Abstract
AIM Height velocity is considered a key auxological tool to monitor growth, but updated height velocity growth charts are lacking. We aimed to derive new French height velocity growth charts by using a big-data approach based on routine measurements. METHODS We extracted all growth data of children aged 1 month-18 years from the electronic medical records of 42 primary care physicians, between 1 January 1990 and 8 February 2018, throughout the French metropolitan territory. We derived annual and biannual height velocity growth charts until age 15 years by using the Lambda-Mu-Sigma method. These new growth charts were compared to the 1979 French and 2009 World Health Organisation (WHO) ones. RESULTS New height velocity growth charts were generated with 193 124 and 209 221 annual and biannual values from 80 204 and 87 260 children, respectively, and showed good internal fit. Median curves were close to the 1979 French or 2009 WHO ones, but SD curves displayed important differences. Similar results were found with the biannual height velocity growth charts. CONCLUSION We produced new height velocity growth charts until age 15 years by using a big-data approach applied to measurements routinely collected in clinical practice. These updated growth charts could help optimise growth-monitoring performance.

Abstract
The double burden of malnutrition (DBM) is a significant public health issue in South and Southeast Asia (SA and SEA). This study aimed to assess the impact of using local and regional ethnicity-specific anthropometric references versus international references on the prevalence of DBM in these regions.A narrative review of DBM prevalence using local versus international standards was conducted. Additionally, deidentified datasets from India and Indonesia were analyzed to evaluate the effectiveness of different growth standards in identifying DBM. Anthropometric Z-scores were compared, and sensitivity, specificity, and positive predictive value (PPV) were calculated.WHO standards had the lowest specificity for identifying short stature in India and Indonesia. BMI-for-age charts using WHO Growth Reference (2007) had lower sensitivity and higher specificity for metabolic risk. Local references showed lower stunting and higher overweight or obesity prevalence. International standards overestimated stunting and underestimated obesity, leading to misclassification and missed cases of metabolic risk. Funding None.

Adult height improved over decades in patients with X-linked hypophosphatemia: a cohort study. Eur J Endocrinol 2023; 189:469-475. [PMID: 37831782 DOI: 10.1093/ejendo/lvad144] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Revised: 07/28/2023] [Accepted: 09/07/2023] [Indexed: 10/15/2023]
Abstract
OBJECTIVES The aim of this study is to analyze height after cessation of growth (final height [FH]) and its evolution over the last decades in X-linked hypophosphatemia (XLH) patients in France, as the data on natural history of FH in XLH are lacking. DESIGN We performed a retrospective observational study in a large cohort of French XLH patients with available data on FH measurements. MATERIALS AND METHODS We divided patients into 3 groups according to their birth year: group 1 born between 1950 and 1974, group 2 born between 1975 and 2000, and group 3 born between 2001 and 2006, respectively, and compared their FHs. RESULTS A total of 398 patients were included. Mean FHs were the following: for group 1, -2.31 ± 1.11 standard deviation score (SDS) (n = 127), 156.3 ± 9.7 cm in men and 148.6 ± 6.5 cm in women; for group 2, -1.63 ± 1.13 SDS (n = 193), 161.6 ± 8.5 cm in men and 153.1 ± 7.2 cm in women; and for group 3, -1.34 ± 0.87 SDS (n = 78), 165.1 ± 5.5 cm in men and 154.7 ± 6 cm in women. We report a significant increase in mean FH SDS over 3 generations of patients, for both men and women (P < .001). Final height SDS in male (-2.08 ± 1.18) was lower than in female (-1.70 ± 1.12) (P = .002). CONCLUSION The FH of XLH patients in France increased significantly over the last decades. Even though men's FHs improved more than women's, men with XLH remain shorter reflecting a more severe disease phenotype. While the results are promising, most patients with XLH remain short leaving room for improvement.

Abstract
Purpose Infant regurgitation is associated with other functional gastrointestinal disorders and signs and symptoms that have a major impact on the quality of life of infants and their families. This study evaluated the safety, tolerance, and real-world effectiveness of an anti-regurgitation formula containing locust bean gum (LBG), prebiotics, and postbiotics to alleviate digestive symptoms beyond regurgitation. Methods This 3-month study involved infants with regurgitation requiring the prescription of an anti-regurgitation formula according to usual clinical practice. Outcomes included evaluation of the evolution of stool consistency and frequency; occurrence of colic, constipation, and diarrhea; and assessment of regurgitation severity. Infant crying, parental assessment of infant well-being, and parental satisfaction with the stool consistency were also evaluated. Results In total, 190 infants (average age: 1.9±1.1 months) were included. After three months, stool frequency and consistency remained within the normal physiological range, with 82.7% of infants passing one or two stools per day and 90.4% passing loose or formed stools. There was no significant increase in the number of infants with diarrhea, whereas a decrease was observed in the number of infants with constipation after 1 month (p=0.001) and with colic after both 1 and 3 months (p<0.001). Regurgitation severity and crying decreased and parental satisfaction with stool consistency, formula acceptability, infant well-being, and sleep quality increased. Monitoring of adverse events did not reveal any safety concerns. Conclusion Formulas containing LBG, prebiotics, and postbiotics were well tolerated and provided an effective strategy for managing infant regurgitation and gastrointestinal discomfort.

Abstract
Evidence supports that growth trajectory during infancy has a major impact on body composition. We aimed to examine body composition in children born small for gestational age (SGA) or appropriate for gestational age (AGA) adjusted for postnatal growth velocity. We enrolled 365 children, 75 SGA and 290 AGA, aged 7 to 10 years, examining anthropometrics, skinfold thickness, and body composition using bioelectrical impedance analysis. Growth velocity was defined as rapid or slow (weight gain > or <0.67 z-scores, respectively). Gestational age, sex, delivery mode, gestational diabetes, hypertension, nutrition, exercise, parental body mass index (BMI), and socioeconomic status were considered. At a mean of 9 years of age, SGA compared with AGA-born children, had significantly lower lean mass. BMI was negatively associated with SGA status (beta = 0.80, P = .046), after adjusting for birth weight, delivery mode, and breastfeeding. The lean mass index was negatively associated with SGA status (beta = 0.39, P = .018), after adjusting for the same factors. SGA-born participants with slow growth velocity had significantly lower lean mass in comparison to AGA-born counterparts. SGA-born children with rapid compared with those with slow growth velocity had significantly higher absolute fat mass. BMI was negatively associated with a slow postnatal growth pattern (beta = 0.59, P = .023), and the lean mass index was negatively associated with a slow postnatal growth pattern (beta = 0.78, P = .006), after adjusting for the same factors. In conclusion, SGA-born children presented a lower lean mass in comparison to AGA-born counterparts, whereas BMI and lean mass index were negatively associated with slow postnatal growth velocity.

