Brief Summary

The main goal of the study, Sustainable Office Intervention (SOFIA), is to promote and ease the adoption of a sustainable lifestyle within an office environment, with the dual goals of enhancing public health and mitigating the adverse effects of climate change. Specifically, the study aims to assess the effectiveness of promoting sustainable lifestyle choices in the office workplace compared to promoting a conventional healthy lifestyle in regards to diet and physical activity.

Outcome Measures

Primary Outcomes (4)

• Change in dietary patterns and intake of fruit and vegetable

  Assessment of dietary patterns by the food-frequency questionnaire Meal-Q, expressed as servings per day or grams per day of meat, dairy products, fruit and vegetable.

  Baseline, after 4 weeks and after 8 weeks.

• Change from baseline in dietary carbon dioxide equivalents

  Assessment of dietary Carbon dioxide equivalents (CO₂e) by converting data from Meal-Q to a daily intake of 50 nutrients by linkage to the National Food Composition Table as well as to a database with Life cycle assessment (LCA) data for 65 different food products to calculate greenhouse gas emissions CO₂e per day.

  Baseline, after 4 weeks and after 8 weeks.

• Change in physical activity level

  Assessment of physical activity by the self-administrated Web-based questionnaire Active-Q, expressed as metabolic equivalent of task value (MET).

  Baseline, after 4 weeks and after 8 weeks.

• Changes in concentration of urinary pesticide residues in urine

  Assessment of sustainable and organic food intake by measuring concentration of pesticide residues. Samples will be collected at two occasions; baseline (reference sample), and at the end (after 8 weeks) in 50ml FALCON polypropylene containers and stored at -80˚C until further analysis according to gold standard methods. The results will be calculated as μg pesticide/g creatinine to adjust for differences in urinary concentration.

  Baseline, and after 8 weeks.

Secondary Outcomes (26)

• Changes in dietary sustainability score

  Baseline, after 4 weeks and after 8 weeks

• Changes in the anthropometrical assessments (Body Mass Index)

  Baseline, and after 8 weeks.

• Stanford healthy Neighborhood Discovery Tool

  Week 6, workshop number 5 of 6.

• Experiences related to a healthy and sustainable lifestyle intervention

  Week 8, workshop number 6 of 6.

• Changes in intake of energy

  Baseline, after 4 weeks and after 8 weeks.

Study Arms (2)

Healthy lifestyle group (HL)

ACTIVE COMPARATOR

The control group will receive advice about a conventional healthy diet according to the Nordic Nutrition Recommendations (NNR 2014) and international physical activity recommendations from WHO. The participants will get information about the recommended distribution of energy from macronutrients i.e. energy coming from fat, protein, and carbohydrates, as well as general recommendations about the "plate model", i.e. the combination of food on the plate to adhere to the recommended nutrient intake. Additionally, they will receive instructions to increase physical activity to reach 150 to 300 minutes of moderate aerobic activity per week or the equivalent vigorous activity.

Behavioral: Healthy lifestyle

Sustainable lifestyle group (SL)

EXPERIMENTAL

The sustainable lifestyle group will receive instructions to increase the consumption of healthy organic plant-based foods that is carbon or environmentally friendly (i.e. fruits, vegetables, legumes, multigrain cereals, or labeled foods) and decrease consumption of beef and dairy products. We expect that the reduction of diet-related CO2e will be 50% as compared to the baseline, while the intake of nutrients such as fiber, vitamin C, and folate will increase. Additionally, they will receive instructions to increase active and emission-free transportation, i.e. walking and biking to and from work and meetings.

Behavioral: Sustainable lifestyle

Interventions

Sustainable lifestyle BEHAVIORAL

To encourage and nudge a sustainable lifestyle in an office context in order to improve public health and combat climate change.

Sustainable lifestyle group (SL)

Healthy lifestyle BEHAVIORAL

To encourage and nudge a healthy lifestyle in an office context, the participants in this arm will function as a control group receiving general recommendations based on NNR 2014 nutritional recommendations and WHO physical activity recommendations.
