Purpose In on-line forums, parents have been reporting that their children are experiencing what is described here as “rapid-onset gender dysphoria,” appearing for the first time during puberty or even after its completion. The onset of gender dysphoria seemed to occur in the context of belonging to a peer group where one, multiple, or even all of...

Study objective: Long acting reversible contraception, including the contraceptive implant, is recommended for teens and young women. However, some young women discontinue the implant early, and we seek to better understand their experiences. Design: / Setting / Participants: We conducted interviews with 16 females ages 14 to 24 presenting for r...

Recently, the hypothesis that state-level political context influences individuals' cultural values - the 'red states v. blue states' hypothesis - has been invoked to explain the hyper-polarisation of politics in the USA. To test this hypothesis, we examined individuals' knowledge about abortion in relation to the political context of their current...

Background Misinformation regarding the risks of abortion is prevalent and commonly includes medical inaccuracies about health, depression, infertility, and breast cancer. This pilot study sought to assess misinformation among abortion clients as well as the origin(s) of their abortion knowledge. Study Design Women who presented to the Mount Sinai...

Objective: Misinformation about the risks and sequelae of abortion is widespread. The purpose of this study was to examine whether women having an abortion who believe that there should be restrictions to abortion (i.e., that some other women should not be allowed to have an abortion) also believe this misinformation about the health risks associa...

The objective of this research was to examine individuals' knowledge about abortion in the context of their knowledge about other sexual and reproductive health (SRH) issues, including contraception, abortion, pregnancy, and birth. During August 2012, we administered an online questionnaire to a randomly selected sample of 639 men and women of repr...

Lab Experience: Measuring Genomic Imprinting Status and microRNA Expression in Human Placentas of the National Children’s Study

Goal: Chorionic vascular surface networks are well recognized to be highly variable but they have mainly been described in relation to the site of umbilical cord insertion; their description is limited to nullmagistralnull or nulldisperse,null terms of problematic utility for quantitative analysis. However, digital images have rendered these networ...

Goals: We have previously demonstrated that chorionic plate shape is predictive of placental functional efficiency and birth weight in a birth cohort collected at a single institution. The NCS will receive both fresh and formalin fixed placentae. The extent to which information generated from images under these different circumstances is equivalent...

Introduction: The National Children's Study (NCS) will recruit and follow a cohort of 100,000 United States children from before birth until age 21. The goal is to improve the health and well-being of children and contribute to understanding the role that many factors have on health and disease. The focus of this research is to develop methods for...

Introduction: The National Collaborative Perinatal Project (CPP) is the largest United States birth cohort and utilized placental measurement protocols as set forth by Kurt Benirschke, MD in 1961. We here focus on measures of placental shape and compare the estimations of placental volume obtained using CPP protocols, 2D digital images of sliced pl...

Goals: Conventionally, placentas have been suggested to be sliced at one centimeter intervals, but practically this often is impossible. We implemented a simpler method of slicing in eighths. Placentas with variable shape may have had the most problematic intrauterine environments, and thus be of greatest interest to the NCS. We sought to determine...

Overweight and obesity are chronic conditions affecting approximately 68% of adults and 31.7% of children ages 2‐19 in the United States. Our aim was to apply an ecological model of health literacy to better understand consumer needs relating to overweight and obesity, and use this information to develop an Obesity Action Kit for the New York City...

Background/Significance: A vaccine to prevent HPV infection with the four types of Human Papilloma Virus (HPV) responsible for the majority of cervical cancers and genital warts was approved by the FDA in 2006. There are many challenges to obtaining and using information about HPV and HPV vaccination including socio-cultural beliefs and attitudes a...

Currently in the United States, women who have abortions face a societal culture in which disapproval, stigma, and misinformation about the risks and sequelae of abortion are common. The purpose of this study is to pilot test an intervention that introduces abortion patients to a "culture of support" by providing validating messages and information...

Objective: The purpose of this study is to pilot a prophylactic intervention for post-abortion patients that addresses stigma, provides information about legitimate and harmful support services, and reinforces positive messages about why women make reproductive decisions. Data-collection methods: This experimental, non-randomized study pilots an i...
