National Trends in Health Insurance Coverage of Pregnant and Reproductive-Age Women, 2000 to 2009

Access to healthcare and depression severity in vulnerable groups the US: NHANES 2013-2018

BACKGROUND

Access to healthcare is essential for managing chronic diseases, yet it often poses a barrier, contributing to a significant burden of conditions like depression. This study aimed to investigate the association between healthcare access and depression severity in contemporary free-living adults in the US, with a focus on identifying vulnerable populations.

METHOD

Data from the National Health and Nutrition Examination Survey cycles 2013-2018 were utilized, involving 13,689 participants aged 20 years or older. Multivariable multinomial logistic regression models were conducted, adjusting for various confounding variables.

RESULTS

Approximately 17 % of US adults lacked access to healthcare, while 24 % experienced varying levels of depression severity, with 8 % having moderate-to-severe depression. More males faced challenges accessing healthcare, while more females reported diverse levels of depression. Both healthcare access and depression severity were associated with low educational attainment, low familial income, lacking spousal support, lacking health insurance coverage, and worse self-reported overall health. We found a higher vulnerability to moderate-to-severe depression among females (OR (95 % CI): 1.20 (0.91, 1.59)), individuals identifying as the Other ethnic group (1.69 (1.02, 2.79)), and those living without a spouse (1.57 (1.10, 2.26)).

LIMITATIONS

Our cross-sectional study cannot establish causality, and potential biases related to self-reported data exist.

CONCLUSIONS

Access to healthcare emerged as a crucial predictor of moderate-to-severe depression among females, individuals of the Other ethnic group, and those without a spouse. Longitudinal research is needed to confirm and enhance our understanding of factors that shape the relationship between healthcare access and depression in free-living US adults.

Associations Between Preconception Glycemia and Preterm Birth: The Potential Role of Health Care Access and Utilization

Background: Preconception diabetes is strongly associated with adverse birth outcomes. Less is known about the effects of elevated glycemia at levels below clinical cutoffs for diabetes. In this study, we estimated associations between preconception diabetes, prediabetes, and hemoglobin A1c (HbA1c) on the risk of preterm birth, and evaluated whether associations were modified by access to or utilization of health care services. Materials and Methods: We used data from Add Health, a US prospective cohort study with five study waves to date. At Wave IV (ages 24-32), glucose and HbA1c were measured. At Wave V (ages 32-42), women with a live birth reported whether the baby was born preterm. The analytic sample size was 1989. Results: The prevalence of preterm birth was 13%. Before pregnancy, 6.9% of women had diabetes, 23.7% had prediabetes, and 69.4% were normoglycemic. Compared to the normoglycemic group, women with diabetes had 2.1 (confidence interval [95% CI]: 1.5-2.9) times the risk of preterm birth, while women with prediabetes had 1.3 (95% CI: 1.0, 1.7) times the risk of preterm birth. There was a nonlinear relationship between HbA1c and preterm birth such that risk of preterm birth emerged after HbA1c = 5.7%, a standard cutoff for prediabetes. The excess risks of preterm birth associated with elevated HbA1c were four to five times larger among women who reported unstable health care coverage and among women who used the emergency room as usual source of care. Conclusion: Our findings replicate prior research showing strong associations between preconception diabetes and preterm birth, adding that prediabetes is also associated with higher risk. Policies and interventions to enhance access and utilization of health care among women before pregnancy should be examined.

Lumbopelvic Pain in Pregnancy in a Diverse Urban Patient Population: Prevalence and Risk Factors

Objective: Pregnancy lumbopelvic pain (PLPP) is a common ailment during pregnancy with physical, psychosocial, and economic consequences. Prior literature has focused on majority Caucasian patient populations; none have focused on Hispanic populations, especially in the United States. The purpose of this study was to determine the proportion of pregnant people who experience PLPP in mostly Hispanic population. Materials and Methods: Cross-sectional survey Setting: Academic medical center Patients: All pregnant people attending a prenatal visit in obstetrical offices from July 2018 through March 2020 were asked to complete a questionnaire compiling demographic, socioeconomic information as well as describe any pain symptoms. Furthermore, the Pregnancy Mobility Index (PMI), Pelvic Girdle Pain Questionnaire (PGQ), and the Questionnaire for Urinary Incontinence Diagnosis (QUID) were included. Results: In a cohort (n = 851) that was 62% Hispanic, we found a 63% point-prevalence rate for PLPP. Pregnant people who reported PLPP were further along in their pregnancy, did have significantly higher scores for the PMI and PGQ, indicating a greater level of disability, and reported issues with incontinence (QUID). Results of the logistic regression found that a higher PMI score and financial instability were factors influencing PLPP. Conclusions: In a cohort of majority Hispanic people, we found that 63% of respondents had PLPP. Our study found that a higher PMI score and financial instability were factors influencing PLPP. Clinicians should be alert to pregnant people who express their difficulties with activities of daily living as they may be at risk of PLPP, and could benefit from further evaluation and treatment.

