1 WHO (1998) – global obesity defined as BMI ≥ 30 kg/m2; 2 NCEP-ATPIII (2002) – central obesity defined as WC > 102 cm for men and > 88 cm for women; 3 central obesity defined as WHtR ≥ 0.56 seconds VIEIRA (2009); 4 median: Ca:P ratio 0.57, Calcium 485.40 mg, Phosphorus 849.95 mg, Dairy products 0.90 servings, Whole milk 0.32 servings, Skim milk 0.00 servings, Yogurt 0.06 servings, Cheese 0.21 servings, All meats 1.49 servings, Red meat 0.83 servings, Poultry 0.39 servings, Fish 0.14 servings; 5 food consumption – servings (BRASIL.

6 crude values for calcium and phosphorus.

7 Sequential adjustment models by multiple regression - Model 1 – adjusted for age and gender; Model 2 – model 1 plus education level and per capita income; Model 3 - model 2 plus regular physical activity, dairy products and meats intake; Model 4 – model 3 plus calcium for the analysis of phosphorus and phosphorus for the analysis of calcium. After energy-adjusted of nutrients and after sequential adjustment for confounding factors by multiple regression were found positive relations significant between BMI and age, between WC and age and gender (male), and between WHtR and age, and negative between WHtR and education level.

Abbreviations: Ca:P ratio Calcium:phosphorus ratio, OR Odds ratio, CI Confidence interval, LL Lower limit, UL Upper limit, BMI Body mass index, WC Waist circumference, WHtR Waist-to-height ratio.
