Age and Sex-Specific Associations in Health Risk Factors for Chronic Disease: Evidence from the Atlantic Partnership for Tomorrow’s Health (PATH) Cohort

Title: Age and Sex-Specific Associations in Health Risk Factors for Chronic Disease: Evidence from the Atlantic Partnership for Tomorrow’s Health (PATH) Cohort Journal: Canadian Journal on Aging Authors: Vanessa DeClercq and Ellen Sweeney Abstract: The objective of this study was to discern health risk factors for chronic disease by age and sex in a Canadian cohort. Participants of the Atlantic Partnership for Tomorrow’s Health (PATH) cohort with health risk factor data (physical activity, smoking, alcohol consumption, diet, body mass index [BMI]) were included (n = 16,165). Multivariable logistic regression models were used to evaluate the relationship among health risk factors, age, and sex. Regression analysis revealed that the odds of engaging in high levels of physical activity and having a BMI ≥ 25 was lower for females than males across all age groups, whereas the odds of abdominal obesity was substantially higher for females of all ages than for males. The odds of habitually consuming alcohol was lower for females of all ages than for males, and the odds of being a former/current smoker was lower for older (57–74 years of age) females than for males. The odds of consuming five or more servings of fruit and vegetables per day was higher for females of all ages than for males. There are evident differences in health risk factors for males and for females, as well as across age groups, and public health efforts need to account for the role played by sex and age in addressing chronic disease burden in Canadian adults.

Shift Work and Mental Health: Findings from a new Atlantic PATH study

We are pleased to announce the latest in our research on Atlantic PATH shift workers! Sweeney et al. (2021) evaluated the relationship between mental health and shift work in a matched study with 12,413 participants, including 4155 shift workers and 8258 non-shift workers. Shift workers were more likely to have increased rates of depression and poor self-rated health, as well as depressive and anxiety symptom scores compared to non-shift workers. The full article can be found free for 50 days compliments of Elsevier – https://authors.elsevier.com/a/1dMIjKt2p%7EjIi This research builds on our previous work that found an increased risk of cardiovascular disease, obesity and diabetes among shift workers, despite higher levels of physical activity and lower levels of sedentary behaviour (https://bit.ly/2TJEoxN).    

The association between mental health and shift work: Findings from the Atlantic PATH study

Journal: Preventive Medicine Authors: Ellen Sweeney, Yunsong Cui, Zhijie Michael Yu, Trevor JB Dummer, Vanessa DeClercq, Cynthia Forbes, Scott A Grandy, Melanie R Keats, Anil Adisesh Abstract We evaluated the relationship between mental health and shift work in the Atlantic Partnership for Tomorrow’s Health (PATH) cohort study. In a matched study with 12,413 participants, including 4155 shift workers and 8258 non-shift workers, we utilized general linear models and logistic regression models to assess the differences in depression, anxiety, and self-rated health. Shift workers reported higher levels of each of the mental health-related domains compared to non-shift workers. There was a significant increased risk of depression (OR = 1.13, 95% CI, 1.00–1.27) and poor self-rated health (OR = 1.13, 95% CI, 1.14–1.55) among shift workers compared to non-shift workers. Shift workers were more likely to have increased rates of depression and poor self-rated health, as well as depressive and anxiety symptom scores compared to non-shift workers. As a result, shift workers may be at increased risk of comorbidity, poor quality of life, missed work, and early retirement.   Doi: https://doi.org/10.1016/j.ypmed.2021.106697

Early results from CanPath’s national study confirm antibody levels are stronger after receiving two doses of COVID-19 vaccine