Perioperative dexamethasone with neuraxial anesthesia for scheduled cesarean delivery and neonatal hypoglycemia

OBJECTIVE

While the use of dexamethasone for cesarean delivery to prevent post-operative nausea and vomiting has become routine, the impact on fetal glucose metabolism is unknown. We aim to examine whether perioperative dexamethasone administration prior to scheduled non-labor cesarean delivery is associated with neonatal hypoglycemia.

STUDY DESIGN

Multi-institution retrospective cohort study of singleton, full-term, non-anomalous pregnancies delivered by scheduled non-labor cesarean delivery with neuraxial anesthesia from 2013 to 2019. The exposure was intravenous dexamethasone after neuraxial anesthesia placement. Primary outcome was neonatal hypoglycemia and secondary outcomes included low Apgar, umbilical artery pH < 7.1, NICU admission, and meconium-stained amniotic fluid. A subgroup analysis was performed on pregnancies complicated by diabetes (both gestational and pre-gestational). Multivariate regression adjusting for baseline differences and potential confounders was used to the determine the strength of association between dexamethasone and adverse outcomes.

RESULTS

Of the 4991 women in the study, 2719 (54.5%) received dexamethasone. Compared to non-receipt, women receiving dexamethasone were older, more likely to be White, non-Hispanic, have private insurance, and less likely to have diabetes. Perioperative dexamethasone receipt was not associated with neonatal hypoglycemia (adjusted OR 0.90, 95% CI 0.71-1.14). In a subgroup analysis of the 466 (9.3%) pregnancies complicated by pre-gestational and gestational diabetes, 219 (47.0%) received dexamethasone and receipt was associated with a significantly increased rate of neonatal hypoglycemia (adjusted OR 1.96, 95% CI 1.28-3.00). No significant associations were found between perioperative dexamethasone and other outcomes.

CONCLUSIONS

Dexamethasone administration after neuraxial anesthesia placement for scheduled non-labor cesarean delivery is associated with altered neonatal glucose metabolism only in pregnancies complicated by diabetes.

Predictors of Community-Based Health Insurance in Ethiopia via Multilevel Mixed-Effects Modelling: Evidence from the 2019 Ethiopia Mini Demography and Health Survey

Background

The World Health Organization has endorsed a community-based health insurance scheme (CBHIS) as a shared financing plan to improve access to health services and ensure universal coverage of the healthcare delivery system. Such a contributory scheme is the most likely option to provide health insurance coverage when governments cannot offer direct health care support. Despite improvements in access to current healthcare services, Ethiopia’s healthcare delivery remained low, owing to the country’s underdeveloped healthcare finance system. As a result, the present study assessed CBHIS coverage and its predictors in Ethiopia at the individual and community level.

Methods

The availability of CBHIS was checked via a criterion: at least one of the cluster respondents had to be enrolled in CBHIS. This study was based on secondary data from the Ethiopia Mini Demography and Health Survey (EMDHS) 2019 and included 7724 respondents. The study population was described using percentage and frequency. Four multilevel mixed-effects logistic regression modelling stages were performed to control for variations due to heterogeneity across clusters, and determinant predictors of CBHIS enrollment were outplayed.

Results

The prevalence of CBHIS enrollment in Ethiopia was 33.13%. Rural residents were 3.218 times (AOR = 3.218; 95% CI: 1.521, 6.809), male household heads were 1.574 times (AOR = 1.574, 95% CI: 1.105, 2.241), getting funds from the safety net program were times 2.062 (AOR = 2.062, 95% CI: 1.297, 3.279), attending the primary educational level was 1.686 times (AOR = 1.686, 95% CI: 1.007, 2.821), bank accounts were 1.373 times (AOR = 1.373, 95% CI: 1.052, 1.792), and wealth index was 1.356 times (AOR = 1.356, 95% CI: 1.001, 1.838) more likely associated with CBHIS coverage, whereas the regions, the other religions, and women aged 20–24 had lower odds of CBHIS coverage.

