A Life Course Perspective on Depressive Symptoms in Mid-Pregnancy

Objective: To examine the prevalence of depressive symptoms in mid-pregnancy and their relation to life circumstances across the life course in a community-based sample. Methods: The Pregnancy Outcomes and Community Health (POUCH) Study enrolled women at 16–26 weeks' gestation from 52 clinics in five Michigan communities. At enrollment women completed a screening instrument for depressive symptoms (CES-D) and questions about life circumstances covering three “periods,” i.e. previous 6 months, adulthood, and childhood. Questions were grouped into sub-constructs (e.g., abuse, economic, substance use, loss, and legal) for each “period” and evaluated in relation to CES-D scores. Analyses included 1321 POUCH participants divided into three subgroups: teens; women ≥20 years insured by Medicaid (disadvantaged); and women ≥20 years not insured by Medicaid (advantaged). Results: A positive CES-D screen (≥16) was more common in teens (46%) and disadvantaged women (47%) than in advantaged women (23%). Recent problems (previous 6 months) with abuse, economics, and substance use in someone close were each associated with higher adjusted mean CES-D scores (2.3–7.5 increase) in the three subgroups of women. In life course analyses, abuse and substance use in teens, and abuse and economic problems in disadvantaged and advantaged women were strongly linked to higher adjusted mean CES-D scores when these problems occurred both in childhood and adulthood (range 2.2–7.1 increase), whereas the associations were more modest when problems were confined to childhood. Conclusions: Strategies for addressing the public health problem of depressive symptoms in mid-pregnancy will benefit from a life course perspective.     

Longitudinal Study of Depressive Symptoms and Health-Related Quality of Life During Pregnancy and After Delivery: The Health Status in Pregnancy (HIP) Study

Objective Depressive symptoms are known to affect functioning in early pregnancy. We estimated the effect of a change in depressive symptoms status on health-related quality of life (HRQoL) throughout pregnancy and after delivery. Methods Longitudinal study of 200 women. The independent variable was depressive symptoms, defined as a Center for Epidemiologic Studies Depression (CES-D) score of ≥16. The dependent variable was HRQoL from 8 domains of the Medical Outcomes Study (SF-36) Short Form. Women were categorized based on the change in CES-D score: (1) never depressed, (2) became well, (3) became depressed and (4) always depressed. A random effects model was used to (1) estimate the effect of a change in depressive symptomatology from the first to the second trimester on HRQOL in the second trimester and (2) estimate the change in depressive symptomatology from the second to the third trimester on HRQoL in the third trimester and after delivery, adjusting for covariates. Intra-individual correlations were accounted for using generalized estimating equations (GEE). Results The proportion of women with depressive symptoms was 15%, 14%, and 30% in the first, second and third trimesters, respectively, and 9% after delivery. Women who became depressed had scores in the social domains that were 10–23 points and 19–31 points lower in the second and third trimesters, respectively, compared to women with no depressive symptoms. Women who became well had scores that were 3–31 points lower, compared to women with no depressive symptoms. Conclusions Alterations in depressive symptomatology have a substantial effect on functioning during pregnancy and after delivery. This paper was presented, in part, at the 134th Annual Meeting of the American Public Health Association, Boston, MA on November 8, 2006.     

Prevalence,Stability, and Socio-Demographic Correlates of Depressive Symptoms in Black Mothers During the First 18 Months Postpartum

Objectives: The goals of this longitudinal study were to evaluate 1) the prevalence and stability of high depressive symptom levels during the first 18 months postpartum in a sample of otherwise healthy Black mothers varying in socio-economic status and 2) the relation of socio-demographic variables and level of socio-demographic risk to maternal depressive symptom levels during this time period. Methods: Participants were 163 Black adult mothers of healthy, full-term infants. The level of mothers' depressive symptomatology was assessed at 2, 3, 6, 12, and 18 months postpartum using the Center for Epidemiological Studies-Depression Scale (CES-D). Mothers provided socio-demographic information at each assessment. Univariate and bivariate analyses were used to analyze the data. Results: The percentage of mothers with an elevated CES-D score (16 or higher) at single visits ranged from 13.5 to 14.7%, and 35.0% had at least one elevated CES-D score by 18 months postpartum. CES-D total scores were significantly correlated across each pair of visits (mean r = 0.57, all p's < 0.0001), and average CES-D scores did not change significantly over time. Single marital status, low-income status, and more negative maternal perceptions of the adequacy of income for meeting familial needs were significantly related to higher maternal CES-D scores at each assessment (all p's < 0.05). Level of socio-demographic risk, as assessed with a composite risk score derived from these variables, was significantly related to higher average CES-D scores (averaged across visits) (p < 0.0001) and to a greater frequency of elevated CES-D scores (16 or higher) during the first 18 months postpartum (p = 0.0002). Conclusions: The prevalence and stability of high levels of maternal depressive symptomatology during the first 18 months postpartum in this sample of Black women are consistent with those reported in prior studies of community samples of mothers unselected for race. Mothers with higher socio-demographic risk profiles had higher levels of maternal depressive symptoms at each assessment point.     

