RESUMEN
Objective@#To investigate the prevalence characters of peripheral artery disease (PAD) and associated factors among people aged 35 and above in Beijing.@*Methods@#This was a cross-sectional study. A total of 5 208 community-based individuals aged equal and above 35 in Beijing were chosen with stratified multistage random sampling method. Structure questionnaire was used to collected the information of demographic factors, habits and chronic disease history. Ankle brachial blood pressure was detected and ankle brachial index (ABI) was calculated. ABI was used to diagnose PAD (ABI≤0.90). Based on the 2010 Beijing Municipal Population Census, the age-and gender-specific weight-adjusted sample was acquired to estimate the prevalence of PAD and corresponding 95% confidence intervals (CI). Multivariate logistic regression analysis was performed to estimate the associated factors of PAD.@*Results@#The age-and sex-standardized prevalence of PAD was 3.84% (200/5 208, 95%CI 3.32%-4.36%). There was no significant difference between male and female (3.83%(102/2 664, 95%CI 3.10%-4.56%) vs. 3.85% (98/2 544, 95%CI 3.10%-4.60%), P=0.965). The prevalence of PAD in urban was higher than that in rural (4.34% (163/3 755, 95%CI 3.69%-4.99%) vs. 2.55% (37/1 453, 95%CI 1.74%-3.36%), P=0.001). Furthermore, the prevalence of PAD increased with age (Ptrend<0.01), and the difference between genders did not change with ageing (all P>0.05). In addition, age (OR=1.03, 95%CI 1.01-1.04), urban (OR=1.52, 95%CI 1.08-2.12), smoking (OR=1.83, 95%CI 1.29-2.59), hypertension (OR=1.61, 95%CI 1.17-2.22) and diabetes (OR=1.44, 95%CI 1.08-1.93) were related with increased risk of PAD in logistic regression analysis models.@*Conclusions@#The prevalence of PAD increases with age in Beijing and there are significant difference between urban and rural on prevalence of PAD. Age, urban, smoking, hypertension and diabetes are related with increased risk of PAD.
RESUMEN
Objective To investigate the prevalence and risk factors of H-type hypertension among middle-aged and elderly people in Beijing community. Methods A cross-sectional study by recruiting 1 458 middle-aged and elderly people from a cohort of the "Beijing Longitudinal Study of Aging" in 2009 was conducted. All participants were asked to complete a standardized questionnaire, physical examination and laboratory examinations. Hyperhomocysteinemia was defined as homocysteine (Hcy) > 15 μmol/L, and H- type hypertension was defined as having hypertension and hyperhomocysteinemia simultaneously. The prevalence of H-type hypertension was estimated by using the results of 2000 Beijing population census to weight the data. Multivariate Logistic regression analysis was preformed to estimate the associated factors of H-type hypertension. Results The age was (69.48 ± 8.09) years, and the distribution of Hcy was skewed with the median of 16.56 μmol/L. After weight, the prevalence of hyperhomocysteinemia was 57.20% (834/1 458), and the prevalence of H-type hypertension was 35.32% (515/1 458), accounting for 59.47% (515/866) in patients with hypertension. The ageing, male, hyperuricemia, estimated glomerular filtration rate (eGFR) and insufficiency of fishes/ shrimps were independent risk factors of H-type hypertension ( OR = 2.30, 1.04, 1.02, 0.95 and 0.67; 95% CI 1.54-3.44, 1.02-1.06, 1.04-1.06, 0.94-0.97 and 0.46-0.97; P＜0.01 or＜0.05). Conclusions The proportion of H-type hypertension is high in the middle-aged and elderly people in Beijing community. Lowering uric acid, protection of renal function and intake sufficient fishes and shrimps might prevent and control H-type hypertension.

