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 6.00–17.99 years 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 (6–12.99 years) 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 (13–17.99 years) 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.
