Effects of prenatal factors and temperament on infant cortisol regulation in low-income Mexican American families

Prenatal psychosocial exposures can significantly affect infant health and development. Infants with higher temperamental negativity are theorized to be more susceptible to environmental exposures. We evaluated the interaction of prenatal maternal exposures and infant temperamental negativity to predict infant cortisol response to mildly challenging mother-infant interaction tasks. Participants included 322 Mexican American mother-infant dyads (mother age 18-42; 82% Spanish-speaking; modal family income $10,000-$15,000). Mothers reported depressive symptoms and social support prenatally and infant temperamental negativity at 6 weeks postpartum. Salivary cortisol was collected from infants before and after mother-infant interaction tasks at 12 weeks. Higher prenatal maternal depressive symptoms and lower social support predicted higher cortisol among infants with higher temperamental negativity. Higher infant temperamental negativity predicted an increase in maternal distress and a decrease in social support from prenatal to 12 weeks postpartum. Interactive influences of maternal social-contextual factors and infant temperament may influence the development of infant neurobiological regulation and promote or strain maternal and infant adaptation over time.

Yoga for prenatal depression: a systematic review and meta-analysis

BACKGROUND

Prenatal depression can negatively affect the physical and mental health of both mother and fetus. The aim of this study was to determine the effectiveness of yoga as an intervention in the management of prenatal depression.

METHODS

A systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted by searching PubMed, Embase, the Cochrane Library and PsycINFO from all retrieved articles describing such trials up to July 2014.

RESULTS

Six RCTs were identified in the systematic search. The sample consisted of 375 pregnant women, most of whom were between 20 and 40 years of age. The diagnoses of depression were determined by their scores on Structured Clinical Interview for DSM-IV and the Center for Epidemiological Studies Depression Scale. When compared with comparison groups (e.g., standard prenatal care, standard antenatal exercises, social support, etc.), the level of depression statistically significantly reduced in yoga groups (standardized mean difference [SMD], -0.59; 95% confidence interval [CI], -0.94 to -0.25; p = 0.0007). One subgroup analysis revealed that both the levels of depressive symptoms in prenatally depressed women (SMD, -0.46; CI, -0.90 to -0.03; p = 0.04) and non-depressed women (SMD, -0.87; CI, -1.22 to -0.52; p < 0.00001) were statistically significantly lower in yoga group than that in control group. There were two kinds of yoga: the physical-exercise-based yoga and integrated yoga, which, besides physical exercises, included pranayama, meditation or deep relaxation. Therefore, the other subgroup analysis was conducted to estimate effects of the two kinds of yoga on prenatal depression. The results showed that the level of depression was significantly decreased in the integrated yoga group (SMD, -0.79; CI, -1.07 to -0.51; p < 0.00001) but not significantly reduced in physical-exercise-based yoga group (SMD, -0.41; CI, -1.01 to -0.18; p = 0.17).

CONCLUSIONS

Prenatal yoga intervention in pregnant women may be effective in partly reducing depressive symptoms.

The relationship between maternal depressive, anxious, and stress symptoms during pregnancy and adult offspring behavioral and emotional problems

BACKGROUND

Prenatal maternal depressive, anxious, and stress symptoms have been found to be associated with child and adolescent behavior problems. In this paper, we investigate their impact on behavior problems and depressive symptoms in adulthood.

METHODS

Participants included 3,099 mother-offspring pairs from the Mater University Study of Pregnancy (MUSP), an Australian based, prebirth cohort study. We used latent class growth analysis (LCGA) with parallel processes to identify trajectories of maternal depressive, anxious, and stress symptoms over four time periods between the mothers' first clinic visit and 5 years postpregnancy. We fitted the estimates from the maternal trajectories in multivariate logistic regression models to predict internalizing and externalizing behavior at age 21. We adjusted for a wide range of prenatal and postnatal factors, including maternal life events, relationship quality, contact with the new born, as well as concurrent maternal depressive and anxious symptoms and father's history of mental health problem.

RESULTS

LCGA found seven groups of mothers; one group of mothers exhibited high levels of depressive, anxious, and stress symptoms during pregnancy but not at later time points. Their offspring experienced increased levels of behavior problems and depressive symptoms.

CONCLUSIONS

This paper provides the first evidence that high levels of maternal subjective depressive, anxious, and stress symptoms experienced in early pregnancy may predict internalizing and externalizing behavior problems and depressive symptoms in young adults.

Relationship of prenatal depression and comorbidities to infant outcomes

OBJECTIVE

The purpose of this study was to provide information on the effect of prenatal depression and anxiety as assessed in the context of obstetrical care on key infant outcomes (gestational age at birth, birth weight, and APGAR scores), while simultaneously considering interactions with maternal medical conditions among primarily Medicaid enrollees.

