IJERPH:怀孕季节影响胎儿性别

美国研究人员在瑞士杂志《国际环境研究和公共卫生杂志》(International Journal of Environmental Research and Public Health)上报告说,与春季相比,夏季和冬季怀孕的母亲更有可能生女孩。 本研究是第一次基于中国的数据得出相应结论。专家担忧,全球气候变化导致各地季节变化,最终会影响社会人口结构平衡,产生社会问题。 对人类社会与公共卫生构成挑战

美国研究人员在瑞士杂志《国际环境研究和公共卫生杂志》(International Journal of Environmental Research and Public Health)上报告说,与春季相比,夏季和冬季怀孕的母亲更有可能生女孩。 本研究是第一次基于中国的数据得出相应结论。专家担忧,全球气候变化导致各地季节变化,最终会影响社会人口结构平衡,产生社会问题。 对人类社会与公共卫生构成挑战。[pdf free]

美国杜兰大学和中国卫生人口计划委员会合作,基于中国内蒙古的人口专题调查,课题得到国家专项资助, 在2006-2008年内蒙古地区选取具代表性的近3000个家庭进行回顾式追踪调查,并对参与者进行了相应等测试。在依据调查结果进行数学模型推算后,研究者认为,夏季和冬季怀孕的母亲与春季相比,更有可能生女孩,两者相比具有显着的统计学差异。

课题主要研究者杜兰大学公共卫生和热带病研究院全球健康和环境学系的孙文杰博士表示,季节气候因素可以导致出生性别的变异,虽然内在的人类生物学因素有待进一步探索。 两栖类生物的研究已经有确实证据表明温度在出生性别方面的决定性。 哺乳动物也有证据表明性别受到的遗传学、环境因素之间的复杂相互作用。早期基于美国和西伯利亚的人口学观察也有类似的发现,但都未有数学模型的验证。本研究首次采用严格数学模型的推算和验证。

全球气候变化导致的季节而变成了针对社会和公共卫生的构成一项挑战。虽然性别是由基因决定,但是存活的出生人口可能受到气候的影响,潜在的解释是女性相对于男性更能适应极端环境。

在全球气候变化的坏境下,人口结构的失衡的风险加剧。 特别是人口大国的中国,季节的变化带来的负面影响应引起重视。研究人员认为,从总人口学角度看,由于气候变化带来的风险是一个重要的公共卫生问题。课题将进一步探索季节敏感因素的变动和内在性别决定基因表达方面的研究。 下一步研究正在进行中。