Abstract
BACKGROUND Elevated body mass index (BMI) and rapid growth in early childhood are important predictors of obesity risk. The association between maternal preconception BMI and child growth rates is unclear. OBJECTIVES To assess the association between measured maternal preconception BMI and child age- and sex- standardized WHO BMI z-score (zBMI) growth rates and mean zBMI, in children aged 0-10 years old. METHODS A longitudinal cohort study was conducted with children (n = 499) enrolled in The Applied Research Group for Kids (TARGet Kids!) primary care practice-based research cohort. Maternal BMI was measured during the preconception period, defined as the 2 years prior to pregnancy. Repeated measures of child weight and height were obtained between 0 and 10 years of age. Linear mixed models were used to evaluate the association between maternal BMI and child zBMI growth rates and mean zBMI. RESULTS Maternal preconception BMI was associated with child zBMI growth rate during some growth periods, with the strongest association from age 0 to 4 months; a 5 kg/m2 higher maternal BMI was associated with 0.031 zBMI SD unit/mo higher growth rate (p = 0.004), and 0.186 SD unit higher mean child zBMI (p = 0.0002). CONCLUSIONS Maternal preconception BMI was associated with growth rate and mean zBMI in early childhood. The preconception period may be an important target for health interventions to promote healthy child growth rate and weight outcomes.

[PMID: 36729422 PMCID: PMC10013152 DOI: 10.1097/mpg.0000000000003683] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Accepted: 10/27/2022] [Indexed: 02/03/2023]
Abstract
OBJECTIVES PERFUSE is a non-interventional study of 1233 patients [inflammatory rheumatic disease, n = 496; inflammatory bowel disease (IBD), n = 737] receiving infliximab (IFX) biosimilar SB2 therapy. This analysis describes response to treatment and persistence on SB2 for up to 12 months in pediatric IBD patients (n = 126). METHODS Pediatric IBD patients with Crohn disease (CD) or ulcerative colitis (UC), either naïve or switched from originator IFX, who started SB2 in routine practice after September 2017 were eligible. Data were captured for 12 months following SB2 initiation. Disease activity was measured using C-reactive protein (CRP) levels and the Harvey-Bradshaw Index or Pediatric Ulcerative Colitis Activity Index for CD and UC patients, respectively. Body mass index and height z scores were used to assess patient growth between initiation (M0) and month 12 (M12). RESULTS One hundred twenty-six pediatric IBD patients were included (102 CD patients, 51 naïve and 51 switched; 24 UC patients, 9 naïve and 15 switched). Naive patients' disease scores decreased between M0 and M12. CRP measurements also decreased in naïve CD patients. Switched patients' disease scores and CRP levels remained stable between M0 and M12. Height z scores improved significantly over the course of the treatment for all groups except for naïve UC patients. CONCLUSIONS SB2 provides effective disease control for naïve and switched pediatric patients. Clinical remission rates improved in naïve patients and no loss of control was observed in switched patients after 1 year. Growth failure is not observed in IBD patients under SB2 treatment.

Paternal BMI in the preconception period, and the association with child zBMI. Int J Obes (Lond) 2023; 47:280-287. [PMID: 36737513 DOI: 10.1038/s41366-023-01261-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 01/10/2023] [Accepted: 01/17/2023] [Indexed: 02/05/2023]
Abstract
BACKGROUND Rapid growth and excess weight in early childhood are associated with obesity risk. While maternal preconception BMI has been identified as a potential risk factor, the role of paternal preconception BMI is less clear. OBJECTIVES To examine the association between paternal preconception BMI and age- and sex-standardized WHO BMI z-score (zBMI) growth rates, zBMI, and weight status, in 0- to 10-year-old children. To determine whether these associations differed by child sex and maternal preconception weight status. METHODS A longitudinal cohort study was conducted through The Applied Research Group for Kids (TARGet Kids!). Children (n = 218) underwent repeated measures of height and weight from birth to 10 years old. Piecewise linear mixed models were used to assess the association between paternal preconception BMI and child zBMI growth rates (zBMI SD units/month) between 0, 4, 30, 48 and 120 months of age. Linear mixed models were used to examine the association with child zBMI, and logistic generalized estimation equations (GEE) were used to assess the association with child weight status. Child sex and maternal preconception weight status were tested as effect modifiers. RESULTS Paternal preconception BMI was associated with child zBMI growth rate, mean zBMI and weight status in boys, but not girls. A 5 kg/m2 higher paternal preconception BMI was associated with approximately 0.01 zBMI SD unit/month higher growth rate for boys born to mothers with preconception overweight. Higher paternal BMI was associated with higher mean zBMI and increased odds of overweight and obesity in boys, with greater effects seen when mothers had preconception overweight compared to normal weight. CONCLUSION Paternal preconception BMI was associated with child zBMI growth rate, zBMI and weight status in boys, with greater effects when the biological mother had preconception overweight or obesity. Further understanding of sex differences in paternal preconception weight effects in children is needed.

Eur J Pediatr 2023; 182:661-668. [PMID: 36445515 PMCID: PMC9899173 DOI: 10.1007/s00431-022-04723-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2022] [Revised: 09/13/2022] [Accepted: 11/17/2022] [Indexed: 11/30/2022]
Abstract
This study aims to examine if small for gestation age (SGA) status is correlated with alterations in body composition at prepuberty, independently of other factors, comparing SGA-born children with appropriate for gestational age (AGA)-born children. We examined anthropometrics, waist circumference, body mass index (BMI), six skinfold thickness, and body composition using the method of bioelectrical impedance in 636 children aged 7 to 10 years. We also considered age, gender, birth mode, mother's age, prepregnancy weight, weight gain during pregnancy, social status, parental BMI, type of feeding, and daily exercise. We examined 636 children at a mean age of 9 years: 106 SGA-born and 530 AGA-born children. SGA as compared to AGA-born children had a lower BMI z-score (0.26 ± 0.89 kg/cm2 vs 0.46 ± 0.84 kg/cm2, p < 0.050) and a lower lean mass, although that was not statistically significant (24.0 ± 6.6 kg vs 25.6 ± 6.4 kg, p < 0.100). SGA-born children presented no difference in waist circumference or fat mass in comparison to children born AGA. Logistic regression analysis revealed a strong independent negative association between SGA status and BMI (beta = - 2.33, OR = 0.70 p = 0.019) and SGA status and lean mass (beta = - 2.43, OR = 0.95 p = 0.010). Conclusion: Our findings suggest that SGA-born children had a lower BMI as compared to AGA-born subjects, whereas SGA status was negatively associated with BMI and lean mass. What is Known: • Deviant birth weight for gestation has been associated with an increased risk of childhood adiposity. • Evidence remains scarce on whether small for gestational age status affects body composition and obesity later in childhood. What is New: • Among school-aged children, small for gestational age subjects had a lower body mass index as compared to appropriate for gestational age counterparts, whereas small for gestational age status was negatively associated with body mass index and lean mass. • A meticulous observation is needed during childhood in children born with deviant birth weight.

