| description | Objective: To examine whether advanced maternal age (≥40 years) is linked to an increased likelihood of low or high birth weight among native and foreign-born mothers giving birth in Spain. Method: A cross-sectional study was conducted using a novel database provided by the Spanish National Statistics Office which links the 2011 Census with information on individual births (2011-2015) from the Vital Statistics (Natural Movement of the Population). First, multinomial logistic regression models were used to estimate the potential association between maternal age and the likelihood of having a baby with low or high birth weight. Second, average adjusted predictions of giving birth to children with low, high, and adequate weight for the origin and the maternal age at birth were also calculated. Results: Findings indicate that women with advanced maternal age showed an increased probability of giving birth to low birth weight infants. Conversely, mothers aged below < 30 years had an elevated risk for high birth weight infants. When considering maternal migratory status, the findings were mixed. On one hand, foreign-born mothers showed a higher likelihood of delivering infants with high birth weight; on the other, they displayed a lower risk of low birth weight among newborns in comparison to Spanish natives. Conclusions: The study addresses two key aspects. First, it highlights the increased risk of low birth weight in mothers delivering at an advanced age. Second, it emphasizes the importance of accounting for maternal migratory status when investigating the association between age at birth and birth weight outcomes among immigrant mothers. Resumen: Objetivo: Examinar si la edad materna avanzada (>40 años) está relacionada con una mayor probabilidad de bajo o alto peso al nacer en los nacidos de madres inmigrantes y nativas en España. Método: Se utiliza una base de datos novedosa proporcionada por el Instituto Nacional de Estadística de España que vincula el Censo de 2011 con información sobre nacimientos individuales (2011-2015) de las Estadísticas Vitales (Movimiento Natural de la Población). Los modelos de regresión logística multinomial se utilizaron para estimar la posible asociación entre la edad materna y la probabilidad de bajo o alto peso en los nacidos. Se calcularon predicciones ajustadas promedio para el peso bajo, alto y adecuado según el origen y la edad materna. Resultados: La edad materna avanzada se asocia con una mayor probabilidad de bajo peso en los nacidos. Por el contrario, las madres menores de 30 años presentan un riesgo elevado de tener bebés con alto peso. Sin embargo, al considerar el origen materno, los resultados fueron mixtos. Por un lado, las madres nacidas en el extranjero mostraron una mayor probabilidad de nacidos con alto peso; por otro, presentaron un menor riesgo de bajo peso en los nacidos. Conclusiones: El estudio destaca dos aspectos clave. En primer lugar, pone de relieve el mayor riesgo de bajo peso al nacer en las madres que dan a luz a una edad avanzada. En segundo, la importancia de tener en cuenta el estatus migratorio materno en la asociación entre la edad materna y el peso al nacer. |
