Objective To analyze the relationship between socioeconomic position and prevalence of hypertension, diabetes, coronary heart disease, stroke, chronic obstructive pulmonary diseases (COPD) and multi-morbidity among older adults in rural Yunnan Province. Methods A total of 4 833 older adults aged 60 years and over were selected by multi-stage stratified random sampling method in rural Yunnan Province. Information was acquired from questionnaire and health examination. Principal component analysis was used to construct the socioeconomic comprehensive score. Results The prevalence of hypertension, diabetes, stroke, coronary heart disease, COPD and multi-morbidity in target persons was 50.6%, 10.2%, 6.4%, 5.5%, 5.4% and 16.1% respectively. The prevalence of hypertension and diabetes was much higher in female compared with male (both P<0.05), in contrast the prevalence of COPD was much higher in male than female( 2=5.499, P=0.019)The prevalence of hypertension, stroke, coronary heart disease, COPD and multi-morbidity was increased with age(all P<0.05);Minority ethnic were more likely to develop hypertension, coronary heart disease, COPD and multi-morbidity than Han ethnic(all P<0.05). The results of multivariate logistic regression analysis showed that older adults with lower socioeconomic position had higher probability of suffering from hypertension, coronary heart disease, stroke, COPD and multi-morbidity (all P<0.05). Conclusions There are significant socioeconomic differences between socioeconomic position and prevalence of five major chronic diseases and multi-morbidity among older adults in rural Yunnan province. Older adults with low socioeconomic position should be key population for future prevention and control of chronic diseases.
Résumé
Background & objectives: Ampullary cancer is one of the periampullary tumours with better prognosis, but relapses occur early in some patients. This study was carried out to assess whether pancreatoduodenectomy (PDE, Whipple operation) could be a safe therapeutic procedure for elderly patients with periampullary tumours. Methods: Between 2005 and 2007, 19 patients (12 male, 7 female) aged over 65 yr (range 66 and 83 yr) with diagnosis of ampulloma were operated. Results: Of the 19 patients, 6 underwent local surgical ampullectomy with reinsertion of ductus choledochus and Wirsungi’s duct for benign or early cancer lesion and 13 underwent PDE (Whipple operation). Of these 13, only one was in T1 stage, one was in T4 stage, two patients were T3 and the rest in T2 stage. Lesion of lymphatic system had 40 per cent of patients in T2 stage and all in T3 and T4 stages. One patient died of pulmonary embolism several days after operation. Post-operative complications occurred in 3 cases: 1 patient with partial dehiscence of gastroenteroanastomosis – treated by conservative approach, 2 patients with dehiscence of pancreatojejunoanastomosis. Interpretation & conclusions: Diagnosis and therapy of ampullary tumours is multimodal. With careful patient selection, PDE can be performed in elderly people (>65 yr) safely. The post-operative morbidity in this group is essentially influenced by their multi-morbidity.
