Abstract

BACKGROUND
Korean Americans constitute the fifth largest subgroup in the Asian American population. Despite their increasing population, research and guidelines regarding their health status assessment and disease screening are lacking. This study aimed to compare the prevalence of diseases in Korean Americans and native Koreans to determine the risk factors and guidelines for disease screening.
METHODS
Patients who visited the Gangnam Severance Hospital from February 2010 to May 2015 for a health checkup were enrolled in this study. Baseline characteristics, laboratory data, and the organs (stomach, colon, thyroid, brain, prostate, lung, liver, kidney, pancreas, adrenal gland, and heart) of patients were examined. Data regarding patients' dietary patterns were also obtained. Overall, 1,514 Korean Americans (group 1) and 1,514 native Koreans (group 2) were enrolled.
RESULTS
The following diseases were more prevalent in group 1 than in group 2: reflux esophagitis (12.9% vs. 10%), gastric ulcer (3.0% vs. 5.5%), colorectal polyp (37.7% vs. 28.7%), hemorrhoids (32.2% vs. 29.9%), and benign prostatic hyperplasia (30.2% vs. 14.3%). Although not statistically significant, coronary artery disease has a high prevalence rate of >20% in both groups. Dietary patterns were not significant between the two groups.
CONCLUSION
This study showed that the prevalence of several diseases in Korean Americans differed from that observed in native Koreans. Therefore, a foundation for setting up new guidelines for disease screening among Korean Americans is established.
