Little is known about the long-term physical consequences of bulimia nervosa. Some physical morbidity may result from high rates of cigarette smoking. The aim of the present study was to test three hypotheses regarding smoking among women with bulimia nervosa.
The subjects were 102 women with DSM-IV bulimia nervosa, 204 matched normal controls, and 102 matched controls with affective or anxiety disorders. All three groups were recruited from the same community sample. Interview measures were used for diagnosis and for information on smoking.
A higher proportion of the bulimia nervosa cases were smokers than of either comparison group. Of those smokers who had achieved a period of abstinence, bulimia nervosa cases were more likely than normal control subjects to have resumed smoking, and more likely to attribute their resumption to concern about their weight.
Smoking-related morbidity should be assessed in long-term follow-up studies of bulimia nervosa.
关于神经性贪食症的长期身体后果，人们所知甚少。吸烟率高可能会导致一些身体疾病。本研究的目的是检验关于神经性贪食症女性吸烟情况的三个假设。
研究对象包括102名符合《精神疾病诊断与统计手册》第四版（DSM-IV）标准的神经性贪食症女性、204名匹配的正常对照者以及102名匹配的情感或焦虑障碍对照者。所有三组均从同一社区样本中招募。采用访谈措施进行诊断并获取吸烟相关信息。
神经性贪食症患者中吸烟者的比例高于两个对照组。在那些曾有过一段时间戒烟的吸烟者中，神经性贪食症患者比正常对照者更有可能重新开始吸烟，且更有可能将重新吸烟归因于对体重的担忧。
在神经性贪食症的长期随访研究中，应评估与吸烟相关的发病率。
