Neighbourhood walkability and greenspace and their associations with health-related fitness in urban dwelling Canadian adults
The researchers aimed to outline sex-specific associations between the neighborhood built environment, grip strength, and body fat percentage of Canadian adults living in urban areas. They used cohort data from 4,052 males and 7,841 females who were part of Alberta’s Tomorrow Project. Negative associations were found between walkability and both grip strength and body fat percentage among males and females. Additionally, greenness showed a positive association with grip strength across both sexes, but this association was not observed with body fat percentage. These associations remained significant even after adjusting for physical activity and sitting.
Polygenic inheritance and its interplay with smoking history in predicting lung cancer diagnosis: a French-Canadian casecontrol cohort
The researchers equipped a case-control dataset, consisting of 4002 lung cancer cases from the LORD project and 20,010 ethnically matched controls from the CARTaGENE cohort. The researchers aimed to generate a genome-wide polygenic risk score for lung cancer to improve risk prediction and delineate individuals at high genetic risk of lung cancer for earlier detection and prevention.
The mediating role of health behaviors in the association between depression, anxiety and cancer incidence: An individual participant data meta-analysis
Researchers investigated how various health behaviors might mediate the relationships between depression, anxiety, and the onset of different types of cancer. They conducted individual participant data meta-analyses using participants from 18 cohorts from the Psychosocial Factors and Cancer Incidence consortium.The cohorts analyzed included the Atlantic Partnership for Tomorrow’s Health, Ontario Health Study, and CARTaGENE. The findings suggested that smoking serves as a mediating factor that connects depression and anxiety with lung cancer and other cancers related to smoking.
Oral microbial signatures associated with age and frailty in Canadian adults
The researchers investigated the relationship between the oral microbiome, age, and frailty using data from Atlantic PATH cohort participants. Analyzing saliva samples from 1,357 individuals aged 35–70, they found that frailty was inversely associated with most alpha diversity measures, while age was positively associated with Shannon Diversity and Evenness. These findings suggest that the oral microbiome may be a valuable marker of frailty risk and a potential target for health interventions in aging adults.
The association between religiosity, spirituality and colorectal cancer screening: a longitudinal analysis of Alberta’s Tomorrow Project in Canada
The researchers performed a longitudinal analysis regarding associations between religion/spirituality (RS) Salience, and R/S Attendance, and colorectal cancer screening. The data of 4312 participants aged ≥ 50 from Alberta’s Tomorrow Project was used for this study. After completing statistical analyses, the researchers determined a significant association between R/S Attendance and colorectal cancer screening. However, R/S Salience did not contribute to higher odds of colorectal cancer screening, as the association was not statistically significant. The authors of the study propose the implementation of colorectal cancer screening programs in R/S settings.
Predictors of primary cutaneous melanoma stage at diagnosis: observations from Alberta’s Tomorrow Project
This study examined data from the Alberta’s Tomorrow Project on 62 adults who developed primary cutaneous melanoma by 2018. The majority (67.74%) were diagnosed at stage I, with individual factors like being married or common-law, having an annual household income between $50,000–100,000, and spending more than 1 hour in the sun between 11 am–4 pm per day during the past summer. In contrast, increased occupational physical activity was linked to a higher likelihood of later-stage diagnosis. These findings highlight potential epidemiologic risk factors that could inform targeted interventions for earlier melanoma detection.
Differences in antihypertensive medication prescription profiles between 2009 and 2021: a retrospective cohort study of CARTaGENE
Researchers examined the differences in antihypertensive medication prescription profiles in the province of Quebec between 2009 and 2021. Data from the CARTaGENE population–based cohort was used. The study found that application of hypertension guidelines for the choice of antihypertensive drugs remains suboptimal, underscoring the importance of educational initiatives.
Stage shifting by modifying the determinants of breast cancer stage at diagnosis: a simulation study
The researchers sought to understand how lifestyle factors influence the stage at which breast cancer is diagnosed. Using data from 492 participants in Alberta’s Tomorrow Project, they found that increasing dietary protein intake and reducing energy intake had the most significant impact. This suggests that minor lifestyle adjustments could potentially increase the rate of early-stage diagnoses by 12%, thereby informing cancer prevention strategies.
Dose-responsive effects of iron supplementation on the gut microbiota in middle-aged women
The researchers sought to investigate the association between iron supplementation and the gut microbiota among healthy female participants in Alberta’s Tomorrow Project. They found that adequate iron levels are essential for the overall health and wellbeing of women through their various life stages.
Age- and sex-specific associations of frailty with mortality and healthcare utilization in community-dwelling adults from Ontario, Canada
The researchers sought to estimate the association of frailty with the risk of death, hospital admissions, and length of hospital stay. Using data from the Ontario Health Study linked to all-cause mortality and hospital admissions data from ICES, they found that frailty is an important health construct for both younger and older adults.
