Brief summary
This study is a randomized clinical trial with two interventions: control group and intervention interdisciplinary group, without cross-over. Control Group (CG): In this type of intervention, the focus will be the development of skills through educational activities on health using the pedagogy of transmission. Interdisciplinary Intervention Group (IG): In this type of intervention, the focus will be the development of skills through educational activities on health that provide the development of autonomy and empowerment for behavior change, based on interdisciplinary motivational strategies. All topics will be focused on the major cardiovascular risk factors considered modifiable. The staff is trained to the techniques of motivational interviewing and transtheoretical model of change and the health issues related to the modification of lifestyle. So this interdisciplinary intervention with adolescents seeks to measure the result of an educational proposal using the techniques of motivational interviewing and transtheoretical model of change, for all professionals involved independent training in health issues related approach to lifestyle modification and the inclusion of family in this process.
Detailed description
This study is a randomized clinical trial with two interventions: control group and intervention interdisciplinary group, without cross-over. Interventions will take place at the Rehabilitation Hospital São Lucas Center (CR), will have 12 sessions for each of the following ways: Control Group (CG): In this type of intervention, the focus will be the development of skills through educational activities on health using the pedagogy of transmission. The meetings will be weekly with 45 minutes duration on a schedule of lectures about cardiovascular risk factors and prevention.The sample is 60 adolescents with overweight or obesity. Interdisciplinary Intervention Group (IG): In this type of intervention, the focus will be the development of skills through educational activities on health that provide the development of autonomy and empowerment for behavior change, based on interdisciplinary motivational strategies. Therefore, group meetings will be performed in the presence of a member of the nursing staff, physiotherapy, nutrition and psychology. The meetings are weekly, lasting 1 hour and 45 minutes. In the first 1 hour and 15 minutes will be addressed health issues related to lifestyle modification (self-care, healthy eating and physical activity) using the fundamentals of motivational interviewing technique. All topics will be focused on the major cardiovascular risk factors considered modifiable. The staff is trained to the techniques of motivational interviewing and transtheoretical model of change and the health issues related to the modification of lifestyle. During the sessions the team members address the health issue so that the knowledge of a professional complements the other. At the same time occur the integration of knowledge between these professionals from different areas aiming to encourage teens to lifestyle modification based on the techniques of motivational interviewing and transtheoretical model of change. Likewise, it is envisaged to include a time of physical activity (30 minutes) oriented in conjunction with the research team. This activity aims to motivate adolescents to include other physical activity sessions during the week. So this interdisciplinary intervention with adolescents seeks to measure the result of an educational proposal using the techniques of motivational interviewing and transtheoretical model of change, for all professionals involved independent training in health issues related approach to lifestyle modification and the inclusion of family in this process. Run in: There will be a meeting with the parents of the IG and CG (separately) in order to inform them about the participation of children in the program and guide them about the procedures of the research protocol.
