Health insurance coverage-enrollment and adequacy of prenatal care utilization.

Most studies have concluded that good prenatal care plays an essential role in improving birth outcomes, and numerous reports have documented barriers to adequate prenatal care. The relationship between health care insurance eligibility and enrollment procedures and adequacy of prenatal care, however, has not been suitably investigated. This study used data from a statewide representative sample of recently delivered women in South Carolina to assess (1) patterns of health care insurance source and (2) the independent effects of Medicaid enrollment and application procedures on receipt of prenatal care. Health insurance during pregnancy varied by sociodemographic characteristics. Black women's experiences with Medicaid enrollment and application procedures were associated with less than adequate prenatal care. Programmatic efforts and policies should emphasize further improvement in the systems of health care access and delivery to disadvantaged women.     

Barriers to the utilization of maternal health care in rural Mali

This study used data from the 2001 Demographic and Health Survey and multilevel logistic regression models to examine area- and individual-level barriers to the utilization of maternal health services in rural Mali. The analysis highlights a range of area-level influences on the use made of maternal health services. While the dearth of health facilities was a barrier to receipt of prenatal care in the first trimester, transportation barriers were more important for four or more prenatal visits, and distance barriers for delivery assistance by trained medical personnel and institutional delivery. Women's odds of utilizing maternal health services were strongly influenced by the practices of others in their areas of residence and by living in close proximity to people with secondary or higher education. Household poverty and personal problems were negatively related to all outcomes considered. The results highlight the importance of antenatal care and counseling about pregnancy complications for increasing the likelihood of appropriate delivery care, particularly among women living 15-29 km from a health facility. Area-level factors explained a greater proportion of the variation in delivery care than in prenatal care However, significant area variation in the utilization of maternal health services remained unexplained.     

Mexican-Americans' use of prenatal care and its relationship to maternal risk factors and pregnancy outcome.

We evaluate the adequacy of prenatal care use and the association of use to a series of maternal risk factors and pregnancy outcomes, such as low birthweight, preterm delivery, and macrosomia in both Mexican-Americans and non-Hispanic whites in Arizona. The data came from all live-birth certificates from 1986 and 1987 for a total of 101,202 (26,826 Mexican-Americans). We evaluated the adequacy of prenatal care using a redesigned index that accounts for three factors: the month when prenatal care began, the number of prenatal care visits, and the duration of pregnancy. From this index we identified six prenatal care groups: intensive, adequate, intermediate, inadequate, no-care, and missing/unknown. Overall, we observed ethnic differences in patterns of prenatal care use, social profiles, and medical risk factors. Non-Hispanic whites, compared to Mexican-Americans, showed a greater risk for low birthweight and preterm delivery in those groups receiving poor prenatal care versus those who received adequate care. Within Mexican-Americans the risk of low birthweight was not the same for all subgroups. A higher overall prevalence of preterm delivery and macrosomia in comparison to low birthweight occurred in Mexican-Americans. We discuss the implications of the results for the identification, interpretation, evaluation, and public health significance of perinatal health problems of Mexican-Americans.     

The effects of variations in AFDC and Medicaid eligibility on prenatal care use.

Despite substantial evidence linking improved pregnancy outcomes with receipt of prenatal care and recent improvements in prenatal care utilization, specific subpopulations continue to receive less than adequate care. The study reported here examined the effects on prenatal care utilization of differences among states in AFDC and Medicaid eligibility policies. The study was based on information obtained from birth certificates and a mailed questionnaire to stratified random samples of all women experiencing live births during specified periods in four states. States were selected to provide comparisons between two states with liberal AFDC and Medicaid eligibility standards--Wisconsin and Colorado--and two states--Maine and Texas--which had more restrictive standards at the time data were collected. Study findings generally indicate that more liberal AFDC/Medicaid eligibility standards improve the adequacy of prenatal care among low income women. They also suggest, however, that the often lengthy eligibility process may actually pose barriers to care.     

