RESUMEN
Consumption of vitamin-rich fruits and vegetables is emerging as a recommendation for the prevention and treatment of depression and anxiety. This review sought to examine literature investigating the role of kiwifruit in supporting psychological well-being in adult populations through increased vitamin C intake. The literature search using CINAHL, Embase and PubMed databases was restricted to English-language articles published from 2005 through July 2022. Inclusion criteria were randomized trials that delivered kiwifruit interventions to adult populations assessing psychological well-being. Studies were assessed for bias using the Joanna Briggs Institute critical appraisal tool for randomized controlled trials. The literature search identified two eligible trials involving 202 participants that delivered gold kiwifruit interventions and evaluated aspects of psychological well-being (e.g., mood disturbance, vitality, vigour, depression). Daily consumption of two gold kiwifruit was associated with significant reductions in mood disturbance and fatigue, and significant increases in well-being and vigour. Larger effects were observed in participants with higher baseline mood disturbance. Additional research involving a broader range of cohorts and isolating the effects of other micronutrients within gold kiwifruit implicated in the pathophysiology of depression is warranted. Overall, preliminary evidence suggests that daily consumption of two gold kiwifruit might improve psychological well-being in adult populations.

Despite known links between men's avoidant coping behaviours (e.g., distraction, denial, substance use) and suicide risk, little research has explored the mechanisms underpinning this relationship. This study sought to examine whether male-type depression symptoms (e.g., anger, aggression, emotion suppression), assessed by the Male Depression Risk Scale, mediate the association between avoidant coping and suicide/self-harm ideation in men. Data were drawn from an online survey of a community sample of 606 Australian men (M age = 50.11 years; SD = 15.00), conducted during the COVID-19 pandemic. Mediation analyses were applied to examine the effect of male-type depression on the association between avoidant coping and suicidal/self-harm ideation, controlling for age, resilience and the experience of two psychosocial stressors during the COVID-19 pandemic (financial stress and government restrictions). Avoidant coping was associated with suicidal/self-harm ideation, r = 0.45, p < 0.001. Results supported a mediating role of male-type depression symptoms in this relationship, R2= 0.29, PM = 0.36, p < 0.001, underscoring the importance of screening for male-type depression symptoms to better identify men at risk of suicidal/self-harm ideation. Results also suggest a need to support men to develop effective coping strategies, particularly in the context of common psychosocial stressors experienced during the COVID-19 pandemic and beyond.

OBJECTIVES: To develop and validate a short form of the Male Depression Risk Scale (MDRS-22) for use in primary care, examining associations with prototypic depression symptoms, psychological distress and suicidality. DESIGN: Cross-sectional study with 8-month follow-up. SETTING: Community-based. PARTICIPANTS: A community sample of younger (n=510; 18-64 years) and older (n=439; 65-93 years) men residing in Australia (M age=58.09 years, SD=17.77) participated in the study. A subset of respondents (n=159 younger men; n=169 older men) provided follow-up data approximately eight months later. PRIMARY AND SECONDARY OUTCOME MEASURES: Quantitative data were obtained through a survey comprising a range of validated measures, including the MDRS-22, the Patient Health Questionnaire (PHQ-9) and the Kessler Psychological Distress Scale (K10). The MDRS-22 was refined using exploratory and confirmatory factor analysis in line with best practice guidelines. Analysis of variance and generalised linear models were conducted to explore relationships between variables. RESULTS: The short-form MDRS consisted of seven items (MDRS-7) and captured all of the domains in the original tool. Participants with mixed symptoms (PHQ-9 ≥ 10 and MDRS-7 > 5) had significantly higher risk of mental illness (K10 ≥ 25) and current suicidality (PHQ-9 item 9 ≥ 1) than those with exclusively prototypic symptoms (PHQ-9 ≥ 10 and MDRS-7 ≤ 5). Furthermore, the MDRS-7 was shown to be effective at predicting elevated symptoms of depression at follow-up, after controlling for previous depression diagnosis. CONCLUSIONS: Findings provide preliminary evidence of the potential utility of the MDRS-7 as a screening tool for externalised and male-type symptoms associated with major depression in men. Field trials of the MDRS-7 in primary care settings may facilitate identification of men at risk of suicide and psychological distress who do not meet cut-off scores for existing measures of major depression symptoms.

