The incidence of infantile hypertrophic pyloric stenosis was measured in the West Midlands Health Region between 1974 and 1980. It increased from 2.1/1000 Caucasian births in 1974 to 3.5/1000 in 1980 and reflects a reported increase in Central Scotland. Several artefacts were excluded--for example, repeat admissions to the same hospital, transfers to other hospitals, and changes in treatment and in diagnostic standards. Two main demographic changes were excluded as explanations, ethnic changes and changes in the birth rank distribution. The increase is therefore considered real and may be related to changes in breast feeding practice.
1974年至1980年间,西米德兰兹郡健康区对婴儿肥厚性幽门狭窄的发病率进行了测量。其发病率从1974年每1000例白种人出生中的2.1例增至1980年的3.5例,这与苏格兰中部地区报告的发病率上升情况相符。一些人为因素被排除在外,例如同一医院的重复入院、转至其他医院以及治疗和诊断标准的变化。另外,作为解释因素的两个主要人口统计学变化,即种族变化和出生顺序分布变化也被排除。因此,这种发病率的上升被认为是真实的,可能与母乳喂养方式的改变有关。