Prenatal Depression in Latinas in the U.S. and Mexico

Objectives The study aimed to investigate the prevalence of depressive symptoms and their associated risk factors during pregnancy in Latinas in the United States (U.S.) and Mexico. Method The sample included 108 women in the U.S. whose data were obtained from medical chart reviews in a community clinic in Washington, D.C., and 117 women in Mexico who participated in face-to-face interviews in the waiting rooms of primary care community centers in Mexico City. Variables, chosen to match in both countries for comparisons, were: socio-demographics, pregnancy gestation and order, social support, depressive symptoms, personal history of depression, family psychiatric history, and suicidal thoughts. Depressive symptoms were measured using the Center for Epidemiological Studies Depression Scale (CES-D). Results The prevalence of depressive symptoms was 32.4% for pregnant Latinas and 36.8% for Mexicans (CES-D ≥ 16), and 15.7% and 23.9% (CES-D ≥ 24), respectively, with no differences between groups. Separate multiple logistic regression analyses showed that for U.S. Latinas: (1) being more educated predicted depressive symptoms (CES-D ≥ 16), and (2) second trimester, as compared to first, also predicted symptoms (CES-D ≥ 24). (3) History of suicidal thoughts predicted symptoms in Latinas in the U.S. (CES-D ≥ 24) and in Mexico (using both definitions of high symptoms), and (4) living with a partner but not formally married and multi-parous condition predicted symptoms (CES-D ≥ 24) among pregnant Mexicans. Conclusions A high prevalence of depressive symptoms and significant risk factors during pregnancy were found in Latinas in U.S. and Mexico, suggesting increased risk for postpartum major depression. Implications for screening and interventions are discussed.

Longitudinal Study of Depressive Symptoms and Social Support in Adolescent Mothers

Previous studies have suggested that adolescent mothers with higher social support have lower depressive symptoms. This is a longitudinal study of adolescent mothers to examine the association of social support and depressive symptoms over one year postpartum. This was a prospective study of adolescent mothers (N at baseline = 120, N at 1 year = 89; age < 19 years) enrolled in a teen tot program. Participants completed the Center for Epidemiological Studies Depression Scale for children (CES-DC) and the Duke-UNC Functional Social Support Questionnaire at baseline, 12 weeks, and 1 year. A score of ≥ 16 on the CES-DC was suggestive of major depression. The mean CES-DC scores of the adolescent mothers were ≥16 points at all three time points (baseline: mean = 18.7 ± 10.3; 53% ≥ 16; 12 weeks: mean = 18.4 ± 11.4, 57% ≥ 16; one year: mean = 20.0 ± 11.4; 57% ≥ 16). Social support had a significant, inverse association with depressive symptoms for all participants from baseline to 12 weeks with a stronger association for those with more depressive symptoms (score ≥ 16) at baseline (beta = −0.030 ± 0.007; P < 0.001) than for those with fewer depressive symptoms (score < 16) at baseline (beta = −0.013 ± 0.006; P = 0.021). From 12 weeks to one year, increased social support was only significantly associated with decreased depressive symptoms for those with a higher baseline level of depressive symptoms (beta = − 0.039 ± 0.009; P < 0.001). Depressive symptoms were prevalent among adolescent mothers. For more depressed adolescent mothers, higher levels of social support were associated with less depressive symptoms over the 1 year follow-up. Effective long-term interventions are needed to lessen depression and enhance social support.     

