Maternal psychosocial factors associated with substance use in Mexican-origin and African American low-income pregnant women

PURPOSE: To describe ethnic-specific patterns of substance use before and during pregnancy in low-income pregnant women, examine the associations between psychosocial factors and patterns of substance use within ethnic groups, and assess maternal sociodemographic, prenatal, and psychosocial factors of women who continue to use substances during pregnancy and those who do not. METHOD: A prospective study of low-income, primiparous African American (n = 255), Mexican American (n = 525), and Mexican immigrant (n = 764) women was conducted in 22 prenatal care clinics in Los Angeles, CA. Data were collected in face-to-face interviews in both English and Spanish on prenatal life events, anxiety, sources of support, and substance use behaviors three months before and during pregnancy. FINDINGS: Significant ethnic differences were found in use of alcohol, cigarettes, and illicit drugs. African American women were more likely than Mexican-origin women to report use of substances before and during pregnancy. Mexican American women were more likely than Mexican immigrant women to report use of substances before and during pregnancy. Women who continued to use substances during pregnancy were less likely to be living with the baby's father, to have planned the pregnancy, to report having been able to go for prenatal care as soon as they wanted, and more likely to be identified at medical risk. CONCLUSIONS: Providers must increase the assessment and monitoring of substance use behaviors of low-income women in prenatal care settings. The role of health care providers must encompass advocacy and public health education.     

Evaluation of long-term follow-up of glomerular function in renal transplant recipients

The determinants and outcomes of unwanted pregnancies were explored in a prospective study of 1454 women who delivered in Moscow, Russia, during 1984-85. Mothers were interviewed during their postpartum hospital stay and again 3 years later. 131 women (9%) demonstrated a negative attitude toward their pregnancy. Another 72 women (5%) had a negative attitude initially, but developed positive feelings over the course of the pregnancy. The percentage of unwanted pregnancies was 2.9 times greater among unmarried women (14.9%) than married women (5.1%). Poor marital relationships, inadequate living conditions, tobacco/alcohol use, and low per capita income were found significantly more often among women with unwanted pregnancies. Significantly more infants of mothers with unwanted than wanted pregnancies had infants who were premature (28.3% vs. 9.5%) and low birth weight, but there was no significant difference in neonatal complications. Mothers of unwanted infants also were more likely to delay prenatal care and attend infrequently and, once the child was born, made fewer visits to the pediatrician. Even if unwanted pregnancy has no adverse medical sequelae, being unwanted should be considered a psychosocial risk factor with implications for a child's development.     

A prospective study of the effect of fundoplication on primary and secondary peristalsis in the esophagus

BACKGROUND: Delay of prenatal care is an important risk for poor birth outcome, yet its association with maternal knowledge and beliefs remains insufficiently studied. This research examined the relationship of unintended childbearing and beliefs about the importance of prenatal care with initiation after the first trimester, adjusting for key sociodemographic determinants. METHODS: One hundred fifty-four Texas hospitals accounting for 80 percent of state births were asked to collect surveys from all women delivering infants during a one-week interval in 1986. Seventy-four percent of hospitals and 70 percent of women participated (n = 2032). No differences occurred between the sample and the population on rates of delayed care and low birthweight or maternal demographics. RESULTS: Since delayed prenatal care is more frequent among low-income women, analyses were limited to those below the 200 percent poverty level. After adjustment for maternal age, marital status, education, parity, race, and health insurance status employing logistic regression, unintended births were 1.6 times more likely to involve delayed care. Mothers who believed prenatal care was unimportant were 2.1 times more likely to delay care. These coefficients exceeded or about equaled those for the covariates. CONCLUSIONS: Preconception education about the value of prenatal care and family planning programs to prevent unintended pregnancies should be conducted together with efforts to overcome financial and structural barriers if progress toward national prenatal care objectives is to be achieved.     

