1. Health Behavior: What behavior do you aim to change?
- Aiming to change college students’ sedentary behavior which is typical of a lifestyle that involves long hours of studying, attending classes, using laptops, tablets, and smartphones etc. in a seated position
- Especially higher in more developed countries
- Sedentary behavior is any waking behavior characterized by an energy expenditure ≤1.5 metabolic equivalents (METs), while in a sitting, reclining or lying posture (https://www.ahajournals.org/doi/pdf/10.1161/CIRCRE…)
- Sedentary behavior is among the leading modifiable risk factors worldwide for cardiovascular disease and all-cause mortality, irrespective of their levels of physical activity when not sedentary (dose-response association).
- Prolonged total sitting time and sedentary behaviors have been associated with increased risk of obesity, cardiovascular disease, cancer, and diabetes
- Sedentary behavior has positive associations with waist circumference, body mass index, triglyceride levels
- Most people living a sedentary lifestyle are unlikely to be meeting the national physical activity guidelines. According to the HHS Physical Activity Guidelines, adults should be getting at least 150 minutes of moderate-intensity physical activity each week.
2. Target Population/Community: What community or population’s behavior are you aiming to change?
The behavior that we will be targeting is the sedentary lifestyle of college students living in the UCSD dorms. We chose this population because after the pandemic most of these students have to be confined to their rooms to maintain social isolation protocols and as a lot of the physical activity came from walking to and from class, having to do classes from their rooms makes their lives much more sedentary which can have significant ergonomic repercussions in the future. As the campus opens up we want to show students how too get out of their sedentary lifestyles.
3. Community level factors: What community level factors are you aiming to change?
The physical environment (built environment): which includes safe walkable paths, bike lanes, and the inclusion of a new gym that emphasizes access and diversity in activities. An increased funding and inclusion of methods to increase standing, ie. standing desks
Goal: get more students on campus to do some form of exercise by providing a multitude of options and motivation to decrease sedentary behavior
Increase students willingness to want to exercise on campus by promoting safety measures such as more lights and emergency call stations to encourage those that were weary prior to want to join
4. Second level of Social Ecological Model targeted: Choose one other level of the SEM that your intervention will target. What intervention strategies might you use at that level to change your chosen behavior?
CHOOSING BETWEEN INDIVIDUAL AND POLICY:
Individual
– Change attitudes about exercise through free aerobic, muscle strengthening classes at RIMAC and increase knowledge / autonomy
– Increase motivation through a fitness tracker app: if everybody walks x steps, UCSD will donate to a charity OR walk x steps a day to exchange for dining dollars
Policy
– increasing the amount of time in between classes (currently: 10mins) so that students are more willing to walk around campus and openly plan class schedules that are further from each other
5. Previous Intervention research: Include a pdf of a scientific publication for one intervention study that changed the behavior your intervention will target. The previous study does not need to be in the same community or target population as your intervention. In your outline, list the title of the publication and what community/target population was used.

Title: Targeting Reductions in Sitting Time to Increase Physical Activity and Improve Health
Target population: Overall Western population
INterventions:
- -behavior is determined by individual, social, environmental and policy levels
- -environmental changes to the workplace
- Printer being on a different floor than printing
- Smartphone notifications when inactivity is detected
- Provision of physical structure
- Parks
- Sidewalks
- Neighborhood destinations
- Environmental changes in neighborhoods
- Walking paths
- Biking paths
6. Your intervention’s use of previous research: What strategies did the previous intervention research (included as #5) use that you might use in your intervention?
7. Theory(s) or model(s) guiding the intervention: Identify specific constructs from the theory you plan on using to guide your intervention development.
Social Cognitive Theory:
– self-efficacy: confidence in the ability decrease sedentary lifestyle and slowly building a healthy habit
– behavioral capability: knowledge on ways to decrease sedentary lifestyle such as stretching, walking, or just standing, as well as the merits of these activities
– vicarious learning: modelling the non-sedentary behavior from others. E.g. observing others who use standing desks would motivate some students to use them more. Seeing others walk and stretch more during, after, and in-between classes may motivate students to do the same and minimize students’ hesitance in engaging in novel behaviors
– reinforcement: promote incentives in response to healthful and non-sedentary behaviors, affecting recurrence and building habits
– situation: built environment will allow them to perceive the environment as promoting physical activity and decreasing sedentary behaviors.