Conclusion

In Ethiopia, regional healthcare expenditure per capital, religious affiliation, women age range, residents, sex of household head, funds from the safety net program, formal educational level, and having bank accounts were associated with community-based health insurance scheme coverage.

Association of Medicaid Expansion With Neuraxial Labor Analgesia Use in the United States: A Retrospective Cross-Sectional Analysis

BACKGROUND

The Affordable Care Act has been associated with increased Medicaid coverage for childbirth among low-income US women. We hypothesized that Medicaid expansion was associated with increased use of labor neuraxial analgesia.

METHODS

We performed a cross-sectional analysis of US women with singleton live births who underwent vaginal delivery or intrapartum cesarean delivery between 2009 and 2017. Data were sourced from births in 26 US states that used the 2003 Revised US Birth Certificate. Difference-in-difference linear probability models were used to compare changes in the prevalence of neuraxial labor analgesia in 15 expansion and 11 nonexpansion states before and after Medicaid expansion. Models were adjusted for potential maternal and obstetric confounders with standard errors clustered at the state level.

RESULTS

The study sample included 5,703,371 births from 15 expansion states and 5,582,689 births from 11 nonexpansion states. In the preexpansion period, the overall rate of neuraxial analgesia in expansion and nonexpansion states was 73.2% vs 76.3%. Compared with the preexpansion period, the rate of neuraxial analgesia increased in the postexpansion period by 1.7% in expansion states (95% CI, 1.6-1.8) and 0.9% (95% CI, 0.9-1.0) in nonexpansion states. The adjusted difference-in-difference estimate comparing expansion and nonexpansion states was 0.47% points (95% CI, -0.63 to 1.57; P = .39).

CONCLUSIONS

Medicaid expansion was not associated with an increase in the rate of neuraxial labor analgesia in expansion states compared to the change in nonexpansion states over the same time period. Increasing Medicaid eligibility alone may be insufficient to increase the rate of neuraxial labor analgesia.

The ACA Medicaid Expansion And Perinatal Insurance, Health Care Use, And Health Outcomes: A Systematic Review

The Affordable Care Act (ACA) Medicaid expansion increased Medicaid eligibility for low-income adults regardless of their pregnancy or parental status. Variation in states' adoption of this expansion created a natural experiment to study the effects of expanding public insurance on insurance coverage, health care use, and health outcomes during preconception, pregnancy, and postpartum. We conducted a systematic review of relevant literature on this topic, analyzing twenty-four studies published between January 2014 and April 2021. We found that the ACA Medicaid expansion increased preconception and postpartum Medicaid coverage with corresponding declines in uninsurance, private insurance coverage, and insurance churn. There was limited evidence that Medicaid expansion increased perinatal health care use or improved infant birth outcomes overall, although some studies reported reduced racial and ethnic disparities in rates of prenatal and postpartum visit attendance, maternal mortality, low birthweight, and preterm births. Stronger data collection on preconception and postpartum outcomes with sufficient sample sizes to stratify by race and ethnicity is needed to assess the full impact of the ACA and emerging Medicaid policy changes, such as the postpartum Medicaid extension.

Health Insurance Coverage and Its Associated Factors Among Reproductive-Age Women in East Africa: A Multilevel Mixed-Effects Generalized Linear Model

Background

Despite improvement in access to modern healthcare services in East African countries, health-service delivery and health status of the population remained poor mainly due to the weak health-sector financing system. Therefore, the current study aimed to assess the health insurance coverage and its associated factors among reproductive-age group (RAG) women in East Africa.

Methods

The most recent (between 2010 and 2018) Demographic and Health Surveys (DHS) data of the ten East African countries (Burundi, Comoros, Ethiopia, Kenya, Malawi, Mozambique, Tanzania, Uganda, Zambia, and Zimbabwe) were included. STATA version 16.0 statistical software was used for data processing and analysis. In the multilevel mixed-effects generalized linear model, variables with a p-value ≤0.05 were declared as significant associated factors of health insurance coverage.

