Comparison of Gender Differences in Intracerebral Hemorrhage in a Multi-Ethnic Asian Population.

ABSTRACT: Intracerebral hemorrhage (ICH) accounts for 10-15% of all first time strokes and with incidence twice as high in the Asian compared to Western population. This study aims to investigate gender differences in ICH patient outcomes in a multi-ethnic Asian population.Data for 1,192 patients admitted for ICH were collected over a four-year period. Multivariate logistic regression was used to identify independent predictors and odds ratios were computed for 30-day mortality and Glasgow Outcome Scale (GOS) comparing males and females.Males suffered ICH at a younger age than females (62.2 ± 13.2 years vs. 66.3 ± 15.3 years; P<0.001). The occurrence of ICH was higher among males than females at all ages until 80 years old, beyond which the trend was reversed. Females exhibited increased severity on admission as measured by Glasgow Coma Scale compared to males (10.9 ± 4.03 vs. 11.4 ± 4.04; P = 0.030). No difference was found in 30-day mortality between females and males (F: 30.5% [155/508] vs. M: 27.0% [186/688]), with unadjusted and adjusted odds ratio (F/M) of 1.19 (P = 0.188) and 1.21 (P = 0.300). At discharge, there was a non-statistically significant but potentially clinically relevant morbidity difference between the genders as measured by GOS (dichotomized GOS of 4-5: F: 23.7% [119/503] vs. M: 28.7% [194/677]), with unadjusted and adjusted odds ratio (F/M) of 0.77 (P = 0.055) and 0.87 (P = 0.434).In our multi-ethnic Asian population, males developed ICH at a younger age and were more susceptible to ICH than women at all ages other than the beyond 80-year old age group. In contrast to the Western population, neurological status of female ICH patients at admission was poorer and their 30-day mortality was not reduced. Although the study was not powered to detect significance, female showed a trend toward worse 30-day morbidity at discharge.

Project description:BackgroundIntracerebral hemorrhage (ICH) is associated with an increased risk of ischemic stroke. Whether there are racial and ethnic disparities in the risk of ischemic stroke after ICH is poorly understood. We therefore aimed to test the hypothesis that non-Hispanic Black and Hispanic ICH patients have a higher risk of ischemic stroke compared with non-Hispanic White ICH patients.MethodsWe performed a retrospective cohort study using the Healthcare Cost and Utilization Project (HCUP) on all hospitalizations at all nonfederal hospitals in Florida from 2005 to 2018 and New York from 2006 to 2016. Race and ethnicity were coded as a single variable in HCUP. We included patients with an ICH, and without a prior or concomitant diagnosis of ischemic stroke, ascertained using validated International Classification of Diseases-Clinical Modification-9 and 10 diagnosis codes. Using Cox proportional hazard models, we studied the relationship between race and risk of ischemic stroke starting from the time of discharge from ICH hospitalization, after adjustment of demographics and vascular comorbidities.ResultsWe included 91 342 patients with ICH-62% non-Hispanic White, 18% non-Hispanic Black, and 12% Hispanic patients. Non-Hispanic Black and Hispanic patients were younger and had a higher prevalence of cardiovascular comorbidities; however, atrial fibrillation was more prevalent among non-Hispanic White patients. During a median follow-up period of 4.4 years (interquartile range, 1.5-8.1), an incident ischemic stroke occurred in 3377 (6%) non-Hispanic White, 1323 (8%) non-Hispanic Black, and 844 (8%) Hispanic patients. In adjusted Cox models, the risk of an ischemic stroke was significantly higher among non-Hispanic Black patients (hazard ratio, 1.6 [95% CI, 1.5-1.8]) and Hispanic patients (hazard ratio, 1.4 [95% CI, 1.3-1.5]), compared with non-Hispanic White patients. Similar results were obtained in sensitivity analyses when using death as a competing risk and after excluding patients with atrial fibrillation and valvular heart disease.ConclusionsIn a large heterogeneous cohort of patients with ICH, we found that non-Hispanic Black and Hispanic patients had a significantly higher risk of ischemic stroke compared with non-Hispanic White patients.

Project description:INTRODUCTION: The prevalence of metabolic syndrome is increasing disproportionately among the different ethnicities in Asia compared to the rest of the world. This study aims to determine the differences in the prevalence of metabolic syndrome across ethnicities in Malaysia, a multi-ethnic country. METHODS: In 2004, we conducted a national cross-sectional population-based study using a stratified two-stage cluster sampling design (N?=?17,211). Metabolic syndrome was defined according to the International Diabetes Federation/National Heart, Lung and Blood Institute/American Heart Association (IDF/NHLBI/AHA-2009) criteria. Multivariate models were used to study the independent association between ethnicity and the prevalence of the metabolic syndrome. RESULTS: The overall mean age was 36.9 years, and 50.0% participants were female. The ethnic distribution was 57.0% Malay, 28.5% Chinese, 8.9% Indian and 5.0% Indigenous Sarawakians. The overall prevalence of the metabolic syndrome was 27.5%, with a prevalence of central obesity, raised triglycerides, low high density lipoprotein cholesterol, raised blood pressure and raised fasting glucose of 36.9%, 29.3%, 37.2%, 38.0% and 29.1%, respectively. Among those <40 years, the adjusted prevalence ratios for metabolic syndrome for ethnic Chinese, Indians, and Indigenous Sarawakians compared to ethnic Malay were 0.81 (95% CI 0.67 to 0.96), 1.42 (95% CI 1.19 to 1.69) and 1.37 (95% CI 1.08 to 1.73), respectively. Among those aged ?40 years, the corresponding prevalence ratios were 0.86 (95% CI 0.79 to 0.92), 1.25 (95% CI 1.15 to 1.36), and 0.94 (95% CI 0.80, 1.11). The P-value for the interaction of ethnicity by age was 0.001. CONCLUSIONS: The overall prevalence of metabolic syndrome in Malaysia was high, with marked differences across ethnicities. Ethnic Chinese had the lowest prevalence of metabolic syndrome, while ethnic Indians had the highest. Indigenous Sarawakians showed a marked increase in metabolic syndrome at young ages.
