Reproducibility and intermethod reliability of a calcium food frequency questionnaire for use in Hispanic, non-Hispanic Black, and non-Hispanic White youth.

ABSTRACT:

Background

A dietary assessment instrument designed for use in a nationally representative pediatric population was required to examine associations between calcium intake and bone mineral accrual in a large, multicenter study.

Objective

To determine the reproducibility and intermethod reliability of a youth calcium food frequency questionnaire (FFQ) in a multiracial/ethnic sample of children and adolescents.

Design

Reproducibility (n=69) and intermethod reliability (n=393) studies were conducted by administering repeat FFQs and three unannounced 24-hour dietary recalls to stratified random samples of individuals participating in the Bone Mineral Density in Childhood Study.

Participants/setting

Children and adolescents ages 5 to 21 years.
