Background:Irritable bowel syndrome(IBS)is a commonly seen functional intestinal disorder. Dietary factors are important factors affecting the abdominal symptoms of IBS patients. Aims:To investigate the effect of dietary factors on abdominal symptoms of IBS and the application of dietary adjustment strategy in patients lived in Xian,Shaanxi Province and the surrounding areas. Methods:Fifty-four outpatients with abdominal complaints who met the Rome Ⅲ criteria of IBS from Feb. 2015 to Jul. 2015 at the Second Affiliated Hospital of Xian Jiaotong University were enrolled. Twenty healthy volunteers were served as controls. All subjects completed a questionnaire containing issues mainly on IBS symptoms, eating habits,dietary factors causing abdominal symptoms,and the patients’coping styles. Results:Compared with healthy controls,more rice and less spicy food,fatty food,raw/ cold food,acidic beverages and alcohol drinking were observed in diet of IBS patients(P all < 0. 05). Abdominal symptoms of IBS patients could be caused or exacerbated predominantly by cold food(55. 6% ),fatty food(55. 6% ),raw food(48. 1% ),meat(48. 1% )and spicy food (40. 7% ). More than half of the IBS patients(63. 0% ) adopted an elimination diet to minimize their abdominal symptoms. Spicy food(59. 3% ),raw food(48. 1% ),cold food(44. 4% ),fatty food(44. 4% )and meat(37. 0% ) were the most frequently eliminated classes of food. Conclusions:Dietary factors can affect the abdominal symptoms of IBS in patients lived in Xian,Shaanxi Province and the surrounding areas and elimination diet based on foods they perceive as problematic is widely used. The classes of food and eating habits causing abdominal symptoms are quite different between domestic and overseas IBS patients.

Objective To analyze the prevalence and economic burden of diabetes in Guandu district of Kunming. Methods We used probability proportional to size (PPS) sampling method to select representative sample of 4595 residents aged 18 or over from this district. Each participant received face to face questionnaire interview and physical examination. We applied different methods to measure the direct,indirect and intangible costs of diabetes. Results In the study population, the overall prevalence of diabetes was 6.2%,and females had higher prevalence of diabetes than males (6.2%vs. 5.6%, <0.05) . The DALY/1000 population of diabetes was 3.52, among which males and females were 5.18 and 6.70, respectively. Mean unit direct costs, indirect costs and intangible costs of diabetes were 3464.49 Yuan,84.48 Yuan and 4 045.97 Yuan,respectively. The total economic burden of diabetes was 401.84 million Yuan. Intangible costs represented the largest component of economic burden of diabetes,followed by direct costs. Conclusion The huge economic burden of diabetes has become the cause for concern in Guandu district. Effective measures are needed to reduce the economic burden of diabetes.
