Puberty Start of Girls Residing in Urban and Rural Areas of the Turkestan Region

Our research has shown that the maximum changes of somatometric indices in girls of observed groups began in the early adolescence and continued until the end of adulting. All physical parameters during the height of their increase in the early adolescence were lower in rural adolescents than in urban peers. In the childhood period no differences in the formulas of sexual development were found in girls in rural and urban areas. In the early adolescence, the formula for urban adolescents was: P_0.1Ax_1.2Ma_1–4Me+, for adolescents from the village—P₀Ax₁Ma_1–3Me+. In late adolescence, there was a decrease in the growth rate of physical parameters, while signs of puberty, on the contrary, increased. In late adolescence, all sexual characteristics are detected in adolescents of both groups, P_2–4Ax_3–4Ma_2–4Me+ and, accordingly, in adolescents from the village P_2–4Ax_2–4Ma_1–3Me+. And the ending of the reproductive period had its differences in rural and urban women. For the urban women, menopause age consisted of 46.80 ± 0.09, and for the rural citizens was 48.23 ± 0.11. It can be assumed that the great significance in development processes belongs to such factors as poor or deficient nutrition of children in the rural area, excessive physical activity as a result of participation in agricultural work and bad medical assistance of the girls’ adolescent period in the rural area. The research data showed the beginning of the menopause was earlier in the urban citizens.
