Oh TK, Song IA. Impact of prescribed opioid use on development of dementia among patients with chronic non-cancer pain. Sci Rep 2024; 14:3313. [PMID: 38331973 PMCID: PMC10853162 DOI: 10.1038/s41598-024-53728-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Accepted: 02/04/2024] [Indexed: 02/10/2024] Open
Abstract
We aimed to examine the association between opioid use and the development of dementia in patients with chronic non-cancer pain in South Korea. Data were extracted from the National Health Insurance Service database in South Korea. Adult patients diagnosed with musculoskeletal diseases with chronic non-cancer pain between 2010 and 2015 were included in the analysis. Patients who were prescribed opioids regularly and continuously for ≥ 90 days were classified as opioid users. In total, 1,261,682 patients with chronic non-cancer pain were included in the final analysis, of whom 21,800 (1.7%) were opioid users. From January 1, 2016 to December 31, 2020, 35,239 (2.8%) patients with chronic non-cancer pain were newly diagnosed with dementia. In the multivariable model, opioid users showed a 15% higher risk of developing dementia than the control group. Additionally, opioid users showed a 15% and 16% higher risk of developing Alzheimer's disease and unspecified dementia, respectively, than the control group, but did not show any significant differences for vascular dementia. Among adult patients with chronic non-cancer pain, opioid users were at a higher risk of developing dementia than the control group; the risk was significantly higher for Alzheimer's disease but not for vascular dementia in this study. Our results suggest that in patients with CNCP, public health strategies should target opioid users for early dementia detection and intervention.

Event History Analysis of Factors Affecting Survival of Older Adults in Taiwan. Healthcare (Basel) 2022; 10:healthcare10122439. [PMID: 36553963 PMCID: PMC9777609 DOI: 10.3390/healthcare10122439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2022] [Revised: 11/26/2022] [Accepted: 11/29/2022] [Indexed: 12/07/2022] Open
Abstract
(1) Background: Due to rapidly increasing average age of Taiwan's population, it is very important to analyze the factors affecting the survival of older adults. (2) Methods: In this study, the 1989 Taiwan Longitudinal Study on Aging, which lasted 22 years and consisted of seven surveys, was used. Furthermore, Cox and Aalen's time-dependent frailty models were used to analyze factors that affect the survival of older adults. (3) Results: Based on past literature, we selected 15 important factors that were closely associated with the survival of older adults and constructed six models based on these factors. The study results showed that, in addition to background characteristics, physical and mental conditions, activities of daily living (ADL), physical performance, and self-rated health had a huge association with the survival of older adults. (4) Conclusions: We selected ten variables (age, gender, population, education level, ADL status, physical performance, self-rated health, smoking, chewing betel nut, and the presence of a spouse), and their combinations were used to generate reduced models, which could be considered as important markers that affect and predict the survival of older adults.

Abstract
Childhood cancer survivors are at higher risk of developing neurocognitive deficits due to the intensive treatment they received at an early age. Most studies on childhood cancer survivorship have so far focused on the Western populations. Due to the ethnic, genetic, environmental, and cultural differences, clinical data of the Western populations may not be representative of Asian countries. This scoping review systematically summarized the existing clinical evidence of the neurocognitive impairment of Asian childhood cancer survivors. We searched the Embase and Medline databases for studies assessing the neurocognitive functions of survivors in Asia, who were diagnosed with cancer before the age of 19 and completed active treatment. The literature search identified 13 studies involving 2212 participants from five Asian countries: South Korea (n = 4, 30.8%), Taiwan (n = 3, 23.1%), Japan (n = 3, 23.1%), Hong Kong (n = 2, 15.4%), and Thailand (n = 1, 7.7%). The included studies focused on CNS tumors (n = 10, 76.9%), hematological malignancies (n = 7, 53.8%), or heterogeneous cancer diagnoses (n = 3, 23.1%). Collectively, mild-to-moderate impairment in intelligence was observed in 10.0 to 42.8% of survivors, which seemed higher than the reported rate in Western survivors. We speculate that the ethnic and genetic variations in drug responses and susceptibility to adverse chronic toxicities may have contributed to the differences in the prevalence and severity of neurocognitive impairment between these two populations. To better understand the effects of culturally relevant and region-specific environmental risk factors on the post-treatment neurocognitive development in cancer survivors, a holistic approach that addresses the complex interactions between biological, physical, and psychosocial factors is needed. This will aid the development of effective intervention strategies to improve the functional and psychosocial outcomes of cancer survivors in Asian societies.

