Association between dietary patterns during the third trimester and the risk of postpartum depression in China

Influencing factors for postpartum depression in women with gestational diabetes mellitus

Objective

It remains undefined about the association between gestational diabetes mellitus (GDM) and postpartum depression (PPD). Hence, a cross-sectional study was conducted to evaluate the association between GDM and PPD among pregnant women and to investigate the influencing factors for PPD.

Methods

From June 2021 to June 2022, 205 parturients with GDM and 201 without GDM were included in the study as the GDM group and the control group, respectively. The collected data from the general information questionnaire and Self Rating Depression Scale (SDS) were statistically analyzed based on binomial logistic regression analyses and generalized linear mixed models (GLMMs).

Results

Age at delivery, gestational age, glycosylated hemoglobin, triglyceride, SDS, and proportions of women who had a history of induced abortion or GDM were significantly different between the GDM group and control group (P<0.05). The incidence of PPD in the GDM group was significantly higher than that in the control group. The neonatal body weight and triglyceride in GDM women with PPD were significantly lower than those in GDM women without PPD (P<0.001). The univariate logistic regression analysis demonstrated that educational age was a protective factor, while glycosylated hemoglobin and GDM were risk factors for PPD. The multiple linear regression analysis revealed that neonatal body weight (OR=-0.904, 95%CI: -1.657 to -0.152, P=0.019) and educational age (OR=-0.166, 95%CI: -0.306 to -0.025, P=0.021) were protective factor, while GDM (OR=1.854, 95%CI: 1.027-2.681, P<0.0001) was a risk factor for PPD.

Conclusion

GDM may be associated with PPD. Neonatal body weight and educational age were protective factors for PPD, and GDM was a risk factor for PPD. Therefore, more attention should be paid to the mental health status of women with GDM, especially those with lesser educational age and lower neonatal body weight.

Maternal Fiber Intake and Perinatal Depression and Anxiety

(1) Background: Dietary fiber can significantly alter gut microbiota composition. The role of the gut microbiome in the Gut-Brain Axis and modulation of neuropsychiatric disease is increasingly recognized. The role of antenatal diet, particularly fiber intake, in mitigating maternal mental health disorders remains unexplored. The objective of this review is to investigate the association between maternal fiber intake and perinatal depression and anxiety (PDA). (2) Methods: A literature review of PubMed and Google Scholar was conducted using appropriate keyword/MeSH terms for pregnancy, diet, fiber, and mental health. Observational and clinical trials published between 2015 and 2021 were included and data pertaining to dietary patterns (DP), food intake, mental health, and demographic data were extracted. The top three fiber-containing food groups (FG) per study were identified using a sum rank scoring system of fiber per 100 g and fiber per serving size. The consumption of these top three fiber FGs was then ranked for each dietary pattern/group. Mental health outcomes for each study were simplified into three categories of improved, no change, and worsened. The relationship between top three fiber FGs consumed within each DP and mental health outcomes was analyzed using Spearman's correlation. (3) Results: Thirteen of fifty-two studies met the inclusion criteria. Ten (76.9%) studies assessed DPs (seven examined depression only, two examined depression and anxiety, and one examined anxiety only). Seven (53.9%) studies reported at least one significant positive relationship between mental health outcomes and DPs while three reported at least one negative outcome. Three (23.1%) studies compared intake of different food groups between depressed and non-depressed groups. In studies of DPs, the average consumption ranking of the top three fiber FGs bore a significant inverse association with mental health outcomes [r = -0.419 (95%CI: -0.672--0.078)] p = 0.015. In studies comparing the intake of different FGs between depressed and non-depressed groups, the consumption of top-ranking fiber foods was higher in the non-depressed groups, but significantly higher in four of the ten high fiber FGs. (4) Conclusions: This study reframes findings from previously published studies of maternal diet and mental health outcomes to focus on fiber intake specifically, using a fiber ranking system. A significant correlation between lower intake of fiber and poorer mental health outcomes warrants further investigation in future studies.

