Association of Changes in Diet Quality with Total and Cause-Specific Mortality.

ABSTRACT:

Background

Few studies have evaluated the relationship between changes in diet quality over time and the risk of death.

We used Cox proportional-hazards models to calculate adjusted hazard ratios for total and cause-specific mortality among 47,994 women in the Nurses' Health Study and 25,745 men in the Health Professionals Follow-up Study from 1998 through 2010.

Results

The pooled hazard ratios for all-cause mortality among participants who had the greatest improvement in diet quality (13 to 33% improvement), as comp