METHODS

Obstetrical medical records of 419 women presenting consecutively for prenatal care at a health system serving primarily Medicaid patients were examined. Information on maternal characteristics (age, race, education) and maternal medical health (BMI, high blood pressure, diabetes, and kidney problems), as well as mental health information, was extracted. Depression was assessed as part of routine care using the Patient Health Questionnaire-9 (PHQ-9), and any documentation of depression or anxiety by the obstetrics clinician was also used in the analyses.

RESULTS

Approximately one-third of the sample showed some evidence of prenatal depression, either based on PHQ-9 score (≥10) or clinician documentation of depression, and close to 10% showed evidence of anxiety. Multivariate analyses showed significant interactions between depression and anxiety on gestational age and birth weight, between depression and high blood pressure on gestational age, and also between anxiety and kidney problems on gestational age.

CONCLUSION

Among this sample, the effect of maternal depression and anxiety on birth outcomes was more evident when considered along with maternal chronic medical conditions. This information may be used to assist prenatal care clinicians to develop risk assessment based on knowledge of multiple risk factors that may exert and additive influence on poor birth outcomes.

Reliability and validity of the center for epidemiologic studies-depression scale in screening for depression among HIV-infected and -uninfected pregnant women attending antenatal services in northern Uganda: a cross-sectional study

BACKGROUND

There are limited data on the prevalence and approaches to screening for depression among pregnant women living in resource poor settings with high HIV burden.

METHODS

We studied the reliability and accuracy of the Center for Epidemiologic Studies Depression (CES-D) scale in 123 (36 HIV-infected and 87 -uninfected) pregnant women receiving antenatal care at Gulu Regional Referral Hospital, Uganda. CES-D scores were compared to results from the psychiatrist-administered Mini-International Neuropsychiatric Interview (MINI) for current major depressive disorder (MDD), a "gold standard" for assessing depression. We employed measures of internal consistency (Cronbach's alpha), and criterion validity [Area Under the Receiver Operating Characteristic Curve (AUROC), sensitivity (Se), specificity (Sp), and positive predictive value (PPV)] to evaluate the reliability and validity of the CES-D scale.

RESULTS

35.8% of respondents were currently experiencing an MDD, as defined from outputs of the MINI-depression module. The CES-D had high internal consistency (Cronbach's alpha = 0.92) and good discriminatory ability in detecting MINI-defined current MDDs (AUROC = 0.82). The optimum CES-D cutoff score for the identification of probable MDD was between 16 and 17. A CES-D cutoff score of 17, corresponding to Se, Sp, and PPV values of 72.7%, 78.5%, and 76.5%, is proposed for adoption in this population and performs well for HIV-infected and -uninfected women. After adjusting for baseline differences between the HIV subgroups (maternal age and marital status), HIV-infected pregnant women scored 6.2 points higher on the CES-D than HIV-uninfected women (p = 0.032).

CONCLUSIONS

The CES-D is a suitable instrument for screening for probable major depression among pregnant women of mixed HIV status attending antenatal services in northern Uganda.

Prenatal depressive symptoms and abnormalities of glucose tolerance during pregnancy among Hispanic women

The aim of this study is to prospectively examine the association between maternal depressive symptoms in early pregnancy and risk of abnormal glucose tolerance (AGT) and impaired glucose tolerance (IGT) in mid-pregnancy. We evaluated this association among 934 participants in Proyecto Buena Salud, a prospective cohort study of Hispanic (predominantly Puerto Rican) women in Western Massachusetts. Depressive symptoms were assessed in early pregnancy using the 10-item Edinburgh Postnatal Depression Scale. Scores ≥13 indicated at least probable minor depression and scores ≥15 indicated probable major depression. AGT and IGT were diagnosed using American Diabetes Association criteria. In early pregnancy, 247 (26.5 %) participants experienced at least minor depression and 163 (17.4 %) experienced major depression. A total of 123 (13.2 %) were classified with AGT and 56 (6.0 %) were classified with IGT. In fully-adjusted models, the odds ratio for AGT associated with minor depression was 1.20 (95 % CI 0.77-1.89) and for major depression was 1.34 (95 % CI 0.81-2.23). The odds ratio for IGT associated with minor depression was 1.22 (95 % CI 0.62-2.40) and for major depression was 1.53 (95 % CI 0.73-3.22). We did not observe an association with continuous screening glucose measures. Findings in this prospective cohort of Hispanic women did not indicate a statistically significant association between minor or major depression in early pregnancy and AGT or screening glucose values in mid-pregnancy. Due to the small number of cases of IGT, our ability to evaluate the association between depression and IGT risk was constrained.

Maternal depressive, anxious, and stress symptoms during pregnancy predict internalizing problems in adolescence

BACKGROUND

Studies have shown a link between maternal-prenatal mental health and offspring behavior problems. In this paper, we derived longitudinal trajectories of maternal depressive, anxious, and stress symptoms over early life to predict offspring behavior in adolescence.

