Установить этнические различия в линейных параметрах длины проксимальных фаланг (ПФ) и ширины диафизов ПФ у детей и подростков мужского пола Таджикистана и Западной Индии. Разработать регрессионные уравнения для определения возраста по размерам ПФ.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследовано 366 рентгенограмм правой кисти лиц мужского пола Таджикистана (г. Канибадам) и Западной Индии (г. Мумбаи) 6–17 лет. Зависимость возраста от длины ПФ (ДлПФ) и ширины диафиза ПФ (ШПФ) изучалась с помощью парного линейного регрессионного анализа и корреляционного анализа. Влияние возраста на ДлПФ, ШПФ определялось с помощью однофакторного дисперсионного анализа, критерия Краскела – Уоллиса и последующего post-hoc анализа по возрастам.</p></sec><sec><title>Результаты</title><p>Результаты. ДлПФ и ШПФ представителей Таджикистана и Индии коррелируют с возрастом, коэффициент корреляции больше 0,5. В обеих этнических группах коэффициенты корреляции между возрастом и ДлПФ превышали 0,8. Коэффициент корреляции возраста и ШПФ у таджиков колеблется в диапазоне 0,68–0,77, у индийцев – 0,58–0,69. Построены парные линейные регрессионные модели для прогноза возраста по ДлПФ с коэффициентом детерминации R2, большим 0,6, за исключением ДлПФ5 для таджиков. ДлПФ5 для таджиков и значения ШПФ для обеих этнических групп показали слабые R2 (0,35–0,53). Найдено 11 значимых различий между равновозрастными этническими группами по ДлПФ и ШПФ.</p></sec><sec><title>Заключение</title><p>Заключение. ДлПФ является лучшим предиктором возраста, чем ширина диафиза. Самым надежным предиктором для обеих национальностей является ДлПФ2. Увеличение параметров ПФ происходит неравномерно с возрастом. Интенсивный рост ПФ наблюдается преимущественно в интервале 12–15 лет. Больше всего значимых отличий ДлПФ и ШПФ между этническими группами найдено в 8 и 15–16 лет, при этом ДлПФ и ШПФ таджиков превышали индийские.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of the study was (a) to establish ethnicity-specific differences in such morphological parameters of the proximal phalanges (PP) as the bone length and the width of diaphysis in male children and adolescents from Tajikistan and Western India and (b) to develop regression equations for determining their age based on the size of the PP.</p><sec><title>Materials and methods</title><p>Materials and methods. Three hundred and sixty-two X-ray images of the right hand of male subjects were examined. All subjects originated from Tajikistan and Mumbai, India, and aged from 6 to 17 years. The  relationship between the subjects’ age and the length of the PP (LPP) and the width of the diaphysis of the PP (WPP) was investigated using a simple linear regression and correlation analysis. The LPP and WPP dependence on age was determined using one-way ANOVA and the Kruskal–Wallis test followed by post-hoc analysis by age groups.</p></sec><sec><title>Results</title><p>Results. LPP and WPP of the subjects from Tajikistan and India correlated with age, with the correlation  coefficient exceeding 0.5. In both ethnic groups, the correlation coefficients for LPP vs. age was greater than  0.8. The correlation coefficient for WPP vs age ranged from 0.68 to 0.77 in Tajiks and from 0.58 to 0.69 in Indians. Simple linear regression models were developed to predict the age from LPP (R2 &gt; 0.6), except for LPP 5 for Tajiks. The LPP 5 values in Tajiks and the WPP values in both ethnic groups showed weak R2, which ranged from 0.35 to 0.53. Eleven significant differences were identified between the ethnic groups of the same age with respect to LPP and WPP.</p></sec><sec><title>Conclusion</title><p>Conclusion. PP length was a better age predictor than the diaphysis width. The most reliable predictor for both ethnic groups was LPP 2. The PP parameters did not change uniformly over time. The PP demonstrated especially intensive growth between 12 and 15 years. The most significant differences in LPP and WPP between two ethnic groups were found for the ages of 8 and 15–16 years, with LPP and WPP in Tajiks exceeding those in Indians. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>кисть</kwd><kwd>фаланги</kwd><kwd>идентификация по костям</kwd><kwd>определение возраста</kwd><kwd>этнические особенности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hand</kwd><kwd>phalanges</kwd><kwd>identification from bones</kwd><kwd>age estimation</kwd><kwd>ethnic features</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Nemade K.S., Kamdi N.Y., Parchand M.P.
