Examining the Social Aspects of Pregnancy Tracking Applications

Pregnancy is a significant but stressful life transition, requiring effort from multiple stakeholders including expectant parents, family members, and friends to navigate. Existing work has primarily focused on understanding and supporting the technology use of pregnant people, neglecting other stakeholders' needs and participation. We therefore consider how pregnancy tracking apps both improve and interfere with the reconfiguration of social relationships caused by pregnancy, drawing on insights from family sociology to examine how these relationships evolve over pregnancy and the transition to parenthood. We reviewed the features of 20 pregnancy tracking apps, and analyzed 4,709 public reviews of them, finding that stakeholders used apps to bond with one another around the excitement of pregnancy, build a prenatal relationship with the fetus, and co-manage pregnancy-related logistical tasks. We find that not accounting for fetal demographics and users' identities, along with socio-cultural norms around gender and parenting roles, often inhibit these collaborative practices. We therefore suggest designing collaborative pregnancy tracking technology that considers both inclusiveness and specificity regarding stakeholders' different roles and relationships to pregnancy.

Association of Receipt of Opioid Prescription for Acute Post-Delivery Pain Management with Buprenorphine Discontinuation among Postpartum People with Opioid Use Disorder

Buprenorphine is a safe and effective medication to treat opioid use disorder (OUD) in pregnant patients and is intended to be continued throughout pregnancy, delivery, and at least the one-year postpartum period. However, delivery often involves the need for acute pain management with opioid medications, such as after a cesarean section. For patients receiving buprenorphine, the provision of prescription opioids may negatively impact OUD treatment outcomes; however, not optimally managing acute pain may also impede OUD treatment benefit. Evidence is needed to disentangle the impacts of opioid prescription provision and methods of pain management in the immediate postpartum period on OUD treatment trajectories, ultimately to inform clinical guidelines tailored to the unique needs of pregnant and postpartum people receiving buprenorphine. Accordingly, this study took an initial step towards this goal to conduct a secondary analysis of a retrospective cohort of pregnant patients taking buprenorphine for OUD at the time of delivery (n = 142) to determine whether receipt of an opioid prescription at birth hospitalization discharge was associated with the time of buprenorphine discontinuation within the 12 months following delivery. Among the sample, 26% (n = 37) were prescribed an opioid at the time of birth hospitalization discharge. The number of weeks post-delivery until buprenorphine discontinuation occurred was shorter amongst patients who were prescribed an opioid (median 11 weeks) compared to patients who were not prescribed an opioid (median 39 weeks; p < 0.001 by Mann–Whitney U test). However, a Cox regression model reported that receipt of an opioid prescription following delivery did not significantly increase the hazard ratio for buprenorphine discontinuation. In other words, OUD patients not prescribed an opioid at birth hospitalization discharge continued their buprenorphine for a longer median duration after delivery compared to their counterparts who received prescription opioids; yet, this finding did not reach statistical significance when taking into account additional clinical variables. The findings indicate how further research is warranted to inform evidence-based post-delivery pain practices for postpartum OUD treatment patients.

Association Between Maternal Body Mass Index and Fetal Acidosis in Term Twin Pregnancies: A Retrospective Cohort Study

ObjectivesGiven the increased risk of fetal acidosis in singleton neonates born to pregnant people with an elevated BMI, our objective was to evaluate the association between pre-pregnancy/first-trimester BMI and fetal acidosis among term twin pregnancies. MethodsRetrospective study of pregnant people with twin gestation and their term infants admitted to our centre between 2014 and 2019. Using a generalized estimating equation, the association between maternal BMI and fetal acidosis was determined using odds ratios (ORs) with 95% CIs. A two-sided P < 0.05 was considered significant. ResultsA total of 275 pregnant people and 550 infants were analyzed. The number (%) of pregnancies in each BMI class were 10 (4%) underweight, 155 (56%) normal weight, 66 (24%) overweight, 22 (8%) class I, 9 (3%) class II, and 13 (5%) class III. The prevalence of maternal diabetes and hypertension was highest in class III (31%) and class II (44%), respectively. Fetal acidosis was diagnosed in 35 (6%) infants. After adjusting for confounders (maternal age, diabetes, and hypertension), infants born to those with elevated BMI did not have increased odds of fetal acidosis compared to those born to underweight and normal weight group (OR 1.29; 95% CI 0.38–4.41 for class I, P = 0.67 and OR 2.80; 95% CI 0.62–12.62 for the combined classes II and III, P = 0.18). ConclusionsMaternal BMI was not associated with fetal acidosis in term twin pregnancies. Further research is required to corroborate study findings due to small sample size.

