Effectiveness of a multifactorial intervention based on an application for smartphones, heart-healthy walks and a nutritional workshop in patients with type 2 diabetes mellitus in primary care (EMID): study protocol for a randomised controlled trial

Introduction

New information and communication technologies (ICTs) may promote lifestyle changes, but no adequate evidence is available on their combined effect of ICTs with multifactorial interventions aimed at improving diet and increasing physical activity in patients with type 2 diabetes mellitus (DM2). The primary objective of this study is to assess the effect of a multifactorial intervention to increase physical activity and adherence to Mediterranean diet in DM2.

Methods and analysis

Study scope and population: The study will be conducted at 'La Alamedilla' primary care research unit in Salamanca (Spain). 200 patients with DM2 of both sexes, aged 25–70 years and who meet the inclusion criteria and sign the informed consent will be recruited. Each participant will attend the clinic at baseline and 3 and 12 months after intervention.

Intervention

Both groups will be given short advice on diet and physical activity. The intervention group will also take five heart-healthy walks and attend a group session on diet education and will be trained on use of an application for smartphone (EVIDENT II) for 3 months.

Variables and measurement instruments

The main study endpoints will be changes in physical activity, as assessed by a pedometer and the International Physical Activity Questionnaire, and adherence to the Mediterranean diet, as evaluated by an adherence questionnaire and the Diet Quality Index. Anthropometric parameters and laboratory values, lifestyles and quality of life will also be assessed.

Ethics and dissemination

It was approved by the Clinical Research Ethics Committee of Salamanca on 28/11/2016.

Trial registration

NCT02991079; Pre-results.