Impact of a Health Promotion Intervention on Maternal Depressive Symptoms at 15?months Postpartum

Given that diet, physical activity, and social support are associated with depression, we examined whether a health promotion intervention designed to modify these factors in low-income, postpartum women would reduce depressive symptoms. This study used a randomized, controlled design to examine the effect of the Just for You (JFY) Program, an educational intervention promoting healthy lifestyles through home visits by nutrition paraprofessionals and motivational telephone counseling, on postpartum depressive symptoms. A total of 679 women income-eligible for the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) were recruited at 6-20 weeks post delivery and randomized to Usual WIC Care or JFY. Using an intention-to-treat analysis, the authors modeled depressive symptoms on the Center for Epidemiologic Studies Depression Scale (CES-D) among 403 women (59%) completing follow-up at a mean of 15 months infant age, adjusting for baseline CES-D, age, household income and randomization strata (body mass index (BMI), race/region). As a secondary analysis, the authors evaluated potential mediators related to social support and self-efficacy to change one or more health behaviors targeted by the intervention. Women randomized to JFY reported 2.5 units lower CES-D score (P = 0.046) compared with those receiving Usual WIC Care alone. This relationship was attenuated by change in self-efficacy (β = −2.3; P = 0.065), suggesting this construct may partially have mediated the effect of JFY on maternal depressive symptoms. A health promotion intervention delivered through home visits and telephone calls can reduce depressive symptoms at 15 months postpartum among low-income, ethnically diverse women.     

Maternal Body Mass Index and Self-Reported Postpartum Depressive Symptoms

Objectives: The association between extremes of body mass index (BMI) and depression in women has been documented, yet little is known about the relationship between obesity and postpartum depression (PPD). This study seeks to characterize the association between BMI and PPD. Methods: The 2000–2001 Utah data from Pregnancy Risk Assessment Monitoring System (PRAMS) were used to determine the proportion of women, stratified by prepregnancy body mass index, reporting postpartum depressed mood and stressors during pregnancy. Results: The prevalence of self-reported moderate or greater depressive symptoms was 27.7% (S.E. ±2.2) in underweight, 22.8% (±1.2) in normal weight, 24.8% (±2.9) in overweight and 30.8% (±2.5) in obese women. After controlling for marital status and income, normal BMI (19.8–25.9) was associated with the lowest rate of self-reported postpartum depressive symptoms. There was a two-fold increase in self-reported depressive symptoms requiring assistance among overweight and obese women compared to normal weight women (1.53% normal, 2.99% overweight, and 3.10% obese [p < 0.001]). Obese women were significantly more likely to report emotional and traumatic stressors during pregnancy than normal weight women. Conclusion: This population-based survey suggests a potential association between prepregnancy body mass index and self-reported postpartum depressive symptoms. Prospective studies of association between obesity and PPD, with improved diagnostic precision are warranted.     

The Role of Social Networks and Support in Postpartum Women's Depression: A Multiethnic Urban Sample

Objectives: This study examined the relationship of social support, and of social networks, to symptoms of depression in a multiethnic sample of women having recently given birth. Methods: Women at community health centers in a Northeastern city were randomly sampled from groups stratified by race/ethnicity (African American, Hispanic, and White) and postpartum interval. Mother's score on the Center for Epidemiologic Studies of Depression Scale (CES-D) was the dependent variable. Main independent variables included the Medical Outcomes Study (MOS) Social Support Survey and a social network item. Univariate statistics assessed the relationship between CES-D score and each of the independent variables. Multivariate linear regression models included core sociodemographic variables alone, the core model with each of the social support and social network variables added separately, and all variables together. We evaluated interactions between race and social support, race and social networks, and social support and social networks. Results: The multivariate models with MOS Social Support and core variables indicated that each 10-point increase in the MOS Social Support Survey was related to a 2.1-unit lower score on the CES-D (95% CI −2.4, −1.7). The inclusion of the social network variable into the core model showed that having two or more friends or family members available was associated with a 13.6-point lower mean score on the CES-D (95% CI −17.5, −9.6), compared to women reporting none or only one available person. Conclusions: Both social support and social networks were statistically significant and independently related to depressive symptomatology.     

