Early postpartum blood pressure screening is associated with increased detection of cardiovascular risk factors in women with hypertensive disorders of pregnancy.

BACKGROUND: Hypertensive disorders of pregnancy (HDP), including gestational hypertension, preeclampsia, and eclampsia, are risk factors for cardiovascular (CV) disease. Guidelines recommend that women with HDP be screened for the development of hypertension (HTN) within 6-12 months postpartum. However, the extent to which this early blood pressure (BP) screening is being performed and the impact on detection of CV risk factors is unknown. METHODS: Women with HDP and without pre-existing hypertension (HTN) who had at least 6 months of clinical follow-up were categorized by postpartum BP screening status: early BP screen (6-12 months after delivery) or late BP screen (≥12 months after delivery). Multivariable logistic regression identified factors associated with early screening. Multivariable Cox proportional hazards modeling examined the association between early screening and detection of incident CV risk factors: HTN, prediabetes, diabetes mellitus type 2, or hyperlipidemia. RESULTS: Among 4194 women with HDP, 1172 (28%) received early BP screening. Older age, pre-existing hyperlipidemia, diabetes, sickle cell disease, hypothyroidism, gestational diabetes, and delivery during or after 2014 were independently associated with early BP screening, whereas Hispanic ethnicity was associated with late BP screening. Early BP screening was most commonly performed at a primary care visit. After a median follow-up of 3.7 years, 1012 (24%) women had at least 1 new risk factor detected. Even after adjustment for baseline risk, women receiving early BP screening had a significantly higher rate of incident CV risk factor detection than women receiving late BP screening (56% vs 28%; adj. HR 2.70, 95%CI: 2.33-3.23, P < .001). CONCLUSIONS: Early postpartum BP screening was performed in a minority of women with HDP, but was associated with greater detection of CV risk factors. More intensive postpartum CV screening and targeted interventions are needed to optimize CV health in this high-risk population of women with HDP.

Time to pregnancy recognition among users of an FDA-cleared fertility application.

Background: Previous investigations of time-to-pregnancy recognition have analysed data from national surveys and clinics, but this has not been investigated in the context of digital fertility applications. Timely pregnancy recognition can help individuals in health and pregnancy management, reducing maternal and foetal risk and costs, whilst increasing treatment options, availability, and cost. Methods: This dataset contained 23,728 pregnancies (conceived between June 2018 and December 2022) from 20,429 participants using a Food and Drug Administration (FDA) cleared fertility app in the United States. Most participants (with non-missing information) identified as Non-Hispanic White, and one-third reported obtaining a university degree. We used two-tailed Welch's t-test, Mann-Whitney U-test, and two-tailed Z-tests to compare time to pregnancy recognition between those using the app to conceive or contracept. Results: Participants using an app to conceive recognised pregnancy on average at 31.3 days from last menstrual period (LMP) compared to 35.9 days among those using the app to prevent pregnancy. Conclusion: Generalisability is limited, as all participants were using a fertility app and had relatively homogenous sociodemographic characteristics.

People who recognise pregnancy early may benefit, as earlier recognition can reduce costs and risks, and make more treatment options available. In the past, researchers have studied the time it takes for an individual to recognise that they are pregnant by asking them in national surveys or when they attend a clinic. However, with the advent of digital fertility tracking apps, we investigated the time it takes to recognise pregnancy when using such an app. We analysed data from 23,728 pregnancies from 20,429 users of the Natural Cycles app between June 2018 and December 2022. We found that participants using the app to try to get pregnant recognised pregnancy an average of 4.6 days earlier than those using the app to prevent pregnancy.

Understanding the perspective of women who use the Billings Ovulation Method®: a focus group study.

