RRSS Improving SES Data: Linkage w State Vital Records, Birth Certificate Data

许多研究已经观察到，较低的社会经济地位（SES）与某些部位的癌症发病风险增加和大多数癌症部位的生存率降低有关。然而，社会经济地位的影响的证据是有限的，因为社会经济地位往往是在总量或区域一级衡量的（例如，一个邮政编码或人口普查区的平均家庭收入，一个街区组的贫困人口比例）。大加州癌症登记处（CRGC）的研究人员建议实施由犹他州癌症登记处（UCR）的研究人员制定的一项策略，该策略允许通过将癌症病例与州出生证明记录联系起来，在个人水平上直接测量SES。CRGC的研究人员与UCR合作，利用加州生命统计办公室的数据，评估将犹他州的联系方法应用于1997年至2009年加州出生率的可行性。此外，将从加州癌症登记处（CCR）中确定1997年期间或之后出生的儿童癌症病例，并将这些病例与出生记录进行匹配。从这个链接的文件，SES将确定使用父母的职业和行业，以确定每个案件SES在出生时。使用队列和病例对照方法，研究SES对儿童癌症的影响。将结果与犹他州的可比儿科人群进行比较和对比。这些数据还将与基于普查的措施进行比较，以确定可比性。这项研究可能会提供一个更好的了解健康和癌症的SES方面的差距，并提供了一种方法，为其他癌症登记遵循。 与犹他州癌症登记处（UCR）合作，他们制定的一项战略将得到实施，该战略允许通过将癌症登记病例与州出生证明记录联系起来，在个人层面直接测量SES。人们有兴趣更好地了解SES方面的健康和癌症差异，这是国家癌症研究所（NCI）战略计划的主要重点。

Numerous studies have observed that lower socioeconomic status (SES) is associated with increased risk of incident cancer for some sites and reduced survival for most cancer sites. However, evidence of the impact of SES is limited because SES is often measured at an aggregate or area level (e.g., mean household income for a zip code or census tract, proportion poor in a block group). Investigators at the Cancer Registry of Greater California (CRGC) propose to implement a strategy developed by investigators at the Utah Cancer Registry (UCR) that permits a direct measurement of SES at the individual level through record linkage of cancer cases to state birth certificate records. In collaboration with UCR, investigators at the CRGC propose to assess the feasibility of applying Utah¿s linkage methodologies to California births from 1997 to 2009, using data from the California Office of Vital Statistics. In addition, pediatric cancer cases born during or after 1997 will be identified from the California Cancer Registry (CCR) and these cases will be matched against the birth records. From this linked file, SES will be determined using the parent¿s occupation and industry to determine each cases SES at birth. Using cohort and case-control methods, the effect of SES on pediatric cancers will be studied. Results will be compared and contrasted with the comparable pediatric population in Utah. These data will also be compared to census based measures to determine comparability. This research may provide a better understanding of health and cancer disparities in terms of SES and provide a methodology for other cancer registries to follow. In collaboration with the Utah Cancer Registry (UCR), a strategy they developed will be implemented that permits a direct measurement of SES at the individual level through linking cancer registry cases to state birth certificate records. There is interest in obtaining a better understanding health and cancer disparities in terms of SES, which is a major focus of the National Cancer Institute¿s (NCI) strategic plan.