Perinatal dietary patterns and symptomatic depression: A prospective cohort study

To promote maternal and infant health, there is a need to optimise the dietary pattern of pregnant women to reduce perinatal depression. This prospective cohort study was conducted from June 2020 to February 2022, 300 women from a medical center were interviewed during late pregnancy and at 4-6 weeks postpartum. Dietary patterns were derived by factor analysis using a semiquantitative food frequency questionnaire. Symptomatic depression was defined using the Edinburgh Postpartum Depression Scale (EPDS, ranged 0-30). Their dairy, vegetable and fruit intakes were below the Taiwanese recommendations for pregnant women. Symptomatic depression (EPDS ≥10) affected 31.3% in the third trimester and 35.7% postpartum. Pre- and post-EPDS scores were positively correlated (r = 0.386, p < 0.001). Approximately 55% of those depressed before delivery were also depressed postpartum. For late pregnancy, four dietary patterns were identified ('Good oil', 'Vegetables and fruits', 'Omnivorous' and 'Refined-grain and organ meats'). Dietary patterns were classified according to quartiles (Q). Higher omnivorous pattern scores reduced the risk of depression. For prenatal depression, with Q1 as a reference, the risk was reduced by 38% for Q2, 43% for Q3 and 59% for Q4 (p for trend = 0.068). These findings became evident postpartum (reduced risk by 68% for Q2, 69% for Q3 and 70% for Q4 (p = 0.031; p for trend = 0.0032). The association between dietary patterns and depression encourages the routine nutritional management of pregnant women.

Maternal Dietary Patterns and Risk of Postpartum Depression: A Systematic Review

OBJECTIVE

Postpartum depression (PPD) has deleterious effects on both maternal and child outcomes. Poor maternal nutrition during pregnancy has been implicated in the development of PPD. This review aimed to explore the association between the overall dietary intake patterns during pregnancy and the development of PPD.

METHODS

A literature search was performed in PubMed, Embase, Scopus, CINAHL, and PsycINFO databases for relevant randomized controlled trials, cohort and cross-sectional studies published up to 17th September 2020. Included studies assessed at least one dietary pattern during pregnancy and reported on PPD. The Newcastle Ottawa Scale and the Joanna Briggs Institute critical appraisal tools were used to assess the quality of methodology. A narrative analysis was conducted.

RESULTS

Ten studies (eight cohort and two cross-sectional) were included with substantial heterogeneity in measurements of dietary intake exposures and PPD. The studies identified several types of healthy dietary patterns, including a 'healthy', 'health conscious', 'Japanese', 'high-glycemic index/glycemic load', 'Vegetable', 'Nut-Fruit', 'Seafood', and 'compliance with the Australian Dietary Guidelines'. The 'Western', 'unhealthy', 'Beverage', 'Cereal-Meat', and 'Egg' were labelled as unhealthy dietary patterns. Four of the eight studies showed an inverse association between adherence to healthy diets and risk of PPD, whereas only one of the seven studies showed that adherence to unhealthy diets was associated with increased risk of PPD. Methodological quality of the studies varied across the sample.

CONCLUSIONS

Our findings indicate that adherence to a healthy diet may be beneficial for PPD. However, the relationship between unhealthy diets and PPD needs to be corroborated by more high-quality studies.

Maternal n-3 PUFA Intake During Pregnancy and Perinatal Mental Health Problems: A Systematic Review of Recent Evidence

PURPOSE OF REVIEW

Pregnant women are vulnerable to mental health problems. Increasing evidence shows that omega-3 polyunsaturated fatty acid (n-3 PUFA) intake during pregnancy is beneficial to maternal perinatal mental health. A systematic review is needed to examine the associations reported in recent studies. The objective of this review was to provide an updated review on the association of antenatal n-3 PUFA intake via different sources (seafood, fish, overall diet, and supplementation) with perinatal mental health problems including depression, anxiety, and psychological distress.

