Analyses of historical skeletal samples provide useful comparisons of the prevalence of skeletal indicators of stress to documentary information on health, diet, and socioeconomic status. A sample of the permanent dentitions of 253 adults from the St. Thomas' Anglican Church 19th-century skeletal sample in Belleville, Ontario, was examined macroscopically for the prevalence of enamel defects on the six anterior maxillary and mandibular teeth. The maximum frequency of hypoplasias on the left mandibular canine is 36.1%. The prevalence of enamel defects is low to moderate compared to almost all other reported frequencies in historical samples, which is consistent with historical descriptions of this developing community of middle to high socioeconomic status Canadians. Hypoplasias are significantly more frequent in males but there are no significant differences in the mean age at death between individuals with hypoplasia and those without. Calculations of the peak ages of occurrence of hypoplasias fall within the commonly observed 2-4-year range. This is not consistent with separate studies, demographic, isotopic and historical, of the introduction of complementary foods to 19th-century Belleville infants and of the weaning process. These results do not support the view that peak ages of occurrence of hypoplastic defects are associated with the cessation of breast-feeding or the weaning process in general. Am. J. Hum.

对历史骨骼样本的分析为压力的骨骼指标患病率与有关健康、饮食和社会经济地位的文献信息提供了有益的比较。对安大略省贝尔维尔市圣托马斯英国国教教堂19世纪骨骼样本中的253名成年人的恒牙列样本进行了宏观检查，以确定上颌和下颌六颗前牙釉质缺陷的患病率。左下颌尖牙发育不全的最高发生率为36.1%。与几乎所有其他历史样本中报告的频率相比，釉质缺陷的患病率较低至中等，这与对这个加拿大中高社会经济地位发展中社区的历史描述一致。发育不全在男性中明显更常见，但有发育不全的个体与没有发育不全的个体在平均死亡年龄上没有显著差异。发育不全发生的高峰年龄计算结果在通常观察到的2 - 4岁范围内。这与对19世纪贝尔维尔婴儿引入补充食物和断奶过程的单独的人口统计学、同位素和历史研究不一致。这些结果不支持发育不全缺陷发生的高峰年龄与一般母乳喂养停止或断奶过程相关的观点。《美国人类生物学杂志》11:513 - 524，1999年。版权所有1999威利 - 利斯公司。
