Stress and anxiety are frequent occurrences among pregnant women. Mental disorders can appear before pregnancy, with a changing course during pregnancy and postpartum. During pregnancy, evidence has been provided regarding the potential beneficial effects that structured dietary interventions based on a Mediterranean diet (MedDiet) can have, not only on pregnant women, but also their offspring and the pregnancy itself. The aim of this study was to evaluate the influence of a structured intervention during pregnancy based on a MedDiet on maternal stress and anxiety, mindful state, quality of life and sleep. This study is a parallel, unblinded randomised clinical trial. Participants - pregnant women at high risk for small-for-gestational-age newborns - were randomly assigned (1:1:1) to one of the three study groups: a MedDiet supplemented with extra-virgin olive oil and walnuts; a stress reduction intervention based on the Mindfulness-Based Stress Reduction (MBSR) programme; or usual care without any intervention (control group). Results show that an intervention based on MedDiet during pregnancy: - significantly improved well-being and sleep quality. - is associated with a reduction in maternal anxiety/stress, together with an increase in the cortisol-deactivating enzyme. Authors conclude that a MedDiet intervention significantly reduces maternal anxiety and stress, as well as improving well-being and sleep quality during gestation.
Abstract
Stress and anxiety are frequent occurrences among pregnant women. We aimed to evaluate the effects of a Mediterranean diet intervention during pregnancy on maternal stress, well-being, and sleep quality throughout gestation. In a randomized clinical trial, 1221 high-risk pregnant women were randomly allocated into three groups at 19-23 weeks' gestation: a Mediterranean diet intervention, a Mindfulness-Based Stress Reduction program, or usual care. All women who provided self-reported life-style questionnaires to measure their anxiety (State Trait Anxiety Inventory (STAI), Perceived Stress Scale (PSS)), well-being (WHO Five Well Being Index (WHO-5)), and sleep quality (Pittsburgh sleep quality index (PSQI)) at enrollment and at the end of the intervention (34-36 weeks) were included. In a random subgroup of 106 women, the levels of cortisol and related metabolites were also measured. At the end of the intervention (34-36 weeks), participants in the Mediterranean diet group had significantly lower perceived stress and anxiety scores (PSS mean (SE) 15.9 (0.4) vs. 17.0 (0.4), p = 0.035; STAI-anxiety mean (SE) 13.6 (0.4) vs. 15.8 (0.5), p = 0.004) and better sleep quality (PSQI mean 7.0 ± 0.2 SE vs. 7.9 ± 0.2 SE, p = 0.001) compared to usual care. As compared to usual care, women in the Mediterranean diet group also had a more significant increase in their 24 h urinary cortisone/cortisol ratio during gestation (mean 1.7 ± SE 0.1 vs. 1.3 ± SE 0.1, p < 0.001). A Mediterranean diet intervention during pregnancy is associated with a significant reduction in maternal anxiety and stress, and improvements in sleep quality throughout gestation.

Children exposed to early life stress (ELS) show alterations in brain development and are at increased risk of developing mental illness. This study aims to clarify whether ELS influences the gut microbiome and whether this can be a predictor for the development of mental disorders. 13 articles were included in this systemic review. 4 looked at pre-natal stress and 9 at post-natal stress. Prenatal stress (via maternal stress) may be associated with an increase in Proteobacteria phylum and with a lower abundance of Bifidobacterium and lactic acid bacteria. In the postnatal group, greater microbiome diversity was related to lower depression and anxiety. In boys scores for adaptive skills were higher in those with good levels of Bifidobacterium. A positive association was found between EA (early adversity) experiences and gastrointestinal symptoms and anxiety. This review demonstrates links between ELS and gut microbiome changes. Further research will be necessary to draw more robust conclusions.

Summary Review:
Introduction
A systematic review was conducted to consolidate clinical evidence examining the impact of early life stress (ELS) on the human intestinal microbiome.
