The purpose of this study was to compare the frequency and types of anogenital trauma in rape victims as a function of the time interval between the assault and recent (72 h) consensual sexual intercourse.
This retrospective cohort trial evaluated consecutive female patients, age 13 years or older, presenting to a community-based nurse examiner clinic (NEC) during a 5-year study period. The NEC facility is staffed by forensic nurses trained to perform medical-legal examinations using colposcopy with nuclear staining and digital imaging. Eligible patients were classified into five different groups based on the time interval from the last consensual intercourse to the forensic examination (none, 0-24 h, 25-48 h, 49-72 h, 73-96 h). Patient demographics, assault characteristics, and injury patterns were recorded using a standardized classification system.
A total of 947 cases of sexual assault met the inclusion criteria and were divided into five groups. The age range was 13 to 87 years (mean, 23.9 years); 78% were examined within 24 h following sexual assault. The five study groups were comparable in terms of demographics, assault history, and incidence of non-genital injuries. The overall frequency, type, or location of anogenital injury did not vary significantly between groups (p > 0.5).
This is the first clinical study to systematically compare the prevalence and typology of anogenital injuries in sexual assault victims who have had consensual intercourse within four days before a forensic exam. The frequency, type or location of anogenital trauma did not vary significantly based on the time interval from last consensual intercourse to the forensic examination.
本研究旨在比较强奸受害者的会阴部创伤的频率和类型，这些受害者的最近一次（72 小时内）自愿性行为与强奸之间的时间间隔。
本回顾性队列研究评估了在 5 年研究期间连续出现于社区性侵害护士检查诊所（NEC）的女性患者，年龄 13 岁及以上。NEC 设施配备了经过培训的法医护士，他们使用阴道镜检查和核染色以及数字成像来进行法医检查。根据最近一次自愿性行为到法医检查的时间间隔，将符合条件的患者分为五个不同的组（无、0-24 小时、25-48 小时、49-72 小时、73-96 小时）。使用标准化分类系统记录患者的人口统计学、攻击特征和损伤模式。
共有 947 例性侵犯符合纳入标准，并分为五组。年龄范围为 13 至 87 岁（平均 23.9 岁）；78%的患者在性侵犯后 24 小时内接受检查。五个研究组在人口统计学、攻击史和非生殖器损伤的发生率方面具有可比性。各组之间的会阴部损伤的总体频率、类型或位置没有显著差异（p>0.5）。
这是第一项系统比较在法医检查前四天内有过自愿性行为的性侵犯受害者的会阴部损伤的发生率、类型和位置的临床研究。从最近一次自愿性行为到法医检查的时间间隔，不会显著影响会阴部创伤的频率、类型或位置。
