Abstract

Objective: To analyze the effect on weight reduction in overweight and obese patients through three intervention methods. Material and methods: Prospective, randomized, multicentric intervention study in overweight and obese patients with a 12-month follow-up. Patients were randomized into three intervention groups: Obesity motivational intervention with previously trained nurse (G1), lower intensity consultation, no motivational group, digital platform support (G2), and a third group that received a recommendation to lose Weight and follow-up in primary care consultation (G3). Weight, height, BMI, abdominal waist circumference, Lipid Parameters, Blood Pressure and Blood Glucose were collected. Results: The study enrolled 176 patients, of whom 60 were randomized to Group 1, 61 to Group 2 and 55 to Group 3. 58% of the populations were women and 42% men, being therefore the global ratio between men and women from 1 to 2.65. In all three groups the weight decreased in each visit, with an overall mean reduction at the end of the study of 3.9 kg. It can be seen how the three groups reduce total cholesterol, although the G1 with motivational intervention reduces it significantly more with respect to G2 and G3. On the other hand Triglycerides are significantly reduced by the two study groups. And HDL-C is increased in all three groups. Conclusions: The three groups managed to reduce weight, although the group with motivational intervention and telemedicine showed significant differences.
