Objective To systematically evaluate the related factors of constipation in patients with stroke. Methods Cochrane Library, PubMed, Web of Science, Embase, CNKI, VIP, Wanfang and China Biomedical Literature Database were searched by computer, and the retrieval time was set to May 2022. Case-control studies, cohort studies and cross-sectional studies on stroke and constipation were selected. Meta-analysis was performed using RevMan 5.3 software. Results A total of 13 studies involving 2 834 patients were included. Meta-analysis showed that age [odds ratio (OR) =2.54, 95% confidence interval (CI) (1.36, 3.73), P<0.001], lesion location [OR=1.98, 95%CI (1.27, 3.11), P=0.003], National Institutes of HealthStroke Scale score [OR=0.40, 95%CI (0.10, 0.70), P=0.010], hemiplegia [OR=4.31, 95%CI (2.59, 7.17), P<0.001], dysphagia [OR=2.32, 95%CI (1.27, 4.25), P=0.006], antidepressants [OR=2.33, 95%CI (1.62, 3.34), P<0.001], BI score [OR=−17.08, 95%CI (−33.07, −1.08), P=0.04], eating pattern [OR=4.18, 95%CI (1.16, 15.09), P=0.030], drinking water volume ≥800 mL [OR=0.30, 95%CI (0.19, 0.46), P<0.001] might be the influencing factors of constipation in patients after stroke. The results of sensitivity analysis showed that age, education level, diabetes, smoking, stroke type, lesion location, diuretic and BI score might be the influencing factors of constipation after stroke (P<0.05). The results of bias analysis suggest that publication bias is less likely. Conclusions  There are many risk factors for constipation in patients with stroke. Current evidence shows that age, diabetes, smoking and other 11 factors may be risk factors for stroke constipation, while high education level and drinking water ≥800 mL may be protective factors, and the other influencing factors have not been determined and need further study.
