Recognizing Excellence in Maternal and Child Health (MCH) Epidemiology: The National MCH Epidemiology Awards.

Purpose: Professionals in the field of maternal and child health (MCH) epidemiology are publicly recognized by the Coalition for Excellence in MCH Epidemiology representing 16 national MCH agencies and organizations. Description: During the CityMatCH Leadership and MCH Epidemiology Conference, the national awards are presented to public health professionals for improving the health of women, children, and families. The awards have evolved over the last two decades with focus on awardees that represent more types of MCH public health professionals. Assessment: Since 2000, the Coalition has presented 111 national awards in the areas of advancing knowledge, effective practice, outstanding leadership, excellence in teaching and mentoring, early career professional achievement, and lifetime achievement. Effective practice awards were most often presented at 45 awards, followed by early career professional achievement with 20. The awardees varied by place of employment with 37 employed at academic institutions, 33 in federal government positions, 32 in state or county government, seven in non-profit and two in clinical organizations. Awards were almost equally distributed by gender with 49 presented to women and 48 to men. Assessment of career advancement among previous awardees and acknowledging workforce challenges are gaps identified within the national awards process. Conclusion: Recognition of deserving MCH professionals sets the standard for those entering the field of MCH epidemiology and offers opportunity to recognize those who have built capacity and improved the health of women, children, and families.

Geographic access to critical care obstetrics for women of reproductive age by race and ethnicity.

BACKGROUND: The goal of risk-appropriate maternal care is for high-risk pregnant women to receive specialized obstetrical services in facilities equipped with capabilities and staffing to provide care or transfer to facilities with resources available to provide care. In the United States, geographic access to critical care obstetrics varies. It is unknown whether this variation in proximity to critical care obstetrics differs by race, ethnicity, and region. OBJECTIVE: We examined the geographic access, defined as residence within 50 miles of a facility capable of providing risk-appropriate critical care obstetrics services for women of reproductive age, by distribution of race and ethnicity. STUDY DESIGN: Descriptive spatial analysis was used to assess geographic distance to critical care obstetrics for women of reproductive age by race and ethnicity. Data were analyzed geographically: nationally, by the Department of Health and Human Services regions, and by all 50 states and the District of Columbia. Dot density analysis was used to visualize geographic distributions of women by residence and critical care obstetrics facilities across the United States. Proximity analysis defined the proportion of women living within an approximate 50-mile radius of facilities. Source data included the 2015 American Community Survey from the United States Census Bureau and the 2015 American Hospital Association Annual Survey. RESULTS: Geographic access to critical care obstetrics was the greatest for Asian and Pacific Islander women of reproductive age (95.8%), followed by black (93.5%), Hispanic (91.4%), and white women of reproductive age (89.1%). American Indian and Alaska Native women had more limited geographic access (66%) in all regions. Visualization of proximity to critical care obstetrics indicated that facilities were predominantly located in urban areas, which may limit access to women in frontier or rural areas of states including nationally recognized reservations where larger proportions of white women and American Indian and Alaska Native women reside, respectively. CONCLUSION: Disparities in proximity to critical care obstetrics exist in rural and frontier areas of the United States, which affect white women and American Indian and Alaska Native women, primarily. Examining insurance coverage, interstate hospital referral networks, and transportation barriers may provide further insight into critical care obstetrics accessibility. Further exploring the role of other equity-based measures of access on disparities beyond geography is warranted.

Need for Contraceptive Services Among Women of Reproductive Age - 45 Jurisdictions, United States, 2017-2019.