METHODS

Participants included 3,925 mother-offspring pairs from the Mater University Study of Pregnancy (MUSP), an Australian-based, prebirth cohort study. Latent class growth analysis with parallel processes was used to identify trajectories of maternal depressive, anxious, and stress symptoms over four measurement periods between the mothers' first clinic visit and 5 years postpregnancy. The estimates from the maternal trajectories were used to fit multivariate logistic regression models and predict internalizing and externalizing behavior at age 14. We adjusted for a wide range of factors, including a number of prenatal confounders, concurrent maternal depressive and anxious symptoms, father's history of mental problems, and maternal life events relationship quality and contact with the new born.

RESULTS

Seven maternal trajectories were identified one of which isolated high levels of depressive, anxious, and stress symptoms during pregnancy. After adjustment for confounders, this was the only trajectory that predicted higher internalizing behavior in adolescence. No specific maternal trajectory predicted externalizing problems.

CONCLUSIONS

We found evidence for a prenatal effect, whereby high levels of maternal depression, anxiety, and stress symptoms in early pregnancy uniquely increased the risk of internalizing behavior problems in adolescence.

Antenatal Depression is Not Associated with Low-Birth Weight: A Study from Urban Pakistan

BACKGROUND

Low-birth weight (LBW) (<2500 g) is considered to be a leading cause of cognitive impairment and physical disabilities in children. Incidence of LBW in South Asia has been reported to be as high as 33%. We investigated the association between antenatal depression and LBW in an urban community, in Karachi, Pakistan.

METHODS

A total of 1357 pregnant women in their third trimester were recruited into the study. They were screened for antenatal depression with Edinburgh postnatal depression scale. Self-reporting questionnaire was also used to measure psychological distress. Birth weights of 763 newborns were obtained from the hospital records.

RESULTS

We did not find a significant association between antenatal depression and LBW (odds ratio 0.881, 95%CI 0.732-1.060) in mothers attending a charity run hospital in an urban setting in Pakistan.

CONCLUSION

Antenatal depression is not associated with LBW in this urban population in Pakistan. However, the prevalence of depression is high during pregnancy. There is a need to develop culturally adapted psychosocial interventions to address the high rates of depression for this population group.

Recent intimate partner violence as a prenatal predictor of maternal depression in the first year postpartum among Latinas

The study aims to determine if recent intimate partner violence (IPV) is a prenatal risk factor for postpartum depression (PPD) among pregnant Latinas seeking prenatal care. A prospective observational study followed Latinas from pregnancy through 13 months postpartum. Prenatal predictors of PPD included depression, recent IPV exposure, remote IPV exposure, non-IPV trauma history, poverty, low social support, acculturation, high parity, and low education. Postpartum depression was measured at 3, 7, and 13 months after birth with the Beck's Depression Inventory-Fast Screen. Strength of association was evaluated using bivariate and multivariable odds ratio analysis. Subjects were predominantly low income, monolingual Spanish, and foreign-born, with mean age of 27.7. Recent IPV, prenatal depression, non-IPV trauma, and low social support were associated with greater likelihood of PPD in bivariate analyses. Recent IPV and prenatal depression continued to show significant association with PPD in multivariate analyses, with greater odds of PPD associated with recent IPV than with prenatal depression (adjusted OR = 5.38, p < 0.0001 for recent IPV and adjusted OR = 3.48, p< 0.0001 for prenatal depression). Recent IPV exposure is a strong, independent prenatal predictor of PPD among Latinas. Screening and referral for both IPV and PPD during pregnancy may help reduce postpartum mental health morbidity among Latinas.

Prenatal depression in women hospitalized for obstetric risk

OBJECTIVE

Little is known about depression during pregnancy in women with high maternal or fetal risk, as this population is often excluded from research samples. The aim of this study was to evaluate depressive symptoms and known risk factors for depression in a group of women hospitalized with severe obstetric risk.

METHOD

In the antenatal unit, 129 inpatients completed the Edinburgh Postnatal Depression Scale (EPDS), the Dyadic Adjustment Scale (DAS), and the Maternal Antenatal Attachment Scale (MAAS) from October 2005 through December 2006. A subset of women were administered the Mood Disorders module of the Structured Clinical Interview for DSM-IV Axis I Disorders based on a score of > or = 11 on the EPDS. Obstetric complications were classified according to the Hobel Risk Assessment for Prematurity.

RESULTS

Fifty-seven of the 129 women (44.2%) scored 11 or greater on the EPDS, and at least 25/129 (19.4%) met the DSM-IV criteria for major depressive disorder. Mothers reporting high attachment to the fetus on the MAAS reported lower severity of depressive symptoms (rho = -0.33, p < .0001); those reporting interpersonal relationship dissatisfaction on the DAS endorsed higher depressive severity (rho = -0.21, p = .02). Severity of obstetric risk was unrelated to depression, but one complication, incompetent cervix, was positively associated with level of depressive symptomatology.

CONCLUSION

Findings indicate a higher prevalence rate of major depressive disorder in women with severe obstetric risk than that reported in low-risk pregnancy samples, suggesting the need for routine depression screening to identify those who need treatment. Fewer depressive symptoms were reported by mothers reporting strong maternal fetal attachment and greater relationship satisfaction.
