摘要
目的了解北京市居民食盐摄入水平。方法采用分阶段抽样法抽取城区、近郊区和远郊区各1个,进行6岁以上人群抽样调查。对调查对象进行问卷调查,并测定24小时尿钠含量。结果调查对象24小时尿钠含量的中位数为194.58mmol,相当于11.37克食盐。其中,城区165.79 mmol（9.69克）,近郊区200.43 mmol（11.71克）,远郊区226.80 mmol（13.25克）,远郊区人群最高（P〈0.01）;男性214.20mmol（12.52克）,女性180.06mmol（10.52克）,男性人群高于女性（P〈0.01）;6-18岁组130.34mmol（7.62克）,19-59岁组214.20mmol（12.52克）,60岁以上组187.45mmol（10.95克）,19-59岁劳动力人群最高（P〈0.01）。结论北京市居民食盐摄入量仍很高,急需加大干预力度,减少高盐饮食对健康的危害。
Objective To know the level of common salt of Beijing residents. Methods 873 persons aged over 6 were selected from 3 boroughs. A questionnaire study and 24 - hour urine sodium excretion assay were conducted. Results The median of twenty-four hours urinary natrium excretion was 194.58mmol, equal to 11.37g common salt. The salt level of the persons in town was 9.69g, the lever in suburb was 11.71g and the lever in exurb was the highest, 13.25g （P〈0.01）. The male＇s salt level was 12.52g, higher than the female＇s （10.52g） （P〈0.01）. The salt level of the persons aged 19 to 59 was the highest （10.95g） （P〈0.01）, the level of the aged 6 to 18 was 7.62g and the level of the aged upon 60 was 10.95g.
