目的食物频率问卷法(FFQ)问卷评估1~3岁幼儿膳食能量和营养素摄入量的准确性及重现性进行验证。方法采用分层整群随机抽样方式在中国北京分别选取2个社区卫生服务中心,随机抽取60名1~2岁幼儿和60名2~3岁幼儿,使用24h膳食回顾(24HDR)和FFQ收集其食物摄入资料,调查共两轮,间隔时间2个月,通过两轮24HDR和FFQ的均值间的比较进行FFQ准确性研究,首轮FFQ1结果与二轮FFQ2结果之间的比较进行FFQ重现性研究。结果由24 HDR计算得到的对象能量摄入为4.64kJ(1108kcal)/d,蛋白质、脂肪和碳水化合物摄入分别为41.4、44.7和146.9g/d。由FFQ得到的能量摄入量为4.76kJ(1138 kcal)/d,蛋白质、脂肪和碳水化合物摄入量分别为46.2、63.9和136 g/d,两种方法调查所得的膳食能量、蛋白质、碳水化合物及其供能比无显著性差异,FFQ显著高估膳食脂肪摄入量(高估42.9%)。FFQ得到的膳食维生素和矿物质的摄入量普遍高于24HDR,但低估了钠和硒的摄入量。由FFQ得到的能量和营养素摄入,只有能量、碳水化合物及其供能比、膳食纤维、维生素A、B2、钙和磷在能量调整后与24HDR呈显著正相关,相关系数在0.3~0.5之间。能量和营养素摄入在两轮FFQ间的Spearman相关系数在0.208(胡萝卜素)~0.593(脂肪)之间,且均呈显著性相关。结论 FFQ可以用于评估1~3岁幼儿膳食能量、碳水化物、膳食纤维、维生素A、维生素B2、钙和磷的摄入量,但FFQ不适于评估膳食脂肪、蛋白质及其他微量元素的摄入量。[营养学报,2014,36(1):45-48]
Objective The Food Frequency Questionnaire (FFQ) questionnaire was used to assess the accuracy and reproducibility of dietary energy and nutrient intakes of children aged 1-3 years. Methods Two stratified cluster random sampling methods were used to select two community health service centers in Beijing, China. Sixty children aged 1 ~ 2 and 60 children aged 2 ~ 3 were randomly selected and collected by 24h diet review (24HDR) and FFQ Food intake data were investigated for two rounds at intervals of two months. The FFQ accuracy study was conducted by comparing the mean of two rounds of 24HDR and FFQ, and the FFQ recurrence was compared by comparing the results of the first round of FFQ1 with the results of the second round of FFQ2 Sexual research. Results The energy intake of subjects calculated by 24 HDR was 4.64 kJ (1108 kcal) / d, and protein, fat and carbohydrate intake were 41.4, 44.7 and 146.9 g / d, respectively. Energy intake from FFQ was 4.76 kJ (1138 kcal) / d, protein, fat and carbohydrate intake were 46.2, 63.9 and 136 g / d, respectively. Dietary energy, protein, carbohydrate FFQ significantly overestimated dietary fat intake (overvalued 42.9%) with no significant difference in the compounds and their energy supply. FFQ intake of dietary vitamins and minerals are generally higher than 24HDR, but underestimated the intake of sodium and selenium. Energy and nutrient intakes obtained by FFQ were only energy, carbohydrate and their energy supply ratio. Dietary fiber, vitamin A, B2, calcium and phosphorus were positively correlated with 24HDR after energy adjustment with a correlation coefficient of 0.3-0.5 between. Spearman correlation coefficients of energy and nutrient intake between the two rounds of FFQ ranged from 0.208 (carotene) to 0.593 (fat) and were significantly correlated. Conclusion FFQ can be used to assess dietary intakes of carbohydrates, dietary fiber, vitamin A, vitamin B2, calcium and phosphorus in children aged 1-3 years, but FFQ is not suitable for assessing dietary intake of fat, protein and other micronutrients the amount.
