Multidimensional health locus of control in American Indians: the strong heart study.

OBJECTIVE Observe and record the demographic and anthropomorphic correlates of health beliefs in American Indians using the multidimensional health locus of control (MHLC) scale. DESIGN Self-administration or interview rating of Form B of the MHLC scale. SETTING Arizona, Oklahoma, and Dakota branches of The Strong Heart Study PARTICIPANTS 3665 participants (1468 men and 2197 women) aged 15 to 93 years (average 39.9) of Phase IV of The Strong Heart Study. MAIN OUTCOME MEASURES MHLC subscale scores, demographics, anthropometrics RESULTS DEMOGRAPHICS Women had higher Chance health locus of control (HLC) than men, but otherwise similar MHLC scores. Age positively correlated with lower Internal HLC and higher Powerful Others HLC. Education was associated with lower Chance HLC. MHLC scores differed by center (AZ, OK, and SD). Anthropometrics: Men with high body fat or high waist-to-hip ratio had higher Powerful Others HLC. Waist-to-hip ratio in women positively correlated to Powerful Others HLC and Chance HLC. BMI was not a strong indicator of differences in MHLC. CONCLUSIONS To our knowledge, this is the first study to examine health locus of control in American Indians. The health beliefs of American Indians in this study were similar to previous demographic studies in other populations. The associations between certain health beliefs and obesity deserve further exploration to gauge prospective risk. Clinicians should continue to identify psychological issues and counsel American Indian patients in culturally sensitive ways for improved preventive care delivery and increased efficacy of health education.
