What do young Australian adults know about modifiable risk factors for dementia?

BACKGROUND: There are well established modifiable risk factors for late-life dementia. These risk factors account for over 30% of population attributable dementia risk and accrue over the lifespan. Young adults have the greatest potential to reduce their own risk for dementia. This study aimed to investigate what young Australian adults know about dementia and its risk factors, and further, how they estimated these risks. METHODS: An online survey promoted through various social media platforms was completed by 604 young Australian adults aged 18-44 years of age. RESULTS: Seventy percent of participants had a limited understanding of dementia (identifying cognitive or functional impairment), 25% had a good understanding, with 5% having no understanding. Twenty percent of respondents thought there were no modifiable risk factors for dementia. Less the half of participants agreed with two of the nine established dementia risk factors (hearing loss in midlife and education in early life), with over half of participants agreeing to the remaining seven risk factors. Females consistently judged the risks conferred by the nine established dementia risk factors to be higher than males. Those who were lonely judged the dementia risk conferred by loneliness to be higher than those who were not lonely; and smokers judged the dementia risk conferred by smoking to be less than non-smokers. CONCLUSION: Young adults have the greatest potential to change their dementia risk, and these findings show that there are important gaps in knowledge of dementia and its risk factors in this group.

Cognitive late effects following allogeneic stem cell transplantation in haematological cancer patients.

OBJECTIVE: The objective of this exploratory study was to determine the presence and correlates of self-reported cognition in a sample of haematological cancer patients who had undergone allogeneic stem cell transplantation (SCT). METHODS: Haematological cancer patients (n = 30) who had undergone allogeneic SCT between one and five years previously and age-matched control participants (n = 30) completed questionnaires assessing cognition, affect, sleep quality and fatigue and an assessment of premorbid IQ. RESULTS: Patients reported significantly poorer perceived cognitive ability (d = 1.12) and greater perceived cognitive impairment (d = 0.96) than controls. Lower fatigue was significantly associated with greater perceived cognitive ability (r = 0.75 patients and controls) and less perceived cognitive impairment (r = 0.80 patients; r = 0.57 controls). Interestingly, depression was significantly correlated with perceived cognitive ability in the control group only (r = 0.80). Hierarchical multiple regressions showed that fatigue was a significant predictor of perceived cognitive ability in patients, accounting for 56% of the variance. CONCLUSIONS: This study established that self-reported cognitive ability and cognitive impairment was significantly poorer in haematological cancer patients than controls. Furthermore, fatigue was significantly associated with perceived cognitive ability in patients. Future research should focus on identifying interventions that target fatigue in allogeneic SCT recipients in order to improve quality of life throughout survivorship.

How coming out and community involvement affects body image: An in-depth examination of lesbian women's personal experiences.

Research on body image commonly focuses on the negative aspects of the construct, and the majority of findings related to body image in general arise from quantitative methods of investigation. Furthermore, little is known about the experiences lesbian women go through as they come out, and what consequence this has on their body image. In this study we examined the experiences of 12 lesbian women and explored how coming out affected their body image. Data were collected via face-to-face interviews and analyzed using thematic analysis. Participants' ages ranged from 20 to 33 (M = 25). The analysis revealed that all participants reported experiencing improved body image after coming out. Other changes related to the presentation of sexual identity in terms of how they dressed, i.e., presenting as either more masculine or feminine. Most participants reported feeling that the sexual and gender minority community was more accepting of different body shapes and sizes compared to the heteronormative society in which they resided. Negative feelings and experiences related to family situations, and occasionally from within themselves. The results are important in understanding how gender and sexual orientation are intertwined to create a distinct experience of body image in lesbian women, and also to illustrate the heterogeneity of body image within subgroups of women.

Are the protective benefits of vitamin D in neurodegenerative disease dependent on route of administration? A systematic review.

