“…Other teams 29,30 also reported steeper weight losses with a combined approach than with a low-calorie diet alone and a positive correlation to the duration of the treatment. Altogether, a low-calorie diet appears unnecessary in children and adolescents to induce a negative energy balance when a multidisciplinary approach is used.…”

Effects of a multidisciplinary weight loss intervention on body composition in obese adolescents

et al. 2004

OBJECTIVE:To investigate if a multidisciplinary weight loss program in adolescents suffering severe obesity allows adequate growth and development and avoid lean mass loss. DESIGN: A total of 55 adolescents (33 girls and 22 boys) suffering severe obesity were enrolled in an interdisciplinary weight reduction program lasting 6-12 months. Progressive submaximal physical activity was performed and national dietary allowances for adolescents with low levels of physical activity energy were provided. MEASUREMENTS: Total and segmental body composition was assessed by means of dual-energy X-ray absorptiometry. RESULTS: The mean height significantly increased (Po0.001). The mean body mass index (BMI) dropped in boys from 34.573.2 to 25.572.3 kg/m 2 and in girls from 38.474.1 to 28.474.1 kg/m 2 . Height increased according to the expected pattern (Po0.001). Total lean mass (LM) did not vary and was positively correlated to pubertal development in both sexes before and after weight loss. Steepest drop in fat mass (FM) was observed in the trunk (À63.2710.1% in boys and -51.5711.4% in girls). Decrease in BMI and FM was tightly correlated in both sexes. However, slopes significantly differed (Po0.0005) so that a decrease of 1 kg/m 2 in BMI corresponded to a decrease of 3.92 kg in FM in girls and of 5.44 kg in boys. In each sex, FM at baseline and duration of the treatment were the main determinants of the decrease in FM. CONCLUSION: During adolescence, despite a major weight loss, adequate growth and preservation of LM can be achieved. Weight loss kinetics markedly differs between boys and girls. Low-calorie diets are unnecessary to achieve a marked reduction of severe obesity during puberty. International Journal of Obesity (2004) 28, 290-299. doi:10.1038/sj.ijo.0802542Keywords: adolescents; diet; exercise; body composition IntroductionThe steep increase of obesity in children and adolescents is partly due to major changes in lifestyle in all industrialized countries. In France, the prevalence of obesity has doubled every 15 y since 1970 and reached 16% in 2000. 1 It has been extensively demonstrated that low physical activity levels are a cause and a consequence of overweight. 2 Obese children tend to remain obese in adulthood. 3 Many severe complications of adult obesity are embedded in childhood and adolescence. 4 So strategies are needed to prevent and to treat childhood obesity. 2,5 The treatment of obese children and adolescent should aim at decreasing fat mass (FM), avoiding loss of lean body mass, ensuring adequate growth and development and preventing cyclic weight regain. 2,6 Improving well-being is a second major aspect since psychological disturbances and social distress tend to be early features of obesity in the young. As such a multidisciplinary approach proves to be difficult to reach in the usual environment, in-patient units have been designed to help adolescents suffering the most severe forms of obesity. 7,8 Managing weight loss in obese adolescents actually requires paying special attention to potential...

“…The sample consisted of 10 boys and 20 girls with a mean age of 13.1 y AE 2.0 (range 9 -17). At pretreatment, mean percentage of overweight was 180% AE 24.3, mean body mass index was 33.5 AE 4.9, mean adjusted body mass index 23 was 181 AE 26.4.…”

Effects of distraction on treadmill running time in severely obese children and adolescents

et al. 2002

OBJECTIVE: (1) To examine the effects of attentional distraction on running time in an incremental treadmill test in obese youngsters; (2) to investigate whether distraction works at the same extent at the beginning and at the end of residential treatment; and (3) to explore the underlying mechanisms of the possible distraction effects. METHODS: Thirty severely obese youngsters (10 boys, 20 girls, age range 9 -17) who were following a 10 month residential treatment, performed a treadmill test until exhaustion in four different sessions using a within subjects design. The two sessions at the beginning of the treatment and the two sessions at the end the treatment were counterbalanced, one with attentional distraction (music) and one without distraction. RESULTS: Obese youngsters ran significantly longer during distraction. This distraction effect seemed to be larger at the beginning compared to at the end of obesity treatment. The absence of differences between the condition with music and the condition without music on perceived bodily symptoms is in line with the idea that it took longer to perceive sufficient bodily sensations to decide to stop the treadmill test in the distraction condition. This interpretation is further corroborated by the physiological data indicating a superior peak performance in the condition with distraction. CONCLUSIONS: Attentional distraction has a positive effect on perseverance in obese youngsters. Further research has to show the usefulness of attentional distraction as a technique to increase exercise adoption and adherence in obesity treatment.

We investigated whether youngsters with obesity (n ¼ 39) differed from a control group (n ¼ 39) in their self-reported attitudes towards and in their implicit identification with physical activity and food. Self-reported attitudes were assessed using a rating scale; implicit identification was assessed using a self-concept Implicit Association Task (IAT). Results revealed a marked group difference on the implicit identification with food: Only youngsters without obesity identified themselves more with non-fat food than with fat food. r
