研究人员测量了 8-14 岁班图族女孩的血浆激素浓度，这些女孩月经初潮较晚，患乳腺癌的风险较低，而白人女孩月经初潮较早，患乳腺癌的风险较高。在研究的所有年龄段中，白种人的血浆脱氢表雄酮 (DHEA) 和 DHEA/雄烯二酮比率均显着高于班图女孩。班图女孩的 LH（黄体生成素）水平较高。营养因素部分控制初潮年龄。与饮食相关的 DHEA 水平可能是青春期开始的触发因素。
Plasma hormone concentations were measured in Bantu girls aged 8-14 yr, who have a late menarche and a low risk of breast cancer, and in Caucasian girls who have an early menarche and are at high risk. Plasma dehydroepiandrosterone (DHEA) and the DHEA/androstenedione ratio were significantly higher in Caucasian than in Bantu girls, at all ages studied. LH [luteinizing hormone] levels were higher in Bantu girls. Nutritional factors partially control the age of menarche. Diet-related DHEA levels may be a trigger for the onset of puberty.
