Malnutrition in the hospital is not a new or rare problem, however, it
is often unrecognized. In order to determine the baseline nutritional
characteristics of recently hospitalized patients, we assessed the nu
tritional status of all medical in-patients between April and December
1994 in a large hospital in the province of Buenos Aires. One hundred
and seventy patients were derived from the Internal Medicine ward and
176 patients from the General Surgery ward. Surgery patients were you
nger (median: 46 years vs 58 years of the Medicine patients). Among Me
dicine patients, cardiovascular and respiratory afflictions were the m
ost common (30%), while gastrointestinal disorders were more often see
n in Surgical patients (71%). A weight loss of more than 10% (%WL) was
found in 12% of the Medicine and Surgery patients and a body mass ind
ex (BMI) of less than 19 kg/m(2) was observed in about 5% of both grou
ps. Ten percent of the Medicine patients and 14% of the Surgery patien
ts were overweight. A mid-upper arm muscle circumference (MUAMC) less
than the fifth percentile was found in 11% of the Medicine patients bu
t in only 3% of the Surgery patients. These results suggest that this
population of recently hospitalized patients is at high-risk for medic
al complications. Therefore, early nutrition assessment and appropriat
e nutrition intervention are required to improve clinical outcome and
help reduce the cost of health care.
