To understand the epidemiological characteristics and changing patterns of HIV transmission through heterosexual contact since 2008, and to project the influences of heterosexual transmission mode on the HIV epidemic in China.
Demographic data and history of exposure in newly identified HIV/AIDS cases aged 15 years or older, through heterosexual transmission mode from 2008 to 2014, were collected and analyzed.
The number of HIV/AIDS cases caused by heterosexual transmission increased from 23 402 in 2008, to 68 671 in 2014. The proportion of heterosexual transmission mode increased from 8.7% in 2008 to 66.4% in 2014. Among these cases, the proportion of males increased from 55.3% in 2008 to 68.2% in 2014. Among those who reported acquiring HIV through heterosexual contact, the proportion of cases through extramarital sexual acts out of all the newly report ones, increased from 78.2% in 2008 to 88.2% in 2014. This mode of infection accounted for 85.2% in the age 15 to 49 years group, comparing to 84.2% in the age group of 50 years old or above. The proportion of reported HIV infections through extramarital sexual acts appeared 93.8% on males while 69.0% on females, with statistically significant difference (χ(2)=36 000.000, P<0.001).
As the predominant factor of HIV/AIDS epidemic, currently in China, heterosexual transmission showed diversities in different sub-epidemic areas, gender or age groups. Tailored strategies were urgently needed for health education and highrisk behavioral intervention, according to the local epidemic driven factors, respectively.
了解2008年以来经异性接触传播艾滋病病毒（HIV）的流行特征及变化趋势，预测异性传播模式对我国HIV疫情的影响。
收集并分析2008年至2014年15岁及以上新报告的经异性接触传播HIV/AIDS病例的人口学资料及暴露史。
经异性接触传播导致的HIV/AIDS病例数从2008年的23402例增加到2014年的68671例。异性传播模式的比例从2008年的8.7%上升至2014年的66.4%。其中男性病例比例从2008年的55.3%增至2014年的68.2%。在报告经异性接触感染HIV的病例中，新报告病例中经非婚性行为感染的比例从2008年的78.2%升至2014年的88.2%。该感染途径在15至49岁年龄组占85.2%，50岁及以上年龄组占84.2%。报告经非婚性行为感染HIV的比例男性为93.8%，女性为69.0%，差异有统计学意义（χ(2)=36000.000，P<0.001）。
作为我国HIV/AIDS流行的主要因素，目前经异性接触传播在不同子流行地区、性别及年龄组存在差异。需根据当地流行驱动因素，分别制定针对性的健康教育和高危行为干预策略。
