"It depends on the boss" - a qualitative study of multi-level interventions aiming at office workers' movement behaviour and mental health.

PURPOSE: This embedded qualitative study explored the acceptability, feasibility, and fidelity of two multi-level RCT interventions among office workers, aiming at improving movement behaviour to enhance mental health and cognition. The interventions addressed the organizational, environmental, and individual level. METHODS: Semi-structured interviews and focus group discussions were conducted with 38 stakeholders after completion of the interventions. Data were analysed using reflexive thematic analysis. RESULTS: The interventions were well appreciated, and office workers attributed improvements in movement behaviour and wellbeing to the interventions. Especially the cognitive behavioural therapy (CBT) based counselling and free gym access were appreciated, feasible and delivered as planned. Participants described existing workplace norms as barriers to more activity, particularly for reducing sitting. Support from managers and team support were considered crucial components. However, delivering these components was difficult. CONCLUSIONS: The findings support the design of the multi-level interventions for changing movement behaviour. Results highlight the potential of CBT for this target group and the importance of manager and team support. Desired effects of similar multi-level interventions, including CBT, might be achieved in future studies that carefully address the issues with feasibility and acceptability and the resulting low fidelity of some intervention components that were identified in this study.

Associations between the School Environment and Physical Activity Pattern during School Time in Swedish Adolescents.

Knowledge about associations between school-based initiatives and physical activity patterns is limited. The purpose of this paper was to examine associations between factors in the school environment, physical activity and sedentary time during school time. The cross-sectional study included 1139 adolescents aged 13-14 from 34 schools. Physical activity and sedentary time were measured using hip-worn accelerometers. Factors in the school environment included health policy, a mobile phone ban during breaks, organized physical activities during breaks and activity breaks during lessons reported by teachers. The frequency and duration of breaks and physical education (PE) lessons were collected from school schedules. The results showed significant associations between health policy (ß = 3.87, 95% confidence interval (CI): 2.37, 5.23), the mobile phone ban (ß = 2.51, 95% CI: 1.29, 3.94) and PE; total duration (ß = 0.08, 95% CI: 0.05, 0.11), average duration (ß = 0.08, 95% CI: 0.01, 0.13) and frequency (ß = 1.73, 95% CI: 0.50, 3.04) and moderate-vigorous physical activity. There were negative associations between health policy (ß = -6.41, 95% CI: -10.24, -2.67), the mobile phone ban (ß = -3.75, 95% CI: -7.25, -0.77) and PE; total duration (ß = -0.15, 95% CI: -0.23, -0.08) and average duration (ß = -0.14, 95% CI: -0.27, -0.03) and time spent sedentary. Adolescents attending schools with health policies, mobile phone bans and more time for PE showed higher levels of physical activity and lower sedentary time.
