Introduction Recruiting participants for research studies can be challenging. Many studies fall short of their target or must prolong recruitment to reach it. We examined recruitment and retention strategies and report lessons learned in a behavioral intervention developmental trial to encourage healthy pregnancy weight gain and stress reduction in low-income overweight pregnant women. Methods In the San Francisco Bay area from February 2010 through March 2011, we used direct and indirect strategies to recruit English-speaking overweight and obese pregnant women who were aged 18 to 45, were in the early stages of pregnancy, and who had an annual household income less than 500% of the federal poverty guidelines. Eligible women who consented participated in focus groups or an 8-week behavioral intervention. We identified successful recruiting strategies and sites and calculated the percentage of women who were enrolled and retained. Results Of 127 women screened for focus group participation, 69 were eligible and enrolled. A total of 57 women participated in 9 focus groups and 3 women completed individual interviews for a completion rate of 87%. During recruitment for the intervention, we made contact with 204 women; 135 were screened, 33% were eligible, and 69.1% of eligible women enrolled. At 1 month postpartum, 82.6% of eligible women completed an assessment. Recruiting at hospital-based prenatal clinics was the highest-yielding strategy. Conclusion The narrow window of eligibility for enrolling early stage pregnant women in a group intervention presents obstacles. In-person recruitment was the most successful strategy; establishing close relationships with providers, clinic staff, social service providers, and study participants was essential to successful recruitment and retention.

Suzanne Barakat; Diana Martinez; Melanie Thomas; Margaret A. Handley

Many women develop postpartum mental health symptoms, ranging from the maternity blues to clinically diagnosed postpartum depression (PPD). Substantial literature supports an association between depression and type 2 diabetes, but there is limited literature regarding to what extent this relationship pertains to gestational diabetes (GDM) and postpartum depression. Review of the literature regarding GDM and PPD with a particular focus on describing the prevalence of PPD among women who may be at increased risk for GDM, including low-income and ethnic minority groups, was performed. Literature searches were conducted across four databases for studies reporting postpartum mental health outcomes (including postpartum depression, behavioral symptoms, mental disorders, mood, anxiety, quality of life) following a diagnosis of GDM. Studies including subgroups of women with GDM were included if postpartum mental health outcomes were reported. Of the 245 abstracts identified, ten studies were included in the final review. Findings suggest that PPD was high among low-income, ethnic minority women. Additional research is required to understand the complex relationship between GDM and PPD among low-income women, with the ultimate goal of implementing tailored interventions to address their medical and psychiatric needs.

ABSTRACT Objective/Background: Poor sleep quality is common in pregnancy and associated with increased psychological distress, which has adverse consequences for families. Emerging theory suggests that mindfulness-based interventions may help reduce cognitive and emotional reactivity to stressful events. The current study examines the effects of a mindfulness-based intervention on the relationship between poor sleep quality and increased depression symptom severity and perceived stress during pregnancy. Additionally, we explored the prevalence of poor sleep quality in this unique sample and the impact of intervention on sleep quality. Participants: Participants were 215 ethnically diverse, overweight and obese, predominantly low-income pregnant women drawn from a study examining the impact of an 8-week mindfulness-based program (Mindful Moms Training; MMT) to reduce excessive gestational weight gain, stress, and depression compared to treatment as usual (TAU). Methods: Participants reported global sleep quality, depressive symptoms, and perceived stress at baseline and postintervention. Results: Most participants (63%) were categorized as poor sleepers at baseline. MMT participants did not experience significantly greater improvement in sleep quality compared to TAU participants. Baseline poor global sleep quality predicted increased depression symptom severity for all participants. Baseline poor global sleep quality predicted increased perceived stress for the TAU group only; this association was not evident in the MMT group. Conclusions: Poor sleep quality is prevalent in overweight and obese predominantly low-income pregnant women. Poor sleep quality was associated with worsening psychological distress, but mindfulness training significantly attenuated the influence of poor sleep on perceived stress.

