Objective: To explore recently/currently pregnant people's experiences and views about cannabis use during pregnancy and their associated support for policies that punish pregnant people who use cannabis.
Methods: A market research firm administered a survey (May-June 2022) to pregnant and recently pregnant people ages 18-49 regarding their attitudes about cannabis use policies and practices. We used multivariable regression to assess whether cannabis use and beliefs are associated with support for punishing people who use cannabis.
Objective: We examined if racial residential segregation (RRS) - a fundamental cause of disease - is independently associated with air pollution after accounting for other neighborhood and individual-level sociodemographic factors, to better understand its potential role as a confounder of air pollution-health studies.
Methods: We compiled data from eight large cohorts, restricting to non-Hispanic Black and White urban-residing participants observed at least once between 1999 and 2005. We used 2000 decennial census data to derive a spatial RRS measure (divergence index) and neighborhood socioeconomic status (NSES) index for participants' residing Census tracts, in addition to participant baseline data, to examine associations between RRS and sociodemographic factors (NSES, education, race) and residential exposure to spatiotemporal model-predicted PM and NO levels.
Importance: Since Dobbs v Jackson Women's Health Organization (Dobbs) removed federal abortion protections, people's views about alternative models of abortion care may have been impacted, yet research on this topic is limited.
Objective: To examine changes in national support for and personal interest in advance provision (AP) and over-the-counter (OTC) access to medication abortion.
Design, Setting, And Participants: Two nationally representative cross-sectional online surveys were administered to a market research firm's panel members who were assigned female at birth (AFAB) and aged 15 to 49 years from December 2021 to January 2022 (before Dobbs) and June to July 2023 (after Dobbs).
Background: With increasingly restricted access to facility-based abortion in the United States, pregnant people are increasingly relying on models of care that utilize history-based or no-test approaches to eligibility assessment. Minimal research has examined the accuracy of abortion patients' self-assessment of eligibility for medication abortion using their health history, a necessary step towards ensuring optimal access to history-based or no-test models, as well as potential over-the-counter access.
Objective: To examine the accuracy of pregnant people's eligibility for medication abortion determined using their self-reported health history as compared to clinician assessment with ultrasound and other tests.
Objective: We explored awareness of and attitudes about the safety of various methods people use to attempt to end a pregnancy without medical assistance, which we refer to in this study collectively as self-managed abortion (SMA).
Methods: In 2020, we invited individuals living in eight United States (US) states considered "hostile" to abortion rights or with a history of criminalizing abortions performed outside the formal healthcare system to participate in semi-structured telephone interviews regarding their attitudes toward these practices. We analyzed coded transcripts for content and themes.
