Maternal health: does prenatal care make a difference?

Sexual Orientation-Specific Policies Are Associated With Prenatal Care Use in the First Trimester Among Sexual Minority Women: Results From a Prospective Cohort Study

BACKGROUND

Previous research has shown sexual minority women (SMW) are more likely to report multiple maternal and infant health outcomes compared to heterosexual women and that these outcomes are moderated by the policy environment. Little is known, however, about prenatal care use disparities or the social determinants of prenatal care use for SMW.

PURPOSE

To examine the relationship between sexual orientation-specific policies that confer legal protections (e.g., hate crime protections, housing discrimination, same-sex marriage) and prenatal care use among women using a prospective, population-based data set.

METHODS

Using the National Longitudinal Study of Adolescent to Adult Health and logistic regression, we link measures of state policies to the use of prenatal care in the first trimester among women who had live births. The use of prospective data allows us to adjust for covariates associated with preconception care use prior to pregnancy (n = 586 singleton births to SMW; n = 4,539 singleton births to heterosexual women).

RESULTS

Sexual orientation-specific policies that conferred protections were associated with increased use of prenatal care among pregnancies reported by SMW (OR = 1.86, 95% CI 1.16, 2.96). In fact, in states with zero protections, we found no differences in prenatal care use by sexual minority status; however, in states with two or more protective policies, SMW were more likely to access prenatal care in the first trimester than heterosexual women. There was no relationship between sexual orientation-specific policy environments and prenatal care use among pregnancies reported by heterosexual women.

CONCLUSIONS

Recent research has documented that SMW are more likely to have adverse perinatal and obstetrical outcomes than their heterosexual peers. These findings suggest that Lesbian/Gay/Bisexual-specific policy protections may facilitate the use of prenatal care among SMW, a potentially important pathway to improve reproductive health among this population.

Severe Maternal Morbidity among Low-Income Patients with Hypertensive Disorders of Pregnancy

OBJECTIVE

 Hypertensive disorders of pregnancy (HDP) contribute significantly to the development of severe maternal morbidities (SMM), particularly among low-income women. The purpose of the study was to explore the relationship between maternal characteristics and SMM, and to investigate if differences in SMM exist among patients with HDP diagnosis.

STUDY DESIGN

 This study utilized 2017 Alabama Medicaid administrative claims. SMM diagnoses were captured using the Centers for Disease Control and Prevention's classification by International Classification of Diseases codes. Maternal characteristics and frequencies were compared using Chi-square and Cramer's V statistics. Logistic regression analyses were conducted to examine multivariable relationships between maternal characteristics and SMM among patients with HDP diagnosis. Odds ratios and 95% confidence intervals (CIs) were used to estimate risk.

RESULTS

 A higher proportion of patients experiencing SMM were >34 years old, Black, Medicaid for Low-Income Families eligible, lived in a county with greater Medicaid enrollment, and entered prenatal care (PNC) in the first trimester compared with those without SMM. Almost half of patients (46.2%) with SMM had a HDP diagnosis. After controlling for maternal characteristics, HDP, maternal age, county Medicaid enrollment, and trimester PNC entry were not associated with SMM risk. However, Black patients with HDP were at increased risk for SMM compared with White patients with HDP when other factors were taken into account (adjusted odds ratio [aOR] = 1.37, 95% CI: 1.11-1.69). Patients with HDP and SMM were more likely to have a prenatal hospitalization (aOR = 1.45, 95% CI: 1.20-1.76), emergency visit (aOR = 1.30, 95% CI: 1.07-1.57), and postpartum cardiovascular prescription (aOR = 2.43, 95% CI: 1.95-3.04).

CONCLUSION

 Rates of SMM differed by age, race, Medicaid income eligibility, and county Medicaid enrollment but were highest among patients with clinical comorbidities, especially HDP. However, among patients with HDP, Black patients had an elevated risk of severe morbidity even after controlling for other characteristics.

KEY POINTS

· Patients with SMM were more likely to have a HDP diagnosis.. · Among those with HDP, Black patients had elevated risk of SMM.. · Differences in care delivery did not explain SMM disparities..

Extending Driver's Licenses to Undocumented Immigrants: Comparing Perinatal Outcomes Following This Policy Shift

Research shows that restrictive immigration policies and practices are associated with poor health, but far less is known about the relationship between inclusive immigration policies and health. Using data from the United States natality files, we estimate associations between state laws granting undocumented immigrants access to driver's licenses and perinatal outcomes among 4,047,067 singleton births to Mexican and Central American immigrant birthing people (2008-2021). Fitting multivariable log binomial and linear models, we find that the implementation of a license law is associated with improvements in low birthweight and mean birthweight. Replicating these analyses among U.S.-born non-Hispanic White birthing people, we find no association between the implementation of a license law and birthweight. These findings support the hypothesis that states' extension of legal rights to immigrants improves the health of the next generation.

The effects of pregnancy-related Medicaid expansions on maternal, infant, and child health

Prior research has examined how late 1980s pregnancy-related Medicaid eligibility expansions influenced outcomes around the time of birth and, more recently, adult outcomes. We offer a close examination of early childhood effects to better understand the mechanism(s) underlying the improved longer-term outcomes. The restricted-access National Maternal and Infant Health Survey allows us to explore the effects of these expansions on maternal and child outcomes near the time of birth as well as three years post-birth. Our evidence suggests earlier connection with prenatal care and possible modest improvements in birthweight and gestational age. In our follow-up data, we also identify evidence of persistent effects as measured by child developmental scores. However, the most consistent finding is our strong evidence of reduced levels of maternal depression-both during the child's infancy and three years later. We conclude that the alleviation of maternal stress is one likely mechanism for the longer-term improvements in later-life outcomes identified in studies of children exposed to Medicaid in-utero and in early infancy.

The 2016 Presidential Election and Prenatal Care Utilization Among Foreign-born Hispanic Pregnant People

BACKGROUND

Few studies have evaluated the relationship between adequate and timely prenatal care among immigrant pregnant people and the recent political climate, including the 2016 election and associated campaigns.

OBJECTIVES

We examine whether the 2016 presidential election was associated with changes in prenatal care utilization among US foreign-born Hispanic pregnant people.

RESEARCH DESIGN

Interrupted time series.

SUBJECTS

All foreign-born Hispanic and US-born non-Hispanic White people delivering singleton infants from 2008 to 2017 who resided in the 23 states that fully implemented the 2003 version of the birth certificate before January 2008 (n=12,397,503).

MEASURES

We examine the relationship between the presidential election and changes in the odds of inadequate or late/no prenatal care among immigrant Hispanic pregnant people, as well as trends in prenatal care utilization before the election.

