Factors associated with community-acquired pneumonia in older adults attending a geriatric center: a cross-sectional study
Abstract
Introduction: Pneumonia is a major cause of morbidity and mortality in older adults. Objective: To determine the factors associated with a history of community-acquired pneumonia in older adults treated at the Geriatrics Service of the Centro Médico Naval del Perú. Methods: An observational, analytical, cross-sectional study was conducted based on a secondary analysis of a previously established database from the Geriatrics Service of the Centro Médico Naval del Perú. Data from 1,896 outpatients aged 60 years or older were analyzed. Sociodemographic, clinical, and laboratory variables were evaluated. Bivariate analysis was performed using the chi-square test, and multivariable analysis was conducted using Poisson regression with robust variance to estimate adjusted prevalence ratios (aPR) and 95% confidence intervals (95% CI). Results: A total of 1,896 older adults were included, and the prevalence of pneumonia was 15.6%. In the multivariable analysis, a history of chronic kidney disease (aPR: 1.35; 95% CI: 1.08–1.69), polypharmacy (aPR: 1.35; 95% CI: 1.08–1.69), cognitive impairment assessed by MoCA (aPR: 1.62; 95% CI: 1.28–2.06), and a history of cerebrovascular disease (aPR: 1.69; 95% CI: 1.26–2.28) were independently associated with pneumonia. Conclusions: In older adults attending a geriatric center, a history of community-acquired pneumonia was independently associated with chronic kidney disease, polypharmacy, cognitive impairment assessed by MoCA, and a history of…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 1,896 participants or records.