Ensuring access to contraceptive services is an important strategy for preventing unintended pregnancies, which account for nearly one half of all U.S. pregnancies (1) and are associated with adverse maternal and infant health outcomes (2). Equitable, person-centered contraceptive access is also important to ensure reproductive autonomy (3). Behavioral Risk Factor Surveillance System (BRFSS) data collected during 2017-2019 were used to estimate the proportion of women aged 18-49 years who were at risk for unintended pregnancy* and had ongoing or potential need for contraceptive services.† During 2017-2019, in the 45 jurisdictions§ from which data were collected, 76.2% of women aged 18-49 years were considered to be at risk for unintended pregnancy, ranging from 67.0% (Alaska) to 84.6% (Georgia); 60.7% of women had ongoing or potential need for contraceptive services, ranging from 45.3% (Puerto Rico) to 73.7% (New York). For all jurisdictions combined, the proportion of women who were at risk for unintended pregnancy and had ongoing or potential need for contraceptive services varied significantly by age group, race/ethnicity, and urban-rural status. Among women with ongoing or potential need for contraceptive services, 15.2% used a long-acting reversible method (intrauterine device or contraceptive implant), 25.0% used a short-acting reversible method (injectable, pill, transdermal patch, or vaginal ring), and 29.5% used a barrier or other reversible method (diaphragm, condom, withdrawal, cervical cap, sponge, spermicide, fertility-awareness-based method, or emergency contraception). In addition, 30.3% of women with ongoing or potential need were not using any method of contraception. Data in this report can be used to help guide jurisdictional planning to deliver contraceptive services, reduce unintended pregnancies, ensure that the contraceptive needs of women and their partners are met, and evaluate efforts to increase access to contraception.

Standardization of State Definitions for Neonatal Abstinence Syndrome Surveillance and the Opioid Crisis.

Rates of neonatal abstinence syndrome (NAS) have increased fivefold in the past decade. To address this expanding and complex issue, state public health agencies have addressed the opioid crisis affecting newborns in diverse ways, leading to a variety of methods to quantify the burden of NAS.In an effort to understand this variability, we summarized clinical case and surveillance definitions used across jurisdictions in the United States. We confirmed that the rapid progression of the nation's opioid crisis resulted in heterogeneous processes for identifying NAS. Current clinical case definitions use different combinations of clinician-observed signs of withdrawal and evidence of perinatal substance exposure. Similarly, there is discordance in diagnosis codes used in surveillance definitions. This variability makes it difficult to produce comparable estimates across jurisdictions, which are needed to effectively guide public health strategies and interventions.Although standardization is complicated, consistent NAS definitions would increase comparability of NAS estimates across the nation and would better guide prevention and treatment efforts for women and their infants.

Policy change is not enough: engaging provider champions on immediate postpartum contraception.

Rates of short-interval pregnancies that result in unintended pregnancies remain high in the United States and contribute to adverse reproductive health outcomes. Long-acting reversible contraception methods have annual failure rates of <1%, compared with 9% for oral contraceptive pills, and are an effective strategy to reduce unintended pregnancies. To increase access to long-acting reversible contraception in the immediate postpartum period, several State Medicaid programs, which include those in Iowa and Louisiana, recently established reimbursement policies to remove the barriers to reimbursement of immediate postpartum long-acting reversible contraception insertion. We used a mixed-methods approach to analyze 2013-2015 linked Medicaid and vital records data from both Iowa and Louisiana and to describe trends in immediate postpartum long-acting reversible contraception provision 1 year before and after the Medicaid reimbursement policy change. We also used data from key informant interviews with state program staff to understand how provider champions affected policy uptake. We found that the monthly average for the number of insertions in Iowa increased from 4.6 per month before the policy to 6.6 per month after the policy; in Louisiana, the average number of insertions increased from 2.6 per month before the policy to 45.2 per month. In both states, the majority of insertions occurred at 1 academic/teaching hospital. In Louisiana, the additional increase may be due to the engagement of a provider champion who worked at both the state and facility level. Recruiting, training, engaging, and supporting provider champions, as facilitators, with influence at state and facility levels, is an important component of a multipart strategy for increasing successful implementation of state-level Medicaid payment reform policies that allow reimbursement for immediate postpartum long-acting reversible contraception insertions.

Neonatal Abstinence Syndrome: Trend and Expenditure in Louisiana Medicaid, 2003-2013.