Access to and interest in human milk research opportunities among Black pregnant and postpartum people.

Concerns exist regarding biomedical research participation in marginalized and historically disadvantaged communities. The purpose of this study was to understand critical barriers to participation in human milk research from the perspective of Black pregnant and postpartum people. A national sample of Black pregnant and postpartum people (n = 104) was recruited to complete a cross-sectional online survey informed by the Life Course Perspective. Survey questions assessed research experiences and preferences, particularly related to human milk research, knowledge of historical events/policies targeting Black communities, and demographic characteristics. A socio-economic composite score was calculated as an indicator of socio-economic advantage. Survey data were summarized descriptively and potential correlates of research engagement were evaluated. Most (69%, n = 71) respondents reported previous participation in a research study, yet only 8 (8%) reported ever being asked to participate in a breastfeeding/chestfeeding or human milk study, and one respondent was unsure. Despite so few having been asked, 59% (n = 61) of respondents indicated they would donate breast/human milk to research if asked. Respondent characteristics associated with prior research participation included having greater socio-economic advantage (p = 0.027) and greater knowledge of discriminatory historical events/policies (p < 0.001). In contrast, the only respondent characteristic associated with willingness to donate human milk to research was younger age (p = 0.002). Our findings suggest that Black pregnant and postpartum people are interested in biomedical research, specifically human milk and lactation research. However, greater intentionality and targeted recruitment of this underrepresented population is needed to increase diversity among human milk and lactation study samples. Structural and community-based interventions, informed by community members, are needed to address concerns and improve participant engagement.

Listening to Black Pregnant and Postpartum People: Using Technology to Enhance Equity in Screening and Treatment of Perinatal Mental Health and Substance Use Disorders.

Perinatal mood and anxiety disorders (PMADs), perinatal substance use disorders (PSUDs), and intimate partner violence (IPV) are leading causes of pregnancy-related deaths in the United States. Screening and referral for PMADs, PSUDs and IPV is recommended, however, racial disparities are prominent: Black pregnant and postpartum people (PPP) are less likely to be screened and attend treatment compared to White PPP. We conducted qualitative interviews to better understand the experience of Black PPP who used a text/phone-based screening and referral program for PMADs/PSUDs and IPV-Listening to Women and Pregnant and Postpartum People (LTWP). We previously demonstrated that LTWP led to a significant reduction in racial disparities compared to in-person screening and referral, and through the current study, sought to identify facilitators of PMAD/PSUD symptom endorsement and treatment attendance. Semi-structured interviews were conducted with 68 Black PPP who were or had been pregnant within the last 24 months, and who either had or did not have a PMAD or PSUD. Participants were enrolled in LTWP and provided feedback on their experience. Using a grounded theory approach, four themes emerged: usability, comfort, necessity, and recommendations. Ease of use, brevity, convenience, and comfort in discussing mental health and substance use via text were highlighted. Need for a program like LTWP in Black communities was discussed, given the reduction in perceived judgement and access to trusted information and resources for PMADs/PSUDs, which may lessen stigma. These qualitative findings illuminate how technology-based adaptations to behavioral health screening and referral can reduce perceived negative judgment and facilitate identification and referral to treatment, thereby more adequately meeting needs of Black PPP.

Patient-centered respectful maternity care: a factor analysis contextualizing marginalized identities, trust, and informed choice