RESULTS

Our results show no unexpected changes in receipt of inadequate prenatal care, and late/no prenatal care, among the 7 monthly conception cohorts exposed to the election before the third trimester. However, we detected increases in the odds of both inadequate care and late/no prenatal care among foreign-born Hispanic pregnant people in June 2015 and January 2016, respectively. These upward level shifts persisted through the remainder of our time series ending with the cohort conceived around December 2016.

CONCLUSIONS

The worsening shifts in prenatal care utilization we observe may serve as a bellwether for worsening outcomes among immigrant women and their families. Research is therefore urgently needed to investigate the determinants and consequences of these concerning trends.

Delayed entry into prenatal care among women with pre-pregnancy health conditions, National Birth Defects Prevention Study, 1997-2011

First trimester entry into prenatal care is recommended for all women, and especially women with pre-pregnancy conditions. Our objective was to determine whether women with pre-pregnancy conditions were at lower risk of entry after the first trimester (delayed entry) into prenatal care than women without a pre-pregnancy health condition. We used data from 10,890 participants in the National Birth Defects Prevention Study who delivered liveborn infants without birth defects. Women reported pre-pregnancy conditions and timing of entry into prenatal care during a computer-assisted telephone interview. Multivariable logistic regression analyses were conducted to evaluate whether having a pre-pregnancy condition was associated with delayed entry into prenatal care compared to women without pre-pregnancy conditions. Approximately 13% of women reported delayed entry into prenatal care, and 18% of women reported a pre-pregnancy condition. Delayed entry into prenatal care was not associated with pre-pregnancy cardiometabolic or neurologic conditions. Women with thyroid conditions were less likely to report delayed entry into prenatal care (prevalence odds ratio (OR), 95% confidence interval (CI): 0.55 [0.32, 0.94]), but women with hematologic and respiratory conditions were more likely to report delayed entry into prenatal care (OR: 1.95 [1.00, 3.82] and 1.27 [0.95, 1.72], respectively), compared to those without any chronic conditions. Future research investigating the success of early prenatal care among women with thyroid conditions could identify ways to reduce delayed prenatal care among women with other pre-pregnancy conditions.

Maternal human capital and infants' health outcomes: Evidence from minimum dropout age policies in the US

The purpose of this cross-sectional study is to examine the causal relationship of maternal education and infants' health outcomes. Using birth certificate data over the years 1970–2004 and exploiting the space-time variation in Minimum Dropout Age laws to solve the endogeneity of education, we find a sizeable effect of mothers' education on their birth outcomes. An additional year of maternal education is associated with a reduction in incidences of low birth weight and preterm birth by 15.2 and 12.7 percent, respectively. The estimates are robust across various specifications and even when allowing mothers’ cohort-of-birth to vary across regions. The results suggest that the candidate mechanisms of impact include improvements in timing, quantity, and quality of prenatal care, lower negative health behavior during pregnancy such as smoking and drinking, and higher spousal education.

•

We provide causal evidence on the effect of mothers' education on birth outcomes.

•

We use Minimum Dropout Age policies as the instrument.

•

Mother education has significant impact on infants' birth outcomes.

•

Candidate mechanisms include improvements in timing, quantity, and quality of prenatal care.

The effects of incentivizing early prenatal care on infant health

We investigate the effects of incentivizing early prenatal care utilization on infant health by exploiting a reform that required expectant mothers to initiate prenatal care during the first ten weeks of gestation to obtain a one-time monetary transfer paid after childbirth. Applying a difference-in-differences design to individual-level data on the population of births and fetal deaths, we identify modest but statistically significant positive effects of the policy on neonatal health. We further provide suggestive evidence that improved maternal health-related knowledge and behaviors during pregnancy are plausible channels through which the reform might have affected fetal health.

The effect of co-payments on the take-up of prenatal tests

Noninvasive prenatal screening tests help identify genetic disorders in a fetus, but their take-up remains low in several countries. Using a regression discontinuity design, we test the causal effect of a policy that eliminated co-payments for noninvasive screening tests in Italy. We identify the treatment effects by a discontinuity in women's eligibility for a free test based on their conception date. We find that the policy increases the probability of women's undergoing noninvasive screening tests by 5.5 percentage points, and the effect varies by socioeconomic status. We do not find evidence of substitution effects with more expensive and riskier invasive diagnostic tests. In addition, the increase in take-up does not affect pregnancy termination or newborn health. We find some evidence of positive effects on mothers' health behaviors during pregnancy as measured by reductions in mothers' weight gain and hospital admissions during pregnancy, but these are statistically significant only at the 10 percent level.

Territorial differences in access to prenatal care and health at birth

We assess the impact of prenatal care on health at birth using birth certificates from the Czech Republic. We use a predictive machine learning algorithm to identify the observables affecting birth health outcomes. We control for those observables in our empirical analysis, which indicates that a more intense use of prenatal care is positively correlated with better health outcomes at birth. Exploiting the Czech adhesion to the EU in 2004, we construct an instrument to capture the geographical heterogeneous access to prenatal care across districts. Differently from the OLS results, the IV results do not capture any significant effect of prenatal care, leaving room for the hidden role of unobservable mothers' characteristics when it comes to health behaviors during pregnancy.

Optimum maternal healthcare service utilization and infant mortality in Ethiopia

Background

Ethiopia has one of the highest rates of infant mortality in the world. Utilization of maternal healthcare during pregnancy, at delivery, and after delivery is critical to reducing the risk of infant mortality. Studies in Ethiopia have shown how infant survival is affected by utilization of maternal healthcare services, however, no studies to date have investigated the relationship between optimum utilization of maternal healthcare services utilization and infant mortality. Therefore, this study examined the effect of optimum utilization of maternal healthcare service on infant mortality in Ethiopia based on the World Health Organization (WHO, 2010) guidelines.

Methods

We used nationally representative cross-sectional data from the Ethiopian Demographic and Health Survey (EDHS). Sampling weights were applied to adjust for the non-proportional allocation of the sample to the nine regions and two city administrations as well as the sample difference across urban and rural areas. A total of 7193 most recent births from mothers who had provided complete information on infant mortality, ANC visits, tetanus injections, place of delivery and skilled birth attendance during pregnancy were included. The EDHS was conducted from January to June 2016. We applied a multivariate logistic regression analysis to estimate the relationship between optimum maternal healthcare service utilization and infant mortality in Ethiopia.

