Relationships between oxidative balance score and asthma, COPD, with asthma-COPD overlap in American adults: findings from NHANES 2013–2018

Background Oxidative stress plays a crucial role in the development of multiple chronic respiratory diseases. Oxidative Balance Score (OBS) composing of 16 dietary factors and 4 lifestyle factors has been developed to evaluate the effect of oxidants/antioxidants produced by dietary intake and lifestyle habits on the overall oxidative balance. However, the relationships between OBS with asthma, COPD, and asthma-COPD overlap (ACO) are still unclear. Methods A total of 10,942 adults aged 20 years and older from the 2013–2018 National Health and Nutrition Examination Survey were included in the analyses. ANOVA and chi-square tests were used to compare characteristics between different OBS subgroups. Multiple multivariate logistic regression was used to analyze the associations between OBS and asthma, COPD, and ACO.RCS curves were used to describe the dose-response effect of the associations. Subgroup analyses and interaction effects were employed to reflect the stability of the associations. Results In the fully adjusted models, OBS was found to be negatively associated with asthma, COPD, and ACO. OBS at Q2, Q3, and Q4 (OR: 0.66, 95% CI: 0.46–0.97) were negatively associated with the risk of asthma. OBS at Q2 and Q4 were negatively associated with the risk of COPD. OBS at Q2 and Q4 were negatively associated with the risk of ACO. The RCS curves reflected the negative dose-response trend of association. Moreover, the associations were stable in various subgroups. Conclusion The negative associations between OBS and asthma, COPD, and ACO were found in American adults, providing evidence for dietary and lifestyle prevention.

Evolving trends in oral cancer burden in Europe: a systematic review.

Oral cavity cancer (OCC), primarily oral squamous cell carcinoma (OSCC), is a growing concern in Europe, particularly among younger populations. Preventable lifestyle factors and social determinants of health contribute significantly to the disease burden. Limited access to healthcare and delayed diagnoses further complicate treatment and reduce survival rates. This systematic literature review adhered to PRISMA guidelines to explore trends in OSCC epidemiology, etiology, diagnosis, treatment, and survival across Europe. A comprehensive search strategy using PubMed, GLOBOCAN data, and the EUROCARE-5 study identified relevant articles focusing on human populations in Europe with a primary interest in OSCC epidemiology. Only peer-reviewed publications in English with full-text access were included. This study investigated the burden of OSCC across Europe, revealing variations in incidence, mortality, and prognosis. Eastern and Central Europe displayed the highest burden. Males exhibited a significantly higher risk compared to females. Age-related disparities existed in life expectancy and time to achieve favorable outcomes. HPV emerged as a growing risk factor for oropharyngeal cancer. Public health strategies should target modifiable risk factors and improve early detection. This review reveals concerning disparities in European OSCC. Region, sex, and age all influence burden and prognosis. Future research should focus on controlling risk factors and personalized medicine to optimize treatment. This will lead to a Europe with reduced OSCC incidence and demonstrably better patient outcomes.

The state of knowledge: This review examines the epidemiology, pathophysiology, and risk factors associated with ED, emphasizing the importance of lifestyle in prevention and treatment. The role of diet, physical activity, weight reduction, smoking cessation, and alcohol restriction in improving erectile function is discussed. The article also presents current diagnostic and therapeutic approaches, including pharmacotherapy, alternative therapies and psychological interventions. Conclusions: Erectile dysfunction (ED) is a complex health issue that necessitates a comprehensive and interdisciplinary diagnostic and therapeutic approach. Lifestyle plays a pivotal role in the prevention and treatment of ED, and its modification should be an integral component of any treatment plan.

Training program focused on tasks aimed at promoting sustainable balance management in elderly individuals

Background: physical performance deteriorates over the years, due to the disuse of the musculoskeletal system, predisposing to balance and gait problems. During the development of the research the priority attention group-elderly population. Objective: to implement physical activity, prevention of sedentary lifestyle, through exercise it was possible to improve balance with the implementation of a double and simple task exercise program due to the consequences generated by dependence in older adults regarding physical, psychological and social health, in which older adults have been found to lose their independence. Methods: the research was descriptive based on the qualitative, cross-sectional approach in which an initial and final evaluation of the Tinetti test was performed, then the exercise program was executed for 16 weeks, lasting 10 to 45 minutes for each exercise. Results: there was a predominance of 63.3% to the female gender and 36.7% male gender, with the significant verification ap value of (p>0.039) was obtained in the test; being less than alpha (p<0.05) rejecting the null hypothesis. Conclusions: the double and simple task exercise program was systematically applied to the entire sample population, which through its intervention is concluded to give the expected results verified with the Initial and Final Tinetti Test there is a finding of great importance improving balance and avoiding the risk of falls in older adults.

