RESUMO
OBJECTIVES: The COVID-19 pandemic and accompanying public health measures exacerbated many known risk factors for depression, while also increasing numerous health-related stressors for people with stroke history. Using a large longitudinal sample of older adults, the current study examined the prevalence of incident and recurrent depression among participants with stroke history, and also identified factors that were associated with depression during the pandemic among this population. METHODS: Data came from four waves of the Canadian Longitudinal Study on Aging's (CLSA) comprehensive cohort (n = 577 with stroke history; 46.1% female; 20.8% immigrants; mean age = 74.56 SD = 9.19). The outcome of interest was a positive screen for depression, based on the CES-D-10, collected during the 2020 CLSA COVID autumn questionnaire. Bivariate and multivariate logistic regression analyses were conducted to identify factors that were associated with depression. RESULTS: Approximately 1 in 2 (49.5%) participants with stroke history and a history of depression experienced a recurrence of depression early in the pandemic. Among those without a history of depression, approximately 1 in 7 (15.0%) developed depression for the first time during this period. The risk of depression was higher among immigrants, those who were lonely, those with functional limitations, and those who experienced COVID-19 related stressors, such as increased family issues, difficulty accessing healthcare, and becoming ill or having a loved one become ill or die during the pandemic. CONCLUSIONS: Interventions that target those with stroke history, both with and without a history of depression, are needed to buffer against the stressors of the COVID-19 pandemic and support the mental health of this population.

BACKGROUND: People with obesity are at increased risk of chronic stress, and this may have been exacerbated during the COVID-19 pandemic. Adverse childhood experiences (ACE) are also associated with both obesity and stress, and may modify risk of stress among people with obesity. The objectives of this study were to evaluate the associations between obesity, ACEs, and stress during the pandemic, and to determine if the association between obesity and stress was modified by ACEs. METHODS: A longitudinal study was conducted among adults aged 50-96 years (n = 23,972) from the Canadian Longitudinal Study on Aging (CLSA) COVID-19 Study. Obesity and ACEs were collected pre-pandemic (2015-2018), and stress was measured at COVID-19 Exit Survey (Sept-Dec 2020). We used logistic, Poisson, and negative binomial regression to estimate relative risks (RRs) and 95% confidence intervals (CIs) for the associations between obesity, ACEs, and stress outcomes during the pandemic. Interaction by ACEs was evaluated on the additive and multiplicative scales. RESULTS: People with obesity were more likely to experience an increase in overall stressors (class III obesity vs. healthy weight RR = 1.19; 95% CI: 1.12-1.27) as well as increased health related stressors (class III obesity vs. healthy weight RR: 1.25; 95% CI: 1.12-1.39) but did not perceive the consequences of the pandemic as negative. ACEs were also associated an increase in overall stressors (4-8 ACEs vs. none RR = 1.38; 95% CI: 1.33-1.44) and being more likely to perceive the pandemic as negative (4-8 ACEs vs. none RR = 1.32; 95% CI: 1.19-1.47). The association between obesity and stress was not modified by ACEs. CONCLUSIONS: Increased stress during the first year of the COVID-19 pandemic was observed among people with obesity or ACEs. The long-term outcomes of stress during the pandemic need to be determined.

BACKGROUND: The growth of urban dwelling populations globally has led to rapid increases of research and policy initiatives addressing associations between the built environment and physical activity (PA). Given this rapid proliferation, it is important to identify priority areas and research questions for moving the field forward. The objective of this study was to identify and compare research priorities on the built environment and PA among researchers and knowledge users (e.g., policy makers, practitioners). METHODS: Between September 2022 and April 2023, a three-round, modified Delphi survey was conducted among two independent panels of international researchers (n = 38) and knowledge users (n = 23) to identify similarities and differences in perceived research priorities on the built environment and PA and generate twin 'top 10' lists of the most important research needs. RESULTS: From a broad range of self-identified issues, both panels ranked in common the most pressing research priorities including stronger study designs such as natural experiments, research that examines inequalities and inequities, establishing the cost effectiveness of interventions, safety and injuries related to engagement in active transportation (AT), and considerations for climate change and climate adaptation. Additional priorities identified by researchers included: implementation science, research that incorporates Indigenous perspectives, land-use policies, built environments that support active aging, and participatory research. Additional priorities identified by knowledge users included: built environments and PA among people living with disabilities and a need for national data on trip chaining, multi-modal travel, and non-work or school-related AT. CONCLUSIONS: Five common research priorities between the two groups emerged, including (1) to better understand causality, (2) interactions with the natural environment, (3) economic evaluations, (4) social disparities, and (5) preventable AT-related injuries. The findings may help set directions for future research, interdisciplinary and intersectoral collaborations, and funding opportunities.

