  1. OSSLS2 Otago School Students Lifestyle Survey Two; Waist : Height = Waist Circumference (cm)-to-Height (cm) ratio.
  2. 1 GEE regression controlled for age (Model 1).
  3. 2 GEE regression controlled for age, sex, school decile, and ethnicity (Model 2).
  4. 3 GEE regression controlled for age, school decile, and ethnicity (Model 5).
  5. 4 Expected change in mean BMI z-score for every unit change in dietary pattern score.
  6. 5 Expected percentage change in geometric mean of body composition variable for every unit increase in dietary pattern score.
  7. 6 Significantly different from zero, P < 0.05.
  8. 7 Significant dieting status by dietary pattern interaction observed in Model 3 (See Figure 2 for model results that include a significant interaction term).
  9. 8 Significant sex by dietary pattern interaction observed in Model 4 (See Figure 1 for model results that include a significant interaction term).