Results

The findings from this study showed that optimum maternal healthcare service utilization had a significant association with infant mortality after adjusting for other socioeconomic characteristics. This implies that increased maternal healthcare service utilization decreases the rate of infant mortality in Ethiopia. The main finding from this study indicated that infant mortality was reduced by approximately 66% among mothers who had high utilization of maternal healthcare services compared to mothers who had not utilized maternal healthcare services (AOR = 0.34; 95%CI: 0.16–0.75; p-value = 0.007). Furthermore, infant mortality was reduced by approximately 46% among mothers who had low utilization of maternal healthcare services compared to mothers who had not utilized any maternal healthcare services (AOR = 0.54; 95%CI: 0.31–0.97; p-value = 0.040).

Conclusions

From this study, we concluded that optimum utilization of maternal healthcare services during pregnancy, at delivery and after delivery might reduce the rate of infant mortality in Ethiopia.

Postpartum medical utilization: The role of prenatal economic activity and living costs

This study is the first to explore the extent to which prenatal economic fluctuations affect postpartum outpatient care utilization during three-month, six-month, and one-year postpartum periods in Taiwan and to document their counter-cyclical patterns for economic activity and pro-cyclical patterns for the CPI change rate. We present evidence that medical care utilization occurring during the postpartum period is sensitive to economic activity within the first trimester of pregnancy and the CPI change rate within the second trimester. The findings herein reveal that negative prenatal economic shocks lead to a higher probability of cesarean section, more outpatient visits for depressive disorders, hypertension, gestational diabetes, and anemia in the pregnancy period, and a lower number of prenatal care visits that could deteriorate postpartum maternal health. Moreover, our results are consistent with low-salary and private-sector-employed mothers who face credit constraints and experience the risk of losing their job, respectively, during a decline in economic activity and who subsequently suffer from nutritional deficits and maternal stress that lead to postpartum health deterioration. Conversely, high-salary mothers do not face credit constraints and have greater coping ability to deal with stress and nutritional problems, while public-sector-employed mothers are affected only by nutrition.

Are Essential Women's Healthcare Services Fully Covered? A Comparative Analysis of Policy Documents in Shanghai and New York City from 1978-2017

This study aimed to analyze the changes in the 10 major categories of women's healthcare services (WHSs) in Shanghai (SH) and New York City (NYC) from 1978 to 2017, and examine the relationship between these changes and maternal mortality ratio (MMR). Content analysis of available public policy documents concerning women's health was conducted. Two indicators were designed to represent the delivery of WHSs: The essential women's healthcare service coverage rate (ESCR) and the assessable essential healthcare service coverage rate (AESCR). Spearman correlation was used to analyze the relationship between the two indicators and MMR. In SH, the ESCR increased from 10% to 90%, AESCR increased from 0% to 90%, and MMR decreased from 24.0/100,000 to 1.01/100,000. In NYC, the ESCR increased from 0% to 80%, the AESCR increased from 0% to 60%, and the MMR decreased from 24.7/100,000 to 21.4/100,000. The MMR significantly decreased as both indicators increased (p < 0.01). Major advances have been made in women's healthcare in both cities, with SH having a better improvement effect. A common shortcoming for both was the lack of menopausal health service provision. The promotion of women's health still needs to receive continuous attention from governments of SH and NYC. The experiences of the two cities showed that placing WHSs among policy priorities is effective in improving service status.

Barriers to Prenatal Care Among Food-Insufficient Women: Findings from the Pregnancy Risk Assessment Monitoring System

Background: This study examines the relationship among food insufficiency, adequacy of prenatal care, and barriers to prenatal care. Materials and Methods: Using data from the Pregnancy Risk Assessment Monitoring System (PRAMS), 2009-2016, negative binomial and logistic regression models were used to assess the association among food insufficiency during pregnancy, late onset of prenatal care, the number of prental care visits, as well as barriers to prenatal care. Results: Findings indicate that food insufficiency is associated with not initiating prenatal care during the first trimester and having fewer overall visits. In addition, food insufficiency is associated with more overall barriers to prenatal care, and this association operates through several specific barriers, including not having enough money, lacking transportation to get to the clinic or doctor's office, not being able to get time off work, not having a Medicaid card, having too many other things going on, and having no one to take care of children. Conclusion: Considering the adverse consequences of both food insufficiency and a lack of sufficient prenatal care for maternal and child health, study findings suggest a need to develop targeted interventions that expand access and remove barriers to prenatal care among food-insufficient women.

Integrated substance use and prenatal care delivery in the era of COVID-19

The COVID-19 pandemic has directly impacted integrated substance use and prenatal care delivery in the United States and has driven a rapid transformation from in-person prenatal care to a hybrid telemedicine care model. Additionally, changes in regulations for take home dosing for methadone treatment for opioid use disorder due to COVID-19 have impacted pregnant and postpartum women. We review the literature on prenatal care models and discuss our experience with integrated substance use and prenatal care delivery during COVID-19 at New England's largest safety net hospital and national leader in substance use care. In our patient-centered medical home for pregnant and postpartum patients with substance use disorder, patients' early responses to these changes have been overwhelmingly positive. Should clinicians continue to use these models, thoughtful planning and further research will be necessary to ensure equitable access to the benefits of telemedicine and take home dosing for all pregnant and postpartum patients with substance use disorder.

Factors Associated With a Trusting Relationship Between Pregnant and Postpartum Women With Substance Use Disorders and Maternity Nurses

Trusting relationships between pregnant and postpartum women with substance use disorders (SUDs) and maternity nurses can improve health outcomes for women and their infants. This study was conducted to identify factors associated with the formation of trust in these nurse–patient relationships. Using a qualitative description approach, semi-structured interviews were conducted with 10 women who used substances during pregnancy and 15 maternity nurses. The narratives were analyzed with standard content analytic techniques. Findings revealed that six characteristics of nurses and five characteristics of women fostered or hindered the formation of trusting relationships. The characteristics of the maternity nurses were (a) interpersonal connections, (b) demeanor toward women, (c) ways of providing care, (d) approaches to providing information, (e) attitudes toward substance use, and (f) addiction expertise. The characteristics of the women were (a) engagement with nurses, (b) demeanor toward nurses, (c) attitudes toward care, (d) investment in recovery, and (e) ways of interacting with infant. The characteristics provide a framework by which maternity nurses can examine their attitudes and behaviors toward women with SUDs and inform the development of strategies to enhance their practice with this population.

Randomized controlled trial of the COPE-P intervention to improve mental health, healthy lifestyle behaviors, birth and post-natal outcomes of minority pregnant women: Study protocol with implications

BACKGROUND

Emotionally distressed pregnant minority women experience multiple adverse outcomes, including pre-eclampsia, preterm birth, operative deliveries and low birth weight. Although the United States Preventive Services Task Force recommends screening in pregnant women, many practices do not screen because efficacious interventions and systems are not in place to treat them.