[PMID: 35372644 PMCID: PMC8965158 DOI: 10.1016/j.bonr.2022.101524] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/20/2021] [Revised: 03/22/2022] [Accepted: 03/23/2022] [Indexed: 11/26/2022] Open
Abstract
Objective Faciocraniosynostoses (FCS) are malformations affecting the development of the bones of the skull and face, due to the premature closure of one or more craniofacial sutures, mostly secondary to activating Fibroblast Growth Factor Receptor (FGFR) 1–3 mutations. Gain-of-function FGFR3 mutations are also responsible for various conditions referred to as osteochondrodysplasia (OCD), characterized by structural and functional abnormalities of growth plate cartilages. We hypothesized that patients with FGFR-related faciocraniosynostoses may present extra-cranial growth anomalies. Study design We retrospectively collected height and weight data from a cohort of 70 patients. Included patients were admitted for FGFR-related FCS between 2000 and 2021 at the Craniofacial Unit of Necker – Enfants Malades University Hospital in Paris, France. Results We showed that FGFR-related faciocraniosynostoses had significantly reduced heights and weights relative to controls, and that two specific time periods (1–3 years and > 8 years of age) were associated with lower height and weight values. Four patients had received growth hormone treatment but remained below normal values for growth in height and weight. Conclusions Patients with FGFR-related faciocraniosynostoses have clinically significant extra-cranial anomalies which are not currently investigated and managed in usual protocols; these patients could benefit from a systematic pre-pubertal endocrine assessment. More generally, our results extend the scope of extracranial anomalies in FGFR-related faciocraniosynostoses and support the hypothesis that all conditions with activating FGFR mutations affect both membranous ossification and long bones. FGFR mutations can cause syndromic faciocraniosynostoses (FCS) and are also responsible for osteochondrodysplasia. Patients with FCS present with significant delays in development compared to the standard French population. Patients with FCS could benefit from a systematic pre-pubertal endocrine assessment and hormonotherapy but more data is required to establish guidelines. FCS and achondroplasia both affect membranous and endochondral ossification processes.

Abstract
Background The monitoring of head circumference (HC) is essential to early detect any conditions affecting its growth in early childhood. A positive secular trend and regional specificities in HC suggested the need to provide updated national HC reference growth charts. Methods We extracted all growth data collected from 42 primary-care physicians from across the French metropolitan territory who used the same electronic medical-records software. We selected HC measurements up to age five years for all children who were born after 1990 with birth weight > 2500 g. We derived new HC growth charts by using Generalized Additive Models for Location, Scale and Shape, then externally validated them until 30 months of age by comparison with the national population-based Étude Longitudinale Française depuis l'Enfance (ELFE) birth cohort and compared them to previous French and WHO growth charts. Findings With 973,869 HC measurements from 157,762 children, new calibrated HC growth charts from birth to age five years were generated. The new HC growth charts showed good external fit by comparison with the ELFE birth cohort. As compared with the new HC growth charts, the previous French and WHO growth charts mean HC z-scores were, respectively, -0.4 and -0.6 SD for girls and -0.2 and -0.6 SD for boys. Interpretation We produced and validated national calibrated HC growth charts by using a novel big-data approach applied to data routinely collected in clinical practice. Comparison with previous French and WHO growth charts confirmed a positive secular trend since the 1960s and regional specificities.

Abstract
Anthropometric evaluation of children is among the most vital and widely used instruments of public health and clinical medicine. Anthropometry is used for establishing norms, identifying variations, and monitoring development. Yet the accurate assessment of physical growth and development of children remains a perpetually beleaguering subject. This paper focuses on the evolution of anthropometry as a science and its associated measurements, indices, indicators, standards, references, and best practices. This paper seeks to clarify aspects of the assessment of child growth, explores the historical trajectory of the study of anthropometry and its contemporary limitations, and contributes to the debate surrounding references and standards, and the applicability of international anthropometric standards to an individual's health. Among its findings is a surprisingly nonlinear and contested record of events, up to and including leading contemporary practices and datasets. It contextualizes the legacy of child malnutrition studies in a broad framework, including the linkage between the early eugenics movement and contemporary notions of a "normal" child, the interpersonal and intuitional competition to become the preeminent child growth authority, the obfuscated distinction between reference growth charts and standards of growth, and the hidden consequences of universal growth standards that no longer reflect any observable populations.

Abstract
BACKGROUND This study focused on comparing the applicability and efficacy of the World Health Organization (WHO) growth standards and the China growth charts in diagnosing malnutrition and indicating nutritional interventions in preterm infants. METHODS Six hundred and eighty-three preterm infants were involved and their anthropometric data were collected. The proportion of weight and head circumference less than the 10th percentile (P10 ), weight less than the 25th percentile (P25 ), and weight for length greater than the 90th percentile (P90 ) identified by the WHO growth standards and the China growth charts were compared. RESULTS At corrected age (CA) 1 ~< 2 months (m), the proportion of head circumference P90 assessed by the WHO growth standards was greater than that assessed by the China growth charts. CONCLUSIONS Compared with the China growth charts, the WHO growth standards can further reduce the number of diagnoses of abnormal physical growth, are more helpful in avoiding overnutrition interventions, and are more sensitive in the early detection of delayed head circumference growth.

Abstract
Objective To study the link between a high body mass index (BMI) in childhood and the occurrence of pediatric-onset multiple sclerosis (POMS) and to compare, within the MS population, the clinical-radiologic-biological characteristics, according to BMI. Methods A case-control study comparing BMI data of 60 patients with POMS (39 girls and 21 boys) at Bicêtre Hospital with that of 113 non-neurologic controls NNCs (68 girls and 45 boys) and 18,614 healthy controls HCs (9,271 girls and 9,343 boys) was performed. Crude BMI (cBMI), residual BMI (rBMI = measured BMI − expected BMI for age), z-score (rBMI/SD), and adult equivalent categories (International Obesity Task Force ≥25 = overweight, ≥30 = obese) were assessed. Results In boys, cBMI and rBMI were significantly higher in patients with POMS compared with NNCs (cBMI: +2.9; rBMI: +2.95, p < 0.01) and HCs (cBMI: +2.04, p < 0.01). In girls, cBMI or rBMI did not differ between POMS and NNCs patients (cBMI p = 0.4; rBMI p = 0.44) but with HCs (cBMI +0.99, p < 0.01). CSF inflammatory markers increased with BMI in prepubertal patients (p < 0.01), whereas vitamin D level at diagnosis was lower in boys with higher BMI (p = 0.016). Increased BMI was not associated with clinical and radiologic disease characteristics. Conclusions Overweight and obesity are more frequently observed at diagnosis, particularly in boys with POMS compared with non-neurologic controls and French HCs. Moreover, BMI is related to initial inflammation in the CSF in prepubertal patients with POMS suggesting an interaction between excess body fat, sexual hormones, and POMS occurrence.

