Abstract Background Interventions that work must be effectively delivered at scale to achieve population level benefits. Researchers choose among a vast array of implementation frameworks (> 60) guide design and evaluation scale-up processes. Therefore, we sought recommend conceptual can used design, inform, evaluate physical activity (PA) nutrition interventions different stages the program life cycle. We also minimum data set outcome determinant variables (indicators) as well measures...
Background The Carrot Rewards app was developed as part of an innovative public-private partnership to reward Canadians with loyalty points, exchangeable for retail goods, travel rewards, and groceries engaging in healthy behaviors such walking. Objective This study examined whether a multicomponent intervention including goal setting, graded tasks, biofeedback, very small incentives tied daily step achievement (assessed by built-in smartphone accelerometers) could increase physical activity...
Despite known health benefits of physical activity (PA), older adults remain among the least physically active age group globally with 30-60% not meeting guidelines. In Canada, 87% do meet recommended To influence population health, interventions that are effective in small trials must be disseminated at scale. evidence for efficacy, few PA scaled up to reach wider community. 2015, British Columbia (BC) Ministry Health released a strategy where were identified as priority. partnership...
ABSTRACT BACKGROUND We examined longitudinal changes in children's physical activity during the school day, afterschool, and evening across fifth, sixth, seventh grades. METHODS The analytical sample included children who had valid accelerometer data fifth grade at least one other time‐point, provided complete sociodemographic information (N = 768, 751, 612 for 3 time‐periods studied). Accelerometer‐derived total ( TPA ) moderate‐to‐vigorous MVPA were expressed minutes per hour day (∼7:45 am...
Despite the many known benefits of physical activity (PA), relatively few older adults are active on a regular basis. Older adult PA interventions delivered in controlled settings showed promising results. However, to achieve population level health impact, programs must be effectively scaled-up, and have achieved this. To scale-up it is essential identify contextual factors that facilitate or impede implementation at scale. Our aim describe influence scale promotion intervention for (Choose...
Abstract Background Top tier commercial physical activity apps rarely undergo peer-reviewed evaluation. Even fewer are assessed beyond six months, the theoretical threshold for behaviour maintenance. The purpose of this study was to examine whether a multi-component app rewarding users with digital incentives walking associated an increase in over one year. Methods This 12-month quasi-experimental conducted two Canadian provinces ( n = 39,113 participants). Following two-week baseline...
Purpose: The primary objective of this study was to examine whether exergames could help children reach the recommendations for PA and cardiorespiratory fitness regarding exercise intensity. Differences in perceived physical exertion, EE, VO2, HR between normal weight (NW) overweight (OW) participating were also examined. Methods: Twenty-one (age: 10.45 ± 0.88) assessed VO2 during rest, a maximal treadmill test, while playing different exergames. Ratings exertion (RPE) (category range: 0 10)...
This study examined associations of various elements the home environment with after-school physical activity and sedentary time in 671 6th-grade children (Mage = 11.49 ± 0.5 years). Children's total activity, moderate-to-vigorous were measured by accelerometry. Parents completed surveys assessing social environment. Mixed-model regression analyses used to examine between each element children's time. Availability resources was associated positively negatively boys. Parental support MVPA...
The purpose of this pilot study was to evaluate the feasibility and effectiveness an intervention that employed a technology-based physical activity (PA) monitoring system teacher-regulated strategies promote PA in preschoolers. A total 93 preschoolers (53% girls, 4.7 years) from 5 child care centers were recruited for one-week randomly assigned into control (2 centers, n = 45) or (3 48) group. Key components included: (1) wearable device-based, real-time children's by classroom teachers (2)...
To examine temporal variations in parental and peer influences on adolescent physical activity (PA) whether these predicted changes PA.We analyzed data from Years 1, 2 3 of the COMPASS study. Participants were 22 909 students Grades 9 to 12 (mean age [years] = 15.42 ± 1.12, 46% boys, 85% White), who had completed following survey items or more consecutive occasions: age, sex, grade, race/ethnicity, moderate-to-vigorous (MVPA), encouragement instrumental support for PA, number active peers....
ABSTRACT Little is known about the factors that influence implementation of physical activity interventions undertaken in youth-serving settings, and this lack information impedes development effective strategies. This study convened a panel experts to identify are most important achieving successful organizations. Five recognized participated four-round, modified Delphi consensus process. The panelists were asked achieve on list potential predicting descriptions these factors. They also...
Evaluation of acceptability and preliminary efficacy an Internet short message service (SMS) intervention for promoting physical activity (PA) in Hong Kong Chinese school children. An 8-week quasi-experimental study non-randomly assigned 78 children (mean age=12.8 years) to (a) group that received a stage-matched, PA program two times week tailored SMS messages daily; or (b) no-treatment control. Data were collected from September 2008 until June 2009. Acceptability measures included...
Abstract Background Virtual data collection methods and consent procedures adopted in response to the COVID-19 pandemic enabled continued research activities, but also introduced concerns about equity, inclusivity, representation, privacy. Recent studies have explored these issues from institutional researcher perspectives, there is a need explore patient perspectives preferences. This study aims patients’ recruitment for COVID-19. Methods We conducted an exploratory qualitative focus group...
Adverse drug events (ADEs) are a leading cause of unplanned hospital visits. We designed ActionADE, an online ADE reporting platform, and integrated it with PharmaNet, British Columbia's (BC's) provincial medication dispensing system, to overcome identified barriers in communicate ADEs community pharmacies. Our objectives were characterise reported explore associations between patients' age, sex characteristics, estimate the re-dispensation rate culprit medications conducted prospective...
To examine the effects of short messaging service (SMS) frequency and timing on efficacy an SMS-intervention for Hong Kong Chinese adolescents, sixty nine students aged between 12 16 (mean age 13.75 ± 0.90) were recruited from five schools in Kong. Participants randomly assigned into one groups: high-frequency + self-selected (HST), low-frequency (LST), (HAT), (LAT) control group. The total duration intervention was four weeks. No significant detected adolescent's PA among groups (F = 1.14,...
In 2017, the provincial government of British Columbia (BC) implemented a mandatory policy outlining Active Play Standards (AP Standards) to increase physical activity (PA) levels, sedentary and motor skills among children attending licensed childcare centers. Concurrently, capacity-building initiative was launched help implement policies practices supporting both PA healthy eating (HE) in early years. This study evaluated differences center-level HE before after enforcement new AP...
