The Obemat2.0 Study: A Clinical Trial of a Motivational Intervention for Childhood Obesity Treatment

Abstract

The primary aim of the Obemat2.0 trial was to evaluate the efficacy of a multicomponent motivational program for the treatment of childhood obesity, coordinated between primary care and hospital specialized services, compared to the usual intervention performed in primary care. This was a cluster randomized clinical trial conducted in Spain, with two intervention arms: motivational intervention group vs. usual care group (as control), including 167 participants in each. The motivational intervention consisted of motivational interviewing, educational materials, use of an eHealth physical activity monitor and three group-based sessions. The primary outcome was body mass index (BMI) z score increments before and after the 12 (+3) months of intervention. Secondary outcomes (pre-post intervention) were: adherence to treatment, waist circumference (cm), fat mass index (z score), fat free mass index (z score), total body water (kg), bone mineral density (z score), blood lipids profile, glucose metabolism, and psychosocial problems. Other assessments (pre and post-intervention) were: sociodemographic information, physical activity, sedentary activity, neuropsychological testing, perception of body image, quality of the diet, food frequency consumption and foods available at home. The results of this clinical trial could open a window of opportunity to support professionals at the primary care to treat childhood obesity. The clinicaltrials.gov identifier was NCT02889406.

Gut microbiota is associated with metabolic health in children with obesity

“…This was a cross-sectional observational study, secondary to a randomized clustered clinical trial on a motivational intervention to treat children with obesity. To perform the present study, we used the baseline anthropometry and biochemistry data along with the microbiota composition of the participants enrolled in the OBEMAT2.0 clinical trial [35].…”

Family‐reported barriers and predictors of short‐term attendance in a multidisciplinary intervention for managing childhood obesity: A psycho‐family‐system based randomised controlled trial (ENTREN‐F)

“…In line with these results, we highly recommend providing specific training on motivational techniques to paediatricians and nurses, who are well‐positioned in the primary care setting to detect childhood obesity and initiate interventions. In this regard, MI has shown promising results as a key facilitator in promoting the involvement of the participants, raising their levels of awareness and motivation to change, rather than simply providing guidelines on health behaviours (Borrello et al., 2015; Luque et al., 2019; Martínez Rubio & Gil Barcenilla, 2013; Skelton et al., 2011).…”

Validation of bioelectrical impedance analysis for body composition assessment in children with obesity aged 8-14y

“…This was a cross-sectional validation study, secondary to a randomized clustered clinical trial on a motivational intervention to treat children with obesity. To perform the present validation study, we used the baseline body composition data of the participants enrolled in the OBEMAT2.0 clinical trial [24].…”
