Comparative nutritional characteristics in schoolchildren with different nutritional status

Abstract

Aim. To assess the state of actual nutrition of children of early and middle school age with different nutritional status in the industrial center of Eastern Siberia. Materials and methods. The study included five hundred forty children, such as 145 7-10 years children in group I, 395 11-14 years children in group II. The criteria for dividing into subgroups were based on calculating the Z-scores of the body mass index by age. Analysis of the obtained results was performed using generally accepted statistical methods. Results. Analysis of the study results indicated a suboptimal ratio of nutrient critical for population health, protein, carbohydrate, polyunsaturated fatty acids (PUFA), omega-3 (ω-3), fat surplus, saturated fatty acids and added sugar. Dietary patterns of boys with high BMI had large values of the proportion of saturated fatty acids to total calories, which exceeded optimal physiological norms in group I by 52.22% and in group II by 37.68%. Girls of group I with a high BMI had a greater value of the proportion of added sugar to the calorie content of the food diet - 74.63%. Limitations of the study. Dietary information was obtained through questionnaires, all information was obtained from a one-moment examination. Conclusion. Some of the factors associated with impaired nutriome formation in the study children were imbalance in dietary patterns and surplus added sugars, which demonstrates the need to improve nutrition strategies at the regional level based on current meta-analyses.
