Pregnancy wantedness and the early initiation of prenatal care.

The study examines the impact of the wantedness of a pregnancy on the demand for early prenatal care. Using a cohort of pregnant women in New York City, we estimate a prenatal care demand function in which we control for the probability of giving birth, given a woman is pregnant. We interpret this control as a measure of wantedness. The results indicate that if the black and Hispanic women who aborted had instead given birth, they would have delayed the initiation of prenatal care, on average, more than three-quarters of a month longer than the mean number of months of delay that were actually observed for the women who gave birth. By allowing women to terminate an unwanted pregnancy, induced abortion increases the average use of prenatal care among black and Hispanic women relative to what would have been observed if the women who aborted had instead given birth.

Prenatal care utilization in Hawaii: did it improve during the last 16 years?

This paper examines the utilization of prenatal care in Hawaii from 1979 to 1994 to determine if early and adequate utilization of prenatal care has changed during this period. Birth certificates of single live born infants of resident women were the source of data for the study. During the study period, the proportion of women receiving prenatal care in the first trimester increased by nearly 5 percent but was still below the national and state Year 2000 health objective of 90 percent. Notwithstanding this improvement, the percentage of women who did not receive the recommended number of visits in spite of starting care early significantly increased. The overall proportion of women with 'intensive' prenatal care use markedly increased (134.7%). The proportion of women with 'inadequate' care use declined (10.3%), although the proportion of women with 'no care' use doubled. Complete reporting of use of care through birth certificates markedly deteriorated. The findings of this study indicate the need for changes in the targeting and provision of counseling and education on the part of health care providers. Public health leaders, policy makers, health care providers, and advocacy groups need to collectively review programmatic directions with an aim toward the development of innovative approaches to address the emerging health needs of mothers and infants in the state.

Birth outcomes and the effectiveness of prenatal care.

OBJECTIVE: To investigate pregnant women's self-selection effects on the estimation of birthweight production function. A particular emphasis is placed on assessing the effectiveness of prenatal care as a major medical input in the birthweight production function. DATA SOURCES: Primary data compiled from birth and abortion certificates for the Commonwealth of Virginia in 1984. Several area-specific socioeconomic variables were also employed from the Area Resource File 1984; Supplemental Food Program for Women, Infants, and Children (WIC) Local Agency Directory; and the family planning clinics data by the Alan Guttmacher Institute (AGI). STUDY DESIGN: Two types of self-selection effects are defined: selection effect due to sample censoring from the resolution of pregnancies as live births or induced abortions; and selection effect due to the use of prenatal care as an endogenous variable. Race- and location-specific birthweight production functions are estimated using models with and without correction for self-selection effects. PRINCIPAL FINDINGS: The self-selection effect in the resolution of pregnancies is race-specific, being significant for African American women. The effectiveness of prenatal care in birthweight production is underestimated substantially by the selection bias from the use of prenatal care, and overestimated by the selection bias from pregnancy resolutions. On average, the overall estimated effectiveness of prenatal care is over five times higher after controlling for the selection effects. CONCLUSIONS: Self-selection effects could be a very serious problem in measuring the effectiveness of birthweight determinants in general. The overall effectiveness of prenatal care, in particular, tends to be significantly biased downward without controlling for selection effects. The significance and scale of the bias depends crucially on specific data and cohorts of the population investigated.

Perceived impediments to prenatal care among low-income women.

The study describes women's experience with prenatal care, their perceived impediments to care, and compares the impediments cited by the women with levels of care utilization. The sample consisted of 126 African American women. A structured interview and questionnaire were used. The results showed that pregnancy was unplanned in 78.6% of the women, and no one encouraged the women to obtain care in half the cases. Only 50.8% of the women made adequate utilization of prenatal care. The main impediments to care were transportation, long waiting time, having too many other problems, and fear of staff finding out about the women's use of substances. Five of the reported impediments significantly influenced the women's utilization of care. These were: substance abuse, fear of medical examination, the belief that prenatal care is not necessary, already knew of pregnancy, and no babysitter for other children.

Inadequate syphilis screening among women with prenatal care in a community with a high syphilis incidence.

