ABSTRACT
OBJECTIVE: Experiences of menopause and quality of life during menopause can vary extensively among women. While menopause has been associated with negative impacts on eating and body image, it is unclear to what extent quality of life differs by eating disorder risk status. The aim of this study was to explore how menopause symptoms and quality of life differ between those women at high- or low-risk of an eating disorder and the potential protective role of body appreciation. METHOD: This cross-sectional survey study explored differences in menopausal quality of life, body appreciation, and body dissatisfaction among women classified as high- or low-risk of an eating disorder as part of a wider survey on aging, health, and psychological complaints during midlife. Participants were 255 females aged between 40 and 60 years. Participants were classified as high-risk and low-risk of an eating disorder based on Eating Attitudes Test-26 (EAT-26) scores. Differences between groups on the Menopause-Specific Quality of Life Questionnaire (MENQOL), Body Shape Questionnaire (BSQ-16), and Body Appreciation Scale-2 were analyzed. The predictive relationship between menopausal quality of life and body appreciation was also explored. RESULTS: Participants in the high-risk group (n = 111) reported significantly poorer menopausal quality of life compared to the low-risk group (n = 144), scoring significantly higher on the sexual, physical, and psychosocial subscales of the MENQOL. The high-risk group also had significantly greater body dissatisfaction and less body appreciation than the low-risk group. Overall, menopausal quality of life was a significant predictor of body appreciation. DISCUSSION: Women with greater eating disorder risk may be faring less well with menopause. Treating and preventing menopause-related eating disorders will benefit from interventions aimed at not only reducing body dissatisfaction, but actively bolstering body appreciation and supporting the sexual, physical, and psychosocial aspects of the menopausal transition.

Two of every three persons living with dementia reside in low- and middle-income countries (LMICs). The projected increase in global dementia rates is expected to affect LMICs disproportionately. However, the majority of global dementia care costs occur in high-income countries (HICs), with dementia research predominantly focusing on HICs. This imbalance necessitates LMIC-focused research to ensure that characterization of dementia accurately reflects the involvement and specificities of diverse populations. Development of effective preventive, diagnostic, and therapeutic approaches for dementia in LMICs requires targeted, personalized, and harmonized efforts. Our article represents timely discussions at the 2022 Symposium on Dementia and Brain Aging in LMICs that identified the foremost opportunities to advance dementia research, differential diagnosis, use of neuropsychometric tools, awareness, and treatment options. We highlight key topics discussed at the meeting and provide future recommendations to foster a more equitable landscape for dementia prevention, diagnosis, care, policy, and management in LMICs. HIGHLIGHTS: Two-thirds of persons with dementia live in LMICs, yet research and costs are skewed toward HICs. LMICs expect dementia prevalence to more than double, accompanied by socioeconomic disparities. The 2022 Symposium on Dementia in LMICs addressed advances in research, diagnosis, prevention, and policy. The Nairobi Declaration urges global action to enhance dementia outcomes in LMICs.

