“…Extant research has also documented the long-term sequelae of early pubertal development in girls. Women who experienced early pubertal development, compared with their later maturing peers, tend to have higher levels of serum estradiol and lower sex hormone binding globulin concentrations that persist through 20–30 years of age; have shorter periods of adolescent subfertility (the time between menarche and attainment of fertile menstrual cycles); experience earlier ages at first sexual intercourse, first pregnancy, and first childbirth; display more negative implicit evaluations of men in early adulthood; attain lower educational outcomes and occupational status; engage in more aggressive/delinquent behavior as young adults; and are heavier, carry more body fat, and bear greater allostatic loads (cumulative biological “wear and tear”) in adolescence and early adulthood (Allsworth, Weitzen, & Boardman, 2005; Belles, Kunde, & Neumann, 2010; Emaus et al, 2008; Najman et al, 2009; van Lenthe, Kemper, & van Mechelen, 1996; reviewed in Ellis, 2004; Weichold, Silbereisen, & Schmitt-Rodermund, 2003). These effects can be conceptualized as part of a developmental continuum in which familial and ecological stressors in childhood forecast earlier pubertal maturation in girls (Belsky et al, 1991; Ellis, 2004; Ellis & Essex, 2007; Ellis, McFadyen-Ketchum, Dodge, Pettit, & Bates, 1999), which in turn regulates important dimensions of social and reproductive development (Belsky, Steinberg, Houts, & Halpern-Felsher, 2010; James, Ellis, Schlomer, & Garber, 2012; Trickett, Noll, & Putnam, 2011).…”
