[Nutritional study of alcoholics with specific reference to calcium and phosphorus]. / Estudio nutricional en alcohólicos con particular referencia a calcio y fósforo.

We performed a nutritional study of 80 alcoholic males at least 15 days after an acute episode of alcoholic intake. 43 patients were intermittent drinkers with mean age 37.9 years and 37 patients were continuous drinkers with mean age 440.30 healthy subjects were studied as controls. Body mass index was 23.7 (range 19.2-37.9) in intermittent drinkers compared to 23.1 (range 18.1-29.8) in continuous drinkers (NS). Wine was the main alcoholic beverage in 70% and 89%, respectively. Mean daily alcohol intake was 170 g for 17 years and 358 g for 23 years, respectively. Mean caloric intake and % of calories from alcohol were 3387 and 42% for intermittent compared to 4271 and 66% for continuous drinkers, respectively. Daily calcium intake was 757 g and 774 g in each group. Alcoholic beverages supplied 16% and 34% of calcium intake, respectively. The intake of phosphorus was adequate. Alcoholic subjects did not manifest anemia or hypoalbuminemia, compared to controls. The present study fails to disclose significant caloric and protein undernutrition in alcoholic subjects. However, the intake of calcium is inadequate and a high percentage of it is provided by alcoholic beverages. This deficiency in conjunction with alcoholic damage to intestinal mucosa may lead to osteopenia in alcoholic patients.
