Preconception health

P A Stapleton, C R McBride, J Yi, A B Abukabda, T R Nurkiewicz
Preconceptive health encompasses male and female reproductive capability. In females, this takes into account each of the stages of the estrous cycle. Microvascular reactivity varies throughout the estrous cycle in response to hormonal changes and in preparation for pregnancy. Microvascular alterations in response to engineered nanomaterial (ENM) exposure have been described within 24-hours of inhalation; however, the impact upon the uterine vasculature at differing estrous stages and at late-stage pregnancy is unclear...

BACKGROUND: Globally, about five per cent of children are born with congenital or genetic disorders. The most common autosomal recessive conditions are thalassaemia, sickle cell disease, cystic fibrosis and Tay-Sachs disease, with higher carrier rates in specific patient populations. Identifying and counselling couples at genetic risk of the conditions before pregnancy enables them to make fully informed reproductive decisions, with some of these choices not being available if genetic counselling is only offered in an antenatal setting...

BACKGROUND: Prior studies indicate associations between preconception adversities and risk of miscarriage, but few have considered type (e.g., financial, substance use, abuse) or timing (e.g., childhood, adulthood) of adversities. We examined relationships between life course adversities in multiple domains and probability of miscarriage. METHODS: Data came from women with at least one previous pregnancy in the Pregnancy Outcomes and Community Health (1998-2004) study (n = 2,106)...

Preconception care (PCC) is a preventive strategy for maternal and perinatal morbidity and mortality. This study aimed to assess the level of awareness and utilisation of PCC services. A descriptive cross-sectional survey was conducted at a teaching hospital. Interviewer-administered questionnaires were used to extract information. A total of 450 participants responded; 44.2% (190/450) were aware, 31.7% (143/450) had good knowledge, while only 10.3% (46/450) received PCC. Health care providers were the main source of information (77...

BACKGROUND: Developmental programming of the embryo is controlled by genetic information but also dictated by epigenetic information contained in spermatozoa. Lifestyle and environmental factors not only influence health in one individual but can also affect the phenotype of the following generations. This is mediated via epigenetic inheritance i.e., gametic transmission of environmentally-driven epigenetic information to the offspring. Evidence is accumulating that preconceptional exposure to certain lifestyle and environmental factors, such as diet, physical activity, and smoking, affects the phenotype of the next generation through remodeling of the epigenetic blueprint of spermatozoa...

Allergies are complex diseases that result from interactions between multiple genetic and environmental factors. However, the increase in allergies observed in the past decades is explained exclusively by environmental changes occurring in the same period. Presently, the exposome, the totality of specific and nonspecific external environmental exposures (external exposome) to which a subject is exposed from preconception onward and their consequences at the organ and cell levels (internal exposome), is being considered to explain the inception, development, and exacerbations of allergic diseases...

AIM: To compare young adults' expectations of psychiatric treatment to their actual experiences and identify myths and assumptions that youth might hold prior to receiving care. METHODS: We interviewed youth who engaged in at least 4 months of treatment at the First Episode Mood and Anxiety Program to theme saturation (N = 20). They were asked about their experience of treatment and the expectations they had prior to care. Transcribed interviews were analysed for themes...

Introduction Unintended pregnancy has been a concerning public health problem for decades. As we begin to understand the complexities of pregnancy intention and how women experience these pregnancies, reproductive life planning offers a paradigm shift. Methods Reproductive life planning is a patient-centered approach that places a patient's reproductive preferences-whether concrete or ambivalent-at the forefront of her clinical care. Results This process grants women and men the opportunity to consider how reproduction fits within the context of their broader lives...

STUDY QUESTION: Are biomarkers of preconception stress associated with pregnancy loss? SUMMARY ANSWER: Preconception stress, as measured by basal salivary cortisol and alpha-amylase concentrations, is not associated with pregnancy loss. WHAT IS KNOWN ALREADY: Many studies, most of which have been retrospective, have identified an association between stressful life events and perceived stress and miscarriage. STUDY DESIGN, SIZE, DURATION: A prospective pregnancy study with preconception enrollment was conducted between 2005 and 2009...

BACKGROUND: Although pregnancy concentrations of some phenols have been associated with infant size at birth, there is limited data on the effect of preconception exposure. OBJECTIVE: We aimed to examine paternal and maternal preconception and maternal prenatal urinary phenol concentrations in relation to birth weight and head circumference. METHODS: We evaluated 346 singletons born to 346 mothers and 184 fathers (184 couples) from a prospective preconception cohort of subfertile couples from the Environment and Reproductive Health (EARTH) Study in Boston, USA...

While the risks of maternal alcohol abuse during pregnancy are well-established, several preclinical studies suggest that chronic preconception alcohol consumption by either parent may also have significance consequences for offspring health and development. Notably, since isogenic male mice used in these studies are not involved in gestation or rearing of offspring, the cross-generational effects of paternal alcohol exposure suggest a germline-based epigenetic mechanism. Many recent studies have demonstrated that the effects of paternal environmental exposures such as stress or malnutrition can be transmitted to the next generation via alterations to small noncoding RNAs in sperm...

Objective To measure the association of preconception health insurance status with preconception health among women in New York City, and examine whether this association is modified by race/ethnicity. Methods Using data from the New York City Pregnancy Risk Assessment Monitoring System 2009-2011 (n = 3929), we created a "Preconception Health Score" (PHS) capturing modifiable behaviors, healthcare services utilization, pregnancy intention, and timely entry into prenatal care. We then built multivariable logistic regression models to measure the association of PHS with health insurance status and race/ethnicity...

PURPOSE OF REVIEW: Women with diabetes who have unplanned pregnancies and uncontrolled blood sugars are at a higher risk for maternal and fetal morbidities and mortalities. Preconception counseling (PC) has been shown to decrease the risks and improve health outcomes. From 2009 to 2017, the American Diabetes Association has recommended that preconception counseling be given at each clinic visit for all women with diabetes of childbearing age starting at puberty (prior to sexual debut)...

The reproductive-aged women have to face physiological and psychological challenges as long as they plan to conceive. However, most previous studies focused on depression and anxiety during pregnancy. This study aimed to investigate the association among preconception depression, anxiety, and social support of the Chinese reproductive-aged women. Nine-hundred five reproductive-aged women who planned to conceive for the first or second time in the next three months were recruited through the Maternity and Child Healthcare Hospital and Obstetrics and Gynecology Hospital from three provinces in China...

Advances in technology and the promise of personalized health care are driving greater use of genome sequencing (GS) for a variety of clinical scenarios. As health systems consider adopting GS, they need to understand the impact of GS on the organization and cost of care. While research has documented a dramatic decrease in the cost of sequencing and interpreting GS, few studies have examined how GS impacts genetic counseling workloads. This study examined the time needed to provide genetic counseling for GS in the context of preconception carrier screening...

Recent efforts to explain the stark social and racial disparities in adverse birth outcomes that have persisted for decades in the U.S. have looked beyond prenatal factors, to explore preconception social conditions that may influence perinatal health via dysregulation of physiologic processes. The extant evidence supporting this link however remains limited, both due to a lack of data and theory. To address the latter, this manuscript generates a structured set of theoretical insights that further develop the link between two preconception social conditions - place and social relationships - and perinatal health...