Introduction: With the number of menopausal women projected estimated to reach 1.2 billion by 2030 worldwide, it is critically important to understand how menopause may affect women's emotional well-being and how many women are affected by this. This study aimed to explore (i) the relationship between psychological complaints (depression, anxiety, poor memory) across different menopausal stages and (ii) investigate the correlation between resilience, self-efficacy, and perceived stress levels, with psychological complaints and whether this was associated with menopausal stage and/or age. Methods: 287 respondents completed the Menopausal Quality of Life (MenQoL), Perceived Stress Scale (PSS-10), Brief Resilience Scale (BRS), and General Self-efficacy (GSE) scales. Parametric and non-parametric analysis were used to analyse how bothered women were by self-reported poor memory and feelings of depression and anxiety, alongside perceived stress, resilience, and self-efficacy between women in different menopausal stages using STRAW criteria. The association between protective factors (self-efficacy and resilience) and psychological complaints was analysed with partial correlation analysis controlling for menopausal stages and/or age. Results: A significant difference was found between the levels of perceived stress, and how bothered women were by feelings of depression and anxiety between early-perimenopausal and post-menopausal women. However, with the inclusion of age as a covariate, menopausal stage no longer predicted the level of self-reported stress and anxiety in menopausal women. There was also no difference between poor self-reported memory, or of self-efficacy or resilience between women in different menopausal stages. However, self-efficacy and resilience were associated with how bothered women were by feelings of depression and anxiety, and the experience of stress. Stress was the only variable to be associated with poor self-reported memory independent of age and/or menopausal status. Discussion: Early perimenopausal women experienced the highest level of stress and were more severely bothered by feelings of depression and anxiety, with the poorest overall self-reported psychosocial quality of life. Post-menopausal women, however, reported to have similar experiences as premenopausal women. Age explained the associations between menopausal stage, stress and anxiety, but not between depression and different menopausal stages. Resilience and self-efficacy were associated with psychological complaints independent of menopausal stage and age, suggesting that therapies focusing on increasing resilience and self-efficacy may be beneficial to help target these psychological complaints at any time.
ABSTRACT
Visual processing deficits have frequently been reported when studied in individuals with dementia, which suggests their potential utility in supporting dementia screening. The study uses EPIC-Norfolk Prospective Population Cohort Study data (n = 8623) to investigate the role of visual processing speed assessed by the Visual Sensitivity Test (VST) in identifying the risk of future dementia using Cox regression analyses. Individuals with lower scores on the simple and complex VST had a higher probability of a future dementia diagnosis HR1.39 (95% CI 1.12, 1.67, P < 0.01) and HR 1.56 (95% CI 1.27, 1.90, P < 0.01), respectively. Although other more commonly used cognitive dementia screening tests were better predictors of future dementia risk (HR 3.45 for HVLT and HR 2.66, for SF-EMSE), the complex VST showed greater sensitivity to variables frequently associated with dementia risk. Reduced complex visual processing speed is significantly associated with a high likelihood of a future dementia diagnosis and risk/protective factors in this cohort. Combining visual processing tests with other neuropsychological tests could improve the identification of future dementia risk.

PURPOSE: The primary aim of this study was to examine whether a glycine-rich collagen peptides (CP) supplement could enhance sleep quality in physically active men with self-reported sleep complaints. METHODS: In a randomized, crossover design, 13 athletic males (age: 24 ± 4 years; training volume; 7 ± 3 h·wk1) with sleep complaints (Athens Insomnia Scale, 9 ± 2) consumed CP (15 g·day1) or a placebo control (CON) 1 h before bedtime for 7 nights. Sleep quality was measured with subjective sleep diaries and actigraphy for 7 nights; polysomnographic sleep and core temperature were recorded on night 7. Cognition, inflammation, and endocrine function were measured on night 7 and the following morning. Subjective sleepiness and fatigue were measured on all 7 nights. The intervention trials were separated by ≥ 7 days and preceded by a 7-night familiarisation trial. RESULTS: Polysomnography showed less awakenings with CP than CON (21.3 ± 9.7 vs. 29.3 ± 13.8 counts, respectively; P = 0.028). The 7-day average for subjective awakenings were less with CP vs. CON (1.3 ± 1.5 vs. 1.9 ± 0.6 counts, respectively; P = 0.023). The proportion of correct responses on the baseline Stroop cognitive test were higher with CP than CON (1.00 ± 0.00 vs. 0.97 ± 0.05 AU, respectively; P = 0.009) the morning after night 7. There were no trial differences in core temperature, endocrine function, inflammation, subjective sleepiness, fatigue and sleep quality, or other measures of cognitive function or sleep (P > 0.05). CONCLUSION: CP supplementation did not influence sleep quantity, latency, or efficiency, but reduced awakenings and improved cognitive function in physically active males with sleep complaints.

