Purpose: This study was done to identify the relationships among diabetic health leader attitude, diabetic knowledge, and health conservation in highly educated elders. Methods: The participants were 119 elders aged 65 or more who were attending the senior welfare centers in D and K City and had at least a high school degree. Data were collected from June 10 to July 7 in 2013. Data analysis included one-way ANOVA, independent t-test, Pearson’s correlation, and stepwise multiple regression, done with the SPSS/WIN 19.0 program. Results: A positive correlation was found among diabetic health leader attitude, diabetic knowledge, and health conservation. Health conservation explained 26% (β=.31) and diabetic knowledge explained 2% (β=.18) of the variance in diabetic health leader attitude. Conclusion: The results indicate that to increase diabetic health leader attitude among highly educated elders, health leader programs are needed for increasing their diabetic knowledge and health conservation.
