Antenatal psychiatric morbidity in Maltese women

OBJECTIVE: There has been no empirical research on the occurrence of antenatal psychiatric morbidity in Maltese women. Epidemiological studies have shown that depressive episodes occur in 10-20% of pregnant women. Furthermore, studies have shown that antenatal psychiatric morbidity can adversely affect maternal and foetal well being. METHOD: A random sample of 239 pregnant women were interviewed at booking using a detailed sociodemographic history and the Revised Version of the Clinical Interview Schedule (CIS-R). The CIS-R was again administered at 36 weeks and at 8 weeks postpartum to 95.8% of the women. RESULTS: Among the 229 women interviewed the point prevalence of all psychiatric diagnosis was 19.2% and the point prevalence of antenatal depression and anxiety disorders was 14.8% and 4.4%, respectively, at 18.6 weeks of gestation. At 36 weeks of gestation, the point prevalence of depressive disorder was 10%. Two thirds of the antenatal depression remitted postpartum. CONCLUSION: A significant proportion of Maltese women suffer from psychiatric morbidity during pregnancy. Depressive disorders are the commonest morbidity in this study population. Given the scope of the morbidity and potential impact on obstetric and neonatal outcomes, early detection and treatment are recommended.     

Antenatal risk factors for postpartum depression: a synthesis of recent literature

Postpartum nonpsychotic depression is the most common complication of childbearing, affecting approximately 10-15% of women and, as such, represents a considerable health problem affecting women and their families. This systematic review provides a synthesis of the recent literature pertaining to antenatal risk factors associated with developing this condition. Databases relating to the medical, psychological, and social science literature were searched using specific inclusion criteria and search terms, in order to identify studies examining antenatal risk factors for postpartum depression. Studies were identified and critically appraised in order to synthesize the current findings. The search resulted in the identification of two major meta-analyses conducted on over 14,000 subjects, as well as newer subsequent large-scale clinical studies. The results of these studies were then summarized in terms of effect sizes as defined by Cohen. The findings from the meta-analyses of over 14,000 subjects, and subsequent studies of nearly 10,000 additional subjects found that the following factors were the strongest predictors of postpartum depression: depression during pregnancy, anxiety during pregnancy, experiencing stressful life events during pregnancy or the early puerperium, low levels of social support, and a previous history of depression. Critical appraisal of the literature revealed a number of methodological and knowledge gaps that need to be addressed in future research. These include examining specific risk factors in women of lower socioeconomic status, risk factors pertaining to teenage mothers, and the use of appropriate instruments assessing postpartum depression for use within different cultural groups.     

The association of psychosocial factors and obstetric history with depression in pregnant women: focus on the role of emotional support

Objective

Depression during pregnancy can negatively affect both maternal and fetal health. The benefits of early detection and treatment for antenatal depression have been emphasized. Therefore, we investigated risk factors for antenatal depression with a focus on emotional support.

Methods

We conducted a cross-sectional study of pregnant women (n= 1262) enrolled from the local division of a community mental health center. All subjects completed self-report questionnaires that assessed depressive mood, emotional support and other risk factors. Associations between antenatal depression and potential risk factors including emotional support were analyzed by logistic regression analysis.

Results

Antenatal depression was associated with various biopsychosocial correlates: unmarried state, low education, cigarette smoking, low income, familial history of depression, past history of depression, physical abuse history, sexual abuse history, premenstrual syndrome, primiparity and unplanned pregnancy. When the associations of emotional support with antenatal depression were specified by its resources, current emotional support from partner [odds ratio (OR)=2.26, 95% confidence interval (CI)=1.94–2.64] and mother (OR=1.43, 95% CI=1.26–1.62) and past experience for emotional support from mother (OR=1.52, 95% CI=1.32–1.74), but not from father significantly influenced depression during pregnancy.

Conclusions

The multidimensional biopsychosocial approach would be needed to identify and assess antenatal depression. Promoting emotional support from the partner, family member and, possibly, the health provider could be a protective effect against the development of antenatal depression.     

Gender, poverty, and postnatal depression: a study of mothers in Goa, India.

