Perceived barriers to health care and health behaviours: implications for Native American elders' self-rated health.

Little is known about how Native American adults appraise their health in later life. Perceived barriers to health care and health behaviours were examined among 6813 Native elders to determine their unique associations with self-rated health (SRH). Hierarchical regression results showed inability to access needed medical care predicted poorer SRH. Statistically accounting for sociodemographics and barriers to care, health behaviours predicted SRH. The current findings suggest opportunities to improve Native elders' SRH particularly via exercise and good nutrition. In turn, enhanced SRH may lead to improved quality of life.

Body mass index and cancer screening in older American Indian and Alaska Native men.

CONTEXT: Regular screenings are important for reducing cancer morbidity and mortality. There are several barriers to receiving timely cancer screening, including overweight/obesity. No study has examined the relationship between overweight/obesity and cancer screening among American Indian/Alaska Natives (AI/ANs). PURPOSE: To describe the prevalence of fecal occult blood testing (FOBT) and prostate-specific antigen (PSA) testing among AI/AN men within the past year by age and rurality, and determine if body mass index (BMI) is associated with screening. METHODS: A national cross-sectional survey was administered face-to-face to 2,447 AI/AN men at least 55 years of age in 2004-2005. Participants were asked when they last had FOBT and PSA testing. BMI was derived from self-reported height and weight, and rurality of residence was defined by rural-urban commuting area codes. We assessed the association of cancer screening and BMI with logistic regression models, adjusting for demographic and health factors. FINDINGS: Prevalence of up-to-date FOBT and PSA testing were 23% and 40%, respectively. Older men were more likely than younger men to have FOBT and PSA testing. BMI was not associated with receipt of FOBT or PSA testing. CONCLUSIONS: This is the first study to examine obesity and health care in AI/ANs. As in other populations, FOBT and PSA testing were suboptimal. Screening was not associated with BMI. Studies of AI/AN men are needed to understand the barriers to receiving timely screenings for prostate and colorectal cancer.