AIM

Purpose of this randomized controlled trial (RCT) is to test a group delivered manualized cognitive-behavioral skills building intervention entitled COPE-P versus an attention control program on the mental health, birth and postpartum outcomes of minority pregnant women experiencing depressive, anxiety and stress symptoms.

METHODS

Design is a longitudinal randomized block RCT with repeated measures (beginning with screening prior to 18 weeks, group prenatal care in both groups from 16 + 1 to 31 + 1 weeks and ending at 6 months postpartum) at two study sites (New York city and Columbus, Ohio). Race/ethnicity is being blocked to ensure equal numbers of Hispanic and Black women. 384 women are being recruited from antenatal clinics if they are: between 18 and 40 years; in an uncomplicated singleton pregnancy <18 weeks; and self-identify as Black or Hispanic. Valid and reliable measures are being used to assess healthy lifestyle behaviors and mental health outcomes immediately following the interventions, six - eight weeks postpartum and at the children's six-month well baby visit. Birth and delivery outcomes also are being assessed.

CONCLUSION

If found to be efficacious, the COPE-P intervention could be a key solution to managing those with emotional distress and improving their outcomes.

New evidence on the impact of the quality of prenatal care on neonatal and infant mortality in India

Evidence on the impact of the quality of prenatal care on childhood mortality is limited in developing countries, including India. Therefore, using nationally representative data from the latest round of the National Family Health Survey (2015–16), this study examined the impact of the quality of prenatal care on neonatal and infant mortality in India using a multivariable binary logistic regression model. The effect of the essential components of prenatal care services on neonatal and infant mortality were also investigated. The results indicate that improvement in the quality of prenatal care is associated with a decrease in neonatal (OR: 0.93, 95% CI: 0.91–0.97) and infant (OR: 0.94, 95% CI: 0.92–0.96) mortality in India. Tetanus toxoid vaccination, consumption of iron–folic acid tablets during pregnancy and having been weighed during pregnancy were statistically associated with a lower risk of neonatal and infant mortality. Educating women on pregnancy complications was also associated with a lower risk of neonatal mortality. No effect of blood pressure examination, blood test and examination of the abdomen during pregnancy were found on either of the two indicators of childhood mortality. Although the coverage of prenatal care has increased dramatically in India, the quality of prenatal care is still an area of concern. There is therefore a need to ensure high-quality prenatal care in India.

Measuring perinatal and postpartum quality of life of women and associated factors in semi-urban Bangladesh

PURPOSE

The objective of this study was to measure the health-related quality of life (HRQoL) among pregnant women in the perinatal and postpartum periods and determine influencing factors that predict their HRQoL.

METHODS

The study was conducted among pregnant women who live in a semi-urban area of Chandpur, Bangladesh. A total of 465 women were recruited. The EuroQoL 5-Dimension 3-Level (EQ-5D-3L) and EuroQoL visual analog scale (EQ-VAS) instruments were used to measure the HRQoL of participants. Two-sample mean test (t test) was performed to examine the changes in HRQoL between the perinatal and postnatal periods of the same individuals. Multivariate linear regression was employed to identify the factors influencing HRQoL during the two periods.

RESULTS

Overall, the HRQoL scores improved significantly from the perinatal (0.49) to postpartum (0.86) period. Approximately 58% of women experienced moderate or extreme levels of health problems during the perinatal period regardless of their health status. However, most women had significantly improved health status in the postpartum period. Gestational weight gain and recommended postnatal care were significantly associated with improved HRQoL. Factors that negatively influenced changes in HRQoL included adolescent motherhood, caesarean delivery, inadequate antenatal care consultations and living in a poor household, during both the perinatal and postpartum periods.

CONCLUSIONS

Overall health status is found to be poor among women during the perinatal period compared with the postpartum period. The study indicates that interventions to address the influencing factors are needed to ensure better quality of life for women both pre- and post-birth. Community-based initiatives, such as awareness building, might address negative factors and subsequently improve health status and reduce adverse health outcomes related to pregnancy and postnatal care.

Demand-Side Causes and Covariates of Late Antenatal Care Access in Cape Town, South Africa

Objectives The objective of this study was to investigate the causes and covariates of late antenatal care access in South Africa. Methods A cross-sectional study was conducted, interviewing 221 women at four public-sector labour wards in Cape Town, South Africa in 2014. A definition of late attendance as attending ≥ 5 months was used. Data were analysed using univariate, bivariate and multivariate methods. Results Of the women who attended antenatal care at a public-sector clinic (n = 213, 96.4%), more than half (51.2%) attended ≥ 3 months and < 5 months, and a quarter (26.3%) attended ≥ 5 months. For those attending ≥ 5 months, 51.8% cited late recognition of pregnancy as the major reason for delayed attendance. Supply-side barriers were not identified as large contributing factors to delayed attendance. Late antenatal care access was predominantly associated with demand-side factors. Women who accessed antenatal care ≥ 5 months were more likely to be in the poorest 40% of the wealth-index distribution (p = 0.034) and to not have completed high school (p = 0.006). They were also more likely to report alcohol consumption during pregnancy (p = 0.020) and be multiparous (p = 0.035). Having completed high school was protective of late antenatal care access in stepwise logistic regression analysis (OR 0.403, CI 0.210-0.773, p < 0.01). For women who attended ≥ 3 months, late access was associated with unwanted pregnancy (p = 0.030). Conclusions for Practice Improved access to pregnancy tests could assist in earlier pregnancy identification. Interventions to increase awareness of the importance of early antenatal care attendance among vulnerable women may help.

Understanding the determinants of maternal mortality: An observational study using the Indonesian Population Census

BACKGROUND

For countries to contribute to Sustainable Development Goal 3.1 of reducing the global maternal mortality ratio (MMR) to less than 70 per 100,000 live births by 2030, identifying the drivers of maternal mortality is critically important. The ability of countries to identify the key drivers is however hampered by the lack of data sources with sufficient observations of maternal death to allow a rigorous analysis of its determinants. This paper overcomes this problem by utilising census data. In the context of Indonesia, we merge individual-level data on pregnancy-related deaths and households' socio-economic status from the 2010 Indonesian population census with detailed data on the availability and quality of local health services from the Village Census. We use these data to test the hypothesis that health service access and quality are important determinants of maternal death and explain the differences between high maternal mortality and low maternal mortality provinces.

METHODS

The 2010 Indonesian Population Census identifies 8075 pregnancy-related deaths and 5,866,791 live births. Multilevel logistic regression is used to analyse the impacts of demographic characteristics and the existence of, distance to and quality of health services on the likelihood of maternal death. Decomposition analysis quantifies the extent to which the difference in maternal mortality ratios between high and low performing provinces can be explained by demographic and health service characteristics.

