“…Furthermore, a study performed in Brazil demonstrated that growth status represents a factor associated with attention deficit-hyperactivity disorder 21 . Moreover, a recent study showed that children stunted in early childhood had more conduct problems at home, regardless of their social backgrounds, and fewer prosocial behaviors at school than non-stunted children 22 .…”

Growth retardation -as measured by low heightfor-age -during infancy and early childhood has been found to have a strong adverse effect on cognitive function in late childhood [1][2][3] . However, less is known about relationships between growth impairment and behavior and neuropsychological performance. In Brazil, to a large extent, research in child neuropsychology has been hindered by the lack of normative data for neurobehavioral assessment in children 4 . Earlier research of the first author has focused on the development of normative data for neuropsychological instruments used in the assessment of children in Brazil such as the Conners Abbreviated Teacher Rating Scale 5 , the Teacher Rating Scale-Brazil (TRS-B) 6 , the Edinburgh Handedness Inventory 7-8 , the Attention Deficit/Hyperactivity Disorder Teacher Rating Scale-Brazil (ADHD-DSM-IIIR-B) 9 , the Steadiness Test and the Purdue Pegboard 10 . The ABSTRACT -Aim: To assess the association between child growth and teacher-reported behavior and academic standing, and neuropsychological performance. Method: The heights of 344 public-school children were measured using standard procedures. Teachers were requested to complete two behavioral and one academic performance rating scales. Neuropsychological assessment consisted of the Edinburgh Handedness Inventory, the Steadiness Test and the Purdue Pegboard. Height-for-age z (HAZ) scores were calculated based on an international reference. Standard (z) scores for each factor of the first two behavioral rating scales and for each neuropsychological variable were computed for each child based on locally-derived norms. Results: HAZ scores were negatively correlated with factors related to hyperactivity, conduct problem, impulsivity and inattention of the behavioral rating scales. In addition, the lower the HAZ score the worse the academic performance. Conclusion: These results add to the existing evidence indicating a strong association between growth status and child behavior and academic performance.

Método: A estatura de 344 escolares da rede pú-blica de Niterói foi medida através de procedimentos padronizados. Os professores preencheram duas escalas de avaliação comportamental e uma escala de avaliação do rendimento acadêmico. O exame neuropsicológico incluiu o Inventário da Preferência Manual de Edimburgo, o Teste do Equilíbrio da Haste e a Prancha de Purdue. Escores padronizados da estatura para a idade (HAZ) foram calculados com base em referên-cia internacional. Escores padronizados (z) dos fatores das duas escalas de avaliação comportamental e das variáveis neuropsicológicas foram computados para cada criança com base em norm...

Objective: to investigate the neurological performance of elementary school students from the city of Porto Alegre, state of Rio Grande do Sul, Brazil, in order to assess the association of neurological development and nutritional status. Methods: we carried out an observational, analytical, and crosssectional study on a random and proportional population sample selected out of all first-grade students (n=35,521) in the city of Porto Alegre for a total of 484 children, out of which 64.7% were enrolled in state public schools, 11.9% in city public schools, and 23.4% in private schools. Our sample size allowed for a precision of ± 3% (95% confidence interval) for an estimated prevalence of 10% of cortical dysfunction. Children were submitted to individual examinations at the school. We collected data regarding sex, age, color of skin, nutritional status, and school of origin. An informed consent was obtained from the State and City Departments of Education and from the principals of the private schools. Statistical analysis was carried out using the chi-square test and ANOVA. Results: from 11.4% to 38.2% of children presented ENE results lower than expected according to their age. The most affected factors were sensory activity and gnosia (38.2%), and the least affected factor was motor persistence (11.4%). There were no statistically significant differences between boys and girls. We observed an association of children with low height-forage and weight-forage and cortical dysfunction. Conclusions: chronic malnutrition is a risk factor for brain function performance.

Objective: to determine ASO titer profile by establishing ARF differential diagnoses of other diseases with high levels of ASO antibodies. Methods: we investigated 78 patients with ARF at onset and follow-up, 22 with isolated chorea at onset, 45 with recurrent oropharyngeal tonsillitis, and 23 with recent flare of juvenile idiopathic arthritis. We tested ASO with automated particle-enhanced immunonephelometric assay (Behring ®-Germany). The ASO (IU/ml) titers were assessed at the following time intervals: 0-7 days, 1-2 weeks, 2-4 weeks, 1-2 months, 2-4 months, 4-6 months, 6-12 months, 1-2 years, 2-3 years, 3-4 years, and 4-5 years after onset of ARF. Results: ASO titers in patients diagnosed with ARF had a significant increase up to the 2-4-month time interval (P<0.0001). Baseline levels were observed afterwards in patients under regular penicillin prophylaxis. The levels of ASO in ARF were also significantly higher than in patients with isolated chorea, recurrent oropharyngeal infections or juvenile idiopathic arthritis (P=0.0025), when age-matched samples of these groups were compared. The test's sensitivity was 73.3% and the specificity was 57.6%, and it was calculated taking into account the upper limit of normality at 320 IU/ml, as well as the established diagnosis of ARF. The test's specificity and positive predictive value increased with rising or higher titers, being higher with titers above 960 UI/ml. Conclusion: this reappraisal of ASO profile in ARF patients indicates a remarkable response during the acute phase, and that points to the extent to which ASO levels may differentiate ARF from other diseases with high levels of ASO antibodies, as coincidental but unrelated streptococcal infection or chronic arthritis flareup.
