Comparison of the Block Kid's Food Frequency Questionnaire with a 24Â h dietary recall methodology among Hmong-American children, 9-18 years of age

Abstract

Hmong are one of the immigrant Asian subgroups with increasing rates of obesity, type 2 diabetes and CVD. Despite their population growth in the USA and declining health status, no research has investigated the appropriateness of dietary assessment measures, including FFQ and 24Â h dietary recalls among Hmong. The present study compared the nutrient information obtained through a 24Â h dietary recall method with that collected using the Block Kid's Food Frequency Questionnaire (Block FFQ) among Hmong-American children (n 335) of 9-18 years of age. For this purpose, two 24Â h dietary recalls were collected during non-consecutive days and averaged for comparison. The Block FFQ was administered on the day of the second 24Â h recall and the two methodologies were also compared using t tests. Among all children, Block FFQ nutrient estimates for vitamin A, vitamin C and food group servings for vegetables and fruits were significantly higher than those assessed through the 24Â h dietary recalls (P
