Dietary patterns with combined and site-specific cancer incidence in Alberta’s Tomorrow Project cohort

Authors: Romy Willemsen, Jessica McNeil, Emily Heer, Steven Johnson, Christine Fredenreich, Darren Brenner

This study used data from the Alberta’s Tomorrow Project to examine the association between dietary patterns derived with two methods, and combined and site-specific cancer incidence in Canada.

Associations between neighbourhood built characteristics and sedentary behaviours among Canadian men and women: findings from Alberta’s Tomorrow Project

Authors: Vikram Nichani, Liam Turley, Jennifer E. Vena, Gavin R. McCormack

This study examined associations between the objective neighbourhood built environment and self-reported sedentary behaviour. Researchers sourced data from 14,785 Alberta’s Tomorrow Project participants. 3-way intersections, high population counts, and high walkability resulted in more sitting time, and low connectivity and low walkability resulted in more sitting time in motor vehicles.

The effect of different methods to identify, and scenarios used to address energy intake misestimation on dietary patterns derived by cluster analysis

Authors: Geraldine Lo Siou, Alianu Akawung, Nathan Solbak, Kathryn McDonald, Ala Al Rajabi, Heather Whelan, Sharon Kirkpatrick

This study used self-reported food frequency and physical activity data from Alberta’s Tomorrow Project participants to compare the revised-Goldberg and the predicted total energy expenditure methods in their ability to identify misreporters of energy intake.

Towards refining World Cancer Research Fund/American Institute for Cancer Research cancer prevention recommendations for red and processed meat intake: insights from Alberta’s Tomorrow Project cohort

Authors: Ala Al Rajabi, Geraldine Lo Siou, Alianu K. Akawung, Kathryn McDonald, Tiffany R. Price, Grace Shen-Tu, Paula J. Robson, Paul J. Veugelers, Katerina Maximova

This study examined the associations of processed meat derived from red versus non-red meats with cancer risk in the Alberta’s Tomorrow Project cohort of 26 218 adults who reported dietary intake using the Canadian Diet History Questionnaire. Incidence of cancer was obtained through data linkage with the Alberta Cancer Registry.

A longitudinal residential relocation study of changes in street layout and physical activity

Researchers sourced data from 5,944 Alberta’s Tomorrow Project participants to estimate physical activity differences between non-movers and movers – those moving to neighbourhoods with less or more integrated street layouts. They found that moving to more integrated areas led to more leisure walking and more moderate- and vigorous-intensity physical activity.

A Prospective Analysis of Plasma Phospholipid Fatty Acids and Breast Cancer Risk in 2 Provinces in Canada

Authors: Marnie Newell, Sunita Ghosh, Susan Goruk, Mohammedreza Pakseresht, Jennifer Vena, Trevor Dummer, Catherine Field

This study compared participants from BCGP and ATP and examined whether there was an association between fatty acid status and the risk of breast cancer, including location, menopausal status, and waist-to-hip ratio as key variables. Findings suggest that regional variations in fatty acid status influence breast cancer risk and highlights the complexity and difficulty in using fatty acid status to predict breast cancer risk in diverse populations without the consideration of other risk factors.

Administering a combination of online dietary assessment tools, the Automated Self-Administered 24-Hour Dietary Assessment Tool and Diet History Questionnaire-II, in a cohort of adults in Alberta’s Tomorrow Project

Authors: Nathan Solbak, Paula Robson, Geraldine Lo Siou, Ala Al Rajabi, Seol Paek, Jennifer Vena, Sharon Kirkpatrick

This study determined the feasibility and acceptability of combining the ASA24-2016 and the past-year Diet History Questionnaire web-based tools in a subset of participants in the ATP cohort. The study found that combining ASA24-2016 recalls and the DHQ-II is feasible in this group of ATP participants.

Normal sex and age-specific parameters in a multi-ethnic population: a cardiovascular magnetic resonance study of the Canadian Alliance for Healthy Hearts and Minds cohort

Authors: Judy M. Luu, Catherine Gebhard, Chinthanie Ramasundarahettige, Dipika Desai, Karleen Schulze, Francois Marcotte, Philip Awadalla, Philippe Broet, Trevor Dummer, Jason Hicks, Eric Larose, Alan Moody, Eric E. Smith, Jean-Claude Tardif, Tiago Teixeira, Koon K. Teo, Jennifer Vena, Douglas S. Lee, Sonia S. Anand, Matthias G. Friedrich

Researchers sought to create a robust, reference value set for cardiovascular magnetic resonance (CMR) parameters, and understand their relationship with age and sex in people without cardiovascular disease (CVD) history or risk factors. They were able to uncover a significant influence of sex and age on these parameters for use in clinical evaluations of CVD.

Social Jetlag and Prostate Cancer Incidence in Alberta’s Tomorrow Project: A Prospective Cohort Study

Authors: Liang Hu, Andrew Harper, Emily Heer, Jessica McNeil, Chao Cao, Yikyung Park, Kevin Martell, Geoffrey Gotto, Grace Shen-Tu, Cheryl Peters, Darren Brenner, Lin Yang

Social jetlag has been linked with obesity, metabolic disorders, and cardiovascular risk in previous research. This study assessed social jetlag in 7455 cancer-free men in Alberta’s Tomorrow Project and followed them for on average 9.6 years, 250 men were diagnosed with prostate cancer. The study found that the more social jetlag men experienced, the greater their prostate cancer risk was.

The Importance of Cancer Registry Linkage for Studying Rare Cancers in Prospective Cohorts

Authors: Emily Maplethorpe, Emily V. Walker, Trenton Smith, Faith G. Davis, Yan Yuan

This research study evaluated the validity of self-reported cancer diagnosis in ATP by linking to the Alberta Cancer Registry. The first instance of self-reported cancer in a follow-up survey was compared to the first cancer diagnosis in the ACR after enrollment. The study found that rare cancers were less likely to be captured by active follow-up than common cancers.
