RESUMO

BACKGROUND: Relative measures of birthweight (small and large-for-gestational age, SGA-LGA) are increasingly preferred to absolute measures (low birthweight, macrosomia). In this study we assess whether the national vital statistics provided by the Spanish National Statistical Institute (INE) reliably estimate SGA and LGA. Also, we will assess whether missing data (selection) and misreported information (bias) are systematically associated with parental socioeconomic information. METHODS: We linked the information on 6,339 births at the Hospital Clínico San Carlos of Madrid (2005-06) with the vital statistics records (successful for the 95% of the observation). Validity measures and concordance were estimated for low birthweight (LBW, <2500 gr), macrosomia (>4500 gr), SGA (<10th percentile) and LGA (>90 percentile). Logistic regressions were fitted. RESULTS: The prevalence estimated with the hospital data were: LBW (6%), macrosomia (0.5%) SGA (1%) and LGA (15%) and, with the data from INE: 5% 0.5% 2% 12% respectively. Kappa statistics: LBW (83%), macrosomia (79%), PEG (24%) and LGA (82%). Missing and misreported data vary with parental nationality and their situation in the labor market (OR between 1.5 y 2.2). CONCLUSIONS: Vital statistics overestimate the prevalence of SGA and underestimate the prevalence of LGA. The concordance between the sources is very good for low birthweight, macrosomia and LGA, and moderately good for SGA. Both missing and misreported birthweight and gestational age are associated with parental socioeconomic characteristics.

RESUMO

Fundamentos: Los indicadores perinatales de peso relativo como pequeño y grande para la edad gestacional (PEG, GEG) son preferibles frente a medidas de peso absolutas (bajo peso, macrosomia). El objetivo de esta investigación fue evaluar si los datos del Instituto Nacional de Estadística (INE) tienen la fiabilidad suficiente para estimar indicadores de peso relativo y si la calidad de la información que comunican los progenitores varía según sus características sociodemográficas. Métodos: Se comparó la información de 6.339 nacimientos del Hospital Clínico San Carlos de Madrid (2005-06) con el registro de nacimientos del INE (con un éxito del 95%). Se evaluaron medidas de validación y acuerdo para los indicadores de bajo peso (BP <2500 gr), macrosomia (>4.500 gr), PEG (percentil 90). Se realizó un análisis de regresión logísticas. Resultados: Las prevalencias estimadas con los datos del hospital fueron: BP (6%), macrosomia (0,5%) PEG (1%) y GEG (15%) y con datos del INE: 5% 0,5% 2% 12%, respectivamente. La especificidad: 80%, 78%, 24%, 82%. El estadístico Kappa: BP (83%), macrosomia (79%), PEG (24%) y GEG (82%). La omisión e incorrecta declaración varió según la nacionalidad y la situación laboral de los padres (OR entre 1,5 y 2,2). Conclusiones: El INE sobreestimaría la prevalencia de PEG e infraestimaría la de GEG. El acuerdo entre las fuentes es muy bueno para BP, macrosomia y GEG y moderadamente bueno para PEG. Tanto la omisión como los errores en la declaración del peso y la edad gestacional varían en función de las características sociodemográficas de los padres (AU)

RESUMO

El movimiento natural de la población, publicado por el Instituto Nacional de Estadística (INE), constituye una fuente de enorme importancia para el estudio de la salud perinatal en el ámbito nacional. Sin embargo, se desconocen las características de la recogida de la información que afectan a la calidad y la interpretación de los estudios epidemiológicos que utilizan esta fuente. El objetivo de este estudio es dar a conocer cómo se recoge la información y algunos problemas asociados. Este trabajo es el resultado de un análisis de las notas metodológicas del INE y de la información recogida de primera mano en hospitales de Madrid, en el Registro Civil central de Madrid y en el Instituto de Estadística de Madrid (IEM). Es necesaria una mayor integración entre las instituciones involucradas para mejorar la calidad de las estadísticas de nacimientos y muertes fetales tardías (AU)


Vital statistics, published by the National Statistics Institute in Spain, are a highly important source for the study of perinatal health nationwide. However, the process of data collection is not well-known and has implications both for the quality and interpretation of the epidemiological results derived from this source. The aim of this study was to present how the information is collected and some of the associated problems. This study is the result of an analysis of the methodological notes from the National Statistics Institute and first-hand information obtained from hospitals, the Central Civil Registry of Madrid, and the Madrid Institute for Statistics. Greater integration between these institutions is required to improve the quality of birth and stillbirth statistics (AU)