Navigating the Depths of Cardiovascular Effects on Submariners.

The environment of the submariner is inherently endowed with several health risk factors, namely confinement, inactivity, caloric excess, and circadian disruption, among others, during deployment. Metabolic disturbances, increased cardiovascular risk, and sleep deprivation are associated with interrupting circadian rhythms due to routines contributing to physiological and cognitive abnormalities. Additionally, submariners face vitamin deficits of vitamin D and vitamin B12 due to little exposure to sunlight and poor nutrition. It is associated with cardiovascular dysfunctions, endothelial dysfunctions, metabolic abnormalities, and a greater cardiovascular risk. Moreover, high obesity prevalence has been noted among submariners. Such cases were attributed to leptin resistance, body fat deposits, and lifestyle statistics. Other risk factors to the cardiovascular system, like changes in heart rate variability and heart functions, have been witnessed. These health challenges can be mitigated by adopting proactive steps to address submariners' specific health needs. Such measures should include the prevention of stable circadian rhythms, vitamin intake, lifestyle, and cardiovascular health. By addressing these issues, submariners' well-being will be upheld, and their vulnerability to cardiovascular diseases and other health-related complications will be lessened.

Multicomponent Support Program for Secondary Prevention of Stroke Using Digital Health Technology: Co-Design Study With People Living With Stroke or Transient Ischemic Attack.

Few individuals (<2%) who experience a stroke or transient ischemic attack (TIA) participate in secondary prevention lifestyle programs. Novel approaches that leverage digital health technology may provide a viable alternative to traditional interventions that support secondary prevention in people living with stroke or TIA. To be successful, these strategies should focus on user needs and preferences and be acceptable to clinicians and people living with stroke or TIA. This study aims to co-design, with people with lived experience of stroke or TIA (referred to as consumers) and clinicians, a multicomponent digital technology support program for secondary prevention of stroke. A consumer user needs survey (108 items) was distributed through the Australian Stroke Clinical Registry and the Stroke Association of Victoria. An invitation to a user needs survey (135 items) for clinicians was circulated via web-based professional forums and national organizations (eg, the Stroke Telehealth Community of Practice Microsoft Teams Channel) and the authors' research networks using Twitter (subsequently rebranded X, X Corp) and LinkedIn (LinkedIn Corp). Following the surveys, 2 rounds of user experience workshops (design and usability testing workshops) were completed with representatives from each end user group (consumers and clinicians). Feedback gathered after each round informed the final design of the digital health program. Overall, 112 consumers (male individuals: n=63, 56.3%) and 54 clinicians (female individuals: n=43, 80%) responded to the survey; all items were completed by 75.8% (n=85) of consumers and 78% (n=42) of clinicians. Most clinicians (46/49, 94%) indicated the importance of monitoring health and lifestyle measures more frequently than current practice, particularly physical activity, weight, and sleep. Most consumers (87/96, 90%) and clinicians (41/49, 84%) agreed that providing alerts about potential deterioration in an individual's condition were important functions for a digital program. Intention to use a digital program for stroke prevention and discussing the data collected during face-to-face consultations was high (consumers: 79/99, 80%; clinicians 36/42, 86%). In addition, 7 consumers (male individuals: n=5, 71%) and 9 clinicians (female individuals: n=6, 67%) took part in the user experience workshops. Participants endorsed using a digital health program to help consumers manage stroke or TIA and discussed preferred functions and health measures in a digital solution for secondary prevention of stroke. They also noted the need for a mobile app that is easy to use. Clinician feedback highlighted the need for a customizable clinician portal that captures individual consumer goals. Following an iterative co-design process, supported by evidence from user needs surveys and user experience workshops, a consumer-facing app that integrates wearable activity trackers and a clinician web portal were designed and developed to support secondary prevention of stroke. Feasibility testing is currently in progress to assess acceptability and use.

Diet and Physical Activity Interventions for People from Minority Ethnic Backgrounds in the UK: A Scoping Review Exploring Barriers, Enablers and Cultural Adaptations.