Method
Thirteen observational studies were included in the review, sourced from Pubmed, Scopus, Web of Science, and EMBASE. Methodological quality was assessed using the Newcastle-Ottawa Assessment Scale (NOS), with most studies scoring seven or eight out of nine stars.
Study designs varied, including prospective prenatal studies, postnatal longitudinal studies, case-control studies, and cross-sectional studies. Four prenatal studies were prospective in design. The other nine postnatal studies included one longitudinal study, five case-control studies, and three cross-sectional studies. All 13 studies were published between 2015 and 2022. Because study designs and outcome assessments varied, the results were presented in a narrative form. Data was extracted by 2 independent authors.
Results
The primary findings from the review were as follows:
- Four longitudinal stress studies indicated that pregnant mothers experiencing psychological stress, increased cortisol levels, HIV, and lack of social support exhibited a lower abundance of beneficial Bifidobacterium and an increased abundance of Enterobacter genus.
- One postnatal stress longitudinal study (n=260) demonstrated lower depression and anxiety and improved internalising behaviour in patients with high microbiome diversity.
- . One postnatal stress case-control study (n=344) showed changes in the microbiome and an abundance of several bacterial taxa in stressed groups, including genera Prevotella, Bacteroides (Bacteroidetes), Coprococcus, Streptococcus, and Escherichia.
- One cross-sectional study of 128 adults without psychiatric conditions revealed that higher stress correlated with increased levels of Bacteroides, Parabacteroides, Rhodococcus, Methanobrevibacter, and Roseburia at the genus level, as well as lower Phascolarcto bacterium and Firmicutes at the phylum level.
- One large prospective study (n=446) found infants exposed to higher cumulative stress exhibited an increased relative abundance of Proteobacteria groups and lower Bifidobacterium.
Conclusion:
Due to the inconsistency of study designs and their results this review failed to find consensus microbiome signatures associated with pre- or postnatal stress, or both.
Clinical practice applications:
- Early life stress, and alterations in the gut microbiome, have been linked to mental health conditions
- Maternal prenatal stress may be linked to emotional, behavioural, and cognitive outcomes in infants.
Considerations for future research:
- Future research should standardise questionnaires, to ensure consistency and comparability across studies
- Additionally, future studies should consider using standard procedures and specific species and strain resolution shotgun metagenomics sequencing
- Consideration should be given to the influence of environmental variables (diet, physical activity, etc.) and sex in gut microbiome analysis.
Abstract
Exposure to early life stress (ELS), prenatal or postnatal during childhood and adolescence, can significantly impact mental and physical health. The role of the intestinal microbiome in human health, and particularly mental health, is becoming increasingly evident. This systematic review aims to summarize the clinical data evaluating the effect of ELS on the human intestinal microbiome. The systematic review (CRD42022351092) was performed following PRISMA guidelines, with ELS considered as exposure to psychological stressors prenatally and during early life (childhood and adolescence). Thirteen articles met all inclusion criteria, and all studies reviewed found a link between ELS and the gut microbiome in both prenatal and postnatal periods. However, we failed to find consensus microbiome signatures associated with pre- or postnatal stress, or both. The inconsistency of results is likely attributed to various factors such as different experimental designs, ages examined, questionnaires, timing of sample collection and analysis methods, small population sizes, and the type of stressors. Additional studies using similar stressors and validated stress measures, as well as higher-resolution microbiome analytical approaches, are needed to draw definitive conclusions about the links between stress and the human gut microbiome.

