The KING'S WHOLE Feasibility Study

Study Overview
=================
Brief Summary
-----------------
Office working life has changed dramatically over the last 50 years with digitalization; this is estimated to have decreased the amount of energy (calories) used during work. Employees who work long or irregular working hours or experience job strain are more likely to make less healthy food choices. The combination of these factors may contribute to increased body weight during a persons working life. The aim is to investigate the feasibility of an online lifestyle behaviour change intervention in office workers.

Detailed Description

Office working life has changed dramatically over the last 50 years with digitalization; this is estimated to have decreased the amount of energy (calories) used during work. Employees who work long or irregular working hours or experience job strain are more likely to make less healthy food choices. The combination of these factors may contribute to increased body weight during a persons working life. The aim is to investigate the feasibility of an online lifestyle behaviour change intervention in office workers. This feasibility randomized control trial is a remote study and will be conducted online. Participants will be randomized to one of two health and well being interventions. The study will last 14 weeks. Participants need to attend two on-line study appointments (at the start of week 1 and end of week 14) lasting approximately 30-45 minutes. In weeks 2, 6 and 10 participants will be asked to participate in a personalised one-to-one behaviour change on-line advice session with a research nutritionist/dietitian. Each session will last approximately 45 minutes. In weeks 1, 5, 9 and 14 participants will be asked to wear a wrist-worn activity monitor and report what you eat and drink for 3 days.

| Engagement | Percentage of eligible volunteers consented | 14 weeks | 
| Attrition | Percentage drop out | 14 weeks | 
| Intervention adherence | Participants complying with intervention. | 14 weeks | 
| Intervention adherence - sleep | Sleep hygiene adherence; Scores will range from 0 - 52, with higher scores representing poorer sleep hygiene | 14 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in body weight | Difference from baseline to post intervention in body weight (kg) | 14 weeks | 
| Change in energy and macro nutrient intake | Difference in energy intake (Kcal), and sources of energy (carbohydrates, fats, and protein) | 14 weeks | 
| Change in sleep duration | Difference in between baseline and post intervention (hours/night) | 14 weeks | 
| Change in physical activity intensity and duration | Difference in activity from MotionWatch (duration hours in vigorous and moderate activity) | 14 weeks | 
| Change in sleep quality score | Difference in score from PROMIS (Patient-Reported Outcomes Measurement Information System) questionnaire. Scores between 8 and 40, which are converted to T-Scores (min 28.9 - 76.5). Higher score = more disturbance | 14 Weeks |
