Percent agreement (%) and weighted kappa coefficients between parent and children BMI quintiles by dyad type and characteristics¹.

1For children, age- and sex-specific quintiles of BMI were used. For parents, sex-specific BMI quintiles were used. Weighted kappa values can be interpreted as follows: κ<0.20 = poor agreement, κ between 0.20–0.40 = fair agreement, κ between 0.40–0.60 = moderate agreement, κ between 0.60–0.80 = good agreement, and κ≥0.80 = very good agreement. 2The expected percent of agreement is 20%. 3SEM are reported in parentheses and were obtained through Fay's balanced repeated replication (BRR) method of estimation. 4Weighted kappa coefficients were calculated using the Cicchetti-Allison weight matrix (see text). All point estimates have taken MEPS’ sampling design into account. 5 NH, non-Hispanic; 5MVPA, moderate-to-vigorous physical activity. Source: Medical Expenditure Panel Survey, 2006–2007.
