在广西、山西农民和浙江渔民共705人中进行了连续三天的膳食调查,同时进行了病史询问和体格检查(包括血压测量)。结果发现,山西人群血压水平最高,其膳食结构的特点是高钠、低钙、低动物蛋白质;浙江人群血压水平最低,膳食结构的特点是高钠,高动物蛋白质摄入。多元回归分析结果显示:(1)根据钙的摄入量分为高钙组和低钙组,在低钙组中,个体的收缩压与钠/及钠/钾比值显著正相关;(2)个体动物蛋白质的摄入量,在调整了年龄、性别、体重指数、心率、饮酒精量、钠的摄入量及其它地区间整异等因素后,仍与血压呈显著性的负关联,提示动物蛋白质对血压具有保护作用。
In a total of 705 people in Guangxi, Shanxi farmers and Zhejiang fishermen for a total of 705 people for a three-day dietary survey, medical history and physical examination (including blood pressure measurement). The results showed that the highest level of blood pressure in Shanxi, the diet is characterized by high sodium, low calcium, low animal protein; Zhejiang blood pressure is the lowest level, the diet is characterized by high sodium, high animal protein intake. Multivariate regression analysis showed that: (1) According to calcium intake, high and low calcium groups were divided into two groups. In the low calcium group, individual systolic blood pressure was positively correlated with sodium / sodium / potassium ratio; (2) Individual animal protein intake, adjusted for age, gender, body mass index, heart rate, alcohol intake, sodium intake and other regional differences and other factors, and blood pressure was significantly negatively correlated, suggesting Animal protein has a protective effect on blood pressure.
