Objective:
To assess the prevalence of nutritional risk factors present in the Geisinger Rural Aging Study (GRAS) cohort and to determine the impact of nutritional risk factors on health outcomes.

Approach:
Validate a previously developed GRAS Population specific food frequency questionnaire (PSFFQ) issued to a subset of the GRAS cohort by comparison with selected anthropometric and laboratory indicators. Administer the validated and revised PSFFQ to a larger sample of the full GRAS cohort and capture nutritional status (including obesity), functional, life quality, health care resource use, and morbidity and mortality outcomes as the cohort ages in place. Confirm PSFFQ validation through analysis of the larger cohort sample.
