Abstract

OBJECTIVES

Body image and eating disturbances have become global phenomena, yet prospective designs have rarely been employed in research on non-Western samples. This study tested the extent to which select features of the dual-pathway account of bulimic disturbances contributed to changes in eating disorder symptoms reported among adolescents from China.

METHODS

A sample of 593 Chinese middle school and high school students (217 boys, 376 girls) completed measures of eating disorder symptoms, body image concerns, internalized physical appearance ideals, negative affect, and appearance-based social pressure, teasing, and comparison and returned 9 months later to complete the same measures.

RESULTS

For both girls and boys, increases in eating disorder symptoms between Times 1 and 2 were predicted by higher baseline levels of fatness concern and perceived social pressure. Among the girls, negative affect also contributed marginally to changes in eating disorder symptoms.

CONCLUSIONS

Findings suggest specific risk factors including personal concerns about being fat and negative social feedback about physical appearance, may help to explain changes in eating disturbances of adolescents over time and across specific cultures.

摘要

目标

身体意象和饮食失调已成为全球现象,但前瞻性设计在非西方样本研究中很少被采用。本研究检验了暴食症紊乱双路径模型的特定特征在多大程度上导致了中国青少年饮食失调症状的变化。

方法

593名中国中学生(217名男生,376名女生)完成了饮食失调症状、身体意象担忧、内化的外貌理想、消极情绪以及基于外貌的社会压力、取笑和比较的测量,并在9个月后再次完成相同测量。

结果

对于女孩和男孩,第1次到第2次饮食失调症状的增加可由更高的基线肥胖担忧水平和感知到的社会压力预测。在女孩中,消极情绪对饮食失调症状的变化也有轻微影响。

结论

研究结果表明,包括个人对肥胖的担忧和关于外貌的负面社会反馈等特定风险因素,可能有助于解释青少年饮食失调随时间推移和跨特定文化的变化。