FINDINGS

Health service access and characteristics account for 23% (CI: 17.2% to 28.5%) of the difference in maternal mortality ratios between high and low-performing provinces. The most important contributors are the number of doctors working at the community health centre (8.6%), the number of doctors in the village (6.9%) and distance to the nearest hospital (5.9%). Distance to health clinics and the number of midwives at community health centres and village health posts are not significant contributors, nor is socio-economic status. If the same level of access to doctors and hospitals in lower maternal mortality Java-Bali was provided to the higher maternal mortality Outer Islands of Indonesia, our model predicts 44 deaths would be averted per 100,000 pregnancies.

CONCLUSION

Indonesia has employed a strategy over the past several decades of increasing the supply of midwives as a way of decreasing maternal mortality. While there is evidence of reductions in maternal mortality continuing to accrue from the provision of midwife services at village health posts, our findings suggest that further reductions in maternal mortality in Indonesia may require a change of focus to increasing the supply of doctors and access to hospitals. If data on maternal death is collected in a subsequent census, future research using two waves of census data would prove a useful validation of the results found here. Similar research using census data from other countries is also likely to be fruitful.

The impact of expanded health insurance coverage for unauthorized pregnant women on prenatal care utilization

OBJECTIVE

The objective of this study was to investigate the effect of expanding Medicaid health insurance coverage for unauthorized women on prenatal care utilization.

DESIGN AND SAMPLE

A natural experiment design was used. We examined the prenatal care utilization of 20,876 unauthorized women from Nebraska, which expanded Medicaid coverage for unauthorized women, and South Carolina, which has never expanded coverage.

MEASURES

Measurements of prenatal care utilization included adequate prenatal care using the Kotelchuck Index and the number of prenatal care visits. The policy independent variable of interest was an interaction between the policy years (2007-2009) and Nebraska residence. Demographic characteristics were included as covariates. Analysis entailed a difference-in-difference approach to compare prenatal care utilization by state, both before and after legislation was passed to fund care among unauthorized women in Nebraska.

RESULTS

Women with insurance coverage were more likely to utilize prenatal services. Unauthorized women living in Nebraska during Medicaid expansion were 28% more likely to receive adequate prenatal care (OR = 1.28, p < 0.01) and had about one more prenatal care visit (IRR = 1.05, p < 0.01) than women who did not have expanded Medicaid coverage.

CONCLUSIONS

Findings have important public health policy implications to support improved birth outcomes among native-born infants of unauthorized women.

Health-related quality of life determinants among Rwandan women after delivery: does antenatal care utilization matter? A cross-sectional study

BACKGROUND

Despite the widespread use of antenatal care (ANC), its effectiveness in low-resource settings remains unclear. In this study, self-reported health-related quality of life (HRQoL) was used as an alternative to other maternal health measures previously used to measure the effectiveness of antenatal care. The main objective of this study was to determine whether adequate antenatal care utilization is positively associated with women's HRQoL. Furthermore, the associations between the HRQoL during the first year (1-13 months) after delivery and socio-economic and demographic factors were explored in Rwanda.

METHODS

In 2014, we performed a cross-sectional population-based survey involving 922 women who gave birth 1-13 months prior to the data collection. The study population was randomly selected from two provinces in Rwanda, and a structured questionnaire was used. HRQoL was measured using the EQ-5D-3L and a visual analogue scale (VAS). The average HRQoL scores were computed by demographic and socio-economic characteristics. The effect of adequate antenatal care utilization on HRQoL was tested by performing two multivariable linear regression models with the EQ-5D and EQ-VAS scores as the outcomes and ANC utilization and socio-economic and demographic variables as the predictors.

RESULTS

Adequate ANC utilization affected women's HRQoL when the outcome was measured using the EQ-VAS. Social support and living in a wealthy household were associated with a better HRQoL using both the EQ-VAS and EQ-5D. Cohabitating, and single/unmarried women exhibited significantly lower HRQoL scores than did married women in the EQ-VAS model, and women living in urban areas exhibited lower HRQoL scores than women living in rural areas in the ED-5D model. The effect of education on HRQoL was statistically significant using the EQ-VAS but was inconsistent across the educational categories. The women's age and the age of their last child were not associated with their HRQoL.

CONCLUSIONS

ANC attendance of at least four visits should be further promoted and used in low-income settings. Strategies to improve families' socio-economic conditions and promote social networks among women, particularly women at the reproductive age, are needed.

Disparities in Self-Reported Prenatal Counseling: Does Immigrant Status Matter?

Immigrant women face unique barriers to prenatal care access and patient-provider communication. Yet, few prior studies have examined U.S.-born/immigrant differences in the content of care. The purpose of this study was to investigate the roles of immigrant status, English proficiency and race/ethnicity on the receipt of self-reported prenatal counseling using nationally representative data. We used data from the Early Childhood Longitudinal Study-Birth Cohort (N ≈ 8100). We investigated differences in self-reported prenatal counseling by immigrant status, English proficiency, and race/ethnicity using logistic regression. Counseling topics included diet, smoking, drinking, medication use, breastfeeding, baby development and early labor. In additional analyses, we separately examined these relationships among Hispanic, Mexican and Non-Hispanic (NH) Asian women. Neither immigrant status nor self-reported English proficiency was associated with prenatal counseling. However, we found that being interviewed in a language other than English language by ECLS-B surveyors was positively associated with counseling on smoking (OR, 2.599; 95% CI, 1.229-5.495) and fetal development (OR, 2.408; 95% CI, 1.052-5.507) among Asian women. Race/ethnicity was positively associated with counseling, particularly among NH black and Hispanic women. There is little evidence of systematic overall differences in self-reported prenatal counseling between U.S.-born and immigrant mothers. Future research should investigate disparities in pregnancy-related knowledge among racial/ethnic subgroups.

The impact of prenatal care quality on neonatal, infant and child mortality in Zimbabwe: evidence from the demographic and health surveys

The impact of the quality of prenatal care on child mortality outcomes has received less attention in sub-Saharan Africa. This study endeavoured to explore the effect of the quality of prenatal care and its individual components on neonatal, infant and under-five mortality. The empirical analysis uses data from the three most recent waves of the nationally representative Demographic and Health Survey for Zimbabwe conducted in 1999, 2005/06 and 2010/11. The results indicate that a one-unit increase in the quality of prenatal care lowers the prospect of neonatal, infant and under-five mortality by approximately 42.33, 30.86 and 28.65%, respectively. These findings remained roughly the same even after adjusting for potential mediating factors. Examining the effect of individual prenatal care components on child mortality revealed that women who receive information on possible complications arising during pregnancy are less liable to experience a neonatal death. Similarly, women who had blood pressure checks and tetanus immunizations were less likely to experience an infant or under-five death. We did not find any statistically meaningful impact on child mortality outcomes of blood and urine sample checks, iron tablet consumption, and the receipt of malarial tablets. Overall, our results suggest the need for public health policymakers to focus on ensuring high-quality prenatal care to enhance the survival prospects of Zimbabwe's infants.

