RESUMO
INTRODUCTION: The prevalence of mild and major neurocognitive disorders (NCDs), also referred to as mild cognitive impairment and dementia, is rising globally. The prevention of NCDs is a major global public health interest. We sought to synthesize the literature on potentially modifiable risk factors for NCDs. METHODS: We conducted an umbrella review using a systematic search across multiple databases to identify relevant systematic reviews and meta-analyses. Eligible reviews examined potentially modifiable risk factors for mild or major NCDs. We used a random-effects multi-level meta-analytic approach to synthesize risk ratios for each risk factor while accounting for overlap in the reviews. We further examined risk factors for major NCD due to two common etiologies: Alzheimer's disease and vascular dementia. RESULTS: A total of 45 reviews with 212 meta-analyses were synthesized. We identified fourteen broadly defined modifiable risk factors that were significantly associated with these disorders: alcohol consumption, body weight, depression, diabetes mellitus, diet, hypertension, less education, physical inactivity, sensory loss, sleep disturbance, smoking, social isolation, traumatic brain injury, and vitamin D deficiency. All 14 factors were associated with the risk of major NCD, and five were associated with mild NCD. We found considerably less research for vascular dementia and mild NCD. CONCLUSION: Our review quantifies the risk associated with 14 potentially modifiable risk factors for mild and major NCDs, including several factors infrequently included in dementia action plans. Prevention strategies should consider approaches that reduce the incidence and severity of these risk factors through health promotion, identification, and early management.

As the COVID-19 pandemic impacted mental health, this longitudinal study examined the effect of age-friendly communities (AFC) action plan on older adults' depressive symptoms. Using the CLSA, the CLSA COVID-19 Questionnaire study, survey of Canadian municipalities, and the census, the depressive symptoms trajectories were modeled with multilevel multinomial regressions. Most respondents (66.1%) had non-depressed trajectories, 28.1% experienced a moderate increase in depressive symptoms, and 5.8% had a depressed trajectory. AFC action plans did not have a protective effect on these trajectories. Being a female, greater loneliness, lower income, ≥2 chronic conditions, inferior social participation, weaker sense of belonging, COVID-19 infection, and pandemic stressors predicted a depressed trajectory. Neighborhood's deprivation had a weak protective effect on the declining trajectory. Although AFC action plans provided no benefits during the pandemic, volunteers facilitating resource access and social interactions could limit any increase in depressive symptoms.

BACKGROUND: Although HIV-related deaths among people with HIV have dramatically decreased, deaths from other medical conditions and non-medical events have increased. The location of death among people with HIV remains underreported. OBJECTIVES: We reviewed the deaths, causes of death, and reported location of death (i.e. within or outside of medical settings) of all people with HIV with the Southern Alberta Cohort, Calgary, Canada, between 1 January 2010 and 1 January 2022. METHODS: This was a retrospective longitudinal cohort study reviewing all deaths within a comprehensive geographically defined HIV cohort over 11 years. RESULTS: Deaths from HIV-related causes decreased from 52% of all deaths in 2010 to 14% in 2021. In 2021, non-HIV medical deaths increased from 38% to 44%, and non-medical deaths (e.g. violence, suicide, drug overdose) increased from 0.5% to 39%. Of non-medical deaths, 67% resulted from substance use/overdose. Overall, deaths in any medical setting decreased from 91% in 2010 to 39% in 2021; 61% of all deaths occurred in a medical setting (e.g. hospital/emergency department or supported/long-term/hospice care), 27% in a residence, and 9% in the community. CONCLUSION: The shifting causes of death (i.e. fewer HIV-related deaths, more overdose deaths) and location of death (i.e. fewer in medical settings, more at home/in the community) requires close monitoring so future resources can be matched to predicted patient needs.

