title: Influence of school, class, ethnicity, and gender on agreement of fourth graders to participate in a nutrition study.
abstract: This article describes the methods used to recruit fourth-grade children for a school-based study concerning the accuracy of their school breakfast and lunch recalls, and it reports the impact of school, class, ethnicity, and gender on agreement to participate. A total of 522 children (27% White Males [WM], 30% White Females [WF], 21% Black Males [BM], 22% Black Females [BF]) was available to recruit from 22 classes at six public schools in one district in a southeastern state during the 1999-2000 school year. Across classes, 45% to 95% of children agreed to participate (n = 376, 25% WM, 30% WF, 22% BM, 23% BF) with 72% overall. Logistic regression indicated class as a marginally significant predictor of participation (p < 0.04), but failed to indicate school, ethnicity, or gender as significant predictors. Other specific factors that may influence children's participation need to be investigated and results shared to help improve recruitment efforts for future school-based studies.