BACKGROUND: The prevalence of depression in men is significantly lower than women despite male suicide being higher. Therefore, improving the understanding and detection of depression in men is an important research and clinical aim. AIMS: To examine the prevalence of prototypic, externalising and mixed depressive symptoms and their relation to mental illness and suicide risk. METHODS: Quantitative data were obtained through a survey of N = 1000 Canadian males (median age = 49.63 years, SD = 14.60). A range of validated scales were incorporated including the PHQ-9, K6, SBQ-R and MDRS. RESULTS: Using established cut-off scores, the proportions classified into distinct symptom groups were: not depressed (69%), prototypical (8%), mixed (12%) and externalising (11%). Risk of mental illness and suicidal risk was significantly elevated in all depressed groups. Compared to the not-depressed group, those experiencing only externalising symptoms and those with mixed symptomology were at significantly increased risk of mental illness as well current suicide risk. CONCLUSION: These results highlight the clinical importance of considering a broad range of potential presentations of depression in men, all of which are associated with increased suicide risk.

BACKGROUND: Due to the coronavirus disease 2019 (COVID-19) pandemic, social distancing practices were introduced to curb infection rates in many countries. The purpose of this study was to assess the effects of these restrictions on behaviours and well-being and whether individual differences predict changes in well-being. METHODS: Australian adults participated in a cross-sectional, online survey during May 2020. The survey captured demographic information; health behaviours; personality traits; life satisfaction and COVID-19-related attitudes, financial concerns, perceived risks and impacts. RESULTS: In total, 3745 (86.8% of 4313) participants completed all items. Participants were mostly female (85.7%) and 56.4 years (standard deviation [SD] = 12.6) on average. Over 95.0% of the sample indicated they had been social distancing or isolating. Health behaviours and well-being had generally worsened, with social connections being the most negatively affected. Life satisfaction was significantly lower since restrictions. For changes in life satisfaction, extroversion was a risk factor and openness to experience was a protective factor. CONCLUSIONS: Overall, well-being was negatively impacted by the COVID-19 pandemic and associated social distancing particularly in this sample containing mainly older women. In future, it will be crucial to understand why and who may be differentially affected, to encourage behaviours that are protective of well-being.

OBJECTIVES: The Male Depression Risk Scale (MDRS-22) is a self-report scale that assesses externalising and male-typical depression symptoms with promising psychometric properties reported in young-to-middle aged men. However, studies are yet to consider the psychometric properties of the MDRS-22 in older men. This study examined the psychometric properties of the MDRS-22 in both younger and older males and its relationship to prototypic depression symptoms and self-reported depression history. METHOD: A community sample of younger (n = 510; 18-64 years) and older (n = 439; 65-93 years) males completed the original 82 MDRS items from which the MDRS-22 was derived, the Patient Health Questionnaire (PHQ-9), and provided information regarding previous depression diagnoses. Exploratory and confirmatory factor analyses were used to examine factor structure. Generalised linear models examined the relationship between externalised and male-typical symptoms with prototypic depression symptoms in younger and older men. RESULTS: Model fit indices demonstrated that the MDRS-22 performs well in older males. Results also revealed that the MDRS-22 is associated with prototypic depression symptoms and a previous depression diagnosis in both age groups. CONCLUSION: Results support the psychometric validity of the MDRS-22 as a measure of externalising and male-typical depression symptoms in older men. Use of scales such as the MDRS-22 may help to improve the detection of depression in men across the lifespan and may also identify factors that put men at risk of poor physical and mental health outcomes.

