P08-07 The effects of an integrated approach to a worksite intervention on the mental health and wellbeing of cleaners: A randomized stepped wedge worksite study

Abstract Background Despite an intensive focus on worker health over the last three decades, the prevalence of work-related diseases remain largely unchanged in Denmark and internationally. In recent years, American and Australian researchers have developed new approaches to integrate health promotion, prevention of work-related disease and organization of work. The aim of this study was to examine whether an Integrated Approach to Health, Wellbeing and Productivity at Work (ITASPA) intervention would promote the mental health and wellbeing of workers. Methods Two worksites were recruited and offered the intervention and 76 cleaners agreed to participate in the scientific evaluation. At each worksite, employees developed initiatives to improve the psychosocial work environment, building on top of existing work environment programs, practices and procedures. The developed initiatives did not hold any physical activity components. The intervention was planned to run for 12 months, and this analysis presents data from the first of four follow-ups. Data on mental health and wellbeing were obtained using the SF12 and Orebro questionnaires. Using a stepped wedge design, participants functioned as their own controls. Data were analysed using a linear mixed model with random slope and intercept. Intercorrelation of repeated measurements was included in the models as random effect. Results The results showed significant decrease in sleeping problems (-4.04, 95% CI, -5,32- -2.75) after the intervention. Moreover, there was a non-significant increase in the amount of time participants had felt relaxed and calm (0.33, 95% CI, -0.10-0.96) and a small non-significant decrease in the amount of time participants had felt sad (-0.004, 95% CI, -0.42-0.41). Finally, results showed a small non-significant increase in how much physical pain had challenged the daily work (0.04, 95% CI, -0.21-0.30). Conclusion The findings show that ITASPA intervention led to significantly reduced sleep problems. There was a tendency of improved self-ratings of feeling relaxed and calm as well as reduced feeling sadness. The intervention did not decrease ratings of whether physical pain challenged the daily work, however, the worksites decided to focus on the psychosocial work environment and thus changes in mental health are expected to show greatest effects.


Background
Despite an intensive focus on worker health over the last three decades, the prevalence of work-related diseases remain largely unchanged in Denmark and internationally. In recent years, American and Australian researchers have developed new approaches to integrate health promotion, prevention of workrelated disease and organization of work. The aim of this study was to examine whether an Integrated Approach to Health, Wellbeing and Productivity at Work (ITASPA) intervention would promote the mental health and wellbeing of workers.

Background
The built environment is one of the main places where residents engage in their physical activity. Therefore, it is important to identify the track most frequently used by the population. This was done by designing a mobile application that charts the track that residents take when practicing their sports and sends them to a specially designed data hall to arrange and classify information. Since there are no tracks dedicated to exercising in the Jijel city, Algeria; the study aimed to identify the most frequently used tracks, as well as identify the points that constitute an obstacle in those tracks.

Methods
During April-May 2021, 107 people (76 men, 31 women) from city of Jijel (Algeria) participated in the study (Purposive Sample). Participants were provided with a mobile application (APK file) linked to a database that collects and arranges data and mapped with ArcGIS software. The experiment lasted for 30 consecutive days. Where the application was programmed to start automatically at 06:00 am to 09.00 am. The application maps participants' track, and identifying places where deceleration occurs.

Results
Around eighty-two percent (82.2%) chose three main tracks, two coastal tracks (A,B), and a mountain track (C), These are the paths that have been analysed and studied. A total of 2552 hours of data were collected, with an average of 29 hours per person. In the three tracks, there were 18 sub-tracks (less than 10 meters), These sub-paths are distributed as (A:06, B:09, C:03). The coastal tracks (A,B) witnessed a noticeable slowdown in movement speed. This slowdown is related to the presence of obstacles such as unpaved roads, congested traffic points and narrow pedestrian paths, which witness congestion in the morning. The mountain track (C) considered the least slowed path due to the absence of traffic congestion.

Conclusions
The tracks and the three lanes must be rehabilitated in a way that allows residents to engage in physical activity in a smooth and safe manner. Some changes have been suggested in the lanes and tion to Abstract citation ID: ckac095.122 P08-09 The promotion of walking through nudging. Evaluation of the app "Time2Walk''

Background
Walking is an appropriate mode to increase or maintain the physical activity behavior. However, physically inactive adults often need support in order to increase their physical activity level. The aim of the presentation is to inform about the nudging framework within the app Time2Walk, the recruitment of the study participants for both time points, and the development of the walking behavior over time.

Methods
The study participants were recruited via social media, press releases, advertising material and personal contacts. A pre-post single group study design was applied using an online questionnaire before and after the intervention. The intervention refers to a not so distant dystopian future where the city Graz (Austria) suffers from pollution, traffic chaos as well as climate change. Via regular walking as well as visiting places such as parks or other points of interest the users of the app were rewarded with tokens and could contribute to reversing the pollution. Four different types of behavioral nudges were applied during the use of Time2Walk in order to motivate people to walk more: awareness-raising (information about health and traffic related effects), social (information about guided walking tours), rewarding (tokenbased rewards), and stabilizing (daily walking targets) nudges.The app was developed as a central hub for conveying the nudges and for raising the players' awareness.
