Aim: This paper aimed to analyse the association between small for size at birth, stunting, recovery from stunting and pubertal development in a rural Bangladeshi cohort.Methods: The participants were 994 girls and 987 boys whose mothers participated in the Maternal and Infant Nutrition Interventions in Matlab trial. The birth cohort was followed from birth to puberty 2001-2017. Pubertal development according to Tanner was self-assessed. Age at menarche was determined and in boys, consecutive height measurements were used to ascertain whether pubertal growth spurt had started. The exposures and outcomes were modelled by Cox's proportional hazards analyses and logistic regression.Results: There was no difference in age at menarche between girls that were small or appropriate for gestational age at birth. Boys born small for gestational age entered their pubertal growth spurt later than those with appropriate weight. Children who were stunted had later pubertal development, age at menarche and onset of growth spurt than non-stunted children. Children who recovered from infant or early childhood stunting had similar pubertal development as non-stunted children.Conclusion: Infant and childhood stunting was associated with a later pubertal development. Recovery from stunting was not associated with earlier puberty in comparison with non-stunted children. [ABSTRACT FROM AUTHOR]

Aim: Although well documented in randomised trials, the efficacy of prophylaxis against respiratory syncytial virus (RSV) in real-word conditions is less studied. The objective was to assess the impact of partial versus full RSV prophylaxis for acute respiratory infections (ARIs) and ARI-related hospital admissions in preterm children.Methods: This study included children born preterm in 2011 in France who were eligible for RSV prophylaxis and received at least one palivizumab dose from October 2011 to March 2012. Full prophylaxis was defined as receiving at least one palivizumab dose for each month of RSV exposure in the community. Children with full and partial prophylaxis were matched, and odds of ARIs and ARI-related hospital admission were compared by logistic regression.Results: Full prophylaxis concerned 861/1083 (80%) children. As compared with full prophylaxis, partial prophylaxis was not associated with ARI occurrence (odds ratio OR 1.3, 95% confidence interval CI 0.9-1.9) but was significantly associated with ARI-related hospital admission during the RSV epidemic (OR 1.9, 95% CI 1.2-2.9).Conclusion: During the 2011-2012 RSV epidemic, hospital admission rates were higher for preterm children with partial than full RSV prophylaxis. Improving compliance could help alleviate the burden of RSV on healthcare systems. [ABSTRACT FROM AUTHOR]

Aim: This study determined possible discrepancies between verbal IQ and performance IQ in 8-year-old very preterm (VPT) and extremely preterm (EPT) children, and examined associations between verbal IQ and performance IQ, and sociodemographic factors, perinatal factors, early cognitive outcomes and also with school achievement scores.Methods: This prospective cohort study included 120 eight-year-old VPT/EPT children. Cognitive development was assessed at the ages of 2, 5 and 8 years. Eight years' school achievement results in arithmetic, reading and spelling were collected. Multiple regression analyses were performed to determine predictors of verbal IQ and performance IQ at the age of 8 years and to determine associations with school achievement scores.Results: Mean performance IQ (89.8) was significantly lower than mean verbal IQ (99.4; Cohen's d = 0.59) at the age of 8 years. Gestational age (GA), small for GA status, and cognitive scores at the ages of 2 and 5 years significantly predicted verbal IQ and performance IQ at the age of 8 years. Performance IQ at age 8 years was an important predictor for arithmetic scores (β = 0.42).Conclusion: Performance IQ was more strongly affected than verbal IQ in 8-year-old VPT/EPT children and was strongly related to mathematical difficulties.

Aim: Breastfeeding is associated with IQ, school attendance and income. Despite the known benefits of breastfeeding, the rate of exclusive breastfeeding up to 6 months is low globally. We examined the effect of short-term breastfeeding on long-term IQ.Methods: In this secondary analysis of the prospective Cork BASELINE Birth Cohort Study, children were categorised as predominantly breastfed (n = 288) versus exclusively formula-fed (n = 254) at 2-months of age. Infants (n = 404) receiving mixed feeding were excluded. Outcome was assessed using the KBIT-II at 5 years. Multivariable linear regression was used to adjust for confounding variables.Results: Following adjustment for confounding variables, children, predominately breastfed at 2 months of age, demonstrated increased overall IQ (2.00 points (95% CI: 0.35 to 3.65); P = .018) and non-verbal IQ at 5 years of age (1.88 points (95% CI: 0.22 to 3.54); P = .027) compared with those never breastfed. No significant relationship was found with verbal IQ (P = .154).Conclusion: A significant increase in composite and non-verbal IQ at 5 years of age was associated with short-term breastfeeding. This study adds to a growing body of evidence that short-term breastfeeding promotes healthy cognitive development. [ABSTRACT FROM AUTHOR]

