Investigation of the status quo of emotional disorder in patients with gastrointestinal polyps and its mediating effect on dietary behavior and quality of life

Objective To investigate the status quo of dietary behavior, emotional disorder and quality of life in patients with gastrointestinal polyps, and analyze the mediating effect of dietary behavior on emotional disorders and quality of life.

Methods One hundred and ninety-nine patients with gastrointestinal polyposis were evaluated using the Huaxi Heart Index Scale(HEI), Dutch Eating Behavior Questionnaire(DEBQ) and Spitzer Quality of Life Index(SQLI).The correlation among emotional disorder, dietary behavior and quality of life were analyzed by Pearson, and the structural equation model(SEM) was established by Amos software to test the mediating effect.

Results The scores of quality of life, emotional disorder and dietary behavior in patients with gastrointestinal polyps were (6.57±0.62)(8.42±1.02) and (87.67±9.46), respectively.There was a negative correlation between the quality of life and emotional disorders(P < 0.01), a negative correlation between the quality of life and dietary behaviors(P < 0.01), and a positive correlation between emotional disorders and dietary behaviors in patients with gastrointestinal polyps(P < 0.05 to P < 0.01).The dietary behavior had a mediating effect of 23.19% between emotional disorders and quality of life.

Conclusions Dietary behavior has a mediating effect between emotional disorder and quality of life, which proves that emotional disorder can influence the quality of life of patients by regulating dietary behavior.
