The frequency and age distribution of linear enamel hypoplasia (LEH) in the dentition of 293 individuals from Latte Period sites (AD 800-1521) on Guam, Mariana Islands, are examined in this study. Individuals dying as subadults (before age 16) and as young adults (ages 16-21) have more frequent LEHs than those who survived to middle or late adulthood, documenting a relationship between LEH-causing stress events and reduced life expectancy. The age distributions of cribra orbitalia and skeletal infection in children who died by age 10 exhibit striking similarities to the etiological age patterns of LEH in children, and those with skeletal infection have more frequent hypoplasias than children without infection. The comorbidity of systemic stress and infection in children, and their impact on life expectancy, are interpreted in the biocultural context of high population density in the large coastal villages of the late prehistoric period in the Marianas.
本研究调查了来自马里亚纳群岛关岛拿铁时代遗址（公元800 - 1521年）的293名个体牙列中线性釉质发育不全（LEH）的频率和年龄分布。未成年（16岁之前）及青年（16 - 21岁）死亡个体的LEH比存活至中年或老年的个体更为常见，这证明了导致LEH的应激事件与预期寿命缩短之间的关系。10岁前死亡儿童的筛孔眶顶和骨骼感染的年龄分布与儿童LEH的病因年龄模式表现出惊人的相似性，且患有骨骼感染的儿童比未感染儿童的发育不全更为频繁。儿童系统性应激与感染的共病情况及其对预期寿命的影响，在马里亚纳史前晚期大型沿海村庄人口密度高的生物文化背景下得到了解释。
