CANCER AND ACTIVITY OF HISPANICS IN ARIZONA AND MEXICO

结肠癌的死亡率是美国的四到五倍 美国与墨西哥相比。墨西哥的结肠癌发病率- 生活在美国的美国人开始反映出 美国模式。体力活动与患结肠癌的风险有关 癌症。对这一关系的大规模流行病学研究 拉美裔美国人的活动和癌症之间的关系不容易进行 直到设计出一个简单的文化敏感型工具。它是 本课题研究的目的就是开发这样一个工具。这台仪器 将在成年墨西哥裔美国人中进行设计和测试 图森和居住在墨西哥索诺拉北部社区的成年墨西哥人。 将使用以下方法来设计和测试活动 问卷调查。首先，使用人类学的观察方法， 采访和焦点小组，设计一种对文化敏感的体检 活动问卷(PAQ)。第二，测试可靠性或 通过向被调查者发放调查问卷来检验PAQ的重复性 相同的受访者每隔一个月三次，并比较 结果。第三，验证用于估计平均日能量的PAQ 通过将PAQ结果与能源支出估计值进行比较来确定支出 用心电图法计算。

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.