Barriers to Prenatal Care for Mexican and Mexican American Women

Despite the presumed health benefits, Latinas are less likely than women from other ethnic groups to receive adequate prenatal care during their pregnancy. However, it is unclear whether this trend is the result of political economic conditions that limit access of many Latinos in the United States to adequate health services in general, or of sociocultural conditions that restrict the use of such services even when they are made available. Furthermore, it is unclear whether these barriers pose a risk for adverse birth outcomes in this population. To address these issues, we conducted a two-phase study of the political economic and sociocultural barriers to use of prenatal care services among Mexican and Mexican American women living in San Diego, California, and their association with adverse birth outcomes in this population. A quantitative assessment of information abstracted from the medical records of 173 Latinas who had given birth at a university medical center found that absence of Medi-Cal benefits or other forms of health insurance was the only significant predictor of inadequate prenatal care during pregnancy. However, neither lack of insurance nor adequate prenatal care was associated with any adverse birth outcomes. A qualitative analysis of information obtained from interviews of 30 Latinas receiving prenatal care services at a medical clinic for the homeless and medically underserved residents of San Diego identified three major themes underlying the lack of adequate prenatal care: lack of trust in formal versus informal institutions, wanted versus unwanted pregnancies, and the importance of the social network.     

A comparison of capitated and fee-for-service Medicaid reimbursement methods on pregnancy outcomes.

OBJECTIVE: To determine if the payment method influenced the likelihood of selected obstetrical process measures and pregnancy outcome indicators among Medicaid women. DATA SOURCE/STUDY SETTING: Data from the live birth certificates computer file for 1993 from the State of California. The computer files contain information about the demographic characteristics of the mother, her medical conditions prior to delivery, medical problems during labor and delivery, delivery method, newborn and maternal outcomes, and expected principal source of payment for prenatal care and for hospital delivery. STUDY DESIGN: The study sample consisted of singleton live births to women in the California Medi-Cal program residing in one of two counties in which a mixed-model managed care plan was the method of reimbursement or in one of three counties in which fee-for-service was the payment method. The study and control counties were matched in terms of geographic proximity and sociodemographics. PRINCIPAL FINDINGS: Among Medi-Cal women, the likelihood of low birth weight (LBW) was lower in the capitated payment group than in the fee-for-service payment group even when controlling for maternal and newborn characteristics and adequacy of prenatal care. There was no difference in either the adequacy of prenatal care, the cesarean birth rate, or the likelihood of adverse pregnancy outcomes other than LBW between the two payer groups. CONCLUSIONS: Results of this "natural experiment" suggest that enrollment of pregnant Medi-Cal beneficiaries in capitated healthcare services through a primary care case management system in a county-organized health system/health insuring organization can have a beneficial effect on low birth weight and provide care comparable to a fee-for-service system.     

Disparities in Pregnancy Healthcare Utilization Between Hispanic and Non-Hispanic White Women in Rhode Island

Low healthcare utilization is a prime contributor to adverse health outcomes in both the general population and the Hispanic community. This study compares background characteristics and rates of prenatal and postpartum health care utilization between Hispanic and non-Hispanic white women. Using the Rhode Island Pregnancy Risk Assessment Monitoring System (PRAMS), 2002?C2008, we assess rates of prenatal and postpartum healthcare utilization relevant to maternal and neonatal care. Associations between maternal ethnicity and adequacy of health care utilization were quantified using survey weighted multivariable logistic regression. Compared with non-Hispanic white women, Hispanic women were younger (less than 24?years, 43.8% vs. 25.2%), had less education (less than 12?years of education, 38.2% vs. 10.6%), lower annual income levels (incomes less than $19,999, 72.2% vs. 21.7%), and lower insurance rates before pregnancy (47.8% uninsured vs. 12.8%). Hispanic women had higher odds of having delayed prenatal care (AOR 1.84, 95% CI 1.27?C2.65) or inadequate prenatal care (AOR 2.01, 95% CI 1.61?C2.50), and their children had higher odds of not having a 1-week check-up (AOR 1.73, 95% CI 1.21?C2.47) or any well-baby care (AOR 3.44, 95% CI 1.65?C7.10). Disparities in inadequate prenatal care and not having any well-baby care remained significant after adjusting collectively for age, marital status, education, income, and insurance status of mother and newborn. Although many previously uninsured women became insured during pregnancy, disparities in healthcare utilization remained. Interventions focusing on reducing barriers to access prior to and during pregnancy should consider potential structural, informational, and educational barriers.     

Immigration legal status and use of public programs and prenatal care

This study assessed impacts of immigrants' legal status on utilization of prenatal care and public programs by non-citizen women. Interviews and chart reviews of 171 women were conducted less than 48 hours after delivery at an urban hospital. Among non-citizens, 67% were legally documented. No differences in prenatal care adequacy by legal status were detected among non-citizens, who as a group had less health insurance, worse socioeconomics, and less program use compared to U.S. citizens. Non-citizens also were less aware of newborn's citizenship and eligibility for public programs and benefits. Non-citizens utilized fewer programs while reporting greater economic hardship than citizens; however, non-citizens selectively used programs important for pregnancy. Given changes in eligibility for federal programs and high rates of reported food insecurity and socioeconomic hardship among non-citizens, monitoring for adverse effects on utilization of prenatal care and birth outcomes is needed.     