Abstract
Study Objective: to investigate the factors related to diabetes mellitus in the middle-aged and over in Taiwan. Method: data from seven surveys (in 1989–2011) from the “Taiwan Longitudinal Study on Aging” (TLSA), among cohort B (above the age 60 in 1989), cohort A (aged 50–66 in 1996), and cohort C (aged 50–66 in 2003), were analyzed by the interval-censored Cox model. Results: in the early aging stage (aged 60–64), diabetes mellitus prevalence among the same age appeared the lowest in cohort B, followed by cohort A; cohort C reveals the highest than the young generation. Moreover, suffering from hypertension and kidney diseases are closely related to diabetes mellitus, with the diabetes mellitus suffering hazard ratio of 2.53 (95%: 2.35, 2.73) and 1.26 (95%: 1.11, 1.44) times, respectively. For people with fair and poor self-rated health, the risk of suffering from diabetes mellitus is 1.16 (95%: 1.07, 1.27) and 1.50 (95%: 1.35, 1.67) times compared to people with good self-rated health, respectively. Conclusions: in this study, it is considered that an advanced interval censoring model analysis could more accurately grasp the characteristics of factors in people who are middle-aged and over suffering from diabetes mellitus in Taiwan.

Abstract
Common inner ear diseases include peripheral vestibular disorder (PVD) and hearing impairment. The association between smoking and peripheral vestibular disorder (PVD) is unclear. We examined associations between smoking and new PVD events. In this retrospective study, we consecutively enrolled 393 participants aged ≥20 years [mean age 65.3 years; males 133 (33.8%)] treated for hypertension, dyslipidaemia, or diabetes mellitus at a primary care clinic between November 2011 and March 2013. Participants were categorized as ever-smokers (including current and past -smokers; divided per <30 and ≥30 pack-years), and never-smokers. New PVD events were reported over a 1-year follow-up period. Hazard ratios (HR) for new onset PVD were estimated using the Cox proportional hazard regression model. Compared to never-smokers, the adjusted HR was 2.22 for ever-smokers and 2.70 for all ever-smokers with ≥30 pack-years among all 393 participants. Among male participants, compared to never-smokers, the adjusted HR was 4.41 for ever-smokers with ≥30 pack-years. A smoking history of ≥30 pack-years was strongly associated with the risk of new onset PVD in males but not, females. This study may assist patients with smoking cessation for the prevention of new PVD events among males.

Abstract
Stroke is the third leading cause of death and the most common cause of complex disability in Taiwan. The annual age-standardized mortality rate of stroke is steadily decreasing between 2001 and 2012. The average years of potential life lost before age 70 for stroke is 13.8 years, ranked the fifth in the cause of death. Its national impact is predicted to be greater accompany aging population. The most common type of stroke was ischemic stroke in Taiwan. Small vessel occlusion was the majority of ischemic strokes subtype. Age, gender, hypertension, diabetes hyperlipidemia, obesity, atrial fibrillation, and smoking were important contributory factors to stroke morbidity. The standard treatment for acute ischemic stroke in Taiwan is providing the intravenous thrombolysis with recombinant tissue plasminogen activator (IV tPA) therapy for ischemic stroke patients within 3 hours of symptom onset. However, the rate of IV tPA therapy for patients with acute ischemic stroke is still low in Taiwan. Therefore, improving the public awareness of stroke warning signs and act on stroke and improving in-hospital critical pathway for thrombolysis would be the most important and urgent issues in Taiwan. To improve acute stroke care quality, a program of Breakthrough Series-Stroke activity was conducted from 2010 to 2011 and stroke centers were established in the medical centers. For the prevention of stroke, it was successful to increased annual smoke cessation rate through the 2009 Tobacco Hazards Prevention Act and decreased obesity rate through a nationwide weight-loss program conducted by Health Promotion Administration from 2011 to 2013 in Taiwan.

