Natl Health Stat Report:CDC数据表明双性恋人数在增加

2016-01-13 Mechront 译 MedSci原创

CDC数据表明双性恋数目在增加,且女性比男性更可能发生同性性行为。该数据来自于年龄18-44岁的5010名女性和4165名男性,在20011-2013年对其性行为、性吸引、性取向的评估结果与2006-2010年的调查相似。不过2011-2013年的调查发现,女性同性性接触明显高于早期调查结果(17.4% vs. 14.2%),此外更多的女性(5.5% vs. 3.9%)和男性(2.0% vs. 1

CDC数据表明双性恋数目在增加,且女性比男性更可能发生同性性行为。该数据来自于年龄18-44岁的5010名女性和4165名男性,在20011-2013年对其性行为、性吸引、性取向的评估结果与2006-2010年的调查相似。

不过2011-2013年的调查发现,女性同性性接触明显高于早期调查结果(17.4% vs. 14.2%),此外更多的女性(5.5% vs. 3.9%)和男性(2.0% vs. 1.2%)认为自己是双性恋。近期一项研究表明,同性性接触的女性比例是男性的三倍(17.4% vs. 6.2%)。

18-44岁人群中92.3%的女性和95.1%的男性认为自己是异性恋;7.7%的女性和4.9%的男性认为自己是非异性恋,其中1.3%的女性和1.9%的男性认为自己是同性恋,5.5%的女性和2.0%的男性认为自己是双性恋,还有0.9%的女性和1.0%的男性不知道自己的性取向。认为只有异性才具有吸引的力的男性占92.1%,女性占81.0%。

性吸引与性取向有关,但与性行为无关。性行为、性吸引力和性取向因年龄、婚姻或同居状态、教育和种族等存在很大变化。对性行为、性吸引和性取向的准确且及时的信息,可能有助于确定性传播疾病或艾滋病风险人群,进一步采取更好地针对健康的计划和干预措施。

研究者指出,不同问题不同设计等也会导致参与者性行为和性取向结果的变化。且使用相对较小的样本,以估计人口亚群情况,可能会产生不可靠的结果。因此读者应对来自少数人群的结果谨慎看待。未来还将会有覆盖2011-2015数据的报告和亚组分析报告等。