Acculturation and Depressive Symptoms Among Pregnant and Postpartum Latinas

Objectives Among childbearing Latinas, higher acculturation has been found to be significantly associated with increased risk for mental health problems (Acevado (Child Abuse Neglect, 24:11–127, 2000)), although these findings have been inconsistent (Beck (Maternal Child Nurs, 31(2), 114–120, 2006)). The aims of this study are to assess and compare the prevalence of elevated depressive symptoms among pregnant and postpartum U.S.- and Mexican-born Latinas, and to describe the relation of elevated depressive symptoms and acculturation indicators. Methods A convenience sample of 439 pregnant and postpartum Latinas attending Public Health Clinics in San Antonio, Texas was screened for depressive symptoms using the Center for Epidemiologic Studies Depression (CES-D) Scale. Women with a score of 21 or greater were classified as having elevated depressive symptoms. Sociodemographic data, including birth country and language of interview, were collected as indicators of acculturation. Results 21% of the sample had moderate depressive symptoms; 15% met the threshold for high depressive symptoms. Bivariate analysis showed Latinas who were U.S.-born, single, preferred English or were pregnant were more likely to express elevated levels of depressive symptoms. Being U.S.-born, pregnant and single was significantly associated with moderate levels of depressive symptoms in logistic regression analyses controlling for other variables in the model. Controlling for other variables, being pregnant and single was significantly associated with high levels of depressive symptoms. Conclusions Higher acculturation, pregnancy and single status were positively associated with elevated depressive symptoms. Screening for depression during pregnancy is important for this population group, given Latinas’ high rates of fertility and births to single women, particularly among more acculturated, U.S.-born Latinas.     

Postpartum Depression Prevalence and Impact on Infant Health,Weight, and Sleep in Low-Income and Ethnic Minority Women and Infants

This study aimed to investigate the prevalence of maternal depressive symptoms at 5 and 9 months postpartum in a low-income and predominantly Hispanic sample, and evaluate the impact on infant weight gain, physical health, and sleep at 9 months. Participants included 132 low-income mother-infant pairs who participated in a larger investigation on prenatal care utilization. Mothers were interviewed in person 24–48 h after birth and by phone at 5 and 9 months postpartum. Clinically significant levels of depressive symptoms were reported in 33% of the women at 5 months postpartum, and 38% at 9 months postpartum. Higher depressive symptoms at 5 months were associated with less infant weight gain from 5 to 9 months, p = .002, increased infant physical health concerns, p = .05, and increased infant nighttime awakenings at 9 months, p = .001. Results suggest a striking prevalence of clinically significant depressive symptoms through 9 months postpartum in this very low income, largely ethnic minority sample. Further, the effects of postpartum depression include significant ramifications for infant physical health.     

Birth Outcomes,Postpartum Health and Primary Care Contacts of Immigrant Mothers in an Australian Nulliparous Pregnancy Cohort Study

To investigate differences and similarities in birth outcomes, postpartum health and primary care contacts of mothers born overseas of non-English speaking background (NESB) compared with Australian-born mothers. Nulliparous women were recruited in early pregnancy (≤24 weeks gestation) to a prospective pregnancy cohort study from six metropolitan public hospitals in Victoria, Australia. Analyses are based on questionnaires completed in pregnancy and at 3 months postpartum. Of the 1,507 women recruited in the study, 1,431 women (95%) were followed up at 3 months postpartum. Immigrant mothers of NESB (n = 212) and Australian born mothers (n = 1,074) had similar obstetric outcomes and postpartum physical health outcomes. Immigrant women were more likely to say they had been depressed for 2 weeks or longer since the birth (Adj OR = 1.92, 95% CI 1.3–2.8); to report relationship problems (Adj OR = 1.39, 95% CI 0.9–2.1) and to report lower emotional satisfaction with their relationship with the partner (Adj OR = 1.69, 95% CI 1.1–2.6) after adjusting for age, education status, income, method of birth and genital tract trauma. Immigrant mothers were less likely to be asked about feeling low or depressed by general practitioners (OR = 0.79, 95% CI 0.5–0.9) and about relationship problems by maternal and child health nurses (OR = 0.68, 95% CI 0.5–0.9). Immigrant women of NESB reported greater psychological distress, less emotional satisfaction with their partner and more relationship problems in the first 3 months postpartum than Australian born women. Although immigrant mothers had an equivalent level of contact with primary care practitioners in the first 3 months postpartum, they were less likely to be asked about their emotional well-being or about relationship problems by health professionals.     