BACKGROUND: The Billings Ovulation Method®(the Billings Method) is a fertility awareness-based method (FABM) of family planning that relies on the observation of patterns of fertility and infertility based on vulvar sensations and appearance of discharges. This allows people to choose when to have intercourse, depending on whether they want to avoid or achieve pregnancy. Few studies have documented user experiences with FABMs. METHODS: We conducted four virtual focus groups (FGs) in May and June 2021 with current adult women users of the Billings Method. We asked questions about users' reasons for selecting a FABM and the Billings Method, positive experiences and challenges learning and using the Billings Method, and suggestions for improving the user experience. We performed a content analysis of the transcribed FGs to explore key themes from the discussions. COREQ guidelines were followed. RESULTS: Twenty women between the ages of 23 and 43 participated in the FGs. Reasons women described choosing a FABM included to follow religious beliefs, to avoid side effects of hormonal contraception, and/or to learn more about their bodies. Reasons for selecting the Billings Method included perceiving it as more precise and easier to understand than other FABMs, having a scientific basis, and being recommended by family and friends. Experiences related to learning and using the Billings Method were mainly positive. They included finding the method easy to use and learn, successfully using it to either postpone or achieve a pregnancy and increasing their awareness of their bodies. Challenges for participants included the inherent learning curve for identifying sensations at the vulva and the required periods of abstinence. Participants provided suggestions and recommendations for improving users' experience, including raising awareness of the Billings Method among healthcare providers. CONCLUSIONS: Users of the Billings Method expressed an overall positive experience when learning and using it for family planning and body awareness. Some challenges were identified that offer opportunities to improve how the Billings Method is taught and delivered. These findings can also enhance healthcare providers' interactions with FABM users, including those of the Billings Method.

Folic Acid Supplementation to Prevent Neural Tube Defects: Updated Evidence Report and Systematic Review for the US Preventive Services Task Force.

Importance: Neural tube defects are among the most common birth defects in the US. Objective: To review new evidence on the benefits and harms of folic acid supplementation for the prevention of neural tube defects to inform the US Preventive Services Task Force. Evidence Review: Sources included PubMed, Cochrane Library, Embase, and trial registries from July 1, 2015, through July 2, 2021; references; and experts, with surveillance through February 10, 2023. Two investigators independently reviewed English-language randomized studies and nonrandomized cohort studies in very highly developed countries that focused on the use of folic acid supplementation for the prevention of neural tube defect-affected pregnancies; methodological quality was dually and independently assessed. Findings: Twelve observational studies (reported in 13 publications) were eligible for this limited update (N = 1 244 072). Of these, 3 studies (n = 990 372) reported on the effect of folic acid supplementation on neural tube defects. For harms, 9 studies were eligible: 1 randomized clinical trial (n = 431) reported on variations in twin delivery, 7 observational studies (n = 761 125) reported on the incidence of autism spectrum disorder, and 1 observational study (n = 429 004) reported on maternal cancer. Two cohort studies and 1 case-control study newly identified in this update reported on the association between folic acid supplementation and neural tube defects (n = 990 372). One cohort study reported a statistically significant reduced risk of neural tube defects associated with folic acid supplementation taken before pregnancy (adjusted relative risk [aRR], 0.54 [95% CI, 0.31-0.91]), during pregnancy (aRR, 0.62 [95% CI, 0.39-0.97]), and before and during pregnancy (aRR, 0.49 [95% CI, 0.29-0.83]), but this association occurred for only the later of 2 periods studied (2006-2013 and not 1999-2005). No other statistically significant benefits were reported overall. No study reported statistically significant harms (multiple gestation, autism, and maternal cancer) associated with pregnancy-related folic acid exposure. Conclusions and Relevance: New evidence from observational studies provided additional evidence of the benefit of folic acid supplementation for preventing neural tube defects and no evidence of harms related to multiple gestation, autism, or maternal cancer. The new evidence was consistent with previously reviewed evidence on benefits and harms.

Screening for Bacterial Vaginosis in Pregnant Adolescents and Women to Prevent Preterm Delivery: Updated Evidence Report and Systematic Review for the US Preventive Services Task Force.

