    Author: Aswani N, Taylor CJ, McGaw J, Pickering M, Rigby AS.
    Journal: Acta Paediatr; 2003 Sep; 92(9):1029-32. PubMed ID: 14599064.
    Abstract:
    AIM: Normal growth patterns are seen throughout the first decade in children with cystic fibrosis (CF). Growth in the second decade is, however, less satisfactory and may reflect pubertal delay. This study was performed to assess the extent of pubertal delay, to examine factors that influence the timing and magnitude of the pubertal growth spurt, and to establish whether the final height for most CF patients differed significantly from the normal population. METHODS: Thirty subjects (16 male) attending a single centre were studied. Peak height velocity (PHV), final height and ages when achieved were compared with population norms. Outcome data were correlated with disease severity using Shwachman and Chrispin-Norman scores and forced expiratory volume in 1 s. RESULTS: PHV was significantly later in both genders in this CF population compared with Tanner and Whitehouse standards: boys 14.6 y (95% confidence interval (95% CI) 12.4-16.8, p < 0.01) and girls 12.6 y (95% CI 10.5-14.7, p < 0.01). Mean PHV was also lower in both genders (boys 7.7 cm y(-1) and girls 6.4 cm y(-1), both p<0.001). However, final heights did not differ significantly from Freeman standards (height standard deviation scores: males--1.2, females--0.1); 52% of final heights equalled or exceeded the mid-parental centile. CONCLUSION: CF patients showed suboptimal PHVs with a later pubertal growth spurt influenced by disease severity, but eventually achieved a normal final height.
