摘要
目的 分析山东省居民食盐摄入量与血压水平的关系,为指导居民减少食盐摄入量以预防高血压提供依据.方法 于2011年6月在山东省采用多阶段分层随机抽样方法抽取2 184名18 ～ 69岁居民作为研究对象,测量其血压值并进行加权处理;通过连续3 d24h膳食回顾法和称重法测量其食盐摄入量,根据食盐摄入量的分布情况,以10、14和18 g/d为分界点进行分组.比较不同特征调查对象和以不同特征分层后各食盐摄入量组间收缩压、舒张压、高血压患病率的差异,并分析食盐摄入量与高血压患病率的关系.结果 2 184名调查对象中,实际完成并数据完整者2 133名,完成率为97.7％.经复杂加权后,调查对象收缩压和舒张压的均值（95％ CI值）分别为121.0（119.5～122.5）和78.5 （77.4 ～ 79.6） mmHg（1 mmHg=0.133 kPa）,均随食盐摄入量的增加而升高（F值分别为5.40、12.98,P值均＜0.05）,摄入量小于10g/d的调查对象血压最低,分别为119.6（116.9 ～122.4）和77.5（76.2 ～78.7） mmHg;18 g/d以上人群最高,分别为122.3（120.1～124.5）和79.6（78.2 ～80.9） mmHg.食盐摄入量与高血压患病率关系的分析结果显示,调整年龄、BMI等混杂因素后,在腰围正常的人群中,食盐摄入量在18 g/d以上的人群高血压患病率为小于10g/d人群的1.7（95％ CI：1.04 ～2.76）倍.结论 山东省居民高血压患病率较高,且血压水平与食盐摄入量有关.
Objective To study the relationship between salt consumption and blood pressure among residents in Shandong province,and to provide basic information for guiding people to prevent hypertension by reducing salt intake.Methods Using multi-stage stratified cluster random sampling method,2 184 residents aged 18 to 69 were selected as the research subjects,which were extracted randomly from 20 counties in Shandong province in June,2011.The blood pressure of the subjects were measured and weighted.Based on 72 h dietary recalls and weighing measurement,and according to the distribution of salt intake,the grouping cut-off points were 10,14 and 18 g.The difference of subjects with different characteristics and systolic blood pressure,diastolic blood pressure and prevalence of hypertension by grouping salt intake and other characteristics were analyzed,and the relationship between salt intake and prevalence of hypertension were analyzed.Results The total of 2 133 residents were involved finally,the completion rate was 97.7％.After the complex weighted,the systolic and diastolic blood pressure＇s means （95％ CI value） of the subjects were 121.0 （119.5-122.5） mmHg（1 mmHg =0.133 kPa） and 78.5 （77.4-79.6） mmHg respectively,which were all elevated with increasing of salt consumption.The blood pressure of the subjects with salt intake ＜ 10 g was the lowest,which were 119.6 （116.9-122.4） mmHg and 77.5 （76.2-78.7） mmHg respectively.The blood pressure of the subjects with salt intake ≥ 18 g was the highest,which were 122.3（120.1-124.5） mmHg and 79.6（78.2-80.9） mmHg respectively.The analysis results showed that,among residents with normal waistline,the prevalence of hypertension of people with salt intake ≥ 18 g was 1.70 （95 ％ CI：1.04-2.76） times compared to that of people who consumed less than 10 g salt per day.Conclusion The hypertension prevalence of Shandong province is quite high,and there is a relationship between salt consumption and blood pressure.
