Maternal stress is associated with bacterial vaginosis in human pregnancy.

Objectives: Maternal infection, particularly bacterial vaginosis (BV) in pregnancy, is one of the leading causes of adverse perinatal outcomes. The determinants of individual differences in susceptibility, or vulnerability, to maternal infections are poorly understood. This study examines whether chronic maternal stress predisposes women to infection during pregnancy, and if so, whether the effects of chronic stress on infection are independent of other established risk factors. Methods: We conducted a cross-sectional, clinical prevalence study of chronic maternal stress and BV status in a sample of 454 pregnant women at 14.3 ± 0.3 weeks gestation (±SEM). BV was diagnosed by Gram-stain of vaginal fluid samples; chronic maternal stress was assessed using the Cohen Perceived Stress Scale. Other established risk factors for BV, including maternal age, race/ethnicity, marital status, SES, and behaviors related to feminine hygiene, sexual practices, and substance use, were measured using a structured interview. Results: Of the 454 women enrolled in this study, 224 (49%) were BV positive (Nugent score 7–10), 64 (14%) had intermediate vaginal flora (Nugent score 4–6), and 166 (37%) were BV negative (Nugent score 0–3). BV+ women had significantly higher chronic stress levels than BV− women (24.6 ± 0.5 vs. 22.2 ± 0.6 units (±SEM), respectively; t = 3.19; p < .01). Maternal sociodemographic variables (African-American race/ethnicity) and behavioral characteristics (vaginal douching, number of lifetime sexual partners, and use of illicit drugs) also were significantly associated with the presence of BV. After controlling for the effects of these variables, using a multivariable logistic regression model, chronic maternal stress remained a significant and independent predictor of BV status. Women in the moderate-stress group (third quartile) and high-stress (fourth quartile) group were 2.3 times (95% CI = 1.2–4.3) and 2.2 times (95% CI = 1.1–4.2) more likely to be BV+ than women in the low-stress group (bottom quartile). Conclusions: High levels of chronic stress during pregnancy are associated with bacterial vaginosis. The effect of chronic maternal stress is independent of the effects of other established sociodemographic and behavioral risk factors for BV.

Factors Associated with Intention to Breastfeed Among Low-Income, Inner-City Pregnant Women

Objectives: To examine the relationship between sociodemographic factors, maternal characteristics, and intention to breastfeed among low-income, inner-city pregnant women. Methods: English and Spanish speaking low-income women recruited from local Philadelphia health centers were surveyed at the time of their first prenatal care visit. At the time of the visit, respondents were asked whether or not they planned to breastfeed their infant. The responses of 2,690 women were included in these analyses. Multivariate logistic regression was used to assess the independent associations of race/ethnicity, nativity status, education, and other factors on the odds of intending to breastfeed. Results: About half (53%) of the respondents reported that they intended to breastfeed their infant. In adjusted logistic regression models, immigrant black (adjusted OR [aOR] 5.82; 95% confidence interval [CI] 3.86, 8.77), other Hispanic (who were predominantly foreign-born) (aOR 6.05; 95% CI 3.92, 9.33), and island-born Puerto Rican (aOR 3.48; 95% CI 2.04, 5.95) women were significantly more likely to report that they intended to breastfeed than non-Hispanic whites. Somewhat surprisingly, non-Hispanic, US-born African Americans in this low-income sample were more likely to report that they intended to breastfeed than non-Hispanic white respondents (aOR 1.59; 95% CI 1.20, 2.11). Lower education, not living with the babys father, multiparous pregnancy, and smoking were negatively and independently associated with intention to breastfeed. Maternal age, household income, public housing, and depressive symptoms were not significant predictors of breastfeeding intention in adjusted multivariate models. Conclusions: Significant differences were documented in breastfeeding intention in our sample of low-income, inner-city women. Most notable was the higher likelihood of anticipated breastfeeding among our immigrant sub-groups when compared with non-Hispanic white women. An unexpected finding was the higher likelihood of anticipated breastfeeding among native-born, non-Hispanic African American women than among non-Hispanic white respondents. Because intentions are important predictors of future behavior, more focus needs to be directed towards breastfeeding promotion during the prenatal period and towards a better understanding of why some mothers intend to breastfeed while others do not.

Literacy and depressive symptomatology among pregnant Latinas with limited English proficiency.

Latina immigrants with limited English proficiency face significant obstacles to using maternal health services. Using a measure of reading skill and problem solving in the health context (the Spanish version of the Test of Functional Health Literacy in Adults), the authors assessed the association between literacy in Spanish and depressive symptomatology among 99 Latinas receiving prenatal care who had limited English proficiency. After adjusting for potential confounds, women with inadequate literacy were found to be more than twice as likely to have Center for Epidemiological Studies-Depression Scale scores greater than 16 (the standard clinical threshold) than women with adequate literacy. The association between low literacy and depressive symptomatology among pregnant Latinas deserves further investigation and should be considered when designing health services for this vulnerable and growing population.

Smoking in pregnancy: patient and provider risk reduction behavior.

