Evaluation of the anthropometric nutritional status of pupils in primary schools in Varna

Въведение: Училищната възраст е рисков период по отношение нарушения в хранителното поведение. Както затлъстяването, така и недохранването могат да имат негативни последици за здравето. Цел: Да се анализира антропометричният хранителен статус на ученици от начален курс на обучение от град Варна. Материали и методи: През учебната 2011/2012 г. в гр. Варна е проучен антропометричният статус на ученици 1-4 клас. Обхванати са 3091 деца (1565 момчета и 1526 момичета). Със съдействието на училищните лекари са измерени ръстът и телесната маса. Изчислен е ИТМ, чиито стойности са сравнени със стандартите на СЗО за съответната възраст от 2006 г. Данните са обработени чрез вариационен и алтернативен анализ. За сравнение на резултатите е използван критерият на Стюдънт-Фишер. Статистическата достоверност е определена при ниво на значимост p<0,05. Резултати: Индексът ИТМ - за възраст, показва нормални стойности при над 50% от учениците. Относителният дял на учениците от втори и трети клас със свръхтегло според ИТМ е достоверно по-висок от този на първокласниците и при двата пола. При учениците от различните възрастови групи не установяваме достоверни разлики по отношение наличието на затлъстяване според ИТМ. То е достоверно по-често при момчетата спрямо момиче тата на същата възраст. С поднормено тегло и недохранване са под 5% от измерените ученици. Най-висок е делът на децата с недохранване в І клас (n=12; 1.23%), a най-нисък - в ІV клас (n=12; 0.24%). Заключение: При целодневно обучение в началния курс трябва да се създадат условия, профилактиращи натрупването на телесна маса.Introduction: The educational period carries a high risk of imbalanced nutritional behavior. Obesity, as well as undernourishment, may be extremely dangerous for the health. Aim: To analyze the anthropometric nutritional status of pupils in primary schools in Varna City. Materials and Methods: During the school year 2011/2012 the anthropometric nutritional status of pupils from first to fourth grade was analyzed. The study covered 3091 children (1565 boys and 1526 girls). With the help of the school doctors their height and body mass was measured. BMI was calculated and its rate compared with the WHO standards for this age from 2006. The data was processed via variance and alternative analysis. To compare the results, the Stu-dent-Fisher criterion was used. The Statistical Reliability was determined with significance p<0.05. Results: The Body Mass Index (BMI) reveals normal values with over 50% of the pupils. The relative part of pupils in second and third grade with obesity according to BMI is significantly higher than the one in first grade with both boys and girls. Among the pupils from different age groups, a significant difference in the percent of obesity according to BMI cannot be determined. The latter is significantly higher among boys compared to girls of the same age. Children with underweight and undernourishment are less than 5% of all measured. The part of children with undernourishment is the highest among the first-graders (n=12; 1.23%), and the lowest among the fourth-graders (n=12; 0.24%).Conclusion: In full-time education in primary schools, conditions should be created to prevent the accumulation of body mass

Effect of Cultivation Conditions on the Growing Activity of Winter Barley Genotypes

In the period 2018-2020 in the Institute of Agriculture - Karnobat, Bulgaria the influence of growing conditions on the growth activity of winter barley genotypes was studied. The experiments were performed in field and laboratory experiments. In a field multifactorial experiment with 4 fertilization variants (N0%253A N8%253A N12%253A N16) and three sowing rates (250, 350 and 450 germinating seeds) the barley varieties Kuber, Sayra, Zemela and Bozhin were grown. The obtained seeds from the different variants were studied in a laboratory experiment by the method of rolls. From each variant 20 seeds are laid in 3 repetitions on filter paper. The rolls are immersed in water and after 10 days the length of the first leaf, the length of the coleoptile, the number of roots and their length are taken into account. It was found that there are proven differences in the indicators in the studied genotypes. On average for the years of study, the length of the first leaf and the length of the roots is the largest for the seeds obtained in the variant at a sowing rate of 450 germinating seeds and N8. With the largest length of coleoptile and the largest number of roots are the seeds of the variant with a sowing rate of 250 germinating seeds and N8. Analysis of the variant shows that the length of the first leaf, the coleoptile and the number of roots depend on the genotype. The strongest influence on the length of the roots have the conditions of the year. The interaction between the two factors strongly influences all the studied indicators. The interaction between the year, genotype, sowing rate and fertilization also has a great influence on the indicators of the length of the first leaf, coleoptile and roots