OBJECTIVES AND GOAL: This study was designed to evaluate the extent to which pregnant women in a community with a high syphilis incidence were screened for syphilis according to standard recommendations of twice during prenatal care and at labor and delivery. STUDY DESIGN: Labor and delivery records from 4 hospitals in Miami-Dade County, Florida, were abstracted to obtain maternal and prenatal care characteristics and syphilis screening practices. RESULTS: Of the 1991 women, records indicated that 1655 (83%) were screened at least once during prenatal care, 220 (11%) were screened twice during prenatal care before delivery, and 184 (9%) were screened twice during prenatal care and at delivery. Attending a private clinic, having more than adequate prenatal care and having private insurance were associated with not being screened at least twice before delivery. CONCLUSIONS: Few women were screened according to standard recommendations, and provider or institutional-related factors affected adequacy of screening.

Retinopathy of prematurity: lack of association with prenatal care.

OBJECTIVES: The overall goal of this study was to prospectively assess risk factors for retinopathy of prematurity (ROP) in infants of birth weight <1250 g in an urban population at Bellevue Hospital Center, New York, New York. The hypothesis tested was that lack of prenatal care increases the incidence of ROP. METHODS: A consecutive sample of patients admitted to Bellevue Hospital Center's neonatal intensive care unit/special care nursery who weighed <1250 g at birth and survived until their ophthalmology screening examinations were included in the study. The main outcome measures were presence or absence of ROP and prenatal care. Additional relevant clinical information was collected on the patients. RESULTS: Ninety infants were evaluated. Sixty-one (68%) had ROP; 29 (32%) had no ROP. No differences in incidence or severity of ROP were detected with regard to prenatal care when the 2 groups were compared. In this population <1250 g, there were no differences in birth weight or gestational age with respect to prenatal care or lack of prenatal care. CONCLUSIONS: Lack of prenatal care was not associated with an increased risk for ROP in infants with birth weight <1250 g in this urban population.

The impact of prenatal care on the outcome of pregnancy.

In a 12-months' prospective project all women delivering at the Soroka Medical Center, Beer-Sheba, Israel, were studied with regard to the type of prenatal care (P.C.) and the outcome of pregnancy. The Soroka Medical Center is the sole medical facility providing obstetric and neonatal services to the 300,000 inhabitants of the region. Prenatal care is delivered by a uniform network of 70 community-based stations. The availability, type and quality of services were uniform for all women and were not altered throughout the study period. The project encompassed 7308 deliveries. 2154 Bedouin women were excluded in order to avoid possible bias due to cultural and genetic characteristics. Data regarding 5154 Jewish women were analysed. Perinatal mortality was inversely proportional to the number of prenatal contacts. The uncorrected mortality rates were 12.7% in women entirely lacking P.C. and 6.2%, 1.9% and 1.0% in patients who had 1-6, 7-10 and 11 or more prenatal contacts respectively. The low-birthweight rate was significantly increased in women lacking prenatal care (22.8%) or having rudimentary care (17.4%) as compared to those who had 11 or more prenatal contacts with medical personnel (5.9%). Prenatal care reduced neonatal morbidity as expressed by the length of hospitalization, the frequency of infants with multiple diagnoses and the incidence of specific pathologies such as respiratory distress syndrome, light for dates and asphyxia. The incidence of some complications of pregnancy (abruptio placentae, premature labor, PROM) was significantly increased in women lacking P.C. or having inadequate P.C. (1-6 prenatal contacts). Moreover, lack of prenatal care was clearly connected with high-risk delivery, thus increasing the danger to the baby. It is suggested that many adverse effects of various socio-economic, genetic and general health factors may be diminished by proper prenatal care coupled with adequate obstetric and neonatal services.

Impact of prenatal care on infant survival in Bangladesh.

