Does body mass index affect mortality in middle-aged Korean men?
Both high and low body mass index are associated with increased mortality in middle-aged Korean men, demonstrating U-shaped or J-shaped relationships depending on the cause of death.
No takes yet. Share an insight, caveat, or question.
May inform risk stratification in Korean men; leaves open causality and generalizability pending prospective data.
Song et al. (2001) conducted a cohort in Mortality (n=235,398). Body mass index was evaluated on All-cause and cause-specific mortality. Both high and low body mass index were related to increased mortality among Korean men, demonstrating a U-shaped relationship with all-cause mortality over a 12-year follow-up.
