Background

Respiratory infections are a major cause of morbidity and mortality among older adults.

Purpose

This study aimed to identify factors associated with respiratory vaccination uptake among older adults living in rural Amazonian communities in Peru.

Methods

We conducted an observational, analytical, cross-sectional study using secondary data from the Amazon Frail Project.

n = 429 adults
Results

fewer than half of older adults had gotten the yearly flu shot

Influenza
42.89%
Pneumococcal
23.08%
Pertussis
4.43%
COVID-19
70.16%
More results

Only 3.50% of participants had received all four respiratory vaccines.

Higher educational attainment, multimorbidity, social frailty, greater muscle mass, better physical performance, and healthcare center attendance were associated with higher vaccination uptake.

More results

Depressive symptoms, cognitive impairment, functional dependency, physical frailty, dynapenia, and higher body mass index were associated with lower vaccination uptake.

Conclusion · 1 of 2

Respiratory vaccination coverage was suboptimal among older adults living in rural Amazonian communities.

Conclusion · 2 of 2

Educational, functional, physical, social, and healthcare access factors significantly influenced vaccine uptake, highlighting the need for targeted immunization strategies in vulnerable rural populations.
