Incidence of protein calorie malnutrition in the nursing home population.

That nutritional parameters change with age is a well-known phenomenon. Physical activity, lean body mass, and metabolic rate all decline with increasing age. There has been little work regarding the nutritional assessment of geriatric nursing home patients to determine their nutritional status and to focus attention on their nutritional needs. The purpose of this study was to assess the nutritional status of the residents of two urban nursing homes. The nutritional status of 227 nursing home residents (mean age 72.2 years) was evaluated using biochemical and anthropometric measurements. Midarm muscle circumference, triceps skinfold thickness, weight, height, serum albumin, serum pre-albumin, serum retinol binding protein, and a complete blood count with differential were obtained. The evaluation of this data indicated that there was a 52% incidence of malnutrition. This can be broken down to: 24% hypoalbuminemic malnutrition, 19% Kwashiokor-Marasmus mix, and 9% Marasmus. Twenty-eight percent of all patients were anergic, and 76% of the patients were anemic. In conclusion, there appears to be far more documentable malnutrition than anticipated or previously reported in this population.