Type 2 diabetes (T2D) and cardiovascular disease (CVD) are a global pandemic, driven by obesity, poor diet and physical inactivity. In the UK, the prevalence of T2D and CVD is higher in minority ethnic groups. Lifestyle prevention interventions can be effective but uptake amongst minority ethnic groups in the UK is low and the extent of cultural adaptations to increase engagement unknown. To explore barriers, enablers and culturally adapted lifestyle interventions in UK minority ethnic groups. Four electronic databases were searched from to January 2013-2023. Two independent reviewers carried out manuscript selection and data extraction. Barriers and enablers were mapped to the Capability + Opportunity + Motivation = Behaviour (COM-B) theoretical model. Intervention adaptations were linked to behaviour change strategies and reported within a Cultural Adaptation framework. Twenty-three studies were included, reporting barriers/enablers, culturally adapted interventions or both. Barriers and enablers mostly mapped to social and physical opportunity, and reflective motivation. Common adaptation strategies considered behavioural influences related to culture, values, religious beliefs and/or traditions. Most impactful strategies were associated with using credible sources of information and reorganising social and environmental contexts. The current umbrella approach to preventative intervention delivery is unlikely to promote sustained participation in behaviour change amongst UK ethnic minorities. Engagement strategies for this population should consider key determinants such as social contexts, beliefs and cultural norms. Important research gaps include interventions investigating tailored interventions for Black populations, and the impact of negative social experiences (e.g., racism) on engagement.

The Prevention of Childhood Obesity Is a Priority: The Preliminary Results of the "EpPOI: Education to Prevent Childhood Obesity" Project.

The increase in childhood obesity rates represents a serious public health problem. The project "EpPOI: Education to prevent childhood obesity" is aimed at a multidisciplinary approach to raise awareness of the importance of preventing childhood obesity through lifestyle education. Two actions by experts were performed: an intervention with children in schools and a meeting for both parents and school staff. Participants completed a questionnaire structured as a Likert scale. The sample size was 96 people, and awareness of the childhood obesity problem as well as the need for obesity prevention was high among respondents. We also found great interest among participants in having more information on pediatric nutrition and physical activity, with a positive correlation with age. Furthermore, the multivariate regression model configured interest in having more information on nutrition and physical activity as an independent and statistically significant predictor of awareness of childhood obesity as a current issue. The results highlight the need to act on childhood obesity through lifestyle prevention strategies early in life.

Characterizing Technology Use and Preferences for Health Communication in South Asian Immigrants With Prediabetes or Diabetes: Cross-Sectional Descriptive Study.

Type 2 diabetes disproportionately affects South Asian subgroups. Lifestyle prevention programs help prevent and manage diabetes; however, there is a need to tailor these programs for mobile health (mHealth). This study examined technology access, current use, and preferences for health communication among South Asian immigrants diagnosed with or at risk for diabetes, overall and by sex. We examined factors associated with interest in receiving diabetes information by (1) text message, (2) online (videos, voice notes, online forums), and (3) none or skipped, adjusting for sociodemographic characteristics and technology access. We used baseline data collected in 2019-2021 from two clinical trials among South Asian immigrants in New York City (NYC), with one trial focused on diabetes prevention and the other focused on diabetes management. Descriptive statistics were used to examine overall and sex-stratified impacts of sociodemographics on technology use. Overall logistic regression was used to examine the preference for diabetes information by text message, online (videos, voice notes, or forums), and no interest/skipped response. The overall sample (N=816) had a mean age of 51.8 years (SD 11.0), and was mostly female (462/816, 56.6%), married (756/816, 92.6%), with below high school education (476/816, 58.3%) and limited English proficiency (731/816, 89.6%). Most participants had a smartphone (611/816, 74.9%) and reported interest in receiving diabetes information via text message (609/816, 74.6%). Compared to male participants, female participants were significantly less likely to own smartphones (317/462, 68.6% vs 294/354, 83.1%) or use social media apps (Viber: 102/462, 22.1% vs 111/354, 31.4%; WhatsApp: 279/462, 60.4% vs 255/354, 72.0%; Facebook: Messenger 72/462, 15.6% vs 150/354, 42.4%). A preference for receiving diabetes information via text messaging was associated with male sex (adjusted odds ratio [AOR] 1.63, 95% CI 1.01-2.55; P=.04), current unemployment (AOR 1.62, 95% CI 1.03-2.53; P=.04), above high school education (AOR 2.17, 95% CI 1.41-3.32; P<.001), and owning a smart device (AOR 3.35, 95% CI 2.17-5.18; P<.001). A preference for videos, voice notes, or online forums was associated with male sex (AOR 2.38, 95% CI 1.59-3.57; P<.001) and ownership of a smart device (AOR 5.19, 95% CI 2.83-9.51; P<.001). No interest/skipping the question was associated with female sex (AOR 2.66, 95% CI 1.55-4.56; P<.001), high school education or below (AOR 2.02, 95% CI 1.22-3.36; P=.01), not being married (AOR 2.26, 95% CI 1.13-4.52; P=.02), current employment (AOR 1.96, 95% CI 1.18-3.29; P=.01), and not owning a smart device (AOR 2.06, 95% CI 2.06-5.44; P<.001). Technology access and social media usage were moderately high in primarily low-income South Asian immigrants in NYC with prediabetes or diabetes. Sex, education, marital status, and employment were associated with interest in mHealth interventions. Additional support to South Asian women may be required when designing and developing mHealth interventions.