OBJECTIVE: This study described the natural history of depression in mothers who recently gave birth in a low-income country and to investigate the effect of risk factors, particularly related to infant gender bias, on the occurrence and outcome of depression. METHOD: The authors studied a group of pregnant mothers recruited during their third trimester of pregnancy from a district hospital in Goa, India. The mothers were interviewed at recruitment, 6-8 weeks, and 6 months after childbirth. Interview data included presence of antenatal and postnatal depression, obstetric history, economic and demographic characteristics, and gender-based variables (preference for male infant, presence of marital violence). RESULTS: Depressive disorder was detected in 59 (23%) of the mothers at 6-8 weeks after childbirth; 78% of these patients had had clinically substantial psychological morbidity during the antenatal period. More than one-half of the patients remained ill at 6 months after delivery. Economic deprivation and poor marital relationships were important risk factors for the occurrence and chronicity of depression. The gender of the infant was a determinant of postnatal depression; it modified the effect of other risk factors, such as marital violence and hunger. Depressed mothers were more disabled and were more likely to use health services than nondepressed mothers. CONCLUSIONS: Maternal and infant health policies, a priority in low-income countries, must integrate maternal depression as a disorder of public health significance. Interventions should target mothers in the antenatal period and incorporate a strong gender-based component.     

Racial differences in the prevalence of antenatal depression

Objective

This study examined whether there were racial/ethnic differences in the prevalence of antenatal depression based on Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, diagnostic criteria in a community-based sample of pregnant women.

Method

Data were drawn from an ongoing registry of pregnant women receiving prenatal care at a university obstetric clinic from January 2004 through March 2010 (N =1997). Logistic regression models adjusting for sociodemographic, psychiatric, behavioral and clinical characteristics were used to examine racial/ethnic differences in antenatal depression as measured by the Patient Health Questionnaire.

Results

Overall, 5.1% of the sample reported antenatal depression. Blacks and Asian/Pacific Islanders were at increased risk for antenatal depression compared to non-Hispanic White women. This increased risk of antenatal depression among Blacks and Asian/Pacific Islanders remained after adjustment for a variety of risk factors.

Conclusion

Results suggest the importance of race/ethnicity as a risk factor for antenatal depression. Prevention and treatment strategies geared toward the mental health needs of Black and Asian/Pacific Islander women are needed to reduce the racial/ethnic disparities in antenatal depression.     

Antenatal thyroid correlates of postpartum depression

We previously found significantly higher T3-resin uptake and nearly significantly lower total thyroxine concentrations at 38 weeks of pregnancy in women with higher postpartum depression ratings. This study further examined the relationship between thyroid status during late pregnancy and antenatal and postpartum depression scores. Thyroid measures were obtained at 32-35, 36, and 37 weeks of pregnancy in 31 women with normal range thyroid hormone levels. Subjects rated their mood at these antenatal time points and every other week between postpartum weeks 2 and 24 on the Edinburgh Postnatal Depression Scale and the Beck Depression Inventory. Mean antenatal thyroxine concentrations and free thyroxine indices correlated significantly and negatively with mean depression scores during each of three postpartum time periods (postpartum weeks 2-6, 14-18, 20-24). Women with total and free thyroxine concentrations that were, respectively, <10.1 microg/dl and <1.06 ng/dl at all three antenatal time points had significantly higher mean depression scores during all postpartum time periods. The fraction of subjects with pregravid major or minor depression history that was in the low antenatal thyroid group was significantly higher than the fraction of subjects with negative history (5/6 vs. 7/25). Women with antenatal total and free thyroxine concentrations in the lower euthyroid range may be at greater risk of developing postpartum depressive symptoms. Study of the relationships with antenatal thyroid status may provide new insights into the pathophysiology of perinatal mood disturbances.     

Screening of antenatal depression in Pakistan: risk factors and effects on obstetric and neonatal outcomes

Introduction: To determine the frequency of probable antenatal depression (AD) in pregnant women in third trimester, assess the risk factors and its impact on obstetric and neonatal outcomes in a developing country. Methods: A prospective study conducted in a tertiary care hospital in Lahore from March 2007 to July 2007. Two hundred and thirteen pregnant women in the third trimester, attending the Gynecology Outpatient Clinic were recruited. They were assessed by a semistructured questionnaire to gather demographic details and various risk factors for AD. AD was assessed by Edinburgh Postnatal Depression Scale. All women were followed until delivery to determine their obstetric and neonatal outcomes. Results: Out of 213 women, 91 (42.7%) scored above the cut‐off for AD. More women with depression reported problems in their marriage, problems with parents/in laws, history of domestic violence, past history of psychiatric problems and history of postnatal depression. In the obstetric risk factors history of previous miscarriages, stillbirths, and complications in previous pregnancy reached statistical significance. Thirty‐seven (17.3%) women were lost to follow up. Women with AD had more obstetric complications during delivery. Babies of mothers with AD had significantly low birth weight, as well as low mean APGAR scores at 1 and 5 minutes following birth. Discussion: AD is a common problem in Pakistani Society. In view of the risk factors and adverse outcomes associated with depression during pregnancy, there is need for close liaison between Gynaecologists and Psychiatrists in managing these patients.     

