Against the background of increasing prevalence of cardiovascular pathology, monitoring of hemodynamic indicators in children and adolescents, assessment of adaptive capabilities during the study period in an educational organization are crucial tasks of modern medicine and prevention.
OBJECTIVE
To identify the features of hemodynamic indicators in modern school students, to determine tendencies in the dynamics of indicators on the basis of retrospective data analysis.
MATERIALS AND METHODS
Assessment of children’s physical development indicators was carried out on the results of a survey of 891 school students in Novosibirsk. Anthropometric and hemodynamic indicators were studied; adaptive potential was calculated. The retrospective data consisted of a sample of anthropometric and hemodynamic indicators of school students in Novosibirsk aged 7—17 years (n =4.599 children), obtained during medical examinations of school students performed in 1976 and 1997—2001. Statistical analysis was carried out using Excel spreadsheets of Statistica-10.0 package.
RESULTS
The mean values of the studied indicators, both in boys and girls corresponded to age norms, thus in 8.5% of children systolic pressure level was elevated with maximum values in 12 and 16 years age groups. Modern boys and girls are characterized by higher systolic and diastolic pressure values (by 4—6 mm Hg) and a higher heart rate compared to their peers living previously (p<0.05). It has been established in the assessment of adaptive potential that the stress of adaptive mechanisms is characteristic of most modern children (94.4%). In a large number of publications, the problem of prevalence of elevated blood pressure in modern children and adolescents is noted, as well as the decline in the proportion of children with satisfactory adaptive capabilities.
CONCLUSION
The performed analysis has revealed age-sex features of hemodynamic indicators in modern children and adolescents and has indicated a significant deterioration in the health of school students compared to their peers living more than 40 years ago.