Aim: To assess educational outcomes of twins and quantify the degree this is mediated by gestational age and other perinatal factors.Methods: We conducted a population-based record-linkage cohort study of all live births ≥24 weeks gestation in New South Wales, Australia with a corresponding standardised school test result for grade 3 in 2008-2014. The primary outcome was whether a child met the National Minimum Standard (NMS) cut-off in literacy and numeracy domains. Robust multivariable Poisson models were used to obtain adjusted relative risks (aRRs), and mediation analysis conducted to assess contributing factors on the causal pathway.Results: Of 351 791 liveborn infants, 10 365 (2.9%) were twins. After adjusting for maternal covariates and compared with singletons, twins had an increased risk of not meeting the NMS for all five literacy and numeracy domains (aRR 1.27-1.45, P < .001). Gestational age alone mediated up to 73% of aRRs and small for gestational age further attenuated these effects with only minimal risk remaining after adjusting for all mediators (aRR 0.94-1.07).Conclusion: Almost all of the educational disadvantage experienced by twins, compared with singletons, is attributable to the risk associated with shorter gestational age, and partly by poor foetal growth. These findings support efforts to prolong gestation of twin pregnancies. [ABSTRACT FROM AUTHOR]

Aim: We collected evidence and safety data for topical tacrolimus in small children with atopic dermatitis (AD) and compared the usage with topical corticosteroid.Methods: This was an interim analysis of 75 patients (55% female) at 1 year of an ongoing 3-year randomised open-label comparative follow-up study of topical tacrolimus vs corticosteroid treatment. One- to three-year-old children with moderate-to-severe eczema referred to the Skin and Allergy Hospital in Helsinki, Finland, were enrolled.Results: Efficacy parameters, the Eczema Area and Severity Index (EASI), Investigator's Global Assessment (IGA), transepidermal water loss (TEWL), eczema area, serum total immunoglobulin E (IgE) and the blood eosinophil count, showed improvement in both groups during the study. However, patients with signs of early sensitisation at baseline (elevated serum total IgE, elevated eosinophil count, positive prick tests or specific IgEs to aero or food allergens) had statistically significantly lower TEWL at the eczema site and a smaller eczema area at 12 months in the tacrolimus group. No severe adverse effects were seen during the treatment.Conclusion: Children with AD and signs of early sensitisation appeared to benefit more from early tacrolimus than corticosteroid treatment. Small children may need stronger but nevertheless safe ointment options when treating moderate-to-severe AD. [ABSTRACT FROM AUTHOR]

Aim: The emotional connection between mothers and infants born preterm has been associated with positive behaviour. The aim of this study was to examine the longitudinal association between emotional connection at six months of age and behavioural problems at three years.Methods: This study was carried out by the University of North Texas, USA and comprised 49 mothers and infants from a longitudinal investigation of family interaction and infant development conducted in 1994-1997. Face-to-face interaction and toy-based play were videotaped and coded at six months of age using the Welch Emotional Connection Screen (WECS), a brief screening tool for relational health. When the children were three years of age, the mothers reported on child behavioural problems.Results: The children from dyads that were rated as emotionally connected at six months of age had fewer externalising and internalising behavioural problems at the age of three. No links were found between emotional connection during toy-based play at six months and later child behavioural problems.Conclusion: We showed that when the WECS was used at six months of age it was a promising and valid relational screening tool for infants at risk of adverse behavioural outcomes at the age of three.

Aim: Studies of children's early ability to communicate have mainly focused on mother-child dyads. That is why this study analysed the long-term effects of triadic interactions involving both parents.Method: This prospective pilot study monitored child-mother-father communication in 19 families from the general population in Sweden using the standardised Lausanne Trilogue Play method in a video studio. The families and their first-born child were initially followed from three months to 48 months of age. Preschool teachers assessed the children at the age of four using the Preschool Behaviour Questionnaire and then their teachers assessed the subjects at the age of 15 using the Strengths and Difficulties Questionnaire. Early communication was analysed in relation to the children's social competence at the age of 15.Results: The child's skills in initiating turn-taking sequences and their parents' responses to this correlated with the child's social competence at the age of four, as reported in a previous study from our group, and at the age of 15, as reported here.Conclusion: The results of this study indicated that stimulating children's capacity to initiate turn-taking sequences in infancy improved their social competence at the age of 15, confirming positive results at four years of age.

