Respiratory allergies in the elderly: findings from the Korean Longitudinal Study on Health and Aging phase I study (2005-2006).

Abstract

Population aging is a global issue, but is estimated to be more rapid and dramatic in Asian countries. In the past, allergy might have been a minor concern in the elderly (usually defined as ≥65 years). However, recent series of epidemiologic studies indicate that allergic diseases are more prevalent than expected in the aged population. Furthermore, they pose significant impact on quality of life and socioeconomic costs. The burden may also increase in the elderly, due to frequent comorbidities and treatment-related complications. The Korean Longitudinal Study on Health and Aging (KLoSHA) cohort study is one of major research projects on the epidemiology of common geriatric disease conditions in Korea. In this review, we summarized the baseline findings on the prevalence, risk factors, comorbidities and impact of geriatric respiratory allergic conditions in the phase I KLoSHA cohort study.
