Associations between neighbourhood street connectivity and sedentary behaviours in Canadian adults: Findings from Alberta’s Tomorrow Project

Authors: Vikram Nichani, Mohammad Javad Koohsari, Koichiro Oka, Tomoki Nakaya, Ai Shibata, Kaori Ishii, Akitomo Yasunaga, Jennifer E Vena, Gavin R McCormack

Researchers aimed to estimate associations between street connectivity, based on space syntax-derived street integration, and sedentary behaviours. Using data from 14,758 Alberta’s Tomorrow Project participants, they found that connectivity was positively related to various measures of sitting time and negatively associated with motor vehicle travel time.

Cross-sectional and longitudinal associations between the built environment and walking: effect modification by socioeconomic status

Authors: Chelsea D Christie, Christine M Friedenreich, Jennifer E Vena, Liam Turley, Gavin R McCormack

Using data from 703 Alberta’s Tomorrow Project participants, researchers found that changes to the built environment are not associated with changes in walking amongst adults after relocation. They also had weak findings that changes in walkability due to relocation may more strongly affect walking for adults with lower socioeconomic status.

A dietary carbohydrate – gut Parasutterella – human fatty acid biosynthesis metabolic axis in obesity and type 2 diabetes

Authors: Lea Henneke, Kristina Schlicht, Nadia A. Andreani, Tim Hollstein, Tobias Demetrowitsch, Carina Knappe, Katharina Hartmann, Julia Jensen-Kroll, Nathalie Rohmann, Daniela Pohlschneider, Corinna Geisler, Dominik M. Schulte, Ute Settgast, Kathrin Türk, Johannes Zimmermann, Christoph Kaleta, John F. Baines, Jane Shearer, Shrushti Shah, Grace Shen-Tu, Karin Schwarz, Andre Franke, Stefan Schreiber, Matthias Laudes

This study aimed to characterize Parasutterella, a gut bacteria, in a European cohort. 438 participants from Alberta’s Tomorrow Project were included to validate the results of this study. Researchers found that this bacteria have a role in type 2 diabetes and obesity.

Health-Related and Behavioral Factors Associated With Lung Cancer Stage at Diagnosis: Observations From Alberta’s Tomorrow Project

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

This study examined sociodemographic characteristics and health-related factors and their associations with subsequent lung cancer stage at diagnosis. Using data from 221 Alberta’s Tomorrow Project participants, researchers found that a history of sunburn in the past year and more prostate-specific antigen tests were protective against late-stage lung cancer diagnosis, whereas physical activity increased late-stage cancer diagnosis odds.

Pre-diagnosis lifestyle, health history and psychosocial factors associated with stage at breast cancer diagnosis – Potential targets to shift stage earlier

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

This study aimed to examine associations between risk factors for breast cancer diagnosis, prior to and and at diagnosis. Some protective factors include older age at diagnosis, high household income, parity, smoking, spending time in the sun (high ultraviolet), having a mammogram, and high daily protein intake. Factors that increase risk of later stage at diagnosis include comorbidities, stressful situations, and high daily caloric intake.

Lifestyle factors and lung cancer risk among never smokers in the Canadian Partnership for Tomorrow’s Health (CanPath)

Authors: Rachel Murphy, Maryam Darvishian, Jia Qi, Yixian Chen, Quincy Chu, Jennifer Vena, Trevor J B Dummer, Nhu Le, Ellen Sweeney, Vanessa DeClercq, Scott A Grandy, Melanie R Keats, Yunsong Cui, Philip Awadalla, Darren R Brenner, Parveen Bhatti

Data from 950 CanPath participants were analyzed to understand why 15-25% of lung cancers occur in never smokers. Researchers found a link between lung cancer risk, sleep, and fruit and vegetable intake amongst never smokers.

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.

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.