Objectives Determine trends in incidence and expenditure for perinatal drug exposure and neonatal abstinence syndrome (NAS) among Louisiana's Medicaid population. We also describe the maternal characteristics of NAS affected infants. Methods Retrospective cohort analysis using linked Medicaid and vital records data from 2003 to 2013. Conducted incidence and cost trends for drug exposed infants with and without NAS. Also performed comparison statistics among drug exposed infants with and without NAS and those not drug exposed. Results As rate of perinatal drug exposure increased, NAS rate per 1000 live Medicaid births also increased, from 2.1 (2003) to 3.6 (2007) to 8.0 (2013) (P for trend <0.0001). Total medical cost paid by Medicaid also increased from $1.3 million to $3.6 million to $8.7 million (P for trend <0.0001). Compared with drug exposed infants without NAS and those not drug exposed, infants with NAS were more likely to be white, have feeding difficulties, respiratory distress syndrome, sepsis, and seizures, all of which had an association at P < 0.0001. Over one-third (33.2%) of the mothers of infants with NAS had an opioid dependency in combination with a mental illness; with depression being most common. Conclusions for Practice Over an 11-year period, NAS rate among Louisiana's Medicaid infants quadrupled and the cost for caring for the affected infants increased six-fold. Medicaid, as the predominant payer for pregnant women and children affected by substance use disorders, must play a more active role in expanding access to comprehensive substance abuse treatment programs.

US and territory telemedicine policies: identifying gaps in perinatal care.

BACKGROUND: Perinatal regionalization is a system of maternal and neonatal risk-appropriate health care delivery in which resources are ideally allocated for mothers and newborns during pregnancy, labor and delivery, and postpartum, in order to deliver appropriate care. Typically, perinatal risk-appropriate care is provided in-person, but with the advancement of technologies, the opportunity to provide care remotely has emerged. Telemedicine provides distance-based care to patients by consultation, diagnosis, and treatment in rural or remote US jurisdictions (states and territories). OBJECTIVE: We sought to summarize the telemedicine policies of states and territories and assess if maternal and neonatal risk-appropriate care is specified. STUDY DESIGN: We conducted a 2014 systematic World Wide Web-based review of publicly available rules, statutes, regulations, laws, planning documents, and program descriptions among US jurisdictions (N = 59) on telemedicine care. Policies including language on the topics of consultation, diagnosis, or treatment, and those specific to maternal and neonatal risk-appropriate care were categorized for analysis. RESULTS: Overall, 36 jurisdictions (32 states; 3 territories; and District of Columbia) (61%) had telemedicine policies with language referencing consultation, diagnosis, or treatment; 29 (49%) referenced consultation, 30 (51%) referenced diagnosis, and 35 (59%) referenced treatment. In all, 26 jurisdictions (22 states; 3 territories; and District of Columbia) (44%), referenced all topics. Only 3 jurisdictions (3 states; 0 territories) (5%), had policy language specifically addressing perinatal care. CONCLUSION: The majority of states have published telemedicine policies, but few specify policy language for perinatal risk-appropriate care. By ensuring that language specific to the perinatal population is included in telemedicine policies, access to maternal and neonatal care can be increased in rural, remote, and resource-challenged jurisdictions.

Sickle cell disease in pregnancy: maternal complications in a Medicaid-enrolled population.

Higher frequencies of pregnancy complications have been reported among women with sickle cell disease (SCD) compared with those without SCD; however, past studies are limited by small sample size, narrow geographic area, and use of hospital discharge data. We compared the prevalence of maternal complications among intrapartum and postpartum women with SCD to those without SCD in a large, geographically diverse sample. Data from the 2004-2010 Truven Health MarketScan(®) Multi-State Medicaid databases were used to assess the prevalence of maternal complications among intrapartum and postpartum women 15-44 years of age with and without SCD whose race was reported as black. The comparison group of women without SCD was further divided into those with chronic conditions associated with multi-organ failure and those without chronic conditions. Multivariable log-binomial regression models were used to calculate adjusted prevalence ratios for outcomes for women with SCD compared with women in the two comparison groups. Of the 335,348 black women with a delivery during 2004-2010, 1,526 had a diagnosis of SCD (0.5 %). Compared with women without SCD who had chronic conditions, women with SCD had higher prevalence of deep vein thrombosis, pulmonary embolism, obstetric shock, pneumonia, sepsis, postpartum infection, and transfusions. SCD was also positively associated with acute renal failure, cerebrovascular disorder, respiratory distress syndrome, eclampsia, postpartum hemorrhage, preterm birth, and ventilation when compared with women without SCD and chronic conditions. Overall, women with SCD have increased prevalence of pregnancy complications, even when compared with a group of women with similar risk for multi-organ failure.