The Effects of Prenatal Care Utilization on Maternal Health and Health Behaviors

While many economic studies have explored the role of prenatal care in infant health production, the literature is sporadic on the effects of prenatal care on the mother. This research contributes to this understudied but important area using a unique large dataset of sibling newborns delivered by 0.17 million mothers. We apply within-mother estimators to find robust evidence that poor prenatal care utilization due to late onset of care, low frequency of care visits, or combinations of the two significantly increases the risks of maternal insufficient gestational weight gain, prenatal smoking, premature rupture of membranes, precipitous labor, no breastfeeding, postnatal underweight, and postpartum smoking. The magnitude of the estimates relative to the respective sample means of the outcome variables ranges from 3% to 33%. The results highlight the importance of receiving timely and sufficient prenatal care in improving maternal health and health behaviors during pregnancy as well as after childbirth.

Maternal Health Care Services Access Index and Infant Survival in Nigeria

Background

Infant mortality rate in Nigeria is among the highest world-wide. Utilization of modern health care facilities during pregnancy and at delivery reduces infant mortality rate. We examined the relationship between Infant Mortality (IM) and Maternal Health Care Services Access Index (MHCI) in Nigeria.

Methods

This cross-sectional study utilized 2013 NDHS data and included women aged 15–49 years (n=12511). MHCI was obtained from information on antenatal visit, antenatal attendance, tetanus toxoid injection during pregnancy, place of delivery and birth attendance. Cox-proportional hazard and Brass models were used for the analysis (α=0.05).

Results

Mean MHCI was higher among women with lower prevalence of IM. About 5.1% and 3.4% of the women with none and complete MHCI had experienced infant deaths respectively. The hazard of experienced infant deaths was 1.497(1.068–2.098) and 1.466(1.170–1.836) significantly higher among women with no and low MHCI respectively than those with complete MHCI. This pattern was observed when other factors were used as control. The refined IM probability (range=0.0482–0.1102) and IM rates (range=50–119) increased with reduction in the level of MHCI. The IM rate reduces from 119 per 1,000 live births among women whose MHCI score was zero to 50 per 1,000 live births among those with complete MHCI score.

Conclusion

Infant death was least experienced among women who had complete MHCI. If women optimize utilization of health facility during pregnancy and delivery, infant deaths will reduce in Nigeria.

A Longitudinal Study of Changes in Prenatal Care Utilization Between First and Second Births and Low Birth Weight

OBJECTIVES

Because previous analyses of prenatal care (PNC) utilization and risk of low birth weight (LBW) may have been influenced by selection bias, we conducted a study using longitudinal data of women with repeat pregnancies.

METHODS

We analyzed Washington State birth certificates of first and second live births (2003-2012). We estimated relative risk (RR) of LBW at second birth associated with Kotelchuck Index PNC level among women stratified by level of PNC in their first birth (n = 67,571).

RESULTS

Among women with inadequate PNC prior to their first birth (n = 10,355), women with intermediate or adequate PNC before their second birth (n = 7464) had a reduced risk of LBW (adjusted RR 0.61, 95% CI: 0.48, 0.78) compared to those whose PNC level remained inadequate. Likewise, among women with intermediate or adequate PNC prior to their first birth (n = 57,216), those with inadequate PNC before the second birth (n = 7095) had higher risk of LBW (adjusted RR 1.59, 95% CI: 1.36, 1.85) compared to those who remained at intermediate or adequate PNC.

CONCLUSIONS

Our findings support the hypothesis that PNC decreases LBW risk at second birth, independent of factors related to the utilization of PNC at first birth.

Anatomy of Good Prenatal Care: Perspectives of Low Income African-American Women on Barriers and Facilitators to Prenatal Care

BACKGROUND

Although early, consistent prenatal care (PNC) can be helpful in improving poor birth outcomes, rates of PNC use tend to be lower among African-American women compared to Whites. This study examines low-income African-American women's perspectives on barriers and facilitators to receiving PNC in an urban setting.

METHODS

We conducted six focus groups with 29 women and individual structured interviews with two women. Transcripts were coded to identify barriers and facilitators to obtaining PNC; codes were reviewed to identify emergent themes.

RESULTS

Barriers to obtaining PNC included structural barriers such as transportation and insurance, negative attitudes towards PNC, perceived poor quality of care, unintended pregnancy, and psychosocial stressors such as overall life stress and chaos. Facilitators of PNC included positive experiences such as trusting relationships with providers, respectful staff and providers, and social support.

CONCLUSIONS

Findings suggest important components in an ideal PNC model to engage low-income African-American women.

Effect of TV and radio family planning messages on the probability of modern contraception utilization in post-Soviet Central Asia

This study evaluates the effects of family planning message broadcast on radio and TV on the probability of modern contraception utilization in post-Soviet Central Asia. Viewing family planning messages on TV improves the chances of using modern contraception for a woman who actually saw the messages by about 11 and 8 per cent in Kyrgyzstan and Tajikistan, respectively. If every woman in Kyrgyzstan and Tajikistan had an opportunity to watch a family planning message on TV, then the likelihood of using modern contraception would have improved by 10 and 7 per cent in Kyrgyzstan and Tajikistan, respectively. By contrast, the effect of hearing family planning messages on radio is not significant in both countries. © 2015 The Authors.

KEY MESSAGES

Viewing family planning messages on TV improves the chances of using modern contraception for a woman who actually saw the messages by about 11 and 8 per cent in Kyrgyzstan and Tajikistan, respectively. If every woman in Kyrgyzstan and Tajikistan had an opportunity to watch a family planning message on TV, then the probability of using modern contraception would have improved by 10 and 7 per cent in Kyrgyzstan and Tajikistan, respectively. Consequently, using TV family planning messages in both countries should be encouraged. In comparison, the effect of hearing family planning messages on radio is not significant in both countries.