Prenatal care utilization: its measurement and relationship to pregnancy outcome

This study proposes a redesigned measure of prenatal care utilization based on modifications made to a preexisting index of the adequacy of such care. Six prenatal care utilization groups were delineated: intensive, adequate, intermediate, inadequate, no-care, and missing/unknown. Using 430,349 cases from South Carolina and North Carolina vital records from 1978 to 1982 (live birth-infant death cohort files for white resident mothers), this proposed prenatal care utilization measure was examined by maternal sociomedical risk characteristics (age-parity, marital status, education, complications of pregnancy, and previous pregnancy terminations) and by pregnancy outcomes (birth weight, gestational age, and birth weight- and gestational age-specific neonatal mortality). The intensive prenatal care group had relatively more pregnancy complications but also the most preferred pregnancy outcomes. Appreciable differences in birth weight and gestational age distributions were observed among the prenatal care categories within maternal risk status groups. Increased utilization of prenatal care was associated with higher mean birth weight and gestational age. However, after controlling for maternal risk status, an appreciable variation in birth weight- and gestational age-specific neonatal mortality was not apparent across prenatal care groups.     

Barriers to prenatal care in Europe.

BACKGROUND: In Europe, it is sometimes assumed that few barriers to prenatal care exist because extensive programs of health insurance and initiatives to promote participation in prenatal care have been established for many decades. METHODS: A case-control study was performed in ten European countries (Austria, Denmark, Germany, Greece, Hungary, Ireland, Italy, Portugal, Spain, and Sweden). Postpartum interviews were conducted between 1995 and 1996. A total of 1283 women with inadequate prenatal care (i.e., with 0, 1, or 2 prenatal care visits or a first prenatal care visit after 15 completed weeks of pregnancy) and 1280 controls with adequate prenatal care were included in the analysis combining data from the ten countries. RESULTS: Based on combined data of the ten countries, lack of health insurance was found to be an important risk factor for inadequate prenatal care (crude odds ratio [OR] at 95% confidence interval [CI]: 30.1 [20.1-47.1]). Women with inadequate prenatal care were more likely to be aged < 20 years (16.4% vs 4.8%) and with higher parity (number of children previously borne) than controls. They were more likely to be foreign nationals, unmarried, and with an unplanned pregnancy. Women with inadequate care were also more likely to have less education and no regular income. They had more difficulties dealing with health services organization and child care. Cultural and financial barriers were present, but after adjusting for confounders by logistic regression, perceived financial difficulty was not a significant factor for inadequate prenatal care (adjusted OR [95% CI]: 0.7 [0.4-1.3]). CONCLUSIONS: Personal, socioeconomic, organizational, and cultural barriers to prenatal care exist in Europe.     

Initiation of prenatal care by low-income Hispanic women in Houston.

OBJECTIVE: To understand why many Hispanic women begin prenatal care in the later stages of pregnancy. METHODS: The authors compared the demographic profile, insurance status, and health beliefs--including the perceived benefits of and barriers to initiating prenatal care--of low-income Hispanic women who initiated prenatal care at different times during pregnancy or received no prenatal care. RESULTS: A perception of many barriers to care was associated with later initiation of care and non-use of care. Perceiving more benefits of care for the baby was associated with earlier initiation of care, as was having an eligibility card for hospital district services. Several barriers to care were mentioned by women on open-ended questioning, including long waiting times, embarrassment the physical examination, and lack of transportation. CONCLUSIONS: Recommendations for practice included decreasing the number of visits for women at low risk for poor pregnancy outcomes while increasing the time spent with the provider at each visit, decreasing the number of vaginal examinations for low risk women, increasing the use of midwives, training lay workers to do risk assessment, emphasizing specific messages about benefits to the baby, and increasing general health motivation to seek preventive care through community interventions.     

