ANALYSIS OF CHANGES IN HEIGHT AND WEIGHT MARKS IN YOUNGER ADOLESCENTS IN THE PERIOD FROM 1970 TO 2020
Abstract
The study was conducted on a sample of 200 subjects of both sexes, with the aim to indicate the trend of changes in height and body weight, as well as the level of nutrition in subjects with an average age of 13.6 years compared to the results of previous studies. For the purposes of comparative analysis, the survey included data obtained from studies conducted over the past 50 years, the subject of which was body height and body mass as the main morphological characteristics of the human body. According to the obtained results, it was determined that the acceleration phenomenon was present in the analyzed time period. Extremely body height was observed in both boys of (13.8 cm) and girls (11.0 cm) as well as body weight in boys (18.8 kg) and girls (13.7kg). Body mass index (BMI) results indicate a level of overweight in the sub-sample of boys (21.6) and a tendency toward the same category of nutrition in the sub-sample of girls (20.7). The main causes of the trend of marked changes in the analyzed morphological characteristics are: malnutrition, insufficient physical activity and overuse of modern technological means, as key characteristics of the present way of life of children and young people.