Abstract
BACKGROUND Although manganese (Mn) is an essential nutrient, recent research has revealed that excess Mn in early childhood may have adverse effects on neurodevelopment. METHODS We estimated daily total Mn intake due to breast milk at average body weights by reviewing reported concentrations of breast milk Mn and measurements of body weight and breast milk intake at 3 weeks, 4.25 months, 7 months, and 18 months. We compared these figures to the Mn content measured in 44 infant, follow-up, and toddler formulas purchased in the United States and France. We calculated Mn content of formula products made with ultra-trace elemental analysis grade water (0 μg Mn/L) and with water containing 250 μg Mn/L, a concentration which is relatively high but less than the World Health Organization Health-based value of 400 μg Mn/L or the United States Environmental Protection Agency Health Advisory of 350 μg Mn/L. RESULTS Estimated mean daily Mn intake from breast milk ranged from 1.2 μg Mn/kg/day (3 weeks) to 0.16 μg Mn/kg/day (18 months), with the highest intakes at the youngest age stage we considered, 3 weeks. Estimated daily Mn intake from formula products reconstituted with 0 μg Mn/L water ranged from 130 μg Mn/kg/day (3 weeks) to 4.8 μg Mn/kg/day (18 months) with the highest intakes at 3 weeks. Formula products provided 28-520 times greater than the mean daily intake of Mn from breast milk for the 4 age stages that we considered. Estimated daily Mn intake from formula products reconstituted with water containing 250 μg Mn/L ranged from 12 μg Mn/kg/day to 170 μg Mn/kg/day, which exceeds the United States Environmental Protection Agency Reference Dose of 140 μg Mn/kg/day for adults. CONCLUSIONS Mn deficiency is highly unlikely with exclusive breast milk or infant formula feeding, but established tolerable daily intake levels for Mn may be surpassed by some of these products when following labeled instructions.

Abstract
Background World Health Organization (WHO) growth standards for children aged 0 to 5 years describe growth under optimal conditions and were adopted for use in Canada in 2012. We are seeking to validate these charts in a well-characterized, longitudinal cohort of healthy, Canadian youngsters, assess tracking over time, and evaluate the prognostic implications of early growth. Methods Data from 2,795 mother-infant dyads from the CHILD birth cohort were classified by feeding modality at 6 months as exclusively breastfed, partially breastfed, or formula-fed. WHO z-scores (z) were calculated at birth, 3 months, 1 year, and 3 years. Receiver operator characteristics (ROC) assessed the predictive performance of early weight (WT), weight-for-length (WfL), or body mass index (BMI) z-scores for overweight/obesity at 3 years. Results Compared to WHO standards, Canadian children at birth had lower median WfLz (-0.73) and BMIz (-0.29), with more positive scores by 3 years (WfLz=BMIz=0.58). At both 1 and 3 years, formula feeding was associated with higher scores than breastfeeding, even after regression adjustment for covariates. Head circumference z-score was typically positive at all times and regardless of feeding modality. At 1 year, ROC area under the curve was 0.79 for WTz, WfLz, and BMIz, and BMIz>0.88 identified children with increased risk of overweight/obesity (BMIz >2) at age 3 years (20.3% versus 3.0%, P<0.001). Conclusions Compared to WHO growth charts, Canadian children at 3 years show an upward shift in BMIz and WfLz, particularly when formula-fed. Infant growth parameters may identify infants with increased risk of overweight/obesity at age 3 years; early recognition may allow targeting infants at higher risk.

Health Status of French Young Patients with Inborn Errors of Metabolism with Lifelong Restricted Diet. J Pediatr 2020; 220:184-192.e6. [PMID: 32145964 DOI: 10.1016/j.jpeds.2020.01.059] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2019] [Revised: 12/26/2019] [Accepted: 01/28/2020] [Indexed: 12/26/2022]
Abstract
OBJECTIVE To describe the health status of young patients affected by inborn errors of metabolism that require adherence to a restricted diet (IEMRDs) and to describe and compare their self- and proxy (parent)-reported quality of life (QoL) with reference values. STUDY DESIGN A cross-sectional study was conducted in 2015-2017 in patients affected by IEMRDs (except phenylketonuria) younger than 18 years. Data collection was based on medical records, clinical examinations, parents' and children's interviews, and self-reported questionnaires. Measurements included clinical and healthcare data, child and family environment data, and self- and proxy (parent)-reported QoL. RESULTS Of the 633 eligible participants, 578 were recruited (50.3% boys; mean age: 8.7 years); their anthropometric status did not differ from the general population. Approximately one-half of them had at least 1 complication of the disease. Their self-reported global QoL did not differ from that of the general population. However, relations with friends and leisure activities QoL domains were negatively impacted, whereas relations with medical staff, relations with parents, and self-esteem QoL domains were positively impacted. Their proxy (parent)-reported QoL was negatively impacted. CONCLUSIONS Young patients affected by IEMRDs present a high rate of clinical complications. Although their proxy (parent)-reported QoL was negatively impacted, their self-reported QoL was variably impacted (both positively and negatively). These results may inform counseling for those who care for affected patients and their families.

Abstract
AIM To review orofacial disabilities and their consequences in children with Moebius syndrome (MBS). METHOD We retrospectively analysed the records of 32 patients (21 males, 11 females) with non-progressive bilateral facial and abducens palsies who had been examined before 6 months of age. RESULTS All facial muscles were severely involved in 17 patients; in the 15 others, partial movements were found in the lower face. Most patients (n=24) were unable to smile. Patients frequently presented with congenital trismus (n=20) and drooling (n=18). Additional palsies involved cranial nerves IX and X (n=18) and XII (n=25). Sucking was absent or weak in 30 patients; swallowing was impaired in 25. During the first month of life, feeding disorders were graded as severe/moderate in 25. Respiratory complications occurred in 17. Severe feeding disorders were associated with congenital trismus (p=0.01) and with cranial nerve IX and X palsy (p=0.01). Growth failure between 1 and 6 months of age, followed by catch-up growth between 6 and 12 months, was observed in 20 patients. Between 2 and 5 years of age, 25 out of 32 patients attained normal oral diet and 28 out of 29 showed normal growth. INTERPRETATION Children with MBS frequently require adjusted therapeutic options to prevent failure to thrive. Congenital trismus, cranial nerve IX and X palsy, and laryngeal-tracheal dysfunctions are predictors of severe feeding disorders. WHAT THIS PAPER ADDS Moebius syndrome frequently induces reduced oral intake and early failure to thrive. Normal oral diet and growth parameters are attained at 2 to 5 years of age. Congenital trismus, pharyngeal palsy, and laryngeal disorders predict dysphagia.

Abstract
In population exposed to cardiovascular risk, aortic stiffness is an important marker which is assessed by carotid-to-femoral pulse wave velocity (PWV). In childhood, the validated applanation tonometer SphygmoCor® can be used to measure PWV, but is limited in routine practice by the child's cooperation and operator's experience. An alternative device, the pOpmètre® is validated in adults and rapidly measures finger-to-toe PWV using 2 oxymeter-like sensors. The aim of this study is to validate the pOpmètre® device in children aged between 4 and 8 years. We compared simultaneous PWV measurements of the two devices, SphygmoCor® and pOpmètre®, in a training group, using the Bland-Altman method. Then we proposed an algorithm to correct pOpmètre® PWV (PWVpop). Finally, we validated this new algorithm in a validation group of children using the Bland-Altman method. This prospective study enrolled 26 children in the training group. Mean PWVpop was 3.919 ± 0.587 m/s and mean SphygmoCor® PWV was 4.280 ± 0.383 m/s, with a difference of -0.362(CI95%(-0.546;-0.178)) m/s. A new algorithm was defined using transit time (TTpop): corrected PWVpop (m/s) = 0.150/TTpop(s) + 1.381*Height(m) + 1.148. We enrolled 24 children in the validation group. Mean corrected PWVpop was 4.231 ± 0.189 m/s and mean SphygmoCor® PWV was 4.208 ± 0.296 m/s with a corrected difference of 0.023(CI95%(-0.086;0.131)) m/s. With this algorithm correction, we found an agreement between PWV measured by the SphygmoCor® and the pOpmètre®, with a difference of less than 10%. Using this algorithm, the pOpmètre® could be used in clinical or research practice in young children exposed to cardiovascular risk. (This study was registered as NCT02991703).

