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

ABSTRACT

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.
