Abstract

Objectives

This study aimed to investigate the relationship between lifestyle and gallstones.

Materials and Methods

We performed an observational study using the 2018–2020 National Health and Nutrition Examination Survey (NHANES). Univariate and multivariate-adjusted logistic regression analyses were performed to assess the correlations between lifestyle factors and gallstone risk. Second, Mendelian randomization (MR) was applied to decrease the causal relationship between lifestyle factors and gallstones.

Results

This observational study enrolled 11,970 individuals. The risk of gallstones was found to increase with increased sitting time (odds ratio (OR) 1.03, 95% CI 1.00–1.05, p = 0.02). In contrast, the risk of gallstones was found to decrease with recreational activity (OR 0.50, 95% CI 0.29–0.87, p = 0.02). The results of the MR also showed that time spent watching television (OR 1.646; 95% CI 1.161–2.333, p = 0.005) and physical activity (OR 0.953, 95% CI 0.924–0.988, p = 0.003) remained independently causally associated with gallstones.

Conclusions

Prolonged sitting increases the risk of gallstones, whereas recreational activity reduces the risk. These findings need to be verified in further prospective cohort studies with larger sample sizes and longer follow-up periods.
