Abstract

Head circumference is an important growth parameter; it is closely related to brain development in normal infants. Therefore regular meticulous measurements of head circumference can give diagnostic hints of abnormal brain growth, i. e., reduced growth as in severe malnutrition or accelerated as in hydrocephalus, for example. The results presented here are based on the Bonn Longitudinal Study on growth and development; 150 infants (65 preterm and 85 full-term) were measured regularly from birth. Head circumference of the parents was also measured. For the full term infants the highest correlation was found between mother and daughter (r = 0.75), in the preterm infants the highest correlation was seen between mother and son (r = 0.65). In the Bonn Longitudinal Study and in a recent additional Bonn Study no positive secular trend of head circumference was observed which agrees with results of others. Interestingly enough, growth of head circumference behaves completely differently from that of height in the Bonn Study, where a positive secular trend was observed.

[头围增长:亲子相关性及长期趋势]。
头围是一个重要的生长参数;它与正常婴儿的大脑发育密切相关。因此,定期细致地测量头围可以提供大脑异常生长的诊断提示,例如,严重营养不良时的生长减少或脑积水时的生长加速。这里提出的结果是基于波恩增长与发展纵向研究;150名婴儿(65名早产儿和85名足月婴儿)从出生开始定期测量。还测量了父母的头围。对于足月婴儿,母亲和女儿之间的相关性最高(r = 0.75),在早产儿中,母亲和儿子之间的相关性最高(r = 0.65)。在波恩纵向研究和最近的另一项波恩研究中,没有观察到头围的积极长期趋势,这与其他研究结果一致。有趣的是,在波恩研究中,头围的增长与身高的增长完全不同,在波恩研究中观察到一个积极的长期趋势。
