Objective To explore the effects of psychological disorders on qualityoflife of elderly patients with non-erosive reflux disease (NERD) under maintenance treatment of proton pump inhibitors (PPIs). Methods A total of 76 elderly patients with NERD treated by proton pump inhibitors (maintenance treatment of Esomeprazole over half a year) were enrolled. They were classified into symptom group aged (66.5±8.2) years (n=35) and symptom group aged(68.2+6.9)years (n=41)according to reflux symptoms,with 20 healthy people aged(65.4 ±8.8)years as control.The subjects completed the questioniaires on psychological status including self-rating anxiety scale (SAS) and self-rating depression scale (SDS) and their quality of life was evaluated by gastroesophageal heath related quality-of-life instrument(GERD -HRQL) and medical outcomes study short form(SF-36). Results Scores of SAS and SDS were significantly higher in symptom group (54.9±6.2,57.9±8.6) than in symptomless(37.9±8.7,42.7±7.9) and health control group (38.9± 7.2,43.1 ± 8.9),all (P＜0.05),but there was no difference between symptomless and health control group.The rates of anxiety and depression in symptom group (51.4％,57.1％) were increased as compared with symptomless (12.2％,9.8％)and health control group(0.0％,5.0％).Scores of GERD HRQL in symptom group were higher than in symptomlcss group (21.4± 5.0 vs.4.5±2.2,t=19.76,P＜0.01)while the indexes such as body pain,vitality,social function,affection,mental and whole health in score of SF-36 besides physiology function were lower in symptom group than in symptomless and control groups (P＜0.05 or P＜0.01 ).Only the significant differences in mental and whole health of SF-36 were found between symptomless and control groups (P＜0.01).Correlation analysis revealed that SAS and SDS scores were positively correlated with scores of GERD-HRQL in symptom group(P＜0.01) and negatively with all dimensions of SF-36 but physical function (P＜ 0.05). Conclusions Most of elderly symptomatic patients with NERD treated by PPI are in psychological disorders which results in lower quality of life.