RECENT FINDINGS

Searches were performed in Web of Science, Embase, PubMed, and APA PsycInfo databases on 21 June 2021. A total of 2133 records were screened. Data including the name of the first author, publication year, study design, sample characteristics, dietary assessment time and tools, mental health outcome measures, and other relevant information were extracted. In total, 13 articles were included in this review and assessed qualitatively. The results demonstrated that dietary intake of n-3 PUFA during pregnancy was associated with perinatal mental health, but the effect of n-3 PUFA supplementation was influenced by pre-existing medical conditions, socio-demographic characteristics, and dietary and lifestyle patterns during pregnancy. Our review found that sources of n-3 PUFA may have differential effects on woman's mental health during and after pregnancy. Further research using large-size cohort or well-controlled trial protocol is needed to determine the effect of n-3 PUFA supplementation during pregnancy on perinatal mental health.

Exercise, Mediterranean Diet Adherence or Both during Pregnancy to Prevent Postpartum Depression-GESTAFIT Trial Secondary Analyses

Targeting lifestyle behaviors during pregnancy is crucial to prevent the highly prevalent postpartum depression and its consequences. In these secondary analyses of an intervention trial to investigate the effects of concurrent exercise training on postpartum depression, we aimed to investigate the potential role of Mediterranean diet (MD) adherence on the exercise effects. A total of 85 pregnant women met the per-protocol criteria (exercise n = 46, control n = 39). The exercise program was delivered in 60 min sessions, 3 days/week, from the 17th gestational week until birth. Women's dietary habits were assessed with a food frequency questionnaire. The Mediterranean Food Pattern (an MD index) was derived from it to assess MD adherence. We used the Edinburgh Postnatal Depression Scale to assess postpartum depression. The postpartum depression score was not statistically different between control and exercise groups (p > 0.05). A higher consumption of fruits (β = -0.242, p = 0.022), lower intake of red meat and subproducts (β = 0.244, p = 0.020), and a greater MD adherence (β = -0.236, p = 0.027) were associated with lower levels of postpartum depression. Greater adherence to the MD during pregnancy was associated with fewer depressive symptoms and a lower risk of postpartum depression. Postnatal depression was not reduced by prenatal exercise. Promoting fruit consumption while controlling the intake of red meat during pregnancy might prevent postnatal depression.

Association between Dietary Patterns and the Risk of Depressive Symptoms in the Older Adults in Rural China

Geriatric depression, a chronic condition, has become a substantial burden in rural China. This study aimed to assess the association between dietary patterns and the risk of geriatric depression in rural China. Between March 2018 and June 2019, 3304 participants were recruited for this cross-sectional study in rural Tianjin, China. Principal component analysis was used to determine the major dietary patterns. The associations between dietary patterns and the risk of geriatric depression were assessed using a logistic regression model. Four dietary patterns were identified: vegetables-fruit, animal food, processed food, and milk-egg. The study found that vegetable-fruit (Q2 vs. Q1: OR = 0.62, 95% CI: 0.46–0.83; Q3 vs. Q1: OR = 0.54, 95% CI: 0.38–0.75; Q4 vs. Q1: OR = 0.39, 95% CI: 0.26–0.57) and animal food patterns (Q3 vs. Q1: OR = 0.69, 95% CI: 0.50–0.95; Q4 vs. Q1: OR = 0.58, 95% CI: 0.41–0.82) were associated with a decreased risk of depression, and inflammatory dietary pattern (Q2 vs. Q1: OR = 1.71, 95% CI: 1.23–2.38; Q3 vs. Q1: OR = 1.70, 95% CI: 1.22–2.36; Q4 vs. Q1: OR = 1.44, 95% CI: 1.03–2.03) was associated with an increased risk of depression. The present findings reinforce the importance of adopting an adequate diet consisting of vegetables, fruit and animal foods, while limiting the intake of pro-inflammatory foods, to decrease the risk of depression.