BACKGROUND: Oral health plays a role in overall health, indicating the need to identify barriers to accessing oral care. The objective of this study was to identify barriers to accessing oral health care and examine the association between socioeconomic, psychosocial, and physical measures with access to oral health care among older Canadians. METHODS: A cross-sectional study was conducted using data from the Canadian Longitudinal Study on Aging (CLSA) follow-up 1 survey to analyze dental insurance and last oral health care visit. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the association between socioeconomic, psychosocial, and physical measures with access to oral care, measured by dental insurance and last oral health visit. RESULTS: Among the 44,011 adults included in the study, 40% reported not having dental insurance while 15% had not visited an oral health professional in the previous 12 months. Several factors were identified as barriers to accessing oral health care including, no dental insurance, low household income, rural residence, and having no natural teeth. People with an annual income of <$50,000 were four times more likely to not have dental insurance (adjusted OR: 4.09; 95% CI: 3.80-4.39) and three times more likely to report not visiting an oral health professional in the previous 12 months (adjusted OR: 3.07; 95% CI: 2.74-3.44) compared to those with annual income greater than $100,000. CONCLUSIONS: Identifying barriers to oral health care is important when developing public health strategies to improve access, however, further research is needed to identify the mechanisms as to why these barriers exist.

Given the recent increase in e-cigarette use among adolescents, there is a need to further explore how school programs are associated with e-cigarette initiation. The objective of this quasi-experimental study was to evaluate the impact of multiple school-based e-cigarette prevention and cessation programs on e-cigarette initiation among Canadian adolescents. This study used data from Year 6 (2017/18) and Year 7 (2018/19) of the COMPASS study in British Columbia, Alberta, Ontario, and Quebec, Canada. Students in grades 9 to 11 who had never tried e-cigarettes at baseline were included (n = 13,269). Schools (n = 88) reported whether they added programming that addressed e-cigarette or tobacco prevention or cessation. Generalized estimating equations were used to identify how added programs were associated with e-cigarette initiation at follow-up. At one-year follow-up (2018/19), 23% of schools added programs. Our evaluation results suggest that none of the activities taken by schools to prevent or reduce vaping among students significantly prevented vaping onset. In fact, female students at schools that reported adding a theme week had higher odds of e-cigarette initiation (OR 1.68 [95% CI 1.31-2.16]) and male students at schools that reported a cessation program had higher odds of e-cigarette initiation (OR 1.20 [95% CI 1.01-1.44]). These results suggest that schools may not know how to address e-cigarette use and that there can be risks to students if programs are not carefully implemented. Results point to the need for additional support to ensure that schools are taking evidence-based approaches that support all students.

BACKGROUND: The COVID-19 pandemic disrupted access to healthcare services in Canada. Research prior to the pandemic has found that depression and anxiety symptoms were associated with increased unmet healthcare needs. The primary objective of this study was to examine if mental health was associated with perceived access to healthcare during the pandemic METHODS: A cross-sectional study was conducted using data from 23,972 participants (aged 50-96) in the Canadian Longitudinal Study on Aging COVID-19 Exit Survey (Sept-Dec 2020). We used logistic regression to estimate how the presence of depression and anxiety symptoms, defined using scores of ≥10 on the Center for Epidemiologic Studies Depression Scale and ≥10 on the Generalized Anxiety Disorder Scale, were associated with the odds of reporting: 1) challenges accessing healthcare, 2) not going to a hospital or seeing a doctor when needed, 3) experiencing barriers to COVID-19 testing. Models were adjusted for sex, age, region, urban/rural residence, racial background, immigrant status, income, marital status, work status, chronic conditions, and pre-pandemic unmet needs. RESULTS: The presence of depressive (aOR=1.96; 95% CI=1.82, 2.11) and anxiety symptoms (aOR=2.33; 95% CI=2.04, 2.66) compared to the absence of these symptoms were independently associated with higher odds of challenges accessing healthcare. A statistically significant interaction with sex suggested stronger associations in females with anxiety. Symptoms of depression (aOR=2.88; 95% CI=2.58, 3.21) and anxiety (aOR=3.05; 95% CI=2.58, 3.60) were also associated with increased odds of not going to a hospital or seeing a doctor when needed. Lastly, depressive (aOR=1.99; 95% CI=1.71, 2.31) and anxiety symptoms (aOR=2.01; 95% CI=1.58, 2.56) were associated with higher odds of reporting barriers to COVID-19 testing. There was no significantly significant interaction with sex for the latter two outcomes. CONCLUSION: The presence of depression and anxiety symptoms were strongly associated with perceived unmet healthcare needs during the COVID-19 pandemic. Interventions to improve healthcare access for adults with depression and anxiety during the pandemic may be necessary.

