Relationship between musculoskeletal pain, sleep quality and migraine with level of physical activity in college students during the COVID-19 pandemic

Relationship between Pain, Physical Activity, Screen Time and Age among Young Children during the COVID-19 Pandemic

INTRODUCTION

During the COVID-19 pandemic, many countries implemented restrictions, social distancing measures, and lockdowns to limit the spread of the disease. These lockdowns have affected children's screen time (ST), pain, and physical activity (PA) levels. The present study aimed to explore the relationships between ST, pain, age, and PA before, during, and after the COVID-19 pandemic.

METHODS

The caregivers of 329 children (median age = 8 years) filled out an online self-reported survey about the children's PA, ST, and pain before, during, and after the COVID-19 curfew. Spearman's rank correlation coefficient was used to explore the associations between these variables.

RESULTS

After the curfew, pain that existed before the pandemic had a weak negative relationship with PA intensity (-0.11, p = 0.04) and a weak positive relationship with ST (r = +0.12, p = 0.04). There was a strong positive relationship between ST in all time periods (p > 0.01). PA and ST had a weak negative relationship (p > 0.05) during the curfew and after the curfew but not before the COVID-19 pandemic. Age had a weak positive correlation with ST in all time periods (p > 0.01). In addition, ST was affected by the curfew.

CONCLUSION

The study findings indicated that young children had longer ST during the curfew and after the curfew compared with before the curfew. Increasing PA could lessen children's ST, which could, in turn, increase the probability that their general pain would decrease.

Analysis of musculoskeletal pains and productivity impacts among hispanic construction workers

This study investigated the top three musculoskeletal pains (MSP) among Hispanic construction workers in Texas and the relationship between sleep hours, age, and MSPs on worker productivity. The study recruited 228 participants from 28 small construction companies and surveyed them on their occupation, age, sleep hours, MSP, and the impact of pain on productivity. The results indicated that Foot pain was the most common among these workers, followed by Back pain and others. Additionally, the study found that the Foot was the most common body part reported with MSP among roofers, drywall installers, laborers, and helpers. The study conducted a three-factor ANOVA test to analyze if there were any significant differences in productivity based on age, number of MSPs, and sleep hours. The study found that MSPs and sleep hours significantly impacted productivity. However, there was no significant effect of age. The results also showed that the number of MSPs significantly impacted productivity, with an increase in MSPs leading to a more severe impact on productivity. Additionally, those who slept less than 6 h per day had a more severe impact on productivity than those who slept more. The study suggests that targeted interventions to improve musculoskeletal health and productivity in this population are needed and highlights the importance of considering Hispanic construction workers' specific needs when implementing safety measures and addressing pain management in the workplace.

Ergonomics of E-Learning Workstations and the Prevalence of Musculoskeletal Disorders-Study among University Students

The prevalence of musculoskeletal disorders (MSD) has increased significantly in recent years. The COVID-19 pandemic has led to a fundamental change in the lifestyles, ways of learning and working patterns of the general population, which in turn, might lead to health consequences. The aim of this study was to evaluate the conditions of e-learning and the impact of the learning modality on the occurrence of musculoskeletal symptoms among university students in Poland. This cross-sectional study included 914 students who completed an anonymous questionnaire. The questions covered two time periods (before and during the COVID-19 pandemic) and were aimed at obtaining information about lifestyle (including physical activity using the modified International Physical Activity Questionnaire, 2007 (IPAQ), perceived stress and sleep patterns), the ergonomics of computer workstations (by Rapid Office Strain Assessment, 2012 (ROSA) method), the incidence and severity of musculoskeletal symptoms (by the Nordic Musculoskeletal Questionnaire, 2018 (NMQ)) and headaches. The main differences between the two periods were statistically significant according to the Wilcoxon test in terms of physical activity, computer use time, and severity of headaches. During the COVID-19 pandemic, there was a significant increase in MSD (68.2% vs. 74.6%) and their intensity (2.83 ± 2.36 vs. 3.50 ± 2.79 points) among the student population (p < 0.001). In the group of students with MSD, there was a high musculoskeletal load, due to the lack of ergonomic remote learning workstations. In future, a thorough study should be carried out, and there is an urgent need to raise students' awareness of arranging learning workstations according to ergonomic principles in order to prevent the occurrence of musculoskeletal problems.

Research on the relationship between physical activity, sleep quality, psychological resilience, and social adaptation among Chinese college students: A cross-sectional study

Background

Sleep quality has become a frequent and prominent public health problem in Chinese universities, which seriously hinders the healthy development of college students and the improvement of the quality of higher education.

Objective

The purpose of this study is to explore the relationship between physical activity and sleep quality among Chinese college students, and the mechanism of psychological resilience and social adaptation, and provide suggestions for improving the sleep quality among Chinese college students.

Methods

From August to September 2022, a cross-sectional survey was conducted by using the convenience sampling method in Guangdong Province. 1,622 college students were investigated with Physical Activity Scale, Pittsburgh Sleep Quality Index Scale (PSQI), Psychological Resilience Scale, and Social Adaptation Diagnostic Scale, of which 893 were male and 729 were female. Use SPSS 23.0 and PROCESS plug-ins to analyze data.

Results

(1) There was a significant negative correlation between physical activity and sleep quality (r = -0.237), and the direct path of physical activity to sleep quality was significant (β = -0.236, t = -9.888, p < 0.01); (2) physical activity can positively predict psychological resilience (β = 0.215, t = 8.823, p < 0.01) and social adaptation (β = 0.164, t = 7.773, p < 0.01); psychological resilience can negatively predict sleep quality (β = -0.337, t = -15.711, p < 0.01), positive prediction of social adaptation (β = 0.504, t = 23.961, p < 0.01); social adaptation can negatively predict sleep quality (β = -0.405, t = -18.558, p < 0.01); (3) psychological resilience and social adaptation play a significant mediating role between physical activity and sleep quality. The mediation effect consists of three paths: physical activity → psychological resilience → sleep quality (mediation effect value is -0.0723), physical activity → social adaptation → sleep quality (mediation effect value is -0.0662), and physical activity → psychological resilience → social adaptation → sleep quality (mediation effect value is -0.0438). (4) There is no gender difference in chain mediated effect.

Conclusion

(1) Physical activity can significantly positively predict college students' psychological resilience and social adaptation, and negatively predict sleep quality, which means that physical activity may help improve college students' psychological resilience and social adaptation, and reduce sleep quality problems; (2) physical activity can not only directly affect the quality of sleep, but also indirectly affect the quality of sleep through the independent intermediary role of psychological resilience and social adaptation and the chain intermediary role of both. This further explains the reason why physical activity plays a role in college students' sleep quality, which will help to provide some inspiration for colleges and universities to reduce college students' sleep quality problems and formulate intervention plans.
