Are Dietary Intakes Related to Obesity in Children?

AIM The purpose of this study was to report obesity status and identify any dietary substances that may be related to obesity in healthy school children from Northern Greece. METHODS Four hundred and twenty-five (n = 425) children were randomly selected to participate in the study. A 24-h recall of three days (two weekdays and one weekend day) was used to analyze the dietary data of the subjects. RESULTS Out of 425 subjects, 146 (34.3%) of them were found to be overweight and obese. Energy, protein, carbohydrate and thiamin intake was statistically positively correlated with obesity while dietary iron intake was statistically negatively correlated with obesity. Multivariate logistic regression analysis showed that the children with dietary iron deficiency were 1.128 (95% CI: 0.002, 0.161 P < 0.031) times more likely of being obese compared to the normal group after adjustment for energy intake. CONCLUSIONS Although most of the dietary intakes of our subjects were adequate, special consideration should be given to energy, carbohydrate, protein, and sugar and iron intake especially and its relation to obesity. Furthermore, additional studies are required to investigate any possible relation of low dietary iron consumption and obesity.