Despite improvements in public health in recent decades, levels of infant and child mortality remain unacceptably high, particularly in developing countries where primary healthcare services including prenatal care services are not universally available. Using information on 7,001 childbirths in five years preceding the 2004 Bangladesh Demographic and Health Survey, this study examined the relationship between receiving prenatal care during pregnancy and infant mortality using multivariate survival analysis. The results are presented in hazard ratios (HR) with 95% confidence intervals (95% CI). Results indicate that children of mothers who did not receive prenatal care during pregnancy were more than twice as likely to die during infancy as children whose mothers received prenatal care during pregnancy (HR=2.40, 95% CI: 1.74, 3.31) independent of child's sex, delivery assistance, birth order; mother's age at child birth, nutritional status, education level; household living conditions, and other factors. Children born to older mothers living in households without safe drinking water were at an increased risk. The study concludes that prenatal care is strongly negatively associated with infant mortality in Bangladesh independent of other risk factors. The results suggest that improving prenatal care services at the community level is key to improving child survival in Bangladesh.

[Evaluation of the prenatal care program in Curitiba, Paraná, Brazil: a cohort study of primigravidae].

A prenatal care program was evaluated to measure its effectiveness and impact. In 1999 a new prenatal care program was introduced in Curitiba, Paraná State, Brazil, in health services under the Unified National Health System, introducing organizational changes in order to enhance accessibility, increase the number and distribution of prenatal visits, and ensure minimum necessary procedures. To evaluate how these changes were assimilated in routine practice, a cohort study was proposed in a sample of 660 primigravidae randomly selected among women enrolled in the program before the 20th week of gestation, from March to August, 2000. Two home visits and consultation of maternity cards or patient records during prenatal and hospital care were performed. The results indicate good accessibility and professional adherence to the protocol, but problems still remain with initiating care before the end of the first trimester and adequate distribution of consultations. According to the study criteria, adequate care was found for only 38.6% of the women, pointing to the complexity of factors that influence adequate prenatal care.

Poverty, prenatal care, and infant health in Puerto Rico.

Using data from a survey administered to a representative sample of mothers who gave birth in Puerto Rico in 1994-95, we investigate whether prenatal care and infant health outcomes are associated with family poverty and neighborhood poverty. The results show that infant health outcomes are unrelated to both family poverty and neighborhood poverty, despite the association of family poverty with the adequacy of prenatal care and the content of prenatal care. However, the poverty paradigm does receive some support using measures of participation in government programs that serve the low-income population. Women who rely on the government to fund their medical care are more likely than women who rely on private health insurance to have an infant death. They are also less likely to receive the highest levels of prenatal care. Nonetheless, targeted government programs can have an ameliorative impact. The analysis shows that participants in the Women, Infants, and Children (WIC) program are more likely than non-participants to receive superior levels of prenatal care and are less likely to have negative infant health outcomes.

Sources of prenatal care data and their association with birth outcomes of HIV-infected women.

OBJECTIVES: Different sources of prenatal care data were used to examine the association between birth outcomes of HIV-infected women and the Adequacy of Prenatal Care Utilization (APNCU) index. METHODS: Adjusted odds ratios of birth outcomes for 1858 HIV-positive mothers were calculated for APNCU indexes on the basis of birth certificate data or 3 types of physician visits on Medicaid claims. RESULTS: Claims- and birth certificate-based APNCU indexes agreed poorly (kappa < 0.3). Only the broadest claims-based APNCU index had lower adjusted odds ratios for low birthweight (0.64; 95% confidence interval [CI] = 0.49, 0.84) and preterm birth (0.70; 95% CI = 0.54, 0.91). The birth certificate-based index had a reduced adjusted odds ratio (0.73; 95% CI = 0.56, 0.95) only for preterm birth. CONCLUSIONS: The association of birth outcomes and adequacy of prenatal care in this HIV-infected cohort differed significantly depending on the source of prenatal care data.

Sociodemographic factors and the quality of prenatal care.

BACKGROUND: In this study, maternal sociodemographic factors are examined in relationship to the quality of prenatal health services US women receive. METHODS: Data from the 1980 National Natality Survey and 1980 Fetal Mortality Survey were used for the analysis. Indicator variables for prenatal care quality are the percentages of prenatal visits at which blood pressure and urine were tested, the performance of hemoglobin or hematocrit tests, and the presence or absence of advice regarding salt restriction and diuretics usage during pregnancy. RESULTS: Distribution of the basic examinations in prenatal care vary according to marital status, parity, education, and residence in a metropolitan or nonmetropolitan county. The advice received concerning salt and diuretics usage was also influenced by sociodemographic variables. CONCLUSIONS: The analyses reveal that prenatal care is not of even minimally acceptable quality for many women.

