The research was conducted on 3644 students (1891 male respondents and 1753 female respondents). The goal of the research was to determine the degree and differences in the degree of nutrition and body composition between boys and girls from the 2nd to the 9th grade of elementary school. Based on the obtained results, a t-test for small independent samples, it was determined that there are no statistically significant differences between the male and female respondents in the level of nutrition and the skin fold on the stomach (suprailiac), and for basal metabolism, percentage of body fat, skin fold upper arms (triceps), skinfold on the back (subscapular), the differences are statistically significant. It was determined that out of a total of 1891 (52.00%) male respondents, 180 (9.52%) of them fall into the category of obese, 46 (2.43) boys into the category of excessive nutrition, 804 (42.52%) boys are normally well-nourished, while 861 (45.53 %) of boys malnourished. Out of a total of 1753 (48%) girls, 161 (9.18%) are obese, 38 (2.17%) are undernourished, 717 (40.90%) are normally well-nourished, while 837 (47.75%) are malnourished. Based on the body mass of students from the 2nd to the 9th grade of elementary school, recommendations for daily water intake (liters) are given. The recommendation for the average daily intake of water in liters for all boys is 1.45 and for girls 1.42. The obtained data indicate a problem today caused by bad lifestyle habits. Today's big problem is not only obesity among children but also malnutrition, which was most common among students from the 2nd to the 9th grade of elementary school. It is necessary to act preventively on time and perform more frequent measurements of elementary school-aged students to make changes and proper growth and development. It is necessary to motivate students more to play sports and change the quality and way of their lives. What we miss in childhood is hard to make up for later. [ABSTRACT FROM AUTHOR] |
