LB014-SUN AN EVALUATION OF WATER BALANCE IN PREGNANT WOMEN IN GREECE

Results: The questionnaire indicated probable magnesium deficit in 25% of all patients, and almost certain magnesium deficit in 4% of patients. The recorded scores correlated positively with age of patients (P= 0.003) and negatively with urine magnesium (P< 0.001). Plasma magnesium was compared in groups with and without supplementation (Magnesia and control group, respectively) before and after 3 weeks of investigation (Magnesia group before: 0.814±0.08 mmol/l, Magnesia after 3 weeks 0.977±0.15 mmol/l, P< 0.001, controls before 0.87±0.16; controls after 3 weeks 0.94±0.15, ns.). Conclusion: Risk of magnesium deficiency was found in 29% patients by adjusted questionnaire. The questionnaire scores significantly correlated with age and magnesium concentration in urine. The significant elevation of plasma magnesium concentration indicates good bioavailability of magnesium in tested mineral water. Supported by grant IGA MZ CR NT/13536 4/12.
