Age estimation of Russian individuals by teeth using the London Atlas / Análise da estimativa de idade em indivíduos russos utilizando a metodologia London Atlas

Knowing an individual's age is necessary for several situations, both in the living and the deceased. The London Atlas uses dental development and eruption to estimate age. Testing the method in different populations is necessary to assess its performance. This study aimed to assess the performance of the London Atlas method in a Russian sample using panoramic radiographs. A sample of 703 panoramic radiographs of Russian individuals (n = 405 females, 57.61% and n = 298 males, 42.39%) with ages between 8 and 23 years were analyzed. The results showed overestimation in individuals from 8 to 14 years and underestimation from 15 to 23 years. The mean difference between estimated and chronological ages did not exceed 0.7 years among individuals with ages below 19 years. The difference increased to over three years in individuals from 20 to 23 years. Statistically significant differences were found between females and males between 17 and 18 years (p<0.05). The London Atlas is suitable for Russian children and adolescents aged between 8 and 19 years; however, it showed unsatisfactory results for application in individuals over 20 years (AU).

Conhecer a idade de um indivíduo, vivo ou morto, é essencial em diversas situações. O método London Atlas utiliza desenvolvimento e erupção dentais para estimar a idade. Testar o método em diferentes populações é importante para avaliar sua performance. Esse estudo objetivou analisar o desempenho do London Atlas em uma amostra de origem russa, utilizando radiografias panorâmicas. Uma amostra de 703 indivíduos russos (n = 405 mulheres, 57,61% e n = 298 homens, 42,39%), com idades entre 8 e 23 anos foram analisadas. Resultados obtidos mostram uma superestimação em indivíduos de 8 a 14 anos e subestimação nos grupos de 15 a 23 anos. A diferença média entre idades estimadas e reais não excederam o valor de 0,7 anos nos indivíduos com idade abaixo de 19 anos. Essa diferença aumentou em até três anos em indivíduos de 20 a 23 anos. Diferenças estatisticamente significantes foram encontradas entre homens e mulheres com 17 e 18 anos (p<0,05). O London Atlas é adequado para crianças e adolescentes de origem russa, com idades de 8 a 19 anos. No entanto, observou-se resultados insatisfatórios para sua aplicação em indivíduos acima de 20 anos (AU).

Complex Method For Assessing The Psychophysiological State Of The Arctic Zone Of Russia Residents

@#Objectives: For the timely detection of the people's health problems in the Arctic zone we used in parallel methods of heart rhythm variability (HRV) and gas-discharge visualization (GDV). Subjects: A group of 120 volunteers - male residents of Murmansk region in Russia's Arctic zone divided into two age groups: 58 people aged 31.54±5.69 and 62 people aged 54.31±7.26 participated in a study. Results: Age-related differences in the associated indicators of GDV grams and HRV were shown with many correlations between the two methods. Conclusions: The results obtained testify to a deep interrelation and coherence of the system energetic processes of metabolism in the human body, and the fact that the human body is an integral complex hierarchical system of information-energetic interactions, the scientific study, and understanding of which can lead to further advances in both fundamental pieces of knowledges and contribute to the optimization of diagnosis, treatment, and prevention of non-infectious diseases. The results obtained confirm the validity of using the selected set of methods as promising methods for evaluating the human body's psychophysiological state for further practical implementation in practical health care.

Obesity and Physical Fitness among Moscow Schoolchildren: 6-years Follow-up.

Aim: To assess study the prevalence of obesity and physical fitness among Moscow schoolchildren. Subjects and Methods: During the 2004-5, 2007-8, and 2010-11 school years, about 20% of Moscow schoolchildren were studied in all districts of the town. Both anthropometric and physical fitness data were collected. Obesity was determined according to international recommendations, observed physical fitness in accordance with national norms. Results: During the observation period the number of schoolchildren with obesity increased 1.5 times and reached about 20%. Obesity was observed 1.6 times more frequently in boys than in girls. In the 2004-5 school years a total of 66% of boys and 58% of girls undertook vigorous physical fitness. By the 2010-11 school years the number of schoolchildren undertaking vigorous physical fitness had decreased by 10%. The number of boys undertaking vigorous physical fitness was 1.8 times lower in the obesity group than in the normal weight group. The corresponding difference for girls was 1.4 times. Conclusion: Findings of this study suggest an increase in the prevalence of obesity among Moscow schoolchildren which could be attributed to their low level of physical fitness.
