ABSTRACT=BackgroundWeight stigma is linked to a range of adverse outcomes, including reduced engagement in physical activity, yet the psychological pathways underlying these associations remain insufficiently understood. This study examined the relationship between weight stigma and motivation to avoid exercise, with a particular focus on the mediating roles of internalized weight stigma and social anxiety.MethodsA total of 1,397 Chinese university students (aged 17–25) were recruited via the online survey platform Sojump. Participants completed validated questionnaires assessing weight stigma, exercise avoidance motivation, internalized weight stigma, and social anxiety. Structural equation modeling was employed to evaluate the hypothesized relationships. The study protocol was approved by the Ethics Committee of the College of Physical Education, Southwest University.ResultsCorrelational analyses suggested a partial mediation model, in which weight stigma contributed to exercise avoidance motivation both directly and indirectly via internalized weight stigma and social anxiety. Specifically, higher weight stigma was linked to greater internalized weight stigma (β = 0.45, p < 0.001), which, in turn, was associated with increased social anxiety (β = 0.40, p < 0.001), ultimately leading to heightened motivation to avoid exercise (β = 0.33, p < 0.001).LimitationsThe limitations of this study include the use of a cross-sectional design, which precludes causal inferences, and the relatively small number of individuals with a high BMI in the sample, which may limit the broader applicability and generalizability of the findings.ConclusionWe recommend that interventions focus on reducing internalized weight stigma and social anxiety to help individuals overcome exercise avoidance motivation, thereby promoting physical activity and improving mental health.