Results

The overall health insurance coverage in East Africa was 7.56% (95% CI: 7.42%, 7.77%). The odds of health insurance coverage were high among educated, currently working, and rich RAG women whereas it was low among rural residents. Besides, RAG women who have media exposure, visited by field workers, and visited health facilities have a higher chance of health insurance coverage.

Conclusion

Health insurance coverage in East Africa among RAG women was below ten percent. Educational status, working status, place of residence, wealth index, media exposure, visiting health facility within 12 months and being visited by field worker were significantly associated with health insurance coverage among RAG women in East Africa. Improving women’s access to health facilities, promoting field workers’ visit, and media exposure targeting uneducated, unemployed, and rural resident women of RAG will be a gateway to promote health insurance coverage.

Preconception subsidized insurance: Prenatal care and birth outcomes by race/ethnicity

Low-income pregnant women have been Medicaid eligible since the 1980s, but the Affordable Care Act (ACA)'s expansion of Medicaid to women preconception has the potential to improve pregnancy and birth outcomes by removing delays in Medicaid enrollment. More substantially, the ACA expanded subsidized nongroup maternity coverage. Pre-ACA, nongroup health insurance had generally excluded maternity coverage and was prohibitively expensive for low-income individuals, but the ACA's creation of the Marketplace made maternity coverage mandatory and provides income-based subsidies. I use a simulated eligibility approach to measure how these two aspects of the ACA impacted pregnancy and birth outcomes for first-time mothers, paying special attention to racial-ethnic differences. I find expanding Medicaid to women prior to pregnancy significantly improves the share of women with a prenatal care visit in the first trimester for non-Hispanic Whites and Blacks. Expansions in non-Medicaid subsidized insurance, such as Marketplace insurance, significantly reduce the share of births paid by Medicaid and increased breastfeeding across all racial and ethnic groups. Neither type of subsidized insurance had significant, robust impacts on birth outcomes.

Preconception Coverage Before and After the Affordable Care Act Medicaid Expansions

OBJECTIVE

To estimate the effects of the Affordable Care Act Medicaid expansion provision that was largely implemented in 2014 on preconception insurance coverage among low-income women.

METHODS

We used a quasiexperimental, difference-in-difference design to compare changes in preconception insurance coverage among low-income women living in expansion compared with nonexpansion states before and after the Medicaid expansions. Women with family incomes 138% the federal poverty level or less who participated in the Pregnancy Risk Assessment Monitoring System from 2009 to 2015 from states that did or did not expand their Medicaid programs on January 1, 2014, were included. The exposure of interest was the state Medicaid expansion. The primary outcome was insurance status 1 month before conception. We conducted additional subgroup and sensitivity analyses to test the assumptions of the model and the robustness of the findings.

RESULTS

The study sample included 30,495 women from eight states that expanded Medicaid under the Affordable Care Act and 26,561 patients from seven states in that did not. The rate of preconception Medicaid coverage was 30.8% prepolicy and 35.6% postpolicy in nonexpansion states and 43.2% prepolicy and 56.8% postpolicy in expansion states. There was a significantly greater increase in Medicaid coverage in expansion states after the policy implementation (adjusted difference-in-difference estimate +8.6% points, 95% CI 1.1-16.0). Rates of preconception uninsurance were 44.2% prepolicy and 34.3% postpolicy in nonexpansion states and 37.4% prepolicy and 23.5% postpolicy in expansion states. There was no significant difference in the changes in uninsurance between the two groups in the postpolicy period (adjusted difference-in-difference estimate -4.1, 95% CI -11.1 to 2.9). Non-Medicaid insurance coverage was 25.3% prepolicy and 30.5% postpolicy in nonexpansion states and 19.4% prepolicy and 19.7% postpolicy in expansion states. Relative to nonexpansion states, there was a significant decrease in non-Medicaid coverage in the expansion states in the postpolicy period (adjusted difference-in-difference estimate -4.7, 95% CI -8.3 to -1.1). The results were robust to alternate model specifications and study period definitions.

CONCLUSION

Medicaid expansion was associated with increased enrollment in Medicaid before pregnancy among low-income women; however, there were no changes in the rates of uninsurance. Additional years of postpolicy data are needed to fully assess the effects of the policy change.

