The association between pre-pregnancy obesity and screening results of depression for all trimesters of pregnancy, postpartum and 1 year after birth: a cohort study

Association between oxidative balance score and risk of postpartum depression in Iranian women: a prospective cohort study

The oxidative balance score (OBS) serves as a comprehensive measure of exposures related to oxidative stress, considering both dietary antioxidants and lifestyle exposures. There is no evidence regarding the relation between OBS and postpartum depression (PPD). In this study, we aimed to determine the relationship between OBS during pregnancy and PPD. In this cohort study, 243 Iranian pregnant women were recruited using a convenience sampling method from 2022 to 2023. Dietary intakes were obtained using a validated food frequency questionnaire. OBS was separately constructed based on nutrients/lifestyle (NLOBS) and food groups/lifestyle (FLOBS) according to the previously proposed methods. PPD was diagnosed 4 to 6 weeks after delivery using the Edinburgh Postpartum Depression Scale. Cox proportional hazards regression was utilized to examine the relationship between OBS and PPD. Participants had a mean (SD) age of 30.9 ± 6.12 years. In total, 43 females were diagnosed with PPD. Findings revealed that, after controlling all confounders, subjects with the highest level of NLOBS, compared to the lowest, had a 69% lower risk of PPD (HR: 0.31; 95% CI: 0.12-0.83). Although a significant inverse relation was found between FLOBS and PPD in the crude model (HR: 0.43; 95% CI: 0.19-0.96); this association was not significant in fully adjusted model (HR: 0.53; 95% CI: 0.22-1.27). Considering subtypes of each score, inverse relations were significant for NOBS and LOBS, but not for FOBS. This study suggests that a higher OBS, particularly nutrient-based OBS, during pregnancy may be associated with a reduced risk of PPD. Further research is necessary to validate these findings.

Prevalence and Correlates of Depression Among Pregnant Women at King Abdulaziz Medical City: A Tertiary Hospital in Riyadh, Saudi Arabia

BACKGROUND

Women have a higher likelihood of experiencing depression during pregnancy due to the significant physiological and mental changes that occur during this critical period. The frequency of antenatal depression varies globally according to socioeconomic, healthcare, and cultural influences. The objective of this study is to investigate the prevalence of depression among pregnant women in Riyadh, Saudi Arabia.

MATERIALS AND METHODS

Women who were pregnant and who had undergone screening for depression were included in this cohort study that was conducted at King Abdulaziz Medical City (KAMC). Using a non-probability convenience sample technique, data was obtained from the hospital record system. Statistical significance was determined using Fisher's exact test and student's t-test, which analyzed demographic, clinical, demographic, and obstetric information. Significance was determined by a P-value that was lower than 0.05.

RESULTS

Among 367 people surveyed, the prevalence of depression was 2.5%. This is much lower than rates seen both globally and in Saudi Arabia. The majority were married and non-smokers with a high post-delivery BMI. A significant association was observed between depression and previous psychiatric diagnoses, while no significant relationships were found with gestational age, complications, chronic illnesses, or referral sources.

CONCLUSION

The research shows that the rate of perinatal depression among women in Riyadh is much lower than the average, highlighting the critical role of cultural factors and the need for validated, culturally sensitive screening tools. Recommendations for future research include longitudinal studies and the development of culturally tailored interventions to enhance the detection and management of depression during pregnancy, integrating mental health care into routine antenatal services.

The relationship between body mass index and perceived control over labor

BACKGROUND

Individuals with an increased body mass index (BMI) (≥ 30 kg/m2) experience higher rates of perinatal mental health disorders than individuals with BMI < 30. Personal experience of decreased control over labor has been associated with the development postpartum mood and anxiety disorders. However, no studies have investigated the association between BMI and experience of control over labor. This study aimed to assess perceived control over labor and compare patients with BMI ≥ 30 to those with BMI < 30.

METHODS

We performed a secondary analysis of a cross-sectional study of postpartum patients who delivered at term (37-41 weeks gestation). Postpartum, participants completed the Labour Agentry Scale (LAS), a validated tool to assess perceived control over labor/birth. Demographic, maternal health history and obstetric/neonatal outcomes were abstracted from the patient chart. Bivariate analyses were performed between those with BMI < 30 and those with BMI ≥ 30 using Fisher's exact test. Continuous LAS scores were compared between patients with BMI < 30 and BMI ≥ 30 using Wilcoxon rank-sum tests. Higher LAS scores indicate higher perceived control over labor. Multivariable linear regression was then performed to account for confounding factors identified a priori.

