Adolescence is a complex period of human development in which young people are susceptible to unhealthy behaviors, such as physical inactivity and an unbalanced diet. This study aimed to analyze the effects of 12 weeks of multi-disciplinary family and individual intervention on cardiometabolic risk parameters in overweight and obese adolescents and compare sub-groups, considering possible differences between sexes (males vs. females vs. intervention approach). Forty-three adolescents (13.73 ± 2.46 years old) of both sexes were divided into two groups: family group (FG) (n = 21; 14.24 ± 2.61 years old) and individual group (IG) (n = 22; 13.23 ± 2.27 years old). The following parameters were evaluated: anthropometry (body weight, height, waist circumference (WC), hip circumference (HC), abdominal circumference (AC), calculation of body mass index (BMI), and waist–hip ratio (WHR)), body composition (fat mass (FM), lean mass (LM), fat-free mass (FFM), skeletal muscle mass (SMM), body fat percentage (BF), and visceral fat), biochemical measures (fasting glucose, triglycerides (TG), total cholesterol (TC), low-density lipoproteins (LDL-c), and high-density lipoproteins (HDL-c)), and the measurement of systolic and diastolic blood pressure (SBP and DBP) before and after the interventions. The multi-disciplinary interventions occurred for 12 weeks (three days a week lasting 1 h and 30 min, in which 30 min were dedicated to theoretical interventions (nutrition: nutritional education and psychology: psychoeducation) and 1 h to physical exercises. A time effect was observed for LM, FFM, SMM, FM, and HDL-c, with higher values after intervention and a significant decrease for FM, BF, visceral fat, fasting glucose, TG, TC, LDL-c, and DBP (p < 0.05). However, no group, sub-group, or interaction effects were observed when comparing FG, IG, or sexes (p > 0.05). The responses of the present study show that both multi-disciplinary approaches (family and individual) promoted improvement in the body composition indicators, biochemical markers, and DBP of overweight and obese adolescents independently of the intervention group. Given this finding, health professionals, families, and adolescents could choose the type of intervention based on their preferences.

The food consumption of adolescents has changed nowadays, with an increase in ultra-processed food that in general shows higher calories and lower nutrients. Because of this, the objective of this study was to investigate the impacts of a 12-week multi-professional family versus isolated intervention on the food level processing of overweight adolescents. A randomized clinical trial study was carried out in which adolescents (n = 43; mean aged 13.73 years) who were divided into FG—family group (n = 21; the adolescents performed the activities with their parents) and IG—isolated group (n = 22; the adolescents performed the activities alone). The parameters measured before and after 12 weeks of multi-professional intervention (physical exercise, nutrition and psychoeducation) were: body mass, height and body mass index-BMI. The level of food processing was analyzed using a three-day food recall (24hR), classified according to the Food Guide for the Brazilian Population (fresh, minimally, processed and ultra-processed foods). The main results show that there was only a significant reduction in the consumption of processed foods (FG: 7.93%; IG: 49.73%) and ultra-processed foods (FG: 35.06%; IG: 67.16%) in grams (FG: 22.29%; IG: 65.23%) and calories (p < 0.05; for all comparisons). The consumption of fresh foods in grams (FG:61.97%; IG: 147.13%) and calories (FG: 147.13%; IG: 118.03%) and minimally processed foods (FG: 27.45%; IG: 14.64%) in grams increased significantly (p < 0.05; for all comparisons). However, no significant differences were observed between all variables analyzed for the groups, nor any interaction (p > 0.05). In conclusion, both groups who participated in the activities showed positive changes with increased consumption of fresh foods and reduced consumption of processed foods, without difference between them.

Introduction: there is evidence that multidisciplinary interventions are an efficient approach to achieving weight loss and other health-related goals. However, dropout rates of these programs are high among adolescents. The suggestion is that understanding the motivation of individuals to participate in these projects is fundamental to developing strategies for permanence and, consequently, promoting better results. Objective: the main aim of this study was to describe the motivations of overweight adolescents participating in a multidisciplinary health promotion project. Methods: this qualitative study was conducted from March to July 2021 using the Bardin content analysis technique. The tool used for data collection was the semi-structured interview, analyzed means by the software QSR NVivo 11 by grouping the speech into clusters. These, in turn, were evaluated in three categories: (1) motivation, (2) food, and (3) physical exercise. Results: the age of the participants was 13.8 ± 2.4 years old, with body mass index of 31.8 ± 8.5 kg/m². Regarding family income, 41.66% had a monthly payment of 3 to 6 minimum wages. Regarding parents’ educational level, 70.83% of mothers had completed higher education, while 29.16% had completed high school. According to the respondent’s answers, weight loss was the greatest motivation to participate in a multidisciplinary obesity treatment program. In category 2, it was observed that adolescents associated the act of eating with feelings such as anxiety and nervousness. In category 3, the impact of the pandemic was found under the modalities of physical exercise practiced. Conclusion: the results describe the motivation of overweight adolescents to participate in a multidisciplinary program, in addition to elucidating participants’ perception of their health and related habits, strategies for health promotion, and consequent improvement of the quality of life of these individuals.
