Obezita se v posledních letech dostává do centra zájmu lékařů a psychologů. Důvodem není jen její masový výskyt, ale i primární vliv na další onemocnění - kardiovaskulární a onkologická. Kurzy redukce nadváhy jsou jednou z aktivit v primární prevenci těchto onemocnění. Behaviorálni terapie nadváhy v Centru zdravého způsobu života spočívá v posilování motivace respondentů snížit hmotnost, udržet si váhový úbytek a jeví se jako nejlepší metoda práce s obézními klienty.
In recent years attention of medical doctors and nsvchologists is focused on obesity. The reason is not its mass incidence but its primary effect on other diseases - cardiovascular and oncological ones. Weight reduction classes are one of the - cardiovascular and oncological ones. Weight reduction classes are one of the weight in the Healthy Lifestyle Centre involves stimulating the respondents motivation to reduce thebr weight, to maintain the weight loss. It seems to be the best working method with obese sibjects.

Among the factors influencing weight loss and maintenance, psychobehavioral, nutritional, metabolic, hormonal and hereditary predictors play an important role. Psychobehavioral factors influence adherence to lifestyle changes and thus weight loss maintenance. The outcome of short-term weight reduction treatment is mainly affected by changes in energy and nutrient intake and physical activity and thus the impact of hormones can possibly be obscured. In order to reveal hormonal determinants of weight loss, a 4-week in-patient comprehensive weight reduction program was introduced in which food intake and physical activity were under the strict control. Women (n = 67, BMI: 32.4+/-4.4 kg; age: 48.7+/-12.2 years) who exhibited stable weight on a 7 MJ/day diet during the first week of weight management were given a hypocaloric diet yielding daily energy deficit 2.5 MJ over the subsequent 3-week period. This treatment resulted in a mean weight loss of 3.80+/-1.64 kg. Correlation analysis revealed that baseline concentrations of several hormones were significantly associated either with a higher (free triiodothyronine, C-peptide, growth hormone, pancreatic polypeptide) or with a lower (insulin-like growth factor-I, cortisol, adiponectin, neuropeptide Y) reduction of anthropometric parameters in response to weight management. In a backward stepwise regression model age, initial BMI together with baseline levels of growth hormone, peptide YY, neuropetide Y and C-reactive protein predicted 49.8 % of the variability in weight loss. Psychobehavioral factors (items of the Eating Inventory, Beck Depression score) did not contribute to weight change induced by a well-controlled short-term weight reduction program.

INTRODUCTION: Self-perceived weight status among adolescents has been associated with weight-control behaviors. However, this relationship varies across weight status. OBJECTIVES: The aim of this study was to examine the effect of self-perceived weight status on dieting and unhealthy weight-control behaviors among Spanish male adolescents, across weight status. METHOD: Participants were 597 Spanish male adolescents (M = 13.94 years old, SD = 0.60). Body weight and height were measured in situ. Self-perceived weight status, dieting, and unhealthy weight-control behaviors were evaluated. RESULTS: The adolescents were inaccurate on estimating their weight status. Those who were overweight or obese, or who perceived themselves to be so, were more likely to report dieting and unhealthy weight-control behaviors. DISCUSSION: There is a need to promote healthier eating behaviors among adolescents, and to take into account the fact that self-perceived weight status may hinder the adoption of such behaviors.

PURPOSE: The purpose of this study was to analyze changes in the prevalence of weight reduction behaviors (WRBs) among European adolescents from 26 countries between 2001/2002 and 2017/2018. The impact of the perception of body weight on WLB was also analyzed, with particular attention being paid to overestimation. METHODS: The data of 639,194 European adolescents aged 11, 13, and 15 years who participated in the Health Behaviour in School-aged Children survey were analyzed. Age-standardized prevalence rates of WRB were estimated separately by survey round and gender for each country, using the overall 2017/2018 Health Behaviour in School-aged Children study population as the standard. Multivariate logistic regression analyses were used to assess WRB trends over time, adjusted for survey year, body mass index, body weight misperception, and family affluence and stratified by gender and age. RESULTS: In the 26 countries examined, the overall age-adjusted prevalence rates of WRB were 10.2% among boys and 18.0% among girls. The prevalence of WRB was higher for girls, but in the more recent surveys, gender differences in WRB decreased. There was a significant increase in the percentage of WRB among boys in most countries. Among girls, most countries did not experience significant changes. Increases in body mass index and overestimation of body weight were significant factors increasing the risk of WRB in both genders. CONCLUSIONS: The change in the prevalence of WRB by gender warrants greater attention from researchers and practitioners alike.

