Long COVID Symptoms vs. Back Pain and Physical Activity among Students in Poland—Cross-Sectional Study

Abstract

Background: Back pain (BP) is a common condition that affects people of all ages. Moderate- and vigorous-intensity physical activity (PA) is a key element in maintaining health. The purpose of this research was to determine the level of physical activity and back pain (BP) in students with long COVID symptoms and to determine the relationship between the level of PA and BP in students with and without long COVID. Methods: A survey was carried out among 402 students from Poland. The inclusion criteria were as follows: student status, age of over 18 years, history of COVID-19, and consent to participate in the study. The International Physical Activity Questionnaire (IPAQ) was used to determine the level of PA. The Oswestry Disability Index (ODI) and the Neck Disability Index (NDI) were used to assess BP. Results: We found that at least half of the students surveyed did not experience any lumbosacral or cervical spine pain. The authors found no association between the level of PA in women and a history of long COVID symptoms, while there were statistically significant differences in intense PA in men (p = 0.0263), with those who did not report long COVID symptoms being more active. With regard to cervical and lumbar spine pain complaints, in our study, these were statistically significantly stronger in students who were observed to have long COVID symptoms. The difference was not significant only for lumbosacral complaints among men. No strong correlations were found between PA level and the severity of BP. Conclusion: Additional investigation is required to comprehend the complex interaction between long COVID symptoms and levels of PA and BP. Special attention should be paid to the prevention of back pain mainly in the COVID-19 group of students.