Background: The clinical and preclinical exploration of the therapeutic properties of vitamin D have significantly increased in the past decade, owing to the growing associative evidence suggesting vitamin D is neuroprotective. However, whether depletion of vitamin D contributes to the onset of neurological disorders or is a symptom of neurological disease has yet to be defined. Much remains unclear about the causal role of vitamin D and the method of use and forms of vitamin D.Objectives: We sought to quantitatively assess if neuroprotective benefits from vitamin D in neurodegenerative diseases are dependent on route of administration: comparing the effect of endogenously sourced vitamin D from UV exposure to exogenously derived vitamin D through synthetic supplementation.Design: We systematically searched PubMed, Embase and PsycInfo databases which included both pre-clinical and clinical studies investigating vitamin D in neurodegenerative diseases. Articles were subject to strict inclusion criteria and objectively assessed for quality. Additionally, Medline data was analysed to identify trends in topic publications and linguistic characteristics of papers.Results: From a total of 231 screened articles, we identified 73 appropriate for review based on inclusion criteria: original studies that investigated vitamin D levels or levels of vitamin D supplementation in neurodegenerative diseases or investigated past/present sun exposure in disease cohorts. Results indicate there is insufficient evidence to comprehensively reflect on a potential neuroprotective role for vitamin D and if this was dependent on route of administration. The majority of current data supporting neuroprotective benefits from vitamin D are based on pre-clinical and observational studies. Solid evidence is lacking to support the current hypothesis that the beneficial effect of UV exposure results from the synthesis of vitamin D. Sun exposure, independent of vitamin D production, may be protective against multiple Sclerosis, Parkinson's disease and Alzheimer's disease. Yet, further research is required to elucidate the beneficial mechanism of actions of UV exposure. The literature of vitamin D and amyotrophic lateral sclerosis was limited, and no conclusions were drawn. Therefore, in cases where UV-derived vitamin D was hypothesized to be the beneficial mediator in the neuroprotective effects of sun exposure, we propose results are based only on associative evidence.Conclusion: On the basis of this systematic review, strong recommendations regarding therapeutic benefits of vitamin D in neurodegenerative disease cannot be made. It is unclear if vitamin D mediates a protective benefit in neurodegenerative disease or whether it is an associative marker of UV exposure, which may contribute to as of yet unidentified neuroprotective factors.

Diet and cognitive function in cancer survivors with cancer-related cognitive impairment: A qualitative study.

OBJECTIVE: To identify cancer survivors' perceptions of the role diet plays in their cognitive function, and how their cancer-related cognitive changes influence their diet. METHODS: Cancer survivors diagnosed with cancer in the past 5 years, not on active treatment, and with self-reported cognitive changes since diagnosis were recruited from the general population. Semi-structured interviews were conducted with 15 Australian breast (n = 13) and colorectal (n = 2) survivors (mean time since diagnosed: 27.0 months ± SD=16.8). Questions related to how their diet and cognitive changes influenced each other. Interviews were recorded, and transcripts were analysed using thematic analysis. RESULTS: Four themes related to how diet impacted cognition: (a) directly (e.g. healthy diet improves cognition), (b) indirectly (e.g. diet affects tiredness which affects cognition); (c) no impact; and (d) potentially (e.g. poorer diet quality would worsen cognition). Three themes emerged for how cognitive changes were thought to impact survivors' diets: (a) planning meals is harder; (b) cooking is more difficult and complex; and, (c) choosing healthy is more challenging. CONCLUSIONS: Many cancer survivors perceived a bidirectional influence between diet and cognition that has cognitive and behavioural consequences. Diet could be investigated as a modifiable lifestyle behaviour to improve cancer-related cognitive impairment and fatigue. Survivors may benefit from dietary guidance with meal planning and preparing.

Anorexia nervosa and perfectionism: A meta-analysis.

