Validity of height velocity as a diagnostic criterion for idiopathic growth hormone deficiency and Turner syndrome.

A deflecting growth curve over several years is sometimes the only indication for the possible presence of a growth disorder. In this study we looked at the potential diagnostic role of long-term downward deflection of the growth curve. It reports on the diagnostic validity of height velocity over 1, 2 or 3 years for isolated idiopathic growth hormone deficiency and for Turner syndrome in prepubertal children with a height that is still above -2.5 standard deviation scores (SDS). 1-year height velocity was found to have no diagnostic value because of an almost complete overlap of height velocity distributions with normal prepubertal children. However, height velocity over 3 years was found to have an acceptable validity in children 5-12 years old. In this age range a change in height SDS of -0.75 can be used as a valid criterion for further examination of karyotype and GH secretion capacity even if there are no other clear signs of a particular growth disorder.     

Effect of chronic clonidine treatment on urinary growth hormone excretion and linear growth in children with short stature

Eleven prepubertal children with short stature were treated with clonidine (0.15 mg/m2 daily) for a period of 1 year. The effect of this drug was evaluated on both clinical (growth velocity, height standard deviation scores for chronological age and bone age) and hormonal (urinary growth hormone excretion and insulin-like growth factor I) parameters. Our study shows that long-term clonidine administration in children with short stature did not result in significant differences in growth velocity, height standard deviation scores for chronological age and bone age, insulin-like growth factor I or in urinary growth hormone excretion.     

Trend in Height of Turkish and Moroccan Children Living in The Netherlands

ObjectivesTo study trends in height of Turkish and Moroccan immigrant children living in The Netherlands, to investigate the association between height and background characteristics in these children, and to calculate height-for-age-references data for these groups.DesignNationwide cross-sectional data collection from children aged 0 to 18 years by trained professionals in 1997 and 2009. The study population consisted of 2,822 Turkish 2,779 Moroccan, and 13,705 Dutch origin children in 1997and 2,548 Turkish, 2,594 Moroccan, and 11,255 Dutch origin children in 2009. Main outcome measures: Mean height in cm, and mean height standard deviation scores.ResultsIn 2009, mean height at the age of 18y was similar for Turkish and Moroccan children: 177 cm for boys and 163 cm for girls, which was 2 to 3 cm taller than in 1997. Still, Turkish and Moroccan adolescents were 5.5 cm (boys) to 7 cm (girls) shorter than their Dutch peers. No significant differences were found in mean height standard deviation scores across the educational level of the parents, geographical region, primary language spoken at home, and immigrant generation.ConclusionsWhile the secular height increase in Dutch children came to a halt, the trend in Turkish and Moroccan children living in The Netherlands continued. However, large differences in height between Turkish and Moroccan children and Dutch children remain. We found no association with the background characteristics. We recommend the use of the new growth charts for children of Turkish and Moroccan origin who have a height-for-age below -2SD on the growth chart for Dutch children.     

Inhaled corticosteroids for abnormal pulmonary function in children with a history of Chronic Lung Disease of Infancy: study protocol [ISRCTN55153521]

Background

There is considerable evidence from the literature that children with chronic lung disease of infancy (CLD) have abnormal pulmonary function in childhood and this could have an impact on their life quality and overall health. There are similarities between CLD and asthma, and corticosteroids are the mainstay treatment for asthma. Many physicians use inhaled corticosteroids in children with CLD with no evidence. Therefore we wish to conduct a randomized double-blinded placebo controlled trial to test for the role of inhaled corticosteroids in children aged from3 to 9 years with a history of CLD. Our primary hypothesis will be that inhaled corticosteroids are beneficial in children with CLD.

Methods

Our primary hypothesis is that using inhaled steroids; Beclomethasone Dipropionate (QVAR) 100 mcg 2 puffs 2 times a day for 6 weeks will improve the respiratory system resistance and the quality of life in children with CLD.