OBJECTIVE To describe the range of risk reduction behaviors among women who continue to smoke after learning of their pregnancy, including reduced tobacco use, eventual cessation, and sustained abstinence as well as the patient-reported smoking cessation-promoting behaviors of prenatal care providers. METHODS This research is part of a larger prospective, community-based study conducted to assess the association between maternal stress and birth outcomes and infant health and development. Over a 2-year period, from February 2000 to November 2001, women receiving prenatal care at a consortium of public health centers in Philadelphia, Pennsylvania, were consecutively recruited (n = 1,451) completing interviews at their initial prenatal visit and again 3 to 4 months following their delivery. Smoking rates during pregnancy were determined from responses given during the first postpartum interview, at 3 to 4 months postpartum. RESULTS Of the 1,451 women interviewed at 3 to 4 months postpartum, 24.9 percent indicated smoking during their pregnancy. Of these antenatal smokers, 89.0 percent reported reducing their cigarette consumption during pregnancy. However, only 25.4 percent attained abstinence during their pregnancy. Among women who achieved abstinence during their pregnancy, 21.7 percent were still not smoking at the time of the postpartum interview. Antenatal smokers reported that prenatal care providers asked about their smoking (90.6%) and advised about quitting (76.5%). However, only 27.9 percent were given referrals to smoking cessation programs. CONCLUSION While cessation was achieved by only a quarter of antenatal smokers, almost 90 percent reduced their cigarette consumption. Prenatal care providers identified and provided cessation advice to the majority of women who were smoking but they did not follow through with material assistance in the form of referrals to smoking cessation programs.

Variation in Nugent score and leukocyte count in fluid collected from different vaginal sites.

OBJECTIVE: To assess the variability in Nugent score and leukocyte count measured in vaginal secretions collected from 3 vaginal sites. METHODS: Fifty pregnant women at less than 20 weeks of gestation were consecutively recruited at the time of their first prenatal visit. Three vaginal smears were collected from each woman, 1 from the posterior fornix, 1 from the mid-lateral wall, and 1 from the introitus. Smears were Gram stained and evaluated for bacterial vaginosis using Nugents criteria. Each smear was classified as positive for bacterial vaginosis if the Nugent score was 7 or greater, intermediate if the score was between 4 and 6, and negative if the Nugent score was 3 or less. A mean leukocyte value was obtained for each slide by evaluating 5 fields under oil immersion. Repeated-measures analysis of variance was used to compare mean Nugent scores and leukocyte counts across sites. RESULTS: The sample consisted of mostly African-American, young, low-income women in their first trimester of pregnancy. Forty-seven percent were bacterial vaginosis–positive (Nugent score 7 or greater). Mean Nugent scores (± standard deviation) across the vaginal sample collection sites were similar: posterior fornix = 4.2 (4.4); mid-lateral wall = 4.2 (4.5); introitus = 4.2 (4.6). In contrast, the mean leukocyte count varied significantly across vaginal sample collection sites: 2.5 (4.2); mid-lateral wall = 2.8 (4.4); introitus = 6.5 (8.6) (F = 11.26 1, 47.5; P = .002). CONCLUSION: Leukocyte counts vary according to the site from which vaginal secretions were obtained, with the highest leukocyte count in samples obtained from the introitus. Bacterial vaginosis diagnosis by Nugent score does not vary by site of sample collection. LEVEL OF EVIDENCE: II-3

Continuous source of care among young underserved children: associated characteristics and use of recommended parenting practices.

OBJECTIVES The aim of this study was to 1) assess sociodemographic and health characteristics associated with having a continuous source of care (CSOC) among young children and 2) determine the relationship between having a CSOC and use of parenting practices. METHODS We conducted a prospective, community-based survey of women receiving prenatal care at Philadelphia community health centers. We conducted surveys at the first prenatal visit and at a mean age +/- standard deviation of 3 +/-1, 11 +/- 1, and 24 +/- 2 months postpartum, obtaining information on sociodemographic and health characteristics, childs health care provider, and 6 parenting practices. Group differences were tested between those with and without a CSOC by using the chi-square test for categorical variables and the Students t test for continuous variables. Logistic regression analysis was conducted to adjust for potential confounding variables. RESULTS Our sample consisted of 894 mostly young, African American, single women and their children. In the adjusted analysis, mothers of children with a CSOC, when compared with those without a CSOC, were more likely to have a high school education or less, be born in the United States, have a postpartum checkup, have stable child health insurance, and initiate care for their child at a site other than a community-based health center. Use of parenting practices was similar for children with and without a CSOC. CONCLUSIONS Maternal nativity, postpartum care, child health insurance, and initial site of infant care were associated with CSOC, but infant health characteristics were not. Use of parenting practices did not differ for those with and without a CSOC.

Unintended repeat pregnancy and low educational status: any role for depression and contraception use?

Objective—The purpose of this study was to assess the contribution of depressive symptoms and poor contraceptive use early in the first postpartum year to the risk of unintended repeat pregnancy at the end of that year among adults with low educational status (< 12th grade or equivalence). Study design—This was a prospective observational cohort study of 643 sexually active, lowincome, inner-city adult women (age ≥ 19) who enrolled prenatally (14.7 ± 6.9 weeks gestational age) and were followed twice after delivery (3.3 ± 1.3 months and 11.0 ± 1.3 months). Associations were assessed by multivariate logistic regression. Results—Low educational status (odds ratio, 2.32; 95% CI, 1.25-4.33) and less effective contraceptive use (odds ratio, 2.31; 95% CI, 1.05-4.51) were associated with unintended pregnancy. Neither depressive symptoms nor contraceptive use reduced the risk of pregnancy that was associated with low educational status. Conclusion—Low educational status was associated with more than twice the risk of unintended pregnancy 1 year after delivery. We found no evidence that depression or poor contraceptive use mediate this relationship.