Background: Historically substance use literature has focused on smoking as the main mode of cannabis consumption, so there are knowledge gaps surrounding current understanding of edibles and vaping. These alternative modes of cannabis use are already common among Canadian youth; however, little is known about how these cannabis use patterns change over time. Methods: This study examined the mode (smoking, eating/drinking, vaping) and frequency of cannabis use among a large sample of Canadian youth who participated in 2017-2018 and 2018-2019 data collection waves of the COMPASS study. Using latent transition analysis, this sample consisting of 18,824 youth in grades 9-12 were categorized into cannabis use classes stratified by sex, and their transition between these classes over the one-year period was examined. Results: Three cannabis use classes were identified (occasional multimode, regular multimode, and smoking) alongside one nonuse class. Among youth who reported cannabis use at baseline, transitioning to a multimode group, and/or increasing frequency of multimode use was likely over the one-year period. Conclusions: These findings may highlight a key leverage point for harm-reduction strategies which aim to prevent cannabis related harms associated with high frequency use.

BACKGROUND: There is an association between sports participation and substance use. However, there is some evidence that intramural sports in high school may not have the same effect. Therefore, the objective of this research was to examine the longitudinal associations between intramural participation in high school and substance use. Methods: This study used a three-year linked sample (2016-2018) of grade 9 and 10 (ages 13-17) Canadian high school students in the COMPASS (Cannabis use, Obesity, Mental health, Physical activity, Alcohol use, Smoking, Sedentary behavior) study (n = 7,845). Students reported their participation in intramurals over time (consistent, none, initiate, intermittent, and quit) and their substance use behaviors (binge drinking, cannabis use, cigarette use, and e-cigarette use). Mixed effects models were used. Results: 42% of students did not participate in intramurals. For binge drinking, male students who never participated had lower odds (0.66 [0.47-0.93]) compared to consistent intramural participators. Female (3.50 [CI: 1.34-9.16]) and male students (1.97 [1.28-3.02]) who did not participate in any intramurals were more likely to use cannabis than consistent participators. Male students who did not participate were also more likely to use cigarettes (1.81 [1.05-3.12]). No associations were found between intramural participation and e-cigarette use. Conclusion: Intramural participation may be associated with increased binge drinking among male high school students. More promisingly, consistent participation in intramurals may be protective against cannabis use among male and female students and cigarette use among male students.

Reducing youth cannabis use in Canada is a public health priority with schools of interest as a potential modifier of behavior and as a venue for prevention programming. This work aimed to provide a basis for future policy and programming by evaluating pre-legalization cannabis use change patterns in schools and the impact of school characteristics on these patterns. Average rates of cannabis use behavior change (initiation, escalation, reduction, cessation) were collected from 88 high schools located in Ontario and Alberta, Canada participating in the COMPASS prospective cohort study. There was little variability in cannabis use behaviors between schools with intra-class correlation coefficients lowest for cessation (0.02) and escalation (0.02) followed by initiation (0.03) and reduction (0.05). Modest differences were found based on school province, urbanicity and student-peer use. Cannabis ease of access rates had no significant effect. Fewer than half the schools reported offering school drug use prevention programs; these were not significantly associated with student cannabis use behaviors. In conclusion, current school-based cannabis prevention efforts do not appear sufficiently effective. Comprehensive implementation of universal prevention programs may reduce cannabis harms. Some factors (urbanicity, peer use rates) may indicate which schools to prioritize.

