Gallstone Is Associated with Metabolic Factors and Exercise in Korea.

ABSTRACT

Gallstone is a common health problem. Cholesterol stone accounts for 90% of stones in the United States and Europe, but East Asia has a high proportion of pigment stone. The aim of this study was to determine the relationship between modifiable metabolic factors and gallstone in a region with a high prevalence of pigment stone. Among 3159 participants who underwent health screening at Ulsan University Hospital from March 2014 to June 2019, 178 patients were diagnosed with gallstone using abdominal ultrasonography; 2860 participants were selected as a control group. Demographic and laboratory data, and a medical questionnaire were obtained. Hypertension and diabetes mellitus were more prevalent in the gallstone group. Age, waist circumference, systolic blood pressure (SBP) ≥ 140 mmHg, fasting blood glucose, HbA1c ≥ 6.5%, visceral fat index, normal-attenuated muscle area index, and engaging in vigorous exercise for ≥2 days per week were associated with gallstone by univariate analysis. Through multivariate logistic regression analysis, HbA1c ≥ 6.5% (odds ratio (OR) 1.98, 95% confidence interval (CI) 1.31-2.98), and 2 or more days of vigorous exercise per week (OR 0.66, 95% CI 0.45-0.95) remained significant. The association persisted after adjusted analysis for age and sex. HbA1c ≥ 6.5% were positively associated with the gallstone. Vigorous exercise for at least 2 days weekly may be related to a lower risk of gallstone formation.