Discussion

We propose that Beclomethasone Dipropionate (QVAR) will affect the pulmonary function after 6 weeks of treatment. In summary we think that our study will highlight knowledge on whether the use of inhaled steroids is clinically effective for CLD.     

Final height, armspan, subischial leg length and body proportions in juvenile chronic arthritis. A long-term follow-up study

OBJECTIVE: Assessment of growth disturbances in adults with a history of juvenile chronic arthritis (JCA). MATERIAL AND METHODS: Sixty-five subjects, 52 premenopausal females and 13 males with a mean age (range) of 32.2 years (22.3-49.4) participated. Mean age at disease onset was 5.7 years (0.8-15.8) and mean disease duration was 12.4 years (0.4-32). The follow-up time ranged from 18.7 to 46.9 years with a mean of 26.4 years. For each participant standard deviation scores (z-scores) for final height, delta-height (the difference between observed and expected height), armspan, subischial leg length and sitting height ratio, were calculated. RESULTS: The study group as a whole did not exhibit linear growth impairment. The categorical distribution of heights differed significantly from a expected distribution in a healthy population (p < 0.001). A height z-score < -2 SD was present in 10.7% of the study group, of whom all had polyarticular course of JCA. Polyarticular and systemic course of JCA (versus pauciarticular) (p = 0.022), systemic steroid treatment (p = 0.006) and Steinbrocker functional class II-IV (vs. I) in 1979 (p = 0.043) were variables associated with reduced delta-height. In linear regression analyses, disease severity defining variables were statistically significant predictors of reduced final height and armspan. 27% of the study subjects had significantly reduced arm span (p < 0.001). Subischial leg length and body proportions (sitting height ratio) were normal. CONCLUSION: Our findings suggest that functionally impaired polyarticular and systemic JCA patients treated with systemic steroids may be at an increased risk of developing reduced final height and armspan. Disease control achieved by an aggressive therapeutic approach, if possible with a minimal use of systemic steroids, may reduce growth impairment in JCA.     

Effect of growth hormone on short normal children.

The growth of 26 short normal prepubertal children (mean age 8.4, height velocity standard deviation score for chronological age between +0.4 and -0.8) was studied for two years. Sixteen children were treated with somatrem (methionyl growth hormone) during the second year, and the remaining 10 children served as controls. During one year of treatment the height velocity standard deviation score for chronological age increased from the pretreatment mean of -0.44 (SD 0.33) to +2.20 (1.03). These values represented a change in height velocity from a pretreatment mean of 5.3 cm/year (range 4.6-6.9) to 7.4 cm/year (range 5.7-9.9). In the control group the height velocity standard deviation score was unchanged. Bone age advanced by 0.75 (0.33) years in the treated group compared with 0.70 (0.18) years in the control group. There was a significant increase in the height standard deviation score for bone age (0.63 (0.55] in the treated group. Multiple regression analysis of predictive factors contributing to the change in height velocity standard deviation score over the first year of treatment showed that the dose of growth hormone and pretreatment height velocity standard deviation score were important, together yielding a regression correlation coefficient of 0.80. The only metabolic side effect of treatment was an increase in fasting insulin concentration, which may be an important mediator of the anabolic effects of growth hormone. Treatment had no effect on thyroid function, blood pressure, or glucose tolerance. At the end of the treatment year seven of the 16 treated children had developed antibodies to growth hormone, but they were present in low titre with low binding capacity and in no child was growth attenuated. Biosynthetic growth hormone improved the height velocity of children growing along or parallel to the third height centile, but the effects on height prognosis need to be assessed over a longer period.     