BACKGROUND: The Strengths and Difficulties Questionnaire (SDQ) is a brief measure of children's and adolescents' mental health. There are different versions of the questionnaire: a version for children and adolescents to complete by self-reporting, a version for parents and guardians to complete ("parent-rated"), and a version for teachers to complete. The purpose of this study was to examine the psychometric properties of the parent-rated SDQ with a nationally representative sample of Canadian children and adolescents. DATA AND METHODS: Data are from cycle 1 (2007 to 2009), cycle 2 (2009 to 2011), cycle 3 (2012 to 2013) and cycle 4 (2014 to 2015) of the Canadian Health Measures Survey. Data include 7,451 Canadian children and adolescents aged 6 to 17 years (49.3% female). Parents and guardians completed the SDQ by reflecting on their child's behaviour over the past six months. Factorial validity was examined via confirmatory factor analysis, which included testing the original five-factor SDQ model and alternative three-factor and higher-order models. Reliability was assessed through composite reliability scores. Measurement invariance across subgroups was also assessed. RESULTS: The original five-factor (i.e., emotional symptoms, conduct problems, peer problems, hyperactivity and prosocial behaviour) SDQ fit the data satisfactorily, demonstrated evidence of reliability, and was invariant across sex (male vs. female), age (children vs. adolescents) and survey language (English vs. French). The higher-order solution fit the data acceptably, and the three-factor solution did not fit the data well. DISCUSSION: The original five-factor, parent-rated SDQ demonstrates evidence of factorial validity and reliability as a population measure of mental health difficulties among Canadian children and adolescents.

Dysglycemia, including prediabetes and type 2 diabetes, is dangerous and widespread. Yet, the condition is transiently reversible and sequelae preventable, prompting the use of prediction algorithms to quickly assess dysglycemia status through self-reported data. However, as current algorithms have largely been developed in older populations, their application to younger adults is uncertain considering associations between risk factors and dysglycemia vary by age. We sought to identify sex-specific predictors of current dysglycemia among young adults and evaluate their ability to screen for prediabetes and undiagnosed diabetes. We analyzed 2005-2014 data from the National Health and Nutrition Examination Survey for 3251 participants aged 20-39, who completed an oral glucose tolerance test (OGTT), had not been diagnosed with diabetes, and, for females, were not pregnant. Sex-specific stepwise logistic models were fit with predictors identified from univariate analyses. Risk scores were developed using adjusted odds ratios and model performance was assessed using area under the curve (AUC) measures. The OGTT identified 906 (27.9%) and 78 (2.4%) participants with prediabetes or undiagnosed diabetes, respectively. Predictors of dysglycemia status for males were BMI, age, race, and first-degree family history of diabetes, and, in addition to those, education, delivered baby weight, waist circumference, and vigorous physical activity for females. Our male- and female-specific models demonstrated improved validity to assess dysglycemia presence among young adults relative to the widely-used American Diabetes Association test (AUCâ¯=â¯0.69 vs. 0.61; 0.92 vs. 0.71, respectively). Thus, age-specific scoring algorithms employing questionnaire data show promise and are effective in identifying dysglycemia among young adults.

To examine the prevalence of folate inadequacy and toxicity based on usual intakes from food and supplements, as well as biomarkers of folate, secondary data analyses were performed using cross-sectional, nationally representative data from the Canadian Community Health Survey, Cycle 2.2 (n 32 776), as well as biomarker data from the Canadian Health Measures Survey, Cycles 1, 2 and 3 (n 15 754). On the basis of unfortified food sources, Canadians would struggle to consume adequate amounts of folate. When folate intakes from all food sources were considered, the overall prevalence of folate inadequacy was low across all age/sex groups, with the exception of females >70 years. However, >10 % of supplement users were above the tolerable upper intake level, increasing to almost 18 % when overage factors were accounted for. In addition, between 20 and 52 % of supplement users had elevated erythrocyte folate concentrations, depending on the cut-off used. Results from this study suggest that insufficient dietary intakes of folate in Canadians have been ameliorated because of the fortification policy, although folate inadequacy still exists across all age groups. However, supplement users appear to be at an increased risk of folic acid (FA) overconsumption as well as elevated erythrocyte folate. As such, the general population should be informed of the potential risks of FA overconsumption resulting from supplement use. This study suggests a need for more careful assessment of the risks and benefits of food fortification, particularly fortification above mandated levels, and FA supplement use in the general population.

