A randomized trial of a serialized self-help smoking cessation program for pregnant women in an HMO.

We report the results of a population-based randomized clinical trial that tested the effectiveness of a prenatal self-help smoking cessation program. The intervention consisted predominantly of printed materials received through the mail. The population (n = 242) consisted of a socioeconomically and ethnically diverse group of pregnant women enrolled in a large health maintenance organization (HMO) who reported they were smoking at the time of their first prenatal visit. Biochemical confirmation of continuous abstinence achieved prior to the 20th completed week of pregnancy and lasting through delivery revealed 22.2 per cent of the women in the eight-week serialized program quit versus 8.6 per cent of controls with usual care. The adjusted odds ratio was 2.80 (95 per cent CI = 1.17, 6.69). We conclude that a low-cost prenatal self-help intervention can significantly affect the public health problem of smoking during pregnancy and its associated risks for maternal and child health.     

Maternal Nutrition: An overview and adaptation to the hispanic client

White American, Hispanic, and African American women were surveyed in public health and low‐income clinics in Los Angeles, California, and Seattle, Washington, to determine if they delayed seeking prenatal care because of battering during their pregnancies. Nursing staff in the clinics attempted to enroll in the study all pregnant women from these groups who presented themselves for care; no other criteria were used, other than the ability to read either English or Spanish. Results were obtained from 162 White Americans, 208 Hispanics, and 132 African Americans. Although the incidence of abuse was not significantly different among the ethnic groups, battered women sought prenatal care 6.5 weeks later than the nonabused sample, with a similar delay in each ethnic group. Twenty‐one percent of the women reported physical harm during the pregnancy, and 13.7% stated that they had delayed care because of injuries.     

WIC participation and pregnancy outcomes: Massachusetts Statewide Evaluation Project.

The effects of WIC prenatal participation were examined using data from the Massachusetts Birth and Death Registry. The birth outcomes of 4,126 pregnant women who participated in the WIC program and gave birth in 1978 were compared to those of 4,126 women individually matched on maternal age, race, parity, education, and marital status who did not participate in WIC. WIC prenatal participants are at greater demographic risk for poor pregnancy outcomes compare to all women in the same community. WIC participation is associated with improved pregnancy outcomes, including, a decrease in low birthweight (LBW) incidence (6.9 per cent vs 8.7 per cent) and neonatal mortality (12 vs 35 deaths), an increase in gestational age (40.0 vs 39.7 weeks), and a reduction in inadequate prenatal care (3.8 per cent vs 7.0 per cent). Stratification by demographic subpopulations indicates that subpopulations at higher risk (teenage, unmarried, and Hispanic origin women) have more enhanced pregnancy outcomes associated with WIC participation. Stratification by duration of participation indicates that increased participation is associated with enhanced pregnancy outcomes. While these findings suggest that birth outcome differences are a function of WIC participation, other factors which might distinguish between the two groups could also serve as the basis for alternative explanations.     

Battering during pregnancy: tip of an iceberg revealed

Physical abuse of women is pervasive with one in three women experiencing battering. Battering occurs during pregnancy with women reporting blows to the pregnant abdomen, injuries to the breast and genitals, and sexual assault. A recent study in a large metropolitan area documented one in twelve pregnant women to have been physically battered during the present pregnancy. Among the women battered, 87% had been physically abused prior to pregnancy and 29% reported the abuse increased after becoming pregnant. Health care providers did not assess any of the women for abuse. When pregnancy outcome was analyzed in another study of 589 postpartum women, battered women were four times more likely to deliver a low-birthweight infant. This paper discusses the etiology of battering, prevalence of battering during pregnancy and pregnancy outcomes of battered women. A community-wide primary prevention program is presented that has linked the health care provider with law enforcement and shelters for battered women to interrupt the cycle of violence and promote the health and safety of pregnant women.

Smoking habits in early pregnancy and attitudes towards smoking cessation among pregnant women and their partners.