OBJECTIVE: Despite the multitude of research surrounding anorexia nervosa (AN) and perfectionism, there is yet to be a thorough investigation comparing perfectionism in those diagnosed with AN and other eating disorders, and other psychiatric diagnoses. The current meta-analysis aimed to explore these comparisons. METHOD: Following the Preferred Reporting Items or Systematic Reviews Meta Analyses (PRISMA) guidelines, we identified empirical studies that compared maladaptive and/or adaptive perfectionism scores in those diagnosed with AN and either a non-clinical comparison group, people diagnosed with a non-AN ED, or people diagnosed with another psychological disorder (i.e., other DSM diagnoses). In total, we identified 23 studies, comprising 3,561 participants who were all female. Comparison groups extracted from the studies were a non-clinical group, bulimia nervosa (BN) diagnosis group, and another psychological diagnostic group. RESULTS: When AN maladaptive perfectionism levels were compared against the comparison groups, the results showed that those diagnosed with AN were more perfectionistic compared to the non-clinical group (g = 1.00), and the other psychiatric diagnosis group (g = 0.41). People diagnosed with AN also had higher levels of adaptive perfectionism levels compared to the non-clinical group (g = 1.24). Comparisons between those diagnosed with AN and BN were statistically non-significant for maladaptive perfectionism. DISCUSSION: Although publication bias potentially affected the psychological diagnosis group comparisons, findings suggest that maladaptive perfectionism is a factor associated with both AN and BN.

Treatment outcome research of enhanced cognitive behaviour therapy for eating disorders: a systematic review with narrative and meta-analytic synthesis.

Enhanced cognitive behaviour therapy (CBT-E) has recently generated interest as a potentially useful treatment for eating disorders (ED). In the current study, we conducted a systematic review of the outcome literature on CBT-E, with both narrative and meta-analytic synthesis. We included single-group uncontrolled pre-post design studies and randomised control trials (RCTs) of CBT-E, which allowed us to include a larger number of studies, and also compare the two methodologies in terms of effect size. The primary analysis included 15 CBT-E studies with a total of 948 participants. Narrative synthesis examined bingeing and purging episodes, BMI change, and follow-up results. A large, statistically significant effect supported CBT-E as a treatment for all EDs (g = 1.06). When comparing methodologies, both pre-post design studies (g = 1.26) and RCTs (g = 0.82) yielded large effects. Narrative synthesis outlined reductions in ED behaviours and increases in BMI which were maintained at follow-up. Limitations include that further RCTs of CBT-E are needed to establish clinical effectiveness of this treatment approach for all EDs; however, results from narrative exploration indicate this endeavour would be worthwhile. Despite the limitations, this study provides additional support for CBT-E as a successful treatment across the range of EDs.

The efficacy of cognitive interventions for improving cognitive performance and academic achievement in children after cancer treatment: A systematic review.

Academic decline has been reported in children after cancer treatment, believed to be as a result of cognitive impairment. Cognitive interventions may improve both the present and future outcomes for children after cancer treatment by improving cognitive and/or academic performance. This review aimed to examine the efficacy of cognitive interventions in children who had received cancer treatment. A systematic search of the PsycInfo and PubMed databases was conducted in May 2015 to identify studies in which cognitive interventions were conducted with children who had undergone cancer treatment and were under the age of 21. Cognitive or academic outcomes needed to be reported pre- and post-intervention to meet the inclusion criteria. Eleven studies were included in this review. Computerized and home-based cognitive interventions were found to be most successful at improving cognitive skills. However, few cognitive interventions assessed academic achievement specifically. Future cognitive intervention research studies should include measures of academic achievement outcomes, because academic achievement and cognitive outcomes may differ. Future research regarding the effectiveness of early, home-based and computerized intervention is warranted.

Acculturation, Skin Tone Preferences, and Tanning Behaviours Among Young Adult Asian Australians.

Australia has a significant proportion of residents of Asian heritage. Although the incidence of skin cancer is lower in those of Asian heritage than Caucasians, their prognosis is often worse. Sociocultural variables are central to the tanning behaviours of individuals from Western cultures. We examined the role of sociocultural variables in the tanning behaviours (outdoor tanning, indoor/solarium and fake tan use) among Asian Australians. A sample of 399 young adults identifying either as a person of Asian heritage or as Asian Australian participated in an online survey. Our results suggest that Asian Australians are at risk of skin cancer; over 35 % of the sample reported engaging in outdoor tanning and over 10 % in solarium tanning. After controlling for demographic factors and skin cancer knowledge, preferring a darker skin tone and being acculturated to Australia were significantly associated with tanning behaviour. Participants' low levels of skin cancer knowledge are of concern, and possibilities for improving knowledge levels in this group are considered. Further, we recommended that future research studies investigate sociocultural and appearance-related beliefs associated with tanning behaviours in this population, in order to determine best avenues for intervention.