Trends in Tdap vaccination among privately insured pregnant women in the United States, 2009-2016

BACKGROUND

Infants younger than 6 months are at increased risk of complications and mortality from pertussis infection. In October 2012, the Advisory Committee on Immunization Practices revised its recommendation to include a Tdap dose during each pregnancy, ideally between 27 and 36 weeks gestation.

OBJECTIVE

Assess trends in Tdap vaccination coverage among privately insured pregnant women from 2009 to 2016 including timing of Tdap vaccination (before, during, or after pregnancy), trimester of vaccination for women vaccinated during pregnancy, and missed vaccination opportunities for unvaccinated women. Identify factors associated with vaccination during the optimal period of 27-36 weeks gestation.

STUDY DESIGN

Retrospective analysis of privately insured women 15-49 years who delivered live births during 2009-2016 conducted using 2009-2016 MarketScan data. Tdap vaccination coverage and the timing of Tdap vaccine administration were assessed for women continuously enrolled from 6 months before pregnancy to 1 month after delivery. Multivariable logistic regression was performed to identify factors independently associated with receipt of Tdap vaccine at 27-36 weeks gestation.

RESULTS

Tdap vaccination coverage during pregnancy increased from 0.4% in 2009 to 6.2% in 2012 and to 53.2% in 2016. The proportion of vaccinated women receiving Tdap at 27-36 weeks gestation increased from <10% in 2009 to nearly 90% in 2016, with most vaccination occurring at 27-32 weeks gestation. Women of older age, residing in a metropolitan statistical area, residing outside the South, and having a capitated health insurance plan were more likely to receive Tdap at 27-36 weeks gestation than their counterparts. Among women not vaccinated during pregnancy, 77.7% had a pregnancy-related medical claim between 27 and 36 weeks gestation.

CONCLUSION

Tdap vaccination coverage during pregnancy increased significantly from 2009 to 2016, with the greatest increase occurring after the revised Advisory Committee on Immunization Practices recommendation. Most women who did not receive Tdap vaccine had a missed vaccination opportunity during pregnancy, indicating potential for much higher vaccination coverage and consequent infant protection against pertussis.

The Affordable Care Act and Access to Care for Reproductive-Aged and Pregnant Women in the United States, 2010-2016

OBJECTIVES

To estimate the association between the Affordable Care Act (ACA), health insurance coverage, and access to care among reproductive-aged and pregnant women.

METHODS

We performed an observational study comparing current insurance type, cost-related barriers to medical care, and no usual source of care among reproductive-aged (n = 128 352) and pregnant (n = 2179) female respondents to the National Health Interview Survey in the United States, before (2010-2013) and after (2015-2016) the ACA coverage expansions.

RESULTS

Among reproductive-aged women, the ACA was associated with a 7.4 percentage-point decrease in the probability of uninsurance (95% confidence interval [CI] = -8.6, -6.2), a 3.6 percentage-point increase in Medicaid (95% CI = 2.5, 4.7), and a 3.1 percentage-point increase in nongroup private coverage (95% CI = 2.1, 4.1). The ACA was also associated with a 1.5 percentage-point decline in cost-related barriers to medical care (95% CI = -2.6, -0.5) and a 2.4 percentage-point reduction in lacking a usual source of care (95% CI = -4.5, -0.3). We did not find significant changes in insurance or cost-related barriers to care for pregnant women.

CONCLUSIONS

The ACA was associated with expanded insurance coverage and improvements in access to care for women of reproductive age, particularly for those with lower incomes.

Preconception insurance and initiation of prenatal care

OBJECTIVE

The primary objective was to determine the association between preconception insurance and initiation of prenatal care.

STUDY DESIGN

This retrospective cohort uses data from the Pregnancy Risk Assessment Monitoring System (2009-2013). Self-reported preconception insurance status was the primary exposure. The primary outcome was first trimester initiation of prenatal care. Secondary outcomes included: preterm delivery, birth weight, and the presence of birth defects. Survey-weighted generalized linear models were used to calculate risk ratios and accounted for state-level clustering.

