Frailty Triples Death Risk, and Exercise Alone May Not Fix It

This study suggests frailty screening in midlife may be more important than blanket exercise recommendations.
Frail adults in South Korea had over three times the mortality risk compared to robust individuals over a 16-year follow-up. Pre-frail people also had about 70% higher risk. Meeting standard exercise guidelines (150 minutes per week) didn't independently lower death risk in pre-frail or frail individuals after accounting for other factors. Frail participants who met those guidelines actually had higher healthcare costs, suggesting generic exercise advice may not suit everyone.
