RESUMO

Emerging evidence suggests that diet therapy (nutrients, foods and dietary patterns) could be effective as a potential adjunctive treatment option for major depressive disorder. Numerous mechanisms have been proposed, including the role inflammation, oxidative stress, brain-derived neurotrophic factor, the gastrointestinal tract microbiome and tryptophan/serotonin metabolism. Despite known differences in depression characteristics and treatment responses between males and females, there are limited sex-specific studies examining the role of diet in young men specifically. This is important as young men are often reluctant to seek mental health support, so finding treatment strategies which appeal to this demographic is crucial. This brief report provides an overview of the most recent advances in the use of diet for preventing and treating depression in young men, highlighting existing challenges and opportunities for future research. We recommend that clinicians discuss the role of diet with depressed young men, so that diet may be used alongside current treatment options.

RESUMO

Depression is a multifaceted condition with diverse underlying causes. Several contributing and inter-related factors such as genetic, nutritional, neurological, physiological, gut-brain-axis, metabolic and psychological stress factors play a role in the pathophysiology of depression. This review aims to highlight the role that nutritional factors play in the aetiology of depression. Secondly, we discuss the biomedical and functional pathology tests which measure these factors, and the current evidence supporting their use. Lastly, we make recommendations on how practitioners can incorporate the latest evidence-based research findings into clinical practice. This review highlights that diet and nutrition greatly affect the pathophysiology of depression. Nutrients influence gene expression, with folate and vitamin B12 playing vital roles in methylation reactions and homocysteine regulation. Nutrients are also involved in the tryptophan/kynurenine pathway and the expression of brain-derived neurotrophic factor (BDNF). Additionally, diet influences the hypothalamic-pituitary-adrenal (HPA) response and the composition and diversity of the gut microbiome, both of which have been implicated in depression. A comprehensive dietary assessment, combined with appropriate evaluation of biochemistry and blood pathology, may help uncover contributing factors to depressive symptoms. By employing such an approach, a more targeted and personalised treatment strategy can be devised, ultimately leading to improved patient outcomes.

RESUMO

INTRODUCTION: Active duty military personnel and veterans have unique and complex health needs, with the high demands of military life often leading to chronic physical and mental health conditions. Complementary and integrative medicine (CIM) could be a possible solution to this problem. Some military health systems have started integrating CIM into health care delivery. However, there has been no systematic evaluation of the prevalence and utilization of CIM in military and veteran populations globally. MATERIALS AND METHODS: A Preferred Reporting Items For Systematic Reviews and Meta-Analysis Protocols protocol was used to systematically search for original research assessing the prevalence and utilization of CIM among active serving military or veterans. CINAHL, MEDLINE, Scopus, and AMED databases were searched up to February 3, 2023. RESULTS: A total of 27 studies met the inclusion criteria and were included in this review. The overall quality of evidence was high with a low risk of bias. Utilization of CIM varied. The lowest utilization demonstrated that only 1.9% of services delivered by military health system were CIM. The majority of studies found utilization rates between 30% and 80%, with some studies reporting use as high as 90%. The most commonly used CIM therapies included chiropractic care, massage, mindfulness/meditation, and acupuncture. Utilization of CIM products was high and ranged from 32% to 87%. The most frequently used products were dietary supplements, particularly multivitamins and minerals and protein supplements/amino acids. The use of herbal products was high among veterans ranging from 10% to 79%. CONCLUSIONS: The high demand for CIM by military personnel and veterans has important implications for policy, funding allocation, and integration of these services into clinical practice, particularly by countries not currently doing so. Further research is needed to assess the implementation of CIM into real-world settings to explore barriers and facilitators for their use in clinical practice and, by extension, their integration into the wider health care system.

RESUMO

BACKGROUND: Recent research has highlighted the beneficial effects of following a Mediterranean diet (MD) for depression. Unfortunately, adherence to specific diets presents many challenges and while previous research has aimed to understand these challenges, the focus has primarily been on weight-loss interventions in patients with obesity or cardiovascular disease. The aim of this study was to understand the experiences and challenges expressed by young men with clinical depression who completed a 12-week Mediterranean diet intervention. METHODS: An online questionnaire was used to collect data from 36 young Australian men aged between 18 and 25 with diagnosed depression who participated in the Mediterranean Diet arm of the Mediterranean Diet for Men with Depression (AMMEND) study. Descriptive analyses were undertaken for each variable with results reported as percentages and frequencies. RESULTS: Positive aspects highlighted by participants included enjoying the taste of foods, being highly motivated to continue with the diet and a perceived benefit to their depressive symptoms. The main challenges included increased cost and time commitment, and the negative attitudes of their friends and family towards the diet. CONCLUSION: We recommend that the influence of friends and family attitudes towards the diet and the impact this has on following a Mediterranean diet in young men be explored further, as this posed a challenge for many of our participants. These results may assist clinicians when promoting a Mediterranean diet to this specific demographic.