OBJECTIVES: Growing epidemiological evidence has shown hearing loss is associated with physical inactivity. Currently, there is a dearth in evidence investigating why this occurs. This study aimed to investigate the barriers and facilitators to physical activity in middle-aged and older adults with hearing loss. DESIGN: Individual semi-structured qualitative interviews. METHODS: A phenomenological approach was taken. Ten adults (≥40 years) were interviewed via videoconferencing. The interview schedule was underpinned by the capability, opportunity, motivation and behaviour (COM-B) model. Reflexive thematic analysis was used to generate themes, which were subsequently mapped onto the COM-B model and behaviour change wheel. RESULTS: Nine hearing loss specific themes were generated, which included the following barriers to physical activity: mental fatigue, interaction with the environment (acoustically challenging environments, difficulties with hearing aids when physically active) and social interactions (perceived stigma). Environmental modifications (digital capabilities of hearing aids), social support (hearing loss-only groups) and hearing loss self-efficacy were reported to facilitate physical activity. CONCLUSIONS: Middle-aged and older adults with hearing loss experience hearing-specific barriers to physical activity, which has a deleterious impact on their overall health and well-being. Interventions and public health programmes need to be tailored to account for these additional barriers. Further research is necessary to test potential behaviour change techniques.

BACKGROUND: We investigated the effect of subclinical hyperthyroidism and subclinical hypothyroidism on cognitive function in rats and the role of autophagy in this process. METHODS: Forty Wistar rats were randomized into normal control (NC), hyperthyroidism (Hyper), hypothyroidism (Hypo), subclinical hyperthyroidism (sHyper), and subclinical hypothyroidism (sHypo) groups. Cognitive function (spatial learning and memory) was tested by the Morris water maze test. Hippocampal histopathology was analyzed by H&E staining, and expression levels of caspase-3 in hippocampal CA1 neurons were measured. In addition, immunoblot analysis was performed to detect hippocampal autophagy-related proteins. RESULTS: Escape latency from day 1 to day 4 was significantly longer in the Hypo, Hyper, and sHyper groups than in the NC group (P < 0.01). In addition, the number of rats crossing the virtual platform was significantly lower in the Hypo, Hyper, and sHyper groups than in the NC group (P < 0.01). Compared with the NC group, all four groups had significantly lower residence time in the target quadrant (P < 0.05). Beclin-1 and LC3-II protein expression in hippocampal tissues was significantly higher in the Hyper and sHyper groups than in the NC group (P < 0.01). Beclin-1 and LC3-II protein expression in hippocampal tissues did not significantly differ between the sHypo group and NC group (P > 0.05). CONCLUSIONS: Subclinical thyroid dysfunction in rats might lead to cognitive impairment. Subclinical hyperthyroidism might be associated with excessive activation of autophagy and hippocampal neuron damage and necrosis.

Background and Objectives: The effectiveness of exergames on fall risk and related physical and cognitive function in older adults is still unclear, with conflicting findings. The discrepancy in these results could be due to the different components and task-specific demands of individual exergame interventions. This open-label quasi-randomized study aimed to compare the efficacy of 2 different home-based dual-task exergame treatments on cognition, mobility, and balance in older people. Research Design and Methods: Fifty older adults (65-85 years of age) were allocated to one of two 8-week exergame interventions: Cognitive-Intensive Exergame Training (CIT) or Physical-Intensive Exergame Training (PIT). Cognitive functions, balance, and mobility were assessed at baseline and after 8 weeks. Groupâ ×â time interaction was measured by repeated-measure ANOVA, and both intention-to-treat (ITT) and per-protocol (PP) analyses were performed to assess the effectiveness of exergame interventions. Results: ITT analyses showed that improvement in visual processing speed and visuospatial working memory was greater in the CIT group, with a medium effect size (pâ =â .04; η2â =â 0.09 and pâ =â .01; η2â =â 0.12). The improvement in verbal memory and attention was significant within both groups (pâ <â .05), but this improvement was not different between the groups (pâ >â .05). A significant improvement in balance was also observed in the PIT group, with a medium effect size (pâ =â .04; η2â =â 0.09). Although mobility improved significantly in both groups (pâ <â .01), there was no significant difference between groups (pâ =â .08). These results were largely supported by the PP analysis. Discussion and Implications: Dual-task exergame training can improve mobility and cognition in older adults. However, the different cognitive and physical demands of these interventions may have varying impacts on fall risk and related physical or cognitive functions. Therefore, a training program that includes both cognitive and physical domains with appropriate intensity is essential for the development of tailored exergame interventions to reduce fall risk in older adults.