One-hundred and eighty-seven general practitioners in western Norway recorded smoking habits among 2379 women, consulting for their first regular medical check-up in pregnancy. Forty-six per cent had been daily smokers the last 3 months before pregnancy. Thirty-nine per cent were still smoking at the time of their first check-up. Sixteen per cent of the daily smokers stopped smoking spontaneously during the first few weeks of pregnancy. Fifty-seven per cent of women younger than 20 and 28% of women 30 years and older, did smoke at the first check-up. Single women smoked more often than women living with a partner (58% versus 38%). Smoking habits were not associated with number of previous pregnancies. At the first check-up, 530 pregnant women, still smoking daily, 18-34 years of age, living with a partner, accepted to participate in a smoking intervention study. They filled in a questionnaire about their smoking habits, the smoking habits of their partners and their attitudes towards smoking cessation. Sixty-five per cent reported a reduction in their use of cigarettes after becoming pregnant. The mean reduction in the number of cigarettes smoked daily was 4.0 (31%). Most of the respondents expressed a strong motivation to quit or reduce their smoking habits during their pregnancy. Seventy-two per cent of the partners were daily smokers. Reduction in the consumption of cigarettes, negative attitudes towards smoking and determination to stop smoking was significantly higher among women who were encouraged by their partners to stop smoking and in those who perceived that their partners were willing to reduce their consumption.     

Alcohol use prior to pregnancy recognition.

BACKGROUND: Frequent alcohol use during the first 8 weeks of pregnancy can result in spontaneous abortion and dysmorphologic changes in the developing organ systems of the embryo, including the heart, kidneys, and brain. However, few population-based studies are available that describe the prevalence of frequent drinking (6 or more drinks per week) among women prior to and during early pregnancy (the periconceptional period), and the sociodemographic and behavioral factors that characterize these women. Such knowledge is fundamental to the design of targeted interventions for the prevention of fetal alcohol syndrome (FAS) and other prenatal alcohol-related disorders. METHODS: This cross-sectional study used survey data collected by the National Center for Health Statistics as part of the 1988 National Maternal and Infant Health Survey (NMIHS). Weighted prevalence estimates were calculated using SUDAAN, and multivariate analyses were used to determine risk factors for frequent drinking. RESULTS: Forty-five percent of all women surveyed reported consuming alcohol during the 3 months before finding out they were pregnant, and 5% reported consuming 6 or more drinks per week. Sixty percent of women who reported alcohol consumption also reported that they did not learn they were pregnant until after the fourth week of gestation. Risk factors for frequent drinking during the periconceptional period included 1 or more of the following: being unmarried, being a smoker, being white non-Hispanic, being 25 years of age or older, or being college educated. CONCLUSIONS: Half of all pregnant women in this study drank alcohol during the 3 months preceding pregnancy recognition, with 1 in 20 drinking at moderate to heavy levels. The majority did not know they were pregnant until after the fourth week of pregnancy, and many did not know until after the 6th week. Alcohol is a teratogen capable of producing a number of adverse reproductive and infant outcomes. Public health measures needed to reduce these potentially harmful exposures include alcohol assessment, education, and counseling for women of childbearing age, with referral sources for problem drinking, and family planning services for pregnancy postponement until problem drinking is resolved.     

Lifetime and current abuse,pregnancy risks,and outcomes among Native American women

This study examines the effects of current abuse, battering during pregnancy, and lifetime physical and sexual abuse on pregnancy risks and outcomes among 30 urban Native American women. One-third of the women in this study were battered during the index pregnancy, and nearly two-thirds had been abused by their current partner. All but 3 women had experienced physical or sexual abuse in their lifetime, and nearly three-fourths had been multiply abused. Significant relationships were found between current partner abuse, decreased birth weight, and inadequate prenatal care. The variable, increased lifetime abuse events, was significantly associated with increased risk factors for preterm birth/low birth weight. High rates of substance use and sexually transmitted diseases were noted among women in this study. Further research is needed to examine abuse and relationships between abuse and pregnancy risks and outcomes among Native American women.     

