目的:比较称重法、频率法与24 h尿钠法评估人群食盐摄入量的差异和相关性。方法于2011年6—9月在山东省采用多阶段分层随机抽样方法抽取18~69岁居民作为调查对象,共计2184名。分别采用24 h尿钠法、称重法和频率法进行食盐摄入量调查。同时记录3 d内家庭用餐人员(包括客人)的性别、年龄、就餐情况、劳动强度。采用问卷调查个人膳食习惯。结果24 h尿钠法、称重法和频率法调查的食盐摄入量分别为14.0、12.0和10.5 g/d。与24 h尿钠法相比,称重法和频率法每天食盐平均摄入量分别低2.0 g和3.4 g,分别低估了14.3%和24.3%;利用称重法和频率法低估和高估食盐摄入量的个体比例分别为42.4%(856/2020)、55.3%(1117/2020)和20.7%(418/2020)、16.3%(329/2020),即分别有36.9%(745/2020)和28.4%(574/2020)的个体其食盐摄入量在24 h尿钠法结果的±25%以内。称重法和频率法调查的食盐摄入量均与24 h尿钠法呈正相关(P<0.01),相关系数分别为0.13和0.07。采用三种方法调查的食盐摄入量均随着调查对象自我感觉咸淡口味的加重而逐渐增加。自认为口味偏淡、适中和偏咸的三组人群采用三种方法调查的平均食盐摄入量分别为:24 h尿钠法为13.6、13.6和14.7 g/d;称重法为11.0、12.0和12.7g/d;频率法为9.3、10.2和11.9 g/d,差异均有统计学意义(24 h尿钠法:F=0.47,P<0.05;称重法:F=5.83, P<0.05;频率法:F=12.53,P<0.01)。结论与24 h尿钠法相比,称重法和频率法均低估了实际食盐摄入量,通过调整低估率可以更准确地评估人群食盐摄入水平。
目的:比較稱重法、頻率法與24 h尿鈉法評估人群食鹽攝入量的差異和相關性。方法于2011年6—9月在山東省採用多階段分層隨機抽樣方法抽取18~69歲居民作為調查對象,共計2184名。分彆採用24 h尿鈉法、稱重法和頻率法進行食鹽攝入量調查。同時記錄3 d內傢庭用餐人員(包括客人)的性彆、年齡、就餐情況、勞動彊度。採用問捲調查箇人膳食習慣。結果24 h尿鈉法、稱重法和頻率法調查的食鹽攝入量分彆為14.0、12.0和10.5 g/d。與24 h尿鈉法相比,稱重法和頻率法每天食鹽平均攝入量分彆低2.0 g和3.4 g,分彆低估瞭14.3%和24.3%;利用稱重法和頻率法低估和高估食鹽攝入量的箇體比例分彆為42.4%(856/2020)、55.3%(1117/2020)和20.7%(418/2020)、16.3%(329/2020),即分彆有36.9%(745/2020)和28.4%(574/2020)的箇體其食鹽攝入量在24 h尿鈉法結果的±25%以內。稱重法和頻率法調查的食鹽攝入量均與24 h尿鈉法呈正相關(P<0.01),相關繫數分彆為0.13和0.07。採用三種方法調查的食鹽攝入量均隨著調查對象自我感覺鹹淡口味的加重而逐漸增加。自認為口味偏淡、適中和偏鹹的三組人群採用三種方法調查的平均食鹽攝入量分彆為:24 h尿鈉法為13.6、13.6和14.7 g/d;稱重法為11.0、12.0和12.7g/d;頻率法為9.3、10.2和11.9 g/d,差異均有統計學意義(24 h尿鈉法:F=0.47,P<0.05;稱重法:F=5.83, P<0.05;頻率法:F=12.53,P<0.01)。結論與24 h尿鈉法相比,稱重法和頻率法均低估瞭實際食鹽攝入量,通過調整低估率可以更準確地評估人群食鹽攝入水平。

Objective To compare the difference and correlation between dietary salt intakes assessed by 24 hours urinary Na method, food weighted record method and food frequency questionnaire method.Methods All 2 184 subjects aged 18 to 69 were selected by multi stage stratified cluster random sampling method in Shandong province in June to September, 2011.Dietary salt intakes were measured by 24 hours urinary Na method, food weighted record method and food frequency questionnaire method.The information on gender, age, dining locations and labour intensity of members dining at home for 3 days were recorded.And the dietary habits were surveyed by questionnaire.Results Salt intakes were 14.0, 12.0 and 10.5 g/d assessed by 24 hours urinary Na method, food weighted record method and food frequency questionnaire, respectively.Comparing with 24 hours urinary Na method, salt intakes assessed by food weighted record method and food frequency questionnaire method were 2.0 g (14.3%undervalued) and 3.4 g (24.3%undervalued) less, respectively.Comparing with 24 hours urinary Na method, the proportion of individuals with salt intake over-reported and under-reported were 42.4%(856/2 020) and 55.3%(1 117/2 020) by food weighted record method, and were 20.7%(418/2 020) and 16.3%(329/2 020) by food frequency questionnaire method, respectively;the proportion of individuals with salt intakes within ±25%of 24 hours urinary Na method were 36.9% ( 745/2 020 ) and 28.4% ( 574/2 020 ) , respectively.Salt intakes assessed by 24 hours urinary method correlated significantly with both salt intakes assessed by food weighted record method and food frequency questionnaire method;the correlation coefficients were 0.13 and 0.07, respectively.With the increasing of salt intakes by subjects′self-judgment, salt intakes were all rising significantly using three survey methods.Salt intakes of three group population of light, moderate and partial taste salty were 13.6,13.6 and 14.7 g/d by 24 hours urinary Na method (F=0.47,P<0.05);11.0,12.0 and 12.7 g/d by food weighted record method (F=5.83,P<0.05), and 9.3,10.2 and 11.9 g/d by food frequency questionnaire method (F=5.83,P<0.05), respectively.Conclusion Comparing with 24 hours urinary method, food weighted record method and food frequency questionnaire method would undervalue dietary salt intake.Salt intake status can be more accurately assessed by adjusting the underestimation rate.
