Influence of serological markers of blood groups upon the development of visual memory in high schoolers and students

The aim: To investigate the influence of serological markers of blood groups of the AB0 system upon the development of short-term visual memory in high schoolers and students. Materials and methods: The research involved 13-16-year-old high schoolers (boys) (n = 139) who were involved in various sports: group A – speed and strength sports (n = 74); group B – endurance sports (n = 65). The control group consisted of 13-16-year-old high schoolers (n = 106) and 17-20-year-old students (n = 212) who were not engaged in sports. The study of short-term visual memory was conducted using the“Memory for geometric shapes”method. Results: It was found that high schoolers and students with the 0(I) blood group have the best associative coupling with the properties of short-term visual memory. Conclusions: The use of serological markers of blood groups according to the AB0 system is possible in the genetic prediction of the development of visual memory in high schoolers and students. Herewith, the associative coupling is more pronounced in juvenility than in adolescence

The Impact of Nutritional Quality on the Students’ Health

Aim: To study the nutritional quality and its impact on the health of the students of higher education institutions. Material and methods: 647 students were interviewed. A questionnaire, which contains 17 questions and is aimed at studying the quality of students’ nutrition, was created by authors. Experimental (EG, n = 60) and control (CG, n = 60) groups were formed. The EG included the students whose diet was rational while studying, the CG included the students whose diet was irrational. The level of students’ health was examined at the end of studying according to the methodology of professor G.L. Apanasenko. Results: It was found that only 30.6% of students ate 3-4 times a day, 14.4% – twice a day, 49.8% did not follow any dietary regimen, and 7.9% of students would not eat breakfast at al 43.7% of male students and 53.3% of female students did not follow a dietary regimen at all. A comparative analysis of the physical health of students of EG and CG showed that among both male and female students, the students whose diet was rational had significantly better (p<0.001) level of health. Conclusions: It was determined that the majority of students had low nutritional quality while studying: nutrition was irrational, incomplete, and not varied. This does not contribute to a healthy lifestyle of modern students and can negatively affect the efficiency of their future professional activities