Skin Tone Dissatisfaction, Sun Exposure, and Sun Protection in Australian Adolescents.

PURPOSE: This study aimed to assess the adoption of sun protection and sun exposure behaviors, the extent to which these behaviors group together, and the relationship between skin tone dissatisfaction and sun-related behaviors in South Australian adolescents (aged 12-17). METHODS: A total of 2,875 secondary school students (1,461 male and 1,414 female) completed a questionnaire including questions about sun protection and sun exposure behaviors and skin tone dissatisfaction. RESULTS: Regular adoption of sun protection behaviors was low and ranged from 20% (wearing protective clothing) to 44% (sunscreen use). A principal components analysis identified four subgroups of sun-related behaviors: sun protection, appearance enhancement, sun avoidance, and sun exposure. Females had significantly higher skin tone dissatisfaction than males. Skin tone dissatisfaction was associated with decreased sun protection and avoidance and increased appearance enhancement and sun exposure in both males and females. CONCLUSIONS: Skin tone dissatisfaction plays an important role in Australian adolescents' sun-related behavior. Appearance-based interventions may be effective in reducing skin cancer risk through reduced sun exposure.

Watching reality weight loss TV. The effects on body satisfaction, mood, and snack food consumption.

The present study investigated the influence of a weight loss reality TV show on body satisfaction, mood and food consumption. Young Australian women (N = 99) first completed baseline measures of state body satisfaction and mood. They were then randomly allocated to either a weight loss or a home renovation programme and were provided with snack foods during viewing. Post-measures included state body satisfaction, state mood and trait dietary restraint and snack food consumption. BMI moderated the relationship between condition and body satisfaction and mood. Larger women experienced less body satisfaction and less positive mood in response to the weight loss programme. Dietary restraint moderated the relationship between condition and food consumption. A greater percentage of women with lower dietary restraint ate in the control condition; whilst a greater percentage of women with higher dietary restraint ate food whilst watching the weight loss programme. These findings highlight the potential negative impact of weight-focused reality TV on mood, body satisfaction and snack food consumption among some women.

Perceptions of the solarium ban in Australia: 'Fake it, don't bake it'.

ISSUE ADDRESSED: The causal link between ultraviolet radiation from solarium use and skin cancer is well established. In 2012 and 2013, state governments across Australia announced plans to ban commercial solarium use from 31 December 2014. The present study examined the responses of solarium and non-solarium users to the ban on commercial solariums in Australia. METHODS: Participants (n = 488; 388 females, 100 males; mean age = 26.02, s.d. = 9.95) completed an online questionnaire during the summer prior to the ban relating to solarium usage and their opinions about the ban. RESULTS: Overall, 49% (n = 237) of participants were aware of the impending ban; 17% (n = 83) had used a solarium at some point in their life. The response to the solarium ban was positive; however, some current solarium users intended post-ban to use privately owned sunbeds and or spend a greater amount of time sun-tanning. CONCLUSIONS: These findings indicate a high level of public support for the solarium ban, which has removed a risky source of ultraviolet radiation in Australia. SO WHAT? Further steps are now needed to monitor the tanning behaviours of previous solarium users post-ban and their access to private sunbed use and other potentially dangerous methods of tanning (e.g. tanning injections).

What causes breast cancer? A systematic review of causal attributions among breast cancer survivors and how these compare to expert-endorsed risk factors.

PURPOSE: The aim of this paper was to review published research that analyzed causal attributions for breast cancer among women previously diagnosed with breast cancer. These attributions were compared with risk factors identified by published scientific evidence in order to determine the level of agreement between cancer survivors' attributions and expert opinion. METHODS: A comprehensive search for articles, published between 1982 and 2012, reporting studies on causal attributions for breast cancer among patients and survivors was undertaken. Of 5,135 potentially relevant articles, 22 studies met the inclusion criteria. Two additional articles were sourced from reference lists of included studies. RESULTS: Results indicated a consistent belief among survivors that their own breast cancer could be attributed to family history, environmental factors, stress, fate, or chance. Lifestyle factors were less frequently identified, despite expert health information highlighting the importance of these factors in controlling and modifying cancer risk. This review demonstrated that misperceptions about the contribution of modifiable lifestyle factors to the risk of breast cancer have remained largely unchanged over the past 30 years. CONCLUSIONS: The findings of this review indicate that beliefs about the causes of breast cancer among affected women are not always consistent with the judgement of experts. Breast cancer survivors did not regularly identify causal factors supported by expert consensus such as age, physical inactivity, breast density, alcohol consumption, and reproductive history. Further research examining psychological predictors of attributions and the impact of cancer prevention messages on adjustment and well-being of cancer survivors is warranted.