RESULTS

Of the 181,675 included women from 32 states, 21.1% were uninsured prior to conception. 88% of insured women vs. 70% of uninsured women initiated care in the first trimester. Uninsured women were less likely to initiate care in the first trimester (adjusted relative risk (RR) 0.87 (95% confidence interval 0.85-0.89), p < 0.001) compared to women with insurance in the adjusted analysis. Among the secondary outcomes, uninsured nulliparous women had a 20% higher risk of extremely (<28 weeks) preterm delivery than those with preconception insurance (adjusted RR 1.20 (1.03-1.39), p = 0.01). Uninsured women also had a slightly increased risk of having SGA infant compared to insured women (adjusted RR 1.04 (1.01-1.09), p = 0.02). There were no differences in the other secondary outcomes.

CONCLUSIONS

Preconception insurance is associated with earlier initiation of prenatal care.

The Ethics of Perinatal Care for Black Women: Dismantling the Structural Racism in "Mother Blame" Narratives

Perinatal and neonatal nurses have a critical role to play in effectively addressing the disproportionate prevalence of adverse pregnancy outcomes experienced by black childbearing families. Upstream inequities in maternal health must be better understood and addressed to achieve this goal. The importance of maternal health before, during, and after pregnancy is illustrated with the growing and inequitable prevalence of 2 common illnesses, pregestational diabetes and chronic hypertension, and 2 common conditions during and after pregnancy, gestational diabetes and preterm birth. New care models are needed and must be structured on appropriate ethical principles for serving black families in partnership with nurses. The overarching purpose of this article is to describe the ethics of perinatal care for black women; to discuss how social determinants of health, health disparities, and health inequities affecting women contribute to poor outcomes among their children; and to provide tools to dismantle structural racism specific to "mother blame" narratives." Finally, strategies are presented to enhance the provision of ethical perinatal care for black women by nurses.

Nonmedical Use of Prescription Opioids among Pregnant U.S. Women

OBJECTIVES

Nonmedical use of opioids during pregnancy is associated with adverse outcomes for women and infants, making it a prominent target for prevention and identification. Using a nationally representative sample, we determined characteristics of U.S. pregnant women who reported prescription opioid misuse in the past year or during the past month.

METHODS

We used data from the National Survey on Drug Use and Health (2005-2014) in a retrospective analysis. The sample included 8,721 (weighted n = 23,855,041) noninstitutionalized women, ages 12 to 44, who reported being pregnant when surveyed. Outcomes were nonmedical use of prescription opioid medications during the past 12 months and during the past 30 days. Multivariable logistic regression models were created to determine correlates of nonmedical opioid use after accounting for potential confounding variables.

RESULTS

Among pregnant women in the United States, 5.1% reported nonmedical opioid use in the past year. In adjusted models, depression or anxiety in the past year was strongly associated with past year nonmedical use (adjusted odd ratio [AOR], 2.15; 95% CI, 1.52-3.04), as were past year use of alcohol (AOR, 1.56; 95% CI, 1.11-2.17), tobacco (AOR, 1.72; 95% CI, 1.17-2.53), and marijuana (AOR, 3.44; 95% CI, 2.47-4.81). Additionally, 0.9% of U.S. pregnant women reported nonmedical opioid use in the past month. Past year depression or anxiety and past month use of alcohol, tobacco, and marijuana each independently predicted past month nonmedical use.

CONCLUSIONS

Characteristics associated with nonmedical opioid use by pregnant women reveal populations with mental illness and co-occurring substance use. Policy and prevention efforts to improve screening and treatment could focus on the at-risk populations identified in this study.

Women's Health in the Age of Patient Protection and the Affordable Care Act

The Patient Protection and Affordable Care Act of 2010 is the most sweeping health care legislation in a generation. The goal of the legislation is to increase access to both public and private insurance, and to improve the affordability and quality of care. Many provisions of the bill have a direct impact on the women's health care services. This paper provides an overview of the bill's provisions that have the largest impact on women's health care and provides data on the impact of the bill to date.

Improving Medicaid: three decades of change to better serve women of childbearing age

Over the past 3 decades, major changes enhanced Medicaid's role in improving the health of women and perinatal outcomes. Reforms in the 1980s and 1990s had impact not only on coverage but also on current policy debates. Whether or not states expand eligibility under the Affordable Care Act, Medicaid is important. Increased coverage for well-woman visits, preconception care, and contraceptive methods are opportunities in gynecology. As a critical source of maternity coverage, Medicaid can improve prenatal care, reduce preterm births, limit early elective deliveries, and increase postpartum visits. Obstetrician-gynecologists play a role in translating coverage into access to quality services.

