Abstract
in English, Spanish

Introduction: Magnesium is an essential micronutrient for human body, and its deficiency has been associated with risk of non-communicable diseases.

Objective: Assessment of magnesium status, and evaluation of the frequency of magnesium deficiency in a group of healthy adults.

Methods: Plasma and erythrocyte magnesium levels, and magnesium intake were determined in 115 students (55 women and 60 men), from a public university in Brazil.

Results: The medians of magnesium concentration in plasma (0.76 mmol/L), erythrocyte (1.97 mmol/L), and of dietary daily intake (8.84 mmol/d) were low. Forty two percent of participants had plasma or erythrocyte magnesium below the limit of 0.75 and 1.65 mmol/L, respectively. A high percentage showed high probability of inadequate magnesium intake.

Conclusions: There was a high frequency of subclinical magnesium deficiency in the adults assessed, that could be related to low dietary magnesium intake.

INTRODUCCIÓN: El magnesio es esencial, y su deficiencia ha sido asociada a mayor riesgo de enfermedades crónicas.

Objetivos: Evaluar el estado de nutrición de magnesio y su ingesta en adultos sanos, y determinar la frecuencia de su deficiencia en esta población. MÉTODOS: Fueron evaluados 115 adultos estudiantes de una universidad pública en Brasil, y se determinó la ingesta dietética y los niveles de magnesio en plasma y eritrocitos.

Resultados: Las medianas de distribución de magnesio en plasma (0,76 mmol/L), en eritrocitos (1,97 mmol/L), y la ingesta de magnesio (8,84 mmol/d) fueron bajas. Un 42% de la muestra tuvieron concentración de magnesio en plasma o eritrocitos por debajo de los respectivos 0,75 mmol/L y 1,65 mmol/L. Un alto porcentaje de ellos exhibió probabilidad de ingesta de magnesio inadecuada.

Conclusiones: Se observó una alta frecuencia de deficiencia de magnesio subclínica en los adultos evaluados.