Abstract
BACKGROUND In China, there are 2.5 million new stroke cases each year and 7.5 million stroke survivors. However, stroke incidence in some island populations is obviously lower compared with inland regions, perhaps due to differences in diet and lifestyle. As the lifestyle in China has changed significantly, along with dramatic transformations in social, economic and environmental conditions, such changes have also been seen in island regions. Thus, we analyzed stroke in the Chinese island regions over the past 30 years. METHODS We conducted a systematic review to identify reliable and comparable epidemiologic evidence about stroke in the Chinese island regions between 1980 and 2013. Two authors independently assessed the eligibility and the quality of the articles and disagreement was resolved by discussion. Owing to the great heterogeneity among individual study estimates, a random-effects or fixed-effects model was used to incorporate the heterogeneity among records into a pooled estimate for age-standardized rates. Age-standardized rates were calculated by the direct method with the 2000 world population if included records provided the necessary information. RESULTS During the past three decades, the overall pooled age-standardized prevalence of stroke is 6.17 per 1000 (95% CI 4.56-7.78), an increase from 5.54 per 1000 (95% CI 3.88-7.20) prior to 2000 to 8.34 per 1000 (95% CI 5.98-10.69) after 2000. However, this difference was not found to be statistically significant. The overall pooled age-standardized incidence of stroke is 120.42 per 100,000 person years (95% CI 26.17-214.67). Between 1982 and 2008, the incidence of stroke increased and mortality declined over time. CONCLUSIONS Effective intervention and specific policy recommendations on stroke prevention should be required, and formulated in a timely fashion to effectively curb the increased trend of stroke in Chinese island regions.

Abstract
BACKGROUND Data is scarce on prevalence of extracranial carotid atherosclerosis (ECA) in strokes <50 years and its association with lifestyle factors. OBJECTIVE Study role of (a) ECA in non-cardio-embolic anterior circulation young strokes, and (b) smoking and alcohol in ECA. MATERIALS AND METHODS Cardiovascular risk factors and evidence of ECA on carotid doppler ultrasound (CDUS) was evaluated in an one-year preliminary cross-sectional study of consecutive strokes between 20 years and 49 years. Females were excluded. RESULTS There were 46 male strokes (mean age 38.26 yrs), 17.39% had hypertension, 2.23% had coronary artery disease; none was diabetic. Tobacco users and alcohol consumers were 24/46 (52.17%) cases each. ECA was found in 14/46 (30.44%) cases. Seven of these 14 (50%) i.e., 7/46 cases (15.21%) had carotid occlusion, four had <50%, three had >70% stenosis. 'Smoking and smokeless tobacco use' was found in 71.42% (10/14) symptomatic carotid lesions compared to 43.75% (14/32) strokes without carotid lesions. Prevalence odds ratio for tobacco use and ECA was 3.21 (95% CI: 0.83-12.44) while that of alcohol and ECA was 1.33 (95% CI: 0.38-4.72). CONCLUSION Prevalence of ECA in strokes <50 years was high due to lifestyle factors which predispose to atherosclerosis at younger age.