Attitudes and Experiences Surrounding Female Genital Mutilation/Cutting in the United States: A Scoping Review.

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. Findings suggest that women and men from FGM/C-practicing countries living in the United States generally oppose FGM/C, and that women with FGM/C have significant physical and mental health needs and have found US healthcare providers to lack understanding of FGM/C. Future research can improve measurement of FGM/C by taking into account the sociocultural influences on FGM/C-related attitudes and experiences.

Association of Medicaid Expansion Under the Affordable Care Act With Medicaid Coverage in the Prepregnancy, Prenatal, and Postpartum Periods.

INTRODUCTION: We evaluated how the Affordable Care Act (ACA) Medicaid eligibility expansion affected perinatal insurance coverage patterns for Medicaid-enrolled beneficiaries who gave birth overall and by race/ethnicity. We also examined state-level heterogeneous impacts. METHODS: Using the 2011-2013 Medicaid Analytic eXtract and the 2016-2018 Transformed Medicaid Statistical Information System Analytic File databases, we identified 1.4 million beneficiaries giving birth in 2012 (pre-ACA expansion cohort) and 1.5 million in 2017 (post-ACA expansion cohort). We constructed monthly coverage rates for the two cohorts by state Medicaid expansion status and obtained difference-in-differences estimates of the association of Medicaid expansion with coverage overall and by race/ethnicity group (non-Hispanic White, non-Hispanic Black, and Hispanic). To explore state-level heterogeneous impacts, we divided the expansion and non-expansion states into groups based on the differences in the income eligibility limits for low-income parents in each state between 2012 and 2017. RESULTS: Medicaid expansion was associated with 13 percentage points higher coverage in the 9 to 12 months before giving birth, and 11 percentage points higher coverage at 6 to 12 months postpartum. Hispanic birthing individuals had the greatest relative increases in coverage, followed by non-Hispanic White and non-Hispanic Black individuals. In Medicaid expansion states, those who experienced the greatest increases in income eligibility limits for low-income parents generally saw the greatest increases in coverage. In non-expansion states, there was less heterogeneity between state groupings. CONCLUSIONS: Pregnancy-related Medicaid eligibility did not have major changes in the 2010s. However, states' adoption of ACA Medicaid expansion after 2012 was associated with increased Medicaid coverage before, during, and after pregnancy. The increases varied by race/ethnicity and across states.

Is polycystic ovary syndrome another risk factor for venous thromboembolism? United States, 2003-2008.

OBJECTIVE: We sought to determine prevalence and likelihood of venous thromboembolism (VTE) among women with and without polycystic ovary syndrome (PCOS). STUDY DESIGN: We performed a cross-sectional analysis using Thomson Reuters MarketScan Commercial databases for the years 2003 through 2008. The association between VTE and PCOS among women aged 18-45 years was assessed using age-stratified multivariable logistic regression models. RESULTS: Prevalence of VTE per 100,000 was 374.2 for PCOS women and 193.8 for women without PCOS. Compared with women without PCOS, those with PCOS were more likely to have VTE (adjusted odds ratio [aOR] 18-24 years, 3.26; 95% confidence interval [CI], 2.61-4.08; aOR 25-34 years, 2.39; 95% CI, 2.12-2.70; aOR 35-45 years, 2.05; 95% CI, 1.84-2.38). A protective association (odds ratio, 0.8; 95% CI, 0.73-0.98) with oral contraceptive use was noted for PCOS women. CONCLUSION: PCOS might be a predisposing condition for VTE, particularly among women aged 18-24 years. Oral contraceptive use might be protective.

Prevalence of polycystic ovary syndrome among the privately insured, United States, 2003-2008.

OBJECTIVE: The purpose of this study was to estimate the prevalence of polycystic ovary syndrome (PCOS) and its phenotypes as defined by the National Institutes of Health, Rotterdam criteria, and Androgen Society. STUDY DESIGN: Thomson Reuters MarketScan Commercial databases (Thomson Reuters Healthcare Inc, New York, NY) for 2003-2008 were used to calculate the prevalence of PCOS and to assess differences in demographic characteristics and comorbid conditions among women who were 18-45 years old with and without PCOS. RESULTS: The prevalence of PCOS was 1585.1 per 100,000; women with phenotype A or classic PCOS were most prevalent at 1031.5 per 100,000. Women with PCOS were more likely than those without PCOS to be 25-34 years old, be from the South, be infertile, have metabolic syndrome, have been seen by an endocrinologist, and have taken oral contraceptives. CONCLUSION: This is the first study to use all available criteria to estimate the prevalence of PCOS. Providers should evaluate women with menstrual dysfunction for the presence of PCOS.

