Objective: To perform Meta-analysis to identify risk factors associated with gallbladder polyps (GBP) formation in east Asian population. Methods: Three English electronic bibliographic databases includes PubMed, Embase and Medline, with reviewed researches from 1986 to 2017. All possible risk factors of GBP formation were recorded. Meta-analyses were performed by Review Manager Software. Pooled odds ratios (OR) or the mean difference (MD) were used to determine risk factors. Results: Sixteen studies and 227021 people were recruited, including 17261 people with GBP and 209760 without GBP. For categorical variables evaluated by OR test., risk factors of GBP formation were male gender (OR, 1.63; 95%CI, 1.42–1.87) and positive HBsAg. GBP formation were not correlated with age <50 years old, hypertension, DM, BMI ≥ 25kg/m 2 , smoking, drinking, HDL decrease, TC increase, TG increase, fatty liver and GBS. For continuous variables evaluated by MD test, risk factors of GBP formation were DBP (MD, 1.08; 95%CI, 0.15–2.02), mean BMI (MD,0.19; 95%CI,0.02–0.35), waist circumference (MD,1.780; 95%CI, 0.17,3.40), mean LDL (MD,0.89; 95%CI,0.03–1.75), mean HDL (MD,–1.87; 95%CI,–3.21 to ?0.52). GBP formation were not correlated with mean age, SBP, mean TC, mean TG, ASL and ALT. Conclusion: In conclusion, risk factors of gallbladder polyp formation included male gender, higher BMI, higher waist circumference, higher DBP, higher LDL, lower HDL and positive HBsAg in east Asian population. GBP formation was not correlated with age, hypertension, DM, smoking, drinking, fatty liver, GBS, TC, TG, SBP, ASL and ALT. The mechanism of Dyslipidemias causing GBP needs deeper study in future. ? 2019