Plain language summary
Previous research has shown a bidirectional relationship between the gut and psychological stress, which could be mediated by intestinal permeability followed by an immune and inflammatory response. However, the exact mechanisms of this relationship are yet to be elucidated. This randomised, double-blind, placebo-controlled trial evaluated the beneficial effects of Lactobacillus rhamnosus CNCM I-3690 on intestinal permeability and stress markers during a public speech in healthy students. Participants consumed either milk containing Lactobacillus rhamnosus CNCM I-3690 or acidified milk twice daily for four weeks to assess subjective and objective stress markers and markers of intestinal permeability. Lactobacillus rhamnosus CNCM I-3690 reduced the stress-induced hyperpermeability to mannitol and subjective stress markers (State-Trait Anxiety Inventory/ STAI). A subgroup of healthy students with stress-induced cortisol >P90 of baseline showed a reduction in perceived stress score following Lactobacillus rhamnosus CNCM I-3690 intervention. To evaluate the additional effects of Lactobacillus rhamnosus CNCM I-3690 on stress and gut health, further robust studies are needed. Healthcare professionals can use the findings of this study to understand the anxiolytic effects of Lactobacillus rhamnosus CNCM I-3690.
Abstract
Psychological stress negatively affects the intestinal barrier function in animals and humans. We aimed to study the effect of Lactobacillus rhamnosus CNCM I-3690 on intestinal permeability and stress-markers during public speech. Healthy students were randomized to L. rhamnosus-containing (test) or acidified (placebo) milk consumed twice daily for 4 weeks, with 46 subjects per treatment group. Small intestinal permeability was quantified by a 2 h urinary lactulose-mannitol ratio (LMR, primary outcome), fractional excretion of lactulose (FEL) and mannitol (FEM). Salivary cortisol, State-Trait Anxiety Inventory (STAI) and Perceived Stress scores (PSS) were collected. No between-treatment differences were found for LMR (p = .71), FEL or FEM. Within-treatment analyses showed similar LMR and FEL but a stress-induced increase of FEM with the placebo (p < .05) but not test product. Despite a similar increase in salivary cortisol, the stress-induced increase in STAI was significantly lower with the test product vs. placebo (p = .01). Moreover, a stress-preventative effect of the probiotic was found for PSS and more pronounced in subjects with high stress-induced cortisol (p = .01). While increased FEM was mediated by salivary cortisol levels, the effect of the test product on subjective stress was not mediated by changes in FEM. No serious adverse events occurred. In conclusion, we demonstrated that L. rhamnosus CNCM I-3690 prevented stress-induced hyperpermeability to mannitol. Subjective but not objective stress-markers were reduced with L. rhamnosus vs. placebo, suggesting anxiolytic effects, which were independent of barrier stabilization and attractive for the reduction of stress in both health and disease.

Plain language summary
Coronavirus disease 2019 (COVID-19) is an infectious disease caused by the respiratory syndrome coronavirus 2 (SARS-CoV-2). To curb the spread of the 2020 pandemic, social distancing, self-isolation and nationwide lockdown measures were put in place. These measures along with hygiene care are recognized as the most effective ways to curb the spread of disease. However; the weakening of social contacts can result in anxiety, frustration, panic attacks, loss or sudden increase of appetite, insomnia, depression, mood swings, delusions, fear, sleep disorders, and suicidal/domestic violence. The purpose of the study is to provide scientific data to help identify risk factors for the psychosocial strain during the COVID-19 outbreak. The study is an international cross-disciplinary online survey and was circulated in April 2020. 1047 replies were analysed from this preliminary phase. The results show a significant difference in all tested parameters and therefore reveal a large burden for mental wellbeing combined with a tendency towards an unhealthy lifestyle during, compared to before, the confinement enforced by the COVID-19 pandemic. These results highlight the importance for policy makers to consider strategies to promote wellbeing during future confinements.
