Health-related quality of life of young adult women with a history of premature adrenarche.

INTRODUCTION: Children with premature adrenarche (PA) have increased adrenal androgen concentrations and earlier pubertal development than their peers. Early sexual maturation and exposure to androgens have both been associated with an increased risk for neuropsychological adversities in adulthood. Such adversities would presumably influence the experienced health-related quality of life (HRQoL) of those affected. METHODS: A longitudinal case-control cohort study, in which 30 PA girls and 40 age-matched controls were followed from childhood to young adult age. The main outcome measure was the total 15D HRQoL score. In addition, we assessed specific dimensions of the questionnaire, the subjects' relationship statuses and living arrangements. RESULTS: There were no differences between the groups in the overall 15D scores (PA, 0.956 (0.052); control, 0.947 (0.055); p 0.482), or on any dimension of this instrument. CONCLUSION: The study suggests that a history of PA does not lead to impaired HRQoL in adult age.

Cardiorespiratory Fitness in Young Adult Women With a History of Premature Adrenarche.

Context: Premature adrenarche (PA) may predispose to some adverse long-term health outcomes. Cardiorespiratory fitness (CRF) is one of the strongest factors known to predict overall health, but no data exist on the CRF of women with a history of PA. Objective: To study if hyperandrogenism in childhood resulting from PA leads to a measurable difference in CRF between young adult PA and control women. Methods: A total of 25 women with PA and 36 age-matched controls were followed from prepubertal age until adulthood. Anthropometric measurements, body composition, biochemical, and lifestyle factors were assessed. The main outcome measure was maximal cycle ergometer test result at the mean age of 18.5 years. We also assessed prepubertal predicting factors for CRF with different linear regression models. Results: Though prepubertal children with PA were taller and heavier than their non-PA peers, there were no significant differences in height, body mass index, body composition, or physical activity in young adulthood. We observed no significant differences in any of the parameters of the maximal cycle ergometer test, including maximal load (P = .194) or peak oxygen consumption (P = .340). Hemodynamic responses of the groups were similar. None of the examined models or prepubertal factors significantly predicted CRF at adult age. Conclusion: This study suggests that hyperandrogenism in childhood/adolescence resulting from PA does not have a significant impact on adulthood CRF.

PCOS Features and Steroid Profiles Among Young Adult Women with a History of Premature Adrenarche.

CONTEXT: Premature adrenarche (PA) may increase the risk for polycystic ovary syndrome (PCOS). OBJECTIVE: To study features of PCOS in young adult women with a history of PA. METHODS: Thirty PA and 42 control females were followed from prepuberty to young adulthood (median age 18.1 years). The main outcome measures were ovarian function, the use of contraceptives, and clinical and biochemical indicators of hyperandrogenism. RESULTS: We found no differences in the use of hormonal contraceptives (50 vs 50%, PA vs controls, respectively; P > .999), indication for using contraceptives (P = .193), or in the history of oligo- (17 vs 26%, P = .392) and amenorrhea (0 vs 0%, P > .999). Among women not using hormonal contraceptives, those with a history of PA had a higher prevalence of hirsutism (27 vs 0%, P = .023) but not acne (87 vs 67%, P = .252). Steroid profiles were broadly comparable between the groups, but PA women had lower sex hormone-binding globulin (SHBG) concentrations (30.1 vs 62.4 nmol/L, P < .001) resulting in higher free androgen index (3.94 vs 2.14, P < .001). The difference in SHBG levels persisted through body mass index adjustment. SHBG correlated negatively with the homeostasis model assessment for insulin resistance (r -0.498, P = .003). Anti-Müllerian hormone concentrations were comparable between the groups (39.3 vs 32.1 pmol/L, P = .619). CONCLUSION: PA was not associated with evident ovarian dysfunction in young adult women. However, women with a history of PA had decreased SHBG levels and thus, increased bioavailability of circulating androgens.
