Background: Children in industrialized and developing countries have a higher tendency to present earlier signs of puberty. One hypothesis includes the hormonal effects of phytoestrogens found in soy products.
Objective: to examine the association between consumption of soy-based food in early infancy and childhood and the incidence of early or precocious puberty and overweight in school-aged children.
Methods: the study population for this case control study is randomized from a prospectively followed cohort of all babies born at Assaf Haroffeh medical center and followed for milk allergy signs and food intake until the age of 3 years (A nested cohort). It is divided to those who were allergic to milk, and thus consumed only soy based formula and food during infancy and childhood (soy group) and a randomized control group who consumed non-soy based intake. For both groups data are available of food habits during infancy and collected from 3 days food diaries during the current study. Physical examination, including weight , height, blood pressure and Tanner Pubertal Staging will performed annually.

Soy based formula
"soy group" will include children from the children who had milk allergy, and consumed a soy-based substitute formula for longer than three months and agreed to participate in this study.
Behavioral: soy based formula at infancy
The intervention is only past history of soy consumption
The control group will included children (at a rate of 2:1) who will be assigned randomly from the healthy population at the initial cohort, and who will agree to participate.
- Age of adrenarche signs [ Time Frame: 5 years ]Age of adrenarche signs will be compared between soy and control groups
- Age of gonadarche signs [ Time Frame: 5 years ]Age of gonadarche signs will be compared between soy and control groups
- comparison of rate of Overweight and obesity [ Time Frame: 5 years ]BMI-SDS will be compared between groups
