Reprodutibilidade de questões acerca da percepção do ambiente alimentar e acerca do consumo de frutas e hortaliças entre gestantes

Abstract

Objective: To verify the reproducibility of a questionnaire about perceived food environment and produce (fruits and non-starchy vegetables) intake by pregnant women. Methods: The study was conducted in 2010 and included 48 pregnant women followed by the public health care service of Ribeirão Preto, São Paulo. The questionnaire consists of 11 multiple-choice questions on the perceived food environment for produce intake. Reproducibility was determined by administering the questionnaire twice, 15 to 45 days apart. Result: agreement was measured by the kappa or weighted kappa coefficient. Results Strong agreement (Kappa from 0.6 to 0.79) occurred for: number of meals per day, habit of eating at work, distance from home to a produce retailer, and produce quality at the produce retailer. Moderate agreement (Kappa from 0.4 to 0.59) occurred for: habit of eating away from home, habit of eating at self-service or pay-by-weight restaurants, habit of eating at fast food restaurants, preferred food retailers (grocery, convenience store, bakery), reason for picking the produce retailer of choice, and produce variety. Conclusion: The questionnaire about perceived food environment and produce intake for pregnant women is consistent.
