Racial Differences in the Association Between Maternal Antenatal Depression and Preterm Birth Risk: A Prospective Cohort Study.

ABSTRACT:

Background

In the United States, racial/ethnic disparities in preterm birth (PTB) are well documented, but explanations for why the disparity persists remain to be fully explored. We examined racial/ethnic differences in the association of maternal antenatal depression with PTB (<37 completed weeks of gestation) risk.

Methods

In a prospective cohort study, participants (n?=?2073) included non-Hispanic (NH) black, NH white, Asian, and Hispanic women who received prenatal care at a university obstetric clinic January 2004-March 2010, and delivered at the university's hospital. We obtained data from self-reported questionnaires and electronic medical records. We assessed antenatal depression using the Patient Health Questionnaire-9 and self-reported antenatal antidepressant medication use. Poisson regression models were used to estimate the association between antenatal depression and PTB risk, within strata of race/ethnicity.

Results

NH black (risk ratio [RR]?=?1.89; 95% confidence interval [CI]: 0.94, 3.80), NH white (RR?=?1.58, 95% CI: 1.04, 2.39), and Asian (RR?=?2.06; 95% CI: 0.69, 6.13) women with antenatal depression were at increased risk for delivering preterm infants, compared with women without antenatal depression, although the associations were statistically significant only among NH white women. There was no evidence of an association between antenatal depression and risk of PTB among Hispanic women (RR?=?0.96; 95% CI: 0.28, 3.25); p-value for interaction?=?0.81.

Conclusion

Our findings suggest race-specific associations of antenatal depression with an increased risk of delivering a preterm infant, supporting the importance of considering race/ethnicity when examining risk factors for health outcomes.

Project description:In Pakistan, incidence of antenatal depression ranges from 18 to 80 %, which goes undiagnosed, resulting in maternal and neonatal implications. The current study aimed to examine the association of antenatal depression with maternal dietary intake and neonatal outcome.A hospital-based, prospective cohort study was conducted on 94 middle class antenatal attendees coming to a tertiary care hospital in Lahore, Pakistan at the beginning of second trimester. Participants fulfilling eligibility were enrolled consecutively after taking written informed consent. Exposure group was identified by Edinburgh Postnatal Depression Scale (EPDS) and cohort members were followed till after delivery. Maternal dietary intake was assessed by 24-h Recall and Food Frequency Checklist, while neonatal outcome was identified through patient files before discharge. Data on potential confounders was collected. Loss to follow up was 13 % (82/94). Data was collected from April-September 2013. Results for 82 participants were analyzed using SPSS version 21.EPDS screened 35/82 (43 %) eligible antenatal attendees as depressed, out of which 16/35 (20 %) were severely depressed and 19/35 (23 %) were moderately depressed. Incidence of poor maternal dietary intake was more in females with antenatal depression. Antenatal depression increased the risk of poor Healthy Eating Index (RR = 2.58, C.I 1.60-5.23, AR = 62 %), carbohydrate <175 gm (RR = 1.188, CI 0.836-1.688, AR = 15 %), protein <71 gm (RR = 1.343, CI 1.059-1.703, AR = 26 %) and fat <55 gm (RR = 2.954, CI 1.612-5.416, AR = 67 %) Incidence of neonatal outcomes included, Fetal Growth Retardation (RR = 2.70, C.I 0.69-3.70, AR = 60 %), preterm birth (RR = 1.60, C.I 0.72-2.45, AR = 54 %), low Apgar score (RR = 2.70, C.I 0.69-3.70, AR = 60 %) and Low Birth Weight (RR = 0.56, C.I 0.93-1.39, AR = -44 %).Antenatal women with depression developed poor dietary intake and had increased incidence of Fetal Growth Retardation, preterm birth and low Apgar score, but not of Low Birth Weight.

Project description:BackgroundThe association between maternal obesity and preterm birth remains controversial and inconclusive, and the effects of gestational diabetes mellitus (GDM) and preeclampsia (PE) on the relationship between obesity and preterm birth have not been studied. We aimed to clarify the relationship between prepregnancy body mass index (BMI) and the phenotypes of preterm birth and evaluate the mediation effects of GDM and PE on the relationship between prepregnancy BMI and preterm birth.MethodsWe conducted a prospective cohort study of 43,056 women with live singleton births from 2017 through 2019. According to the WHO International Classification, BMI was classified as underweight (BMI < 18.5 kg/m2), normal weight (BMI 18.5-25 kg/m2), overweight (BMI 25-30 kg/m2) and obese (BMI ≥30 kg/m2). Preterm birth was defined as gestational age less than 37 weeks (extremely, < 28 weeks; very, 28-31 weeks; and moderately, 32-36 weeks). The clinical phenotypes of preterm birth included spontaneous preterm birth (spontaneous preterm labor and premature rupture of the membranes) and medically indicated preterm birth. We further analyzed preterm births with GDM or PE. Multivariable logistic regression analysis and causal mediation analysis were performed.ResultsRisks of extremely, very, and moderately preterm birth increased with BMI, and the highest risk was observed for obese women with extremely preterm birth (OR 3.43, 95% CI 1.07-10.97). Maternal obesity was significantly associated with spontaneous preterm labor (OR 1.98; 95% CI 1.13-3.47), premature rupture of the membranes (OR 2.04; 95% CI 1.08-3.86) and medically indicated preterm birth (OR 2.05; 95% CI 1.25-3.37). GDM and PE mediated 13.41 and 36.66% of the effect of obesity on preterm birth, respectively. GDM mediated 32.80% of the effect of obesity on spontaneous preterm labor and PE mediated 64.31% of the effect of obesity on medically indicated preterm birth.ConclusionsMaternal prepregnancy obesity was associated with all phenotypes of preterm birth, and the highest risks were extremely preterm birth and medically indicated preterm birth. GDM and PE partially mediated the association between obesity and preterm birth.

