Calidad de vida en personas según tipo de confinamiento de estudiantes universitarios chilenos en pandemia por COVID-19 / Quality of life according to type of confinement of Chilean university students during COVID-19 pandemic

BACKGROUND: COVID-19 confinement measures in the population affected the quality of life and sleep. AIMS: To determine if confinement is associated with a lower quality of life and sleep. SUBJECTS AND METHODS: A self-reported survey including questions about type of confinement, time spent in front of a screen, the international physical activity questionnaire (IPAQ), the Sleep Self Report questionnaire and the SF-36 quality of life survey, was answered by 621 Chilean university students. RESULTS: Confined and not confined respondents spent a great amount of time in front of a screen, in sedentary activities and sleeping > 8 or < 6 hours per day. Those who were in confinement reported having a poorer quality of sleep and quality of life compared to those who were not in confinement. Those who required mandatory confinement for suspected COVID-19 had the worst quality of sleep and quality of life. CONCLUSIONS: University students had sedentary lifestyles regardless of the type of confinement. Those who were in confinement, especially for suspected COVID-19 infection, had the worst quality of sleep and quality of life.

Factores asociados a la disminución de funcionalidad del miembro superior en estudiantes universitarios chilenos en pandemia por COVID-19 / Risk factors associated with a lower upper limb functionality among university students

Background: Upper limb (UL) function is compromised in university students due to prolonged academic activities and excessive use of electronic devices. However, it is unknown whether this relationship was affected by the COVID-19 pandemic situation. Aim: To determine the risk factors associated with reduced UL functionality in university students in a pandemic situation due to COVID-19. Material and Methods: Cross-sectional study that included 621 university students from the northern, central and southern areas of Chile. Physical variables, musculoskeletal, anthropometric and sociodemographic history were evaluated through self-reported questionnaires. Results: The factors with the higher association with a lower UL functionality were pain (Odds ratio (OR) = 17.6; 95% confidence intervals (CI) = 5.2-60; p < 0.01) and injury (OR = 10.4; 95% CI = 3.9-28.3; p < .001). Also, a low weight (OR = 10.5; 95% CI = 2.2-49.6; p < 0.01) and a quarantine lasting for five or more weeks (OR = 9.1; 95% CI = 1,1-77.2; p = 0.043) were considered risk factors. The lower probability was observed in male participants (OR = 0.2; 95% CI = 0.1-0.51; p < 0.01) and in those with a moderate/high muscular condition (OR = 0.3; 95% CI = 0.1-0.9; p = 0.031. Conclusions: The identification of these modifiable risk factors can help to implement preventive or rehabilitative actions at home or universities.