Joint association and interaction of birth weight and lifestyle with hypertension: A cohort study in UK Biobank.

Low birth weight and unhealthy lifestyle are both associated with an increased risk of hypertension. The authors aimed to assess the joint association and interaction of birth weight and lifestyle with incident hypertension. The authors included 205522 participants free of hypertension at baseline from UK Biobank. A healthy lifestyle score was constructed using information on body mass index, physical activity, diet, smoking status and alcohol intake. Cox proportional hazard models were used to investigate the impact of birth weight, healthy lifestyle score and their joint effect on hypertension. The authors documented 13548 (6.59%) incident hypertension cases during a median of 8.6years of follow-up. The multivariate adjusted hazard ratios and 95% confidence intervals were 1.12 (1.09, 1.15) per kg lower birth weight and 0.76 (0.75, 0.77) per score increment in healthy lifestyle score. Healthy lifestyle reduced the risk of hypertension in any category of different birth weight groups. The preventive effect of healthy lifestyle on hypertension was the most pronounced at lower birth weight with <2500g and 2500-2999g, respectively. Addictive interaction between birth weight and healthy lifestyle score was observed with the relative excess risk due to interaction of 0.04 (0.03, 0.05). Our findings emphasized the importance of healthy lifestyle for hypertension prevention, especially among the high-risk population with lower birth weight.

Association of fish and meat consumption with non-alcoholic fatty liver disease: Guangzhou Biobank Cohort Study

BackgroundNon-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease. Unhealthy dietary habit is one of major risk factors of NAFLD. However, the associations between specific types of fish and meat consumption and NAFLD remain inconclusive. We explored the associations of fish and meat consumption with NAFLD risk in middle-aged and older Chinese.MethodsWe collected information on 1,862 participants aged 50 years or older from Guangzhou Biobank Cohort Study in 2009 to 2010. Fish and meat consumption was assessed using a validated food-frequency questionnaire. NAFLD was diagnosed by ultrasound. Multivariable logistic regression was used to examine the associations of fish and meat consumption with the presence of NAFLD.ResultsThe average age was 61.0 (standard deviation = 6.5) years for the participants, 50.2% were women, and 37.2% were diagnosed with NAFLD. After adjusting for age, sex, education, family income, occupation, smoking status, drinking status, physical activity and several metabolic traits, compared with 0 serving/week (one serving = 50 g), fatty fish consumption of ≥ 3 servings/week showed higher odds of NAFLD (odds ratio (OR) and 95% confidence interval (CI): 1.64 (1.12, 2.39)). The highest (≥ 11 servings/week of red meat and poultry; ≥ 3 servings/week of processed meat) versus the lowest (0–3 servings/week of red meat and poultry; 0 serving/week of processed meat) consumption of all other types of meats, including red meat, poultry and processed meat, showed no association with NAFLD (1.17 (0.75, 1.81), 1.02 (0.42, 2.50) and 0.85 (0.50, 1.45), respectively). Aquatic and sea food, and red meat had negative indirect effects on NAFLD via systolic blood pressure and/or high-density lipoprotein cholesterol. Processed meat had positive indirect effects on NAFLD via body mass index, waist circumference, fasting plasma glucose and triglycerides.ConclusionHigh consumption of fatty fish was associated with higher NAFLD risk. Our results, if causal, provide evidence that limiting consumption of fatty fish can be considered as part of NAFLD lifestyle prevention and treatment.

