Background: The article shows that the development of obesity and associated health disorders is directly related to the changes in eating behavior (EB) and the psychoemotional state. However, the considered studies were carried out in obese patients of medical institutions only. The research in young people focuses mainly on the sociological and psychological aspects of EB.Aim: To study the psychological characteristics, eating behavior features and their relationship with the indicators of actual nutrition and the body composition in young men.Materials and methods: A multicenter, cross-sectional sample survey of young men aged 17 to 21 was performed. A survey of violations of the EB was carried out, on the basis of which 5 groups of young men were formed. Group 1 (comparison) consisted of young men without violations of the EB. Group 2 consisted of young men with impaired emotiogenic EB. Group 3 consisted of boys with violations of the restrictive PP; group 4 — young men with impaired external EB; group 5 — young men with a combination of impairment of emotionogenic and restrictive EB. We used the Dutch DEBQ questionnaire to study the types of eating behavior. The current mental state of the testees was evaluated by a clinical and psychological test — Symptom Checklist-90-Revised (SCL-90-R). The body composition was assessed with the ABC-01 «Medass» bioimpedansometry device. The «Analysis of the human nutritional state” computer program was applied to estimate the actual nutrition by the frequency analysis method.Results: The study included 96 volunteers. Young men with impaired external EB feature an increase in the daily average energy consumption, which resulted in an increase in BFM%. In young people with eating disorders, an increase in scores on the «Somatization», «Obsession-compulsion», and «Anxiety» scales as compared to the reference valuesis testified. The depression level in young men correlated with the severity of emotiogenic eating behavior (r = 0.455, p <0.001).However, it is associated with the severity of external EB to a greater extent (r = 0.608, p <0.001). On the contrary, the anxiety level more strongly correlated with the severity of emotiogenic EB (r = 0.575, p <0.001) rather than of external EB type (r = 0.391, p <0.001).Conclusion: EB disorders in young men are associated with psychophysiological features, eating disorders accounting for the accumulation of adipose tissue in the body.

Meteosensitivity determines the state of human health. It is reflected in all areas of activity. The cardiovascular system is one of the most sensitive to changes in environmental factors. Its form is considered as the most vulnerable element in professional adaptation. The study aims to determine whether the state of the cardiovascular system depends on abiotic environmental factors in healthy people during industrial training. Additionally, we tried to determine whether the state of the cardiovascular system influences the quality of developed professional skills. We examined 84 girls between 17 and 21 during 26 weeks of practical training in the first and second shifts. We recorded their blood pressure and heart rate, and also calculated the Kerdo vegetative index. We monitored such abiotic factors as air temperature, precipitation, cloud cover, wind direction, velocity, and air pressure. We also considered the day of the week, time of the day, date, daylight hours, and Wolf relative number. The data were subject to correlation analysis. The results demonstrate that the mean group values of blood circulation indicators in vocational school students correlate to adaptive biorhythms, solar activity, weather, and environmental factors. The state of the students’ cardiovascular system affects the quality of mastering professional skills.

ФГБОУ ВО «Алтайский государственный университет», г. Барнаул Введение: Несмотря на пристальное внимание к проблеме питания студенческой молодежи, влияние фактора нарушений пищевого поведения (ПП) остается недостаточно изученным. Цель: Изучить ПП студенческой молодежи -жителей промышленного центра Западной Сибири г. Барнаула и факторы, его формирующие. Методы: Анкетирование с целью изучения нутриционного статуса, Голландский опросник пищевого поведения (DEBQ). Результаты: Методом кластерного анализа были выделены четыре стереотипа пищевого поведения (СПП): рациональный (СПП1), преимущественно углеводный (СПП2), гиперкалорийный (СПП3) и гипокалорийный (СПП4). Максимально представлен СПП4 (57,7 %), на втором месте -СПП2 (31,8 %), 8,7 % обследованных молодых людей имели СПП1. Наименее распространенным был СПП3 (1,7 %). Изучено влияние на формирование СПП таких факторов, как пол, образование, достаточность материальных средств, информированность в вопросах питания, семейное положение и субъективная оценка состояния здоровья, нарушение ПП. Выявлена более высокая доля лиц с нарушениями ограничительного ПП в четвертом кластере (СПП4). Вероятность придерживаться гипокалорийного стереотипа питания у лиц с нарушениями ограничительного ПП в два раза выше (Risk = 2,083, χ 2 = 152,05, df = 1, р < 0,001), чем у всех остальных обследованных лиц. Выводы. Рацион питания обследованных молодых людей характеризуется дефицитом биологически ценных компонентов (мясо, молоко и молочные продукты). Среди большинства опрошенных респондентов определена углеводная модель питания, две трети обследованных нами молодых людей придерживаются гипокалорийного стереотипа питания. К факторам, наиболее влияющим на формирование стереотипа питания, относятся пол, достаточность материальных средств, семейное положение, субъективная оценка состояния здоровья и нарушения пищевого поведения.Ключевые слова: стереотип пищевого поведения, нарушение пищевого поведения, индекс массы тела
