A young girl's relationship with her family, especially with her father, may influence at What age she enters puberty, say researchers at Vanderbilt University, Nashville, Tenn. The study examined 173 girls and their families from Nashville and Knoxville, Tenn., and Bloomington, Ind., from the time the girls were in pre-kindergarten until they were in the seventh grade.

Those who had close, positive relationships with their parents during the first five years of life tended to experience relatively late puberty, compared to girls who had more distant relationships. More specifically, it was found that the quality of fathers' involvement with daughters was the most important feature of the early family environment in relation to the timing of the daughters' puberty.

Girls who enter puberty later generally had fathers who were active participants in care giving, had fathers who were supportive of the girls' mothers, and had positive relationships with their mothers.