RESULTS

There was no difference in LAS between those with BMI ≥ 30 and BMI < 30. When stratified by World Health Organization (WHO) class of BMI, those with BMI ≥ 40 had a significantly lower LAS scores than those with BMI < 30 (147 vs. 163, p = 0.02), however, this finding was no longer significant after controlling for length of labor and cesarean birth.

CONCLUSION

Only participants with the highest BMI experienced decreased control over labor, and this finding was no longer significant after controlling for mode of delivery and length of labor. Further research into the experience of birthing people with BMI ≥ 30 is critical to understand the increased risk of perinatal mood disorders among this population.

Association between visceral adipose tissue and major depressive disorder across the lifespan: A scoping review

OBJECTIVES

Increasing evidence supports a bidirectional relationship between major depressive disorder (MDD) and obesity, but the role of visceral adipose tissue (VAT) as a measure of obesity in relation to MDD is not well understood. Here we review literature investigating the link between MDD and VAT in terms of biomarkers, sex differences, and aging.

METHODS

PubMed, EMBASE, PsycINFO, and CINAHL searches were conducted on December 11, 2020. No date or language limits were imposed. Major concepts searched were Depressive Disorder linked with Adipose Tissue, White, Hypothalmo-Hypophyseal System, and Pituitary-Adrenal System in addition to keywords. A final set of 32 items meeting criteria for inclusion.

RESULTS

Converging biological evidence suggests a significant bidirectional relationship between VAT and MDD across the lifespan. In adulthood, greater VAT was associated with increased risk for depression, especially in vulnerable groups such as individuals who are overweight/obese, postmenopausal women, and individuals with comorbid medical or psychiatric illness. In older adults, sarcopenia had an impact on the relationship between abnormal VAT and risk of depression. Additionally, sex differences emerged as a potential factor affecting the strength of the association between VAT and depression.

CONCLUSIONS

Elucidating the pathophysiological mechanisms associated with increased rates of depression in obese individuals will be crucial for developing specific treatment strategies that seek to improve outcomes in individuals with comorbid depression and obesity. Moreover, identifying age- and sex-specific risk factors may contribute to a more personalized medicine approach, thereby improving the quality of clinical care.

The impact of obesity-related neuroinflammation on postpartum depression: A narrative review

Obesity is currently one of the most serious health problems, affecting 13% of the world's adult population. Obesity is characterized by persistent low-grade chronic inflammation that assumes systemic proportions and triggers several associated metabolic diseases. Furthermore, obesity has been associated with an increased occurrence of central disorders such as impaired cognitive function, reward system dysfunction, and depression. In summary, there is a quantitative reduction in the release of neurotransmitters in depression. Postsynaptic cells capture lower concentrations of neurotransmitters, which leads to a functional reduction in the central nervous system (CNS). Globally, approximately 15-65% of women experience depressive symptoms during pregnancy, depending on their location. Depressive symptoms persist in some women, leading to postpartum depression (PPD). Thus, obesity may be considered a risk factor for PPD development. This study aimed to synthesize studies on the impact of obesity-related neuroinflammation and PPD. We conducted a narrative review of the relevant literature. The search was performed in electronic databases, specifically PubMed, selecting articles in English published from 2014 to 2021 using the narrative review methodology.

Pre-pregnancy BMI was associated with gestational depressive phenotypes in a population of 12,099 women in Chongqing, China

OBJECTIVE

To investigate the association between pre-pregnancy body mass index (BMI) and gestational depressive phenotypes.

