RESUMO
Objective To explore the eating behaviors associated with refractory functional dyspepsia (RFD).Methods In this multicenter,prospective trial,1341 new outpatients with functional dyspepsia (FD) from three Guangdong hospitals who had been diagnosed according to the Rome Ⅲ criteria were enrolled from May to September in 2012.One hundred healthy volunteers were also enrolled as controls.A questionnaire was used to obtain data,and logistic regression analysis was used for analysis.Results ①RFD was diagnosed in 24.4％ of the FD patients.②Unhealthy eating behaviors were significantly greater in patients with RFD and non-RFD than in the normal controls.Patients with RFD skipped meals more often,ate extra meals,and preferred sweets and gasproducing foods (P ＜ 0.05).③A comparison among the non-RFD subtypes,showed that those with epigastric pain syndrome had a greater preference for spicy foods (47.5 ％ vs 35.7 ％,P ＜ 0.05),and those with postprandial distress syndrome had a greater preference for sweets(50.0％ vs 36.4％,P ＜ 0.05) and gas-producing foods (14.9％ vs 7.1％,P＜0.05).Those with both subtypes skipped more meals (30.1％ vs 17.0％,P ＜ 0.05),and ate extra meals (15.0％ vs 6.5％,P＜0.05).④Logistic regression analysis showed that meal skipping(95％ CI,1.177 ～2.272; P=0.003),eating extra meals (95％ CI,1.015 ～2.604; P =0.043),and a preference for sweets (95 ％ CI,1.040 ～ 1.757 ; P =0.024) and gas-producing foods (95 ％ CI,1.022 ～ 2.306 ; P =0.039) were risk factors for RFD.Conclusion Unhealthy eating behaviors,especially,meal skipping,eating extra meals,preferring sweets and gas-producing foods correlate with RFD and these behaviors may be the key reasons for the refractory characteristic of RFD.
RESUMO
Objective To investigate clinical characteristics,quality of life,and psychological factors in functional dyspepsia (FD) patients with weight loss.Methods A multi-center and prospective investigation was conducted (Clinical trial registration number:ChiCTR-TRC-12001968) which recruited 1341 consecutive FD outpatients from three Guangdong hospitals according to Rome Ⅲ criteria between June and September in 2012.Of these,1057 patients with complete information were divided into group A as having weight loss more than 5％ (n =207) and group B as having weight loss less than 5％ (n =850).Nepean Dyspepsia Index-symptom checklist,appetite,Hamilton Rating Scale of Anxiety/Depression (HAMA/HAMD),Pittsburgh Sleep Quality Index (PSQI),Nepean Dyspepsia Index-quality of life,direct medical costs were used to compare the differences between the two groups.Results There were no significant differences in total scores of NDI-symptom checklist,the severity or bothersome items between two groups (t =-1.301、-0.918、0.138,P =0.193、0.359、0.890),but significant differences were observed in the frequence item and the rating of appetite as poor or very poor between two groups (t =-2.122,P =0.035 ;x2 =35.448,P =0.000 ;x2 =35.274,P =0.000).Significant differences were observed in the incidence of anxiety and depression and total scores of PSQI between the two groups (x2 =73.939,P =0.000;x2 =47.046,P =0.000 ; t =-4.904,P =0.000).Subscales scores of NDI-quality of life in group B were all significantly higher than those in group A (t =5.348、2.569、5.809、4.704,P =0.000、0.010、0.000、0.000).There were significant differences in the frequency of care-seeking and direct medical costs between the two groups (t =-4.860、-3.011,P =0.000、0.003).The frequency of gastroscopic examinations in group A was slightly higher than that in group B (t =-1.505,P =0.133).Conclusion FD patients with weight loss is not rare,and most of them have psychological disorders,loss of appetite and sleep disturbance.Moreover,care-seeking are more frequent,direct medical costs are more expensive,and impairment as assessed by NDI-QOL is more severe.Therefore,we should pay more attention to FD with weight loss in clinical setting.
