הקשר בין הצלחת לבין מצב של דיכאון וחרדה במהלך ואחרי הלידה
כולם יודעים שהתזונה משפיעה על המצב הגופני, אך האם ידעתן שיש לה נגיעה גם למצב הרוח שלכן וגם לחיי הילד שתלדו?
הקשר בין דיכאון ורמת חרדה גבוהה לבין השפעות שליליות על העובר ועל ההריון עצמו מבוסס היטב מבחינה מחקרית: למתח ולחרדה יש ביטויים גופניים שמשפיעים על האם ועל התינוק במידה שלא כומתה עדיין. עם זאת ברור שככל שהדיכאון משמעותי יותר ונובע ממצבי דחק משמעותיים יותר, כך יש יותר סיכוי להשפעה על העובר. לכתבה המלאה – הקשר בין הצלחת לבין מצב של דיכאון וחרדה במהלך ואחרי הלידהאומגה 3 ודיכאון – ספרות מחקר

The purpose of the present study was to investigate for a possible relationship between depression and serum adiponectin and adipose tissue omega-3 and omega-6 PUFA. The sample consisted of 90 healthy adolescent volunteers from the island of Crete. There were 54 girls and 36 boys, aged 13 to 18. The mean age was 15.2 years. Subjects were examined by the Preventive Medicine and Nutrition Clinic of the University of Crete.
Depression was assessed through the use of the Beck Depression Inventory (BDI) and the Center for Epidemiologic Studies Depression Scale (CES-D). Fatty acids were determined by gas chromatography in adipose tissue. CES-D correlated with dihomo-gamma linolenic acid (DGLA (Multiple linear regression analyses showed that BDI was negatively associated with eicosapentaenoic acid (EPA), while CES-D was positively associated with DGLA in adipose tissue. Serum adiponectin was not significantly associated with depression. The negative relationship between adipose EPA and depression in adolescents, is in line with findings of previous studies involving adult and elderly subjects, demonstrating
negative relations between depression and adipose omega-3 PUFA. This is the first literature report of a relationship between depression and an individual omega-3 fatty acid in adolescents. The inverse relationship between adipose EPA and depression indicates that a low long-term dietary intake of EPA is associated with an increased risk for depression in adolescents.

Depression and long chain n-3 fatty acids in adipose tissue in adults from Crete
G Mamalakis1, N Kalogeropoulos2, N Andrikopoulos2, C Hatzis1, D Kromhout3, J Moschandreas1 and A Kafatos1 1Department of Social Medicine Preventive Medicine and Nutrition, School of Medicine, University of Crete, Iraklion, Crete, Greece; 2Laboratory of Food Chemistry-Biochemistry-Physical Chemistry, Department of Science of Dietetics-Nutrition, Harokopio University, Kallithea, Athens, Greece and 3National Institute for Public Health and the Environment, Nutrition and Consumer Safety Division, Bilthoven, The Netherlands
In conclusion, we observed an inverse relationship between adipose tissue DHA and depression, indicating that a high long-term dietary DHA intake lowers the risk of depression. This is the second report on the relationship between adipose tissue DHA and depression in adults. Given the positive relationship between depression and cytokines, such as IL-1, IL-2, IL-6, INF-g and INF-a, the inverse relationship between DHA and depression, may be the result of an inhibiting effect of the particular fatty acid on cytokine synthesis. Other plausible reasons for this relationship may involve possible stimulatory effects on serotonergic and dopaminergic systems as well as neuroprotection against hippocampal neuronal atrophy and volume loss.