METHODS

The pregnant women receiving the first prenatal examination (4th -13th week of gestation) in Chongqing Health Center for Women and Children were recruited between February 2020 and September 2021. Depressive phenotypes was assessed by the Patient Health Questionnaire (PHQ-9) and the Symptom Checklist 90 (SCL-90) scale at recruitment. Pre-pregnancy weight and height were self-reported by the participants. Demographic and obstetric characteristics were obtained from the hospital information system. The association between pre-pregnancy BMI and the scores of PHQ-9 or SCL-90 scale was investigated by uni-variate analysis with Kruskal-Wallis test and by multi-variate analysis with linear regression model with adjustment of age, parity, smoking, alcohol consumption, and assisted reproduction. The association between pre-pregnancy BMI and PHQ-9 or SCL-90 diagnosed depressive phenotypes was analyzed by Chi-square test and logistic regression respectively.

RESULTS

A total of 12,099 pregnant women were included, where 100% of them filled out the PHQ-9 scale and 99.6% filled out the SCL-90 scale, and 47.26% and 4.62% of the pregnant women had depressive phenotypes, respectively. Women with higher pre-pregnancy BMI had lower depressive phenotypes scores during pregnancy. Multivariable analysis of the PHQ-9 scale showed that overweight/obese subjects had a higher incidence of depressive phenotypes compared with subjects with normal BMI (OR=0.803, 95% CI [0.723, 0.892]). In a stratified analysis assessed by the PHQ-9, women who were overweight/obese prior to pregnancy were less likely to develop depressive phenotypes during pregnancy than women who were normal weight prior to pregnancy, regardless of whether they were nulliparous (OR=0.795, 95%CI[0.696,0.908]) or multiparous (OR=0.809, 95%CI[0.0.681,0.962]), while in the three age groups of 25-29 years, 30-34 years and ≥35 years, pre-pregnancy overweight/obesity were associated with lower risk of gestational depressive phenotypes. However, analysis of the SCL-90 scale showed no statistical association between depressive symptom and BMI. No substantial interaction was observed between BMI and parity or age.

CONCLUSIONS

Increased pre-pregnancy BMI may be associated with reduced risk of gestational depressive phenotypes in Chinese women. Independent studies are warranted to validate the findings of the present study.

Effect of Excessive Body Weight and Emotional Disorders on the Course of Pregnancy and Well-Being of a Newborn before and during COVID-19 Pandemic

This study aimed to evaluate whether excessive body weight and the COVID-19 pandemic affect depression, and subsequently whether depression, excessive body weight, and the COVID-19 pandemic affect the course of pregnancy, as well as the well-being of a newborn. The research material included data retrieved from the medical records of 280 pregnant women who were provided with care by medical facilities in Lublin (100 women with normal weight, 100 overweight women, 50 with Class I and 30 with Class II obesity). They completed a Beck depression inventory (BDI) in pregnancy twice, in order to assess the risk of occurrence of postpartum depression. Pre-pregnancy BMI positively correlated with the severity of depression, both at 10–13 weeks of pregnancy (p < 0.001), and at 32 weeks of pregnancy (p < 0.001). The higher the pre-pregnancy BMI, on average the higher the severity of depression. The severity of depression was significantly higher during the pandemic than before it in women with normal body weight before pregnancy (p < 0.001), as well as in those overweight (p < 0.001) and with Class II obesity (p = 0.015). Excessive body weight before pregnancy leads to depressive disorders during pregnancy, increases the risk of preterm delivery, and exerts a negative effect on the state of a newborn. Depressive symptoms among pregnant, overweight and obese women intensified during the COVID-19 pandemic.

Prevalence of Gestational Diabetes Mellitus in the Middle East and North Africa, 2000-2019: A Systematic Review, Meta-Analysis, and Meta-Regression

