Age differences in perceived environmental supports and barriers highlight the need to address age-related disparities to improve walkability. Future research should consider the relationship between perceived and objective built environment features and their impact on physical activity.

The CNQOM is the first online questionnaire in Canada designed to capture perspectives and attitudes towards specific elements of SCSs and ORHAs among diverse key informant groups. Our questionnaire was administered to a large, geographically diverse sample and designed to capture the perspectives of four key informant groups. Lower than expected test–retest reliability may be explained by lack of participant familiarity with SCS and especially ORHAs and the impersonal nature of the instrument content among some respondents. Future work will elucidate key informant perspectives on these services based on the data.

This study examined the reliability and validity of single-item self-reported HRF measures of aerobic fitness, muscular strength and endurance, flexibility, coordination, agility, and body composition, finding that the MHFS provides a reliable and valid HRF indicator among younger adult populations.