Effects of growth hormone treatment on cognitive function and head circumference in children born small for gestational age

Short stature is not the only problem faced by children born small for gestational age (SGA). Being born SGA has also been associated with lowered intelligence, poor academic performance, low social competence and behavioural problems. This paper summarizes the results of a randomized, double-blind, growth hormone (GH) dose-response study (1 or 2 mg/m2/day [ approximately 0.035 or 0.07 mg/kg/day]) on growth, intelligence quotient (IQ) and psychosocial functioning in 79 children born SGA at the start, and after 2 and 8 years of GH therapy, and addresses the associations with head circumference. Mean age at start of therapy was 7.4 years; mean duration of GH treatment was 8.0 years. In 2001, 91% of children born SGA had reached a normal height (> -2.0 standard deviation score [SDS]). Block-design s-score (Performal IQ) and Total IQ score increased (p < 0.001 for both indices) from scores significantly lower than those of Dutch peers at the start of therapy (p < 0.001) to scores that were comparable to those of Dutch peers in 2001. Vocabulary s-score (Verbal IQ) was normal at the start of therapy and remained so over time. Externalizing Problem Behaviour SDS and Total Problem Behaviour SDS improved during GH therapy (p < 0.01-0.05) to scores comparable to those of Dutch peers. Internalizing Problem Behaviour SDS was comparable to that of Dutch peers at the start of therapy and remained so, whereas Self-Perception improved from the start of GH therapy until 2001 (p < 0.001), when it reached normal scores. Head circumference SDS at the start of GH therapy and head growth during GH therapy were positively related to all IQ scores (p < 0.01), whereas neither were related to height SDS at the start of, or to its improvement during, GH therapy. A significant improvement in height and head circumference in children born SGA was seen after only 3 years of GH therapy, in contrast to randomized SGA controls. In conclusion, most children born SGA showed a normalization of height during GH therapy and, in parallel to this, a significant improvement in Performal IQ and Total IQ. In addition, problem behaviour and self-perception improved significantly. Interestingly, Performal, Verbal and Total IQ scores were positively related to head circumference, both at the start of, and during, GH therapy; head circumference increased in GH-treated children born SGA, but not in untreated SGA controls. These results are encouraging but also warrant confirmational studies and further investigations into the effects of GH on the central nervous system.     

Serum IGF-I and IGFBP-3 levels of Turkish children during childhood and adolescence: establishment of reference ranges with emphasis on puberty

AIMS/METHODS: We established age- and sex-related reference ranges for serum insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-3 (IGFBP-3) levels in 807 healthy Turkish children (428 boys, 379 girls), and constructed a model for calculation of standard deviation scores of IGF-I and IGFBP-3 according to age, sex and pubertal stage. RESULTS: Serum IGF-I and IGFBP-3 concentrations tended to be higher in girls compared to boys of the same ages, but the differences were statistically significant only in pubertal ages (9-14 years) for IGF-I and only in prepubertal ages for IGFBP-3 (6-8 years) (p < 0.05). Peak IGF-I concentrations were observed earlier in girls than boys (14 vs. 15 years, Tanner stage IV vs. V) starting to decline thereafter. IGFBP-3 levels peaked at age 13 and at Tanner stage IV in both sexes with a subsequent fall. Serum levels of IGF-I and IGFBP-3 increased steadily with age in the prepubertal stage followed by a rapid increase in IGF-I in the early pubertal stages. A relatively steeper increase in IGF-I but not in IGFBP-3 levels was observed at age 10-11 years in girls and at 12-13 years in boys which preceded the reported age of pubertal growth spurt. At late pubertal stages, both IGF-I and IGFBP-3 either did not change or decreased by increasing age. Interrelationships between growth factors and anthropometric measurements have been described, and the physiologic consequences of these have been discussed in detail. CONCLUSIONS: Differences in the pattern of IGF-I and IGFBP-3 in the present paper and those reported in other studies emphasize the importance of locally established reference ranges. Establishment of this reference data and a standard deviation score prediction model based on age, sex and puberty will enhance the diagnostic power and utility of IGF-I and IGFBP-3 in evaluating growth disorders in our population.     

Growth response of Egyptian children with idiopathic short stature during four years of growth hormone therapy

BACKGROUND:

Multiple factors affect the growth response to recombinant human growth hormone (rhGH) in children with idiopathic short stature (ISS).

