摘要

背景和目的:孕期营养对母亲和胎儿的健康起着重要作用,并进一步影响儿童的发育。铁是孕期所需的最重要的微量营养素之一。目前还没有经过验证的食物频率问卷(FFQ)来评估孕妇的铁摄入量。研究方法根据研究地区的饮食习惯和富含铁的食物,并参考标准文献,编制了食物频率问卷。FFQ 分为以下几类:谷物及谷物制品、豆类及豆制品、绿叶蔬菜、根茎及其他蔬菜、坚果及种子、水果、非蔬菜食品和奶及奶制品。由学科专家进行内容效度验证。为了进行结构效度验证,25 名初级保健中心和 25 名三级保健医院的孕妇接受了本 FFQ 和 24 小时饮食回忆法的访谈。使用 Wilcoxon 符号秩检验对两种记录的结果进行分析。问卷的内部信度(Cronbach's alpha)和结构效度(Pearson correlation)得到了确定。结果问卷的总体内部信度为 0.804,显示出良好的信度和令人满意的结构效度。FFQ法得出的膳食铁摄入量中位数为7.67毫克/天,24小时膳食回忆法得出的膳食铁摄入量中位数为15.70毫克/天。结论 本研究设计的 FFQ 是评估孕妇膳食铁摄入量的可靠、有效的工具。

“Food frequency questionnaire for dietary intake of iron in pregnancy- A validation study”

Background and objective

Nutrition in pregnancy plays an important role for wellbeing of mother and fetus, later it further influences the development of child. Iron is one among the most important micronutrients required in pregnancy. There is no validated Food frequency questionnaire (FFQ) to assess iron intake in pregnant women. This initiated the process to develop and validate a FFQ to assess dietary intake of Iron in Pregnant women.

Methodology

Based on the food habits in study region and foods rich in iron, in reference to the standard literature, the FFQ was prepared. FFQ was designed in the following categories-cereal grains and products, pulses & legumes, green leafy vegetables, roots-tuber & other vegetables, nuts & seeds, Fruits, non-veg foods and milk & milk products. Content validity carried out by subject experts. To perform construct validity, 25 Primary health centre and 25 Tertiary care hospital pregnant women were interviewed using this FFQ and 24 h diet recall method. The results of both records were analyzed using Wilcoxon signed rank test. Internal reliability (Cronbach's alpha) and construct validity (Pearson correlation) of the questionnaire were determined.

Results

Overall internal reliability of questionnaire is 0.804, indicating good reliability and showing satisfactory construct validity. Median dietary iron intake from FFQ method was 7.67 mg/day and 24 h dietary recall method was 15.70 mg/day. There was a significant difference between both method in assessing dietary iron intake.

Conclusion

The FFQ designed in this study is reliable and valid tool to assess dietary iron intake among pregnant women.
