Mediterranean Diet Adherence and Depressive Symptoms among a Nationally Representative Sample of Pregnant Women in the United States

BACKGROUND

Prenatal depression affects ∼12% of pregnant women in the United States and is associated with an increased risk of adverse birth outcomes and maternal mortality. Adherence to a healthy dietary pattern may reduce and/or protect against depressive symptoms.

OBJECTIVES

To investigate the relationship between adherence to a Mediterranean diet and depressive symptoms among pregnant women in the United States.

METHODS

We used data from the National Health and Nutrition Examination Survey (2005-2018, N = 540) and included pregnant women aged 18-44 y with a positive urine pregnancy test. The Mediterranean diet score (aMED) was calculated from 1 24-h recall; aMED typically ranges from 0-9, but in these analyses, it ranged from 0-8 because alcohol was not included. The aMED score was dichotomized as high (>3) compared with low (≤3). The Patient Health Questionnaire-9 (PHQ-9), which measures depressive symptoms, was dichotomized as lower compared with higher (PHQ-9 score ≥10), based on the clinical cutoff for patient referral. Our primary model employed logistic regression to investigate the association between aMED adherence and high depressive symptoms when controlling for socio-demographics (age, racial/ethnicity, education, poverty, and relationship status), total calories, and prepregnancy body mass index (kg/m2). We also modeled the PHQ-9 score as a continuous variable using a random-effects model.

RESULTS

About 5% of pregnant women had moderate to severe depressive symptoms, and 45% were highly adherent to a Mediterranean diet. Higher adherence to a Mediterranean diet was associated with lower odds of depressive symptoms (odds ratio: 0.31, 95% confidence interval: 0.10, 0.98). Results were not significant for the continuous PHQ-9 score (β: -0.30; 95% confidence interval: -0.90, 0.30).

CONCLUSIONS

Adherence to a Mediterranean diet may have the potential to lower depressive symptoms among pregnant women; however, these results should be interpreted with caution. Nevertheless, considering the public health significance of promoting mental wellness among pregnant women, this relationship merits further examination using experimental designs.

Feasibility and Acceptability of a Mindfulness-Based Smartphone App among Pregnant Women with Obesity

Maternal obesity is associated with an increased risk for prenatal depressive symptoms. Mindfulness-based interventions (MBIs) have been shown to reduce the risk of prenatal depression. This pilot study assesses the feasibility and acceptability of a smartphone-based MBI among pregnant women with obesity, and its potential for improving maternal mental and behavioral health outcomes. Five second-trimester pregnant women with a prepregnancy body mass index > 30 kg/m² participated in a 30-day audio-guided mindfulness practice using the Headspace app. All participants engaged in the pregnancy module, while three concurrently engaged in the mindful eating module. Daily engagement with the app was tracked and a post-trial survey assessed maternal acceptability. Validated pre- and post-trial questionnaires explored changes in perceived stress, anxiety, depression, and eating habits. All participants completed the study with varying levels of adherence to the prescribed daily practice; the average number of days of engagement was 23/30 (77%) for the pregnancy module and 20/30 (67%) for the mindful eating module. All subjects reported some degree of perceived benefit, and none reported negative experiences. Trends were observed for improvements in maternal mental wellbeing and eating behaviors. This pilot study shows that a smartphone-based MBI is feasible, acceptable, and perceived to provide benefit among pregnant women with obesity.