Opportunities for intervention: discussing physical abuse during prenatal care visits

BACKGROUND: The American Academy of Pediatrics and the American College of Obstetricians and Gynecologists recommend that screening for physical abuse during prenatal care visits becomes routine. Although prenatal care visits offer a unique intervention opportunity, screening is not yet standard practice. DATA AND METHODS: We used data from the 1996 and 1997 Pregnancy Risk Assessment Monitoring System (PRAMS) to assess the prevalence of and the factors associated with health care providers' discussion of physical abuse with pregnant women in 14 states. PRAMS is a state-specific, population-based surveillance system that collects information from women on maternal behaviors before and during pregnancy, and at 2 to 6 months postpartum. RESULTS: Between 22% and 39% of the women surveyed reported that health care providers talked with them about physical abuse during prenatal care visits. Health care providers were more likely to discuss physical abuse with women who were black, Hispanic, young (aged <20 and 20 to 29), had a high school education or less, or paid for prenatal care with Medicaid. CONCLUSIONS: Our results indicate that most pregnant women do not report that their prenatal care providers discussed physical abuse with them. Logistic regression analyses identified consistent associations across the 14 states between discussion of abuse and demographic and pregnancy-related factors. A better understanding of the factors associated with whether a health care provider discusses physical abuse with a pregnant woman could increase intervention opportunities.     

Health-Related Quality of Life Among Pregnant Women With and Without Depression in Hubei, China

The role of prenatal depression on physical and mental health among women in mainland China has not been previously investigated. The aim of this research was to (a) calculate the prevalence of depression during pregnancy, (b) explore the relationship between depression sample characteristics and quality of life and (c) identify predictors of physical and mental health among pregnant women. This study was designed as a cross-sectional and exploratory survey. A total of 454 pregnant women participated in the study between December 2009 and June 2010 in central China. The data was collected using the Medical Outcomes Study short form 36 v2 and the Edinburgh Postnatal Depression Scale. Participants were recruited at outpatient departments of obstetrics and gynecology. Findings show that almost 40% of pregnant women experience prenatal depression. Depression was significantly associated with physical and mental health-related quality of life (HRQoL). Depression, increased age, higher gestational age, being employed and married were significant predictors of lower physical HRQoL. Depression, lower BMI and having an unintended pregnancy were significant predictors of lower mental HRQoL. Prenatal depression is very common in women from mainland China. Depressed women suffer from impaired physical and mental health; prenatal depression has a negative impact on women's HRQoL. We recommend that antenatal services integrate screening for depression into routine antenatal care.     

Promotion of folate for the prevention of neural tube defects: knowledge and use of periconceptional folic acid supplements in Western Australia, 1992 to 1995

Abstract: To assess changes in knowledge and use of folic acid supplements in relation to a statewide health promotion project for the prevention of neural tube defects, we surveyed general practitioners, pharmacists, women of child–bearing age and pregnant women in Western Australia. We also collected data on wholesale sales of folic acid supplements. By the end of the project, 56.5 per cent of general practitioner respondents knew that the recommended dose of folic acid was 0.5 mg and 70 per cent offered folic acid supplements to women planning pregnancy, 82.5 per cent of responding pharmacists knew the recommended dose, and 87.5 per cent reported an increase in sales of 0.5 mg folic acid. Wholesale sales of 0.5 mg folic acid increased markedly in Western Australia compared with other states. From shopping centre surveys of women of child–bearing age we estimated that their knowledge of the association between folate and spina bifida increased from 8.2 per cent before the project to 67.5 per cent 2.5 years later, and doctors were a major source of information for women. In a 1995 survey of a sample of pregnant women, 43.1 per cent with planned pregnancies had taken folic acid supplements periconceptionally, compared with 19.1 per cent in a similar survey in 1993.

Prenatal care and pregnancy outcomes during the recession: the Washington State experience.

To determine whether changes in prenatal care utilization and adverse pregnancy outcomes occurred among poor residents of Washington State during the recent recession, we examined all births occurring from 1980 to 1983 to women in the poorest census tracts of the three major metropolitan counties in Washington State (N = 15,735). A comparison sample consisted of all births occurring in the highest income census tracts (N = 16,295). Because the impact of the recession was hypothesized to be greatest in 1982, rates in 1982 were compared with rates in 1980. The proportion of births receiving late or no prenatal care increased in both the low-income tracts (6.2 per cent to 8.2 per cent) and the high-income tracts (1.6 per cent to 2.3 per cent). The proportion of low birthweight infants increased only in the low-income tracts (6.3 per cent to 7.4 per cent). The prevalence of maternal anemia (hematocrit less than 30) also increased only in the low-income tracts (0.7 per cent to 1.7 per cent). While we were unable to ascertain the financial status of the individuals who suffered the adverse outcomes, the findings for the low-income census tracts are consistent with the hypothesis that an increase in adverse pregnancy outcomes occurred among the poor in Washington State during the recent recession.     

