whites.Most studies in the United Kingdom and the United States report a higher prevalence and lower awareness of hypertension in black people than in white people.In Mexican-Americans,the prevalence and incidence of hypertension is similar to or lower than in whites.NHANES III reported an age-adjusted prevalence of hypertension at 20.6%in Mexican-Americans and 23.3%in non-Hispanic whites.Group

Disease and Stroke Statistics 2007Hypertension Prevalence by Ethnic/Minority GroupsContributing Factors:Social,Environmental,or Genetic?Environmental factors ultimately related to race(e.g.socioeconomic disadvantage,less access to health care)play roles in causing and sustaining hypertension 1,2 Despite similar African heritage,Africans living in Africa or West Indies have much less hypertension than African Americans 3,4 In rural Africa,hypertension prevalence is very low and blood pressure does not rise with age as it does in all ethnic groups in US 31 Cooper RS,Rotimi

IndicationsNot at Goal BPOptimize dosages or add drugs until goal BP is achieved.Consider hypertension specialist consult.Chobanian AV,et al.JAMA.2003;289:2560-2572.ACEI=ACE inhibitorCCB=calcium
