently, when dietary phosphorus intake was assessed as quintiles, compared with those in the 3rd to 4th quintiles (912.0-<1089.5 mg/d), a significantly higher risk of new-onset hypertension was found in participants in the 1st to 2nd quintiles (<912.0 mg/d: HR, 1.23; 95% CI, 1.14-1.33), and the fifth quintile (≥1089.5 mg/d: HR, 1.21; 95% CI, 1.10-1.33).
There was a U-shaped association between dietary phosphorus intake and new-onset hypertension in general Chinese adults.
膳食磷摄入量与高血压风险之间的关联仍不确定。我们旨在研究中国成年人膳食磷摄入量与新发高血压之间的关系。
纳入了中国健康与营养调查（CHNS）中共有12177名基线时无高血压的参与者。通过连续3天的24小时膳食回顾结合家庭食物清单来测量膳食摄入量。新发高血压定义为收缩压≥140 mmHg或舒张压≥90 mmHg，或在随访期间由医生诊断或正在接受抗高血压治疗。
在中位随访6.1年期间，4269名参与者出现了新发高血压。总体而言，膳食磷摄入量与新发高血压之间的关联呈U形（非线性P<.001）。同样，当将膳食磷摄入量评估为五分位数时，与第3至第4五分位数（912.0-<1089.5 mg/d）的参与者相比，第1至第2五分位数（<912.0 mg/d：HR，1.23；95%CI，1.14-1.33）和第5五分位数（≥1089.5 mg/d：HR，1.21；95%CI，1.10-1.33）的参与者新发高血压风险显著更高。
一般中国成年人的膳食磷摄入量与新发高血压之间存在U形关联。
