Title:

A Genome-Wide Scan for Quantitative Trait Loci of Hematocrit - A Framingham Study

Number:

03-H-0219

Summary:

Since 1948, residents of Framingham, Massachusetts, have participated in a program that collects blood samples and clinical data to provide a rare and valuable database for scientific research.

The purpose of this study is to support this national resource by aiding in its research capacity. Specifically, researchers in this study will (1) investigate heart, lung, and blood diseases; stroke; memory loss; joint disease; bone loss; deafness; cancer; blood vessel diseases and other health conditions, and (2) examine DNA and its relationship to risk of developing these disease and health conditions.

Approximately 330 families have participated in the Framingham Study. Participants will be required to undergo a four-hour exam and to take that exam every two years thereafter. During the exam, the Framingham investigators will (1) interview participants about medical status, health issues, and lifestyles; (2) perform a regular physical exam; (3) obtain blood and urine samples and administer a glucose-tolerance test; (4) supervise a brisk six-minute treadmill walk; (5) administer an ultrasound procedure; and (6) review and obtain copies of medical and hospital records. Participants will also be asked to complete a questionnaire at home regarding dietary and health habits.