A multilevel analysis of prenatal care and birth weight in Kenya

The paper investigates the effect of adequate use of prenatal care on birth weight in Kenya using data from the Kenya Demographic and Health Survey of 2008-2009 together with additional administrative data. Both a single-level model and a multi-level model are estimated. The estimation strategy controls for potential sample selection bias, potential endogeneity of prenatal care, and potential unobserved heterogeneity. The results indicate that adequate use of prenatal care increases birth weight, holding other factors constant. We further observe that the single-level model overstates the effect of prenatal care on birth weight. The results imply that infant health can be improved by using prenatal care adequately. The study calls for the pursuit of policies that encourage adequate use of prenatal care by expectant mothers such as ensuring availability of skilled health care providers such as doctors and nurses at prenatal care clinics, reducing the average distances mothers have to cover when seeking prenatal care services, intensifying education of females as a way of empowering them to be able to make the right choices regarding when to seek prenatal care and from whom, and increasing income opportunities for households.

The effect of maternal healthcare on the probability of child survival in Azerbaijan

This study assesses the effects of maternal healthcare on child survival by using nonrandomized data from a cross-sectional survey in Azerbaijan. Using 2SLS and simultaneous equation bivariate probit models, we estimate the effects of delivering in healthcare facility on probability of child survival taking into account self-selection into the treatment. For women who delivered at healthcare facilities, the probability of child survival increases by approximately 18%. Furthermore, if every woman had the opportunity to deliver in healthcare facility, then the probability of child survival in Azerbaijan as a whole would have increased by approximately 16%.

Prevalence and correlates of food insecurity among students attending a midsize rural university in Oregon

OBJECTIVE

To examine the prevalence and identify correlates of food insecurity among students attending a rural university in Oregon.

METHODS

Cross-sectional nonprobability survey of 354 students attending a midsize rural university in Oregon during May, 2011. The main outcome was food insecurity measured using the US Department of Agriculture Household Food Security Survey Module: 6-Item Short Form. Socioeconomic and demographic variables were included in multivariate logistic regression models.

RESULTS

Over half of students (59%) were food insecure at some point during the previous year. Having fair/poor health (odds ratio [OR], 2.08; 95% confidence interval [CI], 1.07-4.63), being employed (OR, 1.73; 95% CI, 1.04-2.88), and having an income < $15,000/y (OR, 2.23; 95% CI, 1.07-4.63) were associated with food insecurity. In turn, good academic performance (grade point average of ≥ 3.1) was inversely associated with food insecurity.

CONCLUSIONS

Food insecurity seems to be a significant issue for college students. It is necessary to expand research on different campus settings and further strengthen support systems to increase access to nutritious foods for this population.

Effects of a Brief, Prevention-Focused Parenting Education Program for New Mothers

We evaluated the effects of a parenting program, Baby and You, on parenting knowledge, parenting morale, and social support using a single-group, pre-test, and post-test design with 159 Canadian mothers of infants aged 2 to 9 months old. Baby and You is a prevention-focused parenting program (PFPP) to improve maternal and infant health through education and social support. The 4-week curriculum focuses on infant development and safety, parent–child relationships, maternal self-care, and community resources. We computed repeated-measures ANOVAs separately for scores on Parenting Knowledge Scale, Parenting Moral Index, and Family Support Scale. We found a significant increase between pre-test and post-test on parenting knowledge, but not parenting morale or social support. Parenting morale may be a stable construct that shows little change over time. It may take more than 4 weeks of programming for mothers to identify and integrate new sources of social support.

The influence of personal and group racism on entry into prenatal care among African American women

BACKGROUND

Racism has been hypothesized as a barrier to accessing health care. No quantitative study has directly assessed its influence on women's initiation of prenatal care (PNC). We examined the relationship between PNC entry and experiences of personal and group racism among low-income, African-American (AA) women. We also examined whether the use of denial of racism as a coping mechanism was associated with a delay in accessing PNC.

METHODS

Using a prospective/retrospective cohort design we collected data from 872 AA women (prenatally, n = 484; postpartum, n = 388). Multinomial logistic regression was used to assess the relationship between the overall denial of racism index and PNC initiation.

FINDINGS

PNC entry was not associated with personal experiences of racism (p = .33); it was significantly associated with group experiences (p < .01).

CONCLUSION

Denial of racism experienced by other AAs was a barrier to early PNC among low-income, AA women. Delayed access to PNC may be rooted in the avoidance of racialized experiences among less empowered women when faced with discrimination. Our findings have important implication for the engagement of AA women into the PNC delivery system and the health care system postpartum.

Effects of prenatal care on child health at age 5

The broad goal of contemporary prenatal care is to promote the health of the mother, child, and family through the pregnancy, delivery, and the child's development. Although the vast majority of mothers giving birth in developed countries receive prenatal care, past research has not found compelling evidence that early or adequate prenatal care has favorable effects on birth outcomes. It is possible that prenatal care confers health benefits to the child that do not become apparent until after the perinatal period. Using data from a national urban birth cohort study in the US, we estimate the effects of prenatal care on four markers of child health at age 5-maternal-reported health status, asthma diagnosis, overweight, and height. Prenatal care, defined a number of different ways, does not appear to have any effect on the outcomes examined. The findings are robust and suggest that routine health care encounters during the prenatal period could potentially be used more effectively to enhance children's health trajectories. However, future research is needed to explore the effects of prenatal care on additional child health and developmental outcomes as well as the effects of preconceptional and maternal lifetime healthcare on child health.

Copula bivariate probit models: with an application to medical expenditures

The bivariate probit model is frequently used for estimating the effect of an endogenous binary regressor (the 'treatment') on a binary health outcome variable. This paper discusses simple modifications that maintain the probit assumption for the marginal distributions while introducing non-normal dependence using copulas. In an application of the copula bivariate probit model to the effect of insurance status on the absence of ambulatory health care expenditure, a model based on the Frank copula outperforms the standard bivariate probit model.

Life stressors and barriers to timely prenatal care for women with high-risk pregnancies residing in rural and nonrural areas

PURPOSE

To identify the contribution of life stressors and barriers to the untimely initiation of prenatal care for women with high-risk pregnancies living in rural and nonrural areas.

METHODS

Data collected in 10 U.S. states by the 2006-2008 Pregnancy Risk Assessment Monitoring System (PRAMS) were used (n = 34,161). Data were weighted to reflect the PRAMS complex survey design. Separate logistic regression models derived adjusted odds ratios for untimely prenatal care initiation based on several life stressors and barriers.

RESULTS

Women with high-risk pregnancies living in rural areas were more likely to report late initiation of prenatal care (17.5% vs. 14.6%). The most frequently reported life stressors were the same for both cohorts: Moving, having a very sick family member, arguing more than usual with their partners, and having bills they could not pay. The most frequently cited barriers were also the same for both groups: Not having enough money or insurance for health care visits and not being able to get an appointment when they wanted one. Having two or more barriers increased the risk of late prenatal care initiation by 2.85-fold for rural women and 2.01-fold for nonrural women.

CONCLUSION

To increase timely prenatal care initiation, preconception interventions are needed that address common life stressors and barriers shared by women living in rural and nonrural areas.

