ABSTRACT

Background:

Postprandial hyperlipaemia is an independent risk factor for atherosclerosis.

Objectives:

To compare postprandial lipaemia and fasting adhesion molecules levels in healthy young premenopausal(PrW) and postmenopausal (PoW) Spanish women. Subjects and

methods:

Twenty healthy PrW and 18 healthy PoW participated in a postprandial 7-hour intervention study. All participants were given a fat-rich standard meal (11.8% saturated, 39.7% monounsaturated, and 6.6% polyunsaturated) after a 12 h fast. Blood samples were taken at baseline and at 60, 120, 240, 360 and 420 min after eating. Triacylglycerols (TAG), total cholesterol (Chol), soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular adhesion molecule-1 (sVCAM-1) were determined in fasting serum samples and TAG andtotal Chol postprandial levels were measured.

Results:

Anthropometric data, serum lipid and sICAM-1 presented significant higher values in PoW compared to PrW, but sVCAM-1 did not significantly differ between groups. Postprandial TAG and Chol concentrations in PoW were significantly higher than in PrW (p < 0.0001). There was a significant time influence (p < 0.0001) in TAG in PrW and PoW, while time to peak and peak concentration were significantly higher in PoW than PrW. Chol concentrations showed a significant reduction after 1 h, to reach values similar to baseline after 6 h in PrW but not in PoW.

Conclusions:

Lipid postprandial response to a fat rich meal and soluble intercellular adhesion molecules concentrations indicate a higher cardiovascular risk pattern in postmenopausal compared to premenopausal women. Soluble vascular adhesion molecule levels seem to be influenced not only by age and menopause, but also other factors like usual diet (AU)
RESUMEN

Introducción:

La hiperlipemia postprandial es un factor independiente de riesgo de aterosclerosis.

Objetivos:

Comparar la lipemia postprandial y concentraciones en ayunas de moléculas de adhesión en mujeres sanas, jóvenes premenopáusicas (PrW) y postmenopáusicas (PoW). Sujetos y

métodos:

20 PrW y 18 PoW participaron en un estudio de intervención postprandial de 7 horas. Tras 12 horas de ayuno, las participantes tomaron una comida estándar rica en grasa (11,8% saturada, 39,7% monoinsaturada y 6,6% poliinsaturada). Se tomaron muestras de sangre basal y a los 60, 120, 240, 360 y 420 min después de comer. En las muestras en ayunas se determinaron triglicéridos (TAG), colesterol total (Chol), moléculas solubles de adhesión intercelular-1 (sICAM-1) y moléculas solubles de adhesión vascular-1 (sVCAM-1). Asimismo se determinaron TAG y Chol postprandiales.

Resultados:

Los valores antropométricos, lípidos y sICAM-1 presentaron valores significativamente mayores en PoW frente a PrW, pero sVCAM-1 fueron similares en ambos grupos. Las concentraciones postprandiales de TAG y Chol fueron significativamente mayores en PoW que en PrW (p < 0,0001). Hubo un efecto significativo del tiempo en los TAG de PoW y PrW (p < 0,0001), mientras que el tiempo para alcanzar la concentración máxima y dicha concentración fueron significativamente mayores en PoW que en PrW. Las concentraciones de Chol mostraron una reducción significativa después de 1 h para recuperar valores similares a los basales después de 6 h en PrW pero no en PoW.

Conclusiones:

La respuesta lipídica postprandial a una comida rica en grasa y las concentraciones de las moléculas solubles de adhesión intercelular mostraron un patrón de mayor riesgo cardiovascular en las mujeres postmenopáusicas frente a las premenopáusicas. Las moléculas solubles de adhesión vascular parecen influenciadas no sólo por la edad y la menopausia, sino por otros factores como la dieta habitual (AU)