AIM:

To evaluate the growth responses of children with ISS treated with rhGH, aiming to identify the predictors of growth response.

MATERIALS AND METHODS:

We studied 120 cases, 90 males (75%), with a mean age of 13.8±2.7 years and 30 females (25%), with a mean age of 12.3±2.5 years. All patients received rhGH with a standard dose of 20 IU/m²/week. The calculated dose per week was divided into six days and given subcutaneous at night.

RESULTS:

A significant positive trend was detected in the delta changes of all anthropometric data. For the first year, the growth response was positively correlated to CA and BA delay and negatively correlated to height, weight and IGF-1 SDSs. For the second year, the growth response was correlated positively to first year growth velocity, BA, triceps skin fold thickness SDS and deviation from target height, and negatively correlated to weight, IGFBP3 SDS and target height SDS. For the third year, the growth response was positively correlated to five variables namely target height, 2^nd year growth velocity, IGF-1 SDS, weight SDS and triceps skin fold thickness SDS. For the fourth year, growth response was positively correlated to 2^nd and 3^rd year growth velocity, BA, deviation from target height and weight/ height SDS.

CONCLUSION:

Our study showed multiplicity of predictors that is responsible for response in ISS children treated with rhGH, and BA was an important predictor.     

Growth hormone therapy in noonan syndrome

Noonan syndrome (NS) is an autosomal dominant disorder that can be difficult to diagnose. Growth retardation is a consistent feature, however, and although children are not typically growth hormone (GH) deficient, a minority may have suboptimal GH levels. An ongoing multicentre study examining the safety and efficacy of GH therapy in NS showed increases in height standard deviation scores (SDS; p < 0. 0001) and height velocity (p < 0.0001) after 12 months of GH at pharmacological doses. There was no increase in mean maximal cardiac left ventricular wall thickness during the 12-month treatment period. Long-term follow-up data covering 3 years of GH therapy showed sustained increases in height SDS and height velocity compared with baseline (p < 0.02). Further large and appropriately controlled studies of high-quality design are essential to further our understanding of NS and to establish the long-term safety and efficacy of GH.     

Growth of asthmatic children during treatment with budesonide: a double blind trial.

OBJECTIVE--To determine whether the inhaled glucocorticosteroid budesonide has any adverse effect on short term linear growth in children with mild asthma. SETTING--Outpatient clinic in secondary referral centre. PATIENTS--15 children aged 6-13 years with normal statural growth velocity during the previous year, no signs of puberty, and no use of systemic or topical steroids in the two months before the study. DESIGN OF INTERVENTIONS--Double blind, randomised crossover trial with two active periods in which budesonide was given in divided daily doses of 200 micrograms and 800 micrograms. During run in and two washout periods placebo was given. After the second washout period the children received open treatment with 400 micrograms budesonide daily. All periods were of 18 days'' duration. MAIN OUTCOME MEASURE--Growth of the lower leg as measured twice a week by knemometry. RESULTS--Mean growth velocity of the lower leg was 0.63 mm/week during run in and during washout 0.64 mm/week. Budesonide treatment was associated with a significant dose related reduction of growth velocity: the mean reduction in growth velocity during treatment was 0.11 (95% confidence interval -0.15 0.36 (0.13 to 0.59) mm/week with 800 micrograms budesonide (p less than 0.05; Page''s test). During treatment with 400 micrograms budesonide a reduction of 0.17 (-0.10 to 0.45) mm/week was found. CONCLUSIONS--Treatment with inhaled budesonide is associated with a dose related suppression of short term linear growth in children with mild asthma.     