Abstract
Background: Growth charts are an important method for evaluating a child's health, growth, and nutritional status. Objective: To establish Lambda-Mu- Sigma (LMS) and Z score references for assessment of growth and nutritional status in Egyptian school children and adolescents. Methods: A total of 34,822 Egyptian school children and adolescents from 5 to 19 years were enrolled in a cross sectional randomized study from December 2017 to November 2019 to create LMS and Z score references for weight, height and body mass index (BMI) corresponding to ages. They were selected from different districts in Egypt. Apparent Healthy children with good nutritional history and not suffering from any chronic diseases were included in the study. Results: Egyptian children of both sexes (54.3% boys and 45.7 % girls) from 5 to 19 years old were studied. Then LMS and Z scores for weight for age, height for age, BMI for age of both sexes were represented in detailed tables and graphs. There was no statistically significant difference between the Egyptian Z score charts and the reference values of WHO for weight, height and BMI corresponding to age (P > 0.05). Conclusion: This is the first national reference for growth and nutritional assessment using LMS and Z score charts in Egyptian school children and adolescents, this tool is essential for healthcare and research.

A big-data approach to producing descriptive anthropometric references: a feasibility and validation study of paediatric growth charts. LANCET DIGITAL HEALTH 2019; 1:e413-e423.

Abstract
BACKGROUND Both national and WHO growth charts have been found to be poorly calibrated with the physical growth of children in many countries. We aimed to generate new national growth charts for French children in the context of huge datasets of physical growth measurements routinely collected by office-based health practitioners. METHODS We recruited 32 randomly sampled primary care paediatricians and ten volunteer general practitioners from across the French metropolitan territory who used the same electronic medical records software, from which we extracted all physical growth data for the paediatric patients, with anonymisation. We included measurements from all children born from Jan 1, 1990, and aged 1 month to 18 years by Feb 8, 2018, with birthweight greater than 2500 g, to which an automated process of data cleaning developed to detect and delete measurement or transcription errors was applied. Growth charts for weight and height were derived by using generalised additive models for location, scale, and shape with the Box-Cox power exponential distribution. We compared the new charts to WHO growth charts and existing French national growth charts, and validated our charts using growth data from recent national cross-sectional surveys. FINDINGS After data cleaning, we included 1 458 468 height and 1 690 340 weight measurements from 238 102 children. When compared with the existing French national and WHO growth charts, all height SD and weight percentile curves for the new growth charts were distinctly above those for the existing French national growth charts, as early as age 1 month, with an average difference of -0·75 SD for height and -0·50 SD for weight for both sexes. Comparison with national cross-sectional surveys showed satisfactory calibration, with generally good fit for children aged 5-6 years and 10-11 years in height and weight and small differences at age 14-15 years. INTERPRETATION We successfully produced calibrated paediatric growth charts by using a novel big-data approach applied to data routinely collected in clinical practice that could be used in many fields other than anthropometry.

Abstract
INTRODUCTION Short stature is a family concern, and is a common reason for consultations in paediatrics. Growth charts are an essential diagnostic tool. The objective of this study is to evaluate the impact of changing reference charts in the diagnosis of short stature in a health area. SUBJECTS AND METHODS A population-based-cross-sectional-descriptive-study was performed in which the height of children of 4, 6, 10 and 13 years-old were compared with the growth charts of the Fundación Orbegozo 2004 Longitudinal and 2011. The prevalence of short stature and the 3rd percentile of the study sample were calculated. RESULTS There were 12,256 valid records (89% of the population). The prevalence of short stature increased at all ages with the change in the growth charts, with differences of prevalence of 3.6% (95% CI: 2.8 to 4.5) at 4 years; 1.8% (95% CI: 1.3 to 2.3) at 6 years; 2.8% (95% CI: 2.2 to 3.4) at 10 years, and 1.4% (95% CI: 0.8 to 1.9) at 13 years. In absolute numbers, it went from 58 diagnoses of short stature with the 2004 Longitudinal charts (34 boys and 24 girls) to 352 with the 2011 (155 boys and 197 girls). CONCLUSIONS The change in reference growth charts has increased by 6-fold the number of diagnoses of short stature. The pathological condition found in the cases diagnosed with the 2011 growth charts that had not been diagnosed with the previous charts will allow us to evaluate the suitability of the change.

Association of accelerated body mass index gain with repeated measures of blood pressure in early childhood. Int J Obes (Lond) 2019; 43:1354-1362.

Abstract
Background/objectives We examined the association for rates of age- and sex-standardized body mass index (zBMI) gain between 0–3, 3–18, and 18–36 months with BP in children at 36–72 months of age. Methods We collected repeated measures of zBMI and BP in 2502 children. zBMI was calculated using the World Health Organization standards. Each child’s zBMI at birth and rates of zBMI gain in each period from birth to 36 months were estimated using linear spline multilevel models. Generalized estimating equations were used to determine whether zBMI at birth and zBMI gain between 0–3, 3–18, and 18–36 months were each associated with repeated measures of BP at 36–72 months of age. We sequentially conditioned on zBMI at birth and zBMI gain in each period prior to each period tested, as covariates, and adjusted for important socio-demographic, familial, and study design covariates. We examined whether these associations were modified by birthweight or maternal obesity, by including interaction terms. Results After adjusting for all covariates and conditioning on prior zBMI gains, a 1 standard deviation unit faster rate of zBMI gain during 0–3 months, (β = 0.59 mmHg; 95% CI 0.31, 0.86) and 3–18 months (β = 0.74 mmHg; 95% CI 0.46, 1.03) were each associated with higher systolic BP at 36–72 months. No significant associations were observed, however, for zBMI at birth or zBMI gain in the 18–36 month growth period. zBMI gains from 0–3 and 3–18 months were also associated with diastolic BP. Birthweight significantly modified the relationship during the 3–18 month period (p = 0.02), with the low birthweight group exhibiting the strongest association for faster rate of zBMI gain with higher systolic BP (β = 1.31 mmHg; 95% CI 0.14, 2.48). Conclusions Given that long-term exposure to small elevations in BP are associated with subclinical cardiovascular disease, promoting interventions targeting healthy growth in infancy may be important.