OBJECTIVES: Determine whether levels of anxiety and depression, cognitive ability, and self-quarantining during and prior to the pandemic predict decreases in perceived functional ability. DESIGN AND SETTING: Longitudinal data collected from the Canadian Longitudinal Study on Aging (CLSA) COVID-19 Questionnaire Study (2020) and core CLSA study (Follow-Up 1; 2014-2018). PARTICIPANTS: 17 541 CLSA participants. MEASUREMENTS: Self-quarantining behaviours from questionnaires administered at Baseline (April 2020), Monthly, and Exit (December 2020) time points of the CLSA COVID-19 Questionnaire Study, levels of anxiety and depression at Baseline, perceived change in functional ability at Exit, and performance on neuropsychological tests (Rey Auditory Verbal Learning Task, Mental Alternation Task, Animal Fluency Test) and functional ability (Older Americans Resources and Services [OARS] Multidimensional Assessment Questionnaire) from the core CLSA study. RESULTS: Greater cognitive ability pre-pandemic (B = -.003, P < .01), higher levels of anxiety (B = -.024, P < .01) and depressive symptoms (B = -.110, P < .01) at Baseline, and higher frequency of engaging in self-quarantining throughout the COVID-19 survey period (B = -.098, P < .01) were associated with perceived loss in functional ability at Exit. Self-quarantining behaviour was associated with perceived loss in functional ability only at average and high levels of depressive symptoms (B = -.013, P < .01). CONCLUSIONS: Older adults with higher cognitive and lower functional ability prior to the pandemic were at greater risk of decreased perceived functional ability during the first year of the pandemic, as were those who experienced greater levels of anxiety and depressive symptoms during the pandemic. Strategies/interventions to preserve functional ability in older adults with cognitive independence prior to future pandemics are warranted.

Background: The COVID-19 pandemic required implementation of public health measures to reduce the spread of SARS CoV-2. This resulted in social isolation and loneliness for many older adults. Loneliness and social isolation are associated with cognitive decline, however, the impact of this during COVID-19 has not been fully characterized. Objective: The aim of this scoping review was to explore the impact of social isolation and loneliness during COVID-19 on cognition in older adults. Eligibility criteria: Eligible studies occurred during the COVID-19 pandemic, enrolled older adults and reported longitudinal quantitative data on both loneliness (exposure) and cognition (outcome). Sources of evidence: A comprehensive search was conducted in CINAHL, Medline, PubMed, and Psychinfo databases (updated October 10, 2023). Charting methods: Studies were screened independently by two reviewers and study characteristics, including participant demographics, loneliness and cognition measurement tools, study objectives, methods and results were extracted. Results: The search yielded 415 results, and seven were included in the final data synthesis. All studies were conducted between 2019 and 2023. Six studies enrolled community-dwelling individuals while the remaining study was conducted in long-term care. In 6 studies, loneliness and/or social isolation was correlated with poorer cognitive function. In the seventh study, subjective memory worsened, while objective cognitive testing did not. Conclusion: Loneliness and social isolation during COVID-19 were correlated with cognitive decline in older adults. The long-term effect of these impacts remains to be shown. Future studies may focus on interventions to mitigate the effects of loneliness and social isolation during future pandemics.
RESUMO
People with HIV (PWH) are at increased risk of COVID-19 infection. Both Canadian (NACI) and US (CDC) guidelines recommend that all PWH receive at least 2 doses of COVID-19 vaccine, and a booster. We examined vaccination uptake among PWH in Southern Alberta, Canada. Among adult PWH, we evaluated COVID-19 vaccination uptake between December 2020 and August 2022. Poisson regression models with robust variance (approximating log binomial models) estimated crude and adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) for receiving (1) any vs. no vaccine, and (2) primary series with booster (≥ 3 vaccines) versus primary series without booster. Among 1885 PWH, 10% received no COVID-19 vaccinations, 37% < 3 vaccines and 54% received ≥ 3 vaccines. Females (vs. males) were less likely to receive a vaccine booster. Receiving no COVID-19 vaccines was associated with White ethnicity, unsuppressed HIV viral load (> 200 copies/mL), and using illegal substances. Factors associated with decreased booster uptake included being younger, Black (vs. White) ethnicity, substance use, lower educational attainment, and having an unsuppressed HIV viral load. COVID-19 booster uptake among PWH does not meet vaccine guidelines, and receipt of vaccines is unevenly distributed. Booster uptake is lowest among young females and marginalized individuals. Focused outreach is necessary to close this gap.

OBJECTIVES: Our objective was to report the baseline characteristics of participants in the Canadian HIV and Aging Cohort Study (CHACS) and present amendments to the initial protocol. METHODS: CHACS is a multi-centred prospective cohort study that was initially set from 2011 to 2016 and will now continue recruitment until 2024. Four additional years of follow-up have been added, and additional outcomes and covariates will be prospectively collected. Frailty will be assessed using a modified version of the Fried's frailty phenotype. The four interrelated aspects of gender-gender roles, gender identity, gender relationships, and institutionalized gender-will be measured using the GENESIS-PRAXY questionnaire. Diet will be assessed using a validated, web-based, self-administered food frequency questionnaire. RESULTS: A total of 1049 participants (77% people living with HIV) were recruited between September 2011 and September 2019. Median age at baseline was 54 years (interquartile range 50-61). Most participants were male (84%) and white (83%). Compared with participants without HIV, those with HIV were more likely to be male; to report lower education levels and incomes; to be more sedentary; to use tobacco, recreational, and prescription drugs; to report a personal history of cardiovascular diseases; and to be frail. CONCLUSIONS: The new assessments added to the CHACS protocol will allow for an even more detailed portrait of the pathways leading to accentuated aging for people living with HIV. Participants in the CHACS cohort display important differences in socio-economic and cardiovascular risk factors according to HIV serostatus. These imbalances must be taken into account for all further inferential analyses.