Barriers and motivators to prenatal care among low-income women

Substantial evidence exists which links prenatal care to improved birth outcomes. However, low-income and nonwhite women in the United States, who are at greatest risk for poor birth outcomes, continue to receive the poorest prenatal care. The purpose of this study was to identify and compare barriers and motivators to prenatal care among women who lived in low-income census tracts. The stratified sample included recently delivered white, black and American Indian women who received adequate, intermediate, and inadequate prenatal care. Interviews were conducted which focused primarily on the women's perceptions of problems in obtaining prenatal care and getting to appointments. Results indicated that women with inadequate care identified a greater number of barriers and perceived them as more severe. Psychosocial, structural, and socio-demographic factors were the major barriers, while the mother's beliefs and support from others were important motivators. The predictive power of selected barrier variables was examined by a regression analysis. These variables accounted for 50% of the variance in prenatal care use. The results affirm the complexity of prenatal care participation behavior among low-income women and the dominant influence of psychosocial factors. Comprehensive, coordinated and multidisciplinary outreach and services which address psychosocial and structural barriers are needed to improve prenatal care for low-income women.     

Source of bias in prenatal care utilization indices: implications for evaluating the Medicaid expansion.

BACKGROUND: Recent expansions in eligibility for coverage of prenatal care services by the Medicaid program reflect national initiatives to improve pregnancy outcomes. This study investigates the potential impact that completeness of reporting of prenatal care and gestational age variables and strategies to impute missing data may have on evaluations of the Medicaid expansion. METHODS: This study, examining 15 years of vital record data from a single state and comparing 1 year of data from four mid-Atlantic states, selected single live births to resident mothers for analyses. The "day 15" and the "preceding case" methods were used to impute missing gestational age data. RESULTS: Considerable temporal and geographic variation was detected in completeness of reporting of variables used to construct prenatal care indices. After imputing values for cases with missing data, the proportion of cases for which adequacy of prenatal care utilization could not be determined ranged from 3% to 24% among the states investigated. For those cases where gestational age data could be imputed, the distribution of prenatal care utilization was not markedly disparate from those cases with complete reporting of gestational age. CONCLUSIONS: The results indicate that variations in reporting, decisions regarding the treatment of missing data, and the choice of the denominator can alter prenatal care utilization percentages and have implications for evaluations of the impact of the recent Medicaid expansion on prenatal care utilization.     

Predictors of prenatal care utilization

Despite substantial evidence linking improved pregnancy outcomes with receipt of prenatal care and recent improvements in prenatal care utilization, specific subpopulations continue to receive inadequate or less than adequate care. The study reported here examined the predictive power of a set of variables describing the type of financial coverage available to the mother, attributes of the mother, father and family and characteristics of the health care system. A stratified random sample of mothers was generated from state birth certificate files and surveyed through the use of a mailed questionnaire. Stratification was designed to assure adequate representation of subgroups expected to receive less adequate prenatal care. The study findings indicate that there were deficiencies in prenatal care utilization and that these deficiencies were concentrated in specific areas and subpopulations within the state. While the majority of women in the study started prenatal care in the recommended first trimester, most did not maintain the recommended schedule of visits with their care provider. The following conditions were found to reduce the likelihood of receiving adequate care after controlling for service need: younger women (particularly adolescents); less educated (particularly those without a high school education); low income; longer travel time; Medicaid recipient; and rural resident. In addition, it was found that where one lives is a significant predictor of the adequacy of prenatal care even after controlling for all of the above variables. The authors conclude that it is important in assessing potential policy and program options for reducing differentials in prenatal care use to distinguish between economic and noneconomic barriers to utilization. Receipt of Medicaid does not assure adequate prenatal care use.(ABSTRACT TRUNCATED AT 250 WORDS)     

Drawing women into prenatal care

Participation in prenatal care services in the United States is low relative to that in many other developed countries, and rates of use are declining among some high risk groups. In 1986, 18 percent of all U.S. infants were born to women who delayed care until the second trimester of pregnancy; four percent, to women who initiated care in the third trimester; and about two percent, to women who obtained no prenatal care at all. Among the major barriers to prenatal care are inadequate insurance coverage, limitations in the Medicaid program, inadequate capacity in the maternity care system, lack of coordination between health and social services for low-income women and inhospitable conditions at some sites where prenatal care is delivered. The personal beliefs, knowledge, attitudes, fears and lifestyles of some pregnant women also constitute obstacles to care. For example, having an unwanted pregnancy, attaching little value to prenatal care and having a tenuous connection to the health care system in general are important predictors of insufficient care. Encouraging universal participation in prenatal care will require a major overhaul of the maternity care system. However, while consensus for fundamental reform builds, several immediate steps should be taken--such as reducing financial barriers to care; expanding the capacity of the maternity care system; improving the policies and practices that shape prenatal services at the site where they are delivered; and increasing public information.     

