Innovations in population intervention research capacity: the contributions of Canada on the Move.
The Canada on the Move project developed within a dynamic context and in response to an expressed need for increased capacity to support research involving population-level interventions. This article describes a) the movement to create an organized approach to chronic disease prevention in Canada, b) the emerging science of population-level intervention, c) the development of Canadian infrastructure to support population intervention science, and d) the contribution of Canada on the Move in developing a health research platform and, opportunistically, instigating a study which included assessment of the population impact of a commercial marketing initiative.

Evaluation of quality of commercial pedometers.
BACKGROUND: The purpose of this study was to: 1) evaluate the quality of promotional pedometers widely distributed through cereal boxes at the time of the 2004 Canada on the Move campaign; and 2) establish a battery of testing protocols to provide direction for future consensus on industry standards for pedometer quality. METHODS: Fifteen Kellogg's* Special K* Step Counters (K pedometers or K; manufactured for Kellogg Canada by Sasco, Inc.) and 9 Yamax pedometers (Yamax; Yamax Corporation, Tokyo, Japan) were tested with 9 participants accordingly: 1) 20 Step Test; 2) treadmill at 80m x min(-1) (3 miles x hr(-1)) and motor vehicle controlled conditions; and 3) 24-hour free-living conditions against an accelerometer criterion. RESULTS: Fifty-three percent of the K pedometers passed the 20 Step Test compared to 100% of the Yamax. Mean absolute percent error for the K during treadmill walking was 24.2+/-33.9 vs. 3.9+/-6.6% for the Yamax. The K detected 5.7-fold more non-steps compared to the Yamax during the motor vehicle condition. In the free-living condition, mean absolute percent error relative to the ActiGraph was 44.9+/-34.5% for the K vs. 19.5+/-21.2% for the Yamax. CONCLUSIONS: K pedometers are unacceptably inaccurate. We suggest that research grade pedometers: 1) be manufactured to a sensitivity threshold of 0.35 Gs; 2) detect +/-1 step error on the 20 Step Test (i.e., within 5%); 3) detect +/-1% error most of the time during treadmill walking at 80m x min(-1) (3 miles x hr(-1)); as well as, 4) detect steps/day within 10% of the ActiGraph at least 60% of the time, or be within 10% of the Yamax under free-living conditions.

Proximal impact of Canada on the Move: the relationship of campaign awareness to pedometer ownership and use.
OBJECTIVE: Despite increased participation in leisure-time physical activity, inactivity remains an important public health problem. This study examines the immediate impact of the Canada on the Move initiative to promote walking through pedometer use among adult Canadians. METHODS: Data from a rolling monthly sample were collected via the Canadian Fitness and Lifestyle Research Institute's Physical Activity Monitor between November 2003 and September 2004. Prevalence rates were compared using Bonferroni-adjusted confidence intervals. Correlates of campaign recall and pedometer ownership were estimated using odds ratios adjusted for age, sex, income and education. RESULTS: Message recall and awareness as well as ownership and use of pedometers increased over the campaign and coincided with promotional activity. There was some evidence of a dose response between the number of messages recalled and pedometer use. DISCUSSION: The increased awareness and usage of pedometers among adult Canadians is encouraging; it indicates that these proximal targets are realistic and achievable for health promotion campaigns and contribute to opportunities for increasing physical activity behaviours.

Characteristics of participants visiting the Canada on the move website.
BACKGROUND: The Internet is a potential medium to attain large groups of Canadians for physical activity monitoring and interventions, however, little is known about the characteristics of participants who could be recruited on a national level. Our objectives were to determine: 1) the extent to which our sample was representative of the Canadian population; 2) the demographic, social-cognitive and physical activity behaviour, and environmental characteristics of one-time and multi-time users of the Canada on the Move website; and 3) whether certain recruitment strategies were more likely to reach specific demographic subgroups. METHODS: Web-based self-report measures were collected on demographic, social-cognitive, physical activity behaviour, and environmental factors. Descriptive statistics were employed to address the study's research objectives. RESULTS: Significant differences (p<0.001) were found between our total sample and 2001 Canadian census/Canadian Community Health Survey (CCHS) data on all demographic and physical activity behaviour measures. One-time and multi-time users significantly differed on age (p<0.005) and being responsible for children under age 13 (p=0.01). No differences existed between the groups on any of the social-cognitive, behavioural or environmental variables. Source of knowledge about the Canada on the Move website between one-time and multi-time users was not significantly different. CONCLUSION: The Canada on the Move website presents a viable approach to reaching diverse demographic groups. Further work needs to be undertaken to: 1) develop engaging websites; 2) detail the monitoring of the web-based access information; 3) integrate the website with other organizations promoting physical activity; and 4) expand the number of recruitment sources.
