RESUMEN

OBJETIVO:

Determinar los recién nacidos pequeños para la edad gestacional (RN PEG), al emplearlas curvas de crecimiento intrauterino (CCIU) peruanas, y estudiar sus riesgos de morbimortalidad.

DISEÑO:

Estudio prospectivo, analítico, de casos y controles. LUGAR Hospitales del Ministerio de Salud del Perú (MSP). PARTICIPANTES Recién nacidos. INTERVENCIONES Fueron clasificados 95 751 neonatos de 29 hospitales del MSP, nacidos en el año 2005 aplicando CCIU por peso, de Lubchenco y del Perú. Se comparó la distribución porcentual, considerando diferencias significativas cuando p menor que 0,05. Se estudió los riesgos de morbimortalidad de los RN PEG adicionales, denominados ‘nuevos PEG’, en comparación con los adecuados para edad gestacional (AEG), dela semana 37 a la 42, utilizando odds ratio, con intervalo de confianza al 95 por ciento. Se utilizó el Sistema Informático Perinatal. PRINCIPALES MEDIDAS DE

RESULTADOS:

Porcentajes de recién nacidos adecuados, grandes o pequeños para la edad gestacional; riesgos de los recién nacidos ‘nuevos’ PEG.

RESULTADOS:

Los RN grandes para la edad gestacional (GEG) disminuyeron significativamente de 14,3 por ciento a 11,4 por ciento, los AEG disminuyeron de 81,7 por ciento a 78,5 por ciento y los RN PEG aumentaron de 4,1 por cientoa 10,1 por ciento. Hubo 9 664 RN PEG al usar la curva peruana y 3 899 al usar la de Lubchenco. La diferencia de 5 765 RN (6 por ciento de la población total) correspondió a los ‘RN nuevos PEG’, siendo sus riesgos mortalidad neonatal (OR = 15,6), trastornos metabólicos (OR = 2,2), malformaciones congénitas (OR = 2,1), infecciones (OR = 2), síndrome de dificultad respiratoria (OR = 1,8), asfixia perinatal (OR = 1,7) y morbilidad neonatal (OR = 1,5).

CONCLUSIONES:

La curva de Lubchenco sobredimensiona los RN GEG y subdimensiona los RN PEG, siendo un patrón poco exigente para RN peruanos. El grupo de nuevos PEG presenta riesgo alto de morbimortalidad.
ABSTRACT

OBJECTIVE:

To determine small for gestational age (SGA) newborns when using the Peruvian intrauterine growth curves and to study their risk for morbidity and mortality.

DESIGN:

Prospective, analytical, case-control study.

SETTING:

Peruvian Ministry of Health hospitals.

PARTICIPANTS:

Live newborns.

INTERVENTIONS:

Ninety-five thousand seven hundred and fifty-one neonates from 29 Peruvian Ministry of Health hospitals born during 2005 were classified by applying both Lubchenco and Peruvian weight intrauterine growth curves. Percentage distribution was compared and significant differences was considered when p less than 0,05.We studied additional SGA (named new SGA) newborns risks for morbidity and mortality in comparison with adequate for gestational age (AGA) newborns, from week 37 through 42, using odds ratio with 95 per cent confidence interval. Perinatal System Informatic Data was used. MAIN OUTCOME

MEASURES:

Percentage of adequate, large and small for gestational age newborns; ‘new’ SGA’ risks.

RESULTS:

Large for gestational age (LGA) newborns diminished significantly from 14,3 per cent to 11,4 per cent, AGA decreased from 81,7 per cent to 78,5 per cent, and SGA newborns increased from 4,1 per cent to 10,1 per cent. There were 9664 SGA newborns when using the Peruvian curve and 3 899 when using Lubche nco’s. The difference of 5 765 newborns (6 per cent of the whole population) corresponds to the ‘new’ SGA newborns that presented the following risks neonatal mortality (OR = 15,6), metabolic dysfunction (OR = 2,2), congenital malformations (OR =2,1), infections (OR = 2), respiratory distress syndrome, (OR = 1,8) perinatal asphyxia (OR = 1,7) and neonatal morbidity (OR = 1,5).

CONCLUSIONS:

Lubchenco’s curve overestimates LGA newborns and underestimates SGA newborns, and as such is not a demanding standard for Peruvian newborns. The new SGA group had high morbidity and mortality risk.
