To determine the association between new sex partner acquisition and incident STDs, to describe predictors of acquiring a new sex partner, and to compare new and established sex partnerships among adolescent females.
Interview data and biological specimens for STD testing were collected from a sample of 411 adolescent females (average age 17.3 years, 44% black and 42% Hispanic) enrolled in a longitudinal study. The relationship between having a new sex partner and incident STD infection was estimated with logistic regression.
Acquisition of a new sex partner during the 12-month follow-up period was common (24%) and significantly associated with an incident STD infection (OR = 3.0, 95% CI = 1.6-5.7). Predictors of new partner acquisition were younger age, younger age at first intercourse, and alcohol or drug use before sex in past 30 days. Being in a new partnership was significantly associated with greater uncertainty about the partners' STD history and recent sex with others.
Being in a new sex partnership is an important predictor of incident STD infection. Awareness of this risk can help clinicians identify individuals who are more likely to get STDs and therefore target STD testing and appropriate prevention messages.
确定获得新性伴侣与性传播疾病（STD）感染之间的关联，描述获得新性伴侣的预测因素，并比较青少年女性中新建立的性伴侣关系与已确立的性伴侣关系。
从参与一项纵向研究的411名青少年女性（平均年龄17.3岁，44%为黑人，42%为西班牙裔）样本中收集访谈数据和用于STD检测的生物标本。采用逻辑回归分析估计有新性伴侣与STD感染之间的关系。
在12个月的随访期内获得新性伴侣的情况很常见（24%），且与STD感染显著相关（比值比=3.0，95%置信区间=1.6-5.7）。获得新伴侣的预测因素包括年龄较小、首次性交时年龄较小以及在过去30天内性交前饮酒或吸毒。处于新的性伴侣关系中与对伴侣的STD病史和近期与他人发生性行为的不确定性增加显著相关。
处于新的性伴侣关系是STD感染的重要预测因素。了解这种风险有助于临床医生识别更易感染STD的个体，从而针对性地进行STD检测并提供适当的预防信息。