Women in the Middle East and North Africa (MENA) region are burdened with several risk factors related to gestational diabetes mellitus (GDM) including overweight and high parity. We systematically reviewed the literature and quantified the weighted prevalence of GDM in MENA at the regional, subregional, and national levels. Studies published from 2000 to 2019 reporting the prevalence of GDM in the MENA region were retrieved and were assessed for their eligibility. Overall and subgroup pooled prevalence of GDM was quantified by random-effects meta-analysis. Sources of heterogeneity were investigated by meta-regression. The risk of bias (RoB) was assessed by the National Heart, Lung, and Blood Institute's tool. One hundred and two research articles with 279,202 tested pregnant women for GDM from 16 MENA countries were included. Most of the research reports sourced from Iran (36.3%) and Saudi Arabia (21.6%), with an overall low RoB. In the 16 countries, the pooled prevalence of GDM was 13.0% (95% confidence interval [CI], 11.5-14.6%, I² , 99.3%). Nationally, GDM was highest in Qatar (20.7%, 95% CI, 15.2-26.7% I² , 99.0%), whereas subregionally, GDM was highest in Gulf Cooperation Council (GCC) countries (14.7%, 95% CI, 13.0-16.5%, I² , 99.0%). The prevalence of GDM was high in pregnant women aged ≥30 years (21.9%, 95% CI, 18.5-25.5%, I² , 97.1%), in their third trimester (20.0%, 95% CI, 13.1-27.9%, I² , 98.8%), and who were obese (17.2%, 95% CI, 12.8-22.0%, I² , 93.8%). The prevalence of GDM was 10.6% (95% CI, 8.1-13.4%, I² , 98.9%) in studies conducted before 2009, whereas it was 14.0% (95% CI, 12.1-16.0%, I² , 99.3%) in studies conducted in or after 2010. Pregnant women in the MENA region are burdened with a substantial prevalence of GDM, particularly in GCC and North African countries. Findings have implications for maternal health in the MENA region and call for advocacy to unify GDM diagnostic criteria.

Does Perceived Quality of Care Moderate Postpartum Depression? A Secondary Analysis of a Two-Stage Survey

OBJECTIVE

The purpose of this study was to examine if women's perceptions of the quality of hospital care during childbirth moderate their risks for symptoms of postpartum depression (PPD).

METHODS

This cross-sectional secondary analysis analyzed data from the Listening to Mothers III (2013) series surveys with a weighted sample size of 1057 of women surveyed from across the United States. PPD symptoms were defined according the Patient Health Questionnaire-2. Associations between risk factors and PPD symptoms were tested using logistic regressions with the moderating variable of perceived quality of care then added to models with significant risk factors.

RESULTS

Of the 22 potential risk factors for PPD symptoms, 10 were found to be significantly associated with PPD symptoms in this sample of women. Very good perceived quality of care moderated the following risk factors for PPD symptoms in a protective direction: relationship status (p = 0.01), pre-pregnancy BMI (p = 0.02), and pain that interfered with routine activities 2 months postpartum (p = 0.003).

CONCLUSIONS

These findings suggest risk factors for PPD symptoms are moderated by perceived quality of care and therefore, maternity providers can influence women's psychological wellbeing postpartum by providing very good perceived quality of care during the hospital stay for birth. However, these findings should be interpreted cautiously due to a lack of a direct, proven relationship between provider action and women's perceived quality of care.

Pre-natal and post-natal anxiety in relation to pre-pregnancy obesity: A cohort study on Iranian pregnant women

Background:

To determine the association between pre-conception obesity and screening results of pre-natal and post-natal anxiety in women that referred to the health centers of Tabriz, Iran.

Methods:

62 obese (class 2-3) and 245 normal-weight women were enrolled in the first trimester of pregnancy through the cohort study and followed-up 1 year after childbirth from December 2012 to January 2016. The Beck anxiety inventory scale (BAI-II) was completed in five time points: the first, second, third trimester of pregnancy, 6–8 weeks and 12 months after childbirth. Chi-square, Fisher’s exact tests, Independent t-test, Mann-Whitney, and multivariate logistic regression adjusted for confounders were used for data analysis. Statistically significant was considered as p<0.05.

Results:

The rate of moderate to severe anxiety in 1^st, 2^nd, 3^rd trimesters of gestation, 6–8 weeks and 12 months after birth was 8.6%, 10%, 12.6%, 7.8%, 6.5% in normal weight women versus 18%, 17.9%, 19.2%, 12.5%, 19.4% in obese class II women, respectively. The odds of anxiety in the first trimester of pregnancy for class 2–3 obesity was 2.72-fold greater than normal weight group [adjusted odds ratio (aOR) 2.72, 95% confidence interval (CI) 1.14–6.47; p=0.023]. This odd was 3.30- fold (aOR 3.30, 95%CI 1.13-9.60; p=0.045) for 1 year after birth.

Conclusion:

Obesity remained associated with positive screening for anxiety in the first trimester of pregnancy and one year after birth. Obese women more likely require special medical care during their pregnancy due to its impacts on mood.