Effectiveness of Antenatal Emotional Self‐Management Training Program in Prevention of Postnatal Depression in Chinese Women

PURPOSE: This study aimed to study the effectiveness of an emotional self‐management training program to antenatal women in the prevention of postnatal depression. DESIGN AND METHODS: The sample comprised 240 women who were at 32 weeks antenatal. They were randomly assigned into the intervention group and the control group. FINDINGS: On completion of the program, the intervention group reported significantly lower mean Patient Health Questionnaire‐9 and Edinburgh Postnatal Depression Scale scores than the control group. Fewer participants from the intervention group were diagnosed as having postnatal depression using the Structured Clinical Interview for DSM‐IV. PRACTICE IMPLICATIONS: An antenatal emotional self‐management training that may lower the risk of developing postnatal depression among Chinese women is recommended.     

Antenatal psychosocial risk factors and depression among women living in socioeconomically disadvantaged suburbs in Adelaide, South Australia

OBJECTIVE: This study reports the prevalence of psychosocial risk factors and the incidence of depression in women presenting for their first antenatal visit at a general hospital in a socioeconomically deprived area. We also investigated the association between specific psychosocial risk factors and antenatal depression. METHOD: Four hundred and twenty one women completed the Antenatal Psychosocial Questionnaire (APQ) and the Edinburgh Postnatal Depression Scale (EPDS). Logistic regression analysis was used to identify psychosocial risk factors predictive of EPDS caseness. RESULTS: 88% of women endorsed at least one psychosocial risk factor. 35.6% had been abused as children, 34.9% had suffered recent major life stresses, 24.5% had thoughts of self harm, 8% admitted to recently hitting or hurting someone in anger and 5.6% had been victims of violence since becoming pregnant. The incidence of depression, measured using an EPDS cut-off score of 10 or more, was 29.7%. The questionnaires were generally acceptable, apart from questions about drug and alcohol abuse which were not completed by one in five subjects. Factors associated with an increased risk of antenatal depression were being hit by someone since becoming pregnant, having recently hit someone else in anger, obsessional traits, previous feelings of depression and anxiety, and requiring both past and current treatment for emotional problems. Protective factors were having someone to talk to and feeling confident. CONCLUSION: Our findings suggest that women birthing at the LMHS are a very vulnerable group. Violence (either by or towards the pregnant women) was the strongest predictor of antenatal depression and may be under recognized. Antenatal screening for psychosocial risk factors and depression was useful and was well accepted by the women and the clinic staff. It is important that appropriate services are available once women at risk are identified.     

Obstetric risk factors for postnatal depression in urban and rural community samples

OBJECTIVE: The objective of this study was to examine obstetric risk factors for postnatal depression in an urban and rural community sample, with concurrent consideration of personality, psychiatric history and recent life events. METHODS: This was a prospective study with women planning to give birth in one of the four participating hospitals recruited antenatally. Obstetric information was obtained from the New South Wales Midwives Data Collection, completed shortly after delivery. Personality, psychiatric history and life-events information were obtained from a questionnaire, administered within 1 week postpartum. Depression status was assessed at 8 weeks postpartum using the Edinburgh Postnatal Depression Scale. RESULTS: Complete data were obtained from 490 women. Several non-obstetric risk factors for the development of postnatal depression at 8 weeks postpartum were reported including: sociodemographic (up to technical college level education, rented housing, receiving a pension/benefit), personality (those who described themselves as either nervy, shy/selfconscious, obsessional, angry or a worrier), psychiatric history (familial history of mental illness, personal history of depression or anxiety or a history of depression in the participant's mother) and recent life-events (major health problem, arguments with partner and friends/relatives). None of the obstetric variables were significantly associated with increased risk for postnatal depression, but several showed marginally significant increases (multiparous women, antepartum haemorrhage, forceps and caesarean section deliveries). CONCLUSIONS: The results emphasize the importance of psychosocial risk factors for postnatal depression and suggest that most obstetric factors during pregnancy and birth do not significantly increase risk for this depression. Early identification of potential risk for postnatal depression should include assessment of sociodemography, personality, psychiatric history and recent life events, as well as past and present obstetric factors.     