Abstract
Short stature remains the most common reason for referral to a pediatric Endocrinologist and its management remains a challenge. One of the main controversies is the diagnosis of idiopathic short stature and the role of new technologies for genetic investigation of children with inadequate growth. Complexities in management of children with short stature includes selection of who should receive interventions such as recombinant human growth hormone, and how should this agent dose be adjusted during treatment. Should anthropometrical data be the primary determinant or should biochemical and genetic data be used to improve growth response and safety? Furthermore, what is considered a suboptimal response to growth hormone therapy and how should this be managed? Treatment of children with short stature remains a "hot" topic and more data is needed in several areas. These issues are reviewed in this paper.

Abstract
Background Accelerated postnatal growth is an important predictor for obesity risk. It is unknown whether early-life obesity-related risk factors affect body mass index (BMI) growth rates during distinct growth periods from early infancy through preschool years. Objective We examined whether breastfeeding duration, maternal BMI, and birth weight are associated with growth trajectories of age- and sex-standardized WHO BMI z scores (zBMIs) in young children. Design Children (n = 5905) in The Applied Research Group for Kids (TARGet Kids!) prospective cohort study underwent repeated measures of weight and length or height from birth to 10 y of age. Piecewise linear mixed models were used to determine whether zBMI growth rates differ for each risk factor during periods of growth between birth and 1, 3, 18, 36, and 72 mo of age. Results Children who were breastfed <6 mo compared with ≥6 mo showed a higher growth rate between 1-3 and 3-18 mo, resulting in higher standardized BMIs (zBMIs) of +0.24, +0.12, and +0.19 at 18, 36, and 72 mo, respectively. Maternal BMI (in kg/m2) ≥30 compared with <30 resulted in higher growth rates between 1-3 and 36-72 mo and higher zBMIs of +0.22, +0.14, +0.18, and +0.41 at 3, 18, 36, and 72 mo, respectively. Infants weighing <2.5 kg at birth (compared with 2.5-4 kg) experienced higher growth rates between 1-3 and 3-18 mo but had lower zBMIs at all time points (zBMI: -1.45 to -0.21). Infants weighing ≥4 kg at birth (compared with 2.5-4 kg) had significantly lower growth rates in the first 3 mo but higher zBMIs at all time points (zBMI: +1.16 to +0.27). Conclusion Differences in zBMI growth rates by breastfeeding duration, maternal BMI, and birth weight are seen in early infancy and contribute to differences in zBMI, which persist into midchildhood. This trial was registered at www.clinicaltrials.gov as NCT01869530.

Abstract
Objectives This study aimed to compare reference anthropometric measures of Omani neonates with the international standard growth charts of the World Health Organization (WHO) in order to determine the appropriateness of these growth charts to assess the growth of Omani neonates. Methods This cross-sectional study included all healthy full-term Omani neonates born between November 2014 and November 2015 at the Sultan Qaboos University Hospital, Muscat, Oman. Birth weight, length and head circumference measurements were identified and compared to those of the 2006 WHO growth charts. Results A total of 2,766 full-term neonates were included in the study, of which 1,401 (50.7%) were male and 1,365 (49.3%) were female. Mean birth weights for Omani males and females were 3.16 ± 0.39 kg and 3.06 ± 0.38 kg, respectively; these were significantly lower than the WHO standard measurements (P <0.001). Similarly, the mean head circumferences of Omani males and females (33.8 ± 1.27 cm and 33.3 ± 1.26 cm, respectively) were significantly lower than those reported in the WHO growth charts (P <0.001). In contrast, mean lengths for Omani males and females (52.0 ± 2.62 cm and 51.4 ± 2.64 cm, respectively) were significantly higher than the WHO standard measurements (P <0.001). Conclusion The WHO growth charts might not be appropriate for use with Omani neonates; possible alternatives should therefore be considered, such as national growth charts based on local data.

Abstract
BackgroundTo describe the growth patterns of children affected by Marfan syndrome (MFS) compared with those of unaffected children and to create growth charts.MethodsAn observational study of children referred to the French National MFS Reference Centre. A total of 259 children carrying an FBN1 gene mutation and fulfilling Ghent 1 criteria (MFS group) and 474 mutation-negative sibling controls (non-MFS group) were evaluated. Both groups were compared with French-accepted reference nomograms (Reference group).ResultsBoys and girls from the MFS group were significantly taller than those in the non-MFS group and in the reference group at all ages (P<0.0001). But, MFS children's overgrowth reduced with age. At 17 years of age, the mean height (MFS vs. non-MFS) was 191.2±8.4 cm (+2.9 SD) vs. 182.9±8.1 (+1.6 SD) for boys and 178.3±7.6 cm (+2.7 SD) vs. 169.5±6.8 (+1.2 SD) for girls, respectively. By contrast, the mean BMI of children in the MFS group was similar to those in the non-MFS group and inferior to the values of French general population, evolving around -1 SD.ConclusionGrowth patterns differ in patients with an FBN1 mutation. Knowing the growth parameters should allow physicians to better counsel patients and detect the associated diseases. The provided curves could also help to predict the final height.

Abstract
A probabilistic and interdisciplinary risk-benefit assessment (RBA) model integrating microbiological, nutritional, and chemical components was developed for infant milk, with the objective of predicting the health impact of different scenarios of consumption. Infant feeding is a particular concern of interest in RBA as breast milk and powder infant formula have both been associated with risks and benefits related to chemicals, bacteria, and nutrients, hence the model considers these three facets. Cronobacter sakazakii, dioxin-like polychlorinated biphenyls (dl-PCB), and docosahexaenoic acid (DHA) were three risk/benefit factors selected as key issues in microbiology, chemistry, and nutrition, respectively. The present model was probabilistic with variability and uncertainty separated using a second-order Monte Carlo simulation process. In this study, advantages and limitations of undertaking probabilistic and interdisciplinary RBA are discussed. In particular, the probabilistic technique was found to be powerful in dealing with missing data and to translate assumptions into quantitative inputs while taking uncertainty into account. In addition, separation of variability and uncertainty strengthened the interpretation of the model outputs by enabling better consideration and distinction of natural heterogeneity from lack of knowledge. Interdisciplinary RBA is necessary to give more structured conclusions and avoid contradictory messages to policymakers and also to consumers, leading to more decisive food recommendations. This assessment provides a conceptual development of the RBA methodology and is a robust basis on which to build upon.

Abstract
The problem of overweight and obesity in children and adolescents has been noted in many different countries. The aim of this study was to evaluate the differences in the percentage occurrence of overweight and obesity in Polish children depending on the criteria used, and to evaluate the usefulness of the Polish national database. The study sample comprised 3405 children aged 5-14 years (1674 girls and 1731 boys) from the city of Kraków, Poland, in 2009-2010. The BMI of each child was calculated and classified as overweight or obese according to three different reference BMI cut-offs: the International Obesity Task Force (IOTF), the Centers for Disease Control and Prevention (CDC) and the Polish 2010 standard. To assess the statistical significance of the differences between these three applied reference datasets, a comparison of two proportions was performed and Cohen's kappa coefficient calculated. The prevalences of overweight were 15%, 11.3% and 9.5% (IOTF, CDC, Polish 2010, respectively) among boys and 15.5%, 11.6% and 9.9% among girls. The prevalences of obesity were 3.3%, 6.1% and 5.5% (IOTF, CDC, Polish 2010, respectively) among boys and 3.4%, 6.3% and 5.7% among girls. The different methods used generally showed good agreement. Nevertheless the prevalence of overweight and obesity differed significantly depending on the criteria used. In conclusion, the creation and updating of national databases based on large, representative groups is justified and provides the best reference for regional data. However, in order to ensure the comparability of results with those from other countries, it seems advisable to use cut-offs based on international data as well.

