本研究的目的是评估从儿童到成年不同年龄段的身高、体重和体重指数 (BMI) 之间的关系，并探讨青春期时间、身高和 BMI 之间的长期关系。使用 1958 年英国出生队列（1958 年 3 月 3 日至 9 日之间出生的所有儿童）的纵向数据。在 7、11、16、23（自我报告）和 33 岁时测量身高和体重；青春期状态在 11 岁和 16 岁时进行评估。分析了 5700 名女性和 5512 名男性的数据。成人身高从童年起就可以很好地预测，7 岁和 33 岁身高之间具有很强的相关性（男女 r = 0.7）。 BMI 的相关性较弱，特别是在儿童期和成年早期之间（7 岁和 33 岁的男性 r = 0.33，女性 r = 0.37），尽管它们随着年龄的增长而增加。尽管最胖的儿童成人肥胖的风险最高，但大多数肥胖成年人在较早的年龄并不肥胖：33 岁肥胖男性和女性中，分别只有 17% 和 18% 在 7 岁时肥胖。研究发现，青春期时间与 BMI 之间存在强烈且均匀的关联，7-33 岁的较早成熟者的平均 BMI 较高。在这个未经选择的大型样本中对成人 BMI 的适度预测表明，尽管预防儿童肥胖可能是可取的，但大多数肥胖成年人无法从他们的儿童 BMI 中识别出来，因此，预防策略需要以人群为基础。
The purpose of this study was to assess relations among height, weight, and body mass index (BMI) at different ages from childhood to adulthood, and to examine long-term relations among timing of puberty, height, and BMI. Longitudinal data from the 1958 British birth cohort (all children born between March 3rd and 9th, 1958) were used. Height and weight were measured at ages 7, 11, 16, 23 (self-reported), and 33 y; pubertal status was assessed at ages 11 and 16 y. Data for 5700 females and 5512 males were analyzed. Adult height was well predicted from childhood, with strong correlations (r = 0.7 for both sexes) between height at ages 7 and 33 y. Correlations for BMI were weaker, especially between childhood and early adulthood (r = 0.33 for mates and 0.37 for females, ages 7 and 33 y), although they increased with increasing age. Although the fattest children had the highest risks of adult obesity, most obese adults had not been fat at earlier ages: only 17% and 18% of obese 33-y-old men and women, respectively, had been fat at age 7 y. A strong and evenly graded association was found between timing of puberty and BMI, with higher mean BMIs for the earlier maturers at ages 7-33 y. The moderate prediction of adult BMI in this large and unselected sample suggests that although the prevention of childhood fatness may be desirable, most obese adults could not be identified from their childhood BMI, and hence, preventive strategies need to be population-based.
