- Low caloric intake is group of reference.

- All models are controlled for sex, age and BMI.

- High caloric intake; for males 1 to 3 years: > 1046 kcal/day; for males >3 years: >1742 kcal/day; for females 1 to 3 years: >992 kcal/day; for females > 3 years: > 1642 kcal/day. Cut points based on DRIs (EER).

* Difference between low and high caloric intake p < 0.05.

** Difference between low and high caloric intake p < 0.10 (marginal significance).
