Group prenatal care and perinatal outcomes: a randomized controlled trial.

OBJECTIVE: To determine whether group prenatal care improves pregnancy outcomes, psychosocial function, and patient satisfaction and to examine potential cost differences. METHODS: A multisite randomized controlled trial was conducted at two university-affiliated hospital prenatal clinics. Pregnant women aged 14–25 years (n=1,047) were randomly assigned to either standard or group care. Women with medical conditions requiring individualized care were excluded from randomization. Group participants received care in a group setting with women having the same expected delivery month. Timing and content of visits followed obstetric guidelines from week 18 through delivery. Each 2-hour prenatal care session included physical assessment, education and skills building, and support through facilitated group discussion. Structured interviews were conducted at study entry, during the third trimester, and postpartum. RESULTS: Mean age of participants was 20.4 years; 80% were African American. Using intent-to-treat analyses, women assigned to group care were significantly less likely to have preterm births compared with those in standard care: 9.8% compared with 13.8%, with no differences in age, parity, education, or income between study conditions. This is equivalent to a risk reduction of 33% (odds ratio 0.67, 95% confidence interval 0.44–0.99, P=.045), or 40 per 1,000 births. Effects were strengthened for African-American women: 10.0% compared with 15.8% (odds ratio 0.59, 95% confidence interval 0.38–0.92, P=.02). Women in group sessions were less likely to have suboptimal prenatal care (P<.01), had significantly better prenatal knowledge (P<.001), felt more ready for labor and delivery (P<.001), and had greater satisfaction with care (P<.001). Breastfeeding initiation was higher in group care: 66.5% compared with 54.6%, P<.001. There were no differences in birth weight nor in costs associated with prenatal care or delivery. CONCLUSION: Group prenatal care resulted in equal or improved perinatal outcomes at no added cost.

Social Support and Social Conflict as Predictors of Prenatal Depression

OBJECTIVE: To estimate how social support and social conflict relate to prenatal depressive symptoms and to generate a brief clinical tool to identify women at increased psychosocial risk. METHODS: This is a prospective study following 1,047 pregnant women receiving care at two university-affiliated clinics from early pregnancy through 1 year postpartum. Structured interviews were conducted in the second trimester of pregnancy. Hierarchical and logistic regressions were used to examine potential direct and interactive effects of social support and conflict on prenatal depressive symptoms measured by the Center for Epidemiologic Studies-Depression Scale. RESULTS: Thirty-three percent of the sample reported elevated levels of depressive symptoms predicted from sociodemographic factors, social support, and social conflict. Social support and conflict had independent effects on depressive symptoms although social conflict was a stronger predictor. There was a “dose–response,” with each increase in interpersonal risk factor resulting in consequent risk for probable depression based on symptom reports (Center for Epidemiologic Studies-Scale greater than or equal to 16). A composite of one social support and three conflict items were identified to be used by clinicians to identify interpersonal risk factors for depression in pregnancy. Seventy-six percent of women with a composite score of three or more high-risk responses reported depressive symptoms. CONCLUSION: Increased assessment of social support and social conflict by clinicians during pregnancy can identify women who could benefit from group or individual interventions to enhance supportive and reduce negative social interactions.

Effects of group prenatal care on psychosocial risk in pregnancy: Results from a randomised controlled trial

Few interventions have succeeded in reducing psychosocial risk among pregnant women. The objective of this study was to determine whether an integrated group prenatal care intervention already shown to improve perinatal and sexual risk outcomes can also improve psychosocial outcomes compared to standard individual care. This randomised controlled trial included pregnant women ages 14–25 from two public hospitals (N = 1047) who were randomly assigned to standard individual care, group prenatal care or integrated group prenatal care intervention (CenteringPregnancy Plus, CP+). Timing and content of visits followed obstetrical guidelines, from 18-week gestation through birth. Each 2-h group prenatal care session included physical assessment, education/skills building and support via facilitated discussion. Using intention-to-treat models, there were no significant differences in psychosocial function; yet, women in the top tertile of psychosocial stress at study entry did benefit from integrated group care. High-stress women randomly assigned to CP+ reported significantly increased self-esteem, decreased stress and social conflict in the third trimester of pregnancy; social conflict and depression were significantly lower 1-year postpartum (all p-values < 0.02). CP+ improved psychosocial outcomes for high-stress women. This ‘bundled’ intervention has promise for improving psychosocial outcomes, especially for young pregnant women who are traditionally more vulnerable and underserved.