Abstract
Objective This study aimed to estimate the incidence and relative risk of stroke and post-stroke all-cause mortality among patients with bipolar disorder. Methods This study identified a study population from the National Health Insurance Research Database (NHIRD) between 1999 and 2003 that included 16,821 patients with bipolar disorder and 67,284 age- and sex-matched control participants without bipolar disorder. The participants who had experienced a stroke between 1999 and 2003 were excluded and were randomly selected from the NHIRD. The incidence of stroke (ICD-9-CM code 430–438) and patient survival after stroke were calculated for both groups using data from the NIHRD between 2004 and 2010. A Cox proportional-hazards model was used to compare the seven-year stroke-free survival rate and all-cause mortality rate across the two cohorts after adjusting for confounding risk factors. Results A total of 472 (2.81%) patients with bipolar disorder and 1,443 (2.14%) controls had strokes over seven years. Patients with bipolar disorder were 1.24 times more likely to have a stroke (95% CI = 1.12–1.38; p<0.0001) after adjusting for demographic characteristics and comorbid medical conditions. In addition, 513 (26.8%) patients who had a stroke died during the follow-up period. The all-cause mortality hazard ratio for patients with bipolar disorder was 1.28 (95% CI = 1.06–1.55; p = 0.012) after adjusting for patient, physician and hospital variables. Conclusions The likelihood of developing a stroke was greater among patients with bipolar disorder than controls, and the all-cause mortality rate was higher among patients with bipolar disorder than controls during a seven-year follow-up period.

Abstract
Cigarette smoking is a well-established risk factor for all forms of stroke. While both the general public and the global healthcare system are aware of the vascular risks associated with smoking, the prevalence of tobacco use has remained largely unchanged over the last quarter of a century. Approximately one in five US adults are classified as regular smokers, with the initiation of smoking typically occurring during the teenage years. Although the increased risk of stroke associated with smoking is generally acknowledged, it is less well recognized that considerable scientific evidence implicates a strong dose-response relationship between smoking and stroke risk. In this article, we summarize the literature regarding smoking-related stroke risk, the dose-response relationship, and the costs of this detrimental habit to both the individual and society as a whole.

Abstract
BACKGROUND Sexual activity in elderly people is a topic of growing interest but the relationships of sexual activity, libido and widowhood to mortality have been barely investigated. METHODS A total of 2,453 subjects enrolled from a nationwide survey on health status of residents aged 65 years or older in Taiwan between 1989 and 1991 were followed up until 31 December 2003 for ascertaining cause of death. Information on the frequency of sexual activity, libido (sexual desire), widowhood, disease status and relevant risk factors for risk of death at baseline were collected. RESULTS After controlling for age and relevant confounding factors, sexual activity was found to be inversely related to mortality {adjusted hazard ratio (aHR) = 0.67 [95% confidence interval (CI):0.56-0.80] for males, aHR = 0.84 (95% CI:0.65-1.09) for females and aHR = 0.72 (95% CI: 0.62-0.84) for both sexes combined}. Men having libido had lower mortality [aHR = 0.81 (95% CI:0.68-0.97)]. Widowhood status was positively correlated with mortality [aHR = 1.66 (95% CI: 1.25-2.19) for males, aHR = 1.33 (95% CI: 1.09 to -1.62) for females and aHR = 1.43 (95% CI: 1.21-1.68) for both sexes combined]. Sexual activity was also inversely related to mortality from stroke [aHR = 0.64 (95% CI: 0.41-1.00)]. CONCLUSIONS Sexual activity was associated with all-cause and cause-specific mortality independently of other risk factors. This finding was consistent with the elevated risk of death associated with widowhood for both men and women, and by the decreased mortality risk in men having libido.

Abstract
Elderly individuals with hypertension show specific characteristics as a result of advancing arteriosclerosis, a high frequency of isolated systolic hypertension, increased pulse pressure and orthostatic hypotension. The necessity to treat hypertension in the elderly, including isolated systolic hypertension, has been demonstrated in many large-scale intervention trials. Young-old (65-74 years of age) hypertensive patients should be treated the same as nonelderly hypertensive patients. In old-old (75-84 years of age) patients with mild hypertension (140-159/90-99 mm Hg), the recommended target blood pressure (BP) is <140/90 mm Hg. In old-old (75-84 years of age) and oldest-old (> or =85 years of age) patients with systolic BP > or =160 mm Hg, cautious treatment is required. An intermediate target BP of <150 mm Hg is appropriate, followed by a final target BP of <140 mm Hg, if tolerated. Nonmedical therapy, such as salt restriction, exercise and weight reduction, is useful in the elderly. However, individualised management of nonmedical therapy is necessary to avoid deterioration of quality of life resulting from strict management of the patient's lifestyle. Diuretics, calcium channel antagonists, ACE inhibitors and angiotensin II type 1 receptor antagonists have been established as first-line antihypertensive drugs in the elderly. Use of combination therapy helps to achieve target BPs. The starting dose of each drug should be half the usual dose for nonelderly patients, and may be increased at intervals of >4 weeks, with achievement of the target BP in 3-6 months or longer. In hypertensive patients with co-morbid diseases, the target BP should be determined individually and antihypertensive drugs selected bearing in mind the patient's clinical circumstances. Avoiding hypoperfusion of target organs is very important in elderly hypertensive patients. When treating hypertension in elderly patients, the approach should be to identify individual pathophysiological characteristics and lower the BP cautiously and slowly.

