BackgroundCardiovascular disease (CVD) is the leading cause of global disease burden. Although stroke was thought to be more prevalent than coronary heart disease (CHD) in Chinese, the epidemic pattern might have been changed in some rural areas nowadays. This study was to estimate up-to-date prevalence of CVD and its risk factors in rural communities of Fangshan District, Beijing, China.MethodsA cross-sectional population survey was carried out by stratified cluster sampling. A total of 58,308 rural residents aged over 40 years were surveyed by face-to-face interview and physical examination during 2008 and 2010. The standardized prevalence was calculated according to adult sample data of China's 5th Population Census in 2000, and the adjusted prevalence odds ratio (POR) was calculated for the association of CHD/stroke with its cardiovascular risk factors in multivariate logistic regression models.ResultsAge- and sex-standardized prevalence was 5.6% for CHD (5.2% in males and 5.9% in females), higher than the counterpart of 3.7% (4.7% in males and 2.6% in females) for stroke. Compared with previous studies, higher prevalence of 7.7%, 47.2%, 53.3% in males and 8.2%, 44.8%, 60.7% in females for diabetes, hypertension and overweight/obesity were presented accordingly. Moreover, adjusted POR (95% confidence interval) of diabetes, obesity, stage 1 and stage 2 hypertension for CHD as 2.51 (2.29 to 2.75), 1.53 (1.38 to 1.70), 1.13 (1.02 to 1.26) and 1.35 (1.20 to 1.52), and for stroke as 2.24 (1.98 to 2.52), 1.25 (1.09 to 1.44), 1.44 (1.25 to 1.66) and 1.70 (1.46 to 1.98) were shown respectively in the multivariate logistic regression models.ConclusionsHigh prevalence of CVD and probably changed epidemic pattern in rural communities of Beijing, together with the prevalent cardiovascular risk factors and population aging, might cause public health challenges in rural Chinese population.
BackgroundChinese menopausal women comprise a large population and the women in it experience menopausal symptoms in many different ways. Their health related quality of life (HRQOL) is not particularly well studied. Our study intends to evaluate the influence of menopause on HRQOL and explore other risk factors for HRQOL in rural China.MethodsAn interview study was conducted from June to August 2010 in Beijing based on cross-sectional design. 1,351 women aged 40–59 were included in the study. HRQOL was measured using the EuroQol Group’s 5-domain (EQ5D) questionnaire. Comparison of HRQOL measures (EQ5D index and EQ5D-VAS scores) was done between different menopausal groups. Logistic regression and multiple regression analysis were performed to adjust potential confounders and explore other risk factors for health problems and HRQOL measures.ResultsPostmenopausal women who had menopause for 2–5 years (+1b stage) were more likely to suffer mobility problems (OR = 1.835, p = 0.008) after multiple adjustment. Menopause was also related to impaired EQ5D index and EQ5D-VAS scores after adjustment for age. Among menopausal groups categorized by menopausal duration, a consistent decrement in EQ5D index and EQ5D-VAS scores, that is, worsening HRQOL, was observed (p < 0.05). Multiple regression analysis revealed low education level and physical activity were associated with EQ5D index (β = -0.080, p = 0.003, and β = 0.056, p = 0.040, respectively). Cigarette smoking and chronic disease were associated with EQ5D index (β = -0.135, p < 0.001 and β = -0.104, p < 0.001, respectively) and EQ5D-VAS (β = -0.057, P = 0.034 and β = -0.214, p < 0.001, respectively).ConclusionsReduction in physical function was found within the first five years after menopause. Worsening EQ5D index and EQ5D-VAS scores were related to menopause. Education level, physical activity, cigarette smoking, and chronic disease history were associated with HRQOL in middle aged Chinese rural women.
Abstract. The aim of the present retrospective analysis was to evaluate the treatment results for recurrent laryngeal cancer and to analyze the factors that may affect survival. A retrospective review was performed in 309 patients with recurrent laryngeal carcinoma, 224 of whom were treated between 1996 and 2009 at Sun Yat-Sen University Cancer Center (Guangzhou, Guangdong, China) and 85 of whom were treated between 2006 and 2013 at Zhejiang Cancer Hospital (Hangzhou, Zhejiang, China). The Kaplan-Meier method with the log-rank computation was used for the analysis of survival. The Cox proportional hazards model was applied to identify covariates that were significantly associated with overall survival. The actuarial 3-, 5-and 10-year survival rates were 68.9, 53.6 and 35.7%, respectively. Univariate analysis indicated that the following factors were associated with survival: Age, smoking index, tumor grade, primary tumor site, nodal status of the primary tumor, initial T stage, initial Union for International Cancer Control stage, initial treatment (radiotherapy or chemotherapy), disease-free interval, eligibility for surgery and extent of recurrence. Multivariate analysis of these factors indicated that the initial T stage, tumor grade, nodal status, disease-free interval and eligibility for surgery were significantly associated with survival. Overall, these results indicate that initial tumor stage T1 or T2, a high differentiation rate, no initial cervical lymph node metastasis, a long disease-free interval and a strong indication for salvage surgery are good prognostic factors for the survival of patients with recurrent laryngeal carcinoma.
