Methods A total of 19 363 participants （8635 males and 10 728 females） aged 〉35 years in geographically dispersed urban and rural regions of China were included in this cross-sectional survey. All participants received questionnaire, physical and blood examination. Echocardiography were performed for AF patients found in the survey. Results Of the 19 363 participants, 199 were diagnosed with AF. The estimated age-standardized prevalence of AF was 0.78% in men and 0.76% in women. The prevalence of AF in participants aged 〈60 years was 0.41% in men and 0.43% in women, and was 1.83% in both men and women aged 〉_60 years. About 19.0% of males and 30.9% of females with AF were diagnosed with valve disease. Age- and sex-adjusted multivariable logistic regression analysis revealed that myocardial infarction, left ventricular hypertrophy （LVH）, obesity, and alcohol consumption were associated with a increased risk of AF（P〈0.05）. Conclusion The age standardized prevalence of AF is 0.77% in the participants enrolled in the present study. The number of AF cases aged 〉35 years is 5.26 million according to 2010 Chinese Census. Most risk factors for AF, identified mainly in Western countries, are also detected in China.展开更多

This study aimed to assess the differences in proximal femoral geometry parameters between patients with femoral neck fractures and patients with intertrochanteric fractures to provide guidance for individualized customized prosthesis and accurate reconstruction of proximal femurs in elderly Chinese patients. Methods： We retrospectively studied the electronic medical records of 198 elderly patients over 65 years of age who were admitted to the orthopedic department with hip fractures between January 2017 and December 2017 in The Third Hospital, Hebei Medical University. Age, fracture site, gender, and proximal femoral geometry parameters （.neck shaft angle [NSA], center edge angle [CEA], femoral head diameter [FHD], femoral neck diameter [FND], femoral neck axial length [FNAL], hip axial length [HAL], and femoral shaft diameter [FSD]） were recorded. Student＇s t-test was used to compare the continuous variables, Chi-square test was used to analyze categorical variables, and multiple logistic stepwise regression analysis was used to evaluate the influencing factors of hip fracture type. Results： Statistically significant differences in NSA （137.63 ± 4.56° vs. 132.07 ± 4.17°, t = 1.598, P 〈 0.001）, CEA （37.62 ± 6.77° vs. 43.11 ±7.09°, t = 5.597, P 〈 0.001 ）, FND （35.21 ± 3.25 mm vs. 34.09 ±3.82 mm, t = 2.233, P = 0.027）, and FNAL （99.30 ± 7.91 mm vs. 103.58± 8.39 ram, t = 3.715, P 〈 0.001 ） were found between the femoral neck fracture group and femoral intertrochanteric fracture group. FHD, FND, FSD, HAL, and FNAL were different between sexes （all P 〈 0.001 ）. The greater NSA was the risk factor for femoral neck fractures （,odds ratio [OR]： 0.70, P 〈 0.001 ）, greater CEA and longer FNAL were risk factors for femoral intertrochanteric fractures （OR： 1.15, 1.17, all P 展开更多
