Although inhaled corticosteroid (ICS) therapy is considered safe in children, its potential effect on linear growth remains a matter of concern. The effect of ICS on growth velocity and final adult height has been a subject of debate.1 Several reviews consistently describe small dose-dependent impairments to childhood growth velocity more evident during the first two years of therapy.2-6 Two Cochrane reviews of randomized clinical trials showed a small mean reduction in linear growth (-0.91cm/year for beclomethasone, -0.59 cm/year for budesonide, and -0.39 cm/year for fluticasone) in the first year of treatment in prepubertal children with persistent asthma.7

On the other hand, a 1-year follow-up study on guideline-recommended doses with high adherence in prepubertal children showed that the negative correlation between cumulative ICS dose and height velocity became non-significant after adjustment for age and sex in a multiple regression model.8 Another recent review showed that most of the "real-life" observational studies did not report significant effects of ICS on growth in children.Also, a retrospective study that included 284 asthmatic prepubertal children on long-term treatment with ICS did not reveal height reduction in low or medium dosage.9

The effect on target adult height is another matter of concern. Although several prospective studies denied such effect, ICs were reported to reduce final height (FH) in asthmatic children compared to controls, in a dose- and duration-dependent manner (2.5 ± 2.89 cm lower in boys and 2.0 ± 2.03 cm lower in girls than matched controls) and this effect was also dependent on the type of ICS.10 Data from the Childhood Asthma Management Program (CAMP) prospective trial showed that a larger daily dose of ICS in the first 2 years was associated with a lower adult height (−0.1 cm for each microgram per kilogram of body weight).11 Loke et al.12 noted a slight reduction of about one cm in final adult height which when interpreted in the context of average adult height in England represented a 0.7 % reduction compared to non-ICS users.

The concomitant use of intranasal corticosteroids (INC) raises concerns as well. Among a group who were prescribed more than 750 μg/d of beclomethasone dipropionate and an INC, a lower annual growth velocity from 3 to 5 years of age was demonstrated; however, this was followed by recovery of growth velocity so that the FH attained at the end of the follow-up period was comparable to children receiving lower doses of the same ICS with or without INC.13

A recent systematic review suggests that the drug molecule and delivery device may impact the effect of ICS on growth in children with persistent asthma. However, the evidence was not certain enough and further pragmatic trials and real-life observational studies were recommended.14

It is advisable that before increasing the dose of ICS, a physician should ensure that the child is actually taking the drug through an appropriate device with good technique and that the modifiable environmental triggers and co-morbidities such as environmental tobacco smoke, allergens and obesity have been addressed. It is also important to review the dosage regularly and reduce it whenever possible to the minimal effective dose.15 It is recommended that children be monitored for growth by stadiometry every 3 to 6 months.4

In spite of the measurable effects of ICS on the linear growth, it is important to keep in mind that the safety profile of all ICS preparation is markedly better than that of oral glucocorticoids. Also, asthma as a chronic disease by itself has growth-suppressing effects and this may confound research on the effect of ICS on growth.Nevertheless, physicians prescribing ICS to children should be aware of this possibility and carefully monitor linear growth especially with the concomitant use of nasal corticosteroids.
