Design Feasibility multicentre, parallel group, randomised controlled trial (RCT). Setting Participants were recruited from England and Canada using a d...

Objectives Self-compassion involves being caring and kind to oneself rather than self-judging during setbacks or in the face of shortcomings. Reflective writing through journaling is a simple intervention strategy that may promote self-compassion. However, the majority of reflective writing studies have examined relatively transient changes in self...

Background E-learning can be an effective and efficient mode of training healthcare practitioners. E-learning training for diabetes prevention program coaches was designed and developed with input from end users. Insight from those who deliver the training and coaches who have taken the training can provide critical feedback for further refinement...

Background Collecting demographic data is critical for identifying inequities in healthcare services and delivery. Inaccurate collection of demographic data can make developing equitable health interventions and improving reach of existing interventions difficult. This study aimed to (a) examine experiences in completing a community-based type 2 di...

Background Public health nutrition recommendations and clinical dietary interventions emphasize eating healthy food at home, implicitly requiring household foodwork. Household foodwork is defined as the physical and mental tasks a household does for eating meals and snacks. Because no tools exist to measure it, how much time people spend doing hous...

Equity, diversity, and inclusion (EDI) gaps persist in science, technology, engineering, and math (STEM) fields, as demonstrated by the discrimination, stereotyping, and inequities that historically and persistently marginalized groups face. Recognition of this gap led a transdisciplinary team to develop foundational-level e-learning modules, title...

Debate over whether to promote high-intensity interval training (HIIT) in public-health contexts has centred on assumptions that people will have negative psychological responses to HIIT, leading to poor adoption and adherence. We challenge these assumptions through reviews of (1) studies that have measured psychological responses to HIIT and (2) s...

Background Technology is more likely to be used when it is designed to meet the needs of end users. To supplement the Small Steps for Big Changes diabetes prevention program, a smartphone app was developed in partnership with past Small Steps for Big Changes clientele.

Background To determine rates of compliance (i.e., supervised intervention attendance) and adherence (i.e., unsupervised physical activity completion) to high-intensity interval training (HIIT) among insufficiently active adults and adults with a medical condition, and determine whether compliance and adherence rates were different between HIIT and...

Physical activity is a beneficial, yet complex, health behavior. To ensure more people experience the benefits of physical activity, we develop and test interventions to promote physical activity and its associated benefits. Nevertheless, we continue to see certain groups of people who choose not to, or are unable to, take part in research, resulti...

In-task affective responses to moderate-intensity continuous exercise training (MICT) have been shown to predict future physical activity behavior. However, limited research has investigated whether this affect–behavior relationship is similar for high-intensity interval training (HIIT) and whether it holds true over the longer term. This study aim...

In the workplace, people are often sedentary for prolonged time and do not regularly engage in physical activity—two factors independently linked to premature morbidity and mortality. This study aimed to determine the receptivity of incorporating practical stair-climbing “exercise snacks” (Snacks; three isolated bouts of ascending 53–60 stairs perf...

Social determinants of health, the effects of colonialism, and systemic injustices result in some groups being at disproportionately higher risk for developing type 2 diabetes (T2D). Many T2D prevention programs have not been designed to provide equitable and inclusive care to everyone. This paper presents an example of the steps taken in an eviden...

Background Seventy-five per cent of individuals with prediabetes will eventually be diagnosed with type 2 diabetes. Physical activity is a cornerstone in reducing type 2 diabetes risk but can be a challenging behaviour to adopt for those living with prediabetes. Individuals with prediabetes experience difficult emotions associated with being at ris...

Self-monitoring applications (apps) are being increasingly integrated into diabetes prevention programs; however, more research is needed to understand how individuals engage with self-monitoring apps, what leads to sustained use, and whether these apps translate to improved physical activity over time. This brief report explored (1) participant en...

Sprint interval training (SIT) is characterized by intensity of “all-out” effort and superior time-efficiency compared to traditional moderate-intensity continuous training (MICT) and has been proposed as one viable solution to address the commonly reported barrier of lack of time for physical activity. While substantial physiological benefits of p...

Background Despite numerous translations of diabetes prevention programs, implementation evaluations are rarely conducted.

Lay Summary Making changes to one’s physical activity and diet can reduce future risk of developing type 2 diabetes. That being said, making life-long changes to complex behaviors such as diet or physical activity is easier said than done. Text messages can be used to improve long-term diet and physical activity changes; however, it can be difficul...

Translating evidence-based diabetes prevention programs into the community is needed to make promising interventions accessible to individuals at-risk of type 2 diabetes. To increase the likelihood of successful translation, implementation evaluations should be conducted to understand program outcomes and provide feedback for future scale-up sites....

Objectives Approximately 25% of Canadian children aged 4-8 years fail to meet the recommended dietary allowance (RDA) of calcium. Young children’s food choices are primarily determined by their parents. No interventions have directly targeted parents as a medium through which to increase children’s calcium consumption. This study compared the effec...

Background: Mobile health (mHealth) prompts (e.g., text messaging, push notifications) are a commonly used technique within behaviour change interventions to prompt or cue a specific behaviour. Such prompts are being increasingly integrated into diabetes prevention programs (DPPs). While mHealth prompts provide a convenient and cost-effective way...

Objectives Engagement in regular physical activity (PA) is a cornerstone prevention strategy for individuals at risk of developing type 2 diabetes. Interventions targeting PA often fail to result in long-term behaviour changes. “Small Steps for Big Changes” is a 3-week diabetes prevention program that promotes PA behaviour changes in individuals wi...

Background The risk of developing type 2 diabetes (T2D) can be reduced through diet and exercise changes. Given the rapidly increasing prevalence of T2D and the associated burden on the health-care system, there is a need for affordable and scalable diet and exercise programs to be delivered in communities. Small Steps for Big Changes (SSBC) is an...

Introduction Global rates of type 2 diabetes (T2D) are on the rise and there is a need for both effective and replicable interventions to decrease this incidence. Systematic reviews highlight the efficacy of diet and exercise interventions in decreasing T2D risk; however, no review to date provides clear information regarding intervention details (...

Purpose: To report pilot test findings on whether in-task affect during a supervised exercise program, where participants were randomized to either moderate-intensity continuous training (MICT) or high-intensity interval training (HIIT), predicts changes in moderate-to-vigorous physical activity (MVPA-Total and MVPA10+ in bouts of ≥ 10 min) at 1- a...

More than 350 million people are living with prediabetes. Preventing type 2 diabetes (T2D) progression can reduce morbidity, mortality and health-care costs.

Background: Both high-intensity interval training and moderate-intensity continuous training demonstrate beneficial physiological outcomes for active and insufficiently active populations. However, it remains unclear whether compliance to exercise in supervised settings translates to long-term adherence to physical activity in real-world, unstruct...

Background: Free-living adherence to high-intensity interval training (HIIT) has not been adequately tested. This randomized trial examined changes in cardiorespiratory fitness (CRF) and accelerometer-measured purposeful physical activity over 12 months of free-living HIIT versus moderate-intensity continuous training (MICT). Methods: Ninety-nin...

Interventions involving exercise and diet can reduce the progression of Type 2 diabetes, yet they are often short-lived. Progressing toward self-managed maintenance is also challenging. If supports are in place to help individuals with behavior changes beyond immediate programming, they are more likely to maintain these changes. This is particularl...

Translation of efficacious health interventions into the community are often not applied in practice. The gap between research and practice is concerning for community members who can benefit from early access to effective health interventions. Knowledge translation activities and strong community partnerships are demonstrated methods to close the...
