This study examined whether iron deficiency (ID) in infancy contributes to problem behaviors in adolescence through its influence on poor regulatory abilities in childhood. Chilean infants (N = 1,116) were studied when there was no national program for iron fortification (1991-1996), resulting in high rates of ID (28%) and iron-deficiency anemia (IDA, 17%). Infants (54% male) were studied at childhood (M = 10 years) and adolescence (M = 14 years). IDA in infancy was related to excessive alcohol use and risky sexual behavior in adolescence through its effect on poor emotion regulation in childhood. Attentional control deficits at age 10 were also related to both infant IDA and heightened risk taking in adolescence. Findings elucidate how poor childhood regulatory abilities associated with infant IDA compromise adjustment in adolescence.
本研究通过考察缺铁（ID）对儿童时期不良调节能力的影响，探讨了婴儿期缺铁是否会导致青少年时期出现问题行为。智利婴儿（N=1116）在没有国家铁强化计划（1991-1996 年）时进行了研究，导致高比例的缺铁（28%）和缺铁性贫血（IDA，17%）。婴儿（54%为男性）在儿童期（M=10 岁）和青春期（M=14 岁）进行了研究。婴儿期的 IDA 通过对儿童时期不良情绪调节的影响，与青少年时期过度饮酒和危险性行为有关。10 岁时的注意力控制缺陷也与婴儿期的 IDA 和青春期冒险行为增加有关。研究结果阐明了与婴儿期 IDA 相关的不良儿童调节能力如何损害青春期的适应能力。
