Objective: to identify the sex differences in anthropometric and somatotypological parameters of the Gujarat youth people. Material and Methods. 147 male and 105 female 18-21 years old of the Gujarat ethnicity were studied. Anthropometry was carried out with a standard set of instruments. The following parameters were measured: body length, weight, transverse chest diameter, straight chest diameter, chest circumference at the moment of inhalation, chest circumference at the moment of exhalation, shoulder width, pelvic width. The indices of Pignet, Tanner, Erisman, Rees — Eisench, Quetelet II were calculated. Results. The body length of boys averaged 171.8±0.5 cm, for girls — 156.8±0.6 cm; the body weight of boys averaged 63.6±1.1 kg, girls — 53.37±1.09 kg; the value of the biacromial diameter in boys was 39.8±0.1 cm, in girls — 34.3±0.2 cm; the frontal diameter of the chest in boys was 26.9±0.2 cm, in girls — 23.0±0.2 cm; the circumference of the chest in boys at the time of the pause was 87,8±0,7 cm, in girls — 79.9±0.5 cm. The maximum circumference of the chest in boys and girls was determined to be 90.9±0.7 cm and 84.8±0.6 cm, respectively, minimum circumference of the chest in boys and girls — 82.9±0.7 and 76.2±0.6 cm, respectively. Conclusion. In both boys and girls, in most cases, an asthenic body type, narrow chest, and normal body weight were determined. According to the index of sexual dimorphism among the subjects as a whole, the mesomorphic body type was more often determined, the andromorphic type in parts was in second place and was 3.9 times more often detected in boys, the gynecomorphic type was 9.8 times more often detected in girls.