P115: Testing the feasibility of a multicomponent neuropsychological intervention for individuals at-risk of dementia: the REMINDER program

Objective:Interventions aimed to optimize cognitive function and functionality in individuals at risk of dementia were scarce in validity studies. While some RCTs have been developed in cognitive training interventions, studies of multicomponent interventions (cognitive, social, and behavioral) integrating intervention targeting psychosocial risk factors (social isolation, depression, low cognitive reserve) is absent. Additionally, few efforts have been made to develop such validity studies with individuals at higher risk of dementia who still do not present objective cognitive decline, despite current recommendations in this regard. We aimed to start the validation of a 20-session multicomponent intervention – REMINDER program - with a feasibility test and a preliminary efficacy testing using a comprehensive outcome assessment protocol.Methods:A feasibility randomized controlled trial (RCT) was conducted, recruiting community-dwelling individuals between 60 to 75 years old with increased risk of dementia (LIBRA dementia risk score). Fifteen participants took part in twice-a-week sessions of the REMINDER program, during twelve weeks. Data on the acceptability, satisfaction and adherence to the REMINDER program was collected, and an association between pre and post intervention motivation and knowledge about dementia risk was examined. For the preliminary efficacy testing we considered as primary outcome a performance-based functionality measure (UPSA) and secondary outcomes will include global cognition, emotional status, and lifestyle habits, tested prior and after the intervention.Results:Rates of satisfaction throughout the REMINDER program sessions were high (75%, mean) as well as the adherences that was superior to the main dementia risk reduction programs referred in literature. (83%). Post-intervention efficacy testing is ongoing, however, levels of knowledge about dementia risk increased 12% compared with pre-intervention (34% pre-intervention, to 46% post intervention; p=.045)Discussion:Preliminary data on feasibility and efficacy of the REMINDER program suggests this program is an engaging and motivating tool for dementia risk reduction, justifying the future implementation of a large-scale RCT. We expect that, with a larger efficacy study we can demonstrate the REMINDER program effects in behavior change and in the adoption of protective lifestyles for dementia prevention, and that the comprehensive outcome assessment proves to be effective and, therefore, replicable in further studies.

Prevention of Alzheimer’s by a Multimodal Lifestyle Protocol – Working‐mechanisms for Memory Gains: Mouse‐PAW

AbstractBackgroundThe approach of changing multiple lifestyle factors simultaneously targeting different risk factors is expected to have the greatest potential in preventing or delaying the progression of dementia. Nevertheless, it is largely unidentified what are the biological working mechanism underlying the positive findings from clinical trials of multimodal lifestyle interventions.MethodWe have set up a novel protocol to study multimodal lifestyle intervention in mice. The protocol was developed to recapitulate the FINGER (NCT01041989) and MIND‐AD (NCT03249688) clinical trials. In the lifestyle Prevention of Alzheimer’s Working‐mechanisms (PAW) group, mice were given access to running wheels (voluntary exercise), Fortasyn Connect (healthy diet), and they were subjected to cognitive training in an IntelliCage (IC) environment. To separately investigate the effects of an intervention resembling vascular monitoring, a group of mice was given Atorvastatin and Enalapril mixed in the diet. Control mice were housed in normal conditions. We included 12 wild‐type female C57BL/J6 mice six‐months‐of‐age per group. The full intervention lasted for 8 weeks.ResultThe study aimed to evaluate the feasibility of this innovative housing setup that provides a lifestyle intervention for the mice. The housing setup furthermore provides diverse data for individual mice on their learning and physical activity. Definite strengths of the protocol are the minimal need for mouse handling, the possibility of group housing, and that the intervention runs fully in a homecage environment. During the intervention, the PAW group undergoes cognitive training in the form of learning the location (corner) of a bottle from which they receive water (positive reinforcement). Regardless of individual variation in learning different cognitive training paradigms, PAW mice on a group level were able to reduce the error rates (incorrect corner visits) by approximately 25% in all paradigms.ConclusionWe constructed a way of performing multimodal lifestyle intervention in mice in a homecage environment, which provides a platform for detailed mechanistic studies. Moreover, our protocol minimizes stress due to handling and provides quantitative data for both cognitive training and exercise. The future steps involve studying animal models of cognitive decline, Alzheimer’s disease and vascular/metabolic dysfunction to assess mechanisms impacted by lifestyle change.