Descriptive analysis of childbirth healthcare costs in an area with high levels of immigration in Spain

Background

The aim of this study was to estimate the cost of childbirth in a teaching hospital in Barcelona, Spain, including the costs of prenatal care, delivery and postnatal care (3 months). Costs were assessed by taking into account maternal origin and delivery type.

Methods

We performed a cross-sectional study of all deliveries in a teaching hospital to mothers living in its catchment area between October 2006 and September 2007. A process cost analysis based on a full cost accounting system was performed. The main information sources were the primary care program for sexual and reproductive health, and hospital care and costs records. Partial and total costs were compared according to maternal origin and delivery type. A regression model was fit to explain the total cost of the childbirth process as a function of maternal age and origin, prenatal care, delivery type, maternal and neonatal severity, and multiple delivery.

Results

The average cost of childbirth was 4,328€, with an average of 18.28 contacts between the mother or the newborn and the healthcare facilities. The delivery itself accounted for more than 75% of the overall cost: maternal admission accounted for 57% and neonatal admission for 20%. Prenatal care represented 18% of the overall cost and 75% of overall acts. The average overall cost was 5,815€ for cesarean sections, 4,064€ for vaginal instrumented deliveries and 3,682€ for vaginal non-instrumented deliveries (p < 0.001). The regression model explained 45.5% of the cost variability. The incremental cost of a delivery through cesarean section was 955€ (an increase of 31.9%) compared with an increase of 193€ (6.4%) for an instrumented vaginal delivery. The incremental cost of admitting the newborn to hospital ranged from 420€ (14.0%) to 1,951€ (65.2%) depending on the newborn's severity. Age, origin and prenatal care were not statistically significant or economically relevant.

Conclusions

Neither immigration nor prenatal care were associated with a substantial difference in costs. The most important predictors of cost were delivery type and neonatal severity. Given the impact of cesarean sections on the overall cost of childbirth, attempts should be made to take into account its higher cost in the decision of performing a cesarean section.

Labor and delivery complications among teenage mothers

A broad set of academic literatures shows that childbearing is associated with a variety of negative health outcomes for teenage mothers. Many researchers question whether teenage childbearing is the causal explanation for the negative outcomes (i.e., whether there is a biological effect of teenage childbearing or whether the relationship is due to other factors correlated with health and teenage childbearing). This study investigates the relationship between teenage childbearing and labor and delivery complications using a panel of confidential birth certificate data over the period from 1994 to 2003 from the state of Texas. Findings show that compared to mothers aged 25 to 29 having their first child, teenager mothers appear to have superior health in most--but not all--labor and delivery outcomes.

Prenatal care utilization for mothers from low-income areas of New Mexico, 1989-1999

BACKGROUND

Prenatal care is considered to be an important component of primary health care. Our study compared prenatal care utilization and rates of adverse birth outcomes for mothers from low- and higher-income areas of New Mexico between 1989 and 1999.

METHODOLOGY/PRINCIPAL FINDINGS

Prenatal care indicators included the number of prenatal care visits and the first month of prenatal care. Birth outcome indicators included low birth weight, premature birth, and births linked with death certificates. The results of our study indicated that mothers from low-income areas started their prenatal care significantly later in their pregnancies between 1989 and 1999, and had significantly fewer prenatal visits between 1989 and 1997. For the most part, there were not significant differences in birth outcome indicators between income groupings.

CONCLUSIONS/SIGNIFICANCE

These findings suggest that while mothers from low-income areas received lower levels of prenatal care, they did not experience a higher level of adverse birth outcomes.

Evaluation of the impact of the Mother and Infant Health Project in Ukraine

This paper exploits a unique opportunity to evaluate the impact of the quality change in the labor and delivery services brought about by the Mother and Infant Health Project in Ukraine. Employing program evaluation methods, we find that the administrative units participating in the Project have exhibited greater improvements in both maternal and infant health compared to the control ones. Among the infant health characteristics, the MIHP impact is most pronounced for infant mortality resulting from deviations in perinatal period. As for the maternal health, the MIHP is the most effective at combating anemia, blood circulation and urinary-genital system complications, and late toxicosis. The analysis suggests that the effects are due to early attendance of antenatal clinics, lower share of C-sections, and greater share of normal deliveries. Preliminary cost-effectiveness analysis shows enormous benefit per dollar spent on the project: the cost to benefit ratio is one to 97 taking into account both maternal and infant lives saved as well as cost savings due to the changes in labor and delivery practices.

Effects of prenatal care on maternal postpartum behaviors

Most research on the effectiveness of prenatal care has focused on birth outcomes and has found small or no effects. It is possible, however, that prenatal care is "too little too late" to improve pregnancy outcomes in the aggregate, but that it increases the use of pediatric health care or improves maternal health-related parenting practices and, ultimately, child health. We use data from the Fragile Families and Child Wellbeing birth cohort study that have been augmented with hospital medical record data to estimate effects of prenatal care timing on pediatric health care utilization and health-related parenting behaviors during the first year of the child's life. We focus on maternal postpartum smoking, preventive health care visits for the child, and breastfeeding. We use a multi-pronged approach to address the potential endogeneity of the timing of prenatal care. We find that first trimester prenatal care appears to decrease maternal postpartum smoking by about 5 percentage points and increase the likelihood of 4 or more well-baby visits by about 1 percentage point, and that it may also have a positive effect on breastfeeding. These findings suggest that there are benefits to standard prenatal care that are generally not considered in evaluations of prenatal care programs and interventions.

Application of the Kessner and Kotelchuck prenatal care adequacy indices in a preterm birth population

OBJECTIVES

Healthy People 2010 goals to eliminate racial and ethnic health disparities that persist in the utilization of prenatal care (PNC) highlight the importance of measuring PNC as a variable in maternal and infant health outcomes research. These disparities are significantly correlated to adverse infant outcomes in preterm birth (PTB), a leading cause of infant mortality and life-long morbidity. Currently the most extensively used PNC adequacy indices (Kessner and Kotelchuck) were developed to measure outcomes in populations consisting mostly of full-term births. It is unclear whether these PNC adequacy indices are reliable when pregnancy is truncated due to PTB (<37 weeks). This paper compares and demonstrates how they can be applied in a specific PTB cohort.

DESIGN AND SAMPLE

This secondary analysis of a nested case-control study compares Kessner and Kotelchuck adequacy scores of 367 mothers of PTB infants.

RESULTS

There were significant differences in the rating of PNC inadequacy ( p<.001) depending on the PNC adequacy index used.

CONCLUSION

Critical evaluation is warranted before using these PNC adequacy indices in future public health nursing and PTB research.