Abstract
Although recognised as effective measures to curb the spread of the COVID-19 outbreak, social distancing and self-isolation have been suggested to generate a burden throughout the population. To provide scientific data to help identify risk factors for the psychosocial strain during the COVID-19 outbreak, an international cross-disciplinary online survey was circulated in April 2020. This report outlines the mental, emotional and behavioural consequences of COVID-19 home confinement. The ECLB-COVID19 electronic survey was designed by a steering group of multidisciplinary scientists, following a structured review of the literature. The survey was uploaded and shared on the Google online survey platform and was promoted by thirty-five research organizations from Europe, North Africa, Western Asia and the Americas. Questions were presented in a differential format with questions related to responses "before" and "during" the confinement period. 1047 replies (54% women) from Western Asia (36%), North Africa (40%), Europe (21%) and other continents (3%) were analysed. The COVID-19 home confinement evoked a negative effect on mental wellbeing and emotional status (P < 0.001; 0.43 ≤ d ≤ 0.65) with a greater proportion of individuals experiencing psychosocial and emotional disorders (+10% to +16.5%). These psychosocial tolls were associated with unhealthy lifestyle behaviours with a greater proportion of individuals experiencing (i) physical (+15.2%) and social (+71.2%) inactivity, (ii) poor sleep quality (+12.8%), (iii) unhealthy diet behaviours (+10%), and (iv) unemployment (6%). Conversely, participants demonstrated a greater use (+15%) of technology during the confinement period. These findings elucidate the risk of psychosocial strain during the COVID-19 home confinement period and provide a clear remit for the urgent implementation of technology-based intervention to foster an Active and Healthy Confinement Lifestyle AHCL).

Plain language summary
Diet, mental health, and well-being are linked through several biological pathways. In addition to a healthy diet, nutrient supplements may be of benefit due to their ability to influence these pathways. This review aimed to outline the relationship between specific nutrients and their beneficial effect on mental health. The review outlined the various benefits of polyunsaturated fats, vitamin E, magnesium and folic acid on stress, anxiety, sleep disorders, mild cognitive impairment, depression, bipolar disorders, and obsessive-compulsive disorder. With regards to stress, it was outlined that insufficient vitamins, excessive fat and nutritional imbalance can be contributory. Human research exists to support the benefits of magnesium and polyunsaturated fat for stress and these plus vitamin E for anxiety, however it appears that evidence is lacking for vitamin E and stress and the authors did not comment on folic acid for either condition. Extensive research exists for the use of polyunsaturated fats in mild cognitive impairment, and it was stated that high doses for long periods of time may be needed to show any benefits. The use of vitamin E in cognitive impairment is controversial and more studies may be needed. The authors did not comment on magnesium or folic acid supplementation. It was concluded that an unhealthy diet and lifestyle may be associated with poor mental health and well-being and the importance of a balanced, varied diet for normal brain function. This study could be used by healthcare professionals to understand the importance of recommending a healthy diet for mental well-being in individuals who are suffering from mental health disorders.
Abstract
A good nutritional status is important for maintaining normal body function and preventing or mitigating the dysfunction induced by internal or external factors. Nutritional deficiencies often result in impaired function, and, conversely, intakes at recommended levels can resume or further enhance body functions. An increasing number of studies are revealing that diet and nutrition are critical not only for physiology and body composition, but also have significant effects on mood and mental well-being. In particular, Western dietary habits have been the object of several research studies focusing on the relationship between nutrition and mental health. This review aims to summarize the current knowledge about the relationship between the intake of specific micro- and macronutrients, including eicosapentaenoic acid, docosahexaenoic acid, alpha-tocopherol, magnesium and folic acid, and mental health, with particular reference to their beneficial effect on stress, sleep disorders, anxiety, mild cognitive impairment, as well as on neuropsychiatric disorders, all significantly affecting the quality of life of an increasing number of people. Overall data support a positive role for the nutrients mentioned above in the preservation of normal brain function and mental well-being, also through the control of neuroinflammation, and encourage their integration in a well-balanced and varied diet, accompanied by a healthy lifestyle. This strategy is of particular importance when considering the global human aging and that the brain suffers significantly from the life-long impact of stress factors.

