Study Objective:
An association between rapid repeat pregnancy (RRP; occurring within a birth interval of up to 24 months) and undesirable obstetric and perinatal outcomes has been shown, especially among adolescents and women without adequate schooling. The objective of this study was to evaluate the effect of the interaction between maternal schooling and age on the incidence of RRP. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: A nonconcurrent cohort study was carried out using probabilistic record linkage techniques. The 59,400 linked records of singleton live-born infants delivered in 2002 whose mothers were up to 29 years old and lived in Rio de Janeiro City were evaluated.
Results:
Compared with young adults with adequate schooling, the adjusted risk ratio for RRP for adolescents with inadequate schooling was 2.1 (95% confidence interval, 1.8-2.4). The attributable proportion was 0.16 (95% confidence interval, 0.02-0.29).
Conclusion:
Young maternal age and inadequate schooling interact, increasing RRP.

Gonadal and Placental Hormones
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair...
Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
