Childhood Experience and the Onset of Menarche: A Test of a Sociobiological Model.
Peer reviewed Peer reviewed

Used data from a longitudinal study of 16-year-old girls to test predictions about psychosocial factors in the onset of menarche. Found that family conflict and father's absence in childhood predicted an earlier age of menarche, and these factors in combination with weight showed some evidence of an additive influence on menarche.
