限盐降压策略面临的挑战

详细叙述了限盐降压策略面临的三大挑战,是否要全民普遍限盐,是否血压降得越低越好,是否要吃得淡些更淡些。现有流行病学调查和临床试验结果表明,我国成人高血压盐敏感者约占相应总人口的三分之一强,约有7亿人不必严格限盐;降压治疗中可能存在J形曲线现象,血压降得过低,结局危险增大;每天摄入7~13 g食盐对健康较为有益,吃得＂淡些更淡些＂并不科学。

The Challenge of Limit Salt Buck Strategy

This paper describes detailly in three major challenges of the limit salt buck strategy,whether to limit salt for all the people,whether the bloodpressure lower is bether,whether to eat lightly. The epidemiological survey and clinical test results show that,China＇s adult in salt sensitive hypertension accounted for about 1 /3 of the total population,about 700000000 people do not have to limit salt strictly; there may be J shape curve phenomenon in antihypertensive treatment,blood pressure drop too low,result in increased risk; it＇s more useful for health to intake 7 ~ 13 grams of salt every day,eat＂more and more light＂is not science.
