BACKGROUND
Chronic gastritis is accompanied by varying degrees of gastrointestinal symptoms, which affect people's quality of life. The association between dietary behaviors and gastrointestinal symptoms of patients with chronic gastritis has been proved recently. However, no studies have been conducted to investigate the relationship between dietary behaviors, gastrointestinal symptoms, and quality of life.
METHODS
A cross-sectional survey of 176 patients diagnosed with chronic gastritis aged 18 to 65 years, comprising their information on demographic characteristics, dietary behaviors, gastrointestinal symptoms, and quality of life, was collected. A descriptive analysis and a correlation matrix were used to illuminate the characteristics of the subjects and bivariate correlation, respectively. The mediation model was analyzed using the PROCESS macros for SPSS.
RESULTS
Demographic characteristics were found to influence the symptoms, dietary behaviors, and quality of life of chronic gastritis patients; in particular, students categorized by occupation had higher levels of gastrointestinal symptoms and lower levels of quality of life and dietary behavior. The study variables were all pound related. We found that gastrointestinal symptoms played a partial mediating role between dietary behavior and both the physical components summary and mental components summary, and the ratios of mediating effects to the total effect on the physical components summary and mental components summary were 23.5% and 21.5%, respectively.
CONCLUSION
Our survey discovered that dietary behavior, gastrointestinal symptoms, and quality of life were all pairwise related. The effect of dietary behavior on quality of life was partially mediated by gastrointestinal symptoms. These results may provide a novel perspective for medical staff in improving the quality of life of patients with chronic gastritis.
背景
慢性胃炎伴有不同程度的胃肠道症状，影响人们的生活质量。近期已证实饮食行为与慢性胃炎患者胃肠道症状之间存在关联。然而，尚未有研究调查饮食行为、胃肠道症状与生活质量之间的关系。
方法
对176例年龄在18至65岁之间被诊断为慢性胃炎的患者进行横断面调查，收集他们的人口统计学特征、饮食行为、胃肠道症状和生活质量等信息。分别采用描述性分析和相关矩阵来阐明研究对象的特征和双变量相关性。使用SPSS的PROCESS宏分析中介模型。
结果
发现人口统计学特征会影响慢性胃炎患者的症状、饮食行为和生活质量；特别是按职业分类的学生胃肠道症状水平较高，生活质量和饮食行为水平较低。研究变量均显著相关。我们发现胃肠道症状在饮食行为与身体成分总结和心理成分总结之间起部分中介作用，对身体成分总结和心理成分总结的中介效应与总效应的比值分别为23.5%和21.5%。
结论
我们的调查发现饮食行为、胃肠道症状和生活质量两两相关。饮食行为对生活质量的影响部分由胃肠道症状介导。这些结果可能为医务人员改善慢性胃炎患者的生活质量提供新的视角。