Postpartum Perceived Stress Explains the Association between Perceived Social Support and Depressive Symptoms

BACKGROUND

Limited research has focused on longitudinal interrelations between perceived social support, perceived stress, and depressive symptoms beyond the first postpartum months. This study tested an alternative primary hypothesis within the stress process model examining whether perceived stress mediated the association between perceived social support and depressive symptoms from 1 to 24 months postpartum. Secondary purposes examined whether these factors 1) changed from 1 to 24 months postpartum and 2) predicted depressive symptoms.

METHODS

Women (N = 1,316) in a longitudinal cohort study completed validated measures of perceived social support, perceived stress, and depressive symptoms at 1, 6, 12, 18, and 24 months postpartum via telephone interviews. Analyses examined changes in psychosocial factors (repeated measures analysis of variance) and the extent to which perceived social support and perceived stress predicted depressive symptoms and supported mediation (linear regression).

RESULTS

Perceived social support decreased, perceived stress increased, and depressive symptoms remained constant from 1 to 18 months, then increased at 24 months. Low perceived social support predicted 6-month depressive symptoms, whereas perceived stress predicted depressive symptoms at all time points. Perceived stress mediated the association between perceived social support and depressive symptoms across 24 months such that low perceived social support predicted perceived stress, which in turn predicted depressive symptoms.

CONCLUSIONS

Intervention scientists may want to focus on strengthening perceived social support as a means to manage perceived stress in an effort to prevent a long-term trajectory of depression.

Trends in obesity and impact on obstetric outcomes in a regional hospital in Victoria, Australia

AIMS

Obesity-related complications have been identified across the entire childbearing journey. This study investigated changes in obesity prevalence and their impact on obstetric outcomes in a regional hospital in Victoria, Australia.

METHODS

All women delivering during 1 January 2010 and 31 December 2016 were eligible to participate. Trends over time and outcomes were assessed on body mass indices (BMI). Incidences of complications were compared by BMI categories. The effect of obesity on hospital length of stay (LoS) was further assessed using the Generalised Estimating Equations approach.

RESULTS

During the study period a total of 6661 women of whom 27.5% were overweight, and 16.1, 7.7, and 5.5% were respectively obese class I, class II, and class III, contributed to 8838 births. An increased trend over time in the prevalence of obesity (BMI > 35.0) (P = 0.041) and a decreased trend for vaginal deliveries for the whole sample (P = 0.003) were found. Multiple adverse outcomes were associated with increasing maternal BMI including increased risk of gestational diabetes, gestational hypertension, preeclampsia, emergency caesarean section, shoulder dystocia, macrosomia, and admission to special care. The multivariable analysis showed no associations between LoS and BMI.

CONCLUSIONS

Over a short period of seven years, this study provides evidence of a significant trend toward more obesity and fewer vaginal births in a non-urban childbearing population, with increasing trends of poorer health outcomes. Assessing needs and risk factors tailored to this population is crucial to ensuring a model of care that safeguards a sustainable and effective regional maternity health service.

The association between body mass index and postpartum depression: A population-based study

BACKGROUND

Postpartum depression (PPD) reportedly affects between 6.5-19% of all new mothers. Identifying those at greatest risk for PPD has implications for prevention, early detection and intervention. While the relationship between extremes of body mass index (BMI) and depression has been frequently studied, the association between BMI and PPD is less understood.

METHODS

Prospective cohort of all women with live singleton births in Sweden 1997-2008. We calculated the relative risk (RR) for PPD in relation to each woman's BMI and depression history. PPD diagnosis was based on a clinical diagnosis of depression within the first postpartum year.

RESULTS

First trimester BMI measurements were available for 611,506 women. Low BMI (< 18.5) RR_adj = 1.52, [95% CI: 1.30-1.78] and high BMI (> 35) RR_adj = 1.23, [95% CI: 1.04-1.45] were associated with increased PPD risk. Women with a depression history had an increased risk with low BMI (RR_adj = 1.51, [95% CI: 1.17-1.95]).

LIMITATIONS

Only first births were analyzed, potentially underestimating PPD incidence. Clinical data from health registries offers limited resolution regarding the specificity of diagnoses and incomplete sensitivity if women do not seek care.

