A higher incidence of spontaneous intracerebral and subarachnoid hemorrhage among Hispanics than non-Hispanic whites has been measured in Bernalillo County, New Mexico. In an attempt to explain these differences, we compared historical vascular risk factors between Hispanics and non-Hispanic whites living in this community.
An ongoing telephone survey, the Behavioral Risk Factor Surveillance System, collected annual data about vascular risk factors among non-institutionalized, randomly selected adults. Data covering 6 years, 1988-1993, were analyzed.
There were 843 Hispanic and 1,635 non-Hispanic white residents of Bernalillo County, New Mexico, who participated in this survey. Because Hispanics were significantly younger than non-Hispanic whites (37.7 vs. 43.4 years, p < 0.001), all other comparisons were adjusted for age. Prevalence of hypertension was similar between these ethnic groups (15-17%). Prevalence of alcohol drinking considered risky for abuse was similar between these ethnic groups (5-6%), but was significantly higher among Hispanic men than women (8.5 vs. 1.6%, p < 0.001). The quantity of alcohol consumption among those at risk for abuse was similar between these ethnic groups. Prevalence of current cigarette smoking was similar between these ethnic groups (22-23%), but Hispanics smoked significantly less than non-Hispanic whites (11.4 vs. 15.2 cigarettes per day, p < 0.001) and among non-Hispanic whites, men smoked significantly more than women (17.0 vs. 13.4 cigarettes per day, p = 0.001).
The vascular risk factors which we compared between Hispanics and non-Hispanic whites do not help to explain the higher incidence of hemorrhagic strokes among the Hispanics in Bernalillo County, New Mexico. Additional risk factors for hemorrhagic strokes in these two ethnic groups should be studied.
在新墨西哥州的伯纳利欧县，已检测出西班牙裔人群自发性脑出血和蛛网膜下腔出血的发病率高于非西班牙裔白人。为解释这些差异，我们比较了居住在该社区的西班牙裔和非西班牙裔白人之间的既往血管危险因素。
一项正在进行的电话调查，即行为危险因素监测系统，收集了非住院、随机选取的成年人中有关血管危险因素的年度数据。分析了1988年至1993年这6年的数据。
新墨西哥州伯纳利欧县有843名西班牙裔居民和1635名非西班牙裔白人居民参与了这项调查。由于西班牙裔居民明显比非西班牙裔白人年轻（37.7岁对43.4岁，p<0.001），所有其他比较均针对年龄进行了调整。这些种族群体之间高血压患病率相似（15%-17%）。被认为有滥用风险的饮酒患病率在这些种族群体之间相似（5%-6%），但西班牙裔男性中的患病率显著高于女性（8.5%对1.6%，p<0.001）。有滥用风险者的酒精消费量在这些种族群体之间相似。当前吸烟率在这些种族群体之间相似（22%-23%），但西班牙裔吸烟者明显少于非西班牙裔白人（每天11.4支对15.2支，p<0.001），在非西班牙裔白人中，男性吸烟明显多于女性（每天17.0支对13.4支，p=0.001）。
我们在西班牙裔和非西班牙裔白人之间比较的血管危险因素无助于解释新墨西哥州伯纳利欧县西班牙裔人群出血性中风发病率较高的现象。应研究这两个种族群体出血性中风的其他危险因素。