Abstract
Background Although smoking is known to be powerful risk factor for other vascular diseases, such as cardiac and peripheral vascular disease, only relatively recently has evidence for the role of smoking in the development of stroke been established. The reasons for this advance lie in the acknowledgement that stroke is a heterogeneous disease, in which its subtypes are associated with different risk factors. Furthermore, improvements in the stringency of epidemiological studies and the greater use of CT scanning have enabled the role of smoking in the development of stroke to be elucidated. Summary of review This is a qualitative examination of high quality epidemiological studies in which the role of smoking and passive smoking, as a risk factor for cerebral infarction, intracerebral haemorrhage and subarachnoid haemorrhage, is examined. In addition, the pathological mechanisms by which smoking or passive smoking may contribute to the development of stroke are reviewed. Conclusion Smoking is a crucial independent determinant of cerebral infarction and subarachnoid haemorrhage, however its role in intracerebral haemorrhage is unclear. Although studies are limited, there is evidence that exposure to passive smoking may also increase the risk of stroke. Smoking appears to be involved in the pathogenesis of stroke via direct injury to the vasculature and also by altering haemodynamic factors within the circulation. Importantly, smoking is modifiable risk factor for stroke. Therefore, the encouragement of smoking cessation may result in a substantial reduction in the incidence of this devastating disease.

Abstract
The major objective of the present study was to identify biologic and behavioral risk factors of cardiovascular disease (CVD) in the elderly population in Taiwan. It is hypothesized that the selected risk factors are significantly associated with the prevalence of CVD. Data came from a nationwide geriatric survey in 1991. Stratified proportional sampling was used to recruit 2,600 subjects. These were evaluated by family physicians working for the Departments of Family Medicine at four medical centers in four major cities in Taiwan. Univariate and multivariate logistic regression analyses were used to examine the associations between risk factors and the prevalence of CVD. The prevalence of CVD was 38.31%. Patients with CVD consistently had higher values for each selected risk factor except high-density lipoprotein-cholesterol (HDL-C) and glucose concentrations. The findings also indicated that hypertension, hypertriglyceridemia, low HDL-C concentration, ex-drinking status, and overweight were significantly associated with the prevalence of CVD among the elderly in Taiwan. The findings not only confirm the risk factors for CVD, but also invite more attention to be given to the importance of biologic and behavioral risk factors in CVD.

Abstract
The harmful effects of heavy alcohol use are well-documented and wide-ranging. Heavy drinking may cause or exacerbate cardiovascular disorders. The author suggests that effects of heavy alcohol consumption on the cardiovascular system may be mediated in part by the influence of alcohol-induced depression on the immune system. This hypothesis is based on the following data: (1) alcohol misuse may cause or exacerbate depression; (2) depressive disorders are associated with increased incidence, morbidity, and mortality of cardiovascular disorders; (3) the immune system may mediate effects of depressive disorders on the cardiovascular system. Further studies are needed to clarify the etiopathogenesis of alcohol-related disorders and develop new treatment modalities.

