Body image flexibility has shown robust negative associations with body dissatisfaction. However, research in this area is confined to cross-sectional studies on adults in Western cultural contexts. Responding to these gaps and the unique cultural nuances and increasing prevalence estimates of body dissatisfaction in China, we examined the bi-directional nature of body image flexibility and body fat and muscularity dissatisfaction in Chinese adolescent boys and girls (N = 1381, 57.3 % girls) at two points over 18 months (Wave [W] 1=baseline, W2=18 months later). We also explored sex differences in longitudinal models. In boys, higher W1 body image flexibility was associated with lower W2 body fat dissatisfaction, and higher W1 body fat dissatisfaction was associated with lower W2 body image flexibility. Null prospective associations between body image flexibility and muscularity dissatisfaction were identified in boys. In girls, higher W1 body fat and muscularity body dissatisfaction were associated with lower W2 body image flexibility. Higher W1 body image flexibility was associated with lower W2 body fat and muscularity dissatisfaction in girls. We found no significant sex differences in the models. Findings advance a multicultural understanding of the temporal and bi-directional links between body image flexibility and body fat and muscularity dissatisfaction in Chinese adolescents.
身体意象灵活性已显示出与身体不满存在强烈的负相关。然而，该领域的研究仅限于对西方文化背景下成年人的横断面研究。鉴于这些差距以及中国独特的文化细微差别和身体不满患病率估计值的上升，我们在18个月内的两个时间点，对中国青少年男孩和女孩（N = 1381，57.3%为女孩）的身体意象灵活性与体脂及肌肉不满意之间的双向关系进行了研究（第1波[W]1 = 基线，W2 = 18个月后）。我们还探讨了纵向模型中的性别差异。在男孩中，较高的W1身体意象灵活性与较低的W2体脂不满意相关，而较高的W1体脂不满意与较低的W2身体意象灵活性相关。在男孩中，未发现身体意象灵活性与肌肉不满意之间存在前瞻性关联。在女孩中，较高的W1体脂和肌肉身体不满意与较低的W2身体意象灵活性相关。较高的W1身体意象灵活性与女孩较低的W2体脂和肌肉不满意相关。我们发现模型中没有显著的性别差异。研究结果促进了对中国青少年身体意象灵活性与体脂及肌肉不满意之间的时间和双向联系的多元文化理解。
