RESUMEN
The world healthcare system is actively seeking possible solutions for the rapid growth of kidney disease threats. The Taiwan Renal Data System (TWRDS) was central in assisting kidney health and care policymaking to reduce end-stage kidney disease incidence and mortality. This article summarizes the TWRDS framework, recent applications, and developments to provide new insights for some international researchers to promote planetary kidney health. The TWRDS originated in 1987 for the accreditation and quality monitoring of dialysis units and was connected with enriched health claim databases after the implementation of universal national health insurance in Taiwan in 1995. As a healthcare information centre, TWRDS has published annual reports forming indispensable instructions for renal care improvement since 2014. The TWRDS possesses three main functions: (1) kidney disease surveillance; (2) offering rich materials for research purposes; (3) achieving precision prevention and care through complex algorithms. In the new era, TWRDS can help build a more resilient society against communicable disease threats by integrating remote sensor techniques for developing future remote healthcare structures, as well as identifying kidney health inequity populations and promoting healthcare resources distributed equity. The global healthcare system is facing escalating burdens of non-communicable disease care due to the rapidly growing elderly population. Therefore, a considerable-scale data system is an essential decision-supportive tool in promoting an evidence-based, resilient, sustainable, equity care environment. Undoubtedly, TWRDS experience is a practical example of leveraging healthcare providers' decisions, care outcomes, and renovation.

OBJECTIVES: To assess temporal patterns and regional differences in the incidence rate, and factors associated with survival of urinary tract urothelial carcinoma. METHODS: The medical records of 8830 patients with new diagnoses of urinary tract urothelial carcinoma in the years 2001-2010 were retrieved from Taiwan National databases. Temporal trends, regional disparity and related survival factors were evaluated using the Cochran-Armitage trend test, local Moran's I statistic and log-rank test, respectively. RESULTS: The annual urinary tract urothelial carcinoma incidence rates (standardized by age) were steady at approximately 3.14-3.41 per 100 000 person-years. Notably, women had a significantly higher annual urinary tract urothelial carcinoma incidence than men in most of the years studied (range of female-to-male annual standardized rate ratio: 2.08-3.25), and diabetes prevalence in urinary tract urothelial carcinoma increased significantly from 12.3% to 23.4% per year over the 10 years. High urinary tract urothelial carcinoma incidence cluster areas other than the latest endemic area of "blackfoot disease" were newly identified by local Moran's I statistic (P < 0.05). Furthermore, older age, male sex, end-stage kidney disease and more advanced tumor grade were associated with lower 5-year overall survival probabilities in the 2001-2015 cohort. CONCLUSIONS: The incidence and survival of urinary tract urothelial carcinoma over the decade 2001-2010 were different according to population and regional features. Various urinary tract urothelial carcinoma screening, prevention, treatment and care plans should be developed depending on age, sex, comorbidity and area of residence.

BACKGROUND/PURPOSE: Hepatitis B virus (HBV), hepatitis C virus (HCV), and tuberculosis (TB) infections affect patient morbidity and mortality and challenge infection control procedures within dialysis facilities. Thus, updated information on the yearly infection trends in the dialysis population is pivotal to preventing and improving the management of these infectious diseases. METHODS: This study used reimbursement data from the Taiwan National Health Insurance Research Database. Long-term hemodialysis (HD) patients were defined as those receiving regular HD for more than 3 months. Treated HBV, HCV, and TB cases were defined according to the diagnosis codes, together with specified prescriptions. Liver malignancy and liver-related mortality were determined by the disease diagnosis. RESULTS: The long-term HD population in Taiwan grew from 57,539 in 2010 to 74,203 in 2018. The mean number of treated HBV, HCV, and TB cases in the HD population was 254 (3.9 per thousand HD patients), 136 (2.0 per thousand), and 165 (2.6 per thousand), respectively. An increasing trend of treated viral hepatitis and a mildly decreasing trend in treated TB were observed. Liver outcome showed an increasing trend in liver malignancy prevalence and a stationary trend of liver-related mortality. Treated HBV and TB, liver malignancy, and liver-associated mortality were higher in men than women (all p < 0.001). The burden of liver complications was higher in southern Taiwan. CONCLUSION: The increasing yearly trend of treated HBV and HCV and a stable trend of treated TB provide evidence for further infection control management and risk population identification of the HD population.