Risk Factors for Sub-Clinical and Major Postpartum Depression Among a Community Cohort of Canadian Women

Objectives To identify prenatal and perinatal factors that predict women at risk of sub-clinical and major postpartum depression among a cohort of low medical risk pregnant women in Canada. Methods Data from 1,403 women who completed a randomized controlled trial of supplementary support during pregnancy was analyzed to identify risk factors for sub-clinical and major postpartum depression. The Edinburgh Postnatal Depression Scale (EPDS), completed at eight weeks postpartum, was used to classify each woman’s depression symptom severity. Demographic, obstetric, behavioral risk, mental health and psychosocial factors were considered. Multiple logistic regression analyses were used to identify risk factors most predictive of sub-clinical and major postpartum depression. Results After adjustment for other covariates, variables that increased the risk of sub-clinical postpartum depression included a history of depression (OR = 2.27, CI = 1.42–3.63), anxiety symptoms during pregnancy (OR = 2.12, CI = 1.09–4.11), being born outside Canada (OR = 1.87, CI = 1.17–3.00), and low parenting self-efficacy (OR = 1.65, CI = 1.06–2.55). Variables that increased the risk of major postpartum depression included a history of depression (OR = 2.78, CI = 1.56–4.97), being born outside Canada (OR = 2.97, CI = 1.70–5.17), depressive symptoms during pregnancy (OR = 2.83, CI = 1.29–6.19) and not breastfeeding at eight weeks postpartum (OR = 2.12, CI = 1.21–3.70). Conclusions A history of depression and being born outside Canada predicted women who were at an increased risk of sub-clinical and major postpartum depression. The remaining risk factors specific to sub-clinical and major postpartum depression suggest some differences between women vulnerable to sub-clinical compared to major depressive symptoms in the postpartum period, which may have implications for targeted screening and intervention strategies.     

#40-S association of depression with increases of plasma fibrinogen concentrations in midlife women

PURPOSE: Plasma fibrinogen has emerged as a risk factor for cardiovascular disease in adults. We want to compare the fibrinogen levels in depressed women (CES-D > 16) vs. non-depressed women (CED-D ⩽ 16) using the baseline data from the Study of Women's Health Across the Nation (SWAN).METHODS: The plasmatic levels of fibrinogen were measured in 3198 women, aged 42–52 years from SWAN study. Depression status was determined during the same visit using scores ⩾16 from the Center for Epidemiological Studies-Depression Scale (CES-D).RESULTS: The prevalence of depression (CES-D ⩾ 16) was 24.3% (778/3198). Plasma fibrinogen levels were significantly increased (304.1 ± 72.2 vs. 290.6, ± 66.8 mg/dl; p <. 05) in depressed women. These differences were not explained by measured other variables, including smoking, ethnicity, prevalent diseases, and the use of non-psychotropic medications.CONCLUSION: Our results suggest that raised fibrinogen levels in midlife women would be associated with the presence of depression.     

Psychometric properties of the Center for Epidemiologic Studies Depression Scale (CES-D) in French clinical and nonclinical adults

BackgroundPrevious research on the Center for Epidemiologic Studies Depression Scale (CES-D) has five main limitations. First, no study provided evidence of the factorial equivalence of this instrument across samples of depressive and community participants. Second, only one study included systematic tests of measurement invariance based on confirmatory factor analyses (CFA), and this study did not consider the higher-order factor structure of depression, although it is the CES-D global scale score that is most often used in the context of epidemiological studies. Third, few studies investigated the screening properties of the CES-D in non-English-language samples and their results were inconsistent. Fourth, although the French version of the CES-D has been used in several previous studies, it has never been systematically validated among community and/or depressed adults. Finally, very few studies have taken into account the ordered-categorical nature of the CES-D answer scale. The purpose of the study reported herein was therefore to examine the construct validity (i.e., factorial, reliability, measurement invariance, latent mean invariance, convergence, and screening properties) of the CES-D in a French sample of depressed patients and community adults.MethodsA total sample of 469 participants, comprising 163 clinically depressed patients and 306 community adults, was involved in this study. The factorial validity, and the measurement and latent mean invariance of the CES-D across gender and clinical status, were verified through CFAs based on ordered-categorical items. Correlation and receiver operator characteristic curves were also used to test the convergent validity and screening properties of the CES-D.ResultsThe present results: (i) provided support for the factor validity and reliability of a second-order measurement model of depression based on responses to the CES-D items; (ii) revealed the full measurement invariance of the first- and second-order measurement models across gender; (iii) showed the partial strict measurement invariance (four uniquenesses had to be freely estimated, but the factor variance–covariance matrix also proved fully invariant) of the first-order factor model and the complete measurement invariance of the second-order model across patients and community adults; (iv) revealed a lack of latent mean invariance across gender and across clinical and community subsamples (with women and patients reporting higher scores on all subscales and on the full scale); (v) confirmed the convergent validity of the CES-D with measures of depression, self-esteem, anxiety, and hopelessness; and (vi) demonstrated the efficacy of the screening properties of this instrument among clinical and nonclinical adults.ConclusionThis instrument may be useful for assessing depressive symptoms or for the screening of depressive disorders in the context of epidemiological studies targeting French patients and community men and women with a background similar to those from the present study.     