Synergistic contributions of vascular risk factors and APOE ε4 carriage to cognitive performance in middle‐aged adults enrolled in the Healthy Brain Project

AbstractBackgroundMidlife vascular risk factors (VRFs) and APOE ε4 carriage are individually associated with poor cognitive performance and increased dementia risk. However, the extent to which VRFs interact with APOE ε4 carriage to influence cognition in midlife remains unclear. This study aimed to investigate interactions between VRFs and APOE status on cognitive performance in cognitively normal (CN) middle‐aged adults.MethodCN adults aged 40‐70 enrolled in the Healthy Brain Project with ≥75% complete baseline data on five VRFs and APOE status were included (N = 1610; 546 ε4 carriers). Cardiovascular risk was operationalized by assessing history of hypertension, hypercholesterolemia, diabetes mellitus, body mass index (BMI) ≥25, and current cigarette smoking. Participants were categorized into low (0) or high vascular risk groups (≥1 VRF) determined via median split. Analyses of covariance (ANCOVAs) investigated interactions between VRF group × APOE status on attention and memory composites (derived from the Cogstate Brief Battery), controlling for age, sex, education, ethnicity, and depressive/anxiety symptoms. Linear regression analyses explored contributions of individual VRFs on memory in ε4 carriers and non‐carriers.ResultA significant VRF group × APOE status interaction was observed for memory (p = .04), but attention was lower in those at high vascular risk, regardless of APOE ε4 status (Table 1, Figure 1A and 1B). For memory, APOE ε4 carriers with high vascular risk demonstrated worse performance compared to ε4 carriers and non‐carriers with low vascular risk (Figure 1A and 1B). Linear regression analyses revealed that BMI ≥25 and hypercholesterolemia were significantly associated with worse memory performance in ε4 carriers only (Table 2).ConclusionIn CN middle‐aged adults, vascular risk significantly modified associations between APOE status and memory performance, such that ε4 carriers with high vascular risk demonstrated the lowest memory performance. More specifically, higher BMI and hypercholesterolemia were significantly associated with lower observed memory performance within this group. Results suggest that middle‐aged ε4 carriers with vascular risk factors may be an important sub‐group to target within lifestyle prevention trials to reduce future risk of cognitive impairment and decline.

Abstract 12895: Classification of Patients According to the Cardiometabolic-Based Chronic Disease Model in a Preventive Cardiology Center

Introduction: Cardiovascular disease results from complex interactions between metabolic drivers. The purpose of the novel cardiometabolic-based chronic disease model is to expose opportunities for early and sustainable prevention. Hypothesis: The cardiometabolic-based chronic disease (CMBCD) model allows allocation of patients with stage 1 (“risk”), stage 2 (“predisease”), stage 3 (“disease”), and stage 4 (“complications”) of each of the four metabolic drivers - adiposity, dysglycemia, dyslipidemia, and hypertension. Methods: Patients with a visit at the Center for Cardiovascular Health at Mount Sinai Heart, a multidisciplinary preventive cardiology center, were classified according to the CMBCD model relative to baseline characteristics. The context of this classification is the determination, based on statistical and mechanistic corroboration, of a dominant driver to be used to subsequently determine response and sustainability rates. Results: The most frequent dominant driver was adiposity-based chronic disease, in 642 (76.9%) patients, followed by dysglycemia-based chronic disease, in 104 (12.5%), hypertension-based chronic disease in 76 (7.5%), and lipid-based chronic disease in 13 (1.3%). A very large proportion of patients with adiposity-, dysglycemia-, and hypertension-based chronic disease (49%, 57%, and 25%, respectively) present with “complications” of “predisease” and “disease”. Conclusions: Abnormal adiposity and dysglycemia have proximal roles in the pathogenesis of cardiovascular disease in the cardiometabolic-based chronic disease model. This presents a window of opportunity for early lifestyle prevention strategies.

Older adults' perspectives towards optimizing lifestyle behaviors and strategies to support healthy brain ageing during COVID-19 restrictions.