Towards Universal Screening for Postpartum Depression in China: Lessons Learned from a Comprehensive Prevention Programme in Shenzhen

PURPOSE

This study was conducted to assess the real-world efficacy of a universal programme for the prevention of postpartum depression (PPD) in Shenzhen. Given the lack of evidence on routine PPD screening and intervention in China, it sought to provide insights for programme planning and implementation, particularly in relation to achievement of the targets set by the first national guidelines for PPD prevention and treatment.

METHODS

Using routine health information system data, the PPD screening, referral and intervention rates for 2015-2019 were calculated and compared to the programmes targets. Trends of variables were tested by using trend χ².

RESULTS

The programme screened 137,761 to 178,857 women for PPD every year with the coverage among all postpartum women increased steadily from 71.1% to 82. 5% (χ² = 10145.251, p < 0.001). The PPD-positive rate maintained between 4.06% and 4.89%. However, although referral messages were given to an increased percentage of PPD-positive women (χ² = 1090.908, p < 0.001), the intervention rate (i.e., referral uptake) were far lower than the programme target of 80%.

CONCLUSIONS

This study demonstrated high efficacy of Shenzhen's comprehensive PPD prevention programme initiated in 2013. The resultant rise in the screening rate among all postpartum women, together with a high referral rate of those screened positive, have contributed to the city's relatively low PPD prevalence. PPD screening and intervention should be included as part of basic public health services to ensure universal coverage and specific strategies should be adopted to ensure referral uptake.

Mode of Delivery Is Associated with Postpartum Depression: Do Women with and without Depression History Exhibit a Difference?

Whether the mode of birth delivery correlates with the incidence of postpartum depression (PPD) is still under debate. This study seeks to clarify such a correlation and to further investigate if there are any differences in the likelihood of PPD medical care use among women with and without a history of depression. A logistic regression at two assessment points (6-month and 12-month postpartum) on the National Health Insurance Database in Taiwan is performed. In total, 32,729 women were included who gave first birth from 2007 to 2011 via cesarean section (CS), elective CS, and vaginal delivery, of whom 3580 (10.9%) were diagnosed with a history of depression. Findings show that CS was associated with a higher likelihood of PPD doctor visits regardless of whether the women have a history of depression or not, but elective CS tended to have different impacts for these two groups of women. Mentally healthy women who experienced elective CS had 1.36- and 1.64-times higher risk of PDD medical care use than those who delivered vaginally, whereas previous depressive women undertaking an elective cesarean birth had no significant difference observed in incidences. A notably higher risk of elective CS delivery versus vaginal delivery for mentally healthy women suggests that elective CS is not clinically appropriate, yet it might be an alternative to vaginal delivery with careful counseling for pregnant women who experience a history of depression.

Additional evidence on prevalence and predictors of postpartum depression in China: A study of 300,000 puerperal women covered by a community-based routine screening programme

BACKGROUND

Previous studies on the prevalence and predictors of postpartum depression (PPD) in China were mostly hospital-based with relatively small study samples. Basing on a routine screening programme, this study assessed the prevalence and factors associated with PPD at community level.

METHODS

A cross-sectional study was conducted with all the women who delivered in a hospital and were screened for depression during routine postpartum home visits in Shenzhen between 2015 August and 2017 April. The Edinburgh Postnatal Depression Scale was used as the screening tool with a cut-off score of 10. Predictors of PPD were determined by Chi-square test and stepwise logistic regression.

RESULTS

Approximately 300,000 puerperal women were included in the study with a PPD prevalence of 4.3%. Prenatal anxiety and depression were associated with 4.55 and 3.80 times of PPD risk, respectively. Stressful life events, family history of mental illness, poor economic status, low Apgar scores and birth defects of the infants, bottle and mixed feeding, as well as living with parents-in-low after childbirth were related to moderate risk. Higher gravidity and parity, larger gestation age, prenatal education, and living with the women's own parents were associated with lower risk.

