Aim To evaluate whether the health‐related quality‐of‐life (HRQoL) scores would be different for adolescents with menstrual problems as compared to those with normal menstruation after taking into account clinical, socio‐demographic and life‐style factors. Methods The Paediatric Quality of Life Inventory 4.0 scale was used to assess HRQoL in 126 schoolgirls of 16 ± 0.4 years old. The adolescents completed semi‐structured questionnaires containing information on social and demographic characteristics, life‐style features and menstrual questionnaires that included the following: age of menstruation, menstrual cycle length, duration of production, the number of pads used per day, menstrual pain and drug administration to relieve dysmenorrhea. The menstrual problems were classified into three main groups: dysmenorrhoea, oligomenorrhoea, and heavy menstrual bleeding. Anthropometric measurements were performed by a physician. Medical history was obtained from school medical charts. Results Ninety‐seven (77%) girls had menstrual problems. Dysmenorrhoea (n = 92, 73%) was the most frequent of these, followed by oligomenorrhoea (n = 13, 10.3%) and heavy menstrual bleeding (n = 6, 4.8%). Thirteen (10.3%) girls had combined disorders. A multivariate analysis adjusted for life‐style factors found an independent association of any menstrual problems, oligomenorrhoea and dysmenorrhoea with low HRQoL scores in the emotional functioning domain. For adolescents with oligomenorrhoea, an association with low total scale scores was also shown but it did not reach statistical significance. Conclusion The prevalence of menstrual problems is high among schoolgirls. Medical professionals working with adolescents should know that girls with menstrual problems are highly likely to have a poor quality of life, especially those with oligomenorrhoea.

The most of the health-related quality of life (HRQOL) studies are conducted to assess the psychosocial consequences of diseases. However, there is evidence that HFQOL is affected not only by the presence of disease, but also by a wide range of other factors. The purpose of the study was to determine the most significant socio-demographic and behavioral factors associated with quality of life in adolescents who are school students. Materials and methods of the research: a continuous single-stage study was conducted, which included school students of the 10th grade in the city of Irkutsk, Russia. The HLQOL was assessed by adolescent self-reports by PedsQL™ Measurement Model version 4.0 (Lyon, France) for adolescents aged 13 to 18 years old. Semi-structured questionnaires were used to obtain information on socio-demographic characteristics and lifestyle factors. Information about diseases was obtained by copying from schoolchildren’s medical records. Results: The study included 463 adolescents (174 (37.6%) males). According to the results of one-way regression analysis, the low (≤ 25th percentile) HLQOL in the 10th-graders was associated with female gender - OR 3.3 (CI 1.95–5.63), the presence of a chronic disease - OR 1.6 (CI 1 03-2.47), poor living conditions - OR 2.4 (CI 1.4-4.16), alcohol abuse in the family - OR 2.8 (CI 1.07-7.27), time spent with a personal computer - OR 1.4 (CI 1.24–1.57). The impact on quality of life was shown for organized sports - OR 0.6 (CI 0.35–0.9), and distant walking - OR 0.6 (CI 0.46–0.83). In a multivariate analysis, the significance of association with HFQOL was confirmed only for female gender, living conditions, and time spent at a screen. Conclusion: socioeconomic and lifestyle factors affect the quality of life of schoolchildren regardless of the presence of background chronic conditions, which must be taken into account when studying the psychosocial consequences of diseases as important confounding factors. The knowledge gained could be of use for the formation of risk groups in the adolescent cohort.

The aim of the study was to reveal the relationship between the parameters of actual nutrition and the lipid peroxidation and antioxidant defense system in adolescents aged 14–17 in a rural area. Material and methods. 76 adolescents aged 14–17 of the Irkutsk region were examined by the cross-sectional study method. Actual nutrition was studied by the 24-hour nutrition reproduction method. The content of substrates with unsaturated double bonds (DB), diene conjugates (DC), ketodienes and conjugated trienes (KD and CT), thiobarbituric acid reacting species (TBARS), α-tocopherol, retinol, reduced (GSH) and oxidized glutathione (GSSG), total blood antioxidant activity (TAA), superoxide dismutase (SOD) activity in blood by spectrophotometry and fluorometry methods were analyzed. Results. The adolescents’ diet did not meet the principles of a balanced diet – there was reduced protein intake, an imbalance of unsaturated fatty acids, A, C, D, B vitamins deficiency. An excessive element in the diet was sodium. The content of substrates with DB, KD and CT and TBARS increased significantly in the studied group of adolescents, the concentration of DC decreased. Parameters of antioxidant defense both decreased (TAA, retinol content) and increased (α-tocopherol, GSH concentration). Correlation analysis showed relationships between DB and vitamin B1, B2 content; DC level and calories, carbohydrate and vitamin B1 content; concentration of KD and CT and fats, TAA and vitamin A and β-carotene level; level of α-tocopherol in blood and vitamin E in food; GSH and vitamin K; SOD activity and vitamin H content. Multiple negative correlations were between GSSG and fat, vitamins B1, B9, C, K food concentration were found.Conclusions. The calculated vitamin consumption indicators allow to reveal nutritional deviations in adolescents and to connect them with the real provision of the body with these metabolites.
