	YES	NO
Reducing fat or calories	32.3 (28.7, 37.6)	29.6 (26.1, 34.7)	0.002
Increasing physical activity or exercise	32.4 (28.1, 37.2)	30.7 (26.9, 36.1)	0.200
Controlling or losing weight	32.3 (28.8, 37.3)	29.7 (26.0, 34.9)	< 0.001

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.