Kognitivně-behaviorální terapie (dále KBT) aplikovaná ve 12týdenních kurzech snižování nadváhy (KSN) společnosti STOB je součástí komplexního přístupu k terapii obezity v České republice. Cílem studie bylo ověřit celkovou efektivitu této terapie, v této práci jsme se zaměřili na dosažení a udržení váhových úbytků a změn ve stravovacích a pohybových návycích v časovém odstupu 2-7 let po ukončení kurzu. Průměrné snížení výchozí tělesné hmotnosti v KSN bylo 6,4 kg, tedy 7,4 % původní hmotnosti. Polovina účastníků kurzu byla v udržení váhových úbytků úspěšná.Po 2-7 letech činí průměrný úbytek téměř 3 % vstupní váhy, 40 % absolventů si udrželo alespoň 5% úbytek své vstupní váhy, dvě třetiny osob vážily v odstupu 2-7 let méně než při zahájení kurzu. Skladbu jídla pozměnilo vlivem kurzu 92 % sledovaných osob, přičemž z nich si 85 % správný návyk udržuje dodnes. Přiměřené množství a režim jídla: z absolventů kurzu, kteří si osvojili menší příjem potravin (94 %) si návyk uchovává 91 %, a z 61 %, kteří si osvojili správný režim jídla, si ho uchovalo 45 %. Změna skladby jídelníčku je zřejmě pro obézní menším problémem než změny v množství a režimu jídla. Neochuzuje je o požitek z jídla, lepší skladba stravy organismu prospívá, čímž je tato změna posilována. Pravidelnou pohybovou aktivitu zvýšilo 18 % absolventů kurzů (dnešních 46 % absolventů oproti 28 % těch, kdo měli pravidelný pohyb již před kurzem). Dosažení pravidelné pohybové aktivity je u obézních obtížnější než změna stravovaných návyků. Výsledky ukázaly, že kurzy snižování nadváhy jsou důležitou součástí komplexního přístupu k terapii obezity v České republice.
Cognitive-behavioral therapy (CBT) applied in 12-week courses of overweight reduction (COR) of the STOB society is a component of a complex approach to the treatment of obesity in the Czech Republic. The objective of the present study was to verify the overall effectiveness of that therapy; it has been focused on the attaining and sustaining of weight losses and changes in habits related to having meals and to physical exercise in a times lapse of 2-7 years after finishing the course. The mean loss in weight under CBT was 6.4 kg, i.e. 7.4% of the participants' initial weight. Half of the participants of the course were successful in sustaining their weight loss. After 2-7 years the average weight loss equals almost 3% of the initial weight,40% of the participants remained at a 5% weight loss, 2/3 of the subjects weighed less than 2-7 years ago at the beginning of the course. Due to the course, 92% of the subjects under follow-up changed the composition of their food, of whom 85% have kept an appropriate diet to this day. A commensurate amount and food regimen: of the 94% of participants who adopted a lesser food intake, 61% are holding on to that habit, and of the 81% who adopted an appropriate meal regimen, 45% are holding on to it. A change in the menue is apparently a lesser problem than in changing the amount of food and its regimen. It does not deprive them of enjoying food, a better composition of the food benefits the organism whereby that change is then strengthened. 18% of the participants increased their regular physical exercise (the present 46% of participants against the 28% who had regular exercise already before the course). Adopting regular physical exercise in the obese is more difficult than changing their dietary habits. The results have revealed that courses in weight reduction are an important component of a complex approach to the treatment of obesity in the Czech Republic.
Talk about food and eating behaviours invariably contains some reference to morality or accountability. However, there are very few studies that focus upon ;mundane dieting'. This research addresses this by examining 37.83 hours of naturally occurring interaction of how women construct and orient to food and their dieting practices within an everyday type setting. Group members produced accounts with reference to a moral evaluation, such as blame or culpability. It became apparent that both the group leaders and group members could not orient to their behaviour or food without reference to a moral or accountable framework. Implications for health promotion literature and programmes, along with weight management groups are considered.
The prevalence of obesity is increasing worldwide at an alarming rate in both developed and developing countries. Obesity is a chronic complex disease of multifactorial origin resulting from a long-term positive energy balance, in which both genetic and environmental factors are involved. Genetically prone individuals are the first to accumulate fat in the present obesogenic environment. Obesity increases the risks of type 2 diabetes, hypertension, cardiovascular disease, dyslipidemia, arthritis, and several cancers and reduces the average life expectancy. Implementation of effective strategies in prevention and management of obesity should become an important target in health care systems. Weight changes throughout life depend on the interaction of behavioral, genetic and environmental factors. Weight loss in response to weight management shows a wide range of interindividual variation which is largely influenced by genetic determinants. The strong control of weight loss by genotype was confirmed by twin and family studies. Recently, special attention has been paid to nutritional, hormonal, psychobehavioral and genetic factors which can predict the response to weight reduction programme. In this article currently available data on the role of obesity candidate gene polymorphisms in weight loss and maintenance are reviewed. It is believed that an elucidation of the genetic component in the prognosis of weight management could assist in the development of more effective and individually tailored therapeutic strategies.