What is prenatal screening and why to do it?

Patients and providers are faced with a wide array of choices to screen for structural abnormalities, aneuploidy, and genetic diseases in the prenatal period. It is important to consider the features of the diseases being screened for, the characteristics of the screening tests used, and the population being screened when evaluating prenatal screening techniques.

Age-specific chlamydial infection among pregnant women in the United States: evidence for updated recommendations

BACKGROUND

In the United States, chlamydia screening has been recommended for all pregnant women by the Centers for Disease Control and Prevention (CDC) but only for pregnant women who are at increased risk by the US Preventive Services Task Force (USPSTF). Very limited evidence, such as age-specific chlamydia positivity in pregnant women, has been used to develop these recommendations.

METHODS

We analyzed data from a large commercial laboratory corporation in the United States in 2013. At the first prenatal visit made by women aged 15 to 44 years for whom a chlamydia test was performed between June 2008 and July 2010, we estimated positivity of chlamydia by age, insurance coverage, geographic region, and test type.

RESULTS

Of 601,001 pregnant women aged 15 to 44 years who had routine prenatal care, 62.9% had private insurance and 32.9% had Medicaid coverage, 60.3% resided in the South region, and 43.2% were aged 15 to 24 years, 26.8% were aged 25 to 29 years, and 19.1% were aged 30 to 34 years. Chlamydia positivity was 3.6% overall, and significantly decreased as age increased (15-19 years: 9.6 %; 20-24 years: 5.2%; 25-29 years: 1.8%; 30-34 years: 0.9%; and 35-44 years: 0.6%; P < 0.05).

CONCLUSIONS

Our findings of higher positivity among younger pregnant women suggest that the yield is likely to be greater from screening younger pregnant women than from screening older pregnant women to identify chlamydia infection. The benefits of harmonizing CDC and USPSTF recommendations for pregnant women could be explored by reviewing age-specific positivity data and estimating the frequency of prenatal adverse health outcomes caused by chlamydia to develop consensus regarding the age limit for pregnant women who should be screened.

Women's health

Many of the unique health issues facing women are related to reproductive health and pregnancy. However, several conditions that affect both sexes have distinct manifestations in women including cardiovascular disease, osteoporosis, and anemia. The extent of the effect that the physiological differences between men and women have on the natural course of these diseases and the validity of applying a standard treatment to both genders has not been fully explored. Historically, medical research has largely excluded women, rendering the application of evidence-based medicine to women's health issues somewhat of a misnomer. While most research in women's health originates from developed nations, consideration must be given to women in all regions of the world. Compared to women in developed nations, women in resource-poor countries are burdened with increased morbidity and mortality from gender-related health issues. In order to globally advance women's health, the physiologic and social differences between men and women must be more clearly characterized and these differences must be taken into consideration when designing research endeavors and developing health policy.

Medicaid covered births, 2008 through 2010, in the context of the implementation of health reform

BACKGROUND

Medicaid is a major source of public health care financing for pregnant women and deliveries in the United States. Starting in 2014, some states will extend Medicaid to thousands of previously uninsured, low-income women. Given this changing landscape, it is important to have a baseline of current levels of Medicaid financing for births in each state. This article aims to 1) provide up-to-date, multiyear data for all states, the District of Columbia, and Puerto Rico and 2) summarize issues of data comparability in view of increased interest in program performance and impact assessment.

METHODS

We collected 2008-2010 data on Medicaid births from individual state contacts during the winter of 2012-2013, systematically documenting sources and challenges.

FINDINGS

In 2010, Medicaid financed 45% of all births, an increase of 4% [corrected] in the proportion of all births covered by Medicaid in 2008. Percentages varied among states. Numerous data challenges were found.

CONCLUSIONS/IMPLICATIONS FOR RESEARCH AND POLICY

Consistent adoption of the 2003 birth certificate in all states would allow the National Center for Health Statistics Natality Detail dataset to serve as a nationally representative source of data for the financing of births in the United States. As states expand coverage to low-income women, women of childbearing age will be able to obtain coverage before and between pregnancies, allowing for access to services that could improve their overall and reproductive health, as well as birth outcomes. Improved birth outcomes could translate into substantial cost savings, because the costs associated with preterm births are estimated to be 10 times greater than those for full-term births.