The perinatal and economic impact of prenatal care in a low-socioeconomic population.

Reductions in publicly funded prenatal care programs in 1981 to 1984 resulted in an increase in unregistered patient deliveries from 7.8% to 14.9% of births at University of California San Diego Medical Center. To assess the economic and perinatal impact of the increasing number of deliveries of women without prenatal care, 100 consecutive patients with fewer than three prenatal visits were studied. Each "no care" patient was matched by age, parity, and week of delivery with a control patient who received care in a state-funded perinatal project (Comprehensive Perinatal Program). Maternal antenatal risk factors were equally distributed between the two groups when maternal age, parity, history of substance abuse, prior preterm delivery, hypertension, and abortion were compared. Maternal obstetric outcomes were similar, including cesarean section rate and incidence of postpartum fever and hemorrhage. However, neonates delivered of women receiving no care experienced significantly greater morbidity than the neonates of women in the Comprehensive Perinatal Program, including an increased incidence of premature rupture of the membranes and preterm delivery (13% versus 2%, p less than 0.05), low birth weight (21% versus 6% less than 2500 gm, p less than 0.002), and intensive care unit admissions (24% versus 10%, p less than 0.005). When the total inpatient hospital charges were tabulated for each mother-baby pair, the cost of perinatal care for the group receiving no care ($5168 per pair) was significantly higher than the cost for patients in the Comprehensive Perinatal Program ($2974 per pair, p less than 0.001) including an antenatal charge of $600 in the Comprehensive Perinatal Program. The excess cost for delivery of 400 women receiving no care per year in the study hospital was $877,600. These results suggest that extension of prenatal care programs to medically indigent women is likely to result in a net reduction in perinatal morbidity and health care expenditures.

Pregnancy intentions, pregnancy attitudes, and the use of prenatal care in Missouri.

OBJECTIVES: This study uses data from 2378 mothers of live-born infants from the NICHD/Missouri Maternal and Infant Health Survey to examine the relationship between pregnancy intention and adequacy of prenatal care. METHODS: Pregnancy intention was measured using traditional classifications of mistimed and unwanted pregnancies as well as additional measures of women's attitudes about their pregnancies. Odds ratios for inadequate prenatal care and its component parts (initiation of care and receipt of services) were calculated using multiple logistic regression in separate models and in a combined model for the measures of intention and attitude. RESULTS: Women's attitudes about their pregnancies were associated with inadequate prenatal care, including both inadequate initiation of care and inadequate receipt of services. Traditional measures of intendedness were significantly related only to inadequate initiation of care. Women who were unhappy about the pregnancy (OR = 1.44), unsure that they wanted to be pregnant (OR = 2.81), or denied their pregnancies (OR = 4.82) were more likely to have inadequate prenatal care than women who did not have these attitudes. Women who were unhappy about being pregnant (OR = 1.86), unsure that they wanted to be pregnant (OR = 3.44), or who denied the pregnancy (OR = 6.69) were more likely to have inadequate initiation of care. Women who were unsure that they wanted to be pregnant (OR = 1.95) or who denied their pregnancies (OR = 2.47) were more likely to have received inadequate care once they had entered care. CONCLUSIONS: This study suggests that attitudes about pregnancy may be a psychosocial barrier to women obtaining early and continuous prenatal care. Pregnancy attitudes should be assessed and appropriate services provided to improve women's utilization of prenatal care. New measures of pregnancy attitude, beyond the traditional intention measures, can be useful in assessing pregnancy wantedness and identifying women to target for these services.

Racial differences in late prenatal care visits.

The purpose of this study was to examine potential racial disparities in the use of prenatal care beyond what could be measured by the Kessner Index. The data were obtained from the 1986 Massachusetts Prenatal Care Survey, a follow-back study of 2587 postpartum women, which had as its primary objective the identification of barriers to adequate use of prenatal care. This investigation examined the number of prenatal visits reported for each month of pregnancy and found that white women reported significantly more visits than black women only in the eighth and ninth months of pregnancy. This racial difference remained after we controlled for gestational age, sociodemographic factors, reported barriers to care, payor status, and access to care. This study suggests that racial differences in use of late prenatal visits need direct attention if the gaps in use of prenatal care and adverse birth outcomes are to be lessened.

