Background: Online platforms are increasingly used to deliver training and implementation resources for large-scale, school-based physical activity initiatives, and understanding behavioral engagement with these platforms is important because it provides an early indicator of initiative uptake; yet, few studies have examined engagement during real-world scale-up. Objective: This study examined school staff engagement with the website and its associated factors during the first 22 months of national scale-up in secondary schools. Methods: As part of an implementation trial, engagement metrics were obtained from the website (October 2023 through August 2025) using Google Analytics, and user and school characteristics were derived from registration data on the website and the Australia database. Engagement metrics were summarized descriptively (eg, number and frequency of pages accessed, time spent on pages, and content-specific metrics), and associations between staff- and school-level characteristics and engagement outcomes were examined using multivariable linear and logistic regression models. Results: A total of 200 secondary school staff from 6 Australian states and 2 territories registered for the website, of whom 110 were tracked by Google Analytics. Users included school leaders, physical education (PE) teachers, and non-PE teaching staff, with most users being female and working in government schools. Overall engagement was predominantly characterized by single-visit use, with a median of 1 (IQR 1-2) session, and approximately one-third of users accessed only the registration page. Across the study period, users viewed a median of 5 (IQR 2-9) pages and spent a median of 8.4 (IQR 5.2‐13.1) minutes on the website. Page reach was highest for general information and teaching resources pages. Compared with schools in Victoria, engagement duration was longer in the Northern Territory (β=2.98 min; =.01) and South Australia (β=4.05 min; =.01), while schools with high student-teacher ratios had shorter engagement than those with low student-teacher ratios (β=–3.11 min; =.01). Compared with low-achieving schools, schools with medium academic achievement had greater odds of accessing implementation resources (odds ratio 4.74, 95% CI 1.26‐17.85; =.02). Conclusions: Engagement with the website during secondary school national scale-up reflected the opportunistic and self-directed nature of engagement with online initiatives in real-world settings. Dissemination during scale-up should not end when users receive the materials but should also ensure meaningful engagement with web-based resources. Future research should measure more meaningful dimensions of engagement and examine school- and user-level factors to better understand determinants of engagement and inform scale-up strategies.

**Study Links Prolonged Sitting to Increased Cardiovascular Risk** A new study has established a correlation between extended periods of sedentary behavior and an elevated risk of cardiovascular ailments. Researchers from the National Institute of Health analyzed data collected over ten years, involving approximately 500,000 adults aged 30 to 79. The findings, released on August 19,

A study published in BMC Medicine reveals that replacing daily exercise with sedentary behaviours like sitting or watching TV significantly elevates cancer risk. Researchers analysed data from 59,218 UK Biobank participants aged 61.7 on average, tracking their activity levels over eight years. The findings indicate that even minor reductions in physical activity—such as substituting 15 minutes of movement with sleep or sedentary behaviour—correlate with a 2% increased cancer risk. Conversely, replacing 30 minutes of exercise with inactivity raises the risk by 8%. Dr John Mitchell from University College London warns that even losing two to three minutes daily of vigorous activity, like running for a bus, could heighten cancer susceptibility. The study underscores the importance of maintaining active lifestyles, particularly as people age, and highlights the NHS guidelines recommending at least 150 minutes of moderate exercise weekly. Key insights include the direct link between movement levels and cancer risk reduction, with specific examples of activities that elevate heart rate and promote health.
