Adolescent sleep quality as critical component of healthy lifestyle
(Independent Publisher Zhanneta Kozina : Charkov, 2024) Adamčák, Štefan; Marko, Michal; Bartik, Pavol
Background and purpose: Adolescence is a critical period for physical, emotional, and cognitive development. High-quality sleep during this phase is essential for healthy growth, emotional well-being, optimal weight, and learning. These factors significantly influence the academic achievements of young people. Purpose: to develop and experimentally justify the methodology of training basketball teams of humanitarian higher educational institutions, taking into account the psychophysiological capabilities of the players. Material and methods: The sample consisted of 626 secondary vocational school students aged 17 years from the Central Slovakia region (353 girls and 273 boys). Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). The questionnaires were distributed electronically via Google Forms from October 2023 to March 2024. The results were analyzed with an emphasis on gender differences using the chi-square test (χ2), F-test, and independent t-test at significance levels of p<0.01 and p<0.05, respectively. Results: The majority of students, both boys and girls, fell asleep between 11:00 PM and midnight. The average bedtime was 10:54 PM for girls and 10:50 PM for boys, with no significant differences between genders. Significant differences were found in wake-up times, with nearly 40% of girls waking up before 6:00 AM, compared to only 24% of boys (p<0.01). Boys experienced fewer difficulties falling asleep, with 21% falling asleep within 15 minutes (p<0.05). The average sleep duration was 6 hours and 28 minutes for girls and 6 hours and 55 minutes for boys, a statistically significant difference (p<0.01). Sleep efficiency was higher in boys (84.25%) compared to girls (78.75%). Sleep problems, daytime dysfunction, and mood changes were more frequent among girls (p<0.01). Only 28.33% of girls and 39.19% of boys had good sleep quality (p<0.01), while 17.00% of girls and 4.40% of boys exhibited severe sleep disturbances Conclusions: Our findings indicate significant gender differences in sleep habits and quality, consistent with existing literature. These results highlight the need for increased attention to sleep issues among adolescents and the implementation of preventive and intervention measures to improve sleep quality, which could have a positive impact on their overall health and well-being.
Differences in gender of adolescents’ leisure time satisfaction in Slovakia: Do adolescent boys participate in more physical activity than girls?
(H.S. Skovoroda Kharkiv National Pedagogical University : Charkov, 2025) Adamčák, Štefan; Izáková, Andrea; Marko, Michal; Bartik, Pavol; Hůlka, Karel
Background and purpose: Adolescents’ leisure time satisfaction plays an important role in development (their), influencing academic success, self-esteem, and/or well-being. Structured leisure is associated with higher satisfaction, while unstructured is associated with health problems (mental). Study aims to examine adolescents’ leisure time satisfaction in Slovakia; in particular, differences in gender. Material and methods: 20-item survey was carried out 10 weeks (January 1 – March 10, 2024), targeting 2764 Slovak adolescents (41.98% boys, and 58.02% girls) aged 17.4–17.6 years. 20-item survey, adapted for study, examined the Slovak adolescents’ leisure time satisfaction across 5 sections; in particular, active leisure, passive leisure, education leisure, leisure caring, and social leisure, and by means of Assumption of Homogeneity of Variance and Independent Samples, 2-Sample T-Test, and Anova, of which the significance level (p) was 0.01 and 0.05 (Ibm Spss Modeler). Results: Adolescent boys and girls reported moderate satisfaction in leisure time (boys: 3.44, girls: 3.48); however, significant (p) differences in gender were in specific sections of leisure. Adolescent boys reported higher satisfaction in active leisure (2.80 vs. 2.36; p < 0.01), while girls reported higher satisfaction in passive leisure (3.66 vs. 3.30; p < 0.01), leisure education (2.66 vs. 2.46; p < 0.01), leisure caring (2.56 vs. 2.36; p < 0.01), and social leisure (2.30 vs. 2. 14, p < 0.01). Results (our) indicate that adolescent girls derive (more) satisfaction from leisure that involve learning, nurturing, and social interaction. Conclusions: It (study) highlights significant (p) differences in gender in adolescents’ leisure time satisfaction, as is shaped by social norms and preferences of adolescents. Adolescent boys seek autonomy and competence in active pursuits, while girls prioritize emotional connection and engagement in social leisure and leisure caring. Results (our) emphasize needs of gender-inclusive leisure programs that encourage diverse participation and/or address cultural (social) barriers.

(Trenčianska univerzita Alexandra Dubčeka v Trenčíne, 2024) Adamčák, Štefan; Marko, Michal; Kľocová Adamčáková, Zora; Azor, Stanislav; Bartik, Pavol
Theoretical background. Sleep quality and its importance in high school students is paramount because recognizing the sleep needs of high school students is important because of well-being (health) and academic performance (success); therefore, the aim of study was to examine the sleep quality of high school students in Slovakia. Materials and Methods. Research instrument (Pittsburgh Sleep Quality Index) was carried out 6 months (January - June) because of examining (e.g., analyze, compare) the sleep quality of high school male (630; 45.65 %) and female (750; 54.35 %) students in Slovakia, attending the grammar (598; 43.34 %) and vocational (782; 56.66 %) high schools, and living in Zvolen (720; 52.18 %) and B. Bystrica (660; 47.82 %). Examining the sleep quality of high school students (1 380; 100 %) in Slovakia was by means of chi-square test, of which the significance level was 0.01 and 0.05 and Pearson's r (Ibm Spss Modeler). Results. Significant difference (0.01; 0.05) between high school male (630; 45.65 %) and female (750; 54.35 %) students was in sleep quality (0.01), sleep latency (0.01), sleep duration (0.05), sleep disturbance (0.01), sleep medication (0.01), and daytime dysfunction (0.01). No difference (0.01; 0.05) between high school students (1 380; 100 %) was in sleep efficiency (˃ 0.05). Conclusions. Supporting sleep habits (quality); in particular; consistent bedtimes, promoting and creating sleep environment (safe), improves the sleep quality in high school students. Sustaining communication (open) about sleep issues may facilitate the development of effective sleep strategy tailored to individual needs.