Importance: Preterm delivery results in adverse outcomes; identifying and treating bacterial vaginosis may reduce its occurrence. Objective: To update the evidence on screening and treatment of asymptomatic bacterial vaginosis in pregnancy for the US Preventive Services Task Force. Data Sources: MEDLINE, Cochrane Library, and trial registries through May 29, 2019; bibliographies from retrieved articles, experts, and surveillance of the literature through December 31, 2019. Study Selection: Fair- or good-quality English-language studies evaluating diagnostic accuracy of tests feasible within primary care; randomized clinical trials (RCTs); nonrandomized controlled intervention studies (for harms only); or meta-analyses of metronidazole or clindamycin. Data Extraction and Synthesis: Two reviewers independently assessed titles/abstracts and full-text articles, extracted data, and assessed study quality; when at least 3 similar studies were available, meta-analyses were conducted. Main Outcomes and Measures: Sensitivity, specificity, preterm delivery, maternal adverse effects, congenital birth defects, childhood cancer. Results: Forty-four studies (48 publications) were included. No studies evaluated the benefits or harms of screening. Twenty-five studies (n = 15 785) evaluated the accuracy of screening tests; across individual studies and tests, sensitivity ranged from 0.36 to 1.0 and specificity ranged from 0.49 to 1.0. Among trials reporting findings from general obstetric populations (n = 7953), no significant association was observed between treatment and spontaneous delivery before 37 weeks (pooled absolute risk difference [ARD], -1.44% [95% CI, -3.31% to 0.43%]; 8 RCTs, n = 7571) or any delivery before 37 weeks (pooled ARD, 0.20% [95% CI, -1.13% to 1.53%]; 6 RCTs, n = 6307). Among 5 trials reporting findings among women with a prior preterm delivery, findings were inconsistent; 3 showed a significant beneficial effect, while 2 did not. Maternal adverse events from treatment were infrequent and minor (eg, candidiasis) but were slightly more common with active treatment compared with placebo across 8 RCTs. Two meta-analyses of observational studies reported no significant association between metronidazole exposure and congenital malformations (odds ratio, 0.96 [95% CI, 0.75 to 1.22]; odds ratio, 1.08 [95% CI, 0.90 to 1.29]). One cohort study reported no significantly increased incidence of childhood cancer among metronidazole-exposed children (adjusted relative risk, 0.81 [95% CI, 0.41 to 1.59]). However, studies of in utero exposure had important limitations. Conclusions and Relevance: Accuracy of screening tests for bacterial vaginosis varies. The evidence suggests no difference in the incidence of preterm delivery and related outcomes from treatment for asymptomatic bacterial vaginosis in a general obstetric population but was inconclusive for women with a prior preterm delivery. Maternal adverse events from treatment appear to be infrequent and minor, but the evidence about harms from in utero exposure was inconclusive.

Risk of Diabetes After Hysterectomy With or Without Oophorectomy in Postmenopausal Women.

The aim of this study was to determine the associations between hysterectomy, bilateral salpingo-oophorectomy (BSO), and incidence of diabetes in postmenopausal women participating in the Women's Health Initiative (WHI), a series of trials conducted in the United States, during the period 1993-1998. A total of 67,130 postmenopausal women aged 50-79 years were followed for a mean of 13.4 years. Among them, 7,430 cases of diabetes were diagnosed. Multivariable Cox proportional hazards models were used to assess the association between hysterectomy/oophorectomy status and diabetes incidence. Compared with women without hysterectomy, women with hysterectomy had a significantly higher risk of diabetes (hazard ratio = 1.13, 95% confidence interval: 1.06, 1.21). The increased risk of diabetes was similar for women with hysterectomy only and for women with hysterectomy with concomitant BSO. Compared with hysterectomy alone, hysterectomy with BSO was not associated with additional risk of diabetes after stratification by age at hysterectomy and hormone therapy status. In our large, prospective study, we observed that hysterectomy, regardless of oophorectomy status, was associated with increased risk of diabetes among postmenopausal women. However, our data did not support the hypothesis that early loss of ovarian estrogens is a risk factor for type 2 diabetes. The modest increased risk of diabetes associated with hysterectomy may be due to residual confounding, such as the reasons for hysterectomy.

Evaluation of diet pattern and weight gain in postmenopausal women enrolled in the Women's Health Initiative Observational Study.

It is unclear which of four popular contemporary diet patterns is best for weight maintenance among postmenopausal women. Four dietary patterns were characterised among postmenopausal women aged 49-81 years (mean 63·6 (sd 7·4) years) from the Women's Health Initiative Observational Study: (1) a low-fat diet; (2) a reduced-carbohydrate diet; (3) a Mediterranean-style (Med) diet; and (4) a diet consistent with the US Department of Agriculture's Dietary Guidelines for Americans (DGA). Discrete-time hazards models were used to compare the risk of weight gain (≥10 %) among high adherers of each diet pattern. In adjusted models, the reduced-carbohydrate diet was inversely related to weight gain (OR 0·71; 95 % CI 0·66, 0·76), whereas the low-fat (OR 1·43; 95 % CI 1·33, 1·54) and DGA (OR 1·24; 95 % CI 1·15, 1·33) diets were associated with increased risk of weight gain. By baseline weight status, the reduced-carbohydrate diet was inversely related to weight gain among women who were normal weight (OR 0·72; 95 % CI 0·63, 0·81), overweight (OR 0·67; 95 % CI 0·59, 0·76) or obese class I (OR 0·63; 95 % CI 0·53, 0·76) at baseline. The low-fat diet was associated with increased risk of weight gain in women who were normal weight (OR 1·28; 95 % CI 1·13, 1·46), overweight (OR 1·60; 95 % CI 1·40, 1·83), obese class I (OR 1·73; 95 % CI 1·43, 2·09) or obese class II (OR 1·44; 95 % CI 1·08, 1·92) at baseline. These findings suggest that a low-fat diet may promote weight gain, whereas a reduced-carbohydrate diet may decrease risk of postmenopausal weight gain.

