Exploring physical activity knowledge, attitudes, and health behaviours among medical students
BACKGROUND: Physical inactivity is a major public health concern, yet many physicians feel underprepared to counsel patients on physical activity (PA). Despite national recommendations to integrate PA education into medical curricula, implementation remains inconsistent. This study investigates the knowledge, attitudes, and behaviours related to PA among medical students at the University of British Columbia (UBC), which offers the most extensive…
Who thrives in Canada? An Examination of social factors, healthcare access, and immigration status
High-income countries like Canada report some of the worlds’ highest life-satisfaction levels, yet less is known about how life satisfaction varies by race and immigration status. This study investigates the factors that influence subjective well-being among 8,063 adults from the Canadian Alliance of Healthy Hearts and Minds study recruited between 2014 and 2018, including a subset of 2,142 immigrants. Measures of demographic, socioeconomic, heal…

Creation of a rough runnability index using an affordance-based framework
Running is one of the most popular forms of physical activity. To date, no literature explores association between the features of the built environment and running. A limited amount of literature uses walkability as a proxy for runnability, thereby misjudging the differing goals of walking and running: leisure, sport or commute. We create a rough runnability index using an affordance-based framework as a conceptual and methodological attempt to …
Neighborhood Characteristics Associated with Running in Metro Vancouver
Running can improve physical health and psychological wellbeing. However, the characteristics of conducive running environments are relatively unknown. This study determines neighborhood factors that attract running and explores how age and gender mediate built environment preferences. Spatial patterns of runners in Metro Vancouver were identified using crowdsourced fitness data from Strava, a popular application for tracking physical activities.…
Developing indicators of age-friendly neighbourhood environments for urban and rural communities across 20 low-, middle-, and high-income countries
This study indicates the extent to which environmental supports for healthy ageing may be less readily available to older adults residing in rural areas and LMIC and augments calls to tailor WHO's existing indicators to a broader range of communities in order to achieve a critical aspect of distributional equity in an ageing world
Neighborhood Greenspace and Socioeconomic Risk are Associated with Diabetes Risk at the Sub-neighborhood Scale
Greenspace and socioeconomic status are known correlates of diabetes prevalence, but their combined effects at the sub-neighborhood scale are not yet known. This study derives, maps, and validates a combined socioeconomic/greenspace index of individual-level diabetes risk at the sub-neighborhood scale, without the need for clinical measurements. In two Canadian cities (Vancouver and Hamilton), we computed 4 greenspace variables from satellite ima…
Relationship of parental feeding practices and diet with children's diet among South Asians in Canada
Obesity and Cardiovascular Disease
The global obesity epidemic is well established, with increases in obesity prevalence for most countries since the 1980s. Obesity contributes directly to incident cardiovascular risk factors, including dyslipidemia, type 2 diabetes, hypertension, and sleep disorders. Obesity also leads to the development of cardiovascular disease and cardiovascular disease mortality independently of other cardiovascular risk factors. More recent data highlight ab…

OBJECTIVE: To examine the association between social isolation and mortality and incident diseases in middle-aged adults in urban and rural communities from high-income, middle-income and low-income countries. DESIGN: Population-based prospective observational study. SETTING: Urban and rural communities in 20 high income, middle income and low income. PARTICIPANTS: 119 894 community-dwelling middle-aged adults. MAIN OUTCOME MEASURES: Associations…
Environmental Preferences and Concerns of Recreational Road Runners
Recreational road running is growing in popularity and has been linked to numerous mental and physical health benefits. However, we know little about what environmental preferences or concerns runners have regarding participation in the sport, and whether differences exist across age and gender. We conducted a cross-sectional survey on recreational road runners to investigate the type of built and natural environments road runners prefer, as well…
Psychological Impact of Covid-19 on People with Pre-Existing Chronic Disease
The COVID-19 pandemic has caused an increase in anxiety and depression levels across broad populations. While anyone can be infected by the virus, the presence of certain chronic diseases has been shown to exacerbate the severity of the infection. There is a likelihood that knowledge of this information may lead to negative psychological impacts among people with chronic illness. We hypothesized that the pandemic has resulted in increased levels …

Availability and affordability of medicines and cardiovascular outcomes in 21 high-income, middle-income and low-income countries
OBJECTIVES: We aimed to examine the relationship between access to medicine for cardiovascular disease (CVD) and major adverse cardiovascular events (MACEs) among people at high risk of CVD in high-income countries (HICs), upper and lower middle-income countries (UMICs, LMICs) and low-income countries (LICs) participating in the Prospective Urban Rural Epidemiology (PURE) study. METHODS: We defined high CVD risk as the presence of any of the foll…
The household economic burden of non-communicable diseases in 18 countries
Background: Non-communicable diseases (NCDs) are the leading cause of death globally. In 2014, the United Nations committed to reducing premature mortality from NCDs, including by reducing the burden of healthcare costs. Since 2014, the Prospective Urban and Rural Epidemiology (PURE) Study has been collecting health expenditure data from households with NCDs in 18 countries. Methods: Using data from the PURE Study, we estimated risk of catastroph…
Relationship between diet and acculturation among South Asian children living in Canada
Socioeconomic status and risk of cardiovascular disease in 20 low-income, middle-income, and high-income countries
Background Socioeconomic status is associated with differences in risk factors for cardiovascular disease incidence and outcomes, including mortality. However, it is unclear whether the associations between cardiovascular disease and common measures of socioeconomic status—wealth and education—differ among high-income, middle-income, and low-income countries, and, if so, why these differences exist. We explored the association between education a…

Suburbanisation of oral cavity cancers
While the aging of suburban populations provides some explanation of these trends, we highlight the role of the suburbanisation of socioeconomically deprived and Asia-born populations, known to have higher rates of risk behaviours such as tobacco, alcohol, and betel/areca consumption. Specifically, betel/areca consumption among Asia-born populations is suspected to be a primary driver of the observed geographical shift in incidence from urban cor…
Availability, affordability, and consumption of fruits and vegetables in 18 countries across income levels
BACKGROUND: Several international guidelines recommend the consumption of two servings of fruits and three servings of vegetables per day, but their intake is thought to be low worldwide. We aimed to determine the extent to which such low intake is related to availability and affordability. METHODS: We assessed fruit and vegetable consumption using data from country-specific, validated semi-quantitative food frequency questionnaires in the Prospe…