Plain language summary
Stress and low magnesemia are shown to be linked by previous research evidence. Additionally, Vitamin B6 (pyridoxine) has been shown to have stress-relieving and neuromodulating effects. This 1:1 randomised, investigator-blinded, parallel-group trial compared the effectiveness of magnesium alone and a combination of magnesium and vitamin B6 in participants with moderate to severe stress on mental and physical health. Participants consumed 300 mg magnesium lactate dihydrate daily with 30 mg Vitamin B6 or 300 mg magnesium lactate dihydrate daily for 8 weeks. Treatment with magnesium with or without vitamin B6 improved depression and anxiety, specifically a significant improvement observed after week four of the intervention. Quality of life improvements were sustained over 8 weeks among participants with magnesemia. Combined supplementation of magnesium and vitamin B6 increased the perceived capacity for physical activity in participants. Further robust research is needed to evaluate the combined effects of vitamin B6 and magnesium on stress-related mental health in people with magnesemia. However, healthcare professionals can use the results of this study to better understand magnesium and vitamin B6 supplementation's positive effects on stress-related mental health.
Abstract
Magnesium status and vitamin B6 intake have been linked to mental health and/or quality of life (QoL). In an 8-week Phase IV randomised controlled study in individuals with low magnesemia and severe/extremely severe stress but who were otherwise healthy, greater stress reduction was achieved with magnesium combined with vitamin B6 than with magnesium alone. We present a previously unreported secondary analysis of the effect of magnesium, with and without vitamin B6, on depression, anxiety, and QoL. Adults with Depression Anxiety Stress Scales (DASS-42) stress subscale score >18 were randomised 1:1 to magnesium + vitamin B6 combination (Magne B6® ; daily dose 300 and 30 mg, respectively) or magnesium alone (Magnespasmyl® ; daily dose 300 mg). Outcomes included changes from baseline in DASS-42 depression and anxiety scores, and QoL (Short Form-36 Health Survey). DASS-42 anxiety and depression scores significantly improved from baseline to week 8 with both treatments, particularly during the first 4 weeks. Improvement in QoL continued over 8 weeks. Participants' perceived capacity for physical activity in daily life showed greater improvement with magnesium + vitamin B6 than magnesium alone (Week 4). In conclusion, magnesium supplementation, with or without vitamin B6, could provide a meaningful clinical benefit in daily life for individuals with stress and low magnesemia.

Plain language summary
Synbiotic, a mixture of prebiotics and probiotics, is known to improve neurotransmitter interactions, immune, inflammatory, and stress responses by modulating the gut microbial composition. It is also believed that physical activity plays an important role in the modulation of immune function and stress response. The purpose of this triple-blinded, randomized, placebo-controlled pilot study was to evaluate the health benefits of symbiotic intervention in fourteen sedentary students and thirteen soccer players, especially in terms of improving immunophysiological and metabolic parameters. The 300mg of symbiotic intervention contained Bifidobacterium lactis CBP-001010, Lactobacillus rhamnosus CNCM I-4036, Bifidobacterium longum ES1(109 colony-forming unit), and fructooligosaccharides (200 mg) plus 1.5 mg of zinc, 8.25 µg of selenium, 0.75 µg of vitamin, and maltodextrin. Following a one-month intervention with synbiotic formulation, soccer players showed improvements in anxiety, sleep quality and stress, a slight reduction in proinflammatory cytokine IL-1β, an exercise-induced significant increase in dopamine and a slight elevation of corticotropin-releasing hormone. For confirmation of results of this pilot study and to assess more significant effects of symbiotic intervention in athletes as well as in the general population, longer-term robust studies are required. The findings of this study can help healthcare professionals understand the extensive health benefits of synbiotic intervention and its relationship to physical activity.
