Summary

This study aims to analyze the effects of a 3-month self-applied online program, focused on promoting healthy lifestyle habits (healthy eating and increased physical activity), on adults with obesity. Participants will be recruited by 8 doctors from 6 public Health Centers. These patients will be randomized allocated into two interventional groups: the experimental group will receive audiovisual instructions from their specialist doctor, and the control group from a doctor outside the patient. Assessment will include sociodemographic variables, body mass index, blood pressure, glycemic and lipid metabolism variables, physical activity level, adherence to the Mediterranean diet, therapeutic alliance, and health-related quality of life. The randomization process will be stratified according to BMI, therapeutic alliance, age, and sex.

Detailed description

Obesity or being overweight, even other associated comorbidities, involve a worrying public health problem. The evidence shows that healthy eating and regular physical exercise, monitored by different means (internet, face to face, exercise diaries), play an important prevention role to maintain health while ageing. In this way, Information and Communication Technologies (ICTs) have been demonstrated as a useful tool to promote health, working on barriers at the same time, such as low motivation and difficulties maintaining regular exercise and/or healthy eating habits. ICTs also allows to reach a wider audience at a lower cost, due to their good cost-benefit relationship and the possibility of increasing the efficiency of interventions. Therefore, this study aims to analyze the effects of a 3-month self-applied online program, focused on promoting healthy lifestyle habits (healthy eating and increased physical activity), on adults with obesity. Participants will be recruited by 8 doctors from 6 public Health Centers. These patients will be randomized allocated into two interventional groups: the experimental group will receive audiovisual instructions from their specialist doctor, and the control group from a doctor outside the patient. Assessment will include sociodemographic variables, body mass index, blood pressure, glycemic and lipid metabolism variables, physical activity level, adherence to the Mediterranean diet, therapeutic alliance, and health-related quality of life. The randomization process will be stratified according to BMI, therapeutic alliance, age, and sex.