Project description:BACKGROUND:Low birthweight (LBW) and preterm birth (PB) remain the leading cause of morbidity and mortality in neonates worldwide. The aim of this study was to identify maternal demographic and antenatal factors associated with PB and LBW among low socio-economic communities. METHODS:Pregnant women (n?=?1099) were recruited in the first trimester into the Mother and Child in the Environment (MACE) birth cohort in Durban, South Africa. Maternal factors such as demographic information, health status, residential area, occupational, personal and environmental smoking and biomass fuel use were obtained through standardised interviews, while clinical status was obtained in each trimester and antenatal information on HIV status and treatment, syphilis and conditions such as pregnancy induced hypertension, diabetes etc. was extracted from the antenatal assessments. Key outcomes of interest were preterm birth and low birthweight. The latter data was obtained from the clinical assessments performed by midwives at delivery. Logistic regression models identified factors associated with PB and LBW. RESULTS:Of the 760 live births, 16.4 and 13.5% were preterm and LBW, respectively. Mothers who delivered by caesarean section had an increased odds of having LBW babies (Adjusted odds ratio (AOR): 1.7; 95% CI: 1.1-2.7) and PB (AOR: 1.7, 95% CI: 1.1-2.7) versus normal vaginal deliveries. Mothers >?30?years (AOR: 1.8, 95% CI: 1.1-2.9) and current smokers (AOR: 2.7, 95% CI: 1.3-5.8) had an increased odds of having PB babies. Compared to younger mothers and non-smokers respectively. An effect of PB and LBW was seen among mothers with high BMI (25.0-29.9?kg/m2) (PB: AOR: 0.5, 95% CI: 0.3-0.9 and LBW: AOR: 0.5, 0.5, CI: 0.3-0.8), and obese BMI (>?30?kg/m2) (PB: AOR: 0.5, 95% CI: 0.3-0.9 and LBW: AOR: 0.4, CI: 0.2-0.7). Maternal HIV (PB AOR: 1.4 and LBW AOR: 1.2) and history of sexually transmitted infections (PB AOR: 2.7 and LBW AOR: 4.2) were not statistically significant. CONCLUSION:Maternal age, cigarette smoking and caesarean delivery were associated with LBW and PB. Findings highlight the need of maternal health interventions to improve new-born health outcomes.

Project description:BackgroundWe utilised data from the 2015 Pelotas Birth Cohort, a large prospective cohort in southern Brazil, to examine the association of moderate and severe antenatal depression with child birth outcomes and explore interactions with sociodemographic characteristics.MethodsData was available for n = 3046 participants and their infants. We measured antenatal depression using the Edinburgh Postnatal Depression Scale (EPDS, ≥13 for moderate and ≥17 for severe depression). Outcome measures included gestational age, birth weight, length and head circumference, using the Intergrowth-21st standards. We controlled for known confounders including obstetric risk.ResultsWe did not find differences in childbirth outcomes by maternal depression status for participants with at least moderate depression, although there was an increased risk for female offspring to be small for gestational age (SGA, OR 2.33[1.37,3.97]). For severe depression (EPDS≥17) we found an increased risk for lower APGAR scores (OR 1.63[1.02,2.60]) and being SGA (OR 1.77[1.06,2.97], with an increased risk for female offspring in particular to be in lower weight centiles (-10.71 [-16.83,-4.60]), to be SGA (OR 3.74[1.89, 7.44]) and in the lower 10th centile for length (OR 2.19[1.25,3.84]).Limitationsinclude the use of a maternal report questionnaire to ascertain depressive symptoms.ConclusionsIn this recent large longitudinal cohort in Brazil we did not find independent effects of depression on adverse birth outcomes or interactions with sociodemographic characteristics. We found an increased risk of being SGA for female offspring of women with moderate and severe depression, in line with other research suggesting females may be more susceptible to antenatal disturbances.FundingThis work was supported by the Wellcome Trust, United Kingdom (095582), the Brazilian National Research Council (CNPq) and the Coordination for the Improvement of Higher Education Personnel (CAPES).