BACKGROUND: The Taiwanese government launched a universal pay-for-performance (P4P) program in 2006 to promote multidisciplinary care for patients with stage 3b-5 chronic kidney disease (CKD). This study aimed to understand the enrollments, care processes, and outcomes of the P4P program between 2010 and 2018. METHODS: We conducted a population-based study using the Taiwan National Health Insurance Research Data. We divided the incident dialysis population into joining and not joining P4P groups based on whether patients had joined the pre-ESRD program before dialysis or not. Trends in the medications prescribed, anemia correction, vascular access preparation before dialysis initiation, and cumulative survival rate were compared. RESULTS: The program included more than 100,000 patients with late-stage CKD. Enrollment increased by almost 100% from 2010 to 2018, with increases seen in those over 75 years old (127.5%), male (96.7%), and earlier CKD stages (≥35% stage 3b in 2018). Females were more likely to stay being enrolled. The joining P4P group was prescribed more appropriate medications, such as erythropoietin-stimulating agents and statins. However, a high number of patients were still prescribed metformin (≥40%) and non-steroidal anti-inflammatory drugs (≥20%). Compared to the not joining P4P group, the patients in the P4P group had better anemia management, dialysis preparation, and post-dialysis survival. CONCLUSION: The patients in the joining P4P program group were delivered more appropriate CKD care and were associated with better survival outcomes. Polices and action plans are needed to extend the coverage of and enrollment in the P4P program.

BACKGROUND: Patients with chronic kidney disease (CKD) often have structural abnormalities of the heart due to pressure and volume overload. The aim of this study was to evaluate associations between echocardiographic parameters and renal outcomes (estimated glomerular filtration rate [eGFR] slope and progression to dialysis) in patients with stage 3-5 CKD. METHODS: This longitudinal study enrolled 419 patients. Changes in renal function were assessed using the eGFR slope. Rapid renal progression was defined as an eGFR slope < -3 mL/min/1.73 m2/year, and the renal endpoint was defined as commencing dialysis. RESULTS: Increased left atrial diameter (LAD), ratio of left ventricular mass to body surface area (LVM/BSA), ratio of LVM to height2.7 (LVM/ht2.7), and ratio of observed to predicted LVM (o/p LVM) were associated with eGFR slope in an adjusted model, but left ventricular ejection fraction (LVEF) was not. Furthermore, LAD ≥ 4.7 cm, LVM/BSA > 115 g/m2 in males and > 95 g/m2 in females, and LVM/ht2.7 > 48 g/ht2.7 in males and > 44 g/ht2.7 in females were correlated with progression to dialysis, but o/p LVM and LVEF were not. The maximum change in χ2 change to predict renal outcomes was observed for LAD, followed by LVM/BSA and LVM/ht2.7. CONCLUSIONS: A large LAD and increased LVM, regardless of how it was measured (LVM/BSA, LVM/ht2.7 and o/p LVM), were correlated with adverse renal outcomes in patients with CKD stage 3-5. LAD had superior prognostic value to LVM and LVEF.

BACKGROUND: Negatively charged very-low-density lipoprotein (VLDL-χ) in metabolic syndrome (MetS) patients exerts cytotoxic effects on endothelial cells and atrial myocytes. Atrial cardiomyopathy, manifested by atrial remodeling with a dilated diameter, contributes to atrial fibrillation pathogenesis and predicts atrial fibrillation development. The correlation of VLDL-χ with atrial remodeling is unknown. This study investigated the association between VLDL-χ and remodeling of left atrium. METHODS: Consecutively, 87 MetS and 80 non-MetS individuals between 23 and 74 years old (50.6% men) without overt cardiovascular diseases were included in the prospective cohort study. Blood samples were collected while fasting and postprandially (at 0.5, 1, 2, and 4 h after a unified meal). VLDL was isolated by ultracentrifugation; the percentile concentration of VLDL-χ (%) was determined by ultra-performance liquid chromatography. The correlations of left atrium diameter (LAD) with variables including VLDL-χ, LDL-C, HDL-C, triglycerides, glucose, and blood pressure, were analyzed by multiple linear regression models. A hierarchical linear model was conducted to test the independencies of each variable's correlation with LAD. RESULTS: The mean LAD was 3.4 ± 0.5 cm in non-MetS subjects and 3.9 ± 0.5 cm in MetS patients (P < 0.01). None of the fasting lipid profiles were associated with LAD. VLDL-χ, BMI, waist circumference, hip circumference, and blood pressure were positively correlated with LAD (all P < 0.05) after adjustment for age and sex. Significant interactions between VLDL-χ and blood pressure, waist circumference, and hip circumference were observed. When adjusted for obesity- and blood pressure-related variables, 2-h postprandial VLDL-χ (mean 1.30 ± 0.61%) showed a positive correlation with LAD in MetS patients. Each 1% VLDL-χ increase was estimated to increase LAD by 0.23 cm. CONCLUSIONS: Postprandial VLDL-χ is associated with atrial remodeling particularly in the MetS group. VLDL-χ is a novel biomarker and may be a therapeutic target for atrial cardiomyopathy in MetS patients. TRIAL REGISTRATION: ISRCTN 69295295 . Retrospectively registered 9 June 2020.

