A longitudinal study of dietary inflammatory index and quality of life in people with osteoarthritis: data from the Osteoarthritis Initiative database.

ABSTRACT: Dietary inflammatory index (DII) was demonstrated to be correlated to quality of life (QoL) in people with osteoarthritis (OA), but there is lack of an exploration of the relationship between the longitudinal trajectories of QoL and DII in OA people. This study aims to investigate the relationship between DII and longitudinal trajectories of QoL, and the moderating effect of physical activity on this relationship in OA people. Data from the Osteoarthritis Initiative database includes baseline measurements and follow-up data at 1, 2, 3, 4, 5, 6, and 8-year intervals for the 12-item Short-Form Health Outcome Survey questionnaire (physical and mental dimensions) and baseline sociodemographic characteristics utilized in this study. Dual Group-Based Trajectory Modeling analysis was employed to
