We examined two hypotheses regarding the potential association of pornography use with body image-related and eating disorder-related psychopathology among sexual minority males (i.e. non-heterosexual males). Our primary hypothesis was that pornography use would be associated with males' body dissatisfaction, eating disorder symptoms, thoughts about using anabolic steroids and quality of life impairment; our secondary hypothesis was that the type of pornography, namely, professional versus amateur pornography, which contains idealised and non-idealised (i.e. regular) bodies, respectively, would moderate these associations.
A sample of 2733 sexual minority males living in Australia and New Zealand completed an online survey that contained measures of pornography use, body dissatisfaction, eating disorder symptoms, thoughts about using anabolic steroids and quality of life.
Almost all (98.2%) participants reported pornography use with a median use of 5.33 hours per month. Multivariate analyses revealed that increased pornography use was associated with greater dissatisfaction with muscularity, body fat and height; greater eating disorder symptoms; more frequent thoughts about using anabolic steroids; and lower quality of life. Effect sizes for these associations were uniformly small. Neither relationship status nor genital dissatisfaction was associated with pornography use. The association between pornography use and thoughts about using anabolic steroids was stronger for viewers of professional pornography than viewers of amateur pornography.
The findings suggest that the use of pornography is weakly associated with body dissatisfaction and related variables and that the type of pornography (amateur vs professional) viewed may be a moderating factor in some cases. Within the limits of a cross-sectional study design, these findings may have implications for clinicians who treat individuals with eating disorders, body dysmorphic disorder, anabolic-androgenic steroid dependence and related concerns.
我们检验了两个假设，即性行为少数群体男性（即非异性恋男性）使用色情制品与与身体意象和饮食障碍相关的精神病理学之间的潜在关联。我们的主要假设是，色情制品的使用与男性的身体不满、饮食障碍症状、使用合成代谢类固醇的想法和生活质量受损有关；我们的次要假设是，色情制品的类型，即专业与业余色情制品，分别包含理想化和非理想化（即普通）的身体，会调节这些关联。
一个由 2733 名居住在澳大利亚和新西兰的性行为少数群体男性组成的样本完成了一项在线调查，其中包含了色情制品使用、身体不满、饮食障碍症状、使用合成代谢类固醇的想法和生活质量的测量。
几乎所有（98.2%）参与者报告使用了色情制品，中位数使用时间为每月 5.33 小时。多变量分析显示，增加色情制品的使用与更大的肌肉、体脂和身高不满；更多的饮食障碍症状；更频繁地使用合成代谢类固醇的想法；以及更低的生活质量有关。这些关联的效应大小均较小。关系状况和生殖器不满都与色情制品的使用无关。对于观看专业色情制品的人来说，色情制品的使用与使用合成代谢类固醇的想法之间的关联更强。
这些发现表明，色情制品的使用与身体不满和相关变量有微弱的关联，而且所观看的色情制品的类型（业余与专业）在某些情况下可能是一个调节因素。在横断面研究设计的限制内，这些发现可能对治疗饮食障碍、身体畸形障碍、合成代谢雄激素依赖和相关问题的个体的临床医生具有影响。