Unintended Pregnancy and Perinatal Depression Trajectories in Low-Income,High-Risk Hispanic Immigrants

Perinatal depression is a prevalent and detrimental condition. Determining modifiable factors associated with it would identify opportunities for prevention. This paper: 1) identifies depressive symptom trajectories and heterogeneity in those trajectories during pregnancy through the first-year postpartum, and 2) examines the association between unintended pregnancy and depressive symptoms. Depressive symptoms (BDI-II) were collected from low-income Hispanic immigrants (n=215) five times from early pregnancy to 12-months postpartum. The sample was at high-risk for perinatal depression and recruited from two prenatal care settings. Growth mixture modeling (GMM) was used to identify distinct trajectories of depressive symptoms over the perinatal period. Multinomial logistic regression was then conducted to examine the association between unintended pregnancy (reported at baseline) and the depression trajectory patterns. Three distinct trajectory patterns of depressive symptoms were identified: high during pregnancy, but low postpartum (“Pregnancy High”: 9.8%); borderline during pregnancy, with a postpartum increase (“Postpartum High”: 10.2%); and low throughout pregnancy and postpartum (“Perinatal Low”: 80.0%). Unintended pregnancy was not associated with the “Pregnancy High” pattern, but was associated with a marginally significant nearly four fold increase in risk of the “Postpartum High” pattern in depressive symptoms (RRR=3.95, p<0.10). Family planning is a potential strategy for the prevention of postpartum depression. Women who report unintended pregnancies during prenatal care must be educated of their increased risk, even if they do not exhibit antenatal depressive symptoms. Routine depression screening should occur postpartum, and referral to culturally appropriate treatment should follow positive screening results.     

Intimate Partner Violence/Abuse and Depressive Symptoms among Female Health Care Workers: Longitudinal Findings

Intimate partner violence and abuse (IPV/A) have been shown to have a major impact on mental health functioning. This study assessed the longitudinal association between recent IPV/A and depressive symptoms to identify potential targets for preventive interventions for women. Random effects models were used to examine four waves of data collected at 6-month intervals from a cohort of 1,438 female health care workers. IPV/A (e.g., sexual and physical violence, psychological abuse) in the past 5 years was associated with higher Center for Epidemiologic Studies Depression Scale (CES-D) 10 scores across four waves after adjustment for age, time, marital status, and childhood trauma. Women who reported IPV/A in the past 5 years had higher CES-D 10 scores (β, 1.31; 95% confidence interval, 0.79–1.82; p < .0001) than nonabused women. This association was generally constant with time, suggestive of a cross-sectional association across all four waves of data. Additionally, recent IPV/A was associated with change in depressive symptoms over time among the full cohort and those with CES-D 10 scores below 10 (the threshold for likely depression) at baseline. Recent IPV/A was independently associated with depressive symptoms both cross-sectionally and longitudinally. The longitudinal association was stronger among those not depressed at baseline. Implications for health care settings and workplace policies addressing IPV/A are discussed.     

Components of depressed mood in married men and women. The Center for Epidemiologic Studies' Depression Scale

The Center for Epidemiologic Studies' Depression Scale (CES-D) was developed to measure depressive symptoms in community populations. To be useful for epidemiologic studies of depression, the scale should measure the same thing in various subgroups. This study examines the psychometric properties of the CES-D among men and women, including its factor structure, reliability, and characteristics of its subscales. A national sample of 1,360 married men and women, collected in 1978, was used. Factor analysis produced four major factors in the CES-D: depressed affect, enervation , lack of positive affect, and interpersonal problems. These factors are generalizable across men and women with two exceptions--crying spells, which are a good indicator of depressed mood for women, do not indicate depressed mood for men; and feeling one's life is a failure is associated with depressed affect for women and with a lack of positive affect for men. The two items in the interpersonal factor (feeling that people dislike you and that people are unfriendly ) do not show the expected pattern of association with gender, since men have significantly more interpersonal symptoms than women. Women have more symptoms of depressed affect, enervation , and lack of positive affect.     

