Aim. To study the nutrient and energy intake of modern university students. Materials and methods. 244 students aged 18–23 enrolled in specialist degree programmes were surveyed using a 24-hour dietary recall method adapted for online Google form surveying. The food intake was analysed based on the following aspects: meal frequency, intervals between meals and energy intake.Results. According to the obtained results, 38.93 ± 3.12% of the respondents follow a 3–4 meal-a-day diet, with 3 main meals (breakfast, lunch and dinner) adhered by 71.31 ± 2.9% of students. In comparison with male respondents, female students were found to be more likely to keep main meals (74.87 ± 3.17% versus 59.65 ± 6.50%, χ2 = 4.94, p = 0.027). Additional meals (second breakfast, afternoon tea, overnight snack) were observed in 64.75 ± 3.06% of the students, with this share being significantly larger among male students (78.95 ± 5.40% versus 60.43 ± 3.58%, χ2 = 6.56, p = 0.011). About 68.44 ± 2.98% of the respondents reported long intervals between meals, which was found to be more typical of female students (71.66 ± 3.30% versus 56.14 ± 6.57%, χ2 = 4.84, p = 0.028). The energy intake of young people was established to correspond to the recommended norm in 27.40 ± 3.69% of cases.Conclusions. The findings emphasize the importance of developing healthy eating habits in modern students, which can contribute to improving their health and increasing their educational performance.

Chronic generalized periodontitis takes one of the leading places in the structure of dental diseases. Inflammatory periodontal disease is one of the most common complications of diabetes. An important role in the progression of periodontitis in type II diabetes mellitus (T2DM) belongs to disorders of the immune system that affect the supportive/retaining complex of the tooth. Inflammation of periodontal tissues which occurs in the patients with carbohydrate metabolism disorders is characterized by a more severe course, which worsens the condition and quality of life of patients with T2DM thus leading to tooth loss. In this regard, the immunological aspects of developing periodontal pathology under conditions of carbohydrate metabolism disorders are of great interest. Purpose of our study included comparative assessment of local TNF, TNF, IFN, IL-1, IL- 12, IL-17A levels in patients with periodontitis with and without carbohydrate metabolism disorders (type II diabetes mellitus), as well as in patients with type II diabetes mellitus without signs of periodontitis. 127 patients were examined, aged 30 to 59 years. The patients were divided into 3 groups, i.e., group I included patients suffering from periodontitis of varying severity without known comorbidities (47 persons); Group II consisted of patients with T2DM and periodontitis of varying severity (49 persons); Group III included patients with T2DM without symptoms of periodontitis (30 persons). The control group consisted of 30 practically healthy volunteers, matched to the patients for age and sex. Saliva specimens were used for laboratory studies. The levels of TNF, TNF, IFN, IL-1, IL-12, IL-17А were determined by ELISA sandwich technique, with specific reagents purchased from RD Diagnostics Inc (USA). A significant increase in the IL-1, TNF, IFN and IL-17A levels was found in patients of all groups compared with controls. At the same time, the increased concentrations of IFN, IL-1, IL-17A correlated with increase in periodontitis severity in the patients of both groups. Decreased TNF levels in saliva samples were revealed in the patients from almost all groups, regardless of the periodontitis severity. Significantly increased levels of IL-12 (p40 subunit) were recorded in saliva of the persons from group II and III when compared with controls and the group without diabetes mellitus.

Iron contamination of drinking water in municipal water supply systems is recognized as a risk factor for impairment of public health. Tap water in the city of Vladivostok has increased iron content (more 0.8 mg /l). The aim of this study was the medical assessment of the actual average daily dose (AADD) of iron consumed by Vladivostok residents with all sources its per oral administration. Present study was performed in February 2017. A random sample of 183 adolescents from 14 to 17 years old from Vladivostok municipal schools was investigated. Daily consumption of tap water, 85 trade names of bottled water, 21 groups of food products and dishes were studied by questionnaire method. The iron content in foods and drinking waters was taken according to the national reference tables and laboratory data. It was established that the iron AADD values among adolescent population were equal about 17 mg/day, what is harmless to the health. At the same time the frequency of iron intake deficiency was 18.37 (boys) and 64.58 (girls) cases per 100 people. It has been found that, against the background of an excessive of the iron content in tap water (up to 2.7 MAC) according to organoleptic limiting sign of harmfulness, the occurrence of deficit of its consumption in boys and girls is due to low consumption levels of foods with the highly bioavailable iron: eggs, animal meat and poultry meat.