RESUMEN
Objective To investigate the risks of self-rated health in the ≥55-year elderly in Beijing and the occurrence of stroke.Methods The subjects (n=2 101;aged ≥55) from Beijing longitudinal study of aging (BLSA) were collected by Xuanwu Hospital,Capital Medical University from January 1992 to December 2016.One hundred and twenty-one subjects with stroke at baseline and 92 with incomplete information were excluded,and finally,1 888 elderly patients without cerebrovascular disease at baseline were included in the analysis.Based on the actual situation,the self-rated health was to identify an item that matched their current state from good,general to poor.The deadline for the survey was December 31,2012.The competitive risk model was used to assess the health self-rated status and the risk of stroke.Non-stroke deaths,including cancer and car accidents were treated as competitive events.Results Of the 1 888 subjects enrolled,946 (50.1%) self-rated health were good,616 (32.6%) were general,and 326 (17.3%) were poor;438 (23.2%) had stroke,751 (37.8%) had non-stroke death,and 699 (37.0%) were right censored data.Using the competing risk model and adjusting the age,sex,living area,marital status,education level,smoking,alcohol consumption,physical exercise,hypertension,diabetes mellitus,coronary heart disease,and body mass index,the occurrence of stroke in patients with poor self-rated health was 1.44 times (95%CI 1.11-1.87,P<0.01) as good as those who were good.Conclusion In the self-rated health of the elderly ≥55 years old in Beijing,the people with poor self-rated health increased the occurrence of stroke after considering the competitive risks.
RESUMEN
Objective To analyze the effect of stroke duration on the cognitive function in the elderly population in Beijing.Methods Based on the Research Project of Beijing Chronic Disease Combined with Common Elderly Syndrome Community Management Practices,a cross-sectional study was used.From July 2013 to December 2014,the old population in 4 districts and a county (Xicheng District,Fangshan District,Tongzhou District and Yanqing County) in Beijing were sampled with the multi-stage,randomized and stratified sampling.A total of 3 024 subjects were enrolled in the study.The data were obtained from the questionnaires and clinical examinations.Mini-Mental State Examination (MMSE) was used as the evaluation index of cognitive function.The subjects were divided into either a normal cognitive function group (MMSE>26,n=1 878) or a cognitive impairment group (MMSE≤26,n=1 146) according to the MMSE scores.A multiple logistic regression model was used to analyze the effects of hemorrhagic stroke,ischemic stroke,and asymptomatic stroke,as well as disease duration on cognitive function.Results After adjusting for the confounding factors,such as sex,age,educational level,marriage,smoking,and alcohol consumption,the risks of occurring cognitive impairment in patients with hemorrhagic stroke in stroke duration for 1-3,4-10 and >10 years were OR 3.019 (95％CI 0.974-9.361,P=0.056),8.652 (95％CI 2.924-25.601,P10 years were 1.000 (95％CI 0.636-1.571,P=1.000),1.874 (95％CI 1.231-2.853,P=0.003),2.439 (95％CI 1.386-4.291,P=0.002) times of those without occurring stroke population.Stroke duration for 4-10 years in patients with hemorrhagic stroke and stroke duration for 4-10 and >10 years in patients with ischemic stroke were all the risk factors for occurring cognitive dysfunction.Conclusion For patients with stroke,stroke duration or long-term effects has a certain impact on cognitive function.
RESUMEN
Objective To investigate the satlsfaction of senior outpatients over 60 years old,and explore the factors associated with their satisfaction so as to provide scientific references for improving quality of care at the hospital Methods A questionnaire survey was made by random sampling at the hospital.The outcomes subject to Ordinal regress Results The general satisfaction was as high as 82.77％ among these outpatients.Results of the Ordinal regression model showed seven factors significantly affecting such satisfaction rate,namely waiting time for registration,correct statement of medicine information,patience to hear patient's concerns,carefulness of inspection,time for doctor-patient communication,request for comments on therapy,and outpatient clinic seating conditions.Conclusion Senior outpatients tend to emphasize medical skills and medical service than waiting time at the hospital.This suggests better medical skills and service attitude as key to higher general satisfaction rate of senior outpatients.