"We Know but We Don't Really Know": Diet, Physical Activity and Cardiovascular Disease Prevention Knowledge and Beliefs Among Underserved Pregnant Women.

To describe the knowledge of underserved pregnant women related to diet, physical activity, and cardiovascular disease (CVD). Underserved pregnant women from the University of North Carolina and Pitt County, North Carolina participated in 9 focus group interviews. Focus group questions focused on knowledge of CVD risk factors, lifestyle prevention strategies such as diet and physical activity, and the sources of such knowledge. Data were analyzed with the constant comparative method. Prior to the focus group, each woman was invited to complete a telephone survey to collect demographic information and responses to a 13-item CVD knowledge questionnaire. Means and frequency procedures were used to analyze demographic information. Fifty women participated in nine focus group interviews. Participants possessed basic knowledge of CVD risk factors and preventive strategies, such as basic guidelines and recommendations for healthy diet and physical activity in pregnancy. However, women often receive incomplete guidance from obstetric providers, and women, therefore, desired more information on these topics. Some gaps were filled by nurses and nutritionists. Women also sought information from female friends and relatives. Incorrect knowledge was demonstrated in all groups and led to less healthful behaviors in some cases. Underserved pregnant women have basic knowledge about healthy lifestyle and CVD prevention behaviors; however important gaps and misinformation exist.

Systematic review of the effect of individual and combined nutrition and exercise interventions on weight, adiposity and metabolic outcomes after delivery: evidence for developing behavioral guidelines for post-partum weight control.

BACKGROUND: Post-partum weight retention contributes to the risk of chronic obesity and metabolic alterations. We conducted a systematic review of randomized controlled trials (RCTs) on the effect of post-partum nutrition and exercise interventions on weight loss and metabolic outcomes. DATA SOURCES: Four electronic databases were searched from inception to January, 2012. Two investigators reviewed titles and abstracts, performed data abstraction on full articles and assessed study quality. METHODS: We included RCTs comparing nutrition, exercise or combined nutrition and exercise interventions with a control condition. Thirteen studies met our inclusion criteria (N = 1,310 participants). Data were abstracted on study characteristics, intervention components, enrollment period, and length of follow-up. Outcomes of interest included weight, adiposity, cardio-metabolic measures (glucose, lipids) and obesity-related inflammatory markers. RESULTS: Nine trials compared combined interventions to standard post-partum care; three trials assessed the effect of exercise interventions, one trial evaluated a nutrition-only intervention. Four good quality RCTs on combined interventions had inconsistent findings, with the larger RCT (N = 450) reporting no difference in weight between groups. Four fair-to good quality RCTs reported greater weight loss in the combined intervention group vs. standard care, ranging from 0.17 kg to 4.9 kg. Results from exercise only interventions were inconclusive. Evidence for nutrition only interventions was insufficient. There was insufficient evidence for the effect of post-partum interventions on metabolic risk factors and inflammatory biomarkers. CONCLUSIONS: Combined nutrition and exercise interventions can achieve weight loss, but evidence is limited due to a small number of trials and limitations in study design.

Antihypertensive medication use during pregnancy in a real-world cohort of patients diagnosed with a hypertensive disorder of pregnancy.