Prenatal depression moderates the relationship between maternal trauma exposure and cortisol production and predicts breastfeeding behavior

Trauma exposure is associated with many negative outcomes for women during the prenatal and postnatal periods, including increased antenatal depressive symptomatology and dysregulation of the body's stress responses. Trauma exposure and its consequences are also tied to women's ability to breastfeed, a crucial component in maternal and infant health. Cortisol is biologically relevant to the breastfeeding process, and is also associated with depressive symptoms, which may interfere with women's ability to successfully maintain breastfeeding. However, no known studies integrate prenatal cortisol and depressive symptom severity into models of relations between trauma exposure and breastfeeding, particularly while considering trauma timing and type. Therefore, the current study did so using data from a historically understudied sample. Data were drawn from a community sample of 96 women residing in a health professional shortage area for mental health and primary care. Participants provided data during their third trimester of pregnancy and 6 months postpartum. Three moderated mediation models were tested to explore relations among history of trauma, breastfeeding, and related variables. Increased prenatal depressive symptoms were related to elevated prenatal cortisol awakening response, as well as moderated the relationship between interpersonal trauma exposure and greater prenatal cortisol awakening response. A significant positive correlation was also found between trauma and prenatal depressive symptoms, as well as a significant negative correlation between prenatal depressive symptoms and breastfeeding frequency. Results suggest that subclinical prenatal depressive symptoms may interact with trauma symptoms to affect women's stress responses and breastfeeding behaviors, and that women at risk for breastfeeding difficulty may be identified prenatally.

Risk factors of paternal perinatal depression during the COVID-19 pandemic in Japan

PURPOSE

The study aims to investigate risk factors of paternal perinatal depression during the COVID-19 pandemic.

METHODS

We conducted an online cross-sectional study of 473 prenatal fathers and 1246 postnatal fathers in August 2021. We applied a modified Poisson regression to estimate relative risk ratios of possible factors for paternal perinatal depression (measured by Edinburgh Postnatal Depression Scale), sequentially introducing the following factors into the model: individual factors, interpersonal factors, obstetric/pediatric factors, and service utilization factors.

RESULTS

Prenatal fathers with the following risk factors were at an increased risk for having depressive symptoms: adverse childhood experiences (risk ratio; RR 1.61), past depression (RR 1.63), fear of COVID-19 (RR 2.09), lower social support (RR 1.91), low family resources (RR 1.95), and intimate partner violence (IPV) victimization (RR 1.29). Postnatal fathers having the following risk factors were at an increased risk for having depressive symptoms: past depression (RR 1.67), fear of COVID-19 (RR 1.26), low family resources (RR 1.85), IPV victimization. (RR 1.18), and preterm birth (RR 1.18).

CONCLUSION

The study showed risk factors such as past history of depression, high fear of COVID-19, low family functionality, and IPV victimization were associated with perinatal depressive symptoms. The findings should contribute to future directions of interventions for paternal perinatal mental health.

In her shoes: Partner reflective functioning promotes family-level resilience to maternal depression

Parental depression has significant implications for family functioning, yet much of the literature does not consider family-level dynamics in investigating individual, parenting and child outcomes. In the current study we apply a new index of couple-level support, partner reflective functioning (RF), or the romantic partner's ability to consider how the partner's mental states can guide behavior, to study familial resiliency in the face of prenatal parental depression among first-time parents. We investigate how partner RF buffers the association between prenatal parental depression and outcomes of postnatal parental depression, parenting style, and child effortful control. Maternal and paternal depression were measured in 91 primiparous couples during the sixth month of pregnancy and parental depression, partner RF, parental RF at 6 months postnatally. Outcomes of parental depression, permissive parenting, and children's effortful control were assessed 24 months postnatally. Results indicate that average and high levels of paternal partner (not parental) RF attenuate risk for maternal postnatal depression, maternal permissive parenting, and deficits in child effortful control. Implications are discussed from a family systems approach.

Preconception menstrual cycle disorder and antenatal depression: a cross-sectional study with prerecorded information

OBJECTIVES

This study aimed to evaluate the association between pre-pregnancy menstrual cycle characteristics (i.e. cycle-length variability and cycle length) and antenatal depression.

