性传播疾病的预防：行为的改变
STD Prevention: Behavior Change

安全性行为-推动安全性行为所面临的问题

要改变一个人的习惯决不那么容易，而且要改变其性习惯就特别地不容易。可是，既然“安全性行为”确切地悠关生与死的问题，人们应得到他们能够得到的所有的救助。所以，各个国家与国际的公共卫生当局及其私人机构不屈不挠地不断宣传预防AIDS和安全套使用知识。
早先的一些为改变人们行为的宣传运动取得了相对的成功，至少在一些国家是如此：接种免疫疫苗、佩带摩托车头盔与系汽车安全带、减少与戒断吸烟等等，都有一些成就。这些鼓舞人心的成功事例也增强了人们预防AIDS的希望。预防AIDS的知识不可能马上和全部被人听从及考虑，但是，随着时间的过去，即使是小小的成功也能够创造出巨大的变化。
既然如此，有一些问题一定不要被忽视了：许多人在面对新的风险和相应做出反应还有个人的和主观的问题；也有许多人正遭遇到客观的、经济的和政治的阻碍；在任何预防宣传运动能够开展之前，这些问题和阻碍必须要得到克服。

Safer Sex - Problems of Safer Sex Promotion

It is never easy to change one’s habits, and this is especially true of sexual habits. However, since “safer sex“ is literally a matter of life and death, people deserve all the help they can get. Therefore, national and international public health authorities and many private organizations tirelessly repeat the message of AIDS prevention and condom use.
Some previous campaigns for behavior change have been relatively successful, at least in some countries: Getting vaccinated, wearing motorcycle helmets and seatbelts, reducing or giving up smoking. These encouraging examples raise some hope for AIDS prevention as well. Its message may not be heeded promptly and universally, but even small successes can, over time, make an enormous difference.
Still, there are problems that must not be underestimated: Many people have personal, subjective difficulties facing the new risks and acting accordingly. Many also encounter objective cultural, economic and political obstacles, and these have to be overcome before any prevention campaign can take hold.