BACKGROUND: Incidence of renal dysfunction and risks of progression to end-stage renal disease (ESRD) were reported higher in upper urinary tract urothelial carcinoma (UTUC) than in renal cell carcinoma (RCC) patients after unilateral nephrectomy. METHODS: Totally 193 renal cancer patients, including 132 UTUC and 61 RCC, were studied to clarify whether the pathological changes of the kidney remnant removed from nephrectomy and the clinical factors might predict the risk of ESRD. Renal tubulointerstitial (TI) score and global glomerulosclerosis (GGS) rate were examined by one pathologist and two nephrologists independently under same histopathological criteria. RESULTS: The glomerular filtration rates at the time of surgery were lower in UTUC than RCC groups (p < 0.001). Average GGS score and average TI rate were higher in UTUC than in RCC groups (p < 0.001; p < 0.001). Competitive risk factor analysis revealed that abnormal GGS rate not related to age, predominant in UTUC with pre-existing renal function impairment, was a histopathological predictor of poor renal outcomes (creatinine doubling or ESRD) within 5 years in UTUC patients. CONCLUSION: Pre-existing renal function and pathological change of kidney remnant in both UTUC and RCC have the value for prediction of renal outcomes.

BACKGROUND: The relation of dialysis to tumor recurrence in patients with upper tract urothelial cancer (UTUC) is unknown; however, a limited number of small-scale studies suggest that patients with renal diseases prior to UTUC are more likely to exhibit bladder recurrence. We performed a population-based analysis to determine the effect of dialysis on bladder recurrence for patients with UTUC. METHODS: This retrospective cohort study included patients diagnosed with UTUC (2002-2007) from the Taiwan National Cancer Registry and divided them into two groups-dialysis and non-dialysis groups. These patients were followed up until bladder recurrence, death, or the end of 2010. Competing risk analyses adjusting covariates and death were applied to determine the relation of dialysis and bladder recurrence. RESULTS: Of the 5141 eligible patients, 548 (10.7%) were undergoing dialysis. The cumulative bladder recurrence was significantly higher in the dialysis group than in the non-dialysis group (29% vs. 21%, modified log-rank p < 0.001). In the multivariable analysis, the dialysis group exhibited a 64% increased bladder recurrence risk (cause-specific hazard ratio 1.64, 95% confidence interval 1.34-2.01, p < 0.001), which was confirmed using stratification and propensity score weighting methods. The other prognostic factors for bladder recurrence were sex, diabetes, cardiac disorder, Charlson Comorbidity Index, and tumor grade. CONCLUSIONS: Despite unknown reasons, approximately one-tenth of patients with UTUC have experienced dialysis treatment. Patients undergoing dialysis have a higher risk of bladder recurrence. Various treatment and screening strategies should be developed for dialysis and non-dialysis patients.

BACKGROUND: Incidence of dementia is growing rapidly and affects many people worldwide. Type 2 diabetes mellitus (DM) might link cognitive decline and dementia, but the reasons for this association remain unclear. Our study explored the factors associated with type 2 DM in patients with dementia. METHODS: Patients (n = 40,404) with vascular dementia were identified in Taiwan's 1997 to 2008 National Health Insurance Research Database and divided into a DM group and non-DM group. Eleven comorbidities were identified and categorized into four groups: cardiovascular and cerebrovascular diseases, digestive system diseases, renal and metabolic system diseases, and cancer. The associations of these factors with type 2 DM were explored through multivaraible logistic regression. RESULTS: Of the patients with dementia, 22.5% had DM. Associated with a higher likelihood of DM in this population were female sex (adjusted odds ratio [OR]: 1.44, 95% confidence interval [CI]: 1.36-1.52), young age (range of adjusted OR: 0.55-1.13), low income (range of adjusted OR: 1.09-1.18), and renal and metabolic system diseases (OR: 2.81, 95% CI: 2.64-2.98). CONCLUSIONS: The findings of this study suggest that clinicians should encourage patients with dementia to receive regular glucose impairment screening if they are female, have low socioeconomic status, or have renal or metabolic diseases.