ABSTRACT
Importance: Although professional soccer players appear to be at higher risk of neurodegenerative disease, the reason remains unknown. Objective: To examine whether heading frequency is associated with risk of cognitive impairment in retired professional soccer players. Design, Setting, and Participants: A UK nationwide cross-sectional study was conducted between August 15, 2020, and December 31, 2021, in 459 retired male professional soccer players older than 45 years and registered with the Professional Footballers' Association or a League Club Players' Association. Exposure: Data on heading frequency in 3 bands-0 to 5, 6 to 15, and more than 15 times per match or training session and other soccer-specific risk factors, such as player position and concussion-were collected through a self-reported questionnaire. Main Outcomes and Measures: Cognitive impairment was defined using the Telephone Interview for Cognitive Status-modified as scores of less than or equal to 21. Hopkins Verbal Learning Test, verbal fluency, and independent activities of daily living were also assessed. Test Your Memory and physician-diagnosed dementia/Alzheimer disease were self-reported via the questionnaire. Adjusted odds ratios (AORs) with 95% CIs were calculated. Results: Of 468 retired male professional soccer players who completed questionnaires (mean [SD] age, 63.68 [10.48]; body mass index, 27.22 [2.89]), 459 reported heading frequency: 114 headed 0 to 5 times, 185 headed 6 to 15 times, 160 headed more than 15 times per match, and 125 headed 0 to 5 times, 174 headed 6 to 15 times, and 160 headed more than 15 times per training session during their careers. The prevalence of cognitive impairment was 9.78% (0-5 times), 14.78% (6-15 times), and 15.20% (>15 times) per match (P = .51). Compared with players reporting 0 to 5 headers per match, the AORs were 2.71 (95% CI, 0.89-8.25) for players reporting 6 to 15 headers per match and 3.53 (95% CI, 1.13-11.04) for players reporting more than 15 headers per match (P = .03 for trend). Corresponding AORs for heading frequency per training session were 2.38 (95% CI, 0.82-6.95) for those reporting 6 to 15, and 3.40 (95% CI, 1.13-10.23) for those reporting more than 15 in comparison with those who reported 0 to 5 (P = .03 for trend). Concussion involving memory loss was also associated with a greater risk of cognitive impairment (AOR, 3.16; 95% CI, 1.08-9.22). Similar results were observed with other cognitive tests and self-reported physician-diagnosed dementia/Alzheimer disease. Conclusions and Relevance: The findings of this study suggest that repetitive heading during a professional soccer career is associated with an increased risk of cognitive impairment in later life. Further study is needed to establish the upper threshold for heading frequency to mitigate this risk.

Although cross-sectional studies suggest that hearing loss in middle- and older-aged adults is associated with lower physical activity, longitudinal evidence is limited. This study aimed to investigate the potential bi-directional association between hearing loss and physical activity over time. Participants were from the English Longitudinal Study of Ageing (N = 11,292) who were 50-years or older at baseline assessment (1998-2000). Individuals were followed-up biannually for up to 20-years (2018-2019) and were classified as ever reporting hearing loss (n = 4946) or not reporting hearing loss (n = 6346). Data were analysed with Cox-proportional hazard ratios and multilevel logistic regression. The results showed that baseline physical activity was not associated with hearing loss over the follow-up. Time (i.e., wave of assessment) by hearing loss interactions showed that physical activity declined more rapidly over time in those with hearing loss, compared to those without (Odds Ratios = 0.94, 95% Confidence Intervals; 0.92-0.96, p < .001). These findings highlight the importance of addressing physical activity in middle- and older-aged adults with hearing loss. As physical activity is a modifiable behaviour that can reduce the risk of developing chronic health conditions, individuals with hearing loss may need additional, tailored support to be more physically active. Mitigating the decline in physical activity could be essential to support healthy ageing for adults with hearing loss.

