The aim of this
study is to clarify factors related to premature death among Japanese professional
baseball players by a case-control analysis. The subjects are two matching
groups of 622 Japan Professional Baseball (JPB) league players, those deceased
and those surviving. Cases and controls are matched by birth year. All players
debuted on the first string between 1934 and 2003, and are listed in The
Official Baseball Encyclopedia of Japan. To compare means and frequencies of
characteristics between deceased and surviving groups, t-tests and chi-square
tests were used. A logistic regression analysis was assessed contributions of
each independent variable on death. Significant differences between deceased
and surviving players were observed in this study; deceased players had
higher body mass indexes and longer careers. Furthermore, logistic regression
analysis confirmed that body mass index and career length were statistically significant determinants of death for baseball players. This is the first report to
examine factors of death for professional baseball players except employing data attained from Major League Baseball.