Summary of neonatal and maternal transport and reimbursement policies-a 5-year update.

OBJECTIVE: To examine the number of states with neonatal and maternal transport and reimbursement policies in 2019, compared with 2014. STUDY DESIGN: We conducted a systematic review of web-based, publicly available information on neonatal and maternal transport policies for each state in 2019. Information was abstracted from rules, codes, licensure regulations, and planning and program documents, then summarized within two categories: transport and reimbursement policies. RESULT: In 2019, 42 states had a policy for neonatal transport and 37 states had a policy for maternal transport, increasing by 8 and 7 states respectively. Further, 31 states had a reimbursement policy for neonatal transport and 11 states for maternal transport, increases of 1 state per category. Overall, the number of states with policies increased from 2014 to 2019. CONCLUSION: The number of state neonatal and maternal transport policies increased; these policies may support provision of care at the most risk-appropriate facilities.

Seven years later: state neonatal risk-appropriate care policy consistency with the 2012 American Academy of Pediatrics Policy.

OBJECTIVE: To assess consistency of state neonatal risk-appropriate care policies with the 2012 AAP policy seven years post-publication. STUDY DESIGN: Systematic, web-based review of all publicly available 2019 state neonatal levels of care policies. Information on infant risk (gestational age, birth weight), technology and equipment capabilities, and availability of specialty staffing used to define neonatal levels of care was extracted for review. RESULT: Half of states (50%) had a neonatal risk-appropriate care policy. Of those states, 88% had language consistent with AAP-defined Level I criteria, 80% with Level II, 56% with Level III, and 55% with Level IV. Comparing policies (2014-2019), consistency increased in state policies among all levels of care with the greatest increase among level IV criteria. CONCLUSION: States improved consistency of policy language by each level of care, though half of states still lack policy to provide minimum standards of care to the most vulnerable infants.

Review of Publicly Available State Policies for Long-Acting Reversible Contraception Device Reimbursement.

Background: Provider challenges to accessing long-acting reversible contraception (LARC) include level of reimbursement for LARC device acquisition and cost to stock. State-level LARC device reimbursement policies that cover a greater proportion of the cost of the LARC device and enable providers to purchase LARC upfront may improve contraceptive access. Materials and Methods: To summarize state-level policies that include language on LARC device reimbursement in the outpatient setting, we conducted a systematic, web-based review among all 50 states of publicly available LARC device reimbursement policies that include coverage of LARC devices as a medical or pharmacy benefit, the use of the 340B Drug Pricing Program to purchase LARC devices, and separate payment for LARC devices outside of the Medicaid Prospective Payment System (PPS) payment rate for Federally Qualified Health Centers or Rural Health Clinics. Results: Forty-two percent (21/50) of states with publicly available state-level policies included language on LARC device reimbursement. Among the states, 24% (5/21) had coverage policies as a medical benefit, 33% (7/21) as a pharmacy benefit, and 19% (4/21) as both a medical benefit and pharmacy benefit; 38% (8/21) used the 340B Program to purchase LARC devices; and 62% (13/21) indicated separate payment for LARC devices outside of the Medicaid PPS payment rate. Conclusion: State-level policies for LARC device reimbursement vary, highlighting differences in reimbursement strategies across the U.S. Future research could explore how the implementation of these payment methods may impact LARC device reimbursement and whether increased reimbursement may improve access to the full range of contraceptive methods.

Immediate Postpartum Long-Acting Reversible Contraception: Review of Insertion and Device Reimbursement Policies.

