Homicide rates for infants dropped suddenly between 1967 and 1969. The abrupt nature of this decline suggested the change was artifactual. Investigation suggests that two classification revisions instituted at this time were causes of this decline: changes in related codes set forth in the Eighth Revision of the International Classification of Diseases, Adapted, and revision of the standard certificate of death in 1968. Infant homicides may have been disproportionately underrecorded after 1968. (Am J Public Health 1983; 73:195-197.)
1967年至1969年间,婴儿 homicide 率突然下降。这种下降的突然性表明这种变化是人为的。调查表明,当时进行的两项分类修订是导致这种下降的原因:《国际疾病分类(改编本)》第八版中相关编码的变化,以及1968年标准死亡证明的修订。1968年后,婴儿 homicide 可能被过度漏报。(《美国公共卫生杂志》1983年;73:195 - 197) 注:这里homicide 结合语境推测可能是“他杀”之类的意思,但由于专业医学语境可能更准确含义需结合更多背景,仅按字面翻译。
