Patterns and correlates of sedentary behavior among university students

Sedentary behavior is associated with the mental health of university students during the Covid-19 pandemic, and not practicing physical activity accentuates its adverse effects: cross-sectional study

BACKGROUND

Movement behaviours, such as sedentary behavior (SB) and physical inactivity, have become a public health issue due to their implications for physical and mental health. The literature indicates that the university environment influences the movement behaviors of university students, and the strategies adopted during the pandemic may have favored a decrease in the practice of physical activity and an increase in the time dedicated to SB in this population. We aimed to evaluate the association of SB and moderate to vigorous leisure-time physical activity (MVPA) with presence of symptoms of mental disorders during the COVID-19 pandemic.

METHODS

This is a multicenter survey conducted with undergraduate students from eight Brazilian universities between October 2021 and February 2022 using an online questionnaire. The outcome variable was symptoms of anxiety and depression, assessed by the Depression, Anxiety, and Stress Scale-21. SB was assessed by total sitting time, being that individuals with ≥ 9 h/day were classified with high SB. The practice of MVPA was evaluated based on weekly frequency, duration, and type of exercise. Subsequently, the ratio between the time spent in MVPA (minutes/day) and the time spent in SB (hours/day) was calculated, being considered as cutoff point was the practice of 2.5 min of MVPA for each sedentary hour. To assess the association between the outcome and explanatory variables, multivariable logistic regression was performed.

RESULTS

A total of 8,650 students participated in the study, with an average age of 23.9 years (SD: ± 6.34). In the multivariate analysis, the odds of anxiety symptoms [OR: 1.37 (95% CI: 1.24-1.50)] and depression [OR: 1.61 (95% CI: 1.47-1.77)] were higher in individuals with ≥ 9 h of SB per day. In the analysis of the relationship between MVPA and SB, not engaging in 2.5 min of MVPA per hour of SB increases the odds of anxiety symptoms [OR: 1.44 (95% CI: 1.31-1.58)] and depression [OR: 1.74 (95% CI: 1.59-1.92)].

CONCLUSION

The results suggest that SB is a risk factor associated with symptoms of anxiety and depression and that not engaging in MVPA exacerbates the negative effects of SB.

Effects of Physical Activity and COVID-19 on Healthy Student Strengths in the University System: Implications for Post-Pandemic Management

The COVID-19 pandemic has profoundly affected the physical, mental, and social well-being of millions worldwide. It has also brought about abrupt disruptions to the entire university system, whose students form a crucial segment of society. The pandemic's effects on student education and well-being have been particularly significant. One of the primary consequences has been a drastic reduction in physical activity levels among students, leading to mental and physical health problems. Despite the rapid growth in the literature exploring student experiences during the pandemic, there is a paucity of research on how this decline in physical activity has affected the five strengths of the healthy student: optimism, self-efficacy, resilience, engagement, and hope. Therefore, the aim of this investigation is to examine the relationship between physical activity levels and the five strengths of the healthy student at two different time points (pre-COVID-19 and COVID-19) through the International Physical Activity Questionnaire (IPAQ) and the Healthy Student Questionnaire. The study involved 897 participants, with 290 participating in the pre-COVID-19 phase and 607 participating in the COVID-19 phase. The results revealed significant differences in the five strengths between the two periods. Students who engaged in physical activity exhibited significantly higher optimism scores in the pre-COVID-19 phase. During the COVID-19 phase, physically active students demonstrated significantly higher scores in optimism, resilience, and self-efficacy. These findings provide clear guidance for university administrators seeking to enhance student well-being in a post-pandemic world and in the face of future disruptions. Universities should consider implementing physical exercise programs for their students to promote psychosocial well-being and provide training and resources to equip faculty members with new skills to better understand and support students' perceptions.

The Relationship between Physical Activity and Life Satisfaction among University Students in China: The Mediating Role of Self-Efficacy and Resilience

(1) Background: Universities play a crucial role in nurturing healthy habits, and physical activity has emerged as a valuable tool for enhancing the life satisfaction, self-efficacy, and resilience of college students. Therefore, the purpose of this study was to investigate the mediating role of physical activity in the relationship between life satisfaction and self-efficacy as well as resilience among Chinese university students. (2) Method: This study used the Physical Activity Rating Scale (PARS-3), the Self-Efficacy Scale (CGES), the Mental Toughness Scale (CD-RISC), and the Life Satisfaction Scale (CSLSS) to administer questionnaires to 353 university students from two universities in Chengdu, Sichuan Province. Using a random simple sampling method, the data were processed and analyzed using SPSS 22.0 and Excel software. (3) Results: (1) Physical activity exhibited a significant positive correlation with self-efficacy, resilience, and life satisfaction; self-efficacy was significantly and positively related to resilience and life satisfaction; and resilience was significantly and positively related to life satisfaction. (2) Physical activity had a positive predictive effect on life satisfaction (β = 0.2771; 95% confidence interval (CI): 0.1905, 0.3637, 55.51%). (3) Self-efficacy (β = 0.0368; 95% confidence interval (CI): 0.0087, 0.0692, 7.37%) and resilience (β = 0.137; 95% confidence interval (CI): 0.0919, 0.1894, 27.44%) mediated the relationship between physical activity and life satisfaction. Also, the chain-mediating effect of self-efficacy and resilience between physical activity and life satisfaction reached significant levels (β = 0.0483; 95% confidence interval (CI): 0.0279, 0.0745, 9.68%). (4) Conclusion: Active participation in physical activity not only enhanced the life satisfaction of college students but also indirectly impacted their life satisfaction by improving their self-efficacy and resilience. Consequently, this led to an overall improvement in the life satisfaction of college students.
