[目的]以3天食物称重记录法为参照标准,对潮汕地区半定量食物频率调查表的有效性进行检验。[方法]在南澳城乡随机抽取若干被调查对象,首先用半定量食物频率调查表进行调查,1周后对同一对象用3d食物称重记录法进行重复调查,对调查结果进行相关性和一致性进行分析。[结果]100人完成调查.能量调整后被选定食物之间的Pearson’s相关系数(最小-中位数-最大)分别为0.31(蔬菜)-0.35-0.53(谷类),被选定营养素之间的Pearson’s相关系数(最小-中位数-最大)分别为0.12(视黄醇)-0.41-0.58(磷),多数结果之间显示出较好一致性,同时也出现部分一致性比较低的结果。[结论]潮汕地区半定量食物频率调查表有效性检验较高,可以用来评价潮汕地区被调查居民的膳食状况。
[Objective] To test the validity of semi-quantitative food frequency questionnaire in Chaoshan region by taking 3-day food weighing record as the reference standard. [Methods] A number of respondents were randomly selected from urban and rural areas of Nan’ao. The questionnaires were first surveyed by semi-quantitative food frequency questionnaire. One week later, the same subjects were repeatedly surveyed by 3-d food weighing record method. The correlation and consistency of survey results Analyze. [Results] 100 people completed the survey.The energy-adjusted Pearson’s correlation coefficients (minimum-median-maximum) between the selected foods were 0.31 (vegetables) -0.35-0.53 (cereals) Pearson’s correlation coefficient (min-median-max) was 0.12 (retinol) -0.41-0.58 (phosphorus), respectively, showing good agreement between most of the results and also lower partial consistency . [Conclusion] The test of validity of semi-quantitative food frequency questionnaire in Chaoshan area is high, which can be used to evaluate the dietary status of residents surveyed in Chaoshan area.
