ABSTRACT: Over the recent years, the incidence of obesity is continuously rising. A research conducted in 2008-2009 on a representative sample of Czech population (n = 2,058) suggests that 23% of adult population of the Czech Republic are obese and 34% are overweight. This represents an increase of 5% in the number of obese people (17% vs. 22%), while the number of overweight remains practically the same (35% vs. 34%). A more significant shift in female waist circumference compared to male has also been shown. The incidence of hypertension in the evaluated sample was more than a two-fold higher in obese participants (48% vs. 21%) and as much as 3-fold higher in type 2 diabetes mellitus (7% vs. 20%). The risk of body weight increase is the highest between 50th and 59th year of age, where hypertension and diabetes are the most frequently diagnosed. The risk of obesity in adulthood is mostly carried over from childhood and more than 3/4 (77%) of those, who were overweight or obese as children, are in these categories as adults. Quality of life and satisfaction with own health is more related to BMI than age. Even though body weigh is increasing with the same amplitude in sportsman and physically active people, they are reaching lower final BMI due to their lower starting body weight. It is clear that physically active lifestyle in younger age is the best predictor of lower BMI in adult life. Consumption of secondary processed meat and lower consumption of fruit and vegetables are important factors in adulthood.

ABSTRACT: The aim of the study was to compare and evaluate psychological traits of eating behaviour assessed using the Eating Inventory (El) known also as the Three Factor Eating Questionnaire (TFEQ) and their relationship to body adiposity, health and social characteristic in a quota sample of Czech adults.
The sample included 1624 women and 1429 men who were interviewed individually by instructed investigators. The sample was quota representative--for gender, age, size of residential location, region and socioeconomic status in Czech adults. Anthropometric data were obtained together with socioeconomic and lifestyle information. Subjects filled out the EI. Health status was evaluated according to the data reported by GPs. Our results show, that women had higher restraint but lower disinhibition and hunger scores than men. Hunger and disinhibition were always strongly associated, whereas restraint was negatively related to the other two factors in men, and to hunger in women. In both men and women an educational level positively correlated with dietary restraint and negatively with hunger. However, significant negative relationship between educational level and disinhibition was revealed only in men. In backward stepwise regression analysis both dietary restraint and disinhibition predicted BMI and waist circumference. BMI and waist circumference were negatively related to restraint, but positively to disinhibition. Restraint and disinhibition were associated with prevalence of comorbidities in men, while disinhibition and hunger were in women. Individuals with high scoring in disinhibition score (upper quartile) exhibited significantly higher prevalence of hypertension, cardiovascular diseases and hyperlipidaemia than those who scored low (lower quartile). These relationships were most marked in middle-aged subjects.
Psychological traits of eating behaviour seem to have an important role in the development and clinical expression of body adiposity. Especially disinhibition is significantly associated with BMI and waist circumference and prevalence of several pathologies.

ABSTRACT: The purpose of this study was to estimate the change in overweight and obesity prevalence and the influence of socioeconomic
status and parental obesity on overweight and obesity of children and adolescents in the Czech Republic. The roles of family
history of obesity, dietary factors and physical activity were evaluated. The quota sample of 1,417 children and adolescents
aged 6.00–17.99years was examined in November 2005 as a part of the survey Lifestyle and Obesity. The quota sample was nationally
representative, and subjects were selected according to the gender, age, region, size of residential location and education
of parents. In the subjects weight, height and waist circumferences were measured and BMI was calculated. Food intake and
physical activity were estimated by food frequency and physical activity questionnaires. The results were compared with the
data from the 6th National Anthropological Survey of Children and Adolescents 2001, the Czech Republic. The data was evaluated
by Pearson’s chi-square test and by linear regression analysis with backward factor reduction. Enhancing prevalence of obesity
was found in younger age categories in comparison with the year 2001. Parental overweight and obesity significantly increased
the risk of overweight and obesity. BMI in children (6–12.99years) was associated with the intake of sweetened carbonated
drinks and potatoes including fried ones (positive association) and low-sugar carbonated drinks and physical activity (negative
association). In adolescents (13–17.99years) BMI was associated with parental obesity, fat meat intake, time spent on the
computer (positive association) and fish intake and physical activity (negative association). The results show an increase
in obesity prevalence in younger children in the Czech Republic. Parental obesity significantly enhanced the risk ratio of
obesity predominantly in adolescents.

ABSTRACT: To study the relationships between the Eating Inventory (EI) factors (restraint, disinhibition and hunger), body adiposity and prevalence of selected diseases in a quota sample of Czech adults.
The sample included 1429 men and 1624 women who were interviewed individually by trained investigators. The sample was quota representative--for gender, age, size of residential location, region and socioeconomic status in Czech adults. Anthropometric data, socioeconomic and lifestyle information were obtained. Subjects filled out the EI questionnaire. Physicians reported about subjects' morbidity.
Backward stepwise regression analysis revealed that restraint and disinhibition were significant predictors of body mass index (BMI) along with gender, age, parental obesity, weight loss attempts, present dieting and educational level. The same factors plus income predicted the waist circumference. BMI and waist circumference were negatively related to restraint but positively to disinhibition. According to logistic regression analysis restraint and disinhibition were significantly associated with hypertension, cardiovascular diseases and hyperlipidaemia. Diabetes was significantly related to restraint and hunger scores. The observed association between EI factors and diseases remained significant even when BMI and age were taken into account.
As shown in earlier studies, disinhibition was positively and restraint negatively associated with BMI and waist circumference. For the first time, factors of the EI were also identified as significant predictors of diseases characterizing the metabolic syndrome.
