Recommended and actual calorie intake of intensive care unit patients in a private tertiary care hospital in the Philippines.
Nutrition. 2006 Apr; 22(4):345-349.This study compared the computed nutrient requirements of geriatric patients under critical care with their actual intake within the first 3 d after admission to the intensive care unit (ICU) and determined the percentage of patients who achieved adequate intake. Fifty-eight geriatric patients who were admitted to the ICU from September to December 2002 were prospectively enrolled. Recommended and actual calorie intakes per patient were recorded and mean amount of carbohydrate, protein, and fat consumed were calculated. Student’s t test was used to compare actual with recommended nutrient intakes. Actual in relation to recommended nutrient intake was inadequate (41.5% on day 1 to 71.7% on day 3 for calories and 21.1% on day 1 to 24.3% on day 3 for protein, P < 0.001). Carbohydrate intake was low (falling from 61.9% on day 1 to 39.8% on day 3, P < 0.001) and fat intake was also low (increasing from 29.4% to 37.9% on day 3, P < 0.001). The percentage of patients who achieved adequate intake was 51.2% on day 1 and increased to 73.2% on day 3. The intake of geriatric patients in the ICU is low, with differences in actual and recommended intakes. Delivering what is recommended is still a goal to be realized in the ICU setting. (author's)
American Journal of Clinical Nutrition. 2000 Jul; 72(1):203-204.The discussion between Bray and Popkin and Willett has strong implications for the prevention of obesity, a challenge for many countries. As in China and other developing countries, in Brazil, obesity is increasing rapidly. Data from Brazil do not support the hypothesis that dietary fat plays a major role in obesity. Population-based national surveys from Brazil show that for the period of 1974-1989, obesity [defined as a body mass index (BMI; in kg/m2) >30] increased by 92% among men and by 70% among women. In 1975 the mean percentage of dietary energy from fat in Brazil was 26%. In a recent population-based survey conducted in Rio de Janeiro (there are no data available from a national survey), the percentage of energy from fat was 26.6% among men and 28% among women. Over this same time period, the prevalence of obesity in the country rose to the level found in Rio de Janeiro. Thus, a minimal increase in the percentage of energy from fat, at least in men, was associated with a striking increasing in obesity. Also, the prevalence of persons consuming >30% of total energy as fat is not high. In Rio de Janeiro, intake of >30% of total energy as fat varied from 33% among young men to 25% among old men. For women, this percentage varied from 39% to 26%. (excerpt)