Initial preliminary results from the Canadian Partnership for Tomorrow’s Health (CanPath) COVID-19 Antibody Study, based on close to 6,000 dried blood spot samples collected between February 8 and May 17, 2021, show a high degree of variability in the level of antibodies produced by a single dose of a COVID-19 vaccine. These findings highlight the importance of accelerating second doses as the Delta variant continues to spread, particularly with the vast majority of Canadians having received only a single vaccine dose. This is the first pan-Canadian study using samples from a wide range of participants to confirm evidence from vaccine manufacturers’ clinical trials, as well as findings in a recent preprint from the United Kingdom and other smaller studies.   Participants from Atlantic PATH, CARTaGENE, the Ontario Health Study, Manitoba Tomorrow Project, Alberta’s Tomorrow Project, and BC Generations contributed to the COVID-19 Antibody Study. https://bit.ly/3gVLeb2  

New Frontiers in Research Fund 2020 Exploration Grant

Atlantic PATH is thrilled to be involved in the newly funded project led by Dr. Juliet Daniel at McMaster University. The New Frontiers in Research Fund 2020 Exploration grants target high-risk, high-reward and interdisciplinary research. This work will focus on disparities in cancer incidence and outcomes in a Black Nova Scotian community (Shelburne, Nova Scotia). This research is truly interdisciplinary, incorporating natural and social sciences to consider the role of environmental, biological, genetic, socioeconomic, and lifestyle factors with the high cancer incidence and mortality in this community. We’re pleased to be working with our Dalhousie University colleagues, Dr. Ingrid Waldron (School of Nursing), Dr. Jong Sung Kim (Faculty of Medicine), Dr. Paola Marignani (Faculty of Medicine) and Dr. Charles Hostovsky (School of Planning).   https://bit.ly/3fHw3CU

Diabetes, Brain Infarcts, Cognition, and Small Vessels in the Canadian Alliance for Healthy Hearts and Minds Study

Journal: The Journal of Clinical Endocrinology & Metabolism Authors: Hertzel C Gerstein, Eric E Smith, Chinthanie Ramasundarahettige, Dipika Desai, Philip Awadalla, Philippe Broet, Sandra Black, Trevor J B Dummer, Jason Hicks, Alan Moody, Jean-Claude Tardif, Koon K Teo, Jennifer Vena, Salim Yusuf, Douglas S Lee, Matthias G Friedrich, Sonia S Anand Abstract: Background Diabetes is a risk factor for cerebrovascular disease and cognitive impairment. The anatomical basis for this is uncertain. Methods The Canadian Alliance for Healthy Hearts and Minds collected brain and carotid magnetic resonance imaging (MRI) and 2 cognitive tests (the Digit Symbol Substitution Test and the Montreal Cognitive Assessment test) in a cross-sectional sample of men and women. Brain MRIs identified brain infarcts (BI), lacunar BI, high white matter hyperintensity (WMH), vascular brain injury (VBI; BI or high WMH), and small vessel VBI (lacunar BI or high WMH). Carotid MRIs estimated carotid wall volume, a measure of subclinical atherosclerosis. Cognitive scores were standardized to each site’s mean score, and cognitive impairment was identified by 1 or both test scores ≤1 standard deviation below the site’s mean score on that test. Results The 7733 participants included 495 participants (6.4%) with diabetes, of whom 388 were taking diabetes drugs. After age and sex adjustment, diabetes was independently associated with BI (odds ratio [OR] 1.53, 95% confidence interval [CI] 1.05, 2.24), VBI (OR 1.64, 95% CI 1.26, 2.13), small vessel VBI (OR 1.67, 95% CI 1.28, 2.19), and cognitive impairment (OR 1.47, 95% CI 1.20, 1.80). The association between diabetes and small vessel VBI persisted after adjustment for cerebrovascular disease risk factors and nonlacunar infarcts (OR 1.52, 95% CI 1.15, 2.01), and the association with cognitive impairment persisted after adjustment for small vessel VBI (OR 1.27, 95% CI 1.03, 1.56). Conclusion Small vessel disease characterizes much of the relationship between diabetes and VBI. However, additional factors are required to disentangle the relationship between diabetes and cognitive impairment. Link: https://doi.org/10.1210/clinem/dgaa815