OBJECTIVES: Measures from wearable devices could be a valuable supplement to mindfulness assessment and intervention. This observational study evaluated measures from a consumer-grade EEG headband (Muse, InteraXon, Inc.) as novel correlates of state mindfulness during focused attention meditation. METHODS: Adult participants (N = 68, M age = 22.66, SD age = 7.35) completed a task-based measure of state mindfulness and thought probe measures of subjective mind wandering while meditating with the EEG headband. A subset completed 14 days of home practice (n = 29). RESULTS: Device measures were sensitive to attention lapses within-participants in the state mindfulness task (d = 0.56) and had large between-participants associations for the same task (r = -0.50). Mean device metrics from home practice together explained approximately 30% of variance in self-reported trait mindfulness, attentional control, nonattachment, and decentering. CONCLUSION: EEG biomarkers show potential as correlates of mindfulness with distinct benefits over existing assessment methods.

AIMS: Very low-carbohydrate (LC) diets are popular for type 2 diabetes (T2DM) management; however, long-term effects on psychological health remain largely unknown. This study reports the effects of a LC diet on mood and cognitive function after 2 years and explores the potential predictors of changes in psychological health. METHODS: 115 adults (57% males; age: 58.5 ± 7.1 years) with obesity and T2DM were randomized to consume an energy reduced (~ 500 to 1000 kcal/day deficit), LC diet [14% energy as carbohydrate, 28% protein, 58% fat (< 10% saturated fat)] or an isocaloric high unrefined carbohydrate, low-fat diet [HC: 53% carbohydrate, 17% protein, 30% fat (< 10% saturated fat)] for 2 years. Both diets were combined with aerobic/resistance exercise (1 h, 3 days/week). Mood/well-being [Beck Depression Inventory (BDI), Spielberger State Anxiety Inventory (SAI), Profile of Mood States (POMS)], diabetes-related quality of life [Diabetes-39 (D-39)] and distress [Problem Areas in Diabetes (PAID) Questionnaire], and cognitive function were assessed during and post-intervention. RESULTS: 61 (LC: 33, HC: 28) participants completed the study. Weight loss was 9.1% after 12 months and 6.7% after 2 years with no difference between diet groups. There were no differences between the groups for the changes in any psychological health outcome (smallest p ≥ 0.19 for all time x diet interactions). Overtime, improvements in BDI, POMS [Total Mood Disturbance (TMD); four subscales], PAID, and D-39 (three subscales) scores occurred (p ≤ 0.05, time). Stepwise regression analysis showed improvements in BDI, POMS (TMD; two subscales), D-39, SAI, and PAID scores were significantly (p < 0.05) correlated with reductions in body weight and glycated hemoglobin. CONCLUSION: In adults with obesity and T2DM, energy-restricted LC and HC diets produced comparable long-term improvements on a comprehensive range of psychological health outcomes. The findings suggest both diets can be used as a diabetes management strategy as part of a holistic lifestyle modification program without concern of negative effects on mental well-being or cognition.

OBJECTIVES: To examine the relationship between depression burden, health service utilisation and depression diagnosis in community-based men. DESIGN: Prospective cohort study. SETTING: Community-based. PARTICIPANTS: Men aged 35-80 years at recruitment (2002-2005), randomly selected from the northern and western suburbs of Adelaide, Australia, without depression at baseline, who attended follow-up visits (2007-2010) (n=1464). PRIMARY AND SECONDARY OUTCOME MEASURES: Depression symptoms were categorised into high burden (total score of ≥13 for the Beck Depression Inventory (BDI) or ≥10 for the Centre for Epidemiologic Studies Depression Scale (CES-D) or low burden (<13 for the BDI or <10 for the CES-D). Diagnosed depression was determined by patient-reported physician diagnosis. Frequent general practitioner (GP) visits were those occurring 5+ times over the preceding year. Use of national medical and prescription services (Medicare Benefit Schedule and Pharmaceutical Benefit Scheme; MBS and PBS) was assessed through data linkage. RESULTS: Frequent attendance and depression diagnosis was more common in men with a high than low burden of depression symptoms (45.9% vs 29.3%-18.7% vs 1.9%, p<0.001). Depression diagnoses were also more common in frequent GP attenders compared with low-average attenders (5.1% vs 2.2%, p<0.001). Among men with high burden of symptoms, there was no age-adjusted or multi-adjusted difference for likelihood of depression diagnosis between non-regular and frequent GP attenders. Annualised MBS and PBS expenditure was highest for men with undiagnosed depression. CONCLUSIONS: Men with a high burden of depression symptoms have commensurate use of health services when compared with those with a low burden, but only half report a physician diagnosis of depression. Undiagnosed depression led to a higher usage of medical and prescription services.