Prenatal Predictors of Maternal Attachment and Their Association with Postpartum Depressive Symptoms in Mexican Women at Risk of Depression

Objectives Although maternal attachment is an important predictor of infant developmental outcomes, little is known about its pre- and postnatal predictors. The purpose of this secondary data analysis is to assess several risk factors for maternal attachment at 6 months postpartum in a sample of Mexican women at risk of depression. The predictors included were prenatal depressive symptoms, pregnancy intendedness, partner relationship, social support, maternal history of childhood sexual abuse, and postpartum depressive symptoms. Methods A total of 156 pregnant women seeking antenatal care at three health centers were selected because they displayed depressive symptoms (CES-D?≥?16) or had previously suffered depression. Women were interviewed during pregnancy and at 6 months postpartum. A step-wise multivariate logistic regression was conducted to evaluate the pre- and postpartum risk factors for postpartum depression related to low maternal attachment. Results Pre- and postpartum depressive symptoms increased the risk of low maternal attachment by factors of 3.00 and 3.97, respectively, compared with women who did not present these symptoms; low level of adjustment with the partner increased the risk by a factor of 3.11, low social support by a factor of 2.90, and CSA by a factor of 2.77. Conclusions for practice Prevention programs during pregnancy to reduce depressive symptoms should strengthen strategies to promote maternal attachment by improving partner relations and increasing social support. However, evidence shows that such programs alone are insufficient, so direct interventions should also be implemented. Women with a history of childhood sexual abuse should be given additional attention during prenatal care.     

Mother-Infant Interaction, Life Events and Prenatal and Postpartum Depressive Symptoms Among Urban Minority Women in Primary Care

Objectives: Prenatal and postpartum depression are significant mental health problems that can have negative effects on mother-infant interactions. We examined the relationships among mother-infant interactions, depressive symptoms, life events, and breastfeeding of low-income urban African American and Hispanic women in primary care settings. Methods: Participants were 89 African American and Hispanic women who were part of a larger mental health intervention study conducted in community health centers. Questionnaire data on depression, as well as negative and positive life events, were collected during pregnancy and at three-months postpartum, while mother-infant interaction observations and breastfeeding practice were only collected at three-months postpartum. Results: The ratings of maternal behavior for ‘depressed’ mothers did not differ from ‘nondepressed’ mothers. Except for gaze aversion behavior, infants' behavior while interacting with their mothers did not differ by maternal depression level. Hierarchical regression analyses revealed that maternal positive life events positively predicted infant interactional summary ratings, while maternal negative life events were inversely associated with maternal interactional summary ratings. Conclusions: To improve services in primary care, perinatal screenings for depression can help identify those women most at risk. When follow-up use of structured diagnostic instruments is not possible or cost-effective, clinician assessment of severity of depression will determine women with clinical levels of depression. Reducing negative life events is beyond the control of women or clinicians but cognitive interventions to help women focus on positive life events can reduce the deleterious effects of depression on mothers and their infants.     

Maternal Visceral Adiposity by Consistency of Lactation

The purpose of this study was to examine the assocation between lactation and maternal visceral adiposity among US women who were on average 7 years postpartum. This cross-sectional analysis included 89 women who gave birth between 1997 and 2002, who did not have preeclampsia, prepregnancy hypertension or prepregnancy diabetes, and enrolled in The Women and Infant Study of Healthy Hearts (WISH). Computed tomography was used to assess abdominal adiposity. History of lactation was self-reported. Visceral adiposity was greater by 36.96 cm² (95% CI: 20.92,53.01) among mothers who never breastfed than mothers who breastfed for ≥3 months after every birth, even after adjustment for age, parity, years since last birth, site, socioeconomic, lifestyle, psychological, and family history variables, early adult BMI, and current BMI. Similarly, in fully adjusted models, mothers who breastfed any of their children for less than 3 months had 20.38 cm² (95% CI: 2.70, 38.06) greater visceral adiposity than mothers who consistently breastfed all their children for 3 or more months. This study found that 7 years postpartum visceral fat depots are significantly greater among mothers who lactated for less than 3 months after the birth of each of their children. These results provide a potential physiologic basis for prior findings that women who do not consistently breastfeed are at an increased risk of diabetes, cardiovascular disease, and the metabolic syndrome.