[Assessment of prenatal care in pregnant women].

INTRODUCTION: The aim of Prenatal care of pregnant woman is to asses her general condition and as soon as possible all eventual complications associated with pregnancy. Only diagnoses of pathological states in early stages may allow to use prophylaxis and to treat it. OBJECTIVE: The purpose of this study is to asses prenatal care of pregnant women who delivered in Department of Obstetrics and Gynaecology Collegium Medicum of The Jagiellonian University. MATERIAL/METHODS: On the basis of questionnaire we analyzed 100 pregnant women, the average age was 27.6, and different socioeconomic status who delivered neonates in Department of Obstetrics and Gynaecology Collegium Medicum of The Jagiellonian University in 2002 year. RESULTS: Majority of patients were in the age range between 25 and 28 with middle education. 95.5% women underwent first obstetrical visit during first 3 months of the gestational age. The average number of obstetrical visits during pregnancy was 11. 69% women had one obstetrical visit per month. The average duration of visit was more than 20 minutes. 99% women underwent examinations for pregnancy induced hypertension, gestational diabetes mellitus and anemia. Ultrasound examination was performed in 99% women. In majority of cases women were not enough informed about birthing school, possibilities of administration of anesthesia during labour, family delivery and sexual intercourses during pregnancy. CONCLUSION: 1. This study suggests that pregnant women benefit from appropriate medical care during pregnancy. 2. Correctly performed screening for pregnancy induced hypertension, gestational diabetes mellitus and anemia allow to prevent pathology. 3. Pregnant women are not enough informed about possibilities of administration of anesthesia during labour, family delivery, birthing school and sexual intercourses during pregnancy.

Salvadoran fathers' attendance at prenatal care, delivery, and postpartum care.

OBJECTIVE: To provide a baseline perspective on the prevalence of Salvadoran men's attendance at prenatal care, delivery, and postpartum well-baby care and on sociodemographic factors associated with their attendance, with the goal of informing efforts to help men play more positive roles in maternal-child health. METHODS: The data came from the 2003 Salvadoran National Male Health Survey. The data focused on fathers (n = 418) and their most recent live-born child in the preceding five years. Factors associated with the fathers' participation in prenatal care visits, attendance at delivery, and participation in postnatal well-baby visits were explored using logistic and multinomial regression models. RESULTS: Ninety percent of the recent Salvadoran fathers who were surveyed participated in a prenatal care visit, attended the delivery, or participated in a postpartum well-baby care visit; 34% participated in all three of the activities. Attendance at delivery was most common, reported by 81% of fathers; the most common reason that subjects cited for not attending was that they had had to work. CONCLUSIONS: A large majority of the Salvadoran fathers participated in at least one prenatal care visit, delivery, or a postpartum well-baby care visit. While attendance alone does not necessarily indicate that men are supporting their partners, the results suggest that norms are in place for men to play positive roles in maternal-child health matters. Furthermore, the participation of fathers in these maternal and child health care activities may provide new opportunities to educate and further support men in both their own health and their family's health.

Use of a Western theoretical model to investigate the relationships among characteristics of pregnant women, utilization, and satisfaction with prenatal care services in St. Petersburg, Russia.

Few studies of utilization and satisfaction with prenatal care services have been conducted internationally. In this study, utilization and satisfaction with prenatal care services in St. Petersburg, Russia were examined using Aday and Andersen's (1974) A Framework for the Study of Access to Medical Care. This study was conducted under the auspices of the European Region, World Health Organization (WHO) Healthy Cities Project, which promotes a community-based intersectoral approach to meeting health needs. The convenience sample included 397 women with uncomplicated pregnancies and normal deliveries, representing an 86% response rate. Multiple regression and path analysis found significant predictors of prenatal care utilization and satisfaction. They were different, however, from those posited in the theoretical model. This indicates that Aday and Andersen's health care services model is specific to the U. S. health care system, where it originated. The Russian health care system has been and remains different from that of the United States. If the reformed Russian health care system takes on aspects of the U. S. health care system, the utility of Aday and Andersen's theoretical model may change.