Abstract
The main objective of this research was to carry out an experimental study, triple-blind, on the possible immunophysiological effects of a nutritional supplement (synbiotic, Gasteel Plus®, Heel España S.A.U.), containing a mixture of probiotic strains, such as Bifidobacterium lactis CBP-001010, Lactobacillus rhamnosus CNCM I-4036, and Bifidobacterium longum ES1, as well as the prebiotic fructooligosaccharides, on both professional athletes and sedentary people. The effects on some inflammatory/immune (IL-1β, IL-10, and immunoglobulin A) and stress (epinephrine, norepinephrine, dopamine, serotonin, corticotropin-releasing hormone (CRH), Adrenocorticotropic hormone (ACTH), and cortisol) biomarkers were evaluated, determined by flow cytometer and ELISA. The effects on metabolic profile and physical activity, as well as on various parameters that could affect physical and mental health, were also evaluated via the use of accelerometry and validated questionnaires. The participants were professional soccer players in the Second Division B of the Spanish League and sedentary students of the same sex and age range. Both study groups were randomly divided into two groups: a control group-administered with placebo, and an experimental group-administered with the synbiotic. Each participant was evaluated at baseline, as well as after the intervention, which lasted one month. Only in the athlete group did the synbiotic intervention clearly improve objective physical activity and sleep quality, as well as perceived general health, stress, and anxiety levels. Furthermore, the synbiotic induced an immunophysiological bioregulatory effect, depending on the basal situation of each experimental group, particularly in the systemic levels of IL-1β (increased significantly only in the sedentary group), CRH (decreased significantly only in the sedentary group), and dopamine (increased significantly only in the athlete group). There were no significant differences between groups in the levels of immunoglobulin A or in the metabolic profile as a result of the intervention. It is concluded that synbiotic nutritional supplements can improve anxiety, stress, and sleep quality, particularly in sportspeople, which appears to be linked to an improved immuno-neuroendocrine response in which IL-1β, CRH, and dopamine are clearly involved.

Plain language summary
Besides the high infection and mortality rate, the COVID-19 pandemic also causes considerable psychological stress. Research from previous epidemics and pandemics found that health concerns and anxieties relating to a virus outbreak can have a significant psychological impact and have been linked to behaviours ineffective for disease prevention. Health anxiety exists on a spectrum from absent health awareness to pathological health anxiety or hypochondria. Unhelpful practices, such as excessive online information searching (cyberchondria) or doctor visits can amplify or sustain such anxieties. Furthermore, media consumption during a pandemic has been positively associated with anxiety, and so has been related to dysfunctional emotion regulation (i.e. ruminating, catastrophizing). So far, it was assumed that individuals with pre-existing health anxiety are particularly prone to experience virus anxiety with little numerical evidence to back this up. Hence this study sought to quantify whether during the COVID -19 pandemic, pre-existing health anxiety influenced levels of virus anxiety and whether there was a relationship between cyberchondria and virus anxiety. An online survey was conducted within the German population in March 2020 (N = 1615, female predominant, mean age of = 33.36 years) and data was collected using a series of questionnaires. The outcome was consistent with previous studies showing that about half of the participants reported moderate to severe anxiety associated with COVID-19, women being particularly affected. Predisposition to health anxiety and cyberchondria were consistently positively correlated to virus anxiety. Whereby being well informed and having coping strategies seemed to contribute to reduced levels of virus anxiety. The study may be of interest to those who seek evidence on the association between health anxiety and media consumption in relation to pandemic-associated anxiety.
Abstract
According to cognitive-behavioral models, traits, triggering events, cognitions, and adverse behaviors play a pivotal role in the development and maintenance of health anxiety. During virus outbreaks, anxiety is widespread. However, the role of trait health anxiety, cyberchondria, and coping in the context of virus anxiety during the current COVID-19 pandemic has not yet been studied. An online survey was conducted in the German general population (N = 1615, 79.8 % female, Mage = 33.36 years, SD = 13.18) in mid-March 2020, which included questionnaires on anxiety associated with SARS-CoV-2, trait health anxiety, cyberchondriaPandemic (i.e. excessive online information search), and emotion regulation. The participants reported a significantly increasing virus anxiety in recent months (previous months recorded retrospectively), especially among individuals with heightened trait health anxiety. CyberchondriaPandemic showed positive correlations with current virus anxiety (r = .09-.48), and this relationship was additionally moderated by trait health anxiety. A negative correlation was found between the perception of being informed about the pandemic and the current virus anxiety (r=-.18), with adaptive emotion regulation being a significant moderator for this relationship. The findings suggest that trait health anxiety and cyberchondria serve as risk factors, whereas information about the pandemic and adaptive emotion regulation might represent buffering factors for anxiety during a virus pandemic.

