Brief Summary

This is a cross-sectional study aimed to investigate the current status of gastrointestinal health among full-time undergraduate students aged 18-25 years in Dalian, and to clarify the influences of factors such as diet, sleep, psychological mood, and antibiotic use on gastrointestinal symptoms, as well as gender differences. The study plans to enroll 1020 eligible college students and collect information including demographics, gastrointestinal symptoms in the past month, lifestyle, and medication use. Statistical analyses will be performed using the chi-square test, Mann-Whitney U test, Spearman correlation analysis, and multivariate logistic regression. The primary objective is to assess the prevalence and distribution characteristics of gastrointestinal discomfort among college students; the secondary objectives are to identify independent risk factors and analyze gender differences. The results of this study will provide data support for colleges and universities to carry out gastrointestinal health education, schedule and dietary interventions, and rational medication guidance, as well as evidence-based basis for improving digestive health in young populations.