PURPOSE: This study examines the association between intake of selected macronutrients and the risk of stomach cancer in a Northern American population. METHODS: Mailed questionnaires were completed between 1994 and 1997 in eight Canadian provinces by 1,181 incident, histologically confirmed cases of stomach cancer and 5,039 population controls. Information on nutrient intake was obtained using a food frequency questionnaire. Odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) were derived through unconditional logistic regression to adjust for potential confounders, including an estimate of total energy intake. RESULTS: Intakes of total fat, saturated fat, and cholesterol were significantly associated with the risk of stomach cancer: The ORs for the highest versus the lowest quartile were 1.58 (95% CI 1.13-2.20), 1.86 (95% CI 1.37-2.52), and 1.75 (95% CI 1.36-2.25), respectively. Total fiber was inversely associated with stomach cancer (p = 0.03). The positive associations with intake of total fat and saturated fat were apparently stronger in women, overweight or obese subjects, and ever smokers. Saturated fat was specifically associated with increased risk of gastric cardia cancer, with an OR of 3.31 (95% CI 1.48-7.43). CONCLUSIONS: A diet high in saturated fat appears to increase the risk of stomach cancer, particularly among obese subjects and for gastric cardia cancer.

OBJECTIVES: The objectives of this study were 1) to examine and compare changes in functional limitations during the COVID-19 pandemic among older adults with and without diabetes; and 2): to identify key risk factors associated with developing functional limitations among older adults with and without diabetes during the pandemic. METHODS: We analyzed data collected from the Canadian Longitudinal Study on Aging. The analysis was restricted to those with no functional limitations in the follow-up 1 wave (2015 to 2018) (final sample N=6,045). Regression models were used to describe associations between diabetes status and functional limitation outcomes. We conducted stratified analyses to evaluate whether these associations varied by sociodemographic indicators. We also predicted the probability of the development of ≥1 functional limitation among those with and without diabetes for various patient profiles. RESULTS: Older adults with diabetes were 1.28-fold (95% confidence interval 1.02 to 1.60) more likely to develop ≥1 functional limitation than older adults without diabetes after controlling for relevant sociodemographic and health covariates. Risk factors for incident functional limitations among older adults, both with and without diabetes, include increasing age, low socioeconomic status, obesity, multimorbidity, and physical inactivity. CONCLUSIONS: Our findings indicate that older adults with diabetes were at an increased risk of developing functional limitations during the pandemic when compared with older adults without diabetes, even when controlling for several key risk factors. Targetting modifiable risk factors, such as physical activity, may help to reduce the risk of functional limitations among older adults with diabetes.

INTRODUCTION: Research characterizing substance use disparities between gender minority youth (GMY) and non-GMY (i.e. girls and boys) is limited. The aim of this study was to examine the differences in substance use behaviours among gender identity (GI) groups and identify associated risk and protective factors. METHODS: Cross-sectional data from Canadian secondary school students (n = 42 107) that participated in Year 8 (2019/20) or Year 9 (2020/21) of the COMPASS study were used. Hierarchal logistic regression models estimated current substance use (cigarettes, e-cigarettes, binge drinking, cannabis and nonmedical prescription opioids [NMPOs]). Predictor variables included sociodemographics, other substances, mental health outcomes, school connectedness, bullying and happy home life. Interaction terms were used to test mental health measures as moderators in the association between GI and substance use. RESULTS: Compared to non-GMY, GMY reported a higher prevalence for all substance use outcomes. In the adjusted analyses, GMY had higher odds of cigarette, cannabis and NMPO use and lower odds for e-cigarette use relative to non-GMY. The likelihood of using any given substance was higher among individuals who were involved with other substances. School connectedness and happy home life had a protective effect for all substances except binge drinking. Bullying victimization was associated with greater odds of cigarette, e-cigarette use and NMPOs. Significant interactions between GI and all mental health measures were detected. CONCLUSION: Findings highlight the importance of collecting a GI measure in youth population surveys and prioritizing GMY in substance use-related prevention, treatment and harm reduction programs. Future studies should investigate the effects of GI status on substance use onset and progression among Canadian adolescents over time.

Global industries and technological advancements have contributed to the proliferation of fast food (FF) establishments and ultraprocessed food, associated with poorer diet quality and health outcomes. To investigate FF as an indicator, we compared alternative methods to capture self-reported FF consumption and examined associated socio-demographic factors. We conducted a secondary analysis of the 2014-2015 Foodbook study, a cross-sectional survey on foods consumed by Canadians during the previous week. An embedded randomized design compared alternative FF intake questions of varying details. A total of 6062 participants aged 18+ were included, representing 24.7 million Canadian adults. Approximately 48% consumed FF in the past week, and of FF consumers, average frequency was twice. Asking broadly about FF intake without examples resulted in significantly lower reported FF intake compared with the two more detailed questions; the latter two were not significantly different. Burgers, pizza, and submarines/sandwiches were most commonly consumed. Men, younger age, higher BMI, women in central Canada (versus territorial regions), and men with income $30 000-$80 000 (versus >$80 000) were associated with higher FF consumption. Consumption of FF is common among Canadians; some associated factors are gender-specific. Further research examining FF as an indicator, and individual and societal implications of FF consumption, is recommended to inform programs and policies.

