Abstract

Aim: This study investigated the association between gestational age and birth size with pubertal timing, measured as peak height velocity, and adult height.

Methods: This retrospective, population-based study was conducted in Sweden in 2023. A sub-group of the 1974 and 1990 GrowUp Gothenburg cohorts was used (n = 4700, 50% males). The subgroup consisted of healthy individuals with Nordic ethnicity, known parental heights and measured adult heights. Data on birth characteristics (gestational age, birth length, birth weight) were collected. Pubertal timing was assessed as age at peak height velocity. Univariable linear regression analysis and bivariate correlations were conducted to answer the research questions.

Results: Gestational age was not associated with age at peak height velocity or adult height. Birth length and weight could explain 12% and 8% (p ≤ 0.001) respectively of attained adult height. However, birth length and birth weight could only explain the variation in age at peak height velocity to a small degree.

Conclusion: This study showed that gestational age is not associated with age at peak height velocity or adult height. A positive relationship was found between birth size, particularly birth length, and adult height. No strong associations were found between birth size and age at peak height velocity.

出生特征、青春期时间和成年身高之间的关系。
目的:本研究调查了胎龄和出生体型与青春期时间(以身高峰值速度测量)和成年身高之间的关系:这项基于人口的回顾性研究于 2023 年在瑞典进行。研究使用了 1974 年和 1990 年哥德堡成长组的一个分组(n = 4700,50% 为男性)。该分组由北欧人种、已知父母身高和测量成人身高的健康人组成。收集了有关出生特征(胎龄、出生身长、出生体重)的数据。青春期时间以身高峰值速度的年龄进行评估。为回答研究问题,进行了单变量线性回归分析和双变量相关分析:结果:妊娠年龄与身高峰值年龄或成年身高无关。出生时的身长和体重可分别解释成年身高的 12% 和 8% (p ≤ 0.001)。然而,出生身长和出生体重只能在很小程度上解释身高峰值速度年龄的变化:这项研究表明,胎龄与身高峰值年龄速度或成年身高无关。出生体型(尤其是出生身长)与成年身高之间呈正相关。出生体型与身高峰值速度年龄之间没有发现很强的关联。