Plain language summary
Fibromyalgia is a syndrome with unknown cause, characterised by muscle pain and physical exhaustion and is especially common in women aged 20-55 years. Anxiety, mood disturbance and psychological disorders are also often reported. Two micronutrients found in food, which may be of benefit to fibromyalgia patients are tryptophan (TRY) and magnesium (MG). This randomised control trial aimed to determine the effects of a Mediterranean diet supplemented with TRY and MG in 22 women with fibromyalgia for 16 weeks. The results showed that supplementation improved anxiety, mood, eating disorders and body image, but did not affect sleep quality. It was concluded that Mediterranean diet supplemented with TRY and MG was of benefit to anxiety, depression and reduced eating disorders but did not affect sleep quality. This study could be used by healthcare professionals to recommend a Mediterranean diet enriched with TRY and MG to improve symptoms of depression and anxiety in women with fibromyalgia.
Abstract
Anxiety, mood disturbance, eating and sleep disorders, and dissatisfaction with body image are prevalent disorders in women with fibromyalgia. The authors of this study aimed to determine the effects of tryptophan (TRY) and magnesium-enriched (MG) Mediterranean diet on psychological variables (trait anxiety, mood state, eating disorders, self-image perception) and sleep quality in women with fibromyalgia (n = 22; 49 ± 5 years old). In this randomized, controlled trial, the participants were randomly assigned to the experimental group and the placebo group. The intervention group received a Mediterranean diet enriched with high doses of TRY and MG (60 mg of TRY and 60 mg of MG), whereas the control group received the standard Mediterranean diet. Pittsburgh Sleep Quality Questionnaire, Body Shape Questionnaire, State-Trait Anxiety Inventory (STAI), Profile of Mood States (POMS-29) Questionnaire, Eating Attitudes Test-26, and Trait Anxiety Inventory were completed before and 16 weeks after the intervention. Significant differences were observed between groups after the intervention for the mean scores of trait anxiety (p = 0.001), self-image perception (p = 0.029), mood disturbance (p = 0.001), and eating disorders (p = 0.006). This study concludes that tryptophan and magnesium-enriched Mediterranean diet reduced anxiety symptoms, mood disturbance, eating disorders, and dissatisfaction with body image but did not improve sleep quality in women with fibromyalgia.

Plain language summary
Anxiety treatments currently involve medication and changing an individual’s beliefs through cognitive behavioural therapy (CBT). Art therapy (AT) is often used as a CBT treatment strategy, although little is known about its effectiveness. This randomised control trial of 47 adult women with anxiety aimed to understand the role of AT in anxiety treatment over three months. The results showed improvements in self-reported measures of anxiety, the ability to control emotions, memory and the ability to manage tasks with AT, however subjects were just as susceptible to stress following treatment. It was concluded that anxiety reduction was related to improvements in emotions, memory and task management and this was as a result of AT. This study could be used by healthcare professionals to recommend AT to individuals with symptoms of anxiety as part of their treatment management plan.
Abstract
OBJECTIVES To explore possible working mechanisms of anxiety reduction in women with anxiety disorders, treated with art therapy (AT). METHODS A RCT comparing AT versus waiting list (WL) condition on aspects of self-regulation. Stress regulation (heart rate and heart rate variability) and executive functioning (daily behavioural and cognitive performance aspects of executive functioning (EF)) were evaluated in a pre-post design. Participants were women, aged 18-65 years with moderate to severe anxiety symptoms. RESULTS Effectiveness of AT compared to WL was demonstrated in a higher resting HRV post treatment, improvements in aspects of self-reported daily EF (emotion control, working memory, plan/organize and task monitor), but not in cognitive performance of EF, stress responsiveness and down regulation of stress. The decrease in anxiety level was associated with improvements in self-reported daily EF. CONCLUSIONS AT improves resting HRV and aspects of EF, the latter was associated with art therapy-related anxiety reduction.