METHODS

This study retrieved the data from the baseline survey of the randomized controlled trial with pregnant women at 16-20 weeks gestation who used a pregnancy tracking app. The antenatal depression was assessed using the Edinburgh Postnatal Depression Scale (EPDS) at 16-20 weeks gestation, and the cutoff point of 10/11 was adopted. Pre-conceptional menstrual cycle information was obtained via a prerecorded period tracking app. Cycle-length variability was defined as the average difference in the lengths between cycles, dichotomized into regular (≤6 days) and irregular (>6 days). Cycle length was coded as a categorical variable: <25 days, 25-26 days, 27-29 days (regular), 30-31 days, 32-33 days, and 34+ days. The associations of cycle disorders with EPDS scores were examined using regression analysis and a multiple logistic regression model adjusted for covariates.

RESULTS

The total of 3473 participants were analyzed in this study. Irregular cycle variability (>6 days) was significantly associated with high EPDS scores (adjusted: standardized beta = 0.049, p = 0.003) and with high cutoff EPDS scores (over 11) (adjusted OR = 1.40 [1.02-1.94], p = 0.038) but not with cycle length.

CONCLUSION

Irregular menstrual cycle before pregnancy was associated with depression during pregnancy. The health of the menstrual cycle during preconception needs to be further explored to promote healthy maternal mental health.

Association between Second-Time Mother's Prenatal Depression and Firstborn's Behaviour Problems: The Mediation Role of Parenting Daily Hassles

Background: With the relaxation of birth control policy in China in recent years, second-time mothers’ mental health has raised concerns. However, the impact of firstborn children’s behaviour problems on second-time mothers’ prenatal depression in families transitioning to siblinghood has received little attention from family psychologists. Aims: This research aims to investigate whether firstborn children’s behaviour problems affect second-time mothers’ prenatal depression and the mediation role of daily parenting hassles, i.e., minor stressors associated with parenting, on this relationship. Methods: Data about second-time mothers’ prenatal depression, parenting daily hassles, and firstborn children’s behaviour problems were collected from 105 families transitioning to two children families using mother-reported questionnaires. Regressions were used to analyze the data. Results: About half of the mothers in the sample have depressive symptoms. Firstborns’ behaviour problems did not have a direct effect on the mother’s prenatal depression, but the problems did have an indirect effect via parenting daily hassles. The mothers’ age was significantly associated with prenatal depression. Conclusions: The mediation role of parenting daily hassles in the association with firstborn’s behaviour problems and mother’s prenatal depression suggests the need for support that reduce the levels of daily parenting hassles from firstborn children.

Influencing factors of depressive symptoms during pregnancy in Beijing, China

Objective

Prenatal depression is a prevalent mental health challenge encountered during pregnancy and is notably associated with adverse maternal and neonatal outcomes. This study aimed to elucidate the likelihood and determinants of depressive symptoms among pregnant individuals in Beijing, thereby laying a foundational framework for the theoretical underpinning of prenatal screening and preemptive interventions for mental disorders.

Methods

The study dataset was derived from 4,564 pregnant individuals in Beijing utilizing a cross-sectional survey methodology. Data collection focused primarily on the personal and obstetric information of the participants. The Edinburgh Postnatal Depression Scale (EPDS) was employed as the primary screening tool to identify depressive symptoms.

Results

The prevalence of depressive symptoms among the included pregnant individuals was 4.1%. The univariate analysis results revealed statistically significant differences in the incidence of depressive symptoms in women with different parities, numbers of births, medication use, numbers of abortions, prepregnancy weights, and body mass indices (BMIs) (the χ2 values were 61.130, 52.008, 23.291, 5.293, and 12.681, respectively; P<0.05). There were statistically significant differences in the incidence of depressive symptoms among women with different occupation types (χ2 = 30.263, P<0.01). The multivariate logistic regression analysis results revealed that a greater number of pregnancies, number of births, and BMI were risk factors for prenatal depression, whereas the commercial and service worker occupation types were protective factors against prenatal depression.

Conclusion

Future directives should emphasize the enhancement of screening for depressive symptoms among pregnant individuals with greater parity and BMIs, alongside encouraging continued employment and flexible job selection. It is imperative to implement suitable intervention strategies for pregnant individuals exhibiting depressive symptoms to mitigate the incidence of adverse maternal and neonatal outcomes.

