Table 2 Environmental predictors of BMI, waist circumference, sum of skinfolds, %BF, VAT and SAAT in the combined LACHY and APEX studies

From: FTO variant rs9939609 is associated with body mass index and waist circumference, but not with energy intake or physical activity in European- and African-American youth

  1. Based on the model with age, gender, ethnicity, cohort and the interaction of gender and ethnicity. Negative and positive indicate the direction of relation between the predictor and dependent variables. P < 0.05 are indicated in bold. %V = explained variance.
  2. BMI = body mass index; %BF = percentage of body fat; VAT = visceral adipose tissue; SAAT = subcutaneous abdominal adipose tissue; VPA = vigorous physical activity; EI = energy intake; %FAT = percentage of energy from fat; %CARBO = percentage of energy from carbohydrates; %PRO= percentage of energy from protein.