BackgroundIncreasing rates of maternal mortality and morbidity, coupled with ever-widening racial health disparities in maternal health outcomes, indicate that radical improvements need to be made in the delivery of maternity care. This study explored the provision of patient-centered maternity care from the perspective of pregnant and postpartum people; experiences of respect and autonomy were examined through the multi-dimensional contexts of identity, relational trust, and protection of informed choices.MethodsWe conducted primary data collection among individuals who experienced a pregnancy in the five years preceding the survey (N = 484) using the validated Mothers on Respect Index (MORi) and Mothers Autonomy in Decision Making (MADM) scale. We conducted an exploratory factor analysis (EFA) which produced three factor variables: trust, informed choice, and identity. Using these factor variables as dependent variables, we conducted bivariate and multivariate analysis to examine the relationship between these factor variables and social marginalization, as measured by race, disability, justice-involvement, and other social risk factors, such as food and housing insecurity.ResultsResults of our bivariate and multivariate models generally confirmed our hypothesis that increased social marginalization would be associated with decreased experiences of maternity care that was perceived as respectful and protective of individual autonomy. Most notably, AI/AN individuals, individuals who are disabled, and individuals who had at least one social risk factor were more likely to report experiencing identity-related disrespect and violations of their autonomy.ConclusionsIn light of the findings that emphasize the importance of patient identity in their experience in the healthcare system, patient-centered and respectful maternity care must be provided within a broader social context that recognizes unequal power dynamics between patient and provider, historical trauma, and marginalization. Provider- and facility-level interventions that improve patient experiences and health outcomes will be more effective if they are contextualized and informed by an understanding of how patients’ identities and traumas shape their healthcare experience, health-seeking behaviors, and potential to benefit from clinical interventions and therapies.

Characteristics of women concordant and discordant for urine drug screens for cannabis exposure and self-reported cannabis use during pregnancy

BackgroundIncreasing cannabis use among pregnant people and equivocal evidence linking prenatal cannabis exposure to adverse outcomes in offspring highlights the need to understand its potential impact on pregnancy and child outcomes. Assessing cannabis use during pregnancy remains a major challenge with potential influences of stigma on self-report as well as detection limitations of easily collected biological matrices. ObjectiveThis descriptive study examined the concordance between self-reported (SR) cannabis use and urine drug screen (UDS) detection of cannabis exposure during the first trimester of pregnancy and characterized concordant and discordant groups for sociodemographic factors, modes of use, secondhand exposure to cannabis and tobacco, and alcohol use and cotinine positivity. Study designThe Cannabis Use During Development and Early Life (CUDDEL) Study is an ongoing longitudinal study that recruits pregnant individuals presenting for obstetric care, who report lifetime cannabis use as well as using (n = 289) or not using cannabis (n = 169) during pregnancy. During the first trimester pregnancy visit, SR of cannabis use and a UDS for cannabis, other illicit drugs and nicotine are acquired from eligible participants, of whom 333 as of 05/01/2023 had both. ResultsUsing available CUDDEL Study data on both SR and UDS (n = 333; age 26.6 ± 4.7; 88.6% Black; 45.4% below federal poverty threshold; 56.5% with paid employment; 89% with high school education; 22% first pregnancy; 12.3 ± 3.6 weeks gestation), we classified pregnant individuals with SR and UDS data into 4 groups based on concordance (k = 0.49 [95% C.I. 0.40–0.58]) between SR cannabis use and UDS cannabis detection during the first trimester: 1) SR+/UDS+ (n = 107); 2) SR-/UDS- (n = 142); 3) SR+/UDS- (n = 44); 4) SR-/UDS+ (n = 40). Those who were SR+/UDS- reported less frequent cannabis use and fewer hours under the influence of cannabis during their pregnancy. Those who were SR-/UDS+ were more likely to have joined the study at a lower gestational age with 62.5% reporting cannabis use during their pregnancy prior to being aware that they were pregnant. Of the 40 SR-/UDS+ women, 14 (i.e., 35%) reported past month secondhand exposure, or blunt usage. In the subset of individuals with SR and UDS available at trimester 2 (N = 160) and 3 (N = 140), concordant groups were mostly stable and > 50% of those in the discordant groups became concordant by the second trimester. Classifying individuals as exposed or not exposed who were SR+ and/or UDS+ resulted in minor changes in group status based on self-report at screening. ConclusionOverall, there was moderate concordance between SR and UDS for cannabis use/exposure during pregnancy. Instances of SR+/UDS- discordancy may partially be attributable to lower levels of use that are not detected on UDS. SR-/UDS+ discordancy may arise from recent use prior to knowledge of pregnancy, extreme secondhand exposure, deception, and challenges with completing questionnaires. Acquiring both self-report and biological detection of cannabis use/exposure allows for the examination of convergent evidence. Classifying those who are SR+ and/or UDS+ as individuals who used cannabis during their first trimester after being aware of their pregnancy resulted in only a minor change in exposure status; thus, relying on self-report screening, at least in this population and within this sociocultural context likely provides an adequate approximation of cannabis use during pregnancy.

