Prevalence and influencing factors of gallstone disease among rural adult residents: a cross-sectional survey in Xinxiang county, Henan province

  Objective  To examine the prevalence and influencing factors of gallstone disease among rural adults in a county of Henan province.

  Methods  We recruited 9 511 permanent rural residents aged ≥ 18 years from 17 villages in two townships of Xinxiang county, Henan province using multi-stage random cluster sampling. Face-to-face interview, physical examination, laboratory tests, and abdominal ultrasound detection were conducted among the residents during April – June 2017.

  Results  Among the 9 461 participants completing the survey, totally 299 gallstone disease cases were identified, with a prevalence rate of 3.16% and a standardized prevalence rate of 2.28%. The results of the multivariate unconditional logistic regression showed that the participants aged ≥ 45 years, with central obesity or fatty liver were more likely to have gallstone disease; while, drinking alcohol at least 12 times a year or more was a protective factor against the disease.

  Conclusion  The prevalence rate of gallstone disease was relatively low and mainly influenced by age, central obesity, fatty liver, and alcohol consumption among adult rural residents in a county of Henan province.