LIMITATIONS

The large sample size might have suggested statistically significant differences which were not practical.

CONCLUSIONS

The prevalence of PPD at community level is significantly lower than the rates detected within hospitals. Prenatal anxiety and depression are the most important predictors of PPD. Integrating depression screening into routine postpartum home visits facilitates achievement of universal coverage.

Gender-specific prevalence and influencing factors of depression in elderly in rural China: A cross-sectional study

BACKGROUND

With an aging population, late-life depression has been a major health problem in rural China. This study aims to explore the gender-specific prevalence of geriatric depression in rural Tianjin, its influencing factors, and to provide a scientific basis for the prevention and intervention of depression in the elderly.

METHODS

A cross-sectional study of 4,933 elderly individuals in rural Tianjin was conducted using the cluster sampling method. The independent samples t-test and chi-squared test were used to assess differences in participants' characteristics by depressive symptoms, while multiple linear regressions and multiple logistic regressions were used to analyze the potential influencing factors of depression.

RESULTS

The prevalence of geriatric depression was found to be 12.2% in the study participants (9.5% in men and 14.5% in women). Gender, education, household income, employment, living alone, social activities, physical exercise and chronic diseases were associated with depression (P<0.05). In addition to the above factors, sleep duration was also related with scores on self-rating depression scale (P<0.05).

LIMITATIONS

The study used a cross-sectional approach, so causation cannot be concluded.

CONCLUSIONS

Late-life depression is a serious mental health issue in rural China, highlighting the importance of appropriate diagnosis and treatment as a priority to improve the quality of mental health.

Effects of Folic Acid Combined with DHA Supplementation on Cognitive Function and Amyloid-β-Related Biomarkers in Older Adults with Mild Cognitive Impairment by a Randomized, Double Blind, Placebo-Controlled Trial

BACKGROUND

The neuroprotective benefits of combined folic acid and docosahexaenoic acid (DHA) on cognitive function in mild cognitive impairment (MCI) patients are suggested but unconfirmed.

OBJECTIVE

To explore the effects of 6-month folic acid + DHA on cognitive function in patients with MCI.

METHODS

Our randomized controlled trial (trial number ChiCTR-IOR-16008351) was conducted in Tianjin, China. We divided 160 MCI patients aged > 60 years into four regimen groups randomly: folic acid (0.8 mg/day) + DHA (800 mg/day), folic acid (0.8 mg/day), DHA (800 mg/day), and placebo, for 6 months. Cognitive function and blood amyloid-β peptide (Aβ) biomarker levels were measured at baseline and 6 months. Cognitive function was also measured at 12 months.

RESULTS

A total of 138 patients completed this trial. Folic acid improved the full-scale intelligence quotient (FSIQ), arithmetic, and picture complement scores; DHA improved the FSIQ, information, arithmetic, and digit span scores; folic acid + DHA improved the arithmetic (difference 1.67, 95% CI 1.02 to 2.31) and digital span (1.33, 0.24 to 2.43) scores compared to placebo. At 12 months, all scores declined in the intervention groups. Folic acid and folic acid + DHA increased blood folate (folic acid + DHA: 7.70, 3.81 to 11.59) and S-adenosylmethionine (23.93, 1.86 to 46.00) levels and reduced homocysteine levels (-6.51, -10.57 to -2.45) compared to placebo. DHA lower the Aβ40 levels (-40.57, -79.79 to -1.35) compared to placebo (p < 0.05), and folic acid + DHA reduced the Aβ42 (-95.59, -150.76 to -40.43) and Aβ40 levels (-45.75, -84.67 to -6.84) more than DHA (p < 0.05).

CONCLUSION

Folic acid and DHA improve cognitive function and reduce blood Aβ production in MCI patients. Combination therapy may be more beneficial in reducing blood Aβ-related biomarkers.