Society for Maternal-Fetal Medicine Position Statement: Gun violence and pregnancy

The Society for Maternal-Fetal Medicine (SMFM) acknowledges gun violence as a public health crisis in the United States, with a significant impact on pregnant and postpartum people. We recognize the urgent need for a robust, equitable, data-driven approach to mitigate the impact of access to firearms and accompanying violence on pregnant and postpartum individuals and communities. As such, SMFM endorses the following policy principles:- SMFM calls on relevant government agencies and public funders to support and finance anti-violence and firearm safety research, public health surveillance activities, education, and other initiatives. These initiatives should acknowledge and address the connection between access to firearms and the health and safety of pregnant and postpartum people, as well as their families and communities.- SMFM strongly opposes legislation or regulations that impede or limit clinician-patient discussions about firearms.- SMFM calls for enhanced access to mental health care services for pregnant and postpartum people.- SMFM calls for additional support for individuals experiencing intimate partner violence and their families.- SMFM supports the creation of and funding for training programs for maternal-fetal medicine (MFM) subspecialists and all clinicians about firearms and domestic violence prevention.- SMFM supports laws and regulations that restrict individuals with protective or restraining orders and those with intimate partner violence or stalking convictions from purchasing and owning firearms.

Attitudes Toward COVID-19 Vaccines Among Pregnant and Recently Pregnant Individuals

Pregnant people and infants are at high risk of severe COVID-19 outcomes. Understanding changes in attitudes toward COVID-19 vaccines among pregnant and recently pregnant people is important for public health messaging. To assess attitudinal trends regarding COVID-19 vaccines by (1) vaccination status and (2) race, ethnicity, and language among samples of pregnant and recently pregnant Vaccine Safety Datalink (VSD) members from 2021 to 2023. This cross-sectional surveye study included pregnant or recently pregnant members of the VSD, a collaboration of 13 health care systems and the US Centers for Disease Control and Prevention. Unvaccinated, non-Hispanic Black, and Spanish-speaking members were oversampled. Wave 1 took place from October 2021 to February 2022, and wave 2 took place from November 2022 to February 2023. Data were analyzed from May 2022 to September 2023. Self-reported or electronic health record (EHR)-derived race, ethnicity, and preferred language. Self-reported vaccination status and attitudes toward monovalent (wave 1) or bivalent Omicron booster (wave 2) COVID-19 vaccines. Sample- and response-weighted analyses assessed attitudes by vaccination status and 3 race, ethnicity, and language groupings of interest. There were 1227 respondents; all identified as female, the mean (SD) age was 31.7 (5.6) years, 356 (29.0%) identified as Black race, 555 (45.2%) identified as Hispanic ethnicity, and 445 (36.3%) preferred the Spanish language. Response rates were 43.5% for wave 1 (652 of 1500 individuals sampled) and 39.5% for wave 2 (575 of 1456 individuals sampled). Respondents were more likely than nonrespondents to be White, non-Hispanic, and vaccinated per EHR. Overall, 76.8% (95% CI, 71.5%-82.2%) reported 1 or more COVID-19 vaccinations; Spanish-speaking Hispanic respondents had the highest weighted proportion of respondents with 1 or more vaccination. Weighted estimates of somewhat or strongly agreeing that COVID-19 vaccines are safe decreased from wave 1 to 2 for respondents who reported 1 or more vaccinations (76% vs 50%; χ21 = 7.8; P < .001), non-Hispanic White respondents (72% vs 43%; χ21 = 5.4; P = .02), and Spanish-speaking Hispanic respondents (76% vs 53%; χ21 = 22.8; P = .002). Decreasing confidence in COVID-19 vaccine safety in a large, diverse pregnant and recently pregnant insured population is a public health concern.

Associations Among Plurisexual Identity, Intimate Partner Violence, Reproductive Coercion, and Parental Monitoring in a Sample of Adolescent and Young Adult Pregnant People.

