    Background: The pathogenesis of asthma involves both airway inflammation and an oxidant/antioxidant imbalance. It is demonstrated in asthmatic adults that exercise programmes improve lung function, a mechanism yet to be elucidated. The purpose of this study was to investigate the possible beneficial effects of physical exercise on antioxidant status in asthmatic children which may lead to ameliorated lung function. Methods: The study enrolled thirteen control and thirty asthmatic children. The asthmatic group was subdivided into two: the first group receiving only pharmacological treatment (n = 15) and the second receiving pharmacological treatment with exercise programme (n = 15) for 8 weeks. Blood samples were drawn from the subjects before and after treatment periods. As oxidant stress markers blood levels of malondialdehyde (MDA) and total nitric oxide (NO), and as antioxidant status, glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) enzyme activities were assessed. Results: Before any treatment was initiated, MDA and NO levels in the asthmatic group were significantly higher than the controls (3.40 ± 0.96 nmol/ml vs 2.46 ± 0.58 nmol/ml, and 12.53 ± 2.10 vs 9.40 ± 1.39 micromol/L, respectively). Both SOD (p = 0.0001) and GSH-Px (p = 0.023) activities were significantly lower in the asthmatic group. Pharmacological treatment and exercise programme together significantly improved lung performance and decreased the levels of oxidant stress markers, in concordance with a significantly increase in antioxidant enzyme activity measures when compared to the pharmacological treatment. Conclusion: Structured exercise programme in asthmatic children resulted in better lung function, which may be attributed to its effect on antioxidant status. © 2010 SEICAP.

    Non-pharmaceutical interventions (NPIs) implemented to mitigate the COVID-19 pandemic halted everyday life in higher education along with social and psychological impacts. The objective of our study was to explore the factors related to sense of coherence (SoC) from a gender perspective among university students in Turkey. This is a cross-sectional survey conducted online with a convenience sampling method as part of the international COVID-Health Literacy (COVID-HL) Consortium. SoC was measured by a nine-item questionnaire that was adapted to the Turkish language, including socio-demographic information and health status, including psychological well-being, psychosomatic complaints, and future anxiety (FA). 1595 students from four universities, of whom 72% were female, participated in the study. Cronbach's alpha for the SoC scale was 0.75. Based on the median split of the individual scores, levels of SoC showed no statistically significant difference according to gender. Logistic regression analysis indicated that higher SoC was associated with medium and high subjective social status, studying in private universities, high psychological well-being, low FA, and none/one psychosomatic complaint. While results were similar among female students, type of university and psychological well-being showed no statistically significant association with SoC among males. Our results indicate that structural (subjective social status) and contextual (type of university) factors, along with gender-based variations, are associated with SoC among university students in Turkey. © 2023 The Author(s).