BACKGROUND: Previous studies based on death certificates have found professional soccer players were more likely to die with neurodegenerative diseases, including dementia. Therefore, this study aimed to investigate whether retired professional male soccer players would perform worse on cognitive tests and be more likely to self-report dementia diagnosis than general population control men. METHODS: A cross-sectional comparative study was conducted between August 2020 and October 2021 in the United Kingdom (UK). Professional soccer players were recruited through different soccer clubs in England, and general population control men were recruited from the East Midlands in the UK. We obtained self-reported postal questionnaire data on dementia and other neurodegenerative diseases, comorbidities and risk factors from 468 soccer players and 619 general population controls. Of these, 326 soccer players and 395 general population controls underwent telephone assessment for cognitive function. RESULTS: Retired soccer players were approximately twice as likely to score below established dementia screening cut-off scores on the Hopkins Verbal Learning Test (OR 2.06, 95%CI 1.11-3.83) and Verbal Fluency (OR 1.78, 95% CI 1.18-2.68), but not the Test Your Memory, modified Telephone Interview for Cognitive Status, and Instrumental Activities of Daily Living. Analyses were adjusted for age, education, hearing loss, body mass index, stroke, circulatory problems in the legs and concussion. While retired soccer players were younger, had fewer cardiovascular diseases and other morbidities and reported healthier lifestyles, 2.8% of retired soccer players reported medically diagnosed dementia and other neurodegenerative disease compared to 0.9% of controls (OR = 3.46, 95% CI 1.25-9.63) after adjustment for age and possible confounders. CONCLUSIONS: UK male retired soccer players had a higher risk of performing below established cut-off scores of dementia screening tests and were more likely to self-report medically diagnosed dementia and neurodegenerative diseases, despite having better overall physical health and fewer dementia risk factors. Further study is needed to determine specific soccer-related risk factors.
ABSTRACT
OBJECTIVE: To investigate whether the association between hearing difficulties and self-reported memory problems is mediated by physical health and psychosocial wellbeing. DESIGN: A cross-sectional study. Path analyses were used to test potential theoretical models (psychosocial-cascade, common cause) of the association between hearing difficulties and memory problems, adjusting for age. STUDY SAMPLE: A sample of 479 adults (18-87 years) completed self-reported outcome measures. RESULTS: Half the participants reported clinically significant hearing difficulties and 30% self-reported memory problems. In the direct model, reporting hearing difficulties was associated with a greater likelihood of reporting memory problems (ß = 0.17, p = 0.007, 95% Confidence Intervals [CI] = 0.00, 0.01). Hearing difficulties were also associated with poorer physical health, but this did not mediate the association with memory. Psychosocial factors, however, fully mediated the relationship between hearing difficulties and memory problems (ß = 0.03, p = 0.019, 95% CI = 0.00, 0.01). CONCLUSIONS: Adults with hearing difficulties may be more likely to self-report memory problems, irrespective of age. This study supports the psychosocial-cascade model, as the association between self-reported hearing and memory problems was explained entirely by psychosocial factors. Future studies should investigate these associations using behavioural measures, as well as explore whether interventions can reduce the risk of developing memory problems in this population.