Does mindfulness matter? Everyday mindfulness, mindful eating and self-reported serving size of energy dense foods among a sample of South Australian adults.

Serving size is a modifiable determinant of energy consumption, and an important factor to address in the prevention and treatment of obesity. The present study tested an hypothesised negative association between individuals' everyday mindfulness and self-reported serving size of energy dense foods. The mediating role of mindful eating was also explored. A community sample of 171 South Australian adults completed self-report measures of everyday mindfulness and mindful eating. The dependent measure was participants' self-reported average serving size of energy dense foods consumed in the preceding week. Participants who reported higher levels of everyday mindfulness were more mindful eaters (r=0.41, p<0.05) and reported smaller serving size estimates of energy dense foods (r=-.25, p<0.05). Mindful eating fully mediated the negative association between everyday mindfulness and serving size. The domains of mindful eating most relevant to serving size included emotional and disinhibited eating. Results suggest that mindful eating may have a greater influence on serving size than daily mindfulness.

Validity and reliability of the Food-Life Questionnaire. Short form.

Measures of beliefs and attitudes towards food need to be valid, and easy to use and interpret. The present study aimed to establish the validity and reliability of a short-form of the Food-Life Questionnaire (FLQ). Participants (247 females; 118 males), recruited in South Australia, completed a questionnaire in 2012 incorporating the original FLQ, a revised short form (FLQ-SF), and measures of food choice and consumption. Validity (construct, criterion-related, and incremental) and reliability (internal consistency and short-form) were assessed. Factor analysis established that short-form items loaded onto five factors consistent with the original FLQ and explained 60% of variance. Moderate correlations were observed between the FLQ-SF and a measure of food choices (r=.32-.64), and the FLQ-SF predicted unhealthy food consumption over and above the full FLQ demonstrating criterion-related and incremental validity respectively. The final FLQ-SF included 21 items and had a Cronbach's alpha of .75. Short-form reliability was established with correlations between corresponding subscales of the FLQ and FLQ-SF ranging from r=.64-.84. Overall, the FLQ-SF is brief, psychometrically robust, and easy to administer. It should be considered an important tool in research informing public policies and programs that aim to improve food choices.

The role of body awareness and mindfulness in the relationship between exercise and eating behavior.

This study examined the potential mediating roles of mindfulness and body awareness in the relationship between exercise and eating behavior. Female exercisers (N = 159) recruited from fitness centers, yoga centers, and the community completed a questionnaire incorporating measures of exercise behavior, body awareness, trait mindfulness, mindful eating, dietary intake, and disordered eating symptoms. Participation in yoga was associated with significantly lower disordered eating (mediated by body awareness), whereas the amount of time spent participating in cardio-based exercise was associated with greater eating disturbance. The relationships between amount of exercise and actual food intake were not mediated by trait mindfulness or body awareness. The differential findings for dietary intake and disordered eating indicate that the body awareness cultivated in different forms of exercise may be more beneficial for clinical populations or those at risk for eating disorders than for modifying actual dietary intake in the general population.

Effectiveness of Operation K9 Assistance Dogs on Suicidality in Australian Veterans with PTSD: A 12-Month Mixed-Methods Follow-Up Study.

