| Summary: | Objetivos: Identificar los patrones dietéticos durante el embarazo, describiendo su relación con factores sociodemográficos, tabaquismo e índice de masa corporal, y evaluar la dieta en relación con las recomendaciones dietéticas vigentes. Métodos: Valoración transversal de la dieta en 473 mujeres de Menorca (España). Los patrones dietéticos se identificaron por análisis de componentes principales. El grado de adecuación se estimó comparando el consumo promedio por grupo alimentario con lo recomendado durante el embarazo. Resultados: Se identificaron dos patrones dietéticos, uno caracterizado por alimentos de alta densidad calórica y bajo consumo de frutas y verduras, denominado «calórico», y otro caracterizado por alto consumo de verduras, legumbres, pescado, carnes, pasta y arroz, denominado «saludable». Las mujeres extranjeras, fumadoras, no nulíparas y con estudios primarios tuvieron puntuaciones más altas del patrón calórico (p<0,05). En cuanto al patrón saludable, sólo las mujeres de origen español no balear y las extranjeras presentaron puntuaciones más altas (p<0,05), mientras que el resto de las variables no se asociaron con él. La adherencia a las recomendaciones dietéticas era elevada para frutas, carnes y sobre todo lácteos, mientras que el consumo de verduras, cereales y legumbres era de un tercio de lo recomendado. Conclusiones: Los patrones dietéticos durante el embarazo fueron similares a los referidos en la población general y presentaron asociaciones consistentes con algunos factores sociodemográficos y con el tabaquismo. La falta de adecuación en verduras, legumbres y cereales refuerza la idea de evaluar la dieta durante los controles obstétricos, para promover conductas alimentarias más acordes con las recomendaciones específicas.<br>Objectives: To identify dietary patterns in pregnancy and describe their relationship with sociodemographic factors, smoking, and body mass index. As a secondary objective, intakes were evaluated relative to current dietary recommendations for pregnant women. Methods: Cross-sectional assessment of dietary intakes in 473 pregnant women from the Island of Menorca (Spain) was performed. Dietary patterns were identified using a principal components analysis, and dietary quality was assessed by comparing food group intakes with recommended intakes in pregnancy. Results: Two dietary patterns were identified, one characterized by high intakes of energy-dense foods and low intakes of fruits and vegetables («caloric»), and the other by high intakes of vegetables, legumes, fish, meat, rice and pasta («healthy»). Scores for the caloric pattern were higher in immigrants, smokers, parous women and women with only primary school education (p<0,05). Scores for the healthy pattern were higher in women originally from other parts of Spain and immigrants (p<0,05). No associations were found with the remaining variables. Adherence to dietary recommendations was high for fruit, meat and especially dairy products, while intakes of vegetables, cereals and legumes were only one-third of recommended levels. Conclusions: Dietary patterns during pregnancy were similar to previously reported patterns in the general population, showing consistent associations with sociodemographic factors and smoking. There were substantial deficiencies in intakes of cereals, legumes and vegetables in all women, suggesting the need for educational interventions and monitoring during prenatal care to improve the quality of dietary habits during pregnancy.