Abstract
OBJECTIVES To examine the health risks associated with smoking and blood pressure in Chinese hypertensive patients and to compare the benefit of antihypertensive drug treatment with the risk attributable to smoking. METHODS We used multiple Cox regression to correlate outcome with blood pressure and smoking status in 2284 older (aged > or = 60 years) patients enrolled in the Systolic Hypertension in China (Syst-China) Trial (systolic/diastolic blood pressure > or = 160/< 95 mmHg). RESULTS Median follow-up was 3.0 years. After adjustment for sex, age, active antihypertensive treatment and various entry characteristics, the relative hazard rates associated with smoking more than 20 cigarettes per day were 2.04 (P = 0.04), 4.66 (P < 0.001) and 4.74 (P = 0.002) for all-cause, noncardiovascular and cancer mortality, respectively. With similar adjustments applied, the relative hazard rates for total (fatal and non-fatal) stroke associated with smoking 10-20 and more than 20 cigarettes per day were 1.78 (P = 0.04) and 2.23 (P = 0.03), respectively. Furthermore, both smoking and systolic blood pressure were associated with higher risk of stroke. Compared with the overall risk in the whole group, treating 1,000 patients for 5 years prevented 40 [95% confidence interval (CI), 5-75] strokes in smokers as well as never smokers. Prognosis in never smokers and past smokers was similar. Quitting smoking had the potential to prevent 51 (95% CI, -21 to 122) strokes in untreated hypertensive patients and to prevent 45 (95% CI, - 14 to 104) additional strokes in treated patients, over and above the effects of antihypertensive treatment. If, in addition to stroke, non-cardiovascular mortality was also accounted for, the estimated absolute benefit of quitting smoking increased to 69 (95% CI, -18 to 155) and 97 (95% CI, 23-171) events in the untreated and the treated group, respectively. CONCLUSIONS In elderly Chinese patients, smoking was a risk factor for all-cause, non-cardiovascular and cancer mortality, as well as fatal and non-fatal stroke. The potential benefits of antihypertensive treatment and quitting smoking were approximately similar. In our view, these findings are important in terms of public health policies and health economics.

Abstract
BACKGROUND In Taiwan, distributions of body composition are usually generated for children, adolescent, and middle-aged groups. This study describes three anthropometric measures (i.e., height, weight, and body mass index [BMI]) of elderly persons in Taiwan. METHODS The data was derived from a prospective cross-sectional, population-based geriatric survey funded by the National Department of Health in Taiwan in 1991. A total of 2,600 subjects were successfully evaluated. A descriptive analysis was performed to generate distributions of height, weight, and BMI of elderly persons. Based on these descriptive data, the prevalence of overweight and obesity was estimated, and a cross-national comparison on the prevalence of obesity was made. RESULTS Age-group-specific means and standard deviations for height, weight, and BMI of Taiwanese elderly persons were presented. By gender, the elderly men were taller and heavier than the elderly women: however, the women had a higher mean value of BMI (kg/m2). The prevalence of overweight was 27.3% in men and 34.9% in women; the prevalence of obesity was 3.2% in men and 6.4% in women. The prevalence of obesity for the elderly men and women in Taiwan was lower than in Kuwait, Sweden, the United States, and the Native Americans, but higher than in Japan. CONCLUSIONS The comparison indicates cross-cultural differences existing in the prevalence of obesity, which may be due to aging, nutritional status, or environmental factors. For future research, the relationship of anthropometric data to socioeconomic status and behavioral factors will be examined.

