Association between carotene intake and hospital-acquired pneumonia in elderly men: a cross-sectional study.

ABSTRACT:

Background

Elderly inpatients are at high risk for hospital-acquired pneumonia (HAP). The association between dietary carotene and HAP remains unclear.

Methods

This cross-sectional study included 165 patients aged ≥ 80 years. Dietary carotene intake was assessed via 72-hour recall and food weighing, analyzed using the China Food Composition Table. Based on tertiles of dietary carotene intake, patients were stratified into low- (T1, < 713.3 µg/day; n = 55), medium- (T2, 713.4-2101.4 µg/day; n = 54), and high-intake groups (T3, ≥ 2101.6 µg/day; n = 56). Multivariable logistic regression, restricted cubic splines, threshold analysis and subgroup analyses were used to evaluate the relationship between dietary carotene intake and HAP.