The Role of Maternal Depression Symptoms and Maternal Attachment in Predicting Exclusive Breastfeeding: A Multisite Prospective Study

Background: Previous research shows that 61% of children younger than 6 months in low- and middle-income countries (LMICs) are not exclusively breastfed. Although data on the role of pre- and postnatal depression on breastfeeding exclusivity is mixed, fetomaternal attachment might foster breastfeeding exclusivity. Thus, we tested the potential mediating role of fetomaternal attachment and postnatal depression in the relationship between maternal prenatal depression and exclusive breastfeeding. Materials and Methods: Data were collected as part of a prospective, cross-cultural project, Evidence for Better Lives Study, which enrolled 1208 expectant mothers, in their third trimester of pregnancy across eight sites, from LMICs. Of the whole sample, 1185 women (mean age = 28.32, standard deviation [SD] = 5.77) completed Computer-Aided Personal Interviews on prenatal depressive symptoms, fetomaternal attachment, and socioeconomic status. A total of 1054 women provided follow-up data at 3-6 months after birth, about postnatal depressive symptoms, exclusive breastfeeding, and infant health indicators. Path analysis was used to assess parallel mediation. Results: In the whole sample, the effect of prenatal depression on breastfeeding exclusivity was completely mediated by postnatal depression, whereas fetomaternal attachment did not mediate the relationship. The full mediation effect was replicated individually in Pakistan and Sri Lanka. Conclusions: The study results indicate that prenatal depression symptoms contributed to the development of depressive symptoms after birth, negatively affecting the probability of exclusive breastfeeding. Future research should explore this in early prevention interventions, increasing the chances of healthy child development in LMICs. Considering the mixed results around the sites, it is important to better understand the relationship between maternal depression, fetomaternal attachment and breastfeeding behavior in each site's socio-cultural context.

Maternal symptoms of prenatal depression predict context-incongruent negative emotion in infants

Prenatal symptoms of depression in mothers are associated with infants' emotional reactivity. Context-incongruent reactivity, comprising mismatches between the eliciting context and emotional reactions, predicts negative long-term socioemotional outcomes in children. However, the etiology of context-incongruent reactivity is largely unknown, obscuring a full understanding of its potential role as a vulnerability in models outlining the transmission of risk for emotion difficulties from mothers to offspring. We tested mothers' (N = 92) prenatal depressive symptoms as prospective predictors of infants' context-incongruent emotion. Greater prenatal symptoms predicted more context-incongruent negativity in infants even when controlling for context-congruent affect. Findings demonstrate a novel utility of context-incongruent emotion as one possible vulnerability linking mothers' prenatal depression to socioemotional difficulties in offspring.

Exploring prenatal depression and postpartum depression: Findings from a prospective cohort study at University Hospital Obstetrics in Damascus

The perinatal period is crucial for both mother and newborn, and mental health, including prenatal and postpartum depression (PPD), is a significant aspect. Screening for these disorders allows for early treatment and helps prevent risks to both mother and child. This prospective cohort study was carried out at University Hospital Obstetrics in Damascus City. The first phase was during the third trimester of pregnancy and the second phase involved a follow-up assessment after 6 weeks of delivery. The Arabic-validated version of the Edinburgh Postnatal Depression Scale questionnaire (EPDS) was used. A cutoff of 13 or higher was used to determine the presence of probable depression in both assessments. Of 347 pregnant women, 38.6% had prenatal depression (PND). 295 patients have achieved the second assessment, of which 30.2% had PPD. Furthermore, 42.6% who had PND developed PPD on follow-up. Binary logistic regression indicated that PND was predicted by non-Syrian nationality, paternal absence, poor financial status, number of previous pregnancies, and a history of depression independent of pregnancy. PPD was predicted by a history of PPD, and work status. Findings underscore potential value of early screening for depressive symptoms as a predictive measure. It is recommended that women with a history of depression receive heightened attention and care, irrespective of the timing of their depressive episodes.