Home pregnancy testing kits: prevalence of use, false-negative rates, and compliance with instructions.

This study investigated the prevalence of home pregnancy kit use, incidence of false-negative results, and compliance with testing procedures. Among 144 pregnant women, identified through three health care settings, prevalence of test-kit use was 28.5 per cent. The false-negative rate was 24.3 per cent. Total compliance with instructions was reported by only 32 per cent of users. Women testing less than nine days after menstrual period was due had false-negative rates of 33 per cent contrasted with 21 per cent for those testing after the nine days.     

Socioeconomic status and maternal cigarette smoking before, during and after a pregnancy

Abstract: Research suggests that cigarette use declines when women find out they are pregnant, increasing again after the birth. Pregnancy may provide many women with a substantial impetus to stopping smoking. Also, rates of smoking cessation and reduction may be class-related, with the highest socioeconomic-status groups manifesting higher rates of reduction. Using data from the Mater Hospital-University of Queensland Study of Pregnancy, we report family income related to rates of smoking before, during and after a pregnancy. Before becoming pregnant, 45.9 per cent of women in the sample were smokers. This declined to 34.7 per cent of women at their first clinic visit. Rates of heavy smoking (20 or more cigarettes per day) had returned to earlier levels by the six-month (after birth) follow-up. Women in the lowest family-income group had the highest rates of cigarette use before, during and after their pregnancy. Of the lowest family-income group, 8.4 per cent were heavy smokers before, during and after their pregnancy, compared with 2.8 per cent of women in the highest family-income group. Smoking cessation rates were highest in the highest family-income group (those who smoked least), but relapse rates after the birth were similar for all income groups. Arresting rates of smoking relapse by pregnant women should be seen as a major public health priority     

Recreational physical activity and the risk of preeclampsia: a prospective cohort of Norwegian women

Previous case-control studies suggest that recreational physical activity protects against preeclampsia. Using a prospective design, the authors estimated the risk of preeclampsia for pregnant women according to level of physical activity, taking other variables that influence risk into consideration. The data set comprised 59,573 pregnancies from the Norwegian Mother and Child Cohort Study (1999-2006). Information on physical activity and other exposures was extracted from questionnaire responses given in pregnancy weeks 14-22, whereas diagnosis of preeclampsia was retrieved from the Medical Birth Registry of Norway. Estimation and confounder control was performed with multiple logistic regression. About 24% of pregnant women reported no physical activity, and 7% reported more than 25 such activities per month. The adjusted odds ratio was 0.79 (95% confidence interval: 0.65, 0.96) for preeclampsia when comparing women who exercised 25 times or more per month with inactive women. The association appeared strongest among women whose body mass index was less than 25 kg/m(2) and was absent among women whose body mass index was higher than 30 kg/m(2). These results suggest that the preventive effect of recreational physical activity during pregnancy may be more limited than has been shown in case-control studies and may apply to nonobese women only.     

Chronic drug use and reproductive health care among low-income women in Miami,Florida: A comparative study of access,need, and utilization

Interviews of low-income women in Miami, FL, addressed reproductive health issues in a stratified, network-referred sample of chronic drug users (CDUs) and socially and ethnically similar women who were not CDUs. Women who were not CDUs were significantly more likely to report a regular source of health care than CDUs. About one third of each group reported experiencing reproductive health problems (other than pregnancy) in the 12 months preceding their interview. Chronic drug users were twice as likely to report that these problems remained untreated. Measures of use of preventive services (physical exam, breast exam, pelvic exam, family planning visit) consistently showed lower use by CDUs. A higher proportion of women who were not CDUs reported pregnancies in the 12 months preceding interview. The 32 pregnant CDUs were much less likely to have received prenatal care than the 42 pregnant women who were not CDUs. For women who reported a pregnancy in the year preceding interview, logistic regression analysis showed a strong and robust negative effect of being a CDU on receiving prenatal care even when the effects of having a usual source of care and having third-party coverage were controlled.     

