Abstract
BACKGROUND: The implementation of social distancing measures during covid-19 influenced health outcomes and population´s behaviors, and its rigidity was very different across countries. We aimed to verify the association between the rigidity of social distancing measures of covid-19 first wave with depression symptoms, quality of life and sleep quality in older adults. METHODS: This is a cross-sectional study including 1023 older adults (90% women; 67.68 ± 5.92 years old) of a community-based program in Fortaleza (Brazil). Dependent variables (depression symptoms, sleep quality, and quality of life) were measured through phone calls along June 2020, during the first covid-19 wave. Confinement rigidity (non-rigorous and rigorous) was considered as independent variable. Sociodemographic characteristics (sex, marital status, scholarity, and ethnicity), number of health conditions, nutritional status, movement behavior (physical activity and sitting time), technological skills, and pet ownership were considered as confounding variables. A binomial logistic regression (odds ratio [OR]) was performed to verify the association of confinement rigidity and depression symptoms, sleep quality, and quality of life, adjusted by confounding variables. RESULTS: Older adults who adopted a less rigid lockdown had a higher frequency of depression symptoms, worse perception of quality of life, and bad sleep quality (p < 0.001). Confinement rigidity was able to explain the probability of depression symptoms occurrence (OR: 2.067 [95% CI: 1.531-2.791]; p < 0.001), worse quality of life (OR: 1.488 [95% CI: 1.139-1.944]; p < 0.05), and bad sleep quality (OR: 1.839 [95% CI: 1.412-2.395]; p < 0.001). Even adjusted by confounding variables, confinement rigidity was able to explain the poor outcomes analyzed in older adults. CONCLUSION: Our findings showed that less rigid lockdown was associated with a superior frequency of depression symptoms, worse sleep quality, and lower perception of quality of life in older adults. Therefore, our study could improve comprehension regarding the impact of social distancing measures rigidity in health-related conditions and in the context of covid-19 and other similar pandemic situations.