Abstract
BACKGROUND To evaluate if there are departures from the WHO Child Growth Standards (WHO-CGS) in postnatal growth of healthy 'Canadian' children in Ontario up to age 2 years, including by infant feeding and ethnicity. METHODS We included data on 9964 healthy, singleton children born in Ontario, Canada. Smoothed weight, length and body mass index (BMI) percentile curves were generated using quantile regression for the Canadian cohort from birth to age 2 years. Differences in percentile values were calculated comparing Canadian children vs. the WHO-CGS. RESULTS Canadian children under age 2 years were longer than the WHO-CGS at the 10th (0.8 cm), 50th (1.3 cm) and 90th (1.9 cm) percentiles. Canadian children incrementally surpassed the WHO-CGS in weight after age 6 months, and in BMI after 9 months. By age 2 years, the 50th percentile weight of Canadian males was 823 g (95% confidence interval (CI) 680, 965) higher than the WHO-CGS 50th percentile. Weight differences were seen regardless of feeding practice, and were greatest among children of mothers born in Canada and Europe/Western nations, and least for those of East Asian/Pacific or South Asian heritage. Among Canadian breastfed males, 18% (95% CI 16, 19) of newborns and 26% (95% CI 20, 33) toddlers aged 2 years were classified by WHO-CGS as weighing >90th percentile - much higher than the expected rate of 10%. Similarities were seen for differences in BMI. CONCLUSIONS Healthy Canadian infants/toddlers are longer and heavier than the WHO-CGS norms. Explanations for these discrepancies require further elucidation.

Abstract
BACKGROUND The study concerns the comparison of percentile curves of Czech breastfed children with Czech national references from 1991 and 2001 and WHO growth standards. Growth charts of breastfed children demonstrate different curve shapes, especially in the first months of life. Incorrect interpretation of the growth curve could lead to premature introduction of complementary foods or infant formula. AIM The comparison of four body parameters of Czech breastfed children with currently used Czech national references and WHO standards in order to recommend that Czech paediatricians use either Czech references or WHO standards in their practice. SUBJECTS AND METHODS Nine hundred and sixty breastfed children were included in the study of length-for-age, head circumference-for-age, weight-for-age and weight-for-length parameters. All percentile curves were compared. Values of the 50th percentile expressed in z-scores based on both Czech references and WHO standards were tested. RESULTS The study confirmed results of previous surveys documenting that growth of breastfed children is specific. Nevertheless, percentile curves of growth parameters of Czech breastfed children are closer to Czech references than WHO standards. CONCLUSIONS The Czech national references fulfil the needs of Czech paediatricians (with pointing to specifics of breastfed child growth) and WHO standards are suitable, especially for international comparison.

Abstract
The early diagnosis of short stature is essential for effective management and treatment. Investigations for children with growth failure are required to distinguish between idiopathic short stature due to physiological variants (familial short stature, and constitutional delays of growth and puberty, or both), primary causes of short stature, such as syndromic and/or genetic defects and skeletal dysplasia, and secondary growth deficits due to endocrine or other chronic disorders such as celiac disease, Crohn's disease, malnutrition, renal, anorexia nervosa or other chronic diseases.

Abstract
BACKGROUND Assessment of growth using Z-score methods is important for clinical care and research, yet growth reference Z-score data for preschool Saudi children are not available. OBJECTIVE Establish Z-score tables and corresponding growth charts. DESIGN Uses data from a national survey in 2004-2005. SETTING Community-based random sample of preschool Saudi children. SUBJECTS AND METHODS Raw data from the previous nationally representative sample were analyzed using the L, M, and S statistical methods to calculate Z-scores of growth. MAIN OUTCOME MEASURE(S) Z-scores reference values for weight, length/height, head circumference, weight for length/height, and body mass index for age for boys and girls from birth to 60 months of age. RESULTS For 15 601 Saudi children (7896, 50.6 % boys) Z-score tables and graphs from birth to 60 months of age were derived for boys and girls. The tables and graphs include weight for age, length/height for age, head circumference for age, weight for length/height, and BMI for age. CONCLUSION Z-score reference data on the growth of preschool Saudi infants and children is essential for healthcare and research. LIMITATION Does not include regional variations.

Abstract
The use of appropriate growth standards/references is of significant clinical importance in assessing the height of children with short stature as it may determine eligibility for appropriate therapy. The aim of this study was to determine the impact of using World Health Organization (WHO) instead of national growth standards/references on height assessment in short children. Data were collected from routine clinical practice (1998–2014) from nine European countries that have available national growth references and were enrolled in NordiNet® International Outcome Study (IOS) (NCT00960128), a large-scale, non-interventional, multinational study. The patient cohort consisted of 5996 short pediatric patients diagnosed with growth hormone deficiency (GHD), Turner syndrome (TS) or born small for gestational age (SGA). The proportions of children with baseline height standard deviation score (SDS) below clinical cut-off values (–2 SDS for GHD and TS; –2.5 SDS for SGA) based on national growth references and WHO growth standards/references were compared for children aged <5 years and children aged ≥5 years. In seven of the countries evaluated, significantly fewer children aged ≥5 years with GHD (22%; P<0.0001), TS (21%; P<0.0001) or born SGA (32%; P<0.0001) had height below clinical cut-off values using WHO growth references vs. national references. Likewise, among children aged <5 years in the pooled analysis of the same seven countries, a significantly lower proportion of children with GHD (8%; P<0.0001), TS (12%; P = 0.0003) or born SGA (12%; P<0.0001) had height below clinical cut-off values using WHO growth standards vs. national references. In conclusion, in NordiNet® IOS the number of patients misclassified using WHO growth standards/references was significantly higher than with national references. This study highlights that, although no growth reference has 100% sensitivity for identifying growth disorders, the most recent national or regional growth charts may offer the most appropriate tool for monitoring childhood growth in Europe.

Lancet Diabetes Endocrinol 2016; 4:447-56.

Abstract
Growth monitoring of apparently healthy children aims at early detection of serious underlying disorders. However, existing growth-monitoring practices are mainly based on suboptimal methods, which can result in delayed diagnosis of severe diseases and inappropriate referrals. We did a systematic review to address two key and interconnected questions underlying growth monitoring: which conditions should be targeted, and how should abnormal growth be defined? We systematically searched for studies reporting algorithms for growth monitoring in children and studies comparing the performance of new WHO growth charts with that of other growth charts. Among 1556 identified citations, 69 met the inclusion criteria. Six target conditions have mainly been studied: Turner syndrome, coeliac disease, cystic fibrosis, growth hormone deficiency, renal tubular acidosis, and small for gestational age with no catch-up after 2 or 3 years. Seven algorithms to define abnormal growth have been proposed in the past 20 years, but their level of validation is low, and their overall sensitivities and specificities vary substantially; however, the Grote and Saari clinical decision rules seem the most promising. Two studies reported that WHO growth charts had poorer performance compared with other existing growth charts for early detection of target conditions. Available data suggest a large gap between the widespread implementation of growth monitoring and its level of evidence or the clinical implications of early detection of serious disorders in children. Further investigations are needed to standardise the practice of growth monitoring, with a consensus on a few priority target conditions and with internationally validated clinical decision rules to define abnormal growth, including the selection of appropriate growth charts.

