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).


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.


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.


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

Background: Evidence regarding the impact of physical activity (PA) communication campaigns among children is scarce. This study was aimed at examining the reach of the WIXX campaign and its impact on children’s PA beliefs and behaviors. Methods: This study adopted a pre–posttest design. Children (9–13 y old) were recruited using a random digit dialing procedure. Self-reported outcomes included PA beliefs, trying new PAs, and meeting PA guidelines. WIXX awareness and survey periods were the treatment variables. Logistic regression analyses were conducted to examine the main effect of treatment variables and the time-specific impact of WIXX. Results: The campaign reached 80.3% of the children. Fully adjusted results showed that girls with high (odd ratio = 1.4; 95% confidence interval, 1.0–2.0) and moderate (odd ratio = 1.4; 95% confidence interval, 1.0–1.8) awareness were more likely to have tried new PAs. Results from the sensitivity analyses suggested that this positive result was due to strategies implemented during the second year of the campaign. No other significant association between exposure and outcomes was observed. Conclusions: The WIXX campaign was successful in reaching a significant proportion of children. Although some encouraging results were observed among girls, WIXX awareness was not associated with changes on the examined outcomes among boys.
