RESUMO

BACKGROUND AND AIMS: Despite evidence of the lipid-lowering effect of plant sterols among adults with hypercholesterolemia, data regarding phytosterol use in children are limited. In this paper, we examined the effects of daily consumption of a phytosterol-enriched milk compound on the lipid profiles of Brazilian children and adolescents with dyslipidemia. METHODS AND RESULTS: This was a randomized, double blind, crossover clinical trial. Twenty eight dyslipidemics outpatients (aged 6-9 years) from an University Hospital were randomly allocated to control or intervention group. The intervention group received milk enriched with 1.2 g/day of plant sterol and the control group received the equivalent amount of skim milk during the period of 8 weeks. Changes from baseline in the mean lipid profile, including total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), and triglyceride (TG) concentrations. Serum lipid profiles, glucose levels, dietary and anthropometric data were determined at weeks 0, 4, 8, 16, and 20. Details regarding the safety and tolerance of phytosterol were obtained, using an open-ended questionnaire. Intention-to-treat analysis were performed, using the proc mixed procedure in SAS. After 8 weeks, the mean concentrations of TC and LDL-C were significantly reduced in the intervention group as compared to the control group with reductions of 5.9% (p = 0.09) and 10.2% (p = 0.002), respectively. In addition, TG concentrations were reduced by 19.7% (p = 0.09). No serious side effects were reported during the study. CONCLUSION: Our results confirm that plant sterols are an effective and safe treatment of infantile dyslipidemia. TRIAL REGISTRATION: RBR-3h7f9k.

RESUMO

OBJECTIVE: To evaluate the nutritional status of patients on hospital admission, identify the length of hospital stay and identify the parameters of nutritional assessment that are most closely related with the length of stay (LOS). METHODS: A cross-sectional study of 278 hospitalized patients evaluated patients' nutritional status in the 48 hours after admission and their LOS after discharge. Anthropometric and biochemical parameters, related to nutrition status were analyzed, such as: weight, height, arm circumference (AC), waist circumference (WC), triceps skinfold thickness (TST), mild arm muscle circumference (MAMC), albumin (Alb) and hemoglobin (HB). Body mass index (BMI) was used to classify the nutritional status. All the nutritional factors except type of disease, gender and age were associated with LOS. The chi-square, Student-t, Mann-Whitney, Kruskal-Wallis and binary logistic multivariate tests were used in the statistical analyses. RESULTS: The majority of patients was male (53%), elderly (56%) and had neoplasm (19.4%). Undernutrition was higher in the elderly (p < 0.05) and neoplasm patients (p < 0.05), overweight or obese patients were more likely to suffer from cardiovascular diseases (p = 0.001). Average LOS was 14.7 days (± 12.5), longer in neoplasm patients (p < 0.05) and in elderly ones (p < 0.05), and also was 3 times longer in males (p < 0.0001). Among the nutritional parameters, patients with AC under 25 cm had higher LOS (p < 0.05), but only in women could it be considered a marker, increasing LOS 2.8 times. BMI less than 20 kg/m(2) increased LOS 2.1 times, and biochemical data (Alb and HB) do not contribute. In the multivariate analyses, male gender and TST depletion were the significant factors, which together best explained the lengths of hospital stay. CONCLUSION: LOS was associated with disease, gender, age and nutritional status. We can highlight two anthropometric analyses: first, AC can be used in women as a marker of longer LOS and second TST is the best overall predictor of longer hospital stay.