Hypertensive disorders of pregnancy (HDP) are rising in prevalence and associated with adverse maternal and infant health outcomes. Current guidelines recommend labetalol, nifedipine, and methyldopa as acceptable first-line agents to treat HDP in outpatient settings. However, the current practice regarding antihypertensive medication usage and selection remain unclear. A retrospective, observational cohort study was conducted in 1,641 patients with a physician diagnosis of HDP who delivered at two academic medical centers in North Carolina from 2014 to 2017. Use of any antihypertensive medication, and the agent selected, at any encounter during pregnancy or on the delivery date was collected from the electronic health record. Proportions were compared across HDP diagnosis (eclampsia/severe preeclampsia, chronic hypertension with superimposed preeclampsia, preeclampsia, gestational hypertension) by Chi-square tests and multivariable logistic regression. Antihypertensive medications were used in 1,276 (77.8%) patients overall. Among treated patients, labetalol (74.9%) was the most frequently used medication followed by nifedipine (29.6%) and hydralazine (20.5%). Methyldopa was used infrequently (4.4%). HDP type was the strongest factor associated with use of an antihypertensive agent. Relative to gestational hypertension, antihypertensive use was significantly more likely [odds ratio (95% CI)] in patients with severe preeclampsia [5.94 (3.85-9.16)], chronic hypertension with superimposed preeclampsia [4.99 (3.46-7.19)], and preeclampsia [2.13 (1.61-2.82)]. In a real-world setting, antihypertensive medication use among HDP patients was common, labetalol, nifedipine, and hydralazine were the most commonly selected agents, and increasing HDP severity was associated with a higher likelihood of antihypertensive use. Future studies comparing medication effectiveness in pregnant patients with distinct HDP diagnoses are needed.

Pregnancy and Emergency Department Utilization in North Carolina, 2016-2021: A Population-Based Surveillance Study.

Introduction: Pregnancy-associated complaints are a common reason for emergency department visits for women of reproductive age. Emergency department utilization during pregnancy is associated with worse birth outcomes for both mothers and infants. We used statewide North Carolina emergency department surveillance data between 2016 and 2021 to describe the sociodemographic factors associated with the use of emergency department for pregnancy-associated problems and subsequent hospital admission. Methods: North Carolina Disease Event Tracking and Epidemiologic Collection Tool is a syndromic surveillance system that includes all emergency department encounters at civilian acute-care facilities in North Carolina. We analyzed all emergency department visits between January 1, 2016 and December 31, 2021 for female patients aged 15-44 years residing in North Carolina with at least 1 ICD-10-CM code (analysis occurred in July 2021-October 2022). Each emergency department visit was categorized as pregnancy-associated if assigned ICD-10-CM code(s) indicated pregnancy. We stratified visits by age, race, ethnicity, county of residence, and insurance and compared them with estimated pregnant population proportions using 1-sample t-tests. We used multivariable logistic regression to determine whether pregnancy-associated visits were more likely to be associated with hospital admission and then to determine sociodemographic predictors of admission among pregnancy-associated emergency department visits. Results: More than 6.4 million emergency department visits were included (N=6,471,197); 10.1% (n=655,476) were pregnancy-associated, significantly higher than the proportion of women estimated to be pregnant at any given time in North Carolina (4.6%, p<0.0001) and increased over time (8.6% in 2016 vs 11.1% in 2021, p<0.0001). Pregnancy-associated visits were lower than expected for ages 25-44 years and higher than expected for those aged 15-24 years, for those of Black race, and for patients residing in rural or suburban areas. The proportion admitted was higher for pregnancy-associated emergency department visits than for nonpregnancy associated (15.6% vs 7.0%, AOR=3.06 [95% CI=3.03, 3.09]). Pregnancy-associated emergency department visits for patients of Black race had 0.58 times (95% CI=0.57, 0.59) the odds of admission compared with White patients. Conclusions: Emergency department utilization during pregnancy is common. The proportion of pregnancy-associated emergency department visits among reproductive-age women is increasing, as are inpatient admissions from the emergency department for pregnancy-associated diagnoses. Use of public health surveillance databases such as the North Carolina Disease Event Tracking and Epidemiologic Collection Tool may help identify opportunities for improving disparities in maternal health care, especially related to access to care.

Racial and Ethnic Differences in Self-Reported COVID-19 Exposure Risks, Concerns, and Behaviors Among Diverse Participants in the Women's Health Initiative Study.