BACKGROUND: Strict adherence to masculine norms has been associated with deleterious consequences for the physical and mental health of men. However, population-based research is lacking, and it remains unclear whether ageing influences adherence to masculine norms and the extent to which mental health problems like depression are implicated. METHODS: This study reports on data from 14,516 males aged 15-55 years who participated in Wave 1 of the Australian Longitudinal Study of Male Health (Ten to Men). Group differences in self-reported conformity to masculine norms (CMNI-22), current depressive symptoms (PHQ-9), and self-reported 12-month depression history were examined for males aged 15-17 years, 18-25 years, 26-35 years, 36-50 years, and 51-55 years. Generalised linear models were used to examine the relationships between these variables across age groups. RESULTS: Conformity to masculine norms decreased significantly with age. However, models predicting depression generally showed that higher conformity to masculine norms was associated with an increased risk of current depressive symptoms, especially in the oldest age group. Conversely, higher conformity was associated with a decreased likelihood of a self-reported 12-month depression history, although nuances were present between age groups, such that this trend was not evident in the oldest age group. CONCLUSIONS: Findings provide important insights into the complex relationship between conformity to masculine norms and depressive symptoms across the lifespan and further highlight the importance of mental health campaigns that address the complexities of gendered help-seeking behaviour for men.

Recent dietary trends have prompted growing support for a variety of fasting paradigms involving extreme restriction or nil-caloric intake on fasting days. Some studies indicate that fasting may negatively influence factors including cognitive function through inducing fatigue, which may prove problematic in the context of completing a range of cognitively demanding activities required by daily obligations such as work. This randomised within-subjects cross-over trial explored the effects of true fasting (i.e., nil-caloric intake) versus modified fasting, the latter of which involved two sub-conditions: (1) extended distribution (three small meals distributed across the day; 522 kcal total); and (2) bulking (two meals eaten early in the day; 512 kcal total) over a period of 7.5 h on a single day with a 7-day washout period between conditions. Participants were n = 17 females (Body Mass Index (BMI) Mean (M) = 25.80, Standard Deviation (SD) = 2.30) aged 21-49 years. Outcomes included cognitive function, subjective mental fatigue, satiety, food cravings and blood glucose. Results showed that there were no differences in cognitive test performance between conditions;however, both modified fasting sub-conditions had improved blood glucose levels, cravings, hunger and fullness compared to true fasting. Moreover, subjective mental fatigue was significantly reduced in the modified fasting conditions relative to true fasting. Overall, results indicated that the subjective experience of true fasting and modified fasting is different, but that cognition does not appear to be impaired.

Despite abundant cross-sectional evidence that low vitamin D status is associated with risk of cognitive decline in ageing, interventional evidence for benefits of vitamin D supplementation is lacking. This study was a 6 month randomised, double-blinded placebo-controlled clinical trial of the effects of vitamin D3 (D3), enhanced vitamin D2 in a mushroom matrix (D2M), standard mushroom (SM) and placebo (PL) on cognition and mood in n = 436 healthy older male (49%) and female volunteers aged ≥ 60 years. Primary end points were change in serum vitamin D metabolites (25-OH-D, 25-OH-D2 and 25-OH-D3), cognitive performance, and mood over 24 weeks. Levels of total 25-OH-D and 25-OH-D3 were maintained in the D3 arm but decreased significantly (p < 0.05) in the remaining arms (D2M, SM and PL). Analysis also revealed differential changes in these metabolites depending on total vitamin D status at baseline. There were no significant effects of treatment on any of the measures of cognitive function or mood. Overall, the results show that daily supplementation of ~600 IU of vitamin D3 was sufficient to maintain 25-OH-D throughout winter months, but in contrast to existing cross-sectional studies there was no support for benefit of vitamin D supplementation for mood or cognition in healthy elderly people.

