Resumen:
Vitamin D deficiency is common in institutionalized elderly people. Correction of vitamin D deficit could reduce morbidity incidence and financial costs. Argentina has high prevalence of vitamin D insufficiency but in Spain traditionally, it had been considered not a common problem because of the high sun irradiation. Vitamin D status in women older than 65 years, living in similar social status institutions from geographic cities having similar sun irradiation index: Lleida (Spain) (43 0NL) and a suburban Buenos Aires (BA) area (340SL) were compared. During the end of summer 81 women (50 from Lleida, 31 from BA) were studied. None of them received vitamin D supplements or any medication that could affect bone metabolism. A dietary survey was recorded (calcium and vitamin D consumption) and fasting serum was obtained. Results (mean ± SD) in Lleida vs. BA, respectively were as follows: Hemoglobin (g/dl): 12.6(2.4 vs. 13.1(1.4; total protein (g/dl): 6.8(0.3 vs. 6.8(0.6; albumin (g/dl): 3.73(0.11 vs. 3.51(0.35; 25HOD3 (ng/ml) (RIA, Diasorin): 11 ± 6 vs. 12(6. A total of 50% in Lleida and 43% in BA had 25OHD3 lower than 10 ng/ml; and increased to 76 y 71%, respectively, when 15 ng/ml was the cut off. Sun exposition was low in both groups. Greater fish consumption and lower red meat consumption was in Lleida than in BA. Dairy products consumption was similar (calcium intake = 800 mg/d), Vitamin D intake was 1.7 (g/day in Lleida (dairy products are not fortified) and 4 (g/day in BA (fortified dairy products). Conclusions: Vitamin D deficiency was important in both population groups. Correction deficit would be imperative in order to prevent a great impact on bone health.
