Factors that contribute to positive perceived health in an older population

This study explored the extent to which factors commonly associated with negative outcomes of aging also predicted positive perceived health in a group of community-dwelling older people. Questionnaires originally administered during a randomized trial of an HMO's outpatient group visit program supplied data from approximately 700 participants. Stepwise modeling identified significant factors within categories of predictors of perceived health. Hierarchical multiple linear regression then modeled the incremental importance of theoretically-derived categories of factors. Many but not all of the factors previously associated with negative outcomes of aging also predicted positive perceived health, accounting for 38% of the variation. The most important predictors were fewer chronic conditions and no worsening of those conditions, mobility and better physical performance status, and the absence of depression. Gender, limitations in daily living activities, dementia, and utilization of services had little effect. The categories off factors associated with positive perceived health had cumulative, interdependent effects.