RESUMO

BACKGROUND: Stroke represents a major source of mortality and morbidity worldwide. Guidelines for stroke management and secondary prevention focus on reducing stroke-related risk factors such as smoking cessation, exercise and diet. Several clinical practice guidelines specifically recommend a Mediterranean diet (MD) for individuals with stroke. However, these recommendations rely primarily on observational research. The aim of this review is to critically appraise the current experimental evidence assessing the use of a Mediterranean diet on health outcomes in post-stroke adults. METHODS: A systematic literature review was conducted of original research which assessed the role of a Mediterranean diet on health outcomes in post-stroke adults. The following databases were searched: PROQUEST, SCOPUS (Elsevier), MEDLINE (EBSCO), EMBase and Cochrane Library up to the 25th of August 2021. RESULTS: A total of 6 studies from a total of 5838 identified studies met the full inclusion criteria and were included in this review. Several different health outcomes were assessed, including blood pathology tests, physical examinations, secondary vascular events and mortality. The Mediterranean diet appears to be beneficial for systolic and diastolic blood pressure, LDL cholesterol, BMI and waist circumference. CONCLUSION: This review suggests a Mediterranean diet may be helpful for several health outcomes in post-stroke adults. However, more research is needed to confirm these findings. To ensure robust methodology and replication of results, specific details of the included and excluded foods, quantities and serving sizes should be reported in future research.

RESUMO

BACKGROUND: Fatigue is a common and often debilitating symptom experienced by many stroke survivors. Significant post stroke fatigue may predispose individuals to other health complications, such as falls, which can lead to fractures and soft tissue injuries. Only limited research has examined the association between fatigue and falls in stroke survivors. METHODS: Data were obtained from the Sax Institute's 45 and Up Study, from a subset of individuals who had experienced a stroke. The Modified Fatigue Impact Scale-5-item version (MFIS-5) was used to measure the level of fatigue. A logistic regression model, adjusted for stroke characteristics and comorbidities, was used to determine the magnitude of association between change in fatigue score and odds of having had a fall. RESULTS: A total of 576 participants completed the questionnaire. A total of 214 (37.2%) participants reported having had a fall in the previous 12 months. There was a statistically significant association between fatigue scores and fall status (p < 0.001). Specifically, for every 1-point increase in the fatigue score (MFIS-5) (i.e. higher level of fatigue), the odds of a person having a fall is 1.10 times greater (AOR = 1.10; 95% CI 1.05, 1.15; p < 0.001). CONCLUSION: This study revealed an association between an increasing risk of falls with increasing severity of post stroke fatigue. Accurate detection and management of fatigue may help reduce the risk of falls and should be the focus of future research.

RESUMO

BACKGROUND: Stroke is a major public health problem worldwide, as more people survive their initial stroke event and subsequently live with chronic disability. While extensive research has focused upon preventing primary strokes comparatively little research has examined secondary stroke prevention. METHODS: We analysed data collected from a survey of 576 participants from the 45 and Up Study who had a clinical diagnosis of stroke. Health status was assessed using a variety of validated instruments. Demographics and modifiable risk factors, including health behaviours and diagnosed conditions, were also measured. Logistic regression model building was used to examine the relationship between each modifiable risk factor and the independent variables of demographics and health status measures. RESULTS: The average time since the most recent stroke for study participants was 10.4 (SD = 8.9) years, with the majority of participants (73.2%) having had only one stroke in total. Regression modelling revealed that health-related hardiness, quality of life, depression and fatigue scores were all statistically significantly associated with heart disease, anxiety, depression and physical activity. For stroke characteristics, years since the most recent stroke was associated with heart disease and the number of strokes was associated with anxiety/nervous disorder, diabetes and alcohol consumption. CONCLUSION: Among other identified targets for secondary stroke prevention, fatigue and depressive symptoms appear to be common factors affecting several modifiable stroke risk factors. Addressing fatigue and depressive symptoms may therefore have a positive effect on secondary stroke prevention strategies in post stroke adults. All practitioners providing care for post-stroke adults can work towards improving these health factors thereby enhancing and prioritising secondary stroke prevention strategies.