BACKGROUND: Older adults have been disproportionately impacted by COVID-19 and related preventative measures undertaken during the pandemic. Given clear evidence of the relationship between loneliness and health outcomes, it is imperative to better understand if, and how, loneliness has changed for older adults during the COVID-19 pandemic, and whom it has impacted most. METHOD: We used "pre-pandemic" data collected between 2015-2018 (n = 44,817) and "during pandemic" data collected between Sept 29-Dec 29, 2020 (n = 24,114) from community-living older adults participating in the Canadian Longitudinal Study on Aging. Loneliness was measured using the 3-item UCLA Loneliness Scale. Weighted generalized estimating equations estimated the prevalence of loneliness pre-pandemic and during the pandemic. Lagged logistic regression models examined individual-level factors associated with loneliness during the pandemic. RESULTS: We found the adjusted prevalence of loneliness increased to 50.5% (95% CI: 48.0%-53.1%) during the pandemic compared to 30.75% (95% CI: 28.72%-32.85%) pre-pandemic. Loneliness increased more for women (22.3% vs. 17.0%), those in urban areas (20.8% vs. 14.6%), and less for those 75 years and older (16.1% vs. 19.8% or more in all other age groups). Loneliness during the pandemic was strongly associated with pre-pandemic loneliness (aOR 4.87; 95% CI 4.49-5.28) and individual level sociodemographic factors [age < 55 vs. 75 + (aOR 1.41; CI 1.23-1.63), women (aOR 1.34; CI 1.25-1.43), and no post-secondary education vs. post-secondary education (aOR 0.73; CI 0.61-0.86)], living conditions [living alone (aOR 1.39; CI 1.27-1.52) and urban living (aOR 1.18; CI 1.07-1.30)], health status [depression (aOR 2.08; CI 1.88-2.30) and having two, or ≥ three chronic conditions (aOR 1.16; CI 1.03-1.31 and aOR 1.34; CI 1.20-1.50)], health behaviours [regular drinker vs. non-drinker (aOR 1.15; CI 1.04-1.28)], and pandemic-related factors [essential worker (aOR 0.77; CI 0.69-0.87), and spending less time alone than usual on weekdays (aOR 1.32; CI 1.19-1.46) and weekends (aOR 1.27; CI 1.14-1.41) compared to spending the same amount of time alone]. CONCLUSIONS: As has been noted for various other outcomes, the pandemic did not impact all subgroups of the population in the same way with respect to loneliness. Our results suggest that public health measures aimed at reducing loneliness during a pandemic should incorporate multifactor interventions fostering positive health behaviours and consider targeting those at high risk for loneliness.

As the coronavirus disease (COVID-19) pandemic prolongs, documenting trajectories of the socioeconomic gradient of mental health is important. We describe changes in the prevalence and absolute and relative income-related inequalities of mental health between April and December 2020 in Canada. We used data from the Canadian Longitudinal Study on Aging (CLSA) COVID-19 Questionnaire Study and the pre-pandemic CLSA Follow-up 1. We estimated the prevalence proportion, the concentration index (relative inequality), and the generalized concentration index (absolute inequality) for anxiety and self-reported feeling generally unwell at multiple points in April-December 2020, overall, by sex and age group, by region, and among those who reported poor or fair overall health and mental health pre-pandemic. Overall, the prevalence of anxiety remained unchanged (22.45 to 22.10%, p = 0.231), but self-reported feeling generally unwell decreased (9.83 to 5.94%, p = 0.004). Relative and absolute income-related inequalities were unchanged for both anxiety and self-reported feeling generally unwell, with exceptions of an increased concentration of self-reported feeling generally unwell among the poor, measured by the concentration index, overall (-0.054 to -0.115, p = 0.004) and in Ontario (-0.035 to -0.123, p = 0.047) and British Columbia (-0.055 to -0.141, p = 0.044). The COVID-19 pandemic appeared to neither exacerbate nor ameliorate existing income-related inequalities in mental health among older adults in Canada between April and December 2020. Continued monitoring of inequalities is necessary.

