Investigation of the relationships between frailty, nutritional status and muscle strength and the incidence and severity of Covid-19 among the residents of nursing homes. Results from the SENIOR cohort

Few studies have investigated the factors associated with the incidence of Covid-19 in nursing homes. The aim of this study was to investigate the relationships between frailty, nutritional status, muscle strength and the Covid-19 incidence and severity in nursing home residents. Data from the last two years of follow-up of the SENIOR (Sample of Elderly Nursing homes individuals: an Observational Research) cohort were used. A total of 75 participants of the cohort were included, 56 % of whom had Covid-19. After adjustment for covariates, no association was found between frailty, nutritional status or grip strength and the incidence and severity of Covid-19.