A Mindfulness Application for Reducing Prenatal Stress

INTRODUCTION

Up to 40% of patients report depression or anxiety symptoms in pregnancy; feelings of increased stress are nearly universal. Antepartum stress is linked to adverse outcomes including preterm birth, low birthweight, postpartum depression, and maternal self harm. Unfortunately, limited treatment options exist, and patients are often hesitant to initiate medications prenatally. Thus, the development of efficacious nonpharmacologic interventions is crucial. This pilot study investigated the feasibility and impact of an application (app)-based mindfulness practice, begun in the first trimester, on maternal stress and pregnancy outcomes.

METHODS

The study enrolled patients prior to 15 weeks' gestation and followed them prospectively through birth. Patients were provided with a free subscription to Expectful, a commercially available prenatal mindfulness app, and asked to complete daily meditations. Patients completed the Perceived Stress Scale (PSS) self-assessment at 15 weeks and 28 weeks. PSS scores and pregnancy outcomes were compared with a historical control group of pregnant people who did not use the app.

RESULTS

Of 68 patients approached, 59 consented to enrollment. Of these, 21 used the app, with an average use of 170 minutes (range, 1.3-1315 min). The average PSS score was significantly lower in the app group at 28 weeks. Additionally, the change in PSS score for app users was greater compared with that of the historical control between enrollment and 28 weeks (-6.3 vs -0.95, P = .0008). Pregnancy outcomes were similar for app users and the historical control.

DISCUSSION

Our recruitment rate suggests pregnant patients are eager for a nonmedication intervention to decrease stress. However, adherence after enrollment was limited. For a subset of motivated patients, an app-based mindfulness practice significantly reduced perceived stress between the second and third trimesters compared with non-app users. Prenatal mindfulness apps represent an important low-intervention, low-cost, highly accessible tool for managing perinatal mood and stress.

The construction and validation of the novel nomograms for the risk prediction of prenatal depression: a cross-sectional study

Background

Nomograms are superior to traditional multivariate regression models in the competence of quantifying an individual's personalized risk of having a given condition. To date, no literature has been found to report a quantified risk prediction model for prenatal depression. Therefore, this study was conducted to investigate the prevalence and associated factors of prenatal depression. Moreover, two novel nomograms were constructed for the quantitative risk prediction.

Methods

In this cross-sectional study, the participants were recruited using convenience sampling and administered with the research questionnaires. The prevalence of prenatal depression was calculated with a cutoff point of ≥ 10 in the 8-item Patient Health Questionnaire. Univariate and multivariate binomial logistic regression models were subsequently employed to identify the associated factors of prenatal depression. Two nomograms for the risk prediction were constructed and multiple diagnostic parameters were used to examine their performances.

Results

The prevalence of prenatal depression was 9.5%. Multivariate binomial logistic regression model based on sociodemographic, health-related, and pregnancy-related variables (model I) suggested that unemployment, poor relationship with partners, antecedent history of gynecologic diseases, unplanned pregnancy, an earlier stage of pregnancy, and more severe vomiting symptoms were associated with increased risk of prenatal depression. In the regression model that further included psychosocial indicators (model II), unemployment, antecedent history of gynecologic diseases, unplanned pregnancy, an earlier stage of pregnancy, and a higher total score in the Pregnancy Stress Rating Scale were found to be associated with prenatal depression. The diagnostic parameters suggested that both nomograms for the risk prediction of prenatal depression have satisfactory discriminative and predictive efficiency and clinical utility. The nomogram based on model II tended to have superior performances and a broader estimating range and that based on model I could be advantageous in its ease of use.

Conclusions

The prevalence of prenatal depression was considerably high. Risk factors associated with prenatal depression included unemployment, poor relationship with partners, antecedent history of gynecologic diseases, unplanned pregnancy, an earlier stage of pregnancy, more severe vomiting symptoms, and prenatal stress. The risk prediction model I could be used for fasting screening, while model II could generate more precise risk estimations.
