본 연구는 성범죄를 저지른 변태성욕장애 환자들의 임상적 특징을 알아보고 소아성애장애의 혈중 테스토스테론 농도와 지적장애 동반 유무에 대해 알아본 국내 첫 연구로 치료감호 3호 판결을 받은 변태성욕장애 환자들 중에서 소아성애장애가 제일 많았고, 소아성애장애 환자들은 혈중 테스토스테론 농도가 낮았으며 지적장애가 많이 동반되었다. 본 연구 결과는 몇몇 제한점으로, 보다 많은 대상자를 포함하는 전향적 추적연구와 같은 추가 연구와 반복 검증이 필요할 것으로 생각되지만, 소아성애장애 환자의 특징을 이해하는 기초자료로 활용을 기대한다. 소아성범죄의 예방과 치료에 대한 적절한 임상적 활용을 위해 다양한 후속연구를 통해 소아성애장애의 병태생리를 밝히려는 노력이 지속되어야 한다.
Objectives This study compared the demographic and clinical characteristics, including blood testosterone level and intellectual capacity, between pedophilia and other types of paraphilia. Methods The medical records of 115 subjects with paraphilia who committed sex crimes and were admitted to National Forensic Hospital from January 2009 to December 2019 were analyzed retrospectively. The subjects were divided into two groups: the pedophilia group (n=59) and other paraphilia group (n=56). The demographic and clinical parameters, including intelligence quotient and blood testosterone level, were compared between the two groups. The characteristics of the sexual offenders were compared according to the age of the victims. Results Among the 115 subjects, 54 (46.9%) were diagnosed with pedophilia. The pedophilia group showed a significantly lower level of testosterone in their blood (t=-2.409, p=0.018), and higher comorbidity of intellectual disability than the paraphilia group (χ2=6.962, p=0.008). In addition, paraphilia subjects who had sexually offended victims under 18 years of age showed a higher frequency of pedophilia (67.2%, p=0.001), and a higher frequency of intellectual disability than those with adult victims (χ2=3.893, p=0.048). Conclusion In this study, pedophilia subjects showed lower blood testosterone levels and higher comorbidity of intellectual disability than those with other types of paraphilia. Further study will be needed to prevent sexual offending based on these findings.
