Data from a Norwegian investigation on family planning were used to study the relation between menarcheal age and spontaneous abortion rate. Abortion rates were found to be 1.5-2 times higher among women with a menarcheal age of 12 years or less than among those with a menarcheal age of 14 years or more. The possibility that the difference in rates could be attributed to social factors was examined, but no significant relation of this kind was found. The connection between menarcheal age and spontaneous abortion rate may explain the low fertility of early maturers reported by Kiernan (Ann Hum Biol 4:301-308, 1977).
来自挪威一项关于计划生育的调查数据被用于研究初潮年龄与自然流产率之间的关系。研究发现，初潮年龄在12岁及以下的女性的流产率比初潮年龄在14岁及以上的女性高1.5至2倍。研究人员检验了流产率差异可能归因于社会因素的可能性，但未发现此类显著关系。初潮年龄与自然流产率之间的联系或许可以解释基尔南（《人类生物学杂志》4:301 - 308，1977年）所报告的早熟者生育能力较低的现象。