OBJECTIVE This study aimed to determine cervical cancer screening rates among women with severe mental illness. METHODS California Medicaid administrative records (2010-2011) for 31,308 women with severe mental illness were examined. Participants received specialty mental health services and were not dually eligible for Medicare. Poisson models assessed association between selected predictors and cervical cancer screening. RESULTS Overall, 20.2% of women with severe mental illness received cervical cancer screening during the one-year period. Compared with white women, Asian women (adjusted risk ratio [ARR]=1.23), black women (ARR=1.10), and Hispanic women (ARR=1.11) (p<.001) were more likely to have been screened. Women ages 28-37 were more likely than those ages 18-27 to have been screened (ARR=1.31, p<.001). Evidence of other health care use was the strongest predictor of screening (ARR=3.07, p<.001). CONCLUSIONS Most women in the sample were not regularly screened for cervical cancer. Cervical cancer screening for this high-risk population should be prioritized.

Objectives: Depressive symptoms are associated with preterm birth among adults. Pregnant adolescents have high rates of depressive symptoms and low rates of treatment; however, few interventions have targeted this vulnerable group. Objectives are to: (a) examine impact of CenteringPregnancy® Plus group prenatal care on perinatal depressive symptoms compared to individual prenatal care; and (b) determine effects of depressive symptoms on gestational age and preterm birth among pregnant adolescents. Method: This cluster-randomized controlled trial was conducted in 14 community health centers and hospitals in New York City. Clinical sites were randomized to receive standard individual prenatal care (n = 7) or CenteringPregnancy® Plus group prenatal care (n = 7). Pregnant adolescents (ages 14–21, N = 1,135) completed the Center for Epidemiologic Studies Depression Scale during pregnancy (second and third trimesters) and postpartum (6 and 12 months). Gestational age was obtained from medical records, based on ultrasound dating. Intention to treat analyses were used to examine objectives. Results: Adolescents at clinical sites randomized to CenteringPregnancy® Plus experienced greater reductions in perinatal depressive symptoms compared to those at clinical sites randomized to individual care (p = .003). Increased depressive symptoms from second to third pregnancy trimester were associated with shorter gestational age at delivery and preterm birth (<37 weeks gestation). Third trimester depressive symptoms were also associated with shorter gestational age and preterm birth. All p < .05. Conclusions: Pregnant adolescents should be screened for depressive symptoms prior to third trimester. Group prenatal care may be an effective nonpharmacological option for reducing depressive symptoms among perinatal adolescents.

We examined the prospective associations of objective and subjective measures of stress during pregnancy with infant stress reactivity and regulation, an early-life predictor of psychopathology. In a racially and ethnically diverse low-income sample of 151 mother-infant dyads, maternal reports of stressful life events (SLE) and perceived stress (PS) were collected serially over gestation and the early postpartum period. Infant reactivity and regulation at 6 months of age was assessed via maternal report of temperament (negativity, surgency, and regulation) and infant parasympathetic nervous system physiology (respiratory sinus arrhythmia [RSA]) during the Still Face Paradigm. Regression models predicting infant temperament showed higher maternal prenatal PS predicted lower surgency and self-regulation but not negativity. Regression models predicting infant physiology showed higher numbers of SLE during gestation predicted greater RSA reactivity and weaker recovery. Tests of interactions revealed SLE predicted RSA reactivity only at moderate to high levels of PS. Thus, findings suggest objective and subjective measures of maternal prenatal stress uniquely predict infant behavior and physiology, adjusting for key pre- and postnatal covariates, and advance the limited evidence for such prenatal programming within high-risk populations. Assessing multiple levels of maternal stress and offspring stress reactivity and regulation provides a richer picture of intergenerational transmission of adversity.

Background. Low-income minority women with prior gestational diabetes mellitus (pGDM) or high BMIs have increased risk for chronic illnesses postpartum. Although the Diabetes Prevention Program (DPP) provides an evidence-based model for reducing diabetes risk, few community-based interventions have adapted this program for pGDM women. Methods. STAR MAMA is an ongoing randomized control trial (RCT) evaluating a hybrid HIT/Health Coaching DPP-based 20-week postpartum program for diabetes prevention compared with education from written materials at baseline. Eligibility includes women 18–39 years old, ≥32 weeks pregnant, and GDM or BMI > 25. Clinic- and community-based recruitment in San Francisco and Sonoma Counties targets 180 women. Sociodemographic and health coaching data from a preliminary sample are presented. Results. Most of the 86 women included to date (88%) have GDM, 80% were identified as Hispanic/Latina, 78% have migrant status, and most are Spanish-speaking. Women receiving the intervention indicate high engagement, with 86% answering 1+ calls. Health coaching callbacks last an average of 9 minutes with range of topics discussed. Case studies presented convey a range of emotional, instrumental, and health literacy-related supports offered by health coaches. Discussion. The DPP-adapted HIT/health coaching model highlights the possibility and challenge of delivering DPP content to postpartum women in community settings. This trial is registered with ClinicalTrials.gov NCT02240420.

