作者为了解盐和水对血压的作用及高盐摄入与高血压病等的关系,选择美国密执安一个水中含盐量较高的县的郊区,在该区高盐湖泊附近居住的267户1003人中,无偏性地选择了97户295人进行了如下的调查:1.通过24小时饮食回顾和一周食品消耗的填写,详细了解其盐摄入情况并了解饮水的类型和检测其含盐度。2.进行病史了解及进行体格检查。3.收集一夜(9小时)后的晨尿连续三天(代表24小时)测其含盐量。结果:1.在饮用软化水(高Na~+,400mg/L左右)和非软化水(相对Na~+较低,200mg/L左右)的两群人中,盐指数(饮水而
In order to understand the effect of salt and water on blood pressure and the relationship between high salt intake and hypertension, we selected a suburb of a county in Michigan with a high salt content in the water and a population of 267 Among the 1003 households, 97 households with 295 persons were unbiased to conduct the following surveys: 1. Through a 24-hour diet review and a week-long food consumption, they learned more about their salt intake and the type of drinking water and tested them Salinity. 2. To understand the history and physical examination. 3. Collect the morning urine after a night (9 hours) for three consecutive days (representing 24 hours) to measure the salinity. In the two groups of people drinking demineralized water (high Na ~ 400mg / L or so) and non-demineralized water (relatively low Na ~ +, 200mg / L or so), the salt index
