title: A longitudinal assessment of the impact of health/fitness status and health behavior on perceived quality of life.
abstract: This study extended cross-sectional research associating quality of life with health and fitness factors. Longitudinal analyses were performed on data collected from 519 U.S. Navy personnel to assess changes in quality of life with changes in health/fitness status and health behavior dimensions at 1-yr. and 2-yr. intervals. Multiple regression results showed that such changes were positively associated with changes in health/fitness status and behaviors related to accident control and wellness maintenance, with these predictors accounting for 8% of the variance in change in quality of life at the 1-yr. interval. At the 2-yr. interval, such change was associated with health/fitness status and accident control behaviors, accounting for 11% of the variance. Health behavior change made a unique contribution to change in quality of life after controlling for changes in health/fitness status at both intervals. Findings affirm modest yet consistent associations between changes in fitness and health variables and quality of life and suggest that improvements in health behavior influence quality of life independently of one's health/fitness status.
