Objective The present study was to determine the effect of a combined exercise and dietary program on cognitive function as well as the relationship between the program-induced weight change and cognitive function alterations. Design The study applies a quasi-experimental design. Methods Fifty-eight adolescents with obese status (body mass index, BMI >28 kg/m2) were assigned to either an experiment (n = 30) or control group (n = 28). Participants in the experiment group received a scheduled program with a specific exercise protocol (two sessions per day, six days per week) and diet plan for four consecutive weeks; the control group was instructed to maintain their normal school activities. The primary outcome measures were anthropometric data and flanker task performance. Results The combined program led to reduced BMI with maintenance of the incongruent accuracy in the experiment group, but the incongruent accuracy decreased in the control group after the four-week period. Additionally, the change in weight status between post- and pre-test measurements was inversely correlated with the change in incongruent accuracy. Conclusion The combined exercise and dietary program resulted in decreased weight and enhanced executive function in the obese adolescents, and the weight alteration may be considered the mediator between the intervention and executive function.

Acute Response

Introduction: Cardiovascular complications are a leading cause of mortality in nonalcoholic fatty liver disease (NAFLD). Fructose has been reported to be associated with dyslipidemia and increased cardiovascular risk in adults but its impact on adolescents with NAFLD is not well understood. We previously demonstrated that fructose disproportionately increased postprandial hypertriglyceridemia in pediatric NAFLD as compared to healthy children. However, the mechanism remains unclear. Hypothesis: We hypothesized that fructose would contribute to hypertriglyceridemia in pediatric NAFLD by increasing the size of VLDL particles. Methods: We examined the acute response to a single dose of fructose beverage in 50 Hispanic-American obese adolescents with varying degrees of hepatic steatosis. Those with hepatic fat >5% on MRI imaging were designated as presumed NAFLD. Subjects consumed a 12oz drink containing 33g of fructose and plasma samples were collected at baseline and 30, 60, and 90 minutes afterwards. Plasma lipoproteins were measured using NMR (Liposcience, Raleigh, NC). Results: In response to acute fructose load, subjects without NAFLD increased the total number of TG rich lipoprotein particles (p = 0.047). However, this increase was not observed in subjects with NAFLD; instead, they increased the subpopulation of large VLDL particles (p = 0.008) and the mean size of VLDL particles (p = 0.004) (Figure 1). In line with this finding, TG-to-apoB ratio significantly increased in subjects with NAFLD (2.25 ± 0.26 to 2.37 ± 0.25, p = 0.031) but not in non-NAFLD. Conclusions: These findings demonstrate that adolescents with NAFLD have more atherogenic, large VLDL in response to fructose compared to obese adolescents without NAFLD. Dietary fructose restriction may be a critical component in the treatment of NAFLD associated cardiovascular disease and should be tested further.

Abstract The relationship between parental support and physical activity enjoyment appears to be mediated by individual-level factors. The aim of this study was to examine whether the relationship between perceived parental support and physical activity enjoyment is mediated by overweight and obese adolescents’ physical fitness, both subjectively and objectively assessed. A total of 163 participants (mean age =14.30 years, 55.8% boys) with an average body mass index of 28.97 kg/m2 took part in this study. Participants completed a questionnaire of parental influence regarding physical activity, a questionnaire of physical self-perception and several fitness tests (cardiorespiratory fitness, lower limbs muscular strength and flexibility) using the ALPHA-fitness battery. The results showed that relationship between perceived parental support and physical activity enjoyment is mediated by the overweight and obese adolescents’ perceived cardiorespiratory fitness and flexibility. We suggest to create educational guidelines for parents to increase the support and improve overweight and obese students’ positive perceived physical competence, in order to achieve a greater adherence to physical activity and greater physical activity enjoyment.

The Relationship

Mediating role of coping styles in the relationship between anxiety and health behaviors of obese adolescents Obesity is one of the major health problems in adolescents. Health-detrimental lifestyle (i.e. lack of physical activity, inappropriate nutrition) as well as maladaptive styles of coping with stress are regarded as belonging among determinants of obesity. The aim of the study was to establish factors mediating between anxiety and diet-related health behaviors. Participants in the study were 113 adolescents with obesity whose body weight was over 97th centile. They were examined using a set of self-report questionnaires to measure anxiety, coping styles and health behaviors. Emotion-focused coping and seeking social contacts (social diversion) were found to act as mediators between adolescents' trait anxiety and their health behaviors. The findings suggest that to enhance obese adolescents' health-promoting behaviors appropriate conditions should be ensured that would not only enable them to express their emotions, but also promote their socializing with peers.

The aim of the present study is a comparison of family relations in families with an obese adolescent and families with a normal-weight adolescent. Particularly, we studied the parents' and children's perceptions of some crucial areas of their relationship, e.g., communication, support, and some factors of “psychosocial risk” for the adolescents. We compared 30 family triads each with an obese child and 30 family triads each with a normal-weight child. We used a questionnaire aimed to evaluate some crucial variables of family functioning such as communication, family climate, support and satisfaction. A multivariate analysis of variance yielded no difference between obese and nonobese adolescents concerning communication with their mothers and fathers and concerning support given and received from them. In particular, analysis indicated no difference between parents of obese adolescents and parents of normal-weight adolescents regarding openness and problems in communication. As a protective factor against psychosocial risk, in both the samples the relationship with the mother arises as relevant, but, for the nonobese adolescents, both support and communication with this parent were important, whereas for the obese adolescents only support seemed to be really important. The results are discussed with respect to this approach which considered the family as the unit of analysis both from a theoretical and a methodological point of view.

Background. Obesity is a multifactorial disease that is one of the important public health problems in the 21st century. Functional bowel disorders in obese children and adolescents are one of the most common pathologies of the digestive tract. The aim: to characterize the bacteriological composition of the colon microbiota in obese adolescents and identify its associations with the clinical manifestations of functional bowel disorders.Materials and methods. The study included 20 adolescents aged 11–17 years. Stool consistency was assessed using the Bristol Stool Scale. The study of biological material was carried out using standard bacteriological methods. To assess the strength of the relationship between the nominal variables, Cramer’s V test was used.Results. It has been shown that in adolescents with obesity and functional bowel disorders, there is a decrease in the number of representatives of bifidoflora, an increase in the microbial density of Escherichia coli with altered enzymatic properties and an excessive growth of potentially pathogenic enterobacteria. In obese adolescents with functional bowel disorders, abdominal pain associated with the act of defecation is associated with the presence of enterobacteria and E. coli with altered enzymatic properties. Rare bowel movements are associated with an increased abundance of Enterococcus spp. and the presence of opportunistic Enterobacteriaceae microorganisms. Frequent bowel movements are associated with the presence of E. coli with altered enzymatic properties and Clostridium spp. In the presence of loose stool, Clostridium spp. is present; unstable stool (alternation of hard and liquid stools in one patient) is associated with a decrease in the number of lactobacilli and E. coli with normal enzymatic properties, the appearance of E. coli with altered enzymatic properties, opportunistic microorganisms of Enterobacteriaceae family and Clostridium spp. Conclusion. The relationship between the clinical symptoms of functional bowel disorders and changes in the composition of the gut microbiota in obese adolescents may be a justification for conducting in-depth studies aimed at finding early predictors of functional bowel diseases associated with obesity in the adult cohort.
