Table 1. Weight-for-height and the BMI in the juvenile, adulthood I, and adulthood II periods in females of different constitutional groups (X + Sx; min-max)

According to our data, the leptosomatic group of body constitution was determined in 20%, while the mesosomatic group was noted in 32%, the megalosomatic group was recorded in 33% and indefinite group was established in 15% among the studied women. At the same time, during the transition from juvenile period to adulthood I period, and then to the adulthood II period, no fundamental changes in the constitutional features were observed, which corresponds to the concept of B. A. Nikityuk and V. P. Chetsov on the modification nature of these changes. The body length, weight, and the BMI are significantly depend on the type of body constitution (Table 1). Figure 1 show is showing schematics of age-related periodization of ontogenesis of women: juvenile, adulthood I and adulthood II.

基于本研究数据，受试女性群体中，瘦体型体质组（leptosomatic）占比20%，匀称体型体质组（mesosomatic）占32%，粗壮体型体质组（megalosomatic）占33%，体型未定组占15%。与此同时，在从少年期过渡至成年I期，再进入成年II期的个体发育进程中，受试女性的体质特征未出现根本性变化，这与B.A.尼基秋克（B. A. Nikityuk）与V.P.切佐夫（V. P. Chetsov）提出的此类变化具有修饰性本质的学术观点相符。身高、体重与身体质量指数（BMI）均与体质类型存在显著相关性（见表1）。图1为女性个体发育的年龄分期示意图，包含少年期、成年I期与成年II期三个阶段。