BACKGROUND: Symptom persistence in non-hospitalized COVID-19 patients, also known as Long COVID or Post-acute Sequelae of COVID-19, is not well characterized or understood, and few studies have included non-COVID-19 control groups. METHODS: We used data from a cross-sectional COVID-19 questionnaire (September-December 2020) linked to baseline (2011-2015) and follow-up (2015-2018) data from a population-based cohort including 23,757 adults 50+ years to examine how age, sex, and pre-pandemic physical, psychological, social, and functional health were related to the severity and persistence of 23 COVID-19-related symptoms experienced between March 2020 and questionnaire completion. RESULTS: The most common symptoms are fatigue, dry cough, muscle/joint pain, sore throat, headache, and runny nose; reported by over 25% of participant who had (n = 121) or did not have (n = 23,636) COVID-19 during the study period. The cumulative incidence of moderate/severe symptoms in people with COVID-19 is more than double that reported by people without COVID-19, with the absolute difference ranging from 16.8% (runny nose) to 37.8% (fatigue). Approximately 60% of male and 73% of female participants with COVID-19 report at least one symptom persisting >1 month. Persistence >1 month is higher in females (aIRR = 1.68; 95% CI: 1.03, 2.73) and those with multimorbidity (aIRR = 1.90; 95% CI: 1.02, 3.49); persistence >3 months decreases by 15% with each unit increase in subjective social status after adjusting for age, sex and multimorbidity. CONCLUSIONS: Many people living in the community who were not hospitalized for COVID-19 still experience symptoms 1- and 3-months post infection. These data suggest that additional supports, for example access to rehabilitative care, are needed to help some individuals fully recover.
Some people who develop COVID-19 experience persistence of symptoms. Here, we aimed to understand the factors associated with the severity and persistence of these symptoms in adults 50 years and older living in the community who had COVID-19. Using information provided by 23,757 participants from across Canada we compared the symptoms between those who had COVID-19 and those who did not. The number and severity of symptoms in participants who had COVID-19 was beyond what would be expected due to other causes. Over two-thirds of participants who had COVID-19 reported symptoms persisting for more than one month, and over half of the participants more than three months. Symptom persistence was higher in females, those with multiple chronic conditions, and lower perceived social status. This suggests that a substantial proportion of people who were not hospitalized for COVID-19 may require further healthcare assistance.
RESUMO
BACKGROUND: frailty imparts a higher risk for hospitalisation, mortality and morbidity due to COVID-19 infection, but the broader impacts of the pandemic and associated public health measures on community-living people with frailty are less known. METHODS: we used cross-sectional data from 23,974 Canadian Longitudinal Study on Aging participants who completed a COVID-19 interview (Sept-Dec 2020). Participants were included regardless of whether they had COVID-19 or not. They were asked about health, resource, relationship and health care access impacts experienced during the pandemic. Unadjusted and adjusted prevalence of impacts was estimated by frailty index quartile. We further examined if the relationship with frailty was modified by sex, age or household income. RESULTS: community-living adults (50-90 years) with greater pre-pandemic frailty reported more negative impacts during the first year of the pandemic. The frailty gradient was not explained by socio-demographic or health behaviour factors. The largest absolute difference in adjusted prevalence between the most and least frail quartiles was 15.1% (challenges accessing healthcare), 13.3% (being ill) and 7.4% (increased verbal/physical conflict). The association between frailty and healthcare access differed by age where the youngest age group tended to experience the most challenges, especially for those categorised as most frail. CONCLUSION: although frailty has been endorsed as a tool to inform estimates of COVID-19 risk, our data suggest it may have a broader role in primary care and public health by identifying people who may benefit from interventions to reduce health and social impacts of COVID-19 and future pandemics.