BACKGROUND: The National Health Insurance Administration in Taiwan initiated a nationwide pre-end-stage renal disease (ESRD) pay-for-performance (P4P) programme at the end of 2006 to improve quality of care for chronic kidney disease (CKD) patients. This study aimed to examine this programme's effect on patients' clinical outcomes and its cost-effectiveness among advanced CKD patients. METHODS: We conducted a longitudinal observational matched cohort study using two nationwide population-based datasets. The major outcomes of interests were incidence of dialysis, all-cause mortality, direct medical costs, life years (LYs) and incremental cost-effectiveness ratio comparing matched P4P and non-P4P advanced CKD patients. Competing-risk analysis, general linear regression and bootstrapping statistical methods were used for the analysis. RESULTS: Subdistribution hazard ratio (95% confidence intervals) for advanced CKD patients enrolled in the P4P programme, compared with those who did not enrol, were 0.845 (0.779-0.916) for incidence of dialysis and 0.792 (0.673-0.932) for all-cause mortality. LYs for P4P and non-P4P patients who initiated dialysis were 2.83 and 2.74, respectively. The adjusted incremental CKD-related costs and other-cause-related costs were NT$114 704 (US$3823) and NT$32 420 (US$1080) for P4P and non-P4P patients who initiated dialysis, respectively, and NT$-3434 (US$114) and NT$45 836 (US$1572) for P4P and non-P4P patients who did not initiate dialysis, respectively, during the 3-year follow-up period. CONCLUSIONS: P4P patients had lower risks of both incidence of dialysis initiation and death. In addition, our empirical findings suggest that the P4P pre-ESRD programme in Taiwan provided a long-term cost-effective use of resources and cost savings for advanced CKD patients.

The evidence on whether Chinese herbal medicines affect outcome in patients with chronic kidney disease (CKD) is limited. Here we retrospectively explored the association of prescribed Chinese herbal medicine use and the risk of end-stage renal disease (ESRD) in patients with CKD. Patients with newly diagnosed CKD in the Taiwan National Health Insurance Research Database from 2000 to 2005 were categorized into new use or nonuse of prescribed Chinese herbal medicine groups. These patients were followed until death, dialysis initiation, or till the end of 2008. Among the 24,971 study patients, 11,351 were new users of prescribed Chinese herbal medicine after CKD diagnosis. Overall, after adjustment for confounding variables, the use group exhibited a significant 60% reduced ESRD risk (cause-specific hazard ratio 0.41, 95% confidence interval 0.37-0.46) compared with the nonuse group. The change was significantly large among patients using wind dampness-dispelling formulas (0.63, 0.51-0.77) or harmonizing formulas (0.59, 0.46-0.74), suggesting an independent association between specific Chinese herbal medicines and reduced ESRD risk. The findings were confirmed using propensity score matching, stratified analyses, and three weighting methods. However, dampness-dispelling and purgative formulas were associated with increased ESRD risk. Thus, specific Chinese herbal medicines are associated with reduced or enhanced ESRD risk in patients with CKD.
RESUMEN
Tuberculosis (TB) and cirrhosis of the liver are both endemic in many regions of the world. However, the risk of TB in cirrhotic patients has rarely been investigated. A nationwide cohort study was conducted to elucidate and characterize the association between cirrhosis and TB in Taiwan. The study included 41,076 cirrhotic patients and 204,244 noncirrhotic controls from 1998 through 2007. Cirrhotic and noncirrhotic subjects were matched 1:5 on age and sex. A total of 957 of 41,076 (2.32%) cirrhotic patients developed TB, yielding a rate that was significantly higher than that of the 955 of 204,244 (0.46%) noncirrhotic patients (P < 0.001). In a Cox regression model adjusted for age, sex, and underlying medical disorders, a significantly higher active TB rate was maintained for cirrhotic patients compared with their noncirrhotic counterparts (adjusted hazard ratio = 3.55, 95% confidence interval (CI): 3.08, 4.09; P < 0.001). Alcoholism and hepatitis C infection were associated with significantly higher TB risk with adjust hazard ratios of 2.18 (95% CI: 1.86, 4.09; P < 0.001) and 1.18 (95% CI: 1.02, 1.30; P < 0.001), respectively. Cirrhotic patients have a greater risk of TB than noncirrhotic patients, particularly those with alcoholism and hepatitis C infection.

