Early life adversity, pubertal timing, and epigenetic age acceleration in adulthood.

Dev Psychobiol 2021 Jan 10. Epub 2021 Jan 10.

University of California, San Francisco, CA, USA.

Background: Given associations linking early life adversity, pubertal timing, and biological aging, we examined the direct and indirect effects of early life trauma on adult biological aging (via age of menarche).

Methods: Participants were premenopausal women (N = 183). Path models evaluated whether early life trauma predicted early pubertal timing and thereby, adult epigenetic age acceleration (indexed via four epigenetic clocks: Horvath DNAm Age, Hannum DNAm Age, DNAm PhenoAge, and DNAm GrimAge).

Associations Between Maternal Prepregnancy Body Mass Index and Gestational Weight Gain and Daughter's Age at Menarche: The Avon Longitudinal Study of Parents and Children.

Am J Epidemiol 2018 04;187(4):677-686

MRC Integrative Epidemiology Unit, University of Bristol, Bristol, United Kingdom.

Earlier puberty and menarche are associated with adverse health outcomes. Reported associations of maternal adiposity with daughter's age at menarche are inconsistent. We examined associations between maternal prepregnancy body mass index (BMI; weight (kg)/height (m)2) and gestational weight gain (GWG) and daughter's ages at menarche (n = 3,935 mother-offspring pairs), pubarche (Tanner stage 2 for pubic hair) (n = 2,942 pairs), and thelarche (Tanner stage 2 for breast development) (n = 2,942 pairs) in the Avon Longitudinal Study of Parents and Children, a prospective United Kingdom pregnancy cohort study (baseline 1991-1992).

Implications of Pubertal Timing for Romantic Relationship Quality Among Heterosexual and Sexual Minority Young Adults.

J Adolesc Health 2017 Dec 23;61(6):685-693. Epub 2017 Sep 23.

Department of Maternal and Child Health, Gillings School of Global Public Health, University of North Carolina at Chapel Hill, Chapel Hill, North Carolina; Carolina Population Center, University of North Carolina at Chapel Hill, Chapel Hill, North Carolina.

Purpose: Relative to on-time or late-maturing peers, girls who begin puberty early typically begin romantic and sexual experiences earlier; however, advanced pubertal status does not necessarily coincide with commensurate interpersonal skills necessary for healthy romantic relationships. Research is limited on the long-term implications of early puberty for relationship quality, and virtually nothing is known about the social implications of early timing for sexual minority females.

Methods: Using linear regression, we examine longitudinal associations between two measures of girls' pubertal timing (self-perceived timing and menarcheal age) and romantic relationship quality in young adulthood, stratified by sexual orientation, among 5,568 females in waves I and IV of the National Longitudinal Study of Adolescent to Adult Health.