BACKGROUND: Racial and ethnic disparities in coronavirus disease 2019 (COVID-19) risk are well-documented; however, few studies in older adults have examined multiple factors related to COVID-19 exposure, concerns, and behaviors or conducted race- and ethnicity-stratified analyses. The Women's Health Initiative (WHI) provides a unique opportunity to address those gaps. METHODS: We conducted a secondary analysis of WHI data from a supplemental survey of 48 492 older adults (mean age 84 years). In multivariable-adjusted modified Poisson regression analyses, we examined predisposing factors and COVID-19 exposure risk, concerns, and behaviors. We hypothesized that women from minoritized racial or ethnic groups, compared to non-Hispanic White women, would be more likely to report: exposure to COVID-19, a family or friend dying from COVID-19, difficulty getting routine medical care or deciding to forego care to avoid COVID-19 exposure, and having concerns about the COVID-19 pandemic. RESULTS: Asian women and non-Hispanic Black/African American women had a higher risk of being somewhat/very concerned about risk of getting COVID-19 compared to non-Hispanic White women and each was significantly more likely than non-Hispanic White women to report forgoing medical care to avoid COVID-19 exposure. However, Asian women were 35% less likely than non-Hispanic White women to report difficulty getting routine medical care since March 2020 (adjusted relative risk 0.65; 95% confidence interval 0.57, 0.75). CONCLUSIONS: We documented COVID-related racial and ethnic disparities in COVID-19 exposure risk, concerns, and care-related behaviors that disfavored minoritized racial and ethnic groups, particularly non-Hispanic Black/African American women.

Unmet health needs identified by Haitian women as priorities for attention: a qualitative study.

This 2009 qualitative study investigated Haitian women's most pressing health needs, barriers to meeting those needs and proposed solutions, and how they thought the community and outside organizations should be involved in addressing their needs. The impetus for the study was to get community input into the development of a Family Health Centre in Leogane, Haiti. Individual interviews and focus group discussions were conducted with 52 adult women in six communities surrounding Leogane. The most pressing health needs named by the women were accessible, available and affordable health care, potable water, enough food to eat, improved economy, employment, sanitation and education, including health education. Institutional corruption, lack of infrastructure and social organization, the cost of health care, distance from services and lack of transport as barriers to care were also important themes. The involvement of foreign organizations and local community groups, including grassroots women's groups who would work in the best interests of other women, were identified as the most effective solutions. Organizations seeking to improve women's health care in Haiti should develop services and interventions that prioritize community partnership and leadership, foster partnerships with government, and focus on public health needs.

Vitamin D in pregnancy: current concepts.

PURPOSE OF REVIEW: Vitamin D is part of a complex steroid hormone system long known to be involved in bone metabolism. Recently, vitamin D has been implicated in physiologic processes as diverse as vascular health, immune function, metabolism and placental function. This review summarizes the current evidence for the role of vitamin D in pregnancy and perinatal outcomes A systematic review of articles published in PubMed between May 2010 and October 2011 was undertaken using key words for vitamin D and pregnancy. Seventy-eight studies were reviewed. RECENT FINDINGS: The biologic evidence regarding a role for vitamin D in reproductive outcomes is strong, and rates of vitamin D deficiency may be high among pregnant women. However, no consensus exists regarding optimum vitamin D levels in pregnancy or standard measurement of vitamin D deficiency. Clinical studies establishing an association between vitamin D levels and adverse pregnancy outcomes such as preeclampsia, gestational diabetes, low birthweight, preterm labor, cesarean delivery and infectious diseases have conflicting results. This is likely due to a paucity of randomized trials, heterogeneity of populations studied and low sample size with poor adjustment for confounding among observational studies. SUMMARY: Further research should focus on defining optimum 25-hydroxy vitamin D levels in pregnancy as well as among various subgroups of the population. Randomized trials are needed to determine whether vitamin D supplementation can improve pregnancy outcomes. Currently, the American College of Obstetrics and Gynecology and the Institute of Medicine recommend 600 IU of daily vitamin D supplementation during pregnancy to support maternal and fetal bone metabolism.

Listening to patients: Opportunities to improve reproductive wellness for women with chronic conditions.

