BACKGROUND: The biological mechanisms underlying the sex-related differences in risk of heart failure are still not well understood. The aim of this review was to provide an overview of the current evidence on the association between reproductive factors and risk of heart failure in women. METHODS: A systematic review of the literature was conducted. PubMed and Embase databases were searched for publications on the following reproductive factors as potential risk factors for heart failure in women: age at menarche, duration and frequency of the menstrual cycle, reproductive lifespan, use of contraception, polycystic ovarian syndrome (PCOS), pregnancy characteristics (e...

Mammographic % density, the proportion of fibroglandular tissue in the breast, is a strong risk factor for breast cancer, but its determinants in young women are unknown. We examined associations between magnetic resonance imaging (MRI) breast-tissue composition at age 21 years and prospectively-collected measures of body size and composition from birth to early adulthood, and markers of puberty (all standardized), in a sample of 500 nulliparous women from a pre-birth cohort of children born in Avon, England, in 1991-1992 and followed up to 2011-2014...

BACKGROUND/AIMS: Girls with low-birth weight (LBW) and postnatal weight catch-up tend to develop visceral and hepatic fat excess, which may be accompanied by an upregulated adrenarche with precocious pubarche (PP) and by a rapidly progressive puberty with early menarche and shorter stature. A pilot study suggested that metformin treatment for 4 years reduces central adiposity in LBW-PP girls and normalizes puberty and adult height. In this cohort, we studied the relationship between metformin treatment, bone maturation, and body composition...

OBJECTIVE: Breast cancer (BrCa) is the most frequently diagnosed cancer among females and second cancer after lung cancer in many societies. In Iran, the risk for BrCa is 1 in 35 and each year, 8000 new patients have been diagnosed with BrCa. Studies have shown that dietary components are implicated in the etiology of BrCa. The Index of Nutritional Quality (INQ) is a method of quantitative and qualitative analysis of single foods, meals, and diets. The aim of this study was to determine the usefulness of INQs in predicting BrCa risk...

PURPOSE: Mechanistic and observational data together support a role for prolactin in breast cancer development. Determinants of prolactin in Asian populations have not been meaningfully explored, despite the lower risk of breast cancer in Asian populations. METHODS: Determinants of plasma prolactin were evaluated in 442 postmenopausal women enrolled in the Singapore Chinese Health Study, a population-based prospective cohort study. At baseline all cohort members completed an in-person interview that elicited information on diet, menstrual and reproductive history, and lifestyle factors...

BACKGROUND: Previous studies of childhood psychosocial adversity and age at menarche mostly evaluated single or a few measures of adversity, and therefore could not quantify total psychosocial adversity. Limited knowledge is currently available regarding childhood psychosocial adversity in relation to age at menopause and reproductive lifespan. METHODS: We examined the associations of total and specific components of childhood psychosocial adversity with age at menarche (n=8984), age at menopause (n=945), and length of reproductive lifespan (n=841), in mothers participating in the Avon Longitudinal Study of Parents and Children...

BACKGROUND: Chamorro Pacific Islanders in the Mariana Islands have breast cancer incidence rates similar to, but mortality rates higher than, those of U.S. women. As breast cancer risk factors of women of the Mariana Islands may be unique because of ethnic and cultural differences, we studied established and suspected risk factors for breast cancer in this unstudied population. METHODS: From 2010-2013, we conducted retrospective case-control study of female breast cancer (104 cases and 185 controls) among women in the Mariana Islands...

BACKGROUND: Previous studies have shown that reproductive factors are differentially associated with breast cancer (BC) risk by subtypes. The aim of this study was to investigate associations between reproductive factors and BC subtypes, and whether these vary by age at diagnosis. METHODS: We used pooled data on tumor markers (estrogen and progesterone receptor, human epidermal growth factor receptor-2 (HER2)) and reproductive risk factors (parity, age at first full-time pregnancy (FFTP) and age at menarche) from 28,095 patients with invasive BC from 34 studies participating in the Breast Cancer Association Consortium (BCAC)...

BACKGROUND: Although the timing of menarche and menopause may be associated with cardiovascular disease (CVD), the entire reproductive life span has not been considered comprehensively as risk for CVD. We investigate the associations of reproductive life span duration and ages at menarche and menopause, induced by natural means or surgical bilateral oophorectomy, with incident CVD in women. METHODS AND RESULTS: Prospective cohort study of 73 814 Nurses' Health Study following participants without CVD, defined as incident coronary heart disease or stroke, from 1980 through 2012...

Globally, breast cancer is both the most commonly occurring cancer and the commonest cause of cancer death among women. Available data suggest that incidence and mortality in high-resource countries has been declining whereas incidence and mortality in low-resource countries has been increasing. This pattern is likely to be due to changing risk factor profiles and differences in access to breast cancer early detection and treatment. Risk factors for breast cancer include increasing age, race, menarche history, breast characteristics, reproductive patterns, hormone use, alcohol use, tobacco use, diet, physical activity, and body habitus...

Context: Recent genetic studies have identified genetic variants associated with age at pubertal onset. While Genome wide association studies reported associations of several hundred genetic variants with timing of self-reported age at menarche, a recent clinical study focussed on genetic variation affecting FSH action and clinically determined age at thelarche. The observations appear to be incongruent as effect sizes varied substantially between the studies. Alternatively, this may point to a differential impact of specific genetic loci on distinct pubertal events...
