Background: Obesity disproportionately impacts men's health yet fewer men engage in preventive healthcare. We examined the effectiveness of Hockey Fans in Training (Hockey FIT), a gender-sensitised lifestyle intervention that engages men with overweight/obesity through their passion as fans of a local sports team, on weight change and other health indicators.

Methods: Pragmatic, cluster randomised trial (aged 35-65 years, body mass index ≥ 27 kg/m) within 42 community-based sites in Canada and the United States, randomly assigned (1:1) to intervention (Hockey FIT) or control (wait-list) and stratified by region.

Background: Children's physical inactivity is a persisting international public health concern. While there is a large body of literature examining physical activity interventions for children, the unique physical activity context of low-density communities in rural areas and smaller urban centres remains largely underexplored. With an influx of families migrating to rural communities and small towns, evaluations of health promotion efforts that support physical activity are needed to ensure they are meeting the needs of the growing populations in these settings.

The COVID-19 pandemic has negatively impacted the mental health and wellbeing of post-secondary students. Resilience has been found to serve as a protective factor against mental distress among students during the pandemic. Despite the plethora of research that exists on post-secondary students during this crisis, most studies exploring students' health and resilience are quantitative and lack diversity.

Background: Early childhood educators play a critical role in promoting physical activity and reducing sedentary time in childcare centres. However, early childhood educators receive limited specialised pre- and in-service learning opportunities relating to these behaviours and may lack the capacity to effectively engage children in healthy movement behaviours. This study aimed to examine the efficacy of an e-Learning course on increasing early childhood educators' physical activity and sedentary behaviour-related capacities.

Resilience, or the ability to bounce back despite facing adversities, may influence parents' abilities to handle the multitude of parent-specific COVID-19-related challenges that have faced them. This cross-sectional study examined (1) the relationship between parents' resilience and their COVID-19-related family stressors; (2) parents' perceptions of their greatest stressors throughout the pandemic; and (3) non-school-related challenges and their resultant impact on parents' and children's resilience. Via an online survey, data was collected from 63 parents (M = 37.

This interpretive description study explored coping among older women in Ontario experiencing intimate partner violence (IPV) during COVID-19. Twelve in-depth interviews with older women found age-related normative beliefs played a role in how older women viewed their lives and how they looked beyond their experiences of IPV. Their roles as caretakers and homemakers influenced their response to IPV, and COVID-19 exacerbated feelings of lost time and loneliness.

The COVID-19 pandemic has provided a collective opportunity to engage in prosocial behaviours, including kindness; however, little is known about the long-term impacts of the pandemic on such behaviours. As a part of a larger study (Health Outcomes for Adults During and Following the COVID-19 Pandemic), the purpose of this mixed methods research was two-fold: (1) to quantitatively explore adults' prosocial behaviour over time during the first 16 months of the pandemic in Ontario, Canada (April 2020-August 2021); and, (2) to more deeply explore, via focus groups, a sub-sample of Ontario adults' lived experiences of prosocial behaviour (assessed March 2022). A total of 2,188 participants were included in this study, with the majority of participants identifying as female (89.

Little is known about how wake-time movement behaviour compositions while in childcare relate to children's health and development. This study aimed to use compositional analysis to examine how childcare movement behaviour compositions were associated with standardised body mass index (BMI) and physical and psychosocial functioning among children in the preschool setting. A total of 405 preschoolers wore accelerometers during childcare hours to measure their moderate-to-vigorous physical activity (MVPA), light intensity physical activity (LPA) and sedentary time.

Smartphone ownership and engagement are at an all-time high. Excessive smartphone use may impart smartphone-specific anxiety; specifically, the fear of being unable to access or use one's smartphone, or nomophobia. Young adults, in particular, are at higher risk for nomophobia, given higher ownership of and engagement with smartphones.

The COVID-19 pandemic and resultant public health measures, although helpful in reducing the spread of the disease, have disproportionately impacted women experiencing intimate partner violence (IPV). Despite these adverse circumstances, women continue to show resilience. Although difficult to define, resilience can be conceptualized as a dynamic process in which psychosocial and environmental factors interact to enable an individual to survive, grow, and thrive despite exposure to adversity.

Background: This study aimed to: (a) explore differences in the prevalence of nomophobia and smartphone addiction (SA) from pre- to during COVID-19; (b) identify students' self-reported changes in smartphone reliance and screen time during COVID-19; and (c) examine whether self-perceived changes in smartphone usage predicted nomophobia and SA scores.

Methods: Scores on the Nomophobia Questionnaire and Smartphone Addiction Scale between two surveys administered at two timepoints were compared: Sample 1 (September 2019-January 2020;  = 878) and Sample 2 (May-June 2020;  = 258).

Results: No significant differences were found between samples on nomophobia or SA.