Intermittent recombinant growth hormone treatment in short children born small for gestational age: four-year results of a randomized trial of two different treatment regimens

BACKGROUND: Treatment of short children born small for gestational age SGA with recombinant human growth hormone r-hGH increases growth velocity during childhood. As in other indications, the growth velocity in these patients is more marked during the first year of treatment and then decreases. This study was undertaken to evaluate the efficacy of different r-hGH treatment schedules (67 microg/kg/day in a discontinuous or continuous regimen) during the second year of r-hGH treatment by comparing height velocity changes and total gain of height over a 4-year period. METHODS: 58 growth-retarded SGA children aged 2-5 years were randomized to a TOTO regimen (4 years alternating treatment (T) and observation (O), n = 30) or a TTOO regimen (2 years' treatment, followed by 2 years' observation, n = 28). Height velocity HV and total height gain were assessed during the 4-year study. RESULTS: In both groups, HV and HV standard deviation score HV-SDSCA increased during treatment and decreased during observation periods. Interruption of treatment in the TOTO group did not result in a better gain in height standard deviation score H-SDSCA when compared with the TTOO group. After 4 years of study, the gain in H-SDSCA was 1.4 + or - 01 in the TOTO group and 1.6 + or - 0.2 in the TTOO group leading to a mean height of -2.0 + or - 1.0 SDS and -2.0 + or - 0.8 SDS, respectively. The rate of bone maturation was similar in the two groups. CONCLUSIONS: In short SGA children, TOTO and TTOO regimens produced significant improvements in growth during r-hGH treatment. However, treatment interruption after 1 year did not influence the overall gain in height SDS when compared with 2 years' continuous treatment.     

Growth problems in children with asthma

Growth problems are often seen in children with asthma. Rarely, these problems may be caused by poor asthma control. Negatively-deviating growth curves in asthmatic boys aged 8-15 years are often associated with a chronic delay in growth and puberty. Daily treatment with any dose of systemic corticosteroids suppresses the growth rate for as long as the treatment is maintained. The risk of growth rate suppression due to inhaled corticosteroids depends on the dose, administration regimen and delivery device. The risk becomes significant with > or =800 microg budesonide from a metered-dose inhaler with a spacer, and with > or =400 microg budesonide or fluticasone propionate from a dry-powder inhaler. Regardless of the treatment modality applied, all children with asthma should have their height growth measured at least every 6 months, and indications for endocrine work-up should follow general criteria for a growth-insufficient child.     

Remote Monitoring of Inhaled Bronchodilator Use and Weekly Feedback about Asthma Management: An Open-Group,Short-Term Pilot Study of the Impact on Asthma Control

Objective

Adequate symptom control is a problem for many people with asthma. We asked whether weekly email reports on monitored use of inhaled, short-acting bronchodilators might improve scores on composite asthma-control measures.

Methods

Through an investigational electronic medication sensor attached to each participant''s inhaler, we monitored 4 months'' use of inhaled, short-acting bronchodilators. Participants completed surveys, including the Asthma Control Test^TM (ACT), to assess asthma control at entry and monthly thereafter. After the first month, participants received weekly email reports for 3 months. The reports summarized inhaled bronchodilator use during the preceding week and provided suggestions derived from National Asthma Education and Prevention Program (NAEPP) guidelines. Paired t-tests and random-effects mixed models were implemented to assess changes in primary asthma endpoints.

Results

Thirty individuals participated in the 4-month study; 29 provided complete asthma control information. Mean age was 36.8 years (range: 19–74 years); 52% of respondents were female. Mean ACT scores were 17.6 (Standard Deviation [SD]  = 3.35) at entry and 18.4 (SD = 3.60) at completion of the first month. No significant difference appeared between ACT values at entry and completion of the first month (p = 0.66); however, after participants began receiving email reports and online information about their inhaler use, mean ACT scores increased 1.40 points (95% CI: 0.61, 2.18) for each subsequent study month. Significant decreases occurred in 2-week histories of daytime symptoms (β = −1.35, 95% CI: −2.65, −0.04) and nighttime symptoms (β = −0.84, 95% CI: −1.25, −0.44); no significant change in activity limitation (β = −0.21, 95% CI: −0.69, 0.26) was observed. Participants reported increased awareness and understanding of asthma patterns, level of control, bronchodilator use (timing, location) and triggers, and improved preventive practices.