ABSTRACT
AIMS: This study aimed to evaluate the association between memory impairment and its risk and protective factors, focusing on demographic and health-related variables among older adults in Indonesia. METHOD: The data analyzed were the Indonesian Family Life Survey-5 (IFLS-5) using cross-sectional variables of 4236 older adults aged 60 years and over included in the 2015 round. Memory impairment was assessed by immediate word list recall from the Telephone Interview for Cognitive Status (TICS). Sociodemographic factors and multiple health variables were included as predictors. Data were analyzed using frequency analyses bivariate and stepwise logistic regression tests. RESULT: Among 4236 older adults, 49.7% were male and 50.3% were female. Stepwise backward analyses showed that memory impairment was independently associated with older age, being female, or not in a union (unmarried, separated, divorced, or widowed), having obtained low levels of education, living in a rural area, reporting low life satisfaction, low social capital, higher dependency, and having clinical depression. Only moderate (but not high or low) physical activity levels were associated with a lower risk. Being underweight increased the risk, but being overweight/obese (as assessed by BMI) protective factors for a lower immediate recall score. CONCLUSION: Increasing education and continued engagement of older adults in psychosocial activities, including moderate physical activity, improving mental health, preventing weight loss, and maintaining functional ability to decrease dependency, are associated with increased episodic memory, especially in non-married and older women in rural areas of Indonesia.
ABSTRACT
Human beings lead largely sedentary lives. From an evolutionary perspective, such lifestyle is not beneficial to health. Exercise can promote many enabling pathways, particularly through circulating exerkines, to optimize individual health and quality of life. Such benefits might explain the protective effects of exercise against aging and noncommunicable diseases. Nevertheless, the miRNA-mediated molecular mechanisms and exerkine interorgan crosstalk that underlie the beneficial effects of exercise remain poorly understood. In this mini review, we focused on the exerkine, irisin, mainly produced by muscle contraction during adaptation to exercise and its beneficial effects on body homeostasis. Herein, the complex role of irisin in metabolism and inflammation is described, including its subsequent effects on thermogenesis through browning to control obesity and improve glycemic regulation for diabetes mellitus control, its potential to improve cognitive function (via brain derived neurotrophic factor), and its pathways of action and role in aging.

BackgroundWomen in many cohorts have a higher risk for Alzheimer's disease (AD), the most common form of dementia. Sex is a biological construct whereby differences in disease manifestation and prevalence are rooted in genetic differences between XX and XY combinations of chromosomes. This chapter focuses specifically on sex-driven differences in dementia, as opposed to differences driven by gender - a social construct referring to the societal norms that influence people's roles, relationships, and positional power throughout their lifetime.MethodsUsing a narrative review, this chapter explored the characteristics and risk factors for the dementias, alongside a discussion of sex differences including loss of sex steroid hormones in middle-aged women, differences in the prevalence of cardiovascular diseases and engagement in lifestyle protective factors for dementia.ResultsThe sex difference in AD prevalence may exist because of systematic and historic differences in risk and protective factors for dementia, including level of education obtained and socioeconomic status differences, which can impact on health and dementia risk.Levels of sex steroids decline significantly after menopause in women, whereas this is more gradual in men with age. Animal and cell culture studies show strong biological plausibility for sex steroids to protect the ageing brain against dementia. Sex steroid hormone replacement therapy has in some observational studies shown to protect against AD, but treatment studies in humans have mainly shown disappointing results. Cardiovascular disease (CVD) shares midlife medical risk (e.g. hypertension, hyperlipidaemia, obesity etc.) factors with AD and other forms of dementia, but also with related lifestyle risk - and protective factors (e.g. exercise, not smoking etc.). Men tend to die earlier of CVD, so fewer survive to develop AD at an older age. Those who do survive may have healthier lifestyles and fewer risk factors for both CVD and AD. An earlier age at menopause also confers great risk for both without hormone treatment.DiscussionIt could be the case that the decline in sex steroids around the menopause make women more susceptible to lifestyle-related risk factors associated with dementia and CVD, but this remains to be further investigated. Combining hormone treatment with lifestyle changes in midlife (e.g. exercise) could be an important preventative treatment for dementia and CVD in later life, but this also requires further research.