OBJECTIVE: To understand how Black and Native American women with chronic conditions experience reproductive health care and identify patient-centered strategies to improve care. STUDY SETTING AND PARTICIPANTS: We held a series of virtual focus groups between February 2021 and December 2021 with 34 women who self-identified as Black or Native American, were of childbearing age, had one or more chronic conditions, and lived in North Carolina. STUDY DESIGN AND ANALYSIS: This qualitative, community-engaged study reviewed notes, video recordings, and graphic illustrations from the focus group sessions. Content analysis was used to iteratively identify themes. Emerging themes were reviewed by community and patient partners. PRINCIPAL FINDINGS: There were six thematic areas that emerged on the current state of reproductive health care for people with chronic conditions: (1) lack of trust in health care providers and institutions, (2) lack of health care provider knowledge, (3) uncoordinated care, (4) need for self-advocacy, (5) provider bias, and (6) mental health strain from coping. Six approaches for care improvement emerged: (1) build on models of coordinated health care services from other conditions to design more comprehensive care clinics, (2) involve care coordinators or navigators, (3) improve educational materials for patients, (4) train clinicians to increase their capacity to be trustworthy and provide quality, equitable, person-focused care, (5) design scripts to improve clinicians' ability to talk with women about infertility, miscarriage, infant loss, and (6) all interventions and research should be co-designed to address patient priorities. CONCLUSIONS: Engaging Black and Native American patient partners with chronic conditions in research planning is feasible, necessary, and beneficial using methods that support connection, respect, and bi-directional learning. Patient partners defined actionable strategies to improve reproductive care and wellness including comprehensive care clinics with patient navigators, trust-enhancing interventions, and better provision of reproductive health related education.

Effectiveness of fertility awareness-based methods for pregnancy prevention during the postpartum period.

OBJECTIVES: To summarize the evidence on typical and perfect-use effectiveness of fertility awareness-based methods for avoiding pregnancy during the postpartum period, whether breastfeeding or not. STUDY DESIGN: We conducted a systematic review of studies published in English, Spanish, French, or German by November 2021 in MEDLINE, EMBASE, CINAHL, Web of Science, and ClinicalTrials.gov. Abstract and full text reviews were completed by 2 independent reviewers. Study inclusion: at least 50 subjects who enrolled prior to experiencing 3 cycles after childbirth and were using a specific fertility awareness-based method to avoid pregnancy; unintended pregnancy rate or probability calculated; postpartum amenorrheic and postpartum cycling individuals analyzed separately; and prospectively measured pregnancy intentions and outcomes. Outcomes were abstracted and study quality was systematically assessed by 2 independent investigators. RESULTS: Four studies provided effectiveness data for 1 specific fertility awareness-based method among postpartum individuals. Of these, there were zero high quality, 1 moderate quality, and 3 low quality for our question of interest. Typical-use pregnancy probability for the first 6 cycles postpartum for Marquette Method users was 12.0 per 100 women years (standard error [SE] not reported) and for Billings Ovulation Method users ranged from 9.1 (SE 3.9) for non-lactating women <30 years old to 26.8 (SE 4.6) for lactating women <30 years old. Typical-use pregnancy probabilities for the first 6 months post-first menses for the Postpartum Bridge to Standard Days Method users was 11.8 (95% confidence interval 6.01-17.16) and for Billings Ovulation Method users was 8.5 per 100 women (SE 1.7). CONCLUSION: The current evidence on the effectiveness of each fertility awareness-based method for postpartum persons is very limited and of mostly low quality. More high quality studies on the effectiveness of fertility awareness-based method in postpartum persons are needed to inform clinical counseling and patient-centered decision-making. IMPLICATIONS: Although postpartum individuals may desire to use fertility awareness-based methods to avoid pregnancy, the evidence of the effectiveness of fertility awareness-based methods in this population is limited. More high-quality studies are needed to inform shared decision-making.

Assessing Preconception Wellness in the Clinical Setting Using Electronic Health Data.

Background: One key strategy to reduce maternal morbidity and mortality involves optimizing prepregnancy health. Although nine core indicators of preconception wellness (PCW) have been proposed by clinical experts, few studies have attempted to assess the preconception health status of a population using these indicators. Methods: We conducted a retrospective chart review study of patients who received prenatal or primary care, identified by pregnancy-related ICD-10 codes, at either of two health systems in geographically and socioeconomically different areas of North Carolina between October 1, 2015, and September 30, 2018. Our primary study aim was to determine the feasibility of measuring the proposed PCW indicators through retrospective review of prenatal electronic health records at these two institutions. Results: Data were collected from 15,384 patients at Site 1 and 6,983 patients at Site 2. The indicators most likely to be documented and to meet the preconception health goal at each site were avoidance of teratogenic medications (98.8% and 98.3% at Sites 1 and 2, respectively) and entry to care in the first trimester (64.5% and 73.5% at Sites 1 and 2, respectively), whereas our measures of folic acid use, depression screening, and discussion of family planning were documented less than 20% of the time at both sites. Conclusions: Differences in measuring and documenting PCW indicators across the two health systems in our study presented barriers to monitoring and optimizing PCW. Efforts to address health and wellness before pregnancy will likely require health systems and payors to standardize, incorporate, and promote preconception health indicators that can be consistently measured and analyzed across health systems.

