Adrenarche involves maturation of the hypothalamic‐pituitary‐adrenal axis and increased production of dehydroepiandrosterone and its sulfate ester, dehydroepiandrosterone‐sulfate (DHEA‐S). It occurs at ages 6 to 8 in industrialized populations, marking the transition from childhood to juvenility and cognitive development at middle childhood. Studies in subsistence level populations indicate a later age (8‐9) for adrenarche, but only two such studies currently exist for comparison.

肾上腺功能涉及下丘脑-垂体-肾上腺轴的成熟和脱氢表雄酮及其硫酸酯、脱氢表雄酮-硫酸盐 (DHEA-S) 的产生增加。它发生在工业化人群的 6 至 8 岁，标志着从童年到少年的过渡以及儿童中期的认知发展。对生存水平人群的研究表明肾上腺功能较晚（8-9 岁），但目前只有两项此类研究可供比较。