INTRODUCTION: Recent evidence suggests that there is clear association between microbiota and cognitive functioning, which is known as microbiome-gut-brain axis. Probiotic bacteria consumption can alter human microbiota; therefore, probiotic supplementation might affect the gut microbiota dynamics and influence cognitive function. METHODS: Three electronic databases including PubMed, ProQuest, and EBSCOHost databases were utilized. Manual hand search of article was also done. We selected randomized controlled trial articles that measure cognitive function (as the primary outcome) after intervention with probiotic supplementation on older adult population with AD, MCI, or healthy condition. The following terms and its variant were used: "probiotic," "cognitive function," "mild cognitive impairment," "dementia," and "Alzheimer's disease." RESULT: Nine of 10 included studies (AD, MCI, or healthy cognition population) showed cognitive function was improved significantly after probiotic supplementation, compared to control group. One study that included severe AD did not show significant changes. CONCLUSION: Most studies involving AD, MCI, or healthy older adults showed cognitive improvement in subjects treated with probiotics for 12-24 weeks.

INTRODUCTION: Professional footballers commonly experience sports-related injury and repetitive microtrauma to the foot and ankle, placing them at risk of subsequent chronic pain and osteoarthritis (OA) of the foot and ankle. Similarly, repeated heading of the ball, head/neck injuries and concussion have been implicated in later development of neurodegenerative diseases such as dementia. A recent retrospective study found that death from neurodegenerative diseases was higher among former professional soccer players compared with age matched controls. However, well-designed lifetime studies are still needed to provide evidence regarding the prevalence of these conditions and their associated risk factors in retired professional football players compared with the general male population. OBJECTIVES: To determine whether former professional male footballers have a higher prevalence than the general male population of: (1) foot/ankle pain and radiographic OA; and (2) cognitive and motor impairments associated with dementia and Parkinson's disease. Secondary objectives are to identify specific football-related risk factors such as head impact/concussion for neurodegenerative conditions and foot/ankle injuries for chronic foot/ankle pain and OA. METHODS AND ANALYSIS: This is a cross-sectional, comparative study involving a questionnaire survey with subsamples of responders being assessed for cognitive function by telephone assessment, and foot/ankle OA by radiographic examination. A sample of 900 adult, male, ex professional footballers will be recruited and compared with a control group of 1100 age-matched general population men between 40 and 100 years old. Prevalence will be estimated per group. Poisson regression will be performed to determine prevalence ratio between the populations and logistic regression will be used to examine risk factors associated with each condition in footballers. ETHICS AND DISSEMINATION: This study was approved by the East Midlands-Leicester Central Research Ethics Committee on 23 January 2020 (REC ref: 19/EM/0354). The study results will be disseminated at national and international meetings and submitted for peer-review publication.

PURPOSE: The purpose of this study was to investigate the extent to which validated online screening measures of cognitive impairment, psychosocial well-being, and cardiovascular health are associated with a validated hearing screener in a sample of adults based in the United Kingdom. METHOD: Sixty-one adults (43 female; M age = 44.7 years) participated in a cross-sectional study delivered remotely. Participants completed the hearWHO smartphone application, a digits-in-noise hearing screener, and the Modified Telephone Interview for Cognitive Status (TICS-M), a screening tool for cognitive impairment. Psychosocial well-being (social isolation and loneliness) and cardiovascular health were assessed through self-report. RESULTS: Separate independent analyses of variance, with age, gender, and education as covariates, demonstrated participants who failed the hearWHO screener had poorer scores on the TICS-M, engaged in less physical activity, and reported more sedentary behavior and greater social isolation. Multivariate regression analyses revealed that lower TICS-M scores, having obtained less education, identifying as female, and reporting greater sedentary behavior and social isolation were the strongest predictors of lower hearWHO scores. CONCLUSIONS: The results from this study suggest that poorer hearing, as measured by the hearWHO screener, is independently associated with having worse cognitive function, more time spent being sedentary, and greater social isolation. Thus, this study demonstrates the potential of online screening measures to identify additional health conditions that confer risk to chronic disease as hearing loss manifests. This could help to inform the development of tailored treatment and support to improve an individual's readiness to seek help for and manage both their general and hearing health.