Purpose In these times of rapidly changing health care policies, those involved in the health care of women, especially during the reproductive years, have a unique and daunting opportunity. There is great potential to positively impact women’s health through focus on prevention, attention to addressing disparities, and new focus on the integration of behavioral health care in primary care settings. Description In this report from the field, we suggest that the integration of mental health care into other health services and addressing underlying social needs by partnering with community-based organizations should be a top priority for all settings seeking to provide excellent health care for women. Assessment We describe our experience in a diverse, urban, safety net system to draw attention to four areas of innovation that others might adapt in their own systems: (1) addressing social support and other social determinants of health; (2) tailoring services to the specific needs of a population; (3) developing integrated and intensive cross-disciplinary services for high-risk pregnant women; and (4) bridging the divide between prenatal and postpartum care. Conclusion Women are more likely to be engaged with healthcare during their pregnancy. This engagement, however limited, may be a unique “window of opportunity” to help them address mental health concerns and implement positive behavior change. Future work should include research and program evaluation of innovative programs designed to serve the entire family and meeting at-risk women where they are.

Objective To explore whether primary school entry is associated with changes in immune system parameters in HIV-affected children. HIV-affected children are vulnerable to psychosocial stressors, regardless of their own HIV serological status. Methods Data from 38 HIV-positive and 29 HIV-negative children born to seropositive women were obtained. Measures included family adversity questionnaires, autonomic nervous system (ANS) reactivity, and enumerative and functional changes in peripheral blood immune parameters. Results In comparison with children who were HIV-negative, children who were HIV-positive at baseline had fewer CD4+ T lymphocytes (mean [M] = 916 versus 1206 cells/mm3 × 103; F = 7.8, p = .007), more CD8+ cells (M = 1046 versus 720 cells/mm3 × 103; F = 7.98, p = .006), and diminished natural killer cell cytotoxicity (M = −0.29 versus 0.41; F = 8.87, p = .004). School entry was associated with changes in immune parameters, but HIV status was not associated with the magnitude of changes. Changes in immune parameters after school entry were associated with family stress and preschool entry ANS reactivity. Highly ANS reactive children had either the greatest increase in CD8+ cells after school entry or the greatest decrease, depending on reported levels of family adversity (B = 215.35; t = 3.74, p < .001). Changes in functional immune assays were significantly associated with the interactions between HIV status and ANS reactivity. Conclusions These results suggest that autonomic reactivity is associated with increased immunological sensitivity to adverse or challenging social contexts among children affected by HIV.

OBJECTIVE This study examined mammogram screening rates among women with severe mental illness by using a socioecological framework. Because it has been shown that people with severe mental illness receive less preventive health care overall, the analysis included psychosocial predictors of mammogram screening rates in a cohort of women with severe mental illness. METHODS This retrospective cohort study (N=14,651) used existing statewide data for women ages 48-67 in California with Medicaid insurance who received treatment in the specialty mental health care system. The primary outcome of interest was evidence of breast cancer screening via mammogram. The associations of each predictor of interest with mammogram screening were evaluated by using Poisson models with robust standard errors. RESULTS Across all demographic and diagnostic categories, rates of breast cancer screening in this cohort of women with severe mental illness fell below the national average. Only 26.3% (3,859/14,651) of women in the cohort received breast cancer screening in the past year. This study replicated previous findings that women with schizophrenia spectrum disorder and those with a comorbid substance use disorder are less likely to receive screening than those with other types of mental illness. In this cohort of women with severe mental illness, evidence of nonpsychiatric health care utilization was strongly associated with breast cancer screening (adjusted risk ratio=3.30, 95% confidence interval=2.61-4.16, p<.001). CONCLUSIONS The findings can inform efforts to improve breast cancer screening among women with severe mental illness, such as targeted outreach to population subsets and colocation of primary care services in mental health treatment settings.