EPA but Not DHA Appears To Be Responsible for the Efficacy of Omega-3 Long Chain Polyunsaturated Fatty Acid Supplementation in Depression: Evidence from a Meta-Analysis of Randomized Controlled Trials
Julian G. Martins, MA, MBBS Academy of Nutritional Medicine, Cambridge, UNITED KINGDOM
Background: Epidemiologic and case-control data suggest that increased dietary intake of omega-3 longchain polyunsaturated fatty acids (v3 LC-PUFAs) may be of benefit in depression. However, the results of randomized controlled trials are mixed and controversy exists as to whether either eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA) or both are responsible for the reported benefits. Objective: The aim of the current study was to provide an updated meta-analysis of all double-blind, placebo-controlled, randomized controlled trials examining the effect of v3 LC-PUFA supplementation in which depressive symptoms were a reported outcome. The study also aimed to specifically test the differential effectiveness of EPA versus DHA through meta-regression and subgroup analyses. Design: Studies were selected using the PubMed database on the basis of the following criteria: (1) randomized design; (2) placebo controlled; (3) use of an v3 LC-PUFA preparation containing DHA, EPA, or both where the relative amounts of each fatty acid could be quantified; and (4) reporting sufficient statistics on scores of a recognizable measure of depressive symptoms. Results: Two hundred forty-one studies were identified, of which 28 met the above inclusion criteria and were therefore included in the subsequent meta-analysis. Using a random effects model, overall standardized mean depression scores were reduced in response to v3 LC-PUFA supplementation as compared with placebo (standardized mean difference 5 20.291, 95% CI 5 20.463 to 20.120, z 5 23.327, p 5 0.001). However, significant heterogeneity and evidence of publication bias were present. Meta-regression studies showed a significant effect of higher levels of baseline depression and lower supplement DHA:EPA ratio on therapeutic efficacy. Subgroup analyses showed significant effects for: 1) diagnostic category (bipolar disorder and major depression showing significant improvement with v3 LC-PUFA supplementation versus mild-to-moderate depression, chronic fatigue and non-clinical populations not showing significant improvement); (2) therapeutic as opposed to preventive intervention; (3) adjunctive treatment as opposed to monotherapy; and (4) supplement type. Symptoms of depression were not significantly reduced in 3 studies using pure DHA(standardized mean difference 0.001, 95% CI 20.330 to 0.332, z 5 0.004, p 5 0.997) or in 4 studies using supplements containing greater than 50% DHA (standardized mean difference 5 0.141, 95% CI 5 20.195 to 0.477, z 5 0.821, p 5 0.417). In contrast, symptoms of depression were significantly reduced in 13 studies using supplements containing greater than 50% EPA (standardized mean difference520.446, 95% CI520.753 to 20.138, z 5 22.843, p 5 0.005) and in 8 studies using pure ethyl-EPA (standardized mean difference520.396, 95% CI 5 20.650 to 20.141, z 5 23.051, p 5 0.002). However, further meta-regression studies showed significant inverse associations between efficacy and study methodological quality, study sample size, and duration, thus limiting the confidence of these findings. Conclusions: The current meta-analysis provides evidence that EPA may be more efficacious than DHA in treating depression. However, owing to the identified limitations of the included studies, larger, well-designed, randomized controlled trials of sufficient duration are needed to confirm these finding

Meta-analysis: Effects of Eicosapentaenoic Acid in Clinical Trials in Depression
Objective—Randomized trials of omega-3 polyunsaturated fatty acid (PUFA) treatment for depression have differed in outcome. Recent meta-analyses ascribe discrepancies to differential effects of eicosapentaenoic acid (EPA) vs. docosahexaenoic acid (DHA) and to diagnostic heterogeneity. This meta-analysis tests the hypothesis that EPA is the effective component in PUFA treatment of major depressive episodes.
CONCLUSIONS
Recently, experts have called for more widespread use of omega-3 supplementation in patients at risk for depression10,73. However, there are no current agreed-upon guidelines concerning the optimal balance of constituents in omega-3 supplements. This meta-analysis finds no evidence that DHA is acutely effective against depression, and in fact, it may block beneficial effects of EPA at about a 1:1 dose ratio. Thus the amount of EPA unopposed by DHA may be critical for effective PUFA supplementation in depressive episodes. These findings argue against additional brief clinical trials of DHA for depression. At present, our knowledge base supports the use in acute depression of omega-3 supplements containing at least 60% EPA, with a ceiling at around 2,000 mg of EPA in excess of DHA, although the therapeutic effects of different unopposed EPA doses should be tested further in prospective studies that take into consideration diet and other potential confounds. We note that long term efficacy and health effects of PUFA supplementation in depression have yet to be.