The Impact of Pregnancy on Antihypertensive Drug Metabolism and Pharmacokinetics: Current Status and Future Directions.

INTRODUCTION: Hypertensive disorders of pregnancy (HDP) are rising in prevalence, and increase risk of adverse maternal and fetal outcomes. Physiologic changes occur during pregnancy that alter drug pharmacokinetics. However, antihypertensive drugs lack pregnancy-specific dosing recommendations due to critical knowledge gaps surrounding the extent of gestational changes in antihypertensive drug pharmacokinetics and underlying mechanisms. AREAS COVERED: This review (1) summarizes currently recommended medications and dosing strategies for non-emergent HDP treatment, (2) reviews and synthesizes existing literature identified via a comprehensive PubMed search evaluating gestational changes in the maternal pharmacokinetics of commonly prescribed HDP drugs (notably labetalol and nifedipine), and (3) offers insight into the metabolism and clearance mechanisms underlying altered HDP drug pharmacokinetics during pregnancy. Remaining knowledge gaps and future research directions are summarized. EXPERT OPINION: A series of small pharmacokinetic studies illustrate higher oral clearance of labetalol and nifedipine during pregnancy. Pharmacokinetic modeling and preclinical studies suggest these effects are likely due to pregnancy-associated increases in hepatic UGT1A1- and CYP3A4-mediated first-pass metabolism and lower bioavailability. Accordingly, higher and/or more frequent doses may be needed to lower blood pressure during pregnancy. Future research is needed to address various evidence gaps and inform the development of more precise antihypertensive drug dosing strategies.

Community Health Worker Training Curricula and Intervention Outcomes in African American and Latinx Communities: A Systematic Review.

In recent years, community health workers (CHWs) have emerged as key stakeholders in implementing community-based public health interventions in racially diverse contexts. Yet little is known about the extent to which CHW training curriculums influence intervention effectiveness in marginalized racial and ethnic minority communities. This review summarizes evidence on the relationship between CHW training curricula and intervention outcomes conducted among African American and Latinx populations. We conducted a literature search of intervention studies that focused on CHW public health interventions in African American and Latinx populations using PubMed, PsycINFO, ERIC, CINAHL, EMBASE, and Web of Science databases. Included studies were quantitative, qualitative, and mixed methods studies employed to conduct outcome (e.g., blood pressure and HbA1c) and process evaluations (e.g., knowledge and self-efficacy) of CHW-led interventions. Out of 3,295 articles from the database search, 36 articles met our inclusion criteria. Overall, the strength of evidence linking specific CHW training curricula components to primary intervention health outcomes was weak, and no studies directly linked outcomes to specific characteristics of CHW training. Studies that described training related to didactic sessions or classified as high intensity reported higher percentages of positive outcomes compared to other CHW training features. These findings suggest that CHW training may positively influence intervention effectiveness but additional research using more robust methodological approaches is needed to clarify these relationships.

A Mixed-Methods Assessment of Health Care Providers' Knowledge, Attitudes, and Practices Around Fertility Awareness-Based Methods in Title X Clinics in the United States.

Objective: To understand how Title X providers currently engage with fertility awareness-based methods (FABMs) for pregnancy prevention in Title X clinics across the United States. Materials and Methods: We developed a survey to assess knowledge of fertility for purposes of pregnancy prevention, attitudes toward FABMs use for pregnancy prevention, and practices when patients request FABMs for pregnancy prevention. Results: In total, 329 participants who met all inclusion criteria completed the survey. Respondents were generally highly knowledgeable on fertility, felt neutrally toward FABMs or thought they were a nonviable option for most women, and were likely to respond to patient requests for FABMs for pregnancy prevention by providing information. Qualitative responses included several barriers to provision of FABMs for pregnancy prevention and few successes to provision. Conclusions: Fertility knowledge and discussion of specific methods increased with the number of methods included in the clinic's written materials or with the number of different FABMs someone at that clinic had been trained on. Significant clinician or administrative barriers may exist to offering FABMs to patients. Incorporating up-to-date information on a range of FABMs-rather than treating them as one method-into contraceptive counseling represents an opportunity to increase the contraceptive offering for clients who want them, leading to increased patient satisfaction and successful family planning outcomes.