RESUMO

BACKGROUND: Stroke is a common cause of mortality and morbidity which affects approximately 17 million people globally each year. Common symptoms associated with stroke are physical disabilities, impaired cognitive functions, depression, and fatigue, all of which can significantly impact health-related quality of life (HRQoL). To date, no research has explored the inter-relationship among fatigue, disability, depression, health-related hardiness, and quality of life in stroke survivors. METHODS: Data was obtained from a sub-study of the 45 and Up Study; including 576 Australian adults who had been diagnosed with a stroke. The cross-sectional questionnaire obtained demographic and health status information, as well as clinical measures and stroke-related measures. Associations among fatigue and disability, depression, health-related hardiness and quality of life were analysed using a linear regression model. RESULTS: In comparison to those participants with no stroke-related disability, those with slight (ß = 1.141; p = 0.008), moderate (ß = 3.250; p < 0.001) or severe (ß = 3.526; p < 0.001) disability had significantly higher fatigue scores. For every one unit increase in the depression score, the fatigue score increased by 1.502 points (p < 0.001). For every one unit increase in the health-related hardiness score, the fatigue score decreased by 0.054 points (p = 0.044). For every one unit increase in the quality of life score, the fatigue score decreased by 0.068 points (p < 0.001). CONCLUSION: This study found significant associations among fatigue and disability, depression, health-related hardiness, and quality of life in stroke survivors. Accurate detection and management of fatigue may help improve the rehabilitation of stroke survivors.

RESUMO

BACKGROUND: Depression is a common mental health condition that affects 1 in 8 males each year, especially young adults. Young adulthood offers an opportunity for early dietary interventions, with research suggesting that a Mediterranean diet (MD) could be beneficial in treating depression. OBJECTIVES: This study aimed to determine if an MD can improve depressive symptoms in young males with clinical depression. METHODS: A 12-wk, parallel-group, open-label, randomized controlled trial was conducted to assess the effect of an MD intervention in the treatment of moderate to severe depression in young males (18-25 y). Befriending therapy was chosen for the control group. Assessments were taken at baseline, week 6, and week 12. MD adherence was measured with the Mediterranean Diet Adherence Score (MEDAS). The primary outcome measure was the Beck Depression Inventory Scale-version II (BDI-II) and secondary outcome was quality of life (QoL). RESULTS: A total of 72 participants completed the study. After 12 wk, the MEDAS scores were significantly higher in the MD group compared with the befriending group (mean difference: 7.8; 95% CI: 7.23, 8.37; P < 0.001). The mean change in BDI-II score was significantly higher in the MD group compared with the befriending group at week 12 (mean difference: 14.4; 95% CI: 11.41, 17.39; P < 0.001). The mean change in QoL score was also significantly higher in the MD group compared with the befriending group at week 12 (mean difference: 12.7; 95% CI: 7.92, 17.48; P < 0.001). CONCLUSIONS: Our results demonstrate that compared with befriending, an MD intervention leads to significant increases in MEDAS, decreases in BDI-II score, and increases in QoL scores. These results highlight the important role of nutrition for the treatment of depression and should inform advice given by clinicians to this specific demographic population.The trial was registered with Australia and New Zealand Clinical Trials Registry (trial ID ACTRN12619001545156) and has also been registered with the WHO International Clinical Trials Registry Platform (Universal Trial Number U1111-1242-5215).

RESUMO

OBJECTIVE: Stroke is a major cause of mortality and disability worldwide. People with stroke have a number of options available to treat post-stroke related symptoms and challenges. The aim of this study was to assess the use of healthcare services, self-care practices and out-of-pocket expenses associated with post-stroke healthcare. METHODS: We retrospectively analysed data collected between April and October 2017 from a survey of 576 participants aged 55 to 96 from the 45 and Up Study, NSW (Australia), who had earlier reported a clinical diagnosis of stroke. Participants were asked about their use of health care services, including conventional medicine practitioners and medications, complementary medicine practitioners, practices and products and the respective associated out-of-pocket expenditure for each. RESULTS: Amongst the total of 576 individuals who participated in the study, 39% consulted a doctor, 18% consulted an allied health practitioner, and 8% consulted a complementary medicine practitioner in the previous year for their stroke. Participants' average combined out-of-pocket expenditure for post-stroke related healthcare was AU$386.4 per annum. Extrapolated to all Australians with stroke, aged 55 years and over, the total out-of-pocket expenditure for post-stroke related healthcare is estimated to be AU$42 million per annum. CONCLUSIONS: Post-stroke individuals used a wide range of health services and various self-care practices for stroke rehabilitation. Such healthcare utilisation is associated with significant annual out-of-pocket expenditure. Given the socioeconomic burden of stroke, further research is required to identify the barriers and facilitators of self-care among patients with stroke and explore the cost-effectiveness of the wide range of treatments(s) utilised for post-stroke care.

