近些年来,国外关于婚外非商业性性行为中安全套使用的主题研究逐年增多。通过对相关研究成果进行文献综述,发现这些研究成果多数从公共卫生学角度出发,主要的调查研究方法也局限于问卷调查。一般说来,婚外非商业性性行为比商业性性行为涉及更多的社会、文化、心理等多方面的因素,因此,相关研究还存在很多有待进一步深化和拓展的需要。 In recent years, the number of foreign studies on the use of condoms in non-commercial extra-marital sex activities has been increasing year by year. Through literature review of relevant research results, we find that most of these research results are from the perspective of public health, and the main research methods are also limited to the questionnaire. Generally speaking, extra-marital non-commercial sexual behaviors involve more social, cultural and psychological factors than commercial sexual behaviors. Therefore, there are still many needs to be further deepened and expanded in relevant research.