Conclusions

Weekly email reports and access to online charts summarizing remote monitoring of inhaled bronchodilator frequency and location were associated with improved asthma control and a decline in day-to-day asthma symptoms.     

Clinical standards for growth velocity in height of Belgian boys and girls,aged 2 to 18 years

The present paper presents the first clinical standards for growth velocity in height of Belgian boys and girls, based on purely longitudinal data. Growth charts are provided with centiles of height for age, along with the growth velocity curves of the typical early, average and late maturing child in the population. These new growth velocity standards provide centile lines which allow to judge whether a child's growth velocity over a one-year interval lies within the limits of normal variation for his age, irrespective of his stage of maturation. They also provide information about variability in the individual patterns of growth velocity in the population and can, as such, also be used to evaluate the normality of a child's pattern in growth velocity over a longer period of time. Age at peak velocity occured in 95% of the children within an age range of about 4 years. The average age at peak height velocity at puberty was 14.0 years (S.D.=1.0) in boys and 11.6 years (S.D.=0.9) in girls. Peak height velocity was in the average 9.1 cm/year (S.D.=1.4) in boys and 7.5 cm/year (S.D.=1.1) in girls. The representativity of these new standards with respect to the actual Belgian population was tested by comparison with recent cross-sectional data, collected on a large number of subjects. These new charts will find useful applications in longitudinal health screening surveys, and in clinical follow-up studies, where interest lies in the examination of a child's growth retardation in relation to some disease, or catch-up growth, as a response to subsequent medical treatment.     

Patterns of Growth Associated With the Timing of Adiposity Rebound

This study was undertaken to evaluate the effects of age of adiposity rebound (AR) on measures of fat mass between ages 7 and 11 years, maturity, and adiposity in 458 children from a birth cohort studied to age 26 years. Patterns of growth between ages 3 and 26 years and changes in fat mass index between 7 and 11 years in groups with early (<5.5 years for boys and <5 years for girls), average (between 5.5 and 7.5 years for boys and between 5 and 7 years for girls), and late AR (≥7.5 years for boys and ≥7 years for girls) are described. The mean z‐scores for BMI, height, and weight increased between age 3 years and adolescence in the early‐rebound group and decreased in the late‐rebound group. The differences were maintained until adulthood for BMI and weight. Disproportionately high increases in fat mass index during growth (7–11 years), more advanced bone age in boys at age 7 years, and earlier menarche in girls were evident in the early‐rebound group. The relative risks at 26 years of being overweight (BMI 25–29.9 kg/m²) and obese (BMI ≥30 kg/m²) were 2.70 (95% confidence interval (CI): 1.55, 4.66) and 5.91 (95% CI: 3.03, 11.55) respectively, using the average group as the reference. The corresponding relative risks for adult waist girths exceeding international cut points were 2.12 (95% CI: 1.09, 4.13) and 3.32 (95% CI: 1.46, 7.54). Thus, early rebound is associated with increased depositions of fat in middle childhood, and risks associated with early rebound persist at least until early adulthood.     

Controlled trial of budesonide given by the nebuhaler in preschool children with asthma.

