Evaluation of Adiposity and Cognitive Function in Adults

Authors: Sonia S. Anand, Matthias G. Friedrich, Douglas S. Lee, Phillip Awadalla, J. P. Després, Dipika Desai, Russell J. de Souza, Trevor Dummer, Grace Parraga, Eric Larose, Scott A. Lear, Koon K. Teo, Paul Poirier, Karleen M. Schulze, Dorota Szczesniak, Jean-Claude Tardif, Jennifer Vena, Katarzyna Zatonska, Salim Yusuf, Eric E. Smith, the Canadian Alliance of Healthy Hearts and Minds (CAHHM), the Prospective Urban and Rural Epidemiological (PURE) Study Investigators

Researchers sought to undercover the association between adipose tissue (amount and distribution) and cognitive scores. Using data from 9,189 participants, they found that higher visceral adipose tissue and body fat percentage correlated with increased vascular brain injuries and cardiovascular risk factors, as well as lower cognitive scores.

Predictors of CRC Stage at Diagnosis among Male and Female Adults Participating in a Prospective Cohort Study: Findings from Alberta’s Tomorrow Project

Authors: Monica Ghebrial, Michelle L. Aktary, Qinggang Wang, John J. Spinelli, Lorraine Shack, Paula J. Robson, Karen A. Kopciuk

This study aimed to uncover factors associated with colorectal cancer (CRC) at diagnosis in 267 Alberta Tomorrow Project participants. Researchers found that social support, having children, and caffeine intake were strong CRC stage predictors at diagnosis for males. In contrast, CRC family history, pregnancy, hysterectomy, menopausal hormone therapy, Pap test lifetime number, and household physical activity were strong CRC predictors at diagnosis for females.

The impact of reporting magnetic resonance imaging incidental findings in the Canadian alliance for healthy hearts and minds cohort

Authors: Judy M. Luu, Anand K. Sergeant, Sonia S. Anand, Dipika Desai, Karleen Schulze, Bartha M. Knoppers, Ma’n H. Zawati, Eric E. Smith, Alan R. Moody, Sandra E. Black, Eric Larose, Francois Marcotte, Erika Kleiderman, Jean-Claude Tardif, Douglas S. Lee, Matthias G. Friedrich on behalf of the CAHHM Study Investigators

This study aimed to describe the management policy for incidental findings (IFs) for the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort and understand IF disclosure effects for participants. IF management is challenging, though results are promising for the CAHHM’s policies since 97% of participants with an IF reported no change in their quality of life.

Two approaches for estimating propensity score weights for examining neighbourhood built environment and walking changes

Authors: Chelsea Christie, Jennifer Vena, Christine Friedenreich, Gavin McCormack

Christie et al. created a walkability index using pre- and post-relocation neighbourhood built environment and walking data from Alberta’s Tomorrow Project participants to examine how walking duration changed with residential relocation. While changes in walkability were not associated with changes in walking, the researchers suggest further research regarding neighbourhood environment changes and other physical activity behaviours.

Examining the etiology of early-onset breast cancer in the Canadian Partnership for Tomorrow’s Health (CanPath)

Authors: Joy Pader, Robert Basmadjian, Dylan O'Sullivan, Nicole Mealey, Yibing Ruan, Christine Friedenreich, Rachel Murphy, Edwin Wang, May Lynn Quan, Darren Brenner

The objective of this study was to investigate relationships between modifiable and non-modifiable risk factors and early-onset breast cancer among the BC Generations Project, Alberta’s Tomorrow Project and Ontario Health Study. In this study, measures of adiposity, pregnancy history, and familial history of breast cancer are important risk factors for early-onset breast cancer.

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.

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.

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.