Purpose: The goal of this study was to examine plurisexual identity, intimate partner violence (IPV), reproductive coercion, and parental monitoring among pregnant 13-21-year-olds. Methods: We conducted a cross-sectional analysis of data collected from a cohort of pregnant adolescents and young adults between October 2019 and May 2023 (n = 398). Logistic regression was completed to assess IPV and reproductive coercion as a function of plurisexual identity. Next, we assessed potential interactions between parental monitoring and plurisexual identity and examined IPV and reproductive coercion as a function of parental monitoring for the full sample and stratified by plurisexuality. Results: Plurisexual identity was associated with IPV (adjusted odds ratio [aOR] = 2.3; confidence interval [CI]: 1.4-4.0). IPV was inversely related to parental monitoring among plurisexual participants (aOR: 0.51; CI: 0.32-0.82), but this association was not significant for heterosexual participants (aOR: 1.1; CI: 0.75-1.6). Conclusions: This work demonstrates the importance of parental monitoring in supporting young plurisexual pregnant people.

Deviating from the Norm? The Pregnant Body in Scandinavian Health Law

Abstract This article explores how the political ideal of data interacts with the legal entitlement of autonomy in the care of pregnant people guided by feminist theory and critical approaches to data. Using Scandinavian legislation and administrative practice, it analyses how the presence or absence of data, namely scientific evidence, interacts with pregnant people’s legal autonomy in healthcare. Data –particularly scientific evidence - is shown as something that is not neutral but open to interpretation and misappropriation. First, administrative complaints illustrate that not only a lack of scientific studies on pregnant people but also patriarchal attitudes have implications for care. Second, Scandinavian legislation authorizes the involuntary detention of pregnant drug users despite an absence of evidence supporting such drastic actions. Third, complaints bodies are found to frame injury to pregnant bodies as a natural consequence of birth, despite clear evidence as to the duties of healthcare professionals in preventing harm. A relational approach that sees the pregnant body and fetus as integrated though quintessentially unequal is needed. Evidence is not the only answer; an approach that recognizes the dignity of pregnant people must be central. This requires eliminating coercion, recognizing the pregnant patient as the decision maker in healthcare choices and prizing the birthing patient’s voice as a valuable data source.

An evaluation of the quality, suitability and impact on equity of clinical practice guidelines relevant to preterm birth for use in Aotearoa New Zealand

BackgroundPreterm birth is a leading cause of perinatal morbidity and mortality and a defining event for pregnant people, infants, and whānau (extended families). Recommendations have been made for a national preterm birth prevention initiative focusing on equity in Aotearoa New Zealand, including the development of a national best practice guide. An understanding of the number and quality of guidelines, and consideration of their suitability and impact on equity is required.MethodsGuidelines were identified through a systematic literature search, search of professional bodies websites, and invitation to regional health services in Aotearoa New Zealand. Obstetric and midwifery clinical directors were invited to report on guideline use. Identified guidelines were appraised by a 23-member trans-disciplinary Review Panel; quantitatively using the AGREE-II instrument and qualitatively using modified ADAPTE questions. The quality of guidelines available but not in use was compared against those in current use, and by health services by level of maternity and neonatal care. Major themes affecting implementation and impact on equity were identified using Braun and Clarke methodology.ResultsA total of 235 guidelines were included for appraisal. Guidelines available but not in use by regional health services scored higher in quality than guidelines in current use (median domain score Rigour and Development 47.5 versus 18.8, p < 0.001, median domain score Overall Assessment 62.5 versus 44.4, p < 0.001). Guidelines in use by regional health services with tertiary maternity and neonatal services had higher median AGREE II scores in several domains, than those with secondary level services (median domain score Overall Assessment 50.0 versus 37.5, p < 0.001). Groups identified by the Review Panel as experiencing the greatest constraints and limitations to guideline implementation were rural, provincial, low socioeconomic, Māori, and Pacific populations. Identified themes to improve equity included a targeted approach to groups experiencing the least advantage; a culturally considered approach; nationally consistent guidance; and improved funding to support implementation of guideline recommendations.ConclusionsWe have systematically identified and assessed guidelines on preterm birth. High-quality guidelines will inform a national best practice guide for use in Taonga Tuku Iho, a knowledge translation project for equity in preterm birth care and outcomes in Aotearoa.