Antenatal depression and children’s developmental outcomes: potential mechanisms and treatment options

During the last decade there has been increased recognition of the prevalence of antenatal depression as well as an expansion in research examining the impact of maternal mood during pregnancy on offspring development. The aim of this review was to summarise the theoretical underpinnings and empirical evidence regarding the impact of antenatal depression on children’s developmental outcomes. Biological mechanisms hypothesised to account for an association between antenatal depression and adverse offspring outcomes are first identified including the functioning of the prenatal Hypothalamic Pituitary Adrenal (HPA) axis and epigenetic processes. A systematic literature search is then conducted of studies examining the impact of antenatal depression on child development. In general, studies examining associations between antenatal depression and offspring temperament, cognitive and emotional outcomes reveal either no effect of the prenatal environment or small effects that often attenuate following adjustment for other antenatal and postnatal risk factors. In contrast, an independent effect of antenatal depression on children’s conduct problems and antisocial behaviour is a well-replicated finding. There is emerging evidence that exposure to depression during pregnancy impacts negatively on offspring biology, although the findings are complex and require replication. Psychological and pharmacological treatments of antenatal depression are then reviewed, considering whether antidepressant medication exerts harmful effects on the foetus. We close by proposing that antenatal depression is an early marker of a developmental cascade to future mental health problems for both mothers and offspring.     

Mood changes, obstetric experience and alterations in plasma cortisol, beta-endorphin and corticotrophin releasing hormone during pregnancy and the puerperium

The relationships between mood change, obstetric experience and alterations in plasma cortisol, beta-endorphin (beta-EP) and corticotrophin-releasing hormone (CRH) were examined in a prospective study of 97 primiparous Australian women. Psychological measures were administered between the 28th week of pregnancy and the 3rd postnatal month, including the Profile of Mood States (POMS) and the Montgomery Asberg Depressive Rating Scale (MADRS). Blood samples were collected for cortisol, beta-EP and CRH assay on most of these occasions and during labour. Factor analysis was used to identify key subsets of psychological variables for use in the subsequent analyses. 'Mood disturbance' and 'tiredness' factors peaked at 38 weeks' gestation, while 'difficulty falling asleep' was greatest around the time of birth. Cortisol, beta-EP and CRH concentrations rose significantly as pregnancy advanced and peaked at birth; plasma CRH correlated with plasma cortisol (r = 0.54) and beta-EP (r = 0.32). Women with the highest 'mood disturbance' and MADRS depression scores at 28 weeks' gestation received significantly more pain relief during labour. Those women whose mood deteriorated from 38 weeks' gestation to postnatal day 2 had larger falls in plasma beta-EP after delivery (p less than 0.01) than those women whose mood improved or remained constant. Women in this mood-deteriorated subgroup also had significantly higher MADRS depression scores at 3 months (p less than 0.01). Mild antenatal depression (MADRS greater than 13) occurred in 5.2% of women and mild postnatal depression in 4.7%. Overall, these data suggest a role for circulating CRH in the regulation of maternal cortisol secretion and significant relationships between maternal postnatal mood states and beta-EP and between antenatal mood states and obstetric events.     

Prevalence and correlates of depression in late pregnancy among Nigerian women

The objectives of this study were to estimate the prevalence of depressive disorder in late pregnancy in a group of Nigerian women and to examine the associated factors. One hundred and eighty women in late pregnancy completed a questionnaire on sociodemographic and obstetrical details. They also completed the Edinburgh Postnatal Depression Scale (EPDS). A proportion of them were then assessed for the DSM-IV diagnosis of depressive disorder. Fifteen (8.3%) women met the current (2 weeks) DSM-IV diagnosis of depressive disorder. The factors independently associated with depression included being single [odds ratio (OR)=16.67, 95% confidence interval (CI)=3.17-87.76], divorced/separated (OR=11.11, 95% CI=1.55-19.65), polygamous (OR=3.92, 95% CI=0.94-16.33), and having a previous history of stillbirth (OR=8.00, 95% CI=1.70-37.57) and perceived lack of social support (OR=6.08, 95% CI=1.42-26.04). Depression is common in late pregnancy among Nigerian women, with the significant correlates including mainly social and family factors. Such factors should be considered when planning health care services or formulating a predictive model. Interventions aimed at reducing the occurrence of antenatal depression need further research.     

