天津市居民添加糖、食盐摄入量与血压值关系的研究

目的 分析了解天津市居民添加糖和食盐摄入情况，探讨其与高血压之间的关系，为高血压一级预防提供更可靠的依据。方法 根据2010-2012年中国居民营养与健康状况监测天津地区数据，采用连续3 d 24 h膳食回顾法、调味品称重法和食物频率法获得居民添加糖和食盐摄入量，现场测量血压获得血压值。结果 天津居民每标准人日添加糖和食盐平均摄入量分别为24.10 g和14.68 g。高血压人群收缩压和舒张压在不同添加糖摄入量下差异均有统计学意义（均有P<0.05），天津市居民血压值在不同食盐摄入量下差异均有统计学意义（均有P<0.05）。结论 天津市居民添加糖总体摄入水平虽尚在膳食推荐范围内，但高血压人群添加糖摄入量尚需注意，食盐总体摄入水平偏高，血压值随食盐摄入量增加而升高。

Association between added sugars and salt intake with blood pressure in Tianjin residents

Objective To analyze the intake of added sugars and salt and their association with hypertension in Tianjin residents,so as to provide a more reliable basis for primary prevention of hypertension.Methods Data was collected from 2010-2012 Chinese residents' nutrition and health condition surveillance.The added sugars and salt were record using successive 3 days 24 hours dietary retrospective method and seasoning weight method and food frequency method.Results The standard intake of added sugars and salt were 24.10g and 14.68g respectively among Tianjin residents per people per day.In hypertension population,there were significant differences in systolic blood pressure and diastolic blood pressure among all groups of added sugars (all P ＜0.05).In Tianjin residents,the differences in blood pressure among all groups of salt were significant (all P ＜ 0.05).Conclusions The added sugars intake was within the dietary guidelines recommended range.But in the hypertension people,the added sugars intake should be noticed.The salt level was higher than the guidelines recommended,the blood pressure rise with the increase of salt intake.