Talon cusp in permanent dentition associated with other dental anomalies: review of literature and reports of seven cases

A longitudinally linked data set for Georgia was used to identify characteristics, including previous prenatal care use and complications at the first birth, associated with prenatal care use in the second pregnancy among 8,224 African-American women. More than 70% of the women who were < 25 years of age at their first birth (younger women) and almost 40% of women who were > or = 25 years at their first birth received inadequate care with at least one of their first two births. Women who received inadequate care in their first pregnancy were more likely to receive inadequate care in their second pregnancy than women who received adequate care in their first pregnancy. Younger women with a history of a stillbirth, neonatal death, or vacuum extraction were less likely to receive inadequate care in their subsequent pregnancy. Although this study was not able to evaluate the content of prenatal care, it suggested that many African-American women may not receive sufficient care to prevent adverse pregnancy outcomes. Women who receive inadequate care in their first pregnancy must be targeted for interventions that help them overcome economic, situational, or attitudinal barriers to receiving adequate care in their next pregnancy.     

Comparison of two question sequences for assessing pregnancy intentions

Unintended pregnancies can have serious health, social, and economic consequences. Such pregnancies may be unwanted (a baby is not wanted at any time) or mistimed, yet wanted (a baby is wanted eventually). Intended pregnancies are those conceived when desired. Reproductive health survey respondents' understanding of these concepts and validity of survey results may be affected by question order and wording. Using a randomized crossover design, National Survey of Family Growth (NSFG) and Demographic and Health Survey (DHS) intendedness questions were asked in a 1993 survey of Arizona women aged 18-44 years. Of 2,352 ever-pregnant respondents, 25% gave discordant responses to DHS and NSFG questions about the most recent pregnancy. Age, marital status, household income, education, parity, time since pregnancy, and outcome of pregnancy were significantly predictive of discordant responses. DHS and NSFG questions yielded similar prevalence estimates of intendedness and wantedness; but young, unmarried respondents gave more "mistimed" responses on whichever question was asked later. Classifying pregnancies as intended, mistimed, or unwanted may be a problem for women who have not decided on lifetime reproductive preferences. Approaches to improving survey validity include addressing ambivalence, clarifying the definition of "unwanted," and, for young, unmarried women, not attempting to classify unintended pregnancies as mistimed or unwanted.     

New Mexico women with no prenatal care: reasons, outcomes, and nursing implications

A retrospective chart review was conducted to determine why women received no prenatal care during pregnancy and their subsequent maternal and neonatal outcomes. Five hundred and eighty medical records from 1990 through 1993 that were labeled as no care were reviewed. Actually, only 270 records had no care and of these, 92 had 156 recorded reasons as to why women did not receive prenatal care. These reasons were categorized into three types of barriers: attitudinal, sociodemographic, and system-related. The majority of the women were young, Hispanic, unmarried, between 20 and 29 years of age, and uninsured, and had one to three children. Overall, the women did not smoke cigarettes, drink alcohol, or use drugs during pregnancy. Overall, the women had good maternal and newborn outcomes. Results suggest a need to reevaluate the effect of prenatal care use on young Hispanic women.     

Maternal attitude toward pregnancy and the risk of neonatal death

OBJECTIVES: Reduced options for fertility control over the past decade have increased the rates of unwanted pregnancy. We evaluated whether a woman's negative attitude toward her pregnancy increased the risk of perinatal mortality, in a large, prospective cohort study. METHODS: The association between attitude toward the pregnancy and perinatal mortality was evaluated in a longitudinal cohort study of 8823 married, pregnant patients enrolled from 1959 to 1966 in the Child Health and Development Studies. RESULTS: Women who reported during the first trimester of prenatal care that the pregnancy was unwanted were more than two times more likely to deliver infants who died within the first 28 days of life than were women reporting accepted pregnancies. A positive attitude toward pregnancy was not associated with fetal death or post-neonatal death. CONCLUSIONS: These data, collected when induced abortions were illegal, may have important implications for the 1990s. If maternal attitude toward the pregnancy is associated with neonatal mortality and abortion laws change such that access is restricted, infant mortality may increase because a greater proportion of births will be unwanted.     

