RESUMO
Background: The COVID-19 pandemic has disrupted human well-being worldwide in unforeseen ways. In early 2020, the spread of the virus left its mark on every affected country, impacting mental health by limiting daily activities and causing fatalities amidst public health strategies to mitigate its impact. The influence of COVID-19 on the quality of life (QoL) may vary between countries, underscoring the need to examine its effects on individuals and families during the mandatory home quarantine. We aimed to assess the QoL of individuals and families during home isolation by COVID-19 lockdown. Methods: A cross-sectional study was conducted from February to May 2020. We included adult partners (≥18 years) of families from Brazil, Colombia, Spain, Japan, Peru, Russia, and Venezuela. Using the 26-item World Health Organization Quality of Life Brief (WHOQOL-BREF) questionnaire we assess the impact of COVID-19 on their partner/family member's QoL. Results: The survey was completed by 466 participants (mean age = 38.59 ± 13.75 years; females = 298) and 76% worked mostly as health professionals from South America (69.2%), Europe (18.4%), and Asia (12.4%). The WHOQOL-BREF mean score from 38.38 ± 11.55 (range = 22.8-43.4). The average quality of life in South America (41.9 ± 1.2) was significantly higher than that of European countries (30.9 ± 11.5) (p = 0.002). The social relations dimension was the only one with values close to 100 (mean = 83.3) in 6/7 evaluated countries, where only Spain had a low score (41 ± 33.12). Women had a slightly lower quality of life than men, but it was not significant (40.2 ± 8.8 vs. 41.5 ± 9.9, p = 0.354), while we found differences in the overall QoL between young and older, and by employment type (p < 0.05). According to family structure, we found differences on QoL between nuclear and siblings' families (p = 0.024). Conclusion: Families from seven countries of three continents reported poor QoL during the first outbreak of COVID-19. The pandemic scenario has dramatically weakened the QoL in 3/4 dimensions, where social relationships have remained high. It is important to fully address the impact of this reduced QoL on families after several waves of infection and to provide comprehensive support in the post-COVID future.