RESUMO

OBJECTIVE: To examine the use and out-of-pocket expenses resulting from consultations, products and practices across conventional, self-care, and complementary medicine (CM) treatments for osteoarthritis (OA) among Australian women. DESIGN, SETTING AND PARTICIPANTS: A cross-sectional survey of 800 women from the 45 and Up Study who had reported a clinical diagnosis of OA. OUTCOME MEASURES: Women's use of conventional, CM and self-prescribed treatments for OA and the associated out-of-pocket cost. RESULTS: Completed questionnaires were returned by 403 women (50.4%). Their average time since the first diagnosis of OA was 15.4 years, and self-rated severity of OA was 5.1 (out of 10) over the past 12 months. During the previous year, 67.0% of the women consulted a doctor, 39.2% consulted an allied health practitioner and 34.7% consulted a CM practitioner for their OA. Some women (19%) consulted with practitioner(s) from all three practitioner groups, 27% consulted with practitioner(s) from two of the three practitioner groups, while 6% consulted with a CM practitioner only. Women with a greater time since diagnosis had more consultations, as did women who rated their OA as more severe. Women's average combined out-of-pocket expenditure for OA-related healthcare consultations, prescription medications, products, and practices was $673 per annum. Extrapolated to all Australian women with OA, aged 50 years and over, the total out-of-pocket expenditure for this condition is estimated to be $873 million per annum. CONCLUSIONS: Australian women with OA use a range of conventional and CM consultations, self-care, products and practices to manage their condition, incurring significant out-of-pocket expenses. Given the high individual and societal burden of OA, there is a need for further research into the concurrent use of different healthcare resources with a view to providing safe, cost-effective management of OA across the healthcare system and the wider community.

RESUMO

This research aimed to determine the health care cost and utilisation of older Australian women with osteoporosis. A wide range of healthcare services were used and approximately AU$593.9 was spent over a 12-month period for these services. This highlights the significant cost burden of osteoporosis on the healthcare system. PURPOSE: Osteoporosis is a common skeletal condition among women that has a considerable impact on quality of life. The purpose of this study is to determine the prevalence of healthcare use and to estimate associated out-of-pocket expenditure for the management of osteoporosis in older Australian women. METHODS: Data was obtained from 393 Australian women from the 45 and Up Study who had osteoporosis. The women were asked about healthcare use for their osteoporosis, including conventional medicine, complementary medicine, and self-care practices or self-care products, and associated out-of-pocket expenditure for that use over 12 months. RESULTS: The average age of participants was 72.0 years. Over a 12-month period, the majority of participants (72%) consulted a doctor for their osteoporosis, 24% consulted an allied health practitioner, and 20% consulted a complementary medicine practitioner. Participants had a mean of 6.8 consultations with healthcare practitioners in the previous 12 months for the osteoporosis. In addition, 46% participants used three or more types of complementary medicine products/practices in the previous 12 months. Overall, the participants incurred a (arithmetic) mean ofAU$594 (median = $350; inter-quartile range = $450) in out-of-pocket expenditure for healthcare use over the 12-month period. CONCLUSIONS: Women with osteoporosis use a wide range of healthcare services that are associated with significant annual out-of-pocket expenditure. Preventive strategies can help decrease the cost burden of osteoporosis on the healthcare system.

RESUMO

Depression affects approximately 350 million people worldwide. Evidence suggests that diet plays an important role with the Mediterranean diet (MD) displaying promising preliminary results. Currently, most of the research is conducted on women and older adults; however, the majority of mental illnesses occur before the age of 25 years. Men are less likely to seek help than women with only 13 % of young men aged 15-24 years seeking help for their mental health. Young men are hugely underrepresented in the current research which poses a significant issue. A 12-week randomised controlled trial will be conducted to examine the effect of a MD on the symptoms of depression in young men aged 18-25 years. Participants will be randomised to either follow a MD or receive the inactive control therapy befriending. Participants will attend three appointments at baseline, week 6 and week 12. The main outcome will be changes to the Beck's Depression Inventory score. This research aims to answer the question of whether diet can be used effectively in this population. This will be the first trial to examine the effect of a MD on the symptoms of depression in young men. This trial will help fill a significant research gap, contribute to the growing field of nutritional psychiatry, guide future research and inform advice given by clinicians to this specific demographic.

