Age at puberty and father absence in a national probability sample.

The relations between intactness of the parental unit (e.g., father absent at age 14) and pubertal timing in both men and women were examined in a US national probability sample. In both men and women, an absent father at age 14 predicted an earlier age of puberty (e.g., early menarche or voice change). There was little evidence that an absent mother or the presence of a stepfather, independent of a father's absence, was related to early puberty in either men or women. The results extend previous research and suggest that certain psychosocial factors (i.e., father absence) may affect growth and development in both adolescent girls and boys.