BACKGROUND: Previous assessment of statewide policies on long-acting reversible contraception (LARC) indicate that an increasing number of states are implementing policies specifically for provision immediately postpartum, supported by current clinical guidelines. Less is known about how state policies describe payment methodologies for the insertion procedure and device costs. METHODS: We conducted a systematic, web-based review of publicly available statewide policy language on immediate postpartum LARC among all 50 states. We examined the payor/s identified in the policy and policy type, if the policy included language on the global obstetric fee, whether providers and/or facilities were authorized to bill for procedure or device costs, and if the billing mechanism was identified as inpatient and/or outpatient services. RESULTS: Three-fourths of states (76%; n = 38) had statewide policies on immediate postpartum LARC. All policies identified Medicaid as the payor, although two also included non-Medicaid plans. Language allowing for reimbursement separate from the global obstetric fee for insertion procedures was present in 76% of states; 23 states permit it and 6 do not. Device cost reimbursement separate from the fee was identified in more state policies (92%); 31 states allow it and 4 do not. More policies included inpatient or outpatient billing mechanisms for device costs (82%; n = 31) than insertion procedures (50%; n = 19). CONCLUSIONS: Medicaid reimbursement policies for immediate postpartum LARC services vary by state reimbursement process, type, and mechanism. Observed differences indicate payment methodologies more often include the cost of the device than provider reimbursement (31 states vs. 23 states). Fewer than one-half of states offer reimbursement for provider insertion fees, a significant systems barrier to contraceptive access for women who choose LARC immediately postpartum.

Designation of neonatal levels of care: a review of state regulatory and monitoring policies.

OBJECTIVE: Summarize policies on levels of neonatal care designation among 50 states and District of Columbia (DC). STUDY DESIGN: Systematic review of publicly available, web-based information on levels of neonatal care designation policies for each state/DC. Information on designating authorities, designation oversight, licensure requirement, and ongoing monitoring for designated levels of care abstracted from 2019 published rules, statutes, and regulations. RESULT: Thirty-one (61%) of 50 states/DC had designated authority policies for neonatal levels of care. Fourteen (27%) incorporated oversight of neonatal levels of care into the licensure process. Among jurisdictions with designated authority, 25 (81%) used a state agency and 15 (48%) had direct oversight. Twenty-two (71%) of 31 states with a designating authority required ongoing monitoring, 14 (64%) used both hospital reporting and site visits for monitoring with only ten requiring site visits. CONCLUSIONS: Limited direct oversight influences regulation of regionalized systems, potentially impacting facility service monitoring and consequent management of vulnerable infants.

Comparison of state risk-appropriate neonatal care policies with the 2012 AAP policy statement.

OBJECTIVE: Compare state policies with standards outlined in the 2012 AAP Policy Statement on Levels of Neonatal Care. STUDY DESIGN: Systematic, web-based review of publicly available policies on levels of care in all states in 2014. Infant risk information, equipment capabilities, and specialty staffing were abstracted from published rules, statutes, and regulations. RESULT: Twenty-two states had a policy on regionalized perinatal care. State policies vary in consistency with the AAP Policy, with 60% of states including standards consistent with Level I criteria, 48% Level II, 14% Level III, and one state with Level IV. Ventilation capability standards are highly consistent (66-100%), followed by imaging capability standards (50-90%). Policy language on specialty staffing (44-68%), and subspecialty staffing (39-50%) are moderately consistent. CONCLUSION: State policies vary in consistency, a potentially significant barrier to monitoring, regulation, uniform care provision and measurement, and reporting of national-level measures on risk-appropriate care.

Making the Case: The Importance of Using 10 Key Preconception Indicators in Understanding the Health of Women of Reproductive Age.

In 2006, the Preconception Care (PCC) Work Group and the Select Panel on PCC published 10 recommendations promoting preconception health (PCH) and healthcare for women of reproductive age. In the years following the recommendations, much research focused on specific PCH behaviors, clinical provision of care, and care financing, but no comprehensive, well-defined set of indicators was identified. In 2011, seven states developed a set of 45 PCH indicators; however, to date, no one publication has assessed the usefulness of all 45 indicators in addressing PCH. This report makes the case for reducing the original 45 indicators to a condensed set of 10 for national and state reporting by describing the use of the 45 indicators to date, describing development of evaluation criteria for narrowing the number of indicators, and identifying gaps in indicator development for provision of PCC. Using the condensed set, states can set priorities, revise and develop programs and policies, implement system changes, and better allocate resources to support interventions to improve the health of women of reproductive age during the preconception and interconception periods.
