ABSTRACT
Objective:
to identify sociodemographic factors, clinical conditions and sarcopenia parameters that predict hospital admission and death in older adults with cognitive impairment.
Method:
this is a longitudinal observational study carried out with 170 older adults with cognitive impairment assessed between 2019 and 2021. Predictor variables were sociodemographic characteristics, clinical conditions and sarcopenia parameters. Sarcopenia was operationalized through handgrip muscle strength (dynamometry), muscle mass (calf circumference) and the Timed Up and Go test. Occurrence of hospital admission and death within one year after assessment of older adults were the predicted variables. Analyzes were carried out using descriptive statistics, independent Student’ t-test, Mann-Whitney U test, chi-square test and univariate logistic regression.
Results:
most participants were female (±77.57 years old), with low education, sedentary, 15.9% with sarcopenia and 13% with a history of hospital admission. It was identified that education level had an effect on occurrence of hospital admission (U=1,423.5, p=0.027) and death (U=647.0, p=0.025) within one-year follow-up. Furthermore, there is an association between history of hospital admission in the last 6 months and occurrence of hospital admission [χ2(1)=4.729; p=0.030] and death [χ2(1)=3.919; p=0.048] within one year follow-up. It was identified that history of hospital admission in the last 6 months was associated with occurrence of hospital admission within one-year follow-up (OR=2.963; 95%CI 1.076-8.165, p=0.036).
Conclusion:
history of hospital admission in the last six months is associated with occurrence of hospital admission over a year in older adults with cognitive impairment.
