Cancer Clinical Trial

Official title: NIH-AARP Diet and Health Secondary Research Study Based on OH95CN025 Data

Status Active, not recruiting

Clinical Trial Summary

Background:

The NIH and the American Association of Retired Persons (AARP) conducted a Diet and Health Study. It studied the links between diet, cancer, and cause of death in a group of middle-aged people in the U.S. Researchers want to learn more about how diet and lifestyle can affect cancer and mortality.

Objective:

To clarify links between diet, lifestyle, cancer, death, and chronic diseases.

Eligibility:

AARP members ages 50 to 71 who took part in study #OH95CN025 and lived in California, Florida, Pennsylvania, New Jersey, North Carolina, Louisiana, Atlanta, or Detroit in 1995 1996.

Design:

This study will use existing data and samples. Participants will not be contacted.

Participants personal data, like name, date of birth, and address, will be used. This data will be kept private. Their data and samples will get a unique ID.

Data from other follow-up studies will be used.

Cancer outcome data will be obtained from the 8 sample areas. Many participants have moved to Arizona, Nevada, and Texas. Data will be obtained from those states as well.

Cause of death and date of death will be obtained from the National Death Index.

Cheek swab samples were gathered from 2004 to 2005. They will be used to study the oral microbiome.

The University of Washington (UW) will be added as a study site. UW will study air pollution.

The process of linking with the Virtual Pooled Registry Cancer Linkage System will be explored. It uses one system. Right now, 11 state systems are used to get and link data.

Paper records will be stored in locked file rooms. Electronic data will be stored on secure servers.
