  1. Cross-tabs for each medical advice and each behavior with quartiles of BMI were performed by complex analysis. Significance was based on the adjusted F and its degrees of freedom (adjusted for complex design). The adjusted F is a variant of the second-order Rao-Scott adjusted Chi-Square statistic.