It is unknown how the impact of COVID-19 restrictions has affected brain healthy behaviors that contribute to dementia risk reduction in older adults. Our aim was to explore perspectives of older adults on lifestyle behaviors that support positive brain health and dementia risk reduction during and following COVID-19 restrictions. Community-dwelling older Australians (N = 159) during June to October 2021 (the second wave of COVID-19 restrictions) who had taken part in a pre-post dementia risk reduction intervention program were invited to discuss the impact of COVID-19 on their lifestyle behaviors. Semi-structured interviews explored individual's adaptability to pandemic restrictions, intended behavior changes following restrictions easing, and feedback on the effectiveness of ongoing intervention programs for sustaining brain health. Thematic data analysis was performed using a deductive approach. Participants had an average age of 73.1 years (SD = 5.6; range: 65-90), majority were female (74.7%), lived in a major city (82.2%) and mean 9.5 years (SD = 1.7) of education. Older adults' views about lifestyle prevention strategies during the pandemic were both positive (e.g., more spare time and adaptive leisure activities) and negative (e.g., social isolation, lack of motivation, adverse emotions). Participants highlighted a continuous conscious effort to adapt certain brain healthy behaviors despite the persistence of adverse impacts of COVID-19 restrictions. Participants also expressed the intention and desire to revert to their previous lifestyle before the COVID-19 pandemic or a sense of the 'new normal'. This formative research will inform future interventions targeting dementia risk reduction to consider the immediate and lasting effects of COVID-19 restrictions on older adult's lifestyle behavior.

Improving secondary prevention knowledge in immigrants after a heart attack: adapting and evaluating a virtual patient education resource to promote behaviour change

Abstract Funding Acknowledgements Type of funding sources: None. Background Coronary heart disease (CHD) is prevalent and recurrent (40%), whereas an estimated 75% of events could be avoided by secondary prevention of modifiable risk factors and healthy lifestyle. Structured in-person secondary prevention and patient education programs are both efficient and effective strategies; however, these programs may not meet immigrants’ care or home-based learning needs, and thus alternative educational models are needed. Purpose To adapt and evaluate the simplified Chinese version of Cardiac College, a co-designed evidence-based virtual patient education resource for heart attack, in Chinese immigrants on secondary prevention knowledge and behaviour change outcomes. Methods A prospective longitudinal pre-post study was undertaken in heart attack survivors recruited from cardiac rehabilitation programs at four metropolitan tertiary hospitals from May 2021 to November 2022. Chinese Cardiac College intervention was adapted and provided education via nine booklets and 10 pre-recorded video sessions structured and delivered to patients for four weeks following hospital discharge. Validated surveys measured health literacy, disease-related knowledge, physical activity, heart-healthy diet, and self-management behaviours at baseline and one to two weeks post-intervention. Acceptability, engagement, and satisfaction were also assessed post-intervention. Results From 81 patients assessed for eligibility, 67 were recruited, and 64 (95.5%) completed the study. The sample was aged mean 67.23 ± 8.12 years, and 81.25% were males. Participants had significant improvement in disease-related knowledge in total and in each domain, with the most improvement identified in medical, followed by exercise and psychological domains (p&amp;lt;0.001) (Table 1). Healthy dietary behaviour and other self-management behaviours also significantly improved (all p&amp;lt;0.05). All participants (100%) self-reported being engaged with the materials, rating content as highly acceptable (n=20, 31.3%) and highly satisfactory (n=30, 46.9%). In addition, most participants reported that the delivered information amount was adequate (n=44, 68.8%), and 26.6% (n=17) found it overwhelming. Conclusion A virtual patient-education intervention adapted for Chinese immigrants (Chinese Cardiac College) significantly improves secondary prevention knowledge and self-care behaviour in heart attack survivors and offers a suitable model for intervention, especially where there are limited bilingual staff or resources. Further testing of randomised controlled trials and multiple populations is required.

MODELING THE EFFECTS OF TV AND SOCIAL MEDIA ADVERTISEMENTS ON DIABETES

Diabetes is a widespread non-contagious disease, and a significant fraction of human population in the world is affected by it. Lifestyle changes including physical activities and a healthy diet can prevent or delay the onset of diabetes and its complications. In this paper, nonlinear mathematical models are proposed and analyzed to study the role of awareness in the prevention of diabetes. In model formulation, first it is assumed that the unaware people become aware through word-of-mouth communication only and adopt a preventive lifestyle to reduce the peril of diabetes. Subsequently, the proposed model is extended by incorporating the effect of social media and TV advertisements on diabetes awareness. An awareness generation number is obtained for the first model and it is found that the system exhibits transcritical bifurcation when this number crosses unity. Both models are analyzed qualitatively and a comparison of outcomes reveals that social media and TV ads are more effective in raising the level of awareness among individuals and helps to inhibit the risk of diabetes mellitus. The analytical results are verified through numerical simulation.