Aim: Infants hospitalised for bronchiolitis undergo examinations and treatments not supported by current research evidence and we investigated practice variations with regard to Finnish children under the age of two.Methods: This prospective, multicentre cohort study was conducted in paediatric units in three university hospitals in Finland from 2008 to 2010. Hospital medical records were reviewed to collect data on clinical course, testing and treatment. Data were analysed separately for children meeting our strict definition of bronchiolitis, aged under 12 months without a history of wheezing, and a loose definition, aged 12-23 months or with a history of wheezing.Results: The median age of the 408 children was 8.1 months. Clinical management varied between the three hospitals when stratified by strict and loose bronchiolitis subgroup definitions: complete blood counts ranged from 15-95% vs 16-94%, respectively, and the other measures were chest x-ray (16-91% vs 14-72%), intravenous fluids (2-47% vs 2-41%), use of nebulised epinephrine (10-84% vs 7-50%), use of salbutamol (18-21% vs 13-84%) and use of corticosteroids (6-23% vs 60-76%).Conclusion: The clinical management of bronchiolitis varied considerably with regard to the three hospitals and the two definitions of bronchiolitis. A stronger commitment to evidence-based bronchiolitis guidelines is needed in Finland. [ABSTRACT FROM AUTHOR]

Aim: This study established predictive properties of single language milestones for specific language impairment (SLI) after the age of four, as these had not previously been reported in the literature.Methods: In this nested case-control study, children attending special needs schools for severe speech and language difficulties were matched with children attending mainstream schools. Data covering the ages of zero to four years were retrieved from well-child care clinics and the outcomes of 23 language milestones in the Dutch Developmental Instrument were analysed. The predictive properties were expressed as positive likelihood ratios, sensitivity and specificity.Results: We included 253 pairs of children with and without SLI, aged from four to 11 years. The mean age was eight years and three months, and 77% were boys. From the age of 18 months, cases and controls differed significantly on all milestones (p < 0.01). After 24 months, the language milestones had positive likelihood ratios that ranging from 6 to 108. In general, language milestones had a high specificity (range 77-100%), but the sensitivity was relatively low (range 0-68%).Conclusion: Failure to meet language milestones from the age of 24 months was predictive of SLI, but the use of separate milestones had limited value due to low sensitivity.

Aim: This study compared postnatal growth patterns calculated using different reference data in a large cohort of very preterm infants.Methods: The weight, length and head circumference of 551 very preterm infants born in the Tyrol, Austria, between 2003 and 2011, were obtained at birth, discharge and the corrected ages of three, 12 and 24 months. Growth data are presented as Z-scores in relation to four reference populations: LMS growth by Pan et al., Fenton preterm growth charts, the Euro-Growth Study Group and the World Health Organization (WHO) Anthro programme.Results: We observed significant differences in mean weight Z-scores using the four reference populations, with the WHO data being the highest. The mean head circumference Z-scores also differed significantly at all time points. We observed a pronounced gap in the microcephaly rate, which was 10 times higher at the age of 24 months if the Pan data were used instead of the WHO data.Conclusion: Our findings revealed significant deviations between the interpretation of postnatal growth depending on the reference data used, with the most striking differences seen in head circumference. The choice of reference data, and particularly the conclusions drawn from the data, must be interpreted with utmost care. [ABSTRACT FROM AUTHOR]

Aim: Published Growth studies from Latin America are limited to growth references from Argentina and Venezuela. The aim of this study was to construct reference growth curves for height, weight, body mass index (BMI) and head circumference of Colombian children in a format that is useful for following the growth of the individual child and as a tool for public health.Methods: Prospective measurements from 27 209 Colombian children from middle and upper socio-economic level families were processed using the generalised additive models for location, scale and shape (GAMLSS).Results: Descriptive statistics for length and height, weight, BMI and head circumference for age are given as raw and smoothed values. Final height was 172.3 cm for boys and 159.4 cm for girls. Weight at 18 years of age was 64.0 kg for boys and 54 kg for girls. Growth curves are presented in a ± 3 SD format using logarithmic axes.Conclusion: The constructed reference growth curves are a start for following secular trends in Colombia and are also in the presented layout an optimal clinical tool for health care.

Follow-up study found that vitamin D deficiency and weight gain increased the risk of impaired fasting glycaemia Vitamin D deficiency, as measured by 25-hydroxyvitamin D, has been related to obesity and impaired fasting glycaemia (IFG), but the causality is unclear. No data on the duration of vitamin D deficiency were available, but the IFG risk did not increase for children who developed vitamin D deficiency during the follow-up period.
