The aim of this study was to design a food frequency questionnaire for pregnant women attending primary care under the Unified National Health System in Ribeirão Preto, São Paulo State, Brazil. A 24-hour food recall was obtained from 150 pregnant women, 50 in each trimester of pregnancy (age 18-35 years). A second food recall was obtained from 90 women, 30 in each trimester of pregnancy, from 7 to 15 days after the first dietary assessment. An 85-item questionnaire was developed with stepwise multiple linear regression models, based on the contribution of each food to inter-individual variation of energy and 28 target nutrients, which accounted for 74.2 to 98.8% of the selected nutrients. Portion sizes were determined according to percentiles 25, 50, 75, and 100 for each food item intake. To our knowledge, this is the first food frequency questionnaire designed for Brazilian pregnant women.
本研究的目的是为巴西圣保罗州里贝朗普雷图市统一国家卫生系统下接受初级保健的孕妇设计一份食物频率问卷。从150名孕妇中获取了24小时食物回顾信息，孕期每个阶段各50名（年龄18 - 35岁）。在首次饮食评估后7至15天，从90名女性中再次获取食物回顾信息，孕期每个阶段各30名。基于每种食物对个体间能量和28种目标营养素变异的贡献，利用逐步多元线性回归模型编制了一份包含85个条目的问卷，所选营养素的变异占比为74.2%至98.8%。根据每种食物摄入量的第25、50、75和100百分位数确定食物分量。据我们所知，这是为巴西孕妇设计的第一份食物频率问卷。