COVID-19 has negatively affected the mental health and well-being of adults, and thus it is important to examine potential factors which may influence mental health during the pandemic. We thus examined the association between pet ownership and depression/anxiety symptoms based on mental health disorder status during the COVID-19 pandemic. We included 12,068 cognitively healthy participants (45-86 years at study entry) from the Canadian Longitudinal Study on Aging (CLSA) comprehensive cohort who completed the first follow-up ([FU1]; 2015-2018), and COVID-19 Survey entry (April-May 2020) and exit (September-December 2020). Participants self-reported at FU1 if they owned a pet (yes/no). Participants were dichotomized as with or without a mental health disorder based on self-reported diagnosis of depression, anxiety, or mood disorders at baseline assessment (2011-2015) or FU1. Depressive symptoms were indexed using the 10-item Center for Epidemiological Studies Depression Scale (CESD-10) at FU1, and COVID-19 entry/exit surveys. Anxiety symptoms were assessed using the General Anxiety Disorder Questionnaire (GAD-7) at COVID-19 entry/exit surveys. Final models adjusted for age, sex, body mass index, income, education, living status, smoking status, relationship status, and alcohol intake. Forty-percent of participants owned a pet at FU1. Among those without a mental health disorder, there were no significant differences in CESD-10 between participants who owned pets compared with those without pets. For people with a mental health disorder, pet owners had higher CESD-10 (estimated mean difference range: 0.56-1.02 points; p < 0.05) and GAD-7 scores (estimated mean difference range: 0.28-0.57 points; p < 0.05) at both COVID-19 entry and exit surveys. Among people with mental health disorders, pet ownership was associated with poor mental health symptoms during April 2020 to December 2020 of the COVID-19 pandemic.
RESUMO
Importance: Loneliness and social isolation are public health concerns faced by older adults due to physical, cognitive, and psychosocial changes that develop with aging. Loneliness and social isolation are associated with increased morbidity and mortality. Objective: To evaluate interventions, targeting older adults, associated with a reduction in loneliness and social isolation. Data Sources: OVID, CINAHL, CENTRAL, Embase, PsychINFO, Web of Science, and Scopus were searched from inception to March 2020. Study Selection: Peer-reviewed randomized clinical trials measuring loneliness and social isolation or support in adults aged 65 years or older. Only English language articles were included. Data Extraction and Synthesis: Two independent reviewers screened studies, extracted data, and assessed risk of bias. Random-effects models were performed to pool the overall effect size by intervention. Statistical heterogeneity was evaluated with the I2 statistic and by estimating prediction intervals. Data were analyzed from November 2021 to September 2022. Main Outcomes and Measures: Quantitative measures of loneliness, social isolation, or social support based on an effect size of standardized mean differences. Results: Seventy studies were included in the systematic review (8259 participants); 44 studies were included in the loneliness meta-analysis (33 in the community with 3535 participants; 11 in long-term care with 1057 participants), with participants' ages ranging from 55 to 100 years. Study sizes ranged from 8 to 741 participants. Interventions included animal therapy, psychotherapy or cognitive behavioral therapy, multicomponent, counseling, exercise, music therapy, occupational therapy, reminiscence therapy, social interventions, and technological interventions. Most interventions had a small effect size. Animal therapy in long-term care, when accounting for studies with no active controls, had the largest effect size on loneliness reduction (-1.86; 95% CI, -3.14 to -0.59; I2 = 86%) followed by technological interventions (videoconferencing) in long-term care (-1.40; 95% CI, -2.37 to -0.44; I2 = 70%). Conclusions and Relevance: In this study, animal therapy and technology in long-term care had large effect sizes, but also high heterogeneity, so the effect size's magnitude should be interpreted with caution. The small number of studies per intervention limits conclusions on sources of heterogeneity. Overall quality of evidence was very low. Future studies should consider measures of social isolation in long-term care and identify the contextual components that are associated with a reduction in loneliness.

INTRODUCTION: In Canada, pneumococcal vaccination is recommended to all adults aged ≥65 and those <65 who have one or more chronic medical conditions (CMCs). Understanding vaccine uptake and its determinants among eligible groups has important implications for reducing the burden of pneumococcal disease. METHODS: Using data from a large national cohort of Canadian residents aged ≥47 years between 2015-2018, we calculated self-reported pneumococcal vaccine uptake among eligible groups, estimated associations between key factors and non-vaccination, assessed missed opportunities for vaccination (MOV) and examined risk factors for MOV. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for relevant associations were estimated through logistic regression. RESULTS: 45.8% (95% CI: 45.2-46.5) of 22,246 participants aged ≥65 and 81.3% (95% CI: 80.5-82.0) of 10,815 individuals aged 47-64 with ≥1 CMC reported never having received a pneumococcal vaccine. Receipt of influenza vaccination in the previous year was associated with the lowest odds of pneumococcal non-vaccination (aOR = 0.14 [95% CI: 0.13-0.15] for older adults and aOR = 0.23 [95% CI: 0.20-0.26] for those aged 47-64 with ≥1 CMC). Pneumococcal vaccine uptake was also more likely in case of contact with a family doctor in the previous year (versus no contact), increased with age and varied widely across provinces. Among individuals recently vaccinated against influenza, 32.6% (95% CI: 31.9-33.4) of those aged ≥65 and 71.1% (95% CI: 69.9-72.3) of those aged 47-64 with ≥1 CMC missed an opportunity to get a pneumococcal vaccine. Among individuals who had contact with a family doctor, 44.8% (95% CI: 44.1-45.5) of those aged ≥65 and 80.4% (95% CI: 79.6-81.2) of those aged 47-64 with ≥1 CMC experienced a MOV. CONCLUSIONS: Pneumococcal vaccine uptake remains suboptimal among at-risk Canadian adults who are eligible for vaccination. Further research is needed to clarify the reasons behind missed opportunities for vaccination and adequately address the main barriers to pneumococcal vaccination.

