[Motivational intervention for obesity in Primary Care using a physical activity program].

Objective: to evaluate the effectiveness of the obesity intervention with three different approaches, one of them with a platform that promotes physical activity. Material and method: randomized, controlled, parallel clinical trial that compared 3 arms, multicenter study in overweight or obese patients with a follow-up of 12 months. The patients were randomized into three groups: Intervention in the primary care center with G1 intervention: Control group, which received the usual recommendations to lose weight following the SEEDO 2000 Consensus. G2: Motivational intervention of obesity (IMOAP) with trained nurse and small periodic work groups. G3: Motivational intervention of obesity (IMOAP) adding the use of a digital platform that allows physical activity to be recorded, monitored and at the same time favors the practice of this (iwopi). Variables were collected: weight, height, BMI, circumference of the waist, lipid parameters, blood pressure, glycosylated hemoglobin. Results: 185 patients were initially included in the study. Seventeen patients left the study. Thus, 168 patients completed the study: 47 in G1, 61 in G2 and 60 in G3. Of the population studied, 57.1% were women. observing a general average weight reduction at the end of the study of 4.37 kg, being 5.34 kg in the group 2.6.29 kg in the group 3 and 1.25 kg in the control group (G1). It was also observed that cholesterol levels in three groups were reduced. at did not reach a statistically significant value. The clinically relevant parameters were: group 1 (control) versus group 2 (IMOAP): relative risk (RR), 0.10 to 0.46; relative risk reduction (RRR), 0.54 to 0.90; absolute risk reduction (ARR), from 0.30 to 0.61; number needed to treat (NNT), 3 to 2. Group 1 versus group 3 (IMOAP-PA): RR, 0.07 to 0.30; RRR, 0.70 to 0.93; ARR, 0.61 to 0.86; NNT: 2 to 1. Group 2 versus group 3: RR, 0.54 to 0.84; RRR, 0.16 to 0.46; ARR, 0.14 to 0.43; NNT, 7 to 2. Conclusions: The digital health platform that stimulates physical activity added to an interventionist motivation in overweight or obese patients is a significant additional benefit in terms of weight loss results, reduction of BMI and lipid profile in patients affected by overweight or obesity and a more effective cost.
