Cardiovascular disease (CVD) is the leading cause of death among American Indians and Alaska Natives and varies considerably by tribe and region. The Inter-Tribal Heart Project (ITHP) was designed to determine the prevalence of CVD risk factors in two Chippewa tribes and one Menominee tribe because of their high CVD mortality rates. A random sample of 1370 individuals 25 and older participated in ITHP. The prevalence of hypertension (systolic blood pressure (SBP)=140mmHg and/or diastolic blood pressure (DBP)=90mmHg and/or currently taking antihypertensive medications) was 31% (men=38%, women=27%). Approximately 75% (men=74%, women=76%) of hypertensives reported being told by a health professional that they have hypertension (awareness). Among hypertensives, 59% (men=55%, women=62%) reported currently using antihypertensive medications (treated). Twenty-eight percent (men=22%, women=32%) had their blood pressure under control (SBP<140mmHg and DBP<90mmHg). The prevalence of hypertension among those with diabetes was significantly higher than those with normal glucose tolerance (54% versus 23%, p=0.001). Moreover, 60% of participants with diabetes had blood pressure values in excess of the treatment goal of £ 130/85. The high prevalence of hypertension and low prevalence of control suggests that programs that target prevention and control are urgently needed. These programs should include pharmacologic and non-pharmacologic approaches and culturally appropriate programs that incorporate beliefs about hypertension causation, manifestations and treatment among American Indians in an attempt to reduce their burden of hypertension.
Learning Objectives: At the conclusion of the session, the participant will be able to describe the prevalence of hypertension awareness, treatment and control among American Indians