Abstract
Background Monitoring a child’s growth status helps to diagnose diseases and implement curative and preventive measures. The aim of this study was to assess how well preschool children of Russian city (Nizhny Novgorod) match with, or diverge from, international growth charts (WHO2006,2007; USCDC2000). Methods Cross-sectional study included 3,130 children aged 3–7 years attending municipal preschools of Nizhny Novgorod, the city in the European part of Russia. The study was held from February 2012 to October 2013. The international WHO2006,2007 and USCDC2000 growth references were used to calculate the height, weight and BMI z-scores. The distributions of z-scores were analysed with descriptive and inferential statistical methods. Z-score equal 0.25 was considered as a benchmark for clinically significant differences. Results Means height z-scores calculated with the use of WHO2006, 2007 and USCDC2000 references were above the 50th centile (0.13 – 0.47) for both boys and girls. The means height z-scores was less than 0.25 SD above the 50th centile only for WHO2006. Stunting prevalence (the height-for-age z-score less than -2) was slightly higher under WHO2006 (3-4 %) than under USCDC 2000 (2–3 %). Stunting prevalence among children aged 5–7 years was similar under WHO2007 and USCDC2000 references (1 %). For boys and girls aged 3–4 years the thinness prevalence, using WHO2006 was 2 %, using USCDC2000 was 6 % (p < 0.05). At the age 5–7 years this proportion under WHO2007 was 3 % in both sex groups, under USCDC2000 was 8 % for boys and 6 % for girls (p < 0.05). A proportion of preschoolers aged 3–4 years with overweight was slightly higher under WHO2006 reference (13–15 %) than under USCDC2000 (12–14 %). In the case of age 5–7 years the overweight prevalence under WHO2007 (13–12 %) was lower than under USCDC2000 (14 %). Obesity prevalence under WHO2006,2007 (3–4 %) was slightly higher than that under USCDC2000 reference (2–3 %). Preschoolers’ distribution by groups of normal weight, overweight, obesity didn’t significantly differ among the references (chi-square). Conclusions The growth assessment of children aged 3–7 years attending municipal preschools of the Russian city Nizhny Novgorod under the international references (WHO2006,2007; USCDC 2000), demonstrated that the height fit to the WHO2006 standard for the children aged 3 and 4 was generally fine, since all the mean values were within 0.25 of the standard deviations of the mean. Beyond the age of 5 the fit to the WHO2007 was poor while the fit to the USCDC2000 was poor throughout.

Abstract
BACKGROUND Idiopathic short stature (ISS) has a strong familial component, but genetics explains only part of it. Indeed, environmental factors act on human growth either directly or through epigenetic factors that remain to be determined. Given the importance of the GH/IGF1 axis for child growth, we suspected that such epigenetic factors could involve the CG methylation at the IGF1 gene P2 promoter, which was recently shown to be a transcriptional regulator for IGF1 gene and a major contributor to GH sensitivity. OBJECTIVE Explore whether the methylation of the two IGF1 low-CG-rich promoters (P1 and P2) is associated with ISS. SUBJECTS AND METHODS A total of 94 children with ISS were compared with 119 age-matched children of normal height for the methylation of CGs located within the IGF1 promoters measured with bisulphite PCR pyrosequencing. RESULTS The methylation of 5 CGs of the P2 promoter was higher in ISS children, notably CG-137 (49 ± 4% in ISS vs 46 ± 4 % in control children, P = 9 × 10-5 ). This was also true for CG-611 of the P1 promoter (93 ± 3% vs 91 ± 3% P = 10-4 ). The CG methylation of the IGF1 promoters thus takes place among the multifactorial factors that are associated with ISS.

Abstract
BACKGROUND Previous growth charts for Saudi children have not included detailed tables and parameters needed for research and incorporation in electronic records. OBJECTIVES The objective of this report is to publish the L, M, and S parameters and percentiles as well as the corresponding growth charts for Saudi preschool children. DESIGN Community-based survey and measurement of growth parameters in a sample selected by a multistage probability procedure. SETTING A stratified listing of the Saudi population. SUBJECTS AND METHODS Raw data from the previous nationally-representative sample were reanalyzed using the Lambda-Mu-Sigma (LMS) methodology to calculate the L, M, and S parameters of percentiles (from 3rd to 97th) for weight, length/height, head circumference, and body mass index-for-age, and weight for-length/height for boys and girls from birth to 60 months. MAIN OUTCOME MEASURES Length or height and weight of Saudi preschool children. RESULTS There were 15601 Saudi children younger than 60 months of age, 7896 (50.6 %) were boys. The LMS parameters for weight for age from birth to 60 months (5 years) are reported for the 3rd, 5th, 10th, 25th, 50th, 75th, 90th, 95th, and 97th percentiles as well as the corresponding graphs. Similarly, the LMS parameters for length/height-for-age, head circumference-for-age, weight-for-length/height and body mass index-for-age (BMi) are shown with the corresponding graphs for boys and girls. CONCLUSION Using the data in this report, clinicians and researchers can assess the growth of Saudi preschool children. LIMITATIONS The report does not reflect interregional variations in growth.

Abstract
AIM To evaluate the prevalence of overweight and obesity in paediatric type 1 diabetes (T1D) subjects, based on four commonly used reference populations. METHODS Using WHO, IOTF, AGA (German pediatric obesity), and KiGGS (German Health Interview and Examination Survey for Children and Adolescents) reference populations, prevalence of overweight (≥90th percentile) and obesity (≥97th percentile) and time trend between 2000 (n = 9,461) and 2013 (n = 18,382) were determined in 2-18-year-old T1D patients documented in the German/Austrian DPV database. RESULTS In 2000, the overweight prevalence was the highest according to IOTF (22.3%), followed by WHO (20.8%), AGA (15.5%), and KiGGS (9.4%). The respective rates in 2013 were IOTF (24.8%), WHO (22.9%), AGA (18.2%), and KiGGS (11.7%). Obesity prevalence in 2000 was the highest according to WHO (7.9%), followed by AGA (4.5%), IOTF (3.1%), and KiGGS (1.8%). In 2013, the respective rates were WHO (9.6%), AGA (6.2%), IOTF (4.5%), and KiGGS (2.6%). Overall, the prevalence of overweight and obesity increased from 2000 to 2006 (p < 0.001) but showed stabilization thereafter in girls and overweight in boys. CONCLUSION Overweight and obesity prevalence in T1D subjects differs significantly if it is assessed by four separate reference populations. More detailed assessment of each child is required to determine obesity-related risks.