Protein solution structure calculations in solution: solvated molecular dynamics refinement of calbindin D9k

Data were collected on the drinking behavior of 415 pregnant adolescents from 1990 to 1994. The relationships between knowledge and attitudes about drinking and drinking behavior were examined. Knowledge about drinking was not related to average daily volume of alcohol before or during pregnancy. Those with specific knowledge about fetal alcohol effects drank less before pregnancy, and in the first trimester, and were also less likely to drink to intoxication. Among drinkers, general knowledge about drinking was significantly related to a decrease in drinking between pre-pregnancy and first trimester, as well as between first and third trimesters. Those with more intolerant attitudes about drinking drank less before and during pregnancy. They had fewer episodes of binge drinking, intoxication, negative consequences, and problem drinking during pregnancy. They were more likely to decrease drinking from the first to third trimesters. These relationships are relevant to developing effective education programs for the high-risk group of pregnant teenagers who drink.     

Factors affecting the use of folic acid supplements in pregnant women in Glasgow

BACKGROUND: Use of folic acid supplements preconception, and during the first trimester, is associated with a reduced incidence of first and subsequent neural tube defects. The Department of Health guidelines recommend the use of folic acid supplements by all women planning a pregnancy. AIM: To ascertain the proportion using folic acid supplements and the factors affecting their use. METHOD: Questionnaires were distributed postpartum to the 515 women who delivered normal babies in three maternity units in Glasgow over a four-week period. RESULTS: Forms were completed by 487 (95%) women. Only 57% took supplements at some point during their pregnancy, and only 21% took them before conception. Failure to take supplements was significantly associated with unplanned pregnancy, younger age, and previous pregnancies. Lack of awareness of the potential benefits associated with folic acid use was the commonest reason cited by women for not taking supplements. CONCLUSIONS: Increased health education through health care professionals and mass media campaigns can improve awareness and thereby increase the use of supplements in planned pregnancies. However, 42% of women in our study had unplanned pregnancies. Intake of folic acid supplements in this group can only be increased by improvements in dietary intake within the population as a whole, and by fortification of commonly ingested foods.     

Factors affecting number of prenatal care visits during second pregnancy among adolescents having rapid repeat births

PURPOSE: To examine factors associated with the number of prenatal care visits during second pregnancy for adolescents having a short interval between pregnancies. METHODS: The sample includes all adolescents aged 13 to 17 years whose first pregnancy resulted in a birth at a regional medical center in southeastern North Carolina from January 1983 to December 1989 and who had a repeat pregnancy within 24 months which resulted in a birth. We abstracted data from medical records and birth certificates. We fit a negative binomial regression model to determine the effects of various factors on the number of prenatal care visits during second pregnancy. RESULTS: The number of prenatal care visits during the first pregnancy, poor first birth outcome, interval between first and second pregnancy, and care provided by health department staff during first pregnancy were all positively associated with number of prenatal care visits during second pregnancy when controlling for gestation age of second birth. Other independent variables in the model included maternal age, education, black race, and being unmarried at the time of second birth. CONCLUSIONS: Because prenatal care is important for healthy mothers and babies, adolescents should be encouraged to seek prenatal care early in the first pregnancy. This could be an important time to implement interventions aimed at increasing prenatal care utilization in this and subsequent pregnancies.     

Reproductive health in diabetic women. A report of two cases demonstrating the importance of preconception care

BACKGROUND: Optimal glycemic control prior to and during early pregnancy is essential in diabetic women. CASES: Two cases of fetal anencephaly occurred in diabetic women who conceived with medical technical assistance but did not receive preconception counseling. Both women had poor glycemic control periconceptually, as evidenced by elevated glycosylated hemoglobin determinations in the early first trimester. Targeted sonographic evaluations in the second trimester revealed both fetuses to be anencephalic. Both women terminated their pregnancies. CONCLUSION: Women with diabetes should be encouraged to seek preconceptual counseling and achieve tight glycemic control prior to attempting pregnancy. Health care providers play a vital role in stressing the importance of preconception care to these patients.     