Abstract
The relationship between alcohol consumption and stroke is uncertain. Heavy alcohol consumption has been associated with an increased risk of stroke, while light drinking appears to be protective. However, the evidence is not uniform. We sought to examine the relationship between alcohol consumption and stroke, according to stroke type. We performed a population-based case-control study from September 1990 to December 1991. The study comprised 467 incident cases of stroke and 477 controls aged between 40 and 85. Case was defined following WHO criteria and control was randomly selected from the study base population. Alcohol exposure was obtained by medical interview. We found that consumption of less than 30 g/day of alcohol was protective against all stroke types combined, the multivariated adjusted odds ratio (OR) was 0.58 (95% confidence interval [CI], 0.41-0.83). Moderate alcohol drinking is also protective against all cerebral infarction combined (OR = 0.53; 95% CI, 0.35-0.80) and cortical infarction (OR = 0.40; 95% CI, 0.18-0.86). Drinking up to 30 g/day of alcohol has a borderline protective effect on deep cerebral infarction (OR = 0.40; 95% CI, 0.16-1.02) and has no effect on intracerebral hemorrhage (OR = 0.88; 95% CI, 0.44-1.74). Heavy alcohol drinking, over 140 g/day, is a risk factor for all stroke types combined (OR = 3.2; 95% CI, 1.1-9.7), all cerebral infarction combined (OR = 5.0; 95% CI, 1.5-16.3), small deep cerebral infarction (OR = 9.7; 95% CI, 2.6-36.7), intracerebral hemorrhage (OR = 6.2; 95% CI, 1.3-24.0), and is marginally associated with superficial cerebral infarction (OR = 4.6; 95% CI, 1.0-20.6). The relationship between alcohol and stroke depends on the alcohol dose and the pathology of the disease. Atherosclerosis of the large and medium cerebral arteries is found mainly in superficial cerebral infarction, and this type of stroke shows a J-shaped relationship with alcohol similar to that found in coronary heart disease, suggesting that they are similar diseases. On the other hand, arteriosclerosis of the penetrating arteries has been found in deep cerebral infarction and intracerebral hemorrhage, while atherosclerosis is not prominent. This may explain why alcohol does not have a protective effect on cerebral hemorrhage whereas heavy drinking is a strong risk factor in these two types of stroke.

Abstract
In order to study the health status and prevalence of diseases in elderly Chinese people in Taiwan, a hospital-based, physician-conducted epidemiological survey was undertaken. Study subjects were people aged > or = 65 years who were randomly selected from four regions of Taiwan. A total of 2600 subjects were studied. Most of the study subjects visited the hospitals for detailed history taking, physical examination and laboratory tests, including urinalysis, blood chemistry, electrocardiography, and chest and lumbar spine radiography. The cardiovascular data of 2518 subjects (males 1283) comprised this report. The prevalence of hypertension in the aged Chinese in Taiwan was high in both males and females (males 33.2%, females 40.9%, combined 37%). Coronary artery disease was also common (11.4%), but the prevalence was relatively low compared with Western people. Other cardiovascular diseases such as aortic aneurysm and valvular heart disease were rare. About 70% of the electrocardiograms were found abnormal. This well-organized, large-scale epidemiological survey not only presents useful information for local medical care for the elderly but also provides important data for comparison between different people in the world.

Abstract
OBJECTIVES The purpose of this study was to identify risk factors for stroke and to estimate their relative importance in a large, nationally representative sample of very old men and women. METHODS The study was designed as a secondary analysis of the Longitudinal Study on Aging. Baseline (1984) in-person interview data were linked to Medicare hospitalization records for 1984 to 1991. Participants were 6,071 noninstitutionalized adults 70 years old or older at baseline. Hospitalization for ischemic stroke was defined as having one or more episodes with a primary discharge diagnosis containing ICD-9-CM codes of 433.0-434.9, 436, and 437.0-437.1. Multivariable proportional hazards regression was used to estimate the risks associated with previously identified epidemiologic factors. RESULTS Five hundred and three persons (8.3%) had at least one primary discharge diagnosis of ischemic stroke. In descending order of importance-based on the partial r statistics associated with their adjusted hazards ratios (AHRs), the salient risk factors were having a previous history of stroke (AHR = 2.86), age (AHR = 1.04 per year), diabetes (AHR = 1.78), male gender (AHR = 1.42), lower body limitations (AHR = 1.09 per limitation), arthritis (AHR = 0.74), hypertension (AHR = 1.29), and poverty (AHR = 1.33). CONCLUSION Patients presenting with the high risk factors identified in this study should be considered for further evaluation and monitoring. Current protocols for the therapeutic management of these higher risk patients should be considered, and compliance should be encouraged.
