Adoption of a healthy lifestyle can slow physical decline and improve well being of the elderly. The purpose of this study was to examine the relationship of six aspects of a healthy lifestyle (nutrition, exercise, stress management, self actualization, health responsibility, and interpersonal support) with selected demographic variables, perceived health status, and health locus of control in the well elderly. The sample consisted of 297 volunteers. Pearson product-moment correlations and stepwise multiple regression procedures revealed that perceived health status and health locus of control were significant predictors of healthy lifestyles. Demographic variables, posited as modifying factors, were found to be associated with perceived health and locus of control but were not predictive of lifestyle practices.
