The aim of this study was to explore the differences in nutritional status and dietary intakes in 12~17 year-old children living in urban (Zagreb) and the rural (Sinj and Drniš) area of Croatia. A validated food frequency questionnaire was used to assess dietary intake. For each participant, body weight and body height were measured and bioelectrical impedance was used to estimate the body fat percentage. There was an overall of 310 children included: 105 (33.9%) from urban area and 205 (66.1%) from rural area; 191 (61.6%) were female with a mean age 14.9 (range 12~17) years. When adjusted for age and gender, there was no statistically significant difference in body mass index for age Z-scores between urban and rural parts (0.23±0.07 vs. 0.30±1.15; P=0.650) or in average daily energy intake (2,479.2±1,111.2 kcal vs. 2,338.2±920.2 kcal; P=0.702). There was a statistically significant difference in nutritional status between genders, with a higher percentage of boys being overweight or obese compared to girls. When combined, 'Fast food' and 'Snacks' were major contributors to the total energy intake for both areas. The mean contribution of 'Fast food' to total energy intake was significantly higher in the urban area. The prevalence of obesity among Croatian children is high and unrelated to the urban/rural setting, which could be partially explained by the high intake of 'Fast food' and 'Snacks'.
