A second survey of age at menarche in north-east England, how it is affected by family environment and how it affects physique, was carried out in 1960-70 on a large sample of schoolgirls in the suburbs of Newcastle. Age at menarche shows no independent effect of social class or of position in sibship, but is strongly influenced by the size of family in which a girl grows up. Menarche is associated with pronounced increments in height and weight, in the presence of which no consistent effects of variables of the family environment on physique can be clearly identified. The results are very similar to those from the first study in South Shields, County Durham.
1960年至1970年间，在纽卡斯尔郊区的大量女学生样本中，对英格兰东北部的初潮年龄、家庭环境如何影响初潮年龄以及初潮年龄如何影响体格进行了第二次调查。初潮年龄不受社会阶层或出生顺序的独立影响，但受女孩成长家庭规模的强烈影响。初潮与身高和体重的显著增加有关，在此情况下，家庭环境变量对体格没有一致的明显影响。结果与达勒姆郡南希尔兹的第一项研究结果非常相似。
