Nature Human Behaviour 期刊最新一篇文章揭示,我们选择伴侣并非偶然。有很大的概率是,我们会嫁给(娶到)与自己很像的人,例如身高、体重和受教育水平。来自于昆士兰大学的研究团队证实,我们的基因组影响着我们的喜好。

昆士兰大学的遗传学家Peter Visscher课题组的博士后Matthew Robinson及其团队选取了24000对有着欧洲血统的夫妻,对他们的生理和遗传数据进行了分析。他们筛选出他们的生理特征,例如身高、体重指数(BMI),并预测他们伴侣的身高和BMI。随后,研究人员记录了他们伴侣的实际身高,并将于其与预测结果比对。

结果显示,人身高的基因信息与其伴侣的身高之间统计相关性强。而身体质量的遗传信息与伴侣BMI之间的关联性也较强,但是与身高相比相对较弱。总结而言,人们倾向于选择遗传信息与自己类似的伴侣!

这一研究指明了伴侣选择的一种方式:相比于随机,我们选择对象更趋向于相同的遗传特性。这一机制在自然界可见一斑,例如东方蓝知更鸟(Eastern Bluebird)倾向于与羽毛颜色同样鲜艳多彩的知更鸟在一起。如果羽毛颜色、身高、体型大小等被选择的遗传特性有利于物种生存,那么这种交配倾向将有助于后代更好地应对自然选择。

除了身高和体重指数,研究团队还检测了其他遗传特征,例如教育年限。他们在英国选取了7780对夫妻,分析了与受教育年限相关的遗传标记,并且在伴侣之间发现了高度的相关性。这并不是说,我们基于受教育水平选择配偶,但是这一结果意味着,人们倾向于选择情况类似的伴侣。

这些结果表明,配偶选择“影响人类基因组的结构特征”。这种选择增加了遗传特性在后代之间的延续,例如身高。

Psychological Medicin:伙呆!只睡一个男人的女性容易发生性功能障碍?

女性性功能可受多种因素的影响,包括心理健康、年龄、时间和伴侣关系质量等。近日,来自图尔库大学和奥伯学术大学的一项新的研究通过7年的观察各种女性的性功能和与伴侣关系的状态揭示了女性性功能的时间稳定性,其研究结果已发表于Psychological Medicine。 研究共探究了2173例绝经前妇女的数据,该数据来源于芬兰的两个大型数据库集(2006年和2013年)。 科学家使用女性性功能

Psychooncology:年轻癌症患者过的“性福”吗?

最近几年对年轻癌症患者(AYA)的关注越来越多,不过大部分研究集中在AYAs的生育问题上,对该类人群浪漫关系和性方面的研究则很少。研究者进行了一项横断面研究调查AYAs人群的关系情况和性满意度,进而识别该类人群的性别差异。研究共纳入了99名年轻癌症患者,年龄在15-39岁之间,其中33名为男性。在调查期间参与者有浪漫对象,并且完成了关于其对象关系、性活动、性欲的问卷调查。研究数据显示,75名患者对

BMJ:男性是否愿意用避孕套取决于性伴侣有多性感

众所周知,避孕套并不会受到所有人的喜爱。但最新的一项研究表明:对于直男来说,在进行性行为的过程中是否使用安全套取决于对方有多“性感”,而不是对患性病有多敏感。 没错,这项研究表明男性遇到的性伴侣如果越性感,那么他们采取保护性措施的可能性就越低,尽管对方有可能患有性病。 当然,研究者们仅仅调查了51名年龄在19到61岁之间的异性恋男性,因此该研究的规模很小,难以代表在整个群体中的趋势。 但这

Open Heart:一年内失去伴侣,民众房颤风险大幅增加

失去所爱的人是人生最大的挑战和挫折。它可以引起民众出现巨大的心理压力,并增加民众患急性心血管疾病的风险。现在,新的研究指出,亲人死去1年内,民众发生心率不齐的风险增加,同时导致民众出现卒中和心力衰竭的风险也增加。奥尔胡斯大学公共卫生学院的Simon Graff博士和同事共同进行这项研究,并将研究结果发表在Open Heart。众多研究表明,逝去亲人的巨大悲伤可以在短期内对民众的心脏健康造成严重损害

JAMA Intern Med:夫妻同力更易戒掉陋习

英国研究人员19日在《美国医学会杂志·内科学卷》上报告说,如果夫妻一起戒烟、锻炼或减肥,那么他们取得成功的几率更大。 研究分析了3700多对已婚或同居的伴侣,其年龄均已超过50岁,发现要戒掉影响健康坏习惯,其伴侣一道参与进来更容易成功。譬如,在与伴侣同时戒烟的女性中,有50%成功戒烟。而独自戒烟则要困难得多:在伴侣不吸烟的女性中,仅有17%成功戒烟;而伴侣照常吸烟的女性中,只有8%成功戒