BACKGROUND: Influenza vaccination is recommended in Canada for older adults and those with underlying health conditions due to their increased risk of severe outcomes. Further research is needed to identify who within these groups is not receiving influenza vaccine to identify opportunities to increase coverage. OBJECTIVES: We aimed to 1) estimate influenza non-vaccination prevalence and 2) assess factors associated with non-vaccination among Canadian adults aged ≥65 and adults aged 46-64 with ≥1 chronic medical condition (CMC) due to their high risk of severe influenza outcomes. METHODS: We conducted a secondary analysis of cross-sectional data collected from 2015-2018 among participants of the Canadian Longitudinal Study on Aging. For both groups of interest, we estimated non-vaccination prevalence and used logistic regression models to identify factors associated with non-vaccination. We report adjusted odds ratios and 95% confidence intervals for the investigated variables. RESULTS: Overall, 29.5% (95% CI: 28.9%, 30.1%) of the 23,226 participants aged ≥65 years and 50.4% (95% CI: 49.4%, 51.3%) of the 11,250 participants aged 46-64 years with ≥1 CMC reported not receiving an influenza vaccination in the past 12 months. For both groups, lack of recent contact with a family doctor and current smoking were independently associated with non-vaccination. DISCUSSION: Influenza vaccination helps prevent severe influenza outcomes. Yet, half of adults aged 46-64 years with ≥1 CMC and more than one-quarter of all adults aged ≥65 years did not receive a recommended influenza vaccine in the year prior to the survey. Innovation in vaccination campaigns for routinely recommended vaccines, especially among those without annual family doctor visits, may improve coverage. CONCLUSION: Influenza vaccination coverage among Canadian adults aged 46-64 years with ≥1 CMC and adults aged ≥65 years remains suboptimal. Vaccination campaigns targeting those at high risk of severe outcomes without routine physician engagement should be evaluated to improve uptake.

OBJECTIVE: To examine proportions and predictors of change in alcohol intake and binge drinking during the first 2 waves of the COVID-19 pandemic among middle-aged and older participants in the Canadian Longitudinal Study on Aging (CLSA) COVID-19 Questionnaire Study. METHODS: A total of 28,559 (67.2% of the potential sample) CLSA participants consented to the study with 24,114 completing the exit survey (fall 2020). Descriptive statistics and logistic regressions to examine predictors of change (increase or decrease) in alcohol intake and binge drinking were performed. RESULTS: Among alcohol users, 26.3% reported a change in alcohol consumption during the first 10 months of the pandemic. Similar percentages increased (13.0%) or decreased (13.3%) consumption. In our mutually adjusted logistic regression model, odds of change in alcohol intake were greater for younger age, higher income, current cannabis smoker, positive screen for depression, anxiety, and loneliness. The magnitude of all associations for decreased intake was less than that of increased intake, and the directions were opposite for male sex and age. Predictors of current binge drinking (27.9% of alcohol users) included male sex, younger age, higher education and income, cannabis use, depression, and anxiety. CONCLUSION: Factors predictive of potentially worrisome alcohol use (i.e. increased intake, binge drinking) included younger age, sex, greater education and income, living alone, cannabis use, and worse mental health. Some of these factors were also associated with decreased intake, but the magnitudes of associations were smaller. This information may help direct screening efforts and interventions towards individuals at risk for problematic alcohol intake during the pandemic.
RéSUMé: OBJECTIF: Examiner les proportions et les prédicteurs des changements dans la consommation d'alcool et l'hyperalcoolisation rapide au cours des deux premières vagues de la pandémie de COVID-19 chez les personnes âgées et d'âge moyen ayant participé à l'étude par questionnaire sur la COVID-19 de l'Étude longitudinale canadienne sur le vieillissement (ELCV). MéTHODE: Un total de 28 559 participants de l'ELCV (67,2 % de l'échantillon potentiel) ont consenti à l'étude sur la COVID-19, et 24 114 ont répondu à l'enquête à la sortie (automne 2020). Nous avons procédé par statistique descriptive et par régression logistique pour examiner les prédicteurs des changements (augmentation ou diminution) dans la consommation d'alcool et l'hyperalcoolisation rapide. RéSULTATS: Chez les consommateurs d'alcool, 26,3 % ont déclaré un changement de leur consommation d'alcool au cours des 10 premiers mois de la pandémie. Un pourcentage semblable de consommateurs d'alcool avaient accru (13 %) ou diminué (13,3 %) leur consommation. Dans notre modèle de régression logistique mutuellement ajusté, la probabilité de changement dans la consommation d'alcool était plus élevée chez les répondants plus jeunes, les répondants au revenu élevé, les fumeurs de cannabis actuels et les répondants ayant fait état de dépression, d'anxiété ou de solitude. Les associations avec la diminution de la consommation étaient moins significatives qu'avec l'augmentation de la consommation, et elles allaient dans le sens opposé pour ce qui est du sexe masculin et de l'âge. Les prédicteurs de l'hyperalcoolisation rapide actuelle (27,9 % des consommateurs d'alcool) étaient le sexe masculin, l'âge plus jeune, l'instruction et le revenu élevés, la consommation de cannabis, la dépression et l'anxiété. CONCLUSION: Les facteurs pouvant prédire une consommation d'alcool potentiellement inquiétante (c.-à-d. consommation accrue, hyperalcoolisation rapide) étaient l'âge plus jeune, le sexe, l'instruction et le revenu élevés, le fait de vivre seul, la consommation de cannabis et la moins bonne santé mentale. Certains de ces facteurs étaient aussi associés à une consommation réduite, mais ces associations étaient moins significatives. Ces informations pourraient orienter les efforts de dépistage et les interventions auprès des personnes à risque de consommation problématique d'alcool durant la pandémie.

