About this study
Official title: ´Sit Less, Move More' at Work: Impact of a mHealth Intervention on the Glycaemic Control and Anthropometric Profile of Office Employees With Diabetes Type 2. A Randomized Controlled Trial.
The objective of the study is measuring the impact of a ´sit less, move more' mHealth intervention at work on the glycaemic control and anthropometric profile of office employees with diabetes type 2 (DT2) at short, mid and long term.
Read the detailed description
A double-blind randomized controlled trial. Seven Primary Care Centers from Spain (n=5 Catalonia, n=2 Madrid), 2 hospitals (n=1 Catalonia, n=1 Madrid) and 2 companies (occupational health services; n=1 public, n=1 private) will participate in the study. In each center, physicians, nurses, endocrinologists and occupational physicians will recruit patients with DT2 who spend at least 55% of their working hours doing desk-based tasks (OSPAQ) and have a cellphone. Following the CONSORT Statement (2010), volunteers will be randomized into a control (CG) or intervention group (IG) by the research team using a computer program to generate the random sequence. 184 individuals are needed in each group. Main variables: fasting glucose levels, HbA1c, weight, height, BMI, waist circumference. Occupational sitting time and sitting time breaks will be measured using ActivPAL devices. Other variables: physical activity (IPAQ short), quality of life (EuroQool), presenteeism (WLQ), triglycerides, total cholesterol (LDL and HDL), blood pressure and sociodemographic variables.
Intervention: A mHealth program (13 wks) will progressively replace occupational sitting time with light physical activities. Participants from the CG will receive usual care. Multivariate analysis will assess changes over time (post intervention and at 6 months follow up) in the dependent variables; looking at differences between groups. Intention to treat will be applied.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Walk@WorkApp-DiabBehavioural
Also called mHealth intervention
The intervention (Walk@WorkApp-Diab), based on an mHealth program, consists on replacing sedentary job tasks for active ones, during 13 weeks. The intervention group will download the mHealth program into their personal cellphones
| Study group | Role | What they receive |
|---|---|---|
| Intervention Group | Experimental | In the intervention group, subjects will receive brief advice on occupational physical activity, sedentary behaviour and Diabetes Type 2. In addition, participants will be provided with an external movement sensor that will be linked to the Walk@WalkApp-Diab for Android and iOS. This App will monitor the time participants spend sitting, walking and standing during working hours. It will also provide participants with strategies to "sit less and move more" at work throughout 13 weeks. This mHealth intervention aims to change occupational sitting by replacing desk-based activities by active tasks. Receives: Behavioral: Walk@WorkApp-Diab |
| Control Group | No intervention | Subjects will receive brief advice on occupational physical activity, sedentary behaviour and Diabetes Type 2. |

Questions about this trial
What is this clinical trial studying?
A study testing Walk@WorkApp-Diab in people with Diabetes Mellitus, Type II, run by Fundacio d'Investigacio en Atencio Primaria Jordi Gol i Gurina at 1 site in Spain.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 17 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Anna Puig-Ribera (+34 619352497, annam.puig@uvic.cat), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Fasting glucose levels (time frame: Two measurement points: (a) Before the intervention starts, (b) at 6 months after intervention has finished). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04092738, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