Predictors and correlates of high levels of depression and anxiety symptoms among children at age 10

OBJECTIVE: To identify factors that predict or are correlated with symptoms of depression and anxiety in 10-year-olds. METHOD: Women and their offspring were followed from the fourth prenatal month through 10 years. There were 636 mother-child pairs at 10 years, a follow-up rate of 83% of the birth cohort. Cognitive, psychological, sociodemographic, and environmental factors were measured at each phase. High depression and anxiety were defined as having a number of symptoms >1 SD above the mean for each measure. These measures were combined to represent high depression and/or anxiety (D/A) at 10 years of age. RESULTS: Predictors from the prenatal period of D/A at 10 years were more maternal depression symptoms, African American race, less social support, greater household density, and prenatal marijuana exposure. From 18 months through 6 years, lower child IQ, child injuries at age 3, and attention problems predicted symptoms of D/A at age 10. Across all study phases, lower child IQ, household density during pregnancy, attention problems, early childhood injuries, and prenatal marijuana exposure predicted D/A. Maternal psychological and sociodemographic factors were not significant in the final model. CONCLUSIONS: Factors from gestation and early childhood predict high symptom levels of depression and anxiety at age 10. When gestational exposure, early environmental factors, and child characteristics were considered, maternal depression and socioeconomic status were not significantly associated with early onset D/A. Marijuana exposure during gestation marginally predicted depression/anxiety at age 10.     

Poor maternal care and high maternal body mass index in pregnancy as a risk factor for schizophrenia in offspring

OBJECTIVE: We investigated whether antenatal factors in mothers would increase the risk of schizophrenia in the offspring, and also examined any relationship between these factors and histories of obstetric complications (OCs). METHOD: Using the Mother and Child Health Handbooks of 52 patients with schizophrenia and 284 healthy subjects, we evaluated the risk-increasing effects of the frequency of antenatal care visits and mothers' body mass index (BMI) at both early and late pregnancy. RESULTS: In logistic regression analysis, there was a significant association between the number of antenatal care visits and the risk of the disorder; an increase in a unit of visits corresponds to a reduction of the risk by 12%. We also found a 24% increase in the risk with a one-unit increase of BMI at the early pregnancy, and a 19% increase at the late pregnancy. These antenatal factors were found to contribute, in part, to an excess of OCs in individuals with schizophrenia. CONCLUSION: Poor maternal care during pregnancy and comparatively high maternal BMI especially at early pregnancy may cause a predisposition to schizophrenia in the offspring.     

Depressive symptomatology in pregnancy

Abstract This is a two-part study looking at depressive symptomatology in pregnancy in Singaporean women, and the associated demographic, and bio-psychosocial characteristics of women at risk of depressive illness. We validated the 10-item Centre for Epidemiological Studies-Depression scale amongst pregnant women, and then used this tool to identify depressive states in an antenatal cohort from the national maternity hospital. Amongst the sample population, the rate of depressive disorders is as high as one in five in the antepartum. The risk factors in the antepartum include being young, history of smoking, having past and current obstetric complications, frequent alcohol use and having medical problems.     

Characteristics, treatment patterns, and outcomes of persistent depression despite treatment in primary care

We examine the sociodemographic and clinical characteristics of depressed primary care patients who receive at least minimal standards of evidence-based treatment, comparing those who remain depressed with those who recover; and their subsequent treatment patterns and other outcomes. We used observational data from a subset of 542 treated patients participating in a group-level randomized controlled trial of quality improvement interventions for depression conducted in six managed care organizations. Nonresponse to treatment was defined as having at least minimally appropriate treatment for at least two of three 6-month periods but continuing to have probable depression. Our definitions of depression and appropriate treatment are broader than those used in clinical trials, but relevant to primary care settings. Many of the factors predictive of treatment resistance in clinical trials predict nonresponse to guideline concordant care among diverse primary care, depressed patients. The main unique predictors of nonresponse to treatment include a clinical factor (suicide ideation) requiring clinician assessment and intervention, a social/economic factor (unemployment) usually not addressed by medical interventions, and medication nonadherence. Nonresponders used more adjunctive therapies and combination medications, suggesting clinicians and patients were searching for solutions. High rates of service use and poor outcomes emphasize the urgency of new research to find solutions for these patients.     

