目的：确定社会身高不平等是否会发生代际变化。方法：目标人群是1958年出生的英国队列人群，均出生于1958年3月3日至9日，一直持续到1991年，以及该人群中三分之一的后代。主要结果是在7、11、16和33岁(队列成员)和1次在4-18岁(后代)测量身高。多水平模型应用于社会阶层与(A)从儿童到成人的成长轨迹(队列成员)、(B)身高(后代)和(C)世代身高增量的关联。结果：在队列成员中观察到身高不平等，在I和II类以及IV和V类之间的所有年龄差异>；2.0 cm；到成年，男孩的平均身高差异显著下降，女孩略有下降。两代人之间出现了一种长期的趋势。在第I和第II班中，男性后代的平均身高与其父亲相近，而在第IV和第V班，男孩的平均身高增加了2.1厘米(p
Objective: To determine whether social inequalities in height change across generations.Methods: The target population was from the 1958 British birth cohort, all born 3rd-9th March 1958, followed to 1991, and the offspring of one third of this population. Main outcomes were height measured at 7, 11, 16, and 33 years (cohort members) and once at 4-18 years (offspring). Multilevel models applied to associations of social class of origin with (a) child-to-adult growth trajectory (cohort members), (b) height (offspring), and (c) generational height increment.Results: Height inequalities were observed among cohort members, with differences >2.0 cm at all ages between classes I and II, and IV and V. By adulthood, the difference in mean height had declined significantly in boys and slightly in girls. A secular trend was seen between the two generations. While male offspring had a similar mean height to their fathers in classes I and II, boys in classes IV and V gained 2.1 cm (p