Transthyretin amyloidosis cardiomyopathy (ATTR-CM) is commonly diagnosed in older adults, in particular the wild-type (ATTRwt), which is regarded as an age-related disease. With an aging population and improved diagnostic techniques, the prevalence and incidence of ATTR-CM will continue to increase. With increased availability of mortality reducing ATTR-CM therapies, patients are living longer. The predominant clinical manifestation of ATTR-CM is heart failure, while other cardiovascular manifestations include arrhythmia and aortic stenosis. Given their older age at diagnosis, patients often present with multiple age-related comorbidities, some of which can be exacerbated by ATTR, including neurologic, musculoskeletal, and gastrointestinal problems. Considerations related to older patient care, such as frailty, cognitive decline, polypharmacy, falls/mobility, functional capacity, caregiver support, living environment, quality of life and establishing goals of care are particularly important for many patients with ATTR-CM. Furthermore, the high cost ATTR treatments has increased interest in establishing improved predictors of response to therapy, with assessment of frailty emerging as a potentially important determinant. Multidisciplinary care inclusive of collaboration with geriatric and elder care medicine specialists, and others such as neurology, orthopedic surgery, electrophysiology and transcatheter aortic valve replacement clinics, is now an important component of ATTR-CM management. This review will examine current aspects of the management of older ATTR-CM patients, including shared care with multiple medical specialists, the emerging importance of frailty assessment and other considerations for using ATTR therapies.
RESUMO
BACKGROUND: 40-60% of people with HIV report experiencing loneliness, and 5-29% of PWH are frail (depending on the definition used). The risk of death in individuals who are frail and lonely, or frail and socially isolated has recently been estimated to be 1·8 times that in individuals who are not frail, lonely, or socially isolated. The aim of the present study was to determine the prevalence of loneliness, and other vulnerabilities related to ageing, in frail older adults with HIV. METHODS: We assessed frailty with the Clinical Frailty Scale (CFS) in a cross-sectional, convenience sample of people with HIV aged 50 years or older in Southern Alberta, Canada. All Southern Alberta Clinic patients aged 50 years or older who attended a virtual or in-person clinic visit between March and October, 2020, and who underwent frailty screening were included in the present analyses. Individuals scoring 4 or higher on the CFS then completed a structured questionnaire to provide information on additional co-factors, including loneliness (Three-item Loneliness Scale), falls, impaired gait and balance, polypharmacy, unintentional weight loss, food insecurity, and subjective cognitive concerns. Age, sex, nadir CD4 cell count, duration of known HIV infection, ethnicity, and risk category were evaluated for associations with frailty. We used t tests to compare means and Pearson χ2 tests to compare proportions. Patients gave written informed consent for use of data. The use of data was approved by the University of Calgary Conjoint Heath Research Ethics Board. FINDINGS: We assessed frailty in 292 older people with HIV. The mean age was 59 years (range 50-86 years) and 45 (16%) were women. On the basis of a score of 4 or greater on the CFS, 40 (14%) participants were identified as frail. Frail individuals tended to be older than those who were not frail (mean age 61·9 years, SD 8·5 versus 58·4 years, SD 6·3; t test difference 3·5, 95% CI 1·3-5·7; p=0·0011). However, there was no association between frailty status and sex, nadir CD4 cell count, duration of known HIV infection, or self-reported ethnicity. Frail individuals were more likely to report injection drug use as a component of their risk for acquisition than were non-frail individuals. Of the frail participants, 15 (42%) reported loneliness, 15 (42%) had fallen in the past year, and 18 (50%) reported impaired gait or balance. One-fifth (8) reported unintentional weight loss and 12 (33%) experienced food insecurity. Nearly 40% (14) reported subjective memory concerns. INTERPRETATION: In this sample of ageing people with HIV, frailty and loneliness were prevalent. Given the increased risk of death when frailty and loneliness are both present, upstream and targeted interventions are urgently needed. These might include measures to address loneliness, risk of falls, weight loss, food insecurity, and memory concerns.

