Aim The main purpose of the study was to analyze the changes in the prevalence of underweight, overweight, and obesity among Czech children and adolescents aged 3-18 within the last 50 years. The secondary purpose

SUMMARYThe prevalence of child obesity in the Czech Republic has increased in the last several years, especially among school-aged children. While obesity trends are closely monitored in the Czech Republic, very little is known about the dietary habits and exercise behaviors of Czech children. The purpose of this study was to evaluate nutrient intakes and physical activity, as well as identify predictors of BMI-for-age in a sample of Czech school-aged children. Ninety-seven fourth, fi fth and sixth graders and their parents from two large Czech cities participated in the study. Two 24-hour recalls provided total amount of energy, fat, percentage of energy derived from fat, dietary fi ber, and servings of fruits and vegetables. Physical activity was measured by the Self-administered Physical Activity Checklist (SAPAC). Children consumed less energy and dietary fi ber than suggested by Czech dietary recommendations. The proportion of energy that children consumed from fat was 28.5%. Children consumed 1.4 cups of fruit and 1.2 cups of vegetables. Children's physical activity levels fell within the current recommendations. Age was the only signifi cant predictor of higher BMI-for-age. Poor dietary quality may be responsible for increasing rates of child obesity in the Czech Republic. Nutritional professionals in the Czech Republic should focus on increasing consumption of fruits, vegetables, and other high-fi ber foods in order to reduce the risk for overweight among Czech children.

The purpose of this study was to determine the relation between serum and dietary antioxidants, and C-reactive protein (CRP) concentrations in middle-aged and older individuals at risk for cardiovascular disease. We used data from adults aged > or = 40 at increased risk for cardiovascular disease selected from the NHANES III database. The relation between serum and dietary antioxidants, and CRP concentrations was examined using multiple logistic regression analysis. Serum antioxidants and CVD risk factors were significant predictors of detectable CRP concentrations (R2 = 0.07; p < 0.001). Dietary antioxidants (except vitamin C) were not significant predictors of detectable CRP concentrations.