Post-traumatic stress disorder (PTSD) is a pervasive disorder among both current and ex-serving Australian Defence Force (ADF) members. Studies have shown current psychological and pharmacological treatments for PTSD are suboptimal in veterans, with high dropout rates and poor adherence to treatment protocols. Therefore, evaluating complementary interventions, such as assistance dogs, is needed for veterans who may not receive the ultimate benefit from traditional therapies. The present longitudinal mixed-method study examined the effectiveness of Operation K9 assistance dogs among sixteen veterans with PTSD, specifically, their effects on suicidality, PTSD, depression, and anxiety from baseline to 12 months post-matching. Self-reported measures were completed prior to receiving their dog (baseline) and at three time points (3, 6, and 12 months) following matching. The Clinician-Administered PTSD Scale for DSM-5 was used to assess the severity of every PTSD case. Veterans participated in a semi-structured interview 3 months post-matching. Whilst there was a reduction in the proportion of veterans reporting any suicidality, there was no significant change in the probability of veterans reporting suicidality between time points. There was a significant effect of time on PTSD, depression, and anxiety symptoms. Three major themes emerged from qualitative data analysis: life changer, constant companion, and social engagement. Qualitative data suggest assistance dogs can have a positive impact on important areas of daily life and support veterans in achieving some of the prerequisites for health, including access to services, transport, education, employment, and development of new and diverse social and community connections. Connections were key in improving health and wellbeing. This study exemplifies the power of human-animal relationships and adds emphasis to the need to take these seriously and create supportive healthy environments for veterans with PTSD. Our findings could be used to inform public health policy and service delivery, in line with the Ottawa Charter action areas and indicate that for veterans with PTSD, assistance dogs may be a feasible adjunct intervention.

Improving nutrition and physical activity in the workplace: a meta-analysis of intervention studies.

A comprehensive search of the literature for studies examining physical activity or nutrition interventions in the workplace, published between 1999 and March 2009, was conducted. This search identified 29 relevant studies. Interventions were grouped according to the theoretical framework on which the interventions were based (e.g. education, cognitive-behavioural, motivation enhancement, social influence, exercise). Weighted Cohen's d effect sizes, percentage overlap statistics, confidence intervals and fail safe Ns were calculated. Most theoretical approaches were associated with small effects. However, large effects were found for some measures of interventions using motivation enhancement. Effect sizes were larger for studies focusing on one health behaviour and for randomized controlled trials. The workplace is a suitable environment for making modest changes in the physical activity, nutrition and health of employees. Further research is necessary to determine whether these changes can be maintained in the long term.

Dietary Drivers and Challenges of Australian Breast Cancer Survivors: A Qualitative Study.

Purpose: Cancer survivors often make long-term dietary changes, and nutrition is important for survivorship outcomes. Many survivors experience persisting cognitive difficulties, which can impact health behaviors. This study aimed to identify perceived drivers of eating habit changes, and the barriers to making intentional dietary changes, among breast cancer survivors with persisting self-reported cancer-related cognitive impairment. Materials and Methods: A qualitative framework explored survivors' perceptions of dietary habit changes. Thirteen Australian breast cancer survivors (M.time since diagnosis: 23.6 months, standard deviation [SD] 15.3; M.time since completing primary treatment: 14.7 months, SD 15.3) completed semistructured interviews. Questions related to dietary changes since diagnosis and treatment. Major themes were identified from interview transcripts using thematic analysis. Results: While most individuals perceived their diet to be broadly similar to prediagnosis, several changes to diet and eating habits were identified, which were often meaningful to these survivors. Themes relating to survivors' eating habit changes included the following: (1) meal timing and frequency shifts, (2) more plant-based eating, and (3) less variety and more convenience. Changes in eating habits were attributed to the following: (1) persisting treatment-related changes, (2) help and support from others, (3) old treatment habits, (4) preventative health and self-care, and (5) changes to work schedule. Barriers to making intentional dietary changes included the following: (1) too much time and effort, (2) food cravings and enjoyment, and (3) lacking dietary ideas and resources. Conclusions: Many survivors reported long-term changes in dietary habits, some of which align with current recommendations. Causes of dietary habit changes, and barriers to engaging in healthier dietary habits, involved multiple biopsychosocial elements. Additional resources or strategies that assist navigating survivorship challenges and their effects on dietary habits are needed. Future studies should explore whether post-treatment nutritional review with a qualified dietary health professional is helpful for survivors who experience long-term cancer-related cognitive impairment.