Maternal obesity and glucose intolerance during pregnancy among Mexican-Americans

Low birthweight is uncommon among Mexican-American infants, despite the substantial proportion of mothers who live in poverty. This apparent paradox has generated studies of factors protecting fetal growth, but may have masked other important health problems in the Mexican-American community. Obesity, impaired glucose tolerance and diabetes are common among Mexican-American women of childbearing age and during pregnancy. Prevalence of these conditions is two to four times higher in Mexican-American than in non-Hispanic white women. As obesity and glucose intolerance during pregnancy are associated with fetal overgrowth and increased risk of subsequent obesity and type 2 diabetes in mother and child, the adequacy of birthweight as a measure of maternal and infant risk may be obscured in populations with a high prevalence of these conditions. Their possible contribution to the increasing incidence of obesity and type 2 diabetes in Mexican-American children, adolescents and young adults has not been examined. Appropriate preconception, prenatal and follow-up care may identify high-risk women, improve weight and metabolic status and reduce the severity and impact of diabetes and its complications. However, late or no prenatal care is common among Mexican-American women and the frequency of follow-up care is unknown. As low birthweight is a major public health indicator of maternal and neonatal health, perceived 'good birth outcomes' have reduced health policy, programme and research attention to Mexican-American mothers and infants. Studies of the impact of obesity and glucose intolerance during pregnancy on the birthweights of Mexican-American infants should be undertaken, along with systematic assessment of the subsequent health status and preventive health-care needs of women and children in this population.     

Severity, manifestations, and consequences of violence among pregnant adolescents.

PURPOSE: To examine the severity, manifestations, and consequences of prenatal violence among adolescent and adult participants in a county health department prenatal care coordination program. METHODS: The prospective cohort study design included all Medicaid-eligible program participants from 1994 to 1996. Care coordinators screened participants for prenatal violence using a validated, systematic violence assessment protocol at three times during pregnancy. This protocol was linked with prenatal care and hospital delivery records to document pregnancy outcomes. The main outcome variables were low birth weight (<2500 g) and preterm delivery (before 37 weeks' gestation). RESULTS: Among teens, 16.1% reported prenatal violence, including 9.4% who reported severe violence such as hitting, kicking, or stabbing. Among adults, 11.6% reported prenatal violence, including 4.8% who reported severe violence. Teens were more likely than adults to report abdominal trauma (56% vs. 22%) and violence perpetrated by a relative (23% vs. 5%). Teens who reported severe prenatal violence were more likely to report alcohol use. They were significantly more likely to deliver preterm than teens who reported "other" or "no" prenatal violence (odds ratio 3.5, 95% confidence interval 1.1-10.8) when adjusting for race, adequacy of prenatal care, prior preterm delivery, and alcohol use. For adults, the relationship between prenatal violence and preterm delivery was not statistically significant. The relationship between prenatal violence and low birth weight was not significant for either age cohort. CONCLUSIONS: Prenatal violence was a significant risk factor for preterm birth in this population, especially among teens.     

Psychopathology Symptoms are Associated with Prenatal Health Practices in Pregnant Women with Heavy Smoking Levels

Purpose

Smoking during pregnancy may be linked to other problematic prenatal health behaviors in women. We examined interrelationships among prenatal smoking, prenatal health behaviors and mental health. The objective of this study was to examine factors that may contribute to variations in prenatal health practices among women who smoke during pregnancy.

Methods

Birth mothers from an adoption study (N?=?912) were interviewed about prenatal smoking, health behaviors, and mental health symptoms at 5 months postpartum.

Results

One-quarter of participants (N?=?222) reported smoking 6 or more cigarettes daily for at least 1 trimester. For mothers who smoked more than 6 cigarettes daily, higher levels of antisocial behaviors (β?=????.14, p?=?.03) and depressive symptoms (β?=????.17, p?=?.03) were associated with less frequent prenatal folate use; antisocial behaviors and depressive symptoms were not associated for prenatal folate use among women who did not smoke more than 6 cigarettes daily. For mothers who did not smoke more than 6 cigarettes daily, more depressive symptoms were associated with fewer prenatal care visits (β?=?.12, p?=?.01). Antisocial behaviors and anxiety symptoms were not associated with prenatal care visits in either group of mothers.

Conclusions for Practice

Maternal antisocial behaviors and depressive symptoms during pregnancy may be markers for poorer adherence to recommendations for folate supplementation among women who smoke 6 or more cigarettes daily during pregnancy, independent of adequacy of prenatal care.
