Relevance. Adipose tissue is considered an endocrine organ that produces several hormonally active substances, including the hormone leptin. This hormone plays a key role in regulating energy homeostasis and thermoregulation and may be involved in microevolutionary mechanisms of human adaptation to cold climates. The purpose of this work is to analyze the levels of leptin in the blood of young Yakut people living in the Republic of Sakha (Yakutia). Material and methods. The sample included Yakuts 18–30 years old with a total population of 281 people (186 women and 95 men). For each par-ticipant, the body mass index (BMI) was calculated, and the level of leptin in the blood serum was determined. Results. The average leptin level in women was 18.95±0.9 ng/ml, in men 6.57±0.88 ng/ml. In the Yakut population, previously known leptin sexual dimorphism (p
