Marginal Food Security Predicts Earlier Age at Menarche Among Girls from the 2009-2014 National Health and Nutrition Examination Surveys.

J Pediatr Adolesc Gynecol 2021 Apr 8. Epub 2021 Apr 8.

Department of Anthropology, Indiana University, 701 E Kirkwood Ave. Bloomington, IN, United States.

Purpose: This study analyzed the relationship between household food security and variation in age at menarche, as well as the connections between food insecurity, nutritional status, and allostatic load, among girls aged 12-15 years from the 2009-2014 United States National Health and Nutrition Examination Survey.

Methods: Data analysis included mean comparisons of age at menarche among household food security groups (high, marginal, low, and very low) as well as categorical variables known to associate with age at menarche (ethnicity, poverty status, body mass index (BMI), allostatic load, and milk consumption). Chi-square analyses tested the associations between household food security and additional categorical variables. Read More

Age at menarche, age at natural menopause, and risk of rheumatoid arthritis - a Mendelian randomization study.

Arthritis Res Ther 2021 Apr 9;23(1):108. Epub 2021 Apr 9.

Department of Clinical Neuroscience, Center for Molecular Medicine, Karolinska Institute, Tomtebodavägen 5, 17 177, Stockholm, Sweden.

Background: Hormonal reproductive factors have been suggested to play an important role in the etiology of rheumatoid arthritis (RA), an autoimmune inflammatory disorder affecting primarily women. We conducted a two-sample Mendelian randomization (MR) study examining three relevant exposures, age at menarche (AAM), age at natural menopause (ANM), and age at first birth (AFB) with the risk of RA.

Methods: We collected summary statistics from the hitherto largest GWAS conducted in AAM (N = 329,345), ANM (N = 69,360), AFB (N = 251,151), and RA (N = 14,361, N = 43,923), all of European ancestry. Read More

Markers of Low Iron Status Are Associated with Female Athlete Triad Risk Factors.

Med Sci Sports Exerc 2021 Mar 12. Epub 2021 Mar 12.

University of Michigan Medical School, Ann Arbor, MI Department of Physical Medicine and Rehabilitation, Harvard Medical School/Spaulding Rehabilitation Hospital, Boston, MA Department of Orthopaedic Surgery, Stanford University School of Medicine, Redwood City, CA Division of Adolescent Medicine, Department of Pediatrics, Stanford University School of Medicine, Palo Alto, CA Department of Epidemiology, University of Michigan School of Public Health, Ann Arbor, MI.

Purpose: The Female Athlete Triad (Triad) is common in female athletes. The Triad is caused by low energy availability (EA), which is often difficult to measure and has been postulated to be associated with low iron status. Here, we explore whether markers of low iron status may be associated with indicators of low EA including Triad risk factors. Read More

Socioeconomic Status Is Related to Pubertal Development in a German Cohort.

Horm Res Paediatr 2021 Mar 17:1-10. Epub 2021 Mar 17.

LIFE - Leipzig Research Center for Civilization Diseases, Leipzig University, Leipzig, Germany,

Introduction: Current health literature suggests that there has been a decline in the age of pubertal onset and that pubertal onset/duration of puberty may, besides weight status, be influenced by socioeconomic context.

Objective: The goal of this study was to determine whether pubertal onset/duration and puberty-triggering hormones luteinizing hormone (LH) and follicle-stimulating hormone (FSH) vary according to socioeconomic status (SES). Moreover, we aimed to propose cutoff values of serum LH and FSH for predicting gonadarche in boys. Read More

Women with Type 1 diabetes (T1D) experience a shorter reproductive period compared with nondiabetic women: the Pittsburgh Epidemiology of Diabetes Complications (EDC) study and the Study of Women's Health Across the Nation (SWAN).

Menopause 2021 Mar 1. Epub 2021 Mar 1.

Department of Epidemiology, Graduate School of Public Health, University of Pittsburgh, Pittsburgh, PA Department of Biostatistics, Graduate School of Public Health, University of Pittsburgh, Pittsburgh, PA Department of Psychiatry, University of Pittsburgh, Pittsburgh, PA.

Objective: Evidence suggests that insulin deficiency and hyperglycemia may disrupt the female reproductive system's normal function, leading to delayed menarche and premature ovarian aging. We thus compared the length of the reproductive period of women with type 1 diabetes (T1D) to women without diabetes.

Methods: Women with childhood-onset T1D (diagnosed in 1950-80) from the prospective Epidemiology of Diabetes Complications (EDC) study and nondiabetic women from the Pittsburgh site of the Study of Women's Health Across the Nation (SWAN) were studied. Read More

Department of Social Medicine, Osaka University Graduate School of Medicine, Osaka, Japan.

Prior studies reported the association of reproductive factors with breast cancer (BC), but the evidence is inconsistent. We conducted a pooled analysis of nine cohort studies in Japan to evaluate the impact of six reproductive factors (age at menarche/age at first birth/number of births/age at menopause/use of female hormones/breastfeeding) on BC incidence. We conducted analyses according to menopausal status at the baseline or at the diagnosis. Read More

Deep Learning Image Analysis of Benign Breast Disease to Identify Subsequent Risk of Breast Cancer.

JNCI Cancer Spectr 2021 Feb 11;5(1):pkaa119. Epub 2021 Jan 11.

Department of Pathology, Harvard Medical School, Beth Israel Deaconess Medical Center, Boston, MA, USA.

Curr Dev Nutr 2021 Feb 8;5(2):nzaa184. Epub 2021 Jan 8.

Division of Human Nutrition and Health, Wageningen University and Research, Wageningen, The Netherlands.

Investing in adolescent girls' nutrition is vital for health and for breaking the intergenerational cycle of malnutrition and deprivation, but limited knowledge on the type, timing, and efficacy of interventions delays progress.

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).