Greater variability in renal function is associated with mortality in patients with chronic kidney disease (CKD). However, few studies have demonstrated the predictive value of renal function variability in relation to renal outcomes. This study investigates the predictive ability of different methods of determining estimated glomerular filtration rate (eGFR) variability for progression to renal replacement therapy (RRT) in CKD patients. This was a prospective observational study, which enrolled 1,862 CKD patients. The renal end point was defined as commencement of RRT. The variability in eGFR was measured by the area under the eGFR curve (AUC)%. A significant improvement in model prediction was based on the -2 log likelihood ratio statistic. During a median 28.7-month follow-up, there were 564 (30.3%) patients receiving RRT. In an adjusted Cox model, a smaller initial eGFR AUC%_12M (P < 0.001), a smaller peak eGFR AUC%_12M (P < 0.001), and a larger negative eGFR slope_12M (P < 0.001) were associated with a higher risk of renal end point. Two calculated formulas: initial eGFR AUC%_12M and eGFR slope_12M were the best predictors. Our results demonstrate that the greater eGFR variability by AUC% is associated with the higher risk of progression to RRT.

This retrospective study was conducted at a medical center in southern Taiwan to assess the accuracy of the Hendrich II Fall Risk Model (HIIFRM) in predicting falls. Sensitivity, specificity, accuracy, and optimal cutoff points were analyzed using receiver operating characteristic (ROC) curves. Data analysis was conducted using information from the electronic medical record and patient safety reporting systems, capturing 303 fall events and 47,146 non-fall events. Results revealed that at the standard threshold of HIIFRM score ≥5, the median score in the fall group was significantly higher than in the non-fall group. The top three units with HIIFRM scores exceeding 5 were the internal medicine (50.6%), surgical (26.5%), and oncology wards (14.1%), indicating a higher risk of falls in these areas. ROC analysis showed an HIIFRM sensitivity of 29.5% and specificity of 86.3%. The area under the curve (AUC) was 0.57, indicating limited discriminative ability in predicting falls. At a lower cutoff score (≥2), the AUC was 0.75 (95% confidence interval: 0.666-0.706; p < 0.0001), suggesting acceptable discriminative ability in predicting falls, with an additional identification of 101 fall events. This study emphasizes the importance of selecting an appropriate cutoff score when using the HIIFRM as a fall risk assessment tool. The findings have implications for fall prevention strategies and patient care in clinical settings, potentially leading to improved outcomes and patient safety.

CONTEXT: Type 2 diabetes (T2D) is the major contributor to chronic kidney disease and end-stage kidney disease (ESKD). The influence of trimethylamine N-oxide (TMAO) on kidney outcomes in T2D remains unclear. OBJECTIVE: To examine the association between fasting serum TMAO levels and adverse kidney outcomes in patients with T2D. METHODS: Between October 2016 and June 2020, patients with T2D were recruited and monitored every 3 months until December 2021. Serum TMAO levels were assessed using liquid chromatography-mass spectrometry. The primary kidney outcomes were doubling of serum creatinine levels or progression to ESKD necessitating dialysis; the secondary kidney outcome was a rapid 30% decline in estimated glomerular filtration rate within 2 years. All-cause mortality was also evaluated. RESULTS: Among the 440 enrolled patients with T2D, those in the highest serum TMAO tertile (≥0.88â µM) were older, had a longer diabetes duration, elevated blood urea nitrogen, and lower estimated glomerular filtration rate. Over a median follow-up period of 4 years, 26 patients (5.9%) had a doubling of serum creatinine level or progression to ESKD. After propensity score weighting, the patients in the highest serum TMAO tertile had a 6.45-fold increase in the risk of doubling of serum creatinine levels or progression to ESKD and 5.86-fold elevated risk of rapid decline in kidney function compared with those in the lowest tertile. Additionally, the stepwise increase in serum TMAO was associated with all-cause mortality. CONCLUSION: Patients with T2D with elevated circulating TMAO levels are at higher risk of doubling serum creatinine, progressing to ESKD, and mortality. TMAO is a potential biomarker for kidney function progression and mortality in patients with T2D.

