Chinese American Cardiovascular Health Assessment-CHACHA

描述（由申请人提供）：华人是美国增长最快的移民群体之一。与生活在中国的中国人相比，生活在美国的中国人患几种慢性疾病的比例更高，包括冠心病。另一方面，他们的中风死亡率比中国人低。需要更详细地了解移民到美国后行为和生活方式的变化，以及移民对心血管疾病风险的心理社会影响，以启动干预计划，防止进一步增加华裔美国人的心血管疾病负担。虽然饮食摄入、体育活动和吸烟与心血管疾病的关系在西方国家和中国都有广泛的文献记载，但关于中国移民美国的信息却很少。具体来说，尚不清楚移民和文化适应是否以及如何改变在美华人的行为和生活方式。我们建议在纽约市华人居民中进行以社区为基础的横断面调查。在这项研究中，我们将测量行为特征，包括饮食摄入、身体活动和吸烟情况；社会心理因素，包括感知压力和社会经济地位；以及由弗雷明汉心脏项目的心血管全球风险评分（cardiovascular Global risk Score）对纽约市2000名中国参与者的心血管风险状况进行测量。虽然每个行为特征和心理社会因素对心血管风险的影响将被单独确定，但移民与文化适应、行为与生活方式、心理社会因素与心血管风险状况的总体关系将被确定

DESCRIPTION (provided by applicant): Chinese are among the fastest growing immigrant populations in the United States (US). Compared with Chinese living in China, those living in the US have higher rates of several chronic diseases, including coronary heart diseases. On the other hand, they have lower stroke mortality than those living in China. More detailed knowledge about the changes of behavior and lifestyle related to immigration to the US, as well as psychosocial impact of immigration on risk of cardiovascular disease is needed to initiate an intervention program to prevent further increasing the burden of this disease among Chinese Americans. While the associations of dietary intake, physical activity, and cigarette smoking with cardiovascular outcomes have been widely documented in both Western countries and China, little information is available about Chinese immigrants to the US. Specifically, it is not known whether and how immigration and acculturation change behavior and lifestyle among Chinese in the US. We propose a community-based cross-sectional survey among Chinese residents in New York City. In this study, we will measure behavioral characteristics, including dietary intake, physical activity and cigarette smoking; psychosocial factors, including perceived stress and socioeconomic status; as well as cardiovascular risk status measured by Cardiovascular Global Risk Score from the Framingham Heart Program for 2,000 Chinese participants in New York City. While the impact of each behavioral characteristic and psychosocial factor on cardiovascular risk will be determined separately, the overall relationship of immigration and acculturation, behavior and lifestyle, psychosocial factors and cardiovascular risk status will be evaluated interactively. The result of this study will provide necessary information for health promotion and disease prevention intervention among immigrant populations, not only for Chinese immigrants, but for other immigrants to the US as well.
