CANCER AND ACTIVITY OF HISPANICS IN ARIZONA AND MEXICO

结肠癌的死亡率比美国高出四到五倍， 美国对比墨西哥 墨西哥人的结肠癌发病率- 生活在美国的美国人开始反思 U.S.pattern. 体力活动与结肠风险有关 癌 大规模流行病学研究 西班牙裔的活动和癌症之间的联系， 直到一个简单的文化敏感的工具被设计出来。 是 本研究项目的目的是开发这样一种工具。 仪器 将设计和测试与成年墨西哥裔美国人生活在 图森和成年墨西哥人生活在北方索诺拉，墨西哥社区。 以下方法将用于设计和测试活动 问卷 首先，运用人类学的观察方法， 访谈和焦点小组，设计一个文化敏感的身体 活动问卷（PAQ）。 第二，测试可靠性或 PAQ的可重复性，通过将问卷管理到 相同的受访者在一个月的时间间隔三次，并比较 结果 第三，验证PAQ用于估计平均每日能量 将PAQ结果与能源支出估计值进行比较， 使用心率方法计算。

Mortality rates for colon cancer are four to five times higher in the United States compared to Mexico. The rate of colon cancer in Mexican- Americans living in the United States is beginning to reflect the U.S.pattern. Physical activity has been linked with risk for colon cancer. Large scale epidemiological research into the relationship between activity and cancer in Hispanics cannot easily be conducted until a simple culturally sensitive tool has been designed. It is the purpose of this research project to develop such a tool. The instrument will be designed and tested with adult Mexican-Americans living in Tucson and adult Mexicans living in a northern Sonora, Mexico community. The following methods will be used to design and test the activity questionnaire. First, using anthropological methods of observation, interviews, and focus groups, design a culturally-sensitive physical activity questionnaire (PAQ). Second, test the reliability or reproducibility of the PAQ by administering the questionnaire to the same respondents three times at one month intervals and compare the results. Third, validate the PAQ for estimation of average daily energy expenditure by comparing PAQ results to energy expenditure estimates calculated using the heartrate method.
