Background: Prolonged sedentary time is associated with an increased incidence of chronic disease including type 2 diabetes mellitus (DM2). Given that occupational sedentary time contributes signifcantly to the total amount of daily sedentariness, incorporating programmes to reduce occupational sedentary time in patients with chronic disease would allow for physical, mental and productivity benefts. The aim of this study is to evaluate the short-, medium- and long-term efectiveness of a mHealth programme for sitting less and moving more at work on habitual and occupational sedentary behaviour and physical activity in ofce staf with DM2. Secondary aims. To evaluate the efectiveness on glycaemic control and lipid profle at 6- and 12-month follow-up; anthropometric profle, blood pres‑ sure, mental well-being and work-related post-intervention outcomes at 3, 6 and 12months. Methods: Multicentre randomized controlled trial. A sample size of 220 patients will be randomly allocated into a control (n=110) or intervention group (n=110), with post-intervention follow-ups at 6 and 12months. Health professionals from Spanish Primary Health Care units will randomly invite patients (18–65 years of age) diagnosed with DM2, who have sedentary ofce desk-based jobs. The control group will receive usual healthcare and information on the health benefts of sitting less and moving more. The intervention group will receive, through a smartphone app and website, strategies and real-time feedback for 13weeks to change occupational sedentary behaviour. Variables: (1) Subjective and objective habitual and occupational sedentary behaviour and physical activity (Workforce Sit‑ ting Questionnaire, Brief Physical Activity Assessment Tool, activPAL3TM); 2) Glucose, HbA1c; 3) Weight, height, waist circumference; 4) Total, HDL and LDL cholesterol, triglycerides; (5) Systolic, diastolic blood pressure; (6) Mental well being (Warwick-Edinburgh Mental Well-being); (7) Presenteeism (Work Limitations Questionnaire); (8) Impact of work on employees´ health, sickness absence (6th European Working Conditions Survey); (9) Job-related mental strain (Job Content Questionnaire). Diferences between groups pre- and post- intervention on the average value of the vari‑ ables will be analysed. Discussion: If the mHealth intervention is efective in reducing sedentary time and increasing physical activity in ofce employees with DM2, health professionals would have a low-cost tool for the control of patients with chronic disease.