OBJECTIVE: This study examined the potential acceptability of wearable devices (e.g., smart headbands, wristbands, and watches) aimed at treating mental health disorders, relative to conventional approaches. METHODS: A questionnaire assessed perceptions of wearable and nonwearable treatments, along with demographic and psychological information. Respondents (N = 427) were adults from a community sample (Mage = 44.6, SDage = 15.3) which included current (30.2%) and former (53.9%) mental health help-seekers. RESULTS: Perceived effectiveness of wearables was a strong predictor of interest in using them as adjuncts to talk therapies, or as an alternative to self-help options (e.g., smartphone applications). Devices were more appealing to those with negative evaluations of psychological therapy and less experience in help-seeking. CONCLUSIONS: Interest in using wearable devices was strong, particularly when devices were seen as effective. Clients with negative attitudes to conventional therapies may be more responsive to using wearable devices as a less directive treatment approach.

Objective: Regular screening for colorectal cancer (CRC) can substantially improve outcomes. This study investigated how measuring regret expected from failing to screen might lead to stronger screening intentions. Five potential moderators were evaluated: perceived threat, psychological reactance, prior screening participation, concurrently measuring faecal aversion (FA) and anticipated regret (AR). Design: A 2 (AR measured pre/post intention) × 2 (FA measured pre/post intention) single blind parallel randomised controlled trial was used. Australians aged 45 and over completed an online survey measuring AR, FA, intention, theory of planned behaviour variables and potential moderators. Main outcome measures: The primary outcome was CRC screening intention. Results: Eight hundred and three participants were randomised, with 666 analysed. Measuring AR prior to intention unexpectedly resulted in a significantly lower intention to screen (d = 0.18, 95% CI [0.03, 0.33]) compared to measuring after intention. Trait reactance predicted a significantly lower intention when it was at least 0.52 SD above the mean; other moderators were not supported. Conclusion: The processes underlying anticipated regret manipulations must be better understood in order to have practical value in health promotion. More research is required to determine how to minimise or avoid the apparent negative effects of psychological reactance in CRC screening communication.

Purpose: This study investigated how coping impacts offspring's adaption to parental cancer in terms of post-traumatic growth, resilience, and emotion; and how coping differs between offspring.Methods: Participants (18-34 years; n = 244) completed an online survey. Data were analyzed using generalized linear modeling and multinomial regression.Findings: Higher levels of adaptive coping was associated with higher post-traumatic growth, resiliency, and positive affect; whereas maladaptive coping was associated with lower resiliency and higher negative affect. Females and offspring who did not access support for their parent's cancer reported higher adaptive coping. Offspring bereaved by parental cancer reported higher levels of maladaptive coping. Offspring whose parents' cancer was of shorter duration and those who lived with their ill parent had lower adaptive and maladaptive coping.Conclusions/Implications: Adaptive coping appeared beneficial to offspring. Supportive interventions may benefit from focusing on increasing adaptive coping, particularly among bereaved offspring.

BACKGROUND: Conventional wheat-based foods contain high concentrations of readily digestible starch that commonly give these foods a high postprandial glycemic response and may contribute to the development of type 2 diabetes and cardiovascular disease. OBJECTIVES: The aim of this study was to determine if bread made from high-amylose wheat (HAW) and enriched in resistant starch dampens postprandial glycemia compared with bread made from conventional low-amylose wheat (LAW). METHODS: This single-center, randomized, double-blinded, crossover controlled study involved 7 consecutive weekly visits. On separate mornings, 20 healthy nondiabetic men and women (mean age 30 ± 3 y; body mass index 23 ± 0.7 kg/m2) consumed a glucose beverage or 4 different breads (each 121 g); LAW-R (refined), LAW-W (wholemeal), HAW-R, or HAW-W. The starch contents of the LAW and HAW breads were 24% and 74% amylose, respectively. Venous blood samples were collected at regular intervals before and for 3 h after the breakfast meal to measure plasma glucose, insulin, ghrelin, and incretin hormone concentrations, and the incremental area under the curve (AUC) was calculated (mmol/L × 3 h). Satiety and cravings were also measured at 30-min intervals during the postprandial period. RESULTS: HAW breads had a glycemic response (AUC) that was 39% less than that achieved with conventional wheat breads (HAW 39 ± 5 mmol/L × 3 h; LAW 64 ± 5 mmol/L × 3 h; P < 0.0001). Insulinemic and incretin responses were 24-30% less for HAW breads than for LAW breads (P < 0.05). Processing of the flour (wholemeal or refined) did not affect the glycemic, insulinemic, or incretin response. The HAW breads did not influence plasma ghrelin, or subjective measures of satiety or cravings during the postprandial period. CONCLUSIONS: Replacing LAW with HAW flour may be an effective strategy for lowering postprandial glycemic and insulinemic responses to bread in healthy men and women, but further research is warranted. This trial was registered at the Australian and New Zealand Clinical Trials Registry as ACTRN12616001289404.

