Characteristics of sleep patterns in adolescents in Siberia

The purpose of the research is to assess the main indicators of sleep patterns, taking into account gender, age and ethnicity in adolescents aged 12-18 in three large cities of Central Siberia: Krasnoyarsk (the studied ethnic group is Caucasians), Abakan (the studied ethnic groups is Khakass) and Kyzyl (the studied ethnic groups is Tuvans).The findings show Siberia adolescents have disturbance in sleep patterns: staying up late and an insufficient duration of sleep compared to age norms, which requires preventive measures. Moreover, these sleep disturbances are more pronounced in Krasnoyarsk (among Caucasians), than in Abakan (among Khakassians) and Kyzyl (among Tuvinians). Gender and age differences were identified as well: established sleep disorders are more pronounced among girls compared to boys, and in the older age group (15-18 years) compared to the younger group (11-14 years). All this requires preventive measures to regulate sleep patterns in schoolchildren.