RESUMO

OBJECTIVES: Currently 1 million Australians are living with depression each year, with an average of one in eight men experiencing the disorder. Studies have shown that individual nutrients, fruit and vegetable intake, polyphenols, and whole dietary patterns can have a positive effect on depressive symptoms. In particular, the Mediterranean diet has shown promising preliminary findings. The aim of this study was to assess the diet quality and knowledge of young men in relation to depressive symptoms. METHODS: This was a cross-sectional online survey. We collected data from 384 young Australian men between 18 and 25 y of age with diagnosed depression. Pearson's χ2 test was used for ordinal categorical variables. RESULTS: Dietary intake among this population was poor. Discretionary foods were consumed two to three times per week and included pizza (41%), fried potatoes such as French fries or hash browns (29%), and chocolate (25%). Roughly half of participants (47%) reported never consuming whole grains or legumes and only 9% said they eat vegetables twice or more per day. Healthy eating is perceived as both time consuming (82%) and expensive (70%). One-third (32%) of participants perceived their diet as having a major effect and 29% a slight effect on their mental health, with only 5% reporting that diet has no effect on their mental health. However, the majority of participants (84%) believe it is important or very important to eat an overall healthy diet and 77% reported being willing to change their diet if it would improve their symptoms of depression. CONCLUSIONS: These results highlighted the relatively poor diets of this population. This group of young men would greatly benefit from a quality diet such as the Mediterranean diet. The reported willingness to change their diets is encouraging and supports the viability of dietary intervention trials in this demographic. The dietary data presented in this study can be used to develop targeted interventions aimed at improving the diets of young men with depression.

RESUMO

Depression is a mood disorder which currently affects 350 million individuals worldwide. Recently, research has suggested a protective role of diet for depression. The Mediterranean-style dietary pattern has been highlighted in several systematic reviews as a promising candidate for reducing depressive symptoms. It has been speculated that this could be due to the high polyphenol content of foods commonly found in the diet. Therefore, the aim of this review was to assess the effects of polyphenols found in a Mediterranean diet on the symptoms of depression. A systematic literature review was conducted of original research which assessed the role of polyphenols on the symptoms of depression in humans. The following databases were searched: PROQUEST, SCOPUS (Elsevier), MEDLINE (EBSCO), CINAHL, and EMBase, up to 18 February, 2019. The inclusion criteria consisted of both observational and experimental research in adults aged 18-80 y that assessed depression scores in relation to polyphenol intake. A total of 37 studies out of 12,084 met the full inclusion criteria. Of these, 17 were experimental studies and 20 were observational studies. Several different polyphenols were assessed including those from tea, coffee, citrus, nuts, soy, grapes, legumes, and spices. Twenty-nine of the studies found a statistically significant effect of polyphenols for depression. This review has found both an association between polyphenol consumption and depression risk, as well as evidence suggesting polyphenols can effectively alleviate depressive symptoms. The review uncovered gaps in the literature regarding the role of polyphenols for depressive symptoms in both young adults and men. This review was registered at www.crd.york.ac.uk/PROSPERO as CRD42019125747.

RESUMO

BACKGROUND AND AIMS: Folate is an essential nutrient required for many different functions in the body. It is particularly important for DNA synthesis, immune functions, and during pregnancy. Folate supplements are commonly prescribed by health professionals for a number of different conditions, however, the absorption of the different derivatives remains unclear. The aim of this review was to assess the bioavailability of various forms of folate supplements in healthy populations and animal models. METHODS: A systematic literature review was conducted of original research, which assessed the bioavailability of different oral forms of folate in healthy adults or animal models. The following databases were searched: PubMed (U.S. National Library of Medicine), ProQuest Medical Collection (ProQuest) and ScienceDirect (Elsevier) up to March 30, 2017. The inclusion criteria consisted of both animal and human research, no disease state or condition, and assessed levels after an intervention of a folate derivative. RESULTS: A total of 23 studies out of 5226 met the full inclusion criteria. Of these, 4 were animal studies and 19 were human studies. There was variation in supplement forms used with the most commonly tested being folic acid followed by 5-methylenetetrahydrofolate (5-MTHF). Dosages ranged from 25 µg up to 200 mg. Only three studies found a statistically significant difference in folate bioavailability when evaluating different supplement forms. These studies found 5-MTHF to be more effective at increasing folate levels in participants. CONCLUSIONS: This review has found a number of methodological limitations and conflicting results. Only three out of the 23 studies assessed found a statistically significant difference between different supplemental forms of folate. Quality absorption studies assessing the bioavailability of oral folate supplements are crucial if clinicians are to make effective evidence-based recommendations. More research is required for greater clarification regarding the bioavailability of these supplements.