Effective methods for engaging with YOPI (Young, Old, Pregnant, Immunocompromised) on food safety matters

Young, older, pregnant, and immunocompromised (YOPI) people are most vulnerable to foodborne illnesses due to impaired or underdeveloped immune systems(1). There is a lack of information regarding how YOPI groups access, receive or use information about food safety, what influences their food safety behaviour, and their preferences for receiving food safety advice. The objective of this research was to develop a better understanding of how YOPI consumers in New Zealand access and use food safety information, the types and sources of food safety information used, how information and advice are obtained, and how these influence their decision-making about food safety practices and related behaviours. Research questions were guided by a rapid review of literature. Twenty qualitative focus groups (comprising of either young, old, pregnant, or immunocompromised individuals) based in one of three locations in New Zealand were conducted. This was complemented with data from health care providers from relevant sectors (nutritionists, dietitians, aged care providers, cancer nurses, Well Child Tamariki Ora providers, and midwives). Recruitment included a focus on ethnic groups (Māori and Pasifika) to ensure diversity of experiences and perspectives were represented in the research and to reflect NZFS’s interest in developing fit-for-purpose messages and resources for these YOPI populations. Thematic and segmentation analysis was conducted to understand current food safety behaviours and how to best communicate food safety matters. Typologies of participants were developed by grouping participants based on common features: attitudes, beliefs, and experiences. The research revealed most participants are comfortable with their food safety practices and reported habitual behaviours. Many YOPI did not perceive themselves to be at a greater risk of foodborne illness, particularly older people. A key finding was that access to information does not necessarily lead to behaviour change. Groups undergoing periods of change (immunocompromised, pregnant and young) were more likely to seek additional information. Families and health professionals are trusted sources of information, with all groups reporting some use of the internet as an information source. An individual’s risk perception was the main motivating factor for obtaining and following advice. Habit, cost of food, and lack of information were key barriers to obtaining or acting on information, along with pregnant people reporting social pressures as a reason to not obtain or act on relevant advice. In general, there are three key types of food-safety messaging all groups would like to receive: situation-specific advice; information received alongside other key information (e.g., starting solids); and general information for the whole population. Gaining insights into YOPI preferences on food safety matters can aid the development of appropriate communication and engagement methods of the risks and impacts of food safety matters to vulnerable people.

Practical Considerations for Managing Pregnancy in Patients With Multiple Sclerosis: Dispelling the Myths.

Lack of consistent data and guidance have led to variations between clinicians in the management of pregnancy in women with multiple sclerosis (MS). Pregnant and/or lactating women are often excluded from clinical trials conducted in MS, and thus, the labeling for most disease-modifying therapies (DMTs) excludes use during pregnancy. This has led to heterogeneity in interpretation and labeling regarding the safety of DMTs during pregnancy and lactation and the required preconception washout periods. This review identifies key themes where there is conflicting information surrounding family planning and pregnancy in MS, focusing on the most common discussion points between physicians and patients during preconception planning, pregnancy, postpartum, and lactation. The goal was to inform the patient-physician conversation and provide best practice recommendations based on expert clinical expertise and experience. We outline the latest evidence-based data for DMT use during pregnancy and lactation, the effect of MS on fertility and fertility treatments, the risk of adverse pregnancy and delivery outcomes, the risk of postpartum relapse, and immunization and clinical imaging safety during pregnancy and breastfeeding. Management of family planning and pregnancy in patients with MS requires the most current information. Health care providers should discuss family planning early and frequently with patients with MS, and partners where practicable. Because management of pregnant people with MS will often require a risk/benefit analysis of their needs, shared decision-making in family planning discussions is emphasized. Additional data are needed for specific and underrepresented populations with MS (e.g., single parents or those from the LGBTQ+ community) and those at risk of racial and socioeconomic disparities in care. Pregnancy registries and the design and conduct of clinical trials focused on pregnant and lactating patients should provide additional data to guide the ongoing management of patients with MS.

Biological Testing and Interpretation of Laboratory Results Associated with Detecting Newborns with Substance Exposure.