Family planning: an essential component of prenatal care

This nation's traditional approach to improving maternal and infant health has been prenatal care. But evidence is mounting that additional progress in reducing maternal and infant morbidity and mortality will depend, at least in part, on the care that a woman receives before she conceives. The studies reviewed in this paper indicate that increasing the interval between deliveries and preventing or delaying pregnancies among women at high risk could lower the rate of low birthweight (LBW). Since reducing the rate of unintended pregnancies would also reduce the number of pregnancies in women at high risk of LBW because of race, age, late or no prenatal care, and unhealthy behaviors, the prevention of unintended pregnancies would also reduce LBW. Unfortunately, prenatal care, as experienced by many women, devotes little attention to these family planning issues. Many women do not realize the importance of family planning to their own health and that of their children. Prenatal care providers should include instruction about the importance of pregnancy planning and encourage women to continue receiving health care between pregnancies. If the health of women and infants is to be improved, society must be willing to provide health services to women of reproductive age even when they are not pregnant.     

Preventive check-ups of pregnant women in Denmark. Common ailments in pregnancy

The study was conducted in order to describe the extent and content of advice on common ailments in pregnancy given by doctor or midwife during prenatal visits and to describe the frequency of ailments in the period before the visits. The design was a nationwide cross-sectional study based on questionnaires completed by pregnant women who had seen a general practitioner (GP), midwife or hospital doctor for prenatal care. Ailments and advice in connection with one specific visit were reported. The questionnaires were completed by 517 women after a prenatal visit to their GP (92% of eligible), by 514 women after a prenatal visit to the midwife (91% of eligible), and by 203 women after a prenatal visit to a doctor in the maternity department in pregnancy week 16-18 (84% of eligible). The results showed that nausea, pollakisuria, tiredness and heartburn had been present during the period before the visit in about half the women. Between a third and a fourth of the women had been discomforted by back pain, discharge or cramps. From 15 to 58 percent had been given advice, depending on the symptom. The advice was of many different kinds. To a large extent the women wanted to talk to the health professionals about the ailments, and most often they wanted to talk to a midwife about the ailments. We conclude that common ailments of pregnancy are frequent and they should be investigated more. Nearly all pregnant women want to talk about the subject during prenatal visits. The objectives of giving advice should be clearer, and clinical studies of the effectiveness of the advice are needed.     

Optimal CT scanning plan for long-bone 3-D reconstruction

OBJECTIVES: This study examined whether pregnancy intention was associated with cigarette smoking, alcohol drinking, use of vitamins, and consumption of caffeinated drinks prior to pregnancy and in early pregnancy. METHODS: Data from a telephone survey of 7174 pregnant women were analyzed. RESULTS: In comparison with women whose pregnancies were intended, women with unintended pregnancies were more likely to report cigarette smoking and less likely to report daily vitamin use. Women with unintended pregnancies were also less likely to decrease consumption of caffeinated beverages or increase daily vitamin use. CONCLUSIONS: Pregnancy intention was associated with health behaviors, prior to pregnancy and in early pregnancy, that may influence pregnancy course and birth outcomes.     

Maternal shunt dependency: implications for obstetric care, neurosurgical management, and pregnancy outcomes and a review of selected literature