Pregnancy as a Window of Opportunity for HIV Prevention: Effects of an HIV Intervention Delivered Within Prenatal Care

OBJECTIVES We sought to determine whether an HIV prevention program bundled with group prenatal care reduced sexually transmitted infection (STI) incidence, repeat pregnancy, sexual risk behavior, and psychosocial risks. METHODS We conducted a randomized controlled trial at 2 prenatal clinics. We assigned pregnant women aged 14 to 25 years (N = 1047) to individual care, attention-matched group care, and group care with an integrated HIV component. We conducted structured interviews at baseline (second trimester), third trimester, and 6 and 12 months postpartum. RESULTS Mean age of participants was 20.4 years; 80% were African American. According to intent-to-treat analyses, women assigned to the HIV-prevention group intervention were significantly less likely to have repeat pregnancy at 6 months postpartum than individual-care and attention-matched controls; they demonstrated increased condom use and decreased unprotected sexual intercourse compared with individual-care and attention-matched controls. Subanalyses showed that being in the HIV-prevention group reduced STI incidence among the subgroup of adolescents. CONCLUSION HIV prevention integrated with prenatal care resulted in reduced biological, behavioral, and psychosocial risks for HIV.

Avoidance, Anxiety, and Sex: The Influence of Romantic Attachment on HIV-Risk among Pregnant Women

Most unprotected sex occurs in close relationships. However, few studies examine relational factors and sexual risk among high-risk populations. Romantic Attachment Theory states that individuals have cognitive working models for relationships that influence expectations, affect, and behavior. We investigated the influence of attachment avoidance and anxiety on sexual beliefs (e.g., condom use beliefs, self-efficacy), behavior (e.g., condom use, multiple partners, unprotected sex with risky partners), and sexually transmitted infections (STIs) among 755 high-risk, young pregnant women (ages 14–25) recruited from urban prenatal clinics. Attachment anxiety predicted sexual beliefs, condom use, and unprotected sex with risky partners controlling for demographic variables. Sexual beliefs did not mediate the relationship between attachment orientation and sexual behavior. Current relationship with the father of the baby did mediate the effect of attachment anxiety on multiple partners and STIs. Results indicate the importance of including general relational factors, such as attachment, in HIV prevention.

The effects of obesity and weight gain in young women on obstetric outcomes.

We investigated body mass index (BMI) and weight gain among pregnant women (ages 14 to 25) and assessed the relationship of BMI and weight gain on birth outcomes. We performed a secondary analysis of 841 women enrolled in a randomized controlled trial receiving prenatal care in two university-affiliated clinics. Almost half the patients were overweight or obese. An average of 32.3 +/- 23.6 pounds was gained in pregnancy with only 25.3% gaining the recommended weight and over half overgaining. Weight gain had a significant relationship to birth weight. Multivariate analysis showed that prepregnancy BMI but not weight gain was a significant predictor of cesarean delivery (odds ratio [OR] 1.91, confidence interval [CI] 1.24 to 2.69, P < 0.0001). When large-for-gestational-age infants were removed from the analysis, there was still a significant effect of BMI on cesarean delivery (OR 1.76, CI 1.17 to 2.66, P = 0.007) but not of weight gain (OR 1.45, CI 0.94 to 2.17, P = 0.093). Prepregnancy BMI is a more significant predictor of cesarean delivery than pregnancy weight gain in young women.

CAREGIVING HISTORY AND PRENATAL DEPRESSIVE SYMPTOMS IN LOW-INCOME ADOLESCENT AND YOUNG ADULT WOMEN: MODERATING AND MEDIATING EFFECTS

Prenatal depressive symptoms have been linked to negative outcomes for mothers and children. Using attachment theory as a framework, this study examined developmental differences in the interpersonal context of prenatal depressive symptoms among adolescents (age 14 to 19 years; n = 352) and young adults (age 20 to 24 years; n = 348). Participants included low-income, single, predominantly African American and Latina women. Moderating and mediating factors were found in the relation between caregiving history (perceived unavailability and inconsistency of maternal and paternal figures during childhood) and depressive symptoms. For pregnant adolescents, maternal unavailability predicted depressive symptoms whereas maternal inconsistency did not. In contrast, for pregnant young women, only maternal inconsistency predicted depressive symptoms; and this association was mediated by perceptions of prenatal support. For both groups, paternal caregiving history had a small yet independent association with depressive symptoms. Results highlight the need to consider developmental differences in the interpersonal context of prenatal depressive symptoms in delivering mental health interventions to young women of color.