OBJECTIVE: Parental cancer is a significant problem for adolescent and young adult offspring. To understand the extent of the problem of parental cancer for Australian offspring, data regarding those impacted are required. The aim of this study was to enumerate and describe the characteristics of Western Australian adolescent and young adult offspring (12-24 years) and their parents with cancer using linked population data. METHODS: A retrospective cohort study was conducted using data from the Western Australia Data Linkage System, which provided results generalisable at a national level. RESULTS: Between 1982 and 2015, 57,708 offspring were impacted by 34,600 parents' incident malignant cancer diagnoses. The most common diagnosis was breast cancer. Of the 36.4% of parents who died, this was mostly a result of cancer. Most families resided in regional areas and were of high or middle socioeconomic status. Significant predictors of earlier parent death included low socioeconomic status, remoteness, age, having more children and having older children. CONCLUSION: A considerable number of adolescent and young adult offspring are impacted by parental cancer at a potentially vulnerable age. This research provides knowledge to better understand who is affected by parental cancer in Australia. Implications for public health: These results may be useful for planning and implementation of Australian supportive services.

Whey protein isolate (WPI) is high in vitamin B12 and folate. These and other related markers (holotranscobalamin, methylmalonic acid and homocysteine) have been linked with cognitive health. This study explored the efficacy of WPI for improving cognitive function via delivery of vitamin B12. Moderately vitamin B12-deficient participants aged between 45 and 75 years (n = 56) were recruited into this randomised controlled crossover trial. Participants (55% female) consumed 50 g whey (WPI; active) or soy protein isolate (SPI; control) for eight weeks. Following a 16-week washout phase, they consumed the alternative supplement. Consumption of WPI significantly improved active B12 and folate status but did not result in direct improvements in cognitive function. However, there was evidence of improvement in reaction time (p = 0.02) and reasoning speed (p = 0.04) in the SPI condition for females. Additional analyses showed that changes in active B12, HcY and folate measures during WPI treatment correlated with improvements in cognitive function (all p < 0.05). Results indicate that WPI itself did not result in improved cognitive function but some evidence of benefit of SPI for females was found. However, consistent with previous research, we present further evidence of a role for active B12, HcY and folate in supporting cognitive improvement in adults with low B vitamin status.

This study reviewed the literature regarding the psychological, social, and behavioural impact of parental cancer on offspring aged 10-24 years, at the time of the parent's first diagnosis. A systematic literature review was conducted following 2015 PRISMA guidelines. Seven studies met inclusion criteria. Offspring were impacted by their parent's cancer and experienced psychological and behavioural problems. Daughters and offspring who experienced more problems at their parent's diagnosis appeared to be most impacted. Offspring refrained from communicating their disease-related concerns, but expected their parents to communicate openly. Turning to oneself and peer-support were coping strategies used by offspring. The majority of offspring were significantly impacted by their parent's cancer. The paucity of literature focusing on offspring aged 10-24â¯yearsâ¯at the time of their parent's incident cancer diagnosis indicates that research has overlooked offspring age at their parent's cancer onset as a factor that may influence their future outcomes.