INTRODUCTION: Chronic kidney disease is related to neurodegeneration and structural changes in the brain which might lead to cognitive decline. The Fazekas scale used for assessing white matter hyperintensities (WMHs) was associated with poor cognitive performance. Therefore, this study investigated the associations between the mini-mental status examination (MMSE), Montreal cognitive assessment (MoCA), cognitive abilities screening instrument (CASI), and Fazekas scale in patients under hemodialysis (HD). METHODS: The periventricular (PV) WMHs and deep WMHs (DWMHs) in brain magnetic resonance images of 59 patients under dialysis were graded using the Fazekas scale. Three cognition function tests were also performed, then multivariable ordinal regression and logistic regression were used to identify the associations between cognitive performance and the Fazekas scale. RESULTS: There were inverse associations between the three cognitive function tests across the Fazekas scale of PVWMHs (p = .037, .006, and .008 for MMSE, MoCA, and CASI, respectively), but the associations were attenuated in the DWMHs group. In CASI, significant differences were identified in short-term memory, mental manipulation, abstract thinking, language, spatial construction, and name fluency in the PVWMHs group. However, DWMHs were only significantly correlated with abstract thinking and short-term memory. CONCLUSION: An inverse correlation existed between the Fazekas scale, predominantly in PVWMHs, and cognition in patients undergoing HD. The PVWMHs were associated with cognitive performance assessed by MMSE, MoCA, and CASI, as well as with subdomains of CASI such as memory, language and name fluency in patients undergoing HD.

The worldwide prevalence and incidence rates of end-stage renal disease have been increasing, and the trend is pronounced in Taiwan. This is especially evident in southern Taiwan, where the wet-bulb globe temperature (WBGT) is consistently higher than in other regions. The association between kidney function and WBGT has not been fully investigated. Therefore, the aim of this study was to evaluate the association between estimated glomerular filtration rate (eGFR) and WBGT and variations in this association across different geographic regions in Taiwan. We used the Taiwan Biobank (TWB) to obtain data on community-dwelling individuals, linked these data with WBGT data obtained from the Central Weather Bureau and then processed the data using a machine learning model. WBGT data were recorded during the working period of the day from 8:00 a.m. to 5:00 p.m. These data were then compiled as 1-year, 3-year and 5-year averages, recorded prior to the survey year of the TWB of each participant. We identified 114 483 participants who had WBGT data during 2012-2020. Multivariable analysis showed that, in northern Taiwan, increases in 1- and 3-year averages of WBGT during the working period (ß = -0.092, P = .043 and ß = -0.193, P < .001, respectively) were significantly associated with low eGFR. In southern Taiwan, increases in 1-, 3- and 5-year averages of WBGT during the working period (ß = -0.518, P < .001; ß = -0.690, P < .001; and ß = -0.386, P = .001, respectively) were gnificantly associated with low eGFR. These findings highlight the importance of heat protection for people working outdoors or in high-temperature environments as a measure to prevent negative impacts on kidney function. Moreover, we observed that in southern Taiwan, every 1°C increase in WBGT had a greater impact on the decrease in eGFR compared with other regions in Taiwan.
RESUMEN
BACKGROUND: Areca nut chewing is associated with the risk of obesity, metabolic syndrome, hypertension, and cardiovascular mortality. Although a few case reports or case series have suggested the link between areca nut chewing and cardiac arrhythmias, information about the relationship between areca nut chewing and atrial fibrillation (AF) is lacking. Thus, a nationwide ecological study was conducted to investigate this. METHODS: Two national datasets, the nationwide population-based 2005 Taiwan National Health Insurance Research dataset (NHIRD) and the 2005 National Health Interview Survey (NHIS), were used for analyses. The clinical characteristics, inhabited area and medical histories for 375,360 eligible males were retrieved from the 2005 NHIRD. Health related behaviors including areca nut chewing, cigarette smoking, infrequent vegetable eating, and exercise habit were collected from the 2005 NHIS. The prevalence of AF and the areca nut chewing rate were evaluated by multivariate analysis. RESULTS: Of the 375,360 males (mean age, 44 years old), 1,326 (0.35%) were diagnosed with AF. The higher areca nut chewing rate, the higher prevalence rate of AF in Taiwan (Spearman correlation coefficient r=0.558, p=0.007). After adjusting for other covariates, the current areca nut chewing rate was found to be independently associated with the prevalence of AF. The adjusted odd ratio for areca nut chewing was 1.02 (95% CI=1.00-1.04) in risk of AF prevalence. CONCLUSIONS: Areca nut chewing is independently associated with the prevalence of AF in Taiwanese men. However, further exploration of the underlying mechanisms is necessary.