Substance use during pregnancy is common, as is biological testing that is intended to help identify prenatal exposures. However, there is no standardized requirement for biological testing with either maternal or newborn specimens, nor is there standardization related to when testing occurs, how frequently testing occurs, what specimen(s) to test, what substances to test for, or how to perform testing. We review common specimen types tested to detect maternal and newborn substance exposure with a focus on urine, meconium, and umbilical cord tissue. We also review common analytical methods used to perform testing, including immunoassay, and mass spectrometry platforms. Considerations regarding the utilization of testing relative to the purpose of testing, the drug analyte(s) of interest, the specific testing employed, and the interpretation of results are emphasized to help guide decisions about clinical utilization of testing. We also highlight specific examples of unexpected results that can be used to guide interpretation and appropriate next steps. There are strengths and limitations associated with all approaches to detecting substance exposure in pregnant persons as well as biological testing to evaluate a newborn with possible substance exposure. Standardization is needed to better inform decisions surrounding evaluation of substance exposures in pregnant people and newborns. If biological sampling is pursued, testing options and results must be reviewed in clinical context, acknowledging that false-positive and -negative results can and do occur.

Physical activity among pregnant inpatients and outpatients and associations with anxiety

ObjectivePhysical activity is linked to lower anxiety, but little is known about the association during pregnancy. This is especially important for antepartum inpatients, who are known to have increased anxiety yet may not be able to achieve target levels of physical activity during hospitalization. We compared physical activity metrics between pregnant inpatients and outpatients and explored correlations with anxiety. Materials and MethodsThis was a prospective cohort between 2021 and 2022 of pregnant people aged 18–55 years carrying singleton gestations ≥ 16 weeks. Three exposure groups were matched for gestational age: 1) outpatients from general obstetric clinics; 2) outpatients from high-risk Maternal-Fetal Medicine obstetric clinics; and 3) antepartum inpatients. Participants wore Actigraph GT9X Link accelerometer watches for up to 7 days to measure physical activity. The primary outcome was mean daily step count. Secondary outcomes were metabolic equivalent tasks (METs), hourly kilocalories (kcals), moderate to vigorous physical activity (MVPA) bursts, and anxiety (State-Trait Anxiety Inventory [STAI]). Step counts were compared using multivariable generalized estimating equations adjusting for maternal age, body-mass index, and insurance type as a socioeconomic construct, accounting for within-group clustering by gestational age. Spearman correlations were used to correlate anxiety scores with step counts. Results58 participants were analyzed. Compared to outpatients, inpatients had significantly lower mean daily steps (primary outcome, adjusted beta −2185, 95 % confidence interval [CI] −3146, −1224, p < 0.01), METs (adjusted beta −0.18, 95 % CI −0.23, −0.13, p < 0.01), MVPAs (adjusted beta −38.2, 95 % CI −52.3, −24.1, p < 0.01), and kcals (adjusted beta –222.9, 95 % CI −438.0, −7.8, p = 0.04). Over the course of the week, steps progressively decreased for inpatients (p-interaction 0.01) but not for either of the outpatient groups. Among the entire cohort, lower step counts correlated with higher anxiety scores (r = 0.30, p = 0.02). ConclusionWe present antenatal population norms and variance for step counts, metabolic equivalent tasks, moderate to vigorous physical activity bursts, and kcals, as well as correlations with anxiety. Antepartum inpatients had significantly lower physical activity than outpatients, and lower step counts correlated with higher anxiety levels. These results highlight the need for physical activity interventions, particularly for hospitalized pregnant people.

Social Determinants Associated with Substance Use and Treatment Seeking in Females of Reproductive Age in the United States.

Introduction: Females of reproductive age (FoRA; 15-49 years) are the demographic most likely to be diagnosed with a substance use disorder. Preventative treatment prior to or during pregnancy is critical. Stigma and social inequities can delay access to care. There is limited research examining social determinants of health (SDoH) and how they are related to substance use and treatment seeking in this demographic. Methods: We analyzed the 2016-2019 data from the United States National Survey on Drug Use and Health using multivariable logistic regression models. Statistically significant variables were conceptually linked to the Office of Disease Prevention and Health Promotion's (ODPHP's) SDoH framework's five domains. Results: From a total sample of 1,477,336 (weighted) pregnant people and 39,600,523 (weighted) FoRA, substance use was reported by 879,209 (2.14% [95% confidence interval = 2.13-2.15]). Pregnancy status was not associated with substance use or treatment seeking. Past-month substance use was associated with high educational attainment, an annual income <$20,000, a history of criminality, low religiosity, and having health insurance. Past-month treatment-seeking behavior was associated with older age, an annual income >$20,000, a history of criminality, and greater religiosity. Behavioral health support seeking in the past month was associated with some college education. Higher depression severity was associated with all the three models. Conclusions: Using the ODPHP's SDoH framework, we begin to elicit critical connections that can describe substance use and treatment-seeking practices in FoRA. We encourage additional research to inform public health, health care, behavioral health, and other support service programming.

