Age at menarche is regarded as a sensitive indicator of physical, biological, and psychosocial environment. The aim of this study was to determine the age at menarche and its association with biological and socioeconomic factors in girls from Santa Rosa (La Pampa, Argentina). An observational cross-sectional study was carried out on 1,221 schoolgirls aged 9-15 years. Menarche data were obtained by the status-quo method. Height, sitting height, weight, arm circumference, tricipital and subscapular skinfolds were measured. We also calculated body mass index, measures of body composition and proportions, and fat distribution. To assess socioeconomic factors, parents completed a self-administered questionnaire about their occupation and education, family size, household, and other family characteristics. The median age at menarche - estimated by the logit method--was 12.84 years (95% CI: 12.71, 12.97). Compared with their premenarcheal age peers, postmenarcheal girls had greater anthropometric dimensions through age 12. After this age, only height was higher in the latter group. Data were processed by fitting two logistic regressions, both including age. The first model included anthropometric variables and birth weight, while the second model included the socioeconomic variables. The significant variables derived from each model were incorporated into a new regression: height, sitting height ratio (first model), and maternal education (second model). These three variables remained significantly associated with menarche. The results suggest a relationship between linear growth and menarche and agree with those found in other populations where the advancement of menarche is associated with improved living conditions. In relatively uniform urban contexts, maternal education may be a good proxy for the standard of living.

Riesgo neurológico en el niño de mediano riesgo neonatalResumen INTRODUCCIÓN: los neonatos de mediano riesgo suelen presentar alteraciones del neurodesarrollo, sutiles o inaparentes, que pueden evidenciarse a mediano y a largo plazos; es por ello que se les considera niños de riesgo neurológico. La identificación de los factores de riesgo asociados con los problemas del neurodesarrollo es un primer paso para prevenir o reducir sus efectos.OBJETIVO: con esta revisión cualitativa de la literatura especializada pretendemos describir las características de un grupo de neonatos denominados colectivamente recién nacidos de mediano riesgo neonatal y que, al nacer, no presentan compromiso evidente del desarrollo neurológico. Indagamos, también sobre los factores etiológicos asociados con esta condición. MATERIALES Y MÉTODOS:realizamos una búsqueda bibliográfica en las bases Scientific Electronic Library Online (SciELO), Literatura Latinoamericana y del Caribe en Ciencias de la Salud (LILACS), la Biblioteca Nacional de Medicina de Estados Unidos de Norte América (NLM-Medline) y la Red de Revistas Científicas de América Latina y el Caribe, España y Portugal (RedALyC) centrada en factores de riesgo neurológico.RESULTADOS: el incremento de los controles prenatales, la reducción de los nacimientos pretérmino y del parto por cesárea son factores relevantes para el óptimo neurodesarrollo. Luego del parto es necesario extremar los cuidados del neonato en las Unidades de Cuidado Intensivo Neonatal controlando cuadros tales como la hiperbilirrubinemia, la sepsis neonatal y la dificultad respiratoria, asociados con alteraciones del desarrollo en los neonatos de mediano riesgo.CONCLUSIONES: las intervenciones para evitar o reducir el riesgo neurológico en los neonatos de mediano riesgo deben establecerse desde el inicio de la gestación y continuar durante toda la permanencia en las Unidades de Cuidado Intensivo Neonatal.PALABRAS CLAVE: recién nacido, trastornos del neurodesarrollo, factores de riesgo, neonatología, desarrollo infantil. OBJECTIVE:To describe the characteristics of a group of newborns collectively referred to as moderate-risk neonates, who at birth do not show neurodevelopmental disorders, and to investigate the etiological factors associated with this condition. METHODS:We carried a bibliographic search was performed in the SciELO, LILACS, Medline and RedALyC databases focused on neurological risk factors. RESULTS:Increased prenatal control and the reduction of preterm and cesarean delivery are important factors for optimal neurodevelopment. After delivery, newborn care in NICUs is critical, by controlling pathologies such as hyperbilirubinemia, neonatal sepsis, and respiratory distress associated with developmental abnormalities in MRN. CONCLUSIONS:Interventions to avoid or reduce neurological risk in MRN must be established from the beginning of pregnancy and continued during the NICU stay.
Introduction: Infancy is the period of greatest neuroplasticity. The early detection of developmental disorders helps to provide a timely intervention aimed at reducing sequelae and/or complications. Objective: To assess psychomotor and cognitive development in infants between 6 and 9 months old assisted in the public health sector. Population and methods: Descriptive study with follow-up of full-term infants who were clinically healthy at the time of assessment and had an adequate weight, height, and head circumference for their age. The Assessment Scale of Psychomotor Development and the Argentine Scale of Sensorimotor Intelligence were used in infants aged 6-9 months. Early stimulation was the intervention provided to those who showed a risk or delay. The prevalence of risk/delay of psychomotor development and sensorimotor intelligence was determined. The statistical software package R, version 3.3.1 was used. Results: A total of 102 children were assessed. At 6 months old, 22.5 % had a developmental risk/delay. The prevalence of unexpected results for age in psychomotor development and sensorimotor intelligence was 13.7 % and 16.7 %, respectively. These children received early stimulation and all showed improved results. At 9 months old, the prevalence of risk/delay was 20.6 %: 14.7 % in psychomotor development and 9.8 % in sensorimotor intelligence. Conclusion: At 6 months old, 22.5 % of infants had a developmental risk/delay; at 9 months old, this prevalence was 20.6 %. An early assessment of development helped to detect disorders and provide an early intervention.