OBJECTIVE--To determine whether the inhaled corticosteroid budesonide, given by a Nebuhaler spacing device, was effective in prophylaxis of asthma in preschool children. DESIGN--Double blind, placebo controlled, random order crossover trial with two week practice run in period. SETTING--Outpatient clinic referrals in secondary referral centre. PATIENTS--39 children aged 2-6 years selected for the following: able to use Nebuhaler; parents able to complete record card; poorly controlled asthma (defined); not already on systemic or inhaled steroids. Eleven withdrew for various reasons not connected with intolerance to budesonide. Age, sex, other atopies, and symptoms during run in period were similar in the 28 children who completed the trial and in the 11 who withdrew. INTERVENTIONS--Budesonide 200 micrograms or placebo (both one puff) given twice daily during 6-week treatment or control periods, using Nebuhaler after prior training. Three week "washout" at crossover. Compliance monitored by weighing canisters. Patients withdrawn if their acute attacks required treatment with systemic steroids. END POINT--Control of asthma. MEASUREMENTS AND MAIN RESULTS--Peak expiratory flow rate measured twice daily where cooperation allowed. Diary of symptoms and concomitant drug use kept daily. Results showed mean peak flow significantly higher (12% in mornings, 14% in evenings) in second three weeks of intervention compared with control period (95% confidence intervals 6.3-17.3% and 7.2-21.0%). Supplementary bronchodilator drugs reduced by 50% during intervention periods. CONCLUSIONS--Budesonide given by Nebuhaler is effective prophylaxis for preschool children with frequent asthma.     

Theophylline in the management of airflow obstruction. 2. Difficult drugs to use,few clinical indications.

The narrow therapeutic index, potential toxicity, and need to monitor plasma concentrations make theophyllines difficult to use. Other drugs provide comparable or better bronchodilator and prophylactic efficacy. In asthma theophyllines should be considered for chronic stable asthma when treatment with optimal doses of inhaled steroids and bronchodilators fails to provide adequate control; for nocturnal asthma; and for prophylaxis and relief of symptoms in children and adults when inhaled treatment cannot be given. In general, theophyllines cannot be recommended for chronic airflow obstruction. A trial of theophylline is reasonable in individual patients whose symptoms remain troublesome despite a trial of steroids and optimal doses of inhaled bronchodilators.     

General body growth in children with cleft palate and related disorders: age differences

Clefts of the lip and palate, separately or in combination, are among the most frequent congenital defects seen today. Their etiology is heterogeneous and may include hormonal factors, which suggest the possibility of growth effects. Whether affected children are smaller than others has not been determined. We recently showed that growth status is associated with type of cleft. We hypothesized genetic alterations in metabolic pathways that alter prenatal growth, producing clefts; some of these alterations also alter postnatal growth. Since the levels of growth-regulating hormones change during ontogeny, we expected age differences in the degree of growth deficit seen. To test this hypothesis, we examine here the cross-sectional means and distributions of standard deviation (z) scores for height and body mass indices (BMIs) for 144 children with the diagnoses unilateral cleft lip and palate (uCLP) and isolated cleft palate (iCP). We find that alteration in growth status is associated with age group as well as sex and diagnosis.     

Early anthropometric indices predict short stature and overweight status in a cohort of Peruvians in early adolescence

While childhood malnutrition is associated with increased morbidity and mortality, less well understood is how early childhood growth influences height and body composition later in life. We revisited 152 Peruvian children who participated in a birth cohort study between 1995 and 1998, and obtained anthropometric and bioimpedance measurements 11-14 years later. We used multivariable regression models to study the effects of childhood anthropometric indices on height and body composition in early adolescence. Each standard deviation decrease in length-for-age at birth was associated with a decrease in adolescent height-for-age of 0.7 SD in both boys and girls (all P < 0.001) and 9.7 greater odds of stunting (95% CI 3.3-28.6). Each SD decrease in length-for-age in the first 30 months of life was associated with a decrease in adolescent height-for-age of 0.4 in boys and 0.6 standard deviation in girls (all P < 0.001) and with 5.8 greater odds of stunting (95% CI 2.6-13.5). The effect of weight gain during early childhood on weight in early adolescence was more complex to understand. Weight-for-length at birth and rate of change in weight-for-length in early childhood were positively associated with age- and sex-adjusted body mass index and a greater risk of being overweight in early adolescence. Linear growth retardation in early childhood is a strong determinant of adolescent stature, indicating that, in developing countries, growth failure in height during early childhood persists through early adolescence. Interventions addressing linear growth retardation in childhood are likely to improve adolescent stature and related-health outcomes in adulthood.