OBJECTIVE: Because more women with cerebrospinal fluid shunts are surviving to child-bearing age, neurosurgeons, obstetricians, and other health care professionals require information about the care of these patients, especially during pregnancy and delivery. The purpose of this study was to gather comprehensive data from women with shunts regarding their clinical histories during and immediately after pregnancy. The following questions were addressed. 1) How does maternal shunt dependency influence the course of pregnancies and pregnancy outcomes? 2) What neurosurgical complications characterize this population of patients? 3) What complications of shunt dependency influence obstetric management, including prenatal testing and delivery? METHODS: A total of 37 respondents (age, 18-41 yr), accounting for 77 pregnancies, completed a questionnaire providing information on maternal background and medical history, shunt performance during pregnancy, management of delivery, pregnancy outcomes, and unusual complications. RESULTS: Fifty-six pregnancies resulted in live births; of these, 47 occurred in women with ventriculoperitoneal shunts. Three women underwent therapeutic abortions, 1 experienced preterm delivery, and 8 experienced 17 miscarriages. Four women experienced seizures during pregnancy, five reported third-trimester headaches, and eight described abdominal pains during the first and third trimesters. Four babies were diagnosed as having congenital defects. Shunt malfunctions and revisions occurred 10 times in 7 women, either during pregnancy or within 6 months after delivery. No acute malfunctions occurred during delivery. Forty-seven cases, representing 84% of all pregnancies, exhibited no shunt malfunctions or revisions. CONCLUSION: This study extends previous observations to a larger population of shunt-dependent mothers. The results suggest that maternal shunt dependency entails a relatively high incidence of complications but that proper care of these patients can lead to normal pregnancies and deliveries.     

Women with little or no prenatal care during pregnancy. Results of a study of twenty departments

OBJECTIVES: To estimate the frequency of women who have little or no health care during pregnancy, to assess associated perinatal risk, and to identify the corresponding risk factors. METHODS: Women who consulted less than 4 times or who began consultation during the third trimester were identified in public and private maternity units in 20 French departments. These women were compared with a sample of women from the same institutions who consulted regularly. RESULTS: The percentage of pregnant women with little or no care was 1.1%. Risk of premature birth was increased 4-fold compared with women who consulted regularly. Women who consulted little were very young, multiparous or living alone with no health care insurance. These women stated that the reason for not consulting was that their pregnancy was not accepted, financial difficulties and administrative problems. CONCLUSION: The lack of regular medical care results from social obstacles, especially in foreign born women but is also related to personal problems which are difficult to identify and manage.     

1988 National Maternal and Infant Health Survey: methods and response characteristics

OBJECTIVES: The 1988 National Maternal and Infant Health Survey (NMIHS) was conducted by the National Center for Health Statistics to study factors related to poor pregnancy outcome, such as adequacy of prenatal care; inadequate and excessive weight gain during pregnancy; maternal smoking, drinking, and drug use; and pregnancy and delivery complications. METHODS: The NMIHS is a nationally representative sample of 11,000 women who had live births, 4,000 who had late fetal deaths, and 6,000 who had infant deaths in 1988. Questionnaires were mailed to mothers based on information from certificates of live birth, reports of fetal death, and certificates of infant death. Information supplied by the mother, prenatal care providers, and hospitals of delivery was linked with the vital records to expand knowledge of maternal and infant health in the United States. RESULTS: The response rates in all three components of the NMIHS differed according to the mothers' characteristics. Mothers were more likely to respond if they were 20-39 years of age, were white, were married, had fewer than four children, entered prenatal care early, had more prenatal visits, had more years of education, or resided in the Midwest Region. The percent of respondents was lower for teenage mothers, mothers of races other than white, and mothers with four or more children, little prenatal care, or fewer years of education. Mothers whose infants weighed less than 2,500 grams were less likely to respond in the live-birth and infant-death components than mothers whose infants weighed 2,500 grams or more. CONCLUSIONS: The NMIHS will provide an invaluable tool for researchers and practitioners seeking solutions to perinatal and obstetric problems.     

Paediatric and ophthalmologic observations in offspring of alcohol abusing mothers

The offspring of nine women who had abused alcohol and drugs during pregnancy were studied. Of the 30 children, 10 had fetal alcohol syndrome (FAS) or fetal alcohol effects (FAE). Ophthalmological impairments associated with FAS--impaired vision, optic nerve hypoplasia, cataract, increased tortuosity of retinal vessels--were common. The severity of teratogenic lesions varied among the children and was often related to the level of abuse during pregnancy. Most women were unable to take care of their children during periods of substance abuse. All children with FAS/FAE had learning difficulties. Four mothers abstained from alcohol or drugs during some of their pregnancies and gave birth to children without birth defects.