Antenatal Depression Strongly Predicts Postnatal Depression in Primary Health Care

Objective: To estimate the association between antenatal and postnatal depression and to examine the role of socioeconomic conditions in the risk of postnatal depression. Methods: A prospective cohort study, conducted between May 2005 and January 2006, with 831 pregnant women recruited from primary care clinics in the public sector in the city of São Paulo, Brazil. The presence of antenatal and postnatal depression was measured with the Self Report Questionnaire (SRQ-20). Sociodemographic and socioeconomic characteristics and obstetric information were obtained through a questionnaire. Crude and adjusted risk ratios (RR), with 95% CI, were calculated using a Poisson regression. Results: The prevalence of postnatal depressive symptoms was 31.2% (95%CI: 27.8-34.8%). Among the 219 mothers who had depressive symptoms, nearly 50% had already shown depressive symptoms during pregnancy. Women who had antenatal depression were 2.4 times more likely to present with postnatal depression than were women who did not have such symptoms during pregnancy. In the multivariate analysis, higher scores for assets (RR: 0.76, 95% CI 0.61-0.96), higher education (RR: 0.75 95%CI 0.59-0.96), daily contact with neighbors (RR: 0.68, 95%CI 0.51-0.90) and antenatal depression (RR: 2.44, 95%CI 1.93-3.08) remained independently associated with postnatal depression. Conclusions: Antenatal and postnatal depression are highly prevalent in the primary care setting.     

Single motherhood versus poor partner relationship: outcomes for antenatal mental health

OBJECTIVE: In the transition to parenthood, lack of social support significantly impacts on maternal mood. This paper compares the influence of single-mother status and level of partner support in a partnered relationship, on antenatal emotional health. METHODS: Antenatal demographic, psychosocial and mental health data, as determined by Edinburgh Postnatal Depression Scale (EPDS) score, were collected from 1578 women. The association between these variables, and marital status, was investigated using logistic regression. RESULTS: Sixty-two women (3.9%) were identified as single/unpartnered. Elevated EPDS scores (>12) were found in 15.2% (240/1578) of the total cohort and 25.8% (16/62) of the single/unpartnered women. EPDS scores were significantly lower for single/unpartnered women than for women with unsupportive partners (8.9+/-5.3 vs 11.9+/-6.5, p<0.001). Compared to the partnered cohort, single/unpartnered women were more likely to have experienced >or=2 weeks of depression before the current pregnancy (p<0.05), a previous psychopathology (p<0.001), emotional problems during the current pregnancy (p<0.01) and major life events in the last year (p<0.01). Binary logistic regression modelling to predict antenatal EPDS scores suggests that this is mediated by previous psychiatric history (p<0.001) and emotional problems during pregnancy (p=0.02). CONCLUSION: Women in a partnered-relationship with poor partner-derived support were at an increased risk of elevated antenatal EPDS scores compared to single/unpartnered women. A previous history of depression and current emotional problems, rather than single mother status, were significant risk factors for elevated EPDS scores. The present study reiterates the contribution of psychosocial risk factors as important mediators of antenatal emotional health.     

Association between antenatal depression and low birthweight in a developing country

OBJECTIVE: There is a high prevalence of depression in south Asian women. We aimed to examine the association between antenatal depression and low birthweight (LBW) in infants in a rural community in Rawalpindi, Pakistan. METHOD: A total of 143 physically healthy mothers with ICD-10 depression in the third trimester of pregnancy and 147 non-depressed mothers of similar gestation were followed from birth. Infant weight was measured and information collected on socioeconomic status, maternal body-mass index and sociodemographic factors. RESULTS: Infants of depressed mothers had lower birthweight (mean 2910 g) than infants of non-depressed mothers (mean 3022 g). The relative risk for LBW (< or =2500 g) in infants of depressed mothers was 1.9 (95% CI 1.3-2.9). The association remained significant after adjustment for confounders by multivariate analyses. CONCLUSION: Low birthweight is a major public health problem in developing countries. Maternal depression during pregnancy predicts LBW. Interventions aimed at maternal depression may help improve infant outcomes.