OBJECTIVES: (1) In a subsample of older adults with asthma without a history of depression, to determine the factors associated with developing depression during the COVID-19 pandemic; (2) in a subsample of older adults with asthma with a history of depression, to identify factors associated with recurrent depression during the pandemic. METHODS: Data came from four waves (Baseline [2011-2015], Follow-up 1 [2015-2018]; COVID Spring 2020, COVID Autumn 2020) of the Canadian Longitudinal Study on Aging's comprehensive cohort (n = 2,047 with asthma). The outcome of interest was a positive screen for depression based on the CES-D-10 during the autumn of 2020. Bivariate and multivariate logistic regression analyses were conducted. RESULTS: Among older adults with asthma without a history of depression (n = 1,247), approximately 1 in 7 (13.5%) developed depression for the first time during the COVID-19 pandemic. Among those with a history of depression (n = 770), approximately 1 in 2 (48.6%) experienced a recurrence of depression. The risk of incident depression and recurrent depression was higher among those who were lonely, those experiencing family conflict during the pandemic, and those who had difficulty accessing healthcare resources during the pandemic. The risk of incident depression only was higher among those who had difficulty accessing resources and/or loss of income during the pandemic. The risk of recurrent depression only was higher among those with functional limitations. CONCLUSIONS: There is a need for targeted interventions to support the mental health of older adults with asthma who have the above identified vulnerabilities during the pandemic.

Purpose: The objectives of this study were to identify the prevalence of, and factors associated with, incident and recurrent depression in a sample of older adults with a history of cancer during the COVID-19 pandemic. Materials and Methods: Data were drawn from four waves of the Canadian Longitudinal Study on Aging Comprehensive Cohort (n=2486 with cancer). The outcome of interest was a positive screen for depression based on the CES-D-10 during the autumn of 2020. Results: Among older adults with cancer and no pre-pandemic history of depression (n=1765), 1 in 8 developed first onset depression during the pandemic. Among respondents with cancer and a history of depression (n=721), 1 in 2 experienced a recurrence of depression. The risk of both incident and recurrent depression was higher among those who were lonely, those with functional limitations, and those who experienced an increase in family conflict during the pandemic. The risk of incident depression only was higher among older women, those who did not engage in church or religious activities, those who experienced a loss of income during the pandemic, and those who became ill or had a loved one become ill or die during the pandemic. The risk of recurrent depression only was higher among those who felt isolated from others and those whose income did not satisfy their basic needs. Conclusion: Health care providers should continue to screen and provide mental health support to their cancer patients and those with a lifetime history of cancer, with consideration for those with the aforementioned vulnerabilities.
RESUMO
The COVID-19 pandemic and associated public health measures have exacerbated many known risk factors for depression that may be particularly concerning for individuals with chronic health conditions, such as peptic ulcer disease (PUD). In a large longitudinal sample of older adults with PUD, the current study examined the incidence of depression during the pandemic among those without a pre-pandemic history of depression (n = 689) and the recurrence of depression among those with a history of depression (n = 451). Data came from four waves of the Canadian Longitudinal Study on Aging (CLSA). Multivariate logistic regression analyses were conducted to identify factors associated with incident and recurrent depression. Among older adults with PUD and without a history of depression, approximately 1 in 8 (13.0%) developed depression for the first time during the COVID-19 pandemic. Among those with a history of depression, approximately 1 in 2 (46.6%) experienced depression during the pandemic. The risk of incident depression and recurrent depression was higher among those who were lonely, those with functional limitations, and those who experienced an increase in family conflict during the pandemic. The risk of incident depression only was higher among women, individuals whose income did not satisfy their basic needs, those who were themselves ill and/or those whose loved ones were ill or died during the pandemic, and those who had disruptions to healthcare access during the pandemic. The risk of recurrent depression only was higher among those with chronic pain and those who had difficulty accessing medication during the pandemic. Implications for interventions are discussed.