Adverse Childhood Experiences and Pregnancy Intentions among Pregnant Women Seeking Prenatal Care

BackgroundThis study examined whether adverse childhood experiences (ACEs) are associated with increased risk of having an unwanted or mistimed pregnancy.MethodsWomen in two medical centers within an integrated health system were screened for ACEs during standard prenatal care (N = 745). Multinomial multivariable logistic regression analyses examined the associations of ACEs (count and type) with pregnancy intentions, adjusting for covariates.ResultsOverall, 58.3% of pregnant women reported no ACEs, 19.1% reported one ACE, and 22.7% reported two or more ACEs; 76.2% reported wanting to get pregnant, 18.5% reported wanting to get pregnant but not at this time (i.e., mistimed pregnancy), and 5.2% reported not wanting to get pregnant at all (i.e., unwanted pregnancy). Having two or more (vs. 0) ACEs was associated with higher odds of an unwanted pregnancy (odds ratio, 2.60; 95% confidence interval, 1.19–5.68). Further, childhood loss of parent (odds ratio, 2.20; 95% confidence interval, 1.03–4.71) and neglect (odds ratio, 5.67; 95% confidence interval, 1.72–18.72) were each associated with higher odds of an unwanted pregnancy in separate analyses. ACEs count and type were not significantly associated with having a mistimed pregnancy.ConclusionsAmong women screened for ACEs during standard prenatal care, ACEs were associated with increased odds of having an unwanted pregnancy, but not a mistimed pregnancy. Additional research is needed to better understand the mechanisms through which ACEs and other individual, social, and contextual factors impact pregnancy intentions to better support women and provide appropriate resources to help prevent unintended pregnancies.     

The effectiveness of smoking cessation methods for smokers in public health maternity clinics: a randomized trial.

Little insight is available in the literature on how best to assist the pregnant smoker in public health maternity clinics to quit during pregnancy. A randomized pretest/posttest experiment was used to evaluate the effectiveness of two different self-help cessation methods. Three hundred and nine pregnant women from three public health maternity clinics were assigned randomly to one of three groups with one-third assigned to each: a control group; a group receiving the American Lung Association's Freedom From Smoking Manual; and those receiving A Pregnant Woman's Self-Help Guide to Quit Smoking. Using a saliva thiocyanate (SCN) and behavioral report at mid-pregnancy and end of pregnancy to confirm cessation or reduction, 2 per cent in the control group quit and 7 per cent reduced their SCN levels substantially. Of the women assigned to the ALA method, 6 per cent quit and 14 per cent reduced their SCN levels substantially. Of the women who used the Guide, 14 per cent quit and 17 per cent reduced their SCN levels substantially. Results of this trial indicate that health education methods tailored to the pregnant smoker are more effective in changing smoking behavior than the standard clinic information and advice to quit and/or the use of smoking cessation methods not tailored to the needs of the pregnant smoker.     

Mental Health During Pregnancy: A Study Comparing Asian, Caucasian and Native Hawaiian Women

Objective: This study examines perinatal mental health issues, ethnic differences, and comorbidity among pregnant women in Hawaii. Methods: Eighty-four participants were recruited from women, ages 18–35, seeking prenatal care on Oahu. They were interviewed at their initial prenatal visit about substance use, depression, and anxiety. Results: Sixty-one percent of women screened positive for at least one mental health issue. Thirteen percent of all pregnant women reported drinking during pregnancy with 5% reporting problem drinking, 15% reported smoking cigarettes on a regular basis, 5% of pregnant women had probable depression, and 13% of pregnant women had probable anxiety. Significant ethnic differences were found in cigarette smoking, with the highest rate among Native Hawaiian women (35%). Native Hawaiian women were also more likely to binge drink. Conclusion: Given the high rates of potential mental health issues in our sample, our findings highlight the importance of screening and treatment for mental health issues early in pregnancy in Hawaii.
