  1. *p < 0.2, ***p < 0.001
  2. Model 1 for age and sex, Model 2 for age, sex and BMI are adjusted
  3. h2: heritability estimates; c2: proportion of variance explained by common environments; SE: standard error, e2: proportion of variance explained by unique environments
  4. Model-2 results did not change after additional adjustment for BMI besides age and sex
