Researchers analyzed data from 421 older adults in Southern California, looking at dietary patterns, physical activity, sleep, smoking, alcohol use, and other lifestyle factors.
What the researchers found
Participants with the highest Healthy Lifestyle Index scores had substantially greater odds of reporting better quality of life and better self-rated health than participants with the lowest scores. The results showed a strong dose-response relationship, with progressively healthier lifestyle scores associated with progressively better reported health.
Among participants who had followed their dietary pattern for at least 10 years, a vegetarian diet was also associated with better self-rated health.
Why this research matters
The findings highlight the potential importance of an overall healthy lifestyle in later life. Rather than focusing on a single behavior, the study suggests that multiple health-promoting habits maintained over time are strongly associated with how older adults perceive their health and quality of life.
Because this was a cross-sectional study, the findings show associations and do not establish that these lifestyle behaviors caused the differences observed.
