目的：开发并测试由访谈员管理的定量食物频率问卷 (FFQ)，以确定印度北部个体的营养摄入量。设计：根据研究区域的食物使用和市场调查开发了 92 项 FFQ。进行了一项验证研究，其中包括在一年内随机选择的 6 天进行 24 小时饮食回忆 (24HR)。实施了两次 FFQ，一年期开始和结束时各一次。使用相关性和回归分析并计算两种方法估计的营养摄入量之间的差异，对 FFQ 和 24HR 衍生的营养分数进行比较。地点：印度北部古吉拉特邦巴夫纳加尔区的农村。受试者：同意提供所有必要数据的 60 名个体。 结果：将 24HR 的营养分数与第一个 FFQ 的营养分数进行比较时，皮尔逊（参数）相关系数平均为 0.69，与第二个 FFQ 比较时，皮尔逊（参数）相关系数平均为 0.72（P
Objective: To develop and test a quantitative, interviewer-administered food frequency questionnaire (FFQ) to ascertain nutrient intakes of individuals in northern India.Design: A 92-item FFQ was developed based on food use and market surveys of the study area. A validation study was conducted consisting of 24-h diet recalls (24HR) administered on 6 randomly selected days over 1 year. Two FFQs were administered, one each at the beginning and end of the 1-year period. FFQ and 24HR-derived nutrient scores were compared using correlation and regression analyses and by computing differences between nutrient intakes estimated by the two methods.Setting: Rural villages in Bhavnagar District, Gujarat, North India. Subjects: 60 individuals who agreed to provide all necessary data.Results: Pearson (parametric) correlation coefficients averaged 0.69 in comparing nutrient scores derived from the 24HR with those from the first FFQ and 0.72 in comparing the second FFQ (P