Risk factors related to the SARS-CoV-2 vaccine additional doses hesitancy among pregnant and non-pregnant people of reproductive age and partners: A Brazilian cross-sectional study.

The aim of this study was to assess the predictors of acceptance and hesitancy of additional doses of any SARS-CoV-2 (COVID-19) vaccine among pregnant or recently pregnant and non-pregnant people of reproductive age and partners in Brazil. We conducted an online cross-sectional study from June 2022 to April 2023 and invited women and partners between 18 and 49 years old to participate. We employed a snowball strategy to reach all potential eligible participants. Our primary outcome was the acceptance rate of the COVID-19 booster vaccine. We estimated the frequency and percentage for the three groups and compared categorical variables using the Chi-square test. Moreover, bivariate, backward stepwise regression, and subgroup analyses were performed to evaluate risk factors and predictors of COVID-19 vaccine booster hesitancy. We reported the effect size as OR with a 95% CI. We included 1487 participants, and among them, 334 (22.5%) were pregnant or recently pregnant people, 905 (60.8%) were non-pregnant people, and 247 (16.6%) were male partners. Pregnant and recently pregnant people showed greater hesitancy for the COVID-19 vaccine booster than non-pregnant people (28% vs 15%, P < 0.001) and male partners (28% vs 16%, P < 0.001). Non-pregnant women accepted the COVID-19 vaccine more often than pregnant or recently pregnant people (OR 1.75; 95% CI: 1.13-2.70). The associated factors to the reduced COVID-19 vaccine booster acceptance were family income between US$ 566-945.00 (54%), evangelic religion (65%), concern about vaccine safety (80%) and perceived common vaccine importance (93%). Pregnant people were more hesitant than non-pregnant people to accept the COVID-19 booster vaccine. Family income, religious beliefs, vaccine safety concerns, and perceived common vaccine importance were significant barriers to accepting COVID-19 booster vaccines. The impact of these factors was more evident among pregnant or recently pregnant people, emphasizing the harmful effect of misinformation among this vulnerable population.

A clinical trial protocol of a single-session self-guided acceptance-based online intervention targeting food cravings as predictors of disordered eating in pregnant people

BackgroundPregnancy is a time of heightened risk for disordered eating behaviors, which are linked to adverse health outcomes in gestation, delivery, and the postpartum. These adverse outcomes may be partially mediated by greater rates of deviation from recommended weight gain trajectories, especially in those who engage in binge and loss of control (LOC) eating. Food cravings are powerful and highly modifiable triggers of binge and LOC eating in non-pregnant populations with preliminary evidence linking cravings to disordered eating behaviors in pregnancy as well. Acceptance-based approaches have been shown to be feasible and effective in reducing the adverse impact of cravings on behavior. PurposeTo test the feasibility, acceptability, and preliminary efficacy of a single-session, self-guided, acceptance-based online workshop targeting food cravings as predictors of binge and LOC eating in pregnancy. MethodsWe will conduct a pilot randomized controlled trial of a single-session, self-guided online acceptance-based workshop targeting food cravings in pregnancy. Pregnant individuals in the second trimester (n ≥ 74) endorsing current food cravings will be randomly assigned to the intervention or an untreated control group. The intervention group will participate in a one-hour workshop that imparts skills grounded in Acceptance and Commitment Therapy, including acceptance, defusion, and present-moment awareness. Both groups will complete comprehensive self-report assessments of primary outcomes and hypothesized mediators and moderators of intervention efficacy at baseline, one-month follow-up, and at full-term. ConclusionResults will inform integration of acceptance-based skills targeting food cravings into routine prenatal care to prevent adverse outcomes associated with disordered eating behaviors in pregnancy.Trial registration: ClinicalTrials.gov identifier NCT06129461; registered on November 10, 2023.
