Physical development of preschool children of Khanty-Mansiysky region by anthropometric indicators
The article presents the analysis of the physical development and nutritional status of254 children aged 3-6 y.o., attending preschool institutions in rural settlements (n = 80) and the centre ofthe district (DC, n = 174). According to the place ofresidence, samples are further referred to as rural and urban correspondingly. The evaluation ofanthropometric indicators was carried out by ranking individual values in Z-points. Growth retardation was detected in 7.5 % of the examined participants; underweight - in 9.1 %, overweight - in 16.5 %, including 5.1 % of obese children. Rural children demonstrated growth retardation (15 % versus 1.2 % in the district center), lack of body weight and exhaustion (12.6 versus 7.5 % in the village) more often (p <0.05). Overweight (including obesity) is noted in 20.1 % of children from the urban areas against 8.8 % in those from the villages. It is impossible to exclude the contribution ofthe anthropological factor to the differences between children from villages and urban areas, since 85 % of the examined rural children are indigenous northerners (Mansi, Khanty), whereas their share in the urban population is close to 5 %. The role ofethnic and social factors in the formation ofdifferences in height and body weight of children of the indigenous and alien population of Western Siberia requires further study.
