检测脐带血中的5种性激素。从出生到33个月的几个年龄段的三个样本对儿童的力量进行了评估。在不同的年龄，不同的力量测量是不同的，即出生时，俯卧头反应；3个月时，腿力量；6-33个月间，握力。男孩的平均力量得分高于女孩，但性别差异很小，在研究的年龄段没有增加或减少。跨年龄力量评分显示与雄烯二酮有显著关系，性激素和孕酮有显著交互作用。力量得分较高的男孩和女孩都有较低的雄烯二酮。脐血孕酮升高的女孩表现为低强度，而男孩表现为高孕酮的高强度。雄烯二酮和孕酮水平无性别差异。雄烯二酮的发现不会在样本之间复制，但孕酮和性的相互作用在所有三个样本中都是重复的。没有发现力量与其他激素之间的关系：睾酮、雌二醇和雌酮。
Five sex‐steroid hormones were assayed in umbilical cord blood. Strength was assessd in children in three samples at several ages from birth to 33 months. At defferent ages, differents strength measures were tatken, viz., at birth, prone head responses; at 3 months, leg strength; from 6 to 33 months, grip strength. Boys had higher average strength scores than girls but the sex differences were small and did not increase or decrease over the age period studied. Across‐age strength scores showed a significant relation to androstenedione and a significant interaction of sexc and progesterone. Both boys and girls with higher strength scores had lower androstenedione. Girls with high cord blood progesterone showed low strength with boys with high progesterone showed high strength. There were no sex differences in androstenedione or progesterone level. The androstenedione finding did not replicate across samples but the Progesterone × sex interaction was replicated in all three sample. No relationship was found between strength and other hormones assayed: Tstosterone, estradiol, and estrone.