CONCLUSIONS

First trimester of pregnancy BMI is associated with PPD risk. This risk is further modified by depression history. While low BMI places all women at risk for PPD, being overweight increases risk of PPD only in women without a history of depression. Future research should explore potentially modifiable mechanisms involved in the relationship between PPD and BMI and should also examine interventional strategies for pregnant women at the extremes of BMI and/or with a depression history.

Association Between Antenatal and Postpartum Depression and Anxiety with Weight Retention 1 Year After Childbirth: A Longitudinal Study

This was an observational, longitudinal study investigated the association between anxiety and depression in trimesters of pregnancy and early postpartum with weight retention 1 year after childbirth. Sixty-two pregnant women aged 18-35 years with a BMI of 35 or higher and 245 pregnant women with normal BMI (BMI 18.5-24.9 kg/m²) were recruited at their initial prenatal visit in the health centers. The Edinburgh Postnatal Depression Scale (EPDS) and Beck Anxiety Inventory (BAI-II) were completed in five time points, the first, second, third trimester of pregnancy, 6-8 weeks and 12 months after delivery. Pre-pregnancy weight and weight retention at 1 year postpartum was measured. A significant relationship was found between first trimester (adjusted mean difference: aMD 3.416; 95% CI 1.392-5.441) and postpartum (aMD 3.042; 95% CI 0.538-5.547) depression as well as first trimester's anxiety (aMD 3.050; 95% CI 0.631-5.470) with weight retention at 1 year after childbirth.

The Relationship between Gestational Weight Gain and Postpartum Depression in Normal and Overweight Pregnant Women

Objective

To investigate the relationship between weight gain in pregnancy and postpartum depression (PPD) in normal and overweight pregnant women.

Methods

The participants of this prospective cohort study were 223 healthy pregnant women with the first trimester body mass index (BMI) between 18.5 and 30 and the gestational age of 10-14 weeks and depressed women were excluded with Beck questionnaire in the first trimester. The evaluation included weight gain at the end of the second and third trimesters and the screening of PPD in 6-8 weeks after delivery by Edinburgh scale.

Results

49 participants were excluded from the study and data from 174 people were analyzed. 32.2% of mothers were scored above 12 in the Edinburgh scale. The only variable associated with depression was the third trimester weight gain (OR 1.17, 95%CI 1.04-1.32).

Conclusion

In addition to considering other risk factors for postpartum depression, health care providers should consider the higher probability of PPD in prepregnancy normal and overweight women who have excessive weight gain especially in the third trimester of pregnancy.

Antenatal and postnatal depression in women with obesity: a systematic review

Obesity and depression are prevalent complications during pregnancy and associated with severe health risks for the mother and the child. The co-occurrence of both conditions may lead to a particular high-risk group. This review provides a systematic overview of the association between pre-pregnancy obesity and antenatal or postnatal depression. We conducted a systematic electronic literature search for English language articles published between January 1990 and March 2017. Inclusion criteria were (a) adult pregnant women, (b) women with pre-pregnancy obesity and normal weight controls, (c) definition of obesity according to the IOM 1990/2009 criteria, (d) established depression measure, and (e) report on the association between pre-pregnancy obesity and antenatal or postnatal depression. Fourteen (eight prospective (PS), six cross-sectional (CS)) studies were included. One study reported data from a large community-based sample, and one reported cross-national data. Of 13 studies examining pre-pregnancy obesity and antenatal depression, 9 found a higher risk or higher levels of antenatal depression among women with obesity relative to normal weight (6 PS, 3 CS), while 4 studies found no association (2 PS, 2 CS). Of four studies examining pre-pregnancy obesity and postnatal depression, two studies found a positive association (two PS), one study (CS) reported different findings for different obesity classes, and one study found none (PS). The findings suggest that women with obesity are especially vulnerable to antenatal depression. There is a need to develop appropriate screening routines and targeted interventions to mitigate negative health consequences for the mother and the child. Research addressing the association between obesity and postnatal depression is too limited to draw solid conclusions. Results are mainly based on selective samples, and there is a need for further high-quality prospective studies examining the association between pre-pregnancy obesity and antenatal and postnatal depression.
