Implementing a Public Bicycle Share Program: Impact on Perceptions and Support for Public Policies for Active Transportation

Ariane Bélanger-Gravel, Lise Gauvin, Daniel Fuller, and Louis Drouin

Background:

Favorable public opinion and support for policies are essential to favor the sustainability of environmental interventions. This study examined public perceptions and support for active living policies associated with implementing a public bicycle share program (PBSP).

Methods:

Two cross-sectional population-based telephone surveys were conducted in 2009 and 2010 among 5011 adults in Montréal, Canada. Difference-in-differences analyses tested the impact of the PBSP on negative perceptions of the impact of the PBSP on the image of the city, road safety, ease of traveling, active transportation, health, and resistance to policies.

Results:

People living closer to docking stations were less likely to have negative perceptions of the effect of the PBSP on the image of the city (OR = 0.5; 95% CI, 0.4−0.8) and to be resistant to policies (OR = 0.8; 95% CI, 0.6−1.0). The likelihood of perceiving negative effects on road safety increased across time (OR = 1.4; 95% CI, 1.2−1.8). Significant interactions were observed for perceptions of ease of traveling (OR = 0.5; 95% CI, 0.4−0.8), active transportation (OR = 0.6; 95% CI, 0.4−1.0), and health (OR = 0.6; 95% CI, 0.4−0.8): likelihood of negative perceptions decreased across time among people exposed.

Conclusion:

Findings indicate that negative perceptions were more likely to abate among those living closer to the PBSP.

Self-Rated Health and Mortality in Canada

Caitlin Mason, Peter T. Katzmarzyk, Cora L. Craig, and Lise Gauvin

Background:

This study investigates the degree to which the relationship between self-rated health and mortality is consistent across income groups in Canada and whether it can be explained by differentials in physical activity.

Methods:

A sample of 17,852 adults in the 1981 Canada Fitness Survey was followed for 13 y for mortality.

Results:

After adjusting for several confounders, there was a dose-response relationship between self-rated health and all-cause, CVD, and cancer mortality. This relationship persisted across levels of income. Physical activity was inversely related to mortality; however, the risk of mortality associated with low self-rated health did not differ significantly between activity groups.

Conclusions:

Physical activity does not appear to be a significant mediating or moderating factor in the relationship between self-rated health and mortality.

Modifying Effects of Sex, Age, and Education on 22-Year Trajectory of Leisure-Time Physical Activity in a Canadian Cohort

Tracie A. Barnett, Lise Gauvin, Cora L. Craig, and Peter T. Katzmarzyk

Background:

We investigated the population trajectory of leisure time physical activity (LTPA) in adults age 18 to 60 y (n = 881), who were recruited in 1981 for the Canada Fitness Survey and followed-up through the Campbell’s Survey on Well-Being (1988) and the Physical Activity Longitudinal Study (2002/04).

Methods:

Data on involvement in LTPA were collected by questionnaire and used to estimate average daily energy expenditure (EE) (kcal · kg-1 · d-1) during leisure time. Growth trajectory modeling was used to describe the overall population trajectory of LTPA and the extent to which average trajectories varied between sub-groups defined by age, sex, and education.

Results:

The population trajectory of LTPA over time was modified by baseline age, but not by sex or by level of education. Disparities in LTPA related to sex and education persisted over two decades.

Conclusion:

This longitudinal investigation improves our understanding of the processes underlying patterns of LTPA in adults.

Towards a Social Epidemiological Perspective on Physical Activity and Health: The Aims, Design, and Methods of the Physical Activity Longitudinal Study (PALS)

Cora Lynn Craig, Lise Gauvin, Sue Cragg, Peter T. Katzmarzyk, Thomas Stephens, Storm J. Russell, Lloyd Bentz, and Louise Potvin

Background:

The health benefits of physical activity are substantial; however, the lifetime and environmental determinants of sedentary living are poorly understood. The purpose of this article is to outline the conceptual background and methods of the Physical Activity Longitudinal Study (PALS), a follow-up study of a population- and place-based cohort. A secondary purpose is to report on the success of follow-up procedures.

Methods:

A rationale for conducting a 20-y follow-up of a nationally representative population- and place-based cohort is developed based on the extant literature dealing with socio-environmental determinants of health and on current advancements in thinking about the determinants of involvement in physical activity. Then, methods of the 2002-04 PALS (n = 2511, nonresponse = 29.8%) that began with the 1981 Canada Fitness Survey are described. Descriptive data pertaining to the success of follow-up procedures are outlined.

Results:

There is general consensus around the relevance of examining lifetime and environmental determinants of physical activity involvement. Longitudinal data represent one source of information for disentangling the relative importance of these determinants. Examination of PALS follow-up data show that there was no selection bias for key individual- (physical activity, other lifestyle, health) and area-level (median income, housing) variables, although fewer respondents than nonrespondents smoked or were underweight at baseline. Some demographic groups were under- or over-represented among the eligible cohort, but not among participants.

Conclusions:

The social epidemiological perspective emerging from PALS should help policymakers and public health practitioners make strides in changing socio-environmental factors to curb sedentary lifestyles and promote population health.
