“…Information regarding birth weight is of great importance as it is an indirect indicator of maternal nutrition and predictive indicator of potential neonatal death and malnutrition if the child survives [3]. LBW babies have higher probability of dying within the first month of life or associated with adverse health outcomes like stunted growth [4], delayed motor and social development or learning disabilities [5], lower IQ [6], and high mortality [7]. Also LBW shares higher proportion of global neonatal mortality which is estimated to be around 60-80% [8].…”

Background. Low birth weight (LBW) is defined as the birth weight of live born infants below 2500 g, regardless of gestational age. It is a public health problem caused by factors that are potentially modifiable. The purpose of this study was to determine the socioeconomic, obstetric, and maternal factors associated with LBW in Lumbini Provincial Hospital, Nepal. Methods. The study was conducted using case control study design with 1 : 2 case control ratio. A total of 105 cases and 210 controls were taken in this study. Data were entered on Epi data software version 3.1 and exported to Statistical Package for Social Science (SPSS) software version 25 for analysis. Characteristics of the sample were described using mean and standard deviation. Bivariate analysis was done to assess the association between dependent and independent variables. The ultimate measure of association was odds ratio. Variables found to be associated with bivariate analysis were entered into a multivariable logistic regression model to identify predictors of LBW. Results. The mean age of the participants was 25.98 years with ±4.40 standard deviation. Mothers with literate educational background (AOR 0.32, 95% CI 0.13–0.81), housewife (AOR 2.63, 95% CI 1.11–6.20), vaginal mode of delivery (AOR 0.45, 95% CI 0.25–0.82), gestational age <37 weeks (AOR 2.51, 95% CI 1.15–5.48), history of LBW (AOR 5.12, 95% CI 1.93–13.60), and maternal weight <50 kilograms (AOR 2.23, 95% CI 1.23–4.02) were significantly associated with LBW. Conclusion. Educational and occupational status, mode of delivery, gestational age, maternal weight, and history of LBW were found to be independent predictors of LBW. There is need of developing coordination with education sector for increasing educational status of mothers and adolescent girls. Social determinants of health need to be considered while developing interventional programs. Similarly, interventional programs need to be developed considering identified predictors of low birth weight.

“…Birth weight and head circumference at birth are indicators of intrauterine growth and brain development, respectively . Larger birth weight, the most widely researched birth size measure, is associated with better cognitive function and higher intelligence from infancy through the third decade of life in several populations and countries independent of social background . This association of birth weight with cognition occurs across the whole spectrum of birth weight rather than being confined to an extreme group.…”

Introduction Recent evidence suggests that growth restriction in utero may lead to neurocognitive disorders in late life, either through impaired brain development or adverse metabolic programming. Methods Systematic review of literature investigating the relationship between size at birth and cognitive abilities in late life. The search, data extraction, and rating for the quality of reporting were conducted independently by two researchers. Results Of 533 selected studies, 11 were included in this systematic review and 10 of these were from high‐income setting. Of these 11 studies, eight indicated that lower birth weight is a risk factor for lower cognitive function in late life, at least in high‐income countries. The reported effect sizes were small and it was not possible to conduct meta‐analyses because of clinical heterogeneity Discussion A modest association of lower birth weight with lower cognitive abilities in late life is consistent with persisting effects of the prenatal environment on brain function. As with all observational studies, confounding is an alternative explanation. Further studies are required to elucidate the mechanisms.

Introducción: El nacimiento prematuro lleva implícito una situación de inmadurez que afecta a todos los sistemas anatómicos y funcionales del recién nacido, condición de especial vulnerabilidad, con una frecuente asociación con otras patologías y/o alteraciones del desarrollo infantil.Objetivo: Conocer las dificultades en la escuela que pueden presentar los niños y niñas nacidos muy prematuros.Material y Métodos: Revisión bibliográfica en bases de datos como Pubmed, Medline, Scielo, Cochrane; seleccionando artículos científicos tanto en español como en inglés de los últimos 10 años. Resultados: Los niños y las niñas que nacen muy prematuros y/o con bajo peso al nacer, tienen un mayor riesgo de presentar dificultades que pueden perjudicar su correcto desarrollo en la infancia y la adolescencia. Algunas de las necesidades evidenciadas a nivel motor son el retraso motor simple y la parálisis cerebral; a nivel sensorio-cognitivo, fueron los problemas de aprendizaje y alteraciones sensoriales mayores; y a nivel socioemocional, se evidencian trastornos comportamentales como es la hiperactividad y trastornos emocionales como son la depresión, quejas somáticas, temores y fobias. Conclusiones: Los profesionales de salud, de la educación y las familias, deben conocer el riesgo que presentan los grandes prematuros de presentar dificultades y/o alteraciones que pueden interferir en la vida escolar, con el fin de trabajar conjuntamente en la prevención de dichas dificultades con una intervención temprana. El cuidado de enfermería debe ir mucho más allá de la situación aguda del recién nacido, siendo agente promotor de salud en todas las etapas de la vida del niño/a. Introduction: Premature birth implicitly involves a situation of immaturity that affects all the anatomicaland functional systems of the newborn, a condition of special vulnerability, with a frequent association with other pathologies and / or alterations in child development.Objetive: To know the difficulties in school that children born very premature can presentMaterial and Methods: Bibliographic review in databases such as Pubmed, Medline, Scielo, Cochrane; selecting scientific articles in both Spanish and English for the last 10 years.Results: Children born very premature and / or with low birth weight, have a higher risk of presenting difficulties that may impair their proper development in childhood and adolescence. Some of the needs evidenced at the motor level are simple motor delay and cerebral palsy; at sensory-cognitive level, there were learning problems and major sensory alterations; and at a social-emotional level, there are behavioral disorders such as hyperactivity and emotional disorders such as depression, somatic complaints, fears and phobias.Conclusions: Health professionals, education and families must know the risk presented by large premature children to present difficulties and / or alterations that may interfere with school life, in order to work together in the prevention of such difficulties with a early intervention. Nursing care must go far beyond the acute situation of the newborn, being a promoter of health in all stages of the child's life.
