Abstract

Purpose: This study investigated the effects of body mass index (BMI), waist circumference (WC), and depressionon asthma in older adults Koreans.

Methods: Data for 1,388 individuals (¡Ã65 years) were extracted from the KoreaNational Health and Nutrition Examination Survey (KNHANES ¥·-2, 2020). Complex sampling design data wereanalyzed using stratification, clustering, and weights. Data were analyzed using unweighted frequencies,weighted percentages, estimated means and standard errors, the Rao-Scott x2 test, and multiple logisticregression analysis, which was performed to identify variables that influenced asthma after adjusting forconfounding factors.

Results: The factors influencing asthma in the older adults were a depression diagnosis, ageat the onset of depression, current depression status, and gender. In contrast, BMI and WC did not affect asthma.
A diagnosis of depression had an odds ratio of 3.07 for asthma in the older adults. Furthermore, the odds ratiosfor asthma in the older adults were 5.08 for depression onset at <49 years and 3.37 for current depressioncompared to no depression diagnosis. The odds ratio for asthma in female older adults was 1.35.

Conclusion:The results of this study suggest that asthma in the older adults could be detected early through depressionsymptoms. This study also provides evidence that depression-related interventions should be included in asthmaprevention and management programs for the older adults in Korea.