Identifying persons who are least willing to receive a coronavirus disease 2019 (COVID-19) vaccine is critical for increasing uptake via targeted outreach. We conducted a survey of 23,819 Canadian Longitudinal Study on Aging participants from September 29 to December 29, 2020, to assess factors associated with COVID-19 vaccination willingness and reasons for willingness or lack thereof. Among adults aged 50-96 years, 84.1% (95% confidence interval (CI): 83.7, 84.6) were very or somewhat willing to receive a COVID-19 vaccine; 15.9% (95% CI: 15.4, 16.3) were uncertain or very or somewhat unwilling. Based on logistic regression, those who were younger, female, had lower education and income, were non-White, and lived in a rural area were less willing to receive a COVID-19 vaccine. After controlling for these factors, recent receipt of influenza vaccine (adjusted odds ratio = 14.3, 95% CI: 12.5, 16.2) or planning to receive influenza vaccine (adjusted odds ratio = 10.5, 95% CI: 9.5, 11.6), as compared with no receipt or planning, was most strongly associated with COVID-19 vaccination willingness. Willingness was also associated with believing one had never been infected with severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) and experiencing negative pandemic consequences. Safety concerns were most common among those unwilling. Our comprehensive assessment of COVID-19 vaccination willingness among older adults in Canada, a prioritized group for vaccination due to their risk of severe COVID-19 outcomes, provides a road map for conducting outreach to increase uptake, which is urgently needed.

OBJECTIVES: Studies on informal caregiving during the coronavirus disease 2019 (COVID-19) pandemic have mainly focused on subgroups of caregivers using cross-sectional or convenience samples, limiting the generalizability of findings. Conversely, this longitudinal study examines the effects of the pandemic and caregiving factors on depressive symptoms and anxiety over 9 months among informal caregivers in Canada. METHODS: This study uses data from the Baseline (2011-2015), Follow-up 1 (2015-2018), and COVID-19 Study Baseline survey (April to May 2020) and Exit surveys (September to December 2020) of the Canadian Longitudinal Study on Aging (CLSA). A total of 14,118 CLSA participants who were caregivers at Follow-up 1 and participated in the COVID-19 studies were selected. Linear mixed models were used to examine the effect of sex of caregiver, changes in caregiving (increase in caregiving hours and inability to care), and location of care (same household, another household, and health care institution) on depressive symptoms and anxiety from COVID-19 studies Baseline to Exit surveys (about 6-7 months apart). RESULTS: Informal caregivers reported more frequent depressive symptoms from the COVID-19 Baseline to Exit surveys, but not anxiety. Female caregivers reported greater depressive symptoms and anxiety, and male caregivers exhibited a greater increase in depressive symptoms and anxiety over time. More caregiving hours and inability to provide care were significantly positively associated with depressive symptoms and anxiety. Also, in-home caregivers reported more depressive symptoms and anxiety than those who cared for someone in health care institution, and more anxiety than those who cared for some in another household. DISCUSSION: The findings shed light on the change in mental health among informal caregivers during the outset of the pandemic. The demonstrated associations between studied variables and mental health among informal caregivers provide empirical evidence for intervention programs aiming to support caregivers, particularly those who are female, and providing intensive care at home.
