Background: The Women's Health Needs Study (WHNS) collected information on the health characteristics, needs, and experiences, including female genital mutilation (FGM) experiences, attitudes, and beliefs, of women aged 18 to 49 years who were born, or whose mothers were born, in a country where FGM is prevalent living in the US. The purpose of this paper is to describe the WHNS design, methods, strengths and limitations, as well as select demographic and health-related characteristics of participants.

Methods: We conducted a cross-sectional survey from November 2020 -June 2021 in four US metropolitan areas, using a hybrid venue-based sampling (VBS) and respondent-driven sampling (RDS) approach to identify women for recruitment.

Article Synopsis
  • Antenatal care can help assess the prevalence of antibodies against COVID-19 and their duration in pregnant individuals, which could be important for protecting both mothers and newborns during and after pregnancy.
  • The study involved screening pregnant people in Seattle for COVID-19 antibodies and included both a cross-sectional study to measure prevalence and a prospective cohort study to analyze antibody responses over time.
  • Results showed that 5% of the individuals screened had COVID-19 antibodies, with some being asymptomatic; in the cohort study, 80% of participants were found to have antibodies during pregnancy, although nearly half lost these antibodies by the time of delivery.*

To identify research and gaps in literature about FGM/C-related attitudes and experiences among individuals from FGM/C-practicing countries living in the United States, we conducted a scoping review guided by Arksey and O'Malley's framework. We searched Medline (OVID), Embase (OVID), PubMed, and SCOPUS and conducted a grey literature search for studies assessing attitudes or experiences related to FGM/C with data collected directly from individuals from FGM/C-practicing countries living in the United States. The search yielded 417 studies, and 40 met the inclusion criteria.

Article Synopsis
  • The review highlights that disasters caused by natural hazards have increasingly affected women's reproductive health, leading to potential challenges in fertility and contraception post-disaster.
  • Researchers conducted a comprehensive literature search across multiple databases to identify studies from 1980 to early 2022 that focused on women aged 15-49 and their reproductive health in the context of disasters.
  • The review concluded that there are significant gaps in the current research regarding clearly defining disaster exposure and assessing fertility and contraception, suggesting a need for more rigorous studies to understand the impact of these disasters on women's reproductive health.

Objective: To investigate whether rates of self-reported Woman's Condom (WC) clinical failure and semen exposure from a functionality study are comparable to results from a contraceptive efficacy substudy.

Study Design: We structured our comparative analysis to assess whether functionality studies might credibly supplant contraceptive efficacy studies when evaluating new female condom products. Couples not at risk of pregnancy in the functionality (breakage/slippage/invagination/penile misdirection) study and women in the contraceptive efficacy study completed condom self-reports and collected precoital and postcoital vaginal samples for up to four uses of the WC.

Objective: Prostate-specific antigen (PSA) is the best established biomarker of semen exposure. PSA in vaginal fluid returns to pre-exposure concentrations within 24-48 h, but the speed of decay during the first 10 h is unknown. We sought to determine how fast PSA concentrations decline during the first 10 h after exposure to semen.

Background: There is limited information on rates of STIs in Jamaica due to syndromic management and limited aetiological surveillance. We examined the prevalence of (CT), (NG) and (TV) and characteristics associated with STIs among sexually active women who participated in a randomised trial of a progestin implant initiation in Jamaica (the Sino-Implant Study (SIS)).

Methods: SIS was a randomised trial conducted in Kingston, Jamaica, from 2012 to 2014 to evaluate whether initiation of the Sino-Implant (II) led to more unprotected sex among women ages 18-44 years.

Background: Self-reported unprotected vaginal sex seems to increase risk of bacterial vaginosis (BV). However, the validity of self-reports is questionable, given their inconsistency with more objective measures of recent semen exposure such as detection of prostate-specific antigen (PSA). We examined whether recent unprotected sex, as measured both by PSA detection on vaginal swabs and by self-report, was associated with increased BV recurrence.

Objective: To evaluate whether initiation of a contraceptive implant, a method of long-acting reversible contraception, reduces condom use, as measured by a biomarker of recent semen exposure [prostate-specific antigen (PSA)].

Study Design: We conducted a randomized controlled clinical trial in which 414 Jamaican women at high risk for sexually transmitted infections (STIs) attending family planning clinics received the contraceptive implant at baseline ("immediate" insertion arm, N=208) or at the end ("delayed" insertion arm, N=206) of a 3-month study period. Participants were tested for PSA at baseline and two follow-up study visits and were asked about their sexual activity and condom use.

Objectives: Previous studies have found social cognitive theory (SCT)-framed interventions are successful for improving condom use and reducing sexually transmitted infections (STIs). We conducted a secondary analysis of behavioural data from the Safe in the City intervention trial (2003-2005) to investigate the influence of SCT constructs on study participants' self-reported use of condoms at last intercourse.

Methods: The main trial was conducted from 2003 to 2005 at three public US STI clinics.

Biomarkers of semen exposure have been used in studies investigating the safety and efficacy of barrier methods of contraception. They have been used as objective indicators of semen exposure when studying sexual behaviors and in human immunodeficiency virus/sexually transmitted infection research interventions where participants are advised to avoid unprotected sex. Semen biomarkers have also been used to assess or validate self-reported sexual behaviors or condom use in reproductive health settings.

HIV-infected young women in the United States have important reproductive health needs that are made more complex by their HIV status. We searched Pubmed and relevant bibliographies to identify 32 articles published from 2001 to July 2012 that described the prevalence, correlates, and characteristics of the sexual activity, relationships, pregnancy intentions, HIV status disclosure, and contraceptive and condom use among US HIV-infected adolescents and young women. Our synthesis of those articles found that, like youth not infected with HIV, substantial proportions of HIV-infected youth were sexually active, and most sought romantic or sexual relationships, though their serostatus may have affected the pace of physical and emotional intimacy.
