BACKGROUND: Cancer is becoming a significant health problem for American Indians and Alaska Natives. Despite the precipitous increase in cancer rates in these populations, limited data are available regarding the extent of cancer control services available in these communities. METHODS: A cross-sectional survey of tribal health directors of all federally recognized tribes was undertaken to discover the breadth of cancer control activities offered and directors' perceptions of and priorities ascribed to cancer. RESULTS: Little more than half (53%) of respondents perceived cancer rates to be increasing. Cancer was found to rank fifth among seven health conditions when directors were asked to rank their tribe's commitment to confronting each. Lower relative levels of awareness of cancer patterns coupled with competing health problems relegated cancer control activities to low-priority issues. CONCLUSIONS: Findings from this study underscore the need to elevate the issue of cancer in Indian Country and to educate investigators to become more sensitive and responsive to other tribal health issues.
BACKGROUND: More than a third of all cancers in the United States are thought to be attributable to various nutritional factors, and major changes in nutrition have been experienced by American Indians and Alaska Natives in the past century. METHODS: The published literature was reviewed to summarize the relationship between diet and cancer, to summarize what is known about the past and current diet of American Indians and Alaska Natives, and to consider whether nutrition might play a role in their current or future risk of cancer. RESULTS: Epidemiologic studies show a consistent pattern of lower risk for cancers of the colon and lung among those who eat larger amounts of fruits and vegetables and higher risk for cancers of the colon and prostate for those who eat larger amounts of fat. Limited data indicate that the diets of American Indians and Alaska natives are similar to the current average American diet, that is, high in fat and low in fruits and vegetables. CONCLUSIONS: Diet is an important factor for several major cancers. Although the cancer rates among many Native American groups are currently lower than among non-native Americans, they seem to be increasing. Cancer rates among Native Alaskans are already much higher than for non-native Americans. Nutrition-related cancers are likely to increase in the future among Native Americans as a result of past changes in diet. However, Native Americans may have a stronger cultural basis than do non-native Americans to adopt traditional principles of the value of good foods and physical activity to achieve future nutritional improvements to reduce cancer risk.
