People with Anorexia Nervosa (AN) display reduced facial expression of emotions. This study investigated the expression of positive affect in response to a film, examining Duchenne and non-Duchenne smiles in 20 women who have recovered from AN (REC), 20 with acute AN and 20 healthy controls (HC). The results indicated that the REC group exhibited Duchenne and non-Duchenne smiles with higher duration and intensity than the AN group, comparable to the HC group. The findings warrant longitudinal studies to confirm that reduced expressivity is linked to acute AN, ameliorating after recovery.
神经性厌食症（AN）患者的情绪面部表达减少。本研究通过电影来观察积极情绪的表达，检查了 20 名已从 AN 中康复的女性（REC 组）、20 名患有急性 AN 的女性和 20 名健康对照组（HC 组）的 Duchenne 和非 Duchenne 微笑。结果表明，REC 组的 Duchenne 和非 Duchenne 微笑的持续时间和强度均高于 AN 组，与 HC 组相当。这些发现需要进行纵向研究来证实表情减少与急性 AN 有关，并在康复后得到改善。
