Impacto da atençäo nutricional na reduçäo dos níveis de colesterol sérico de pacientes atendidos em serviços públicos de saúde / Impact of nutritional counseling in reducing serum cholesterol in public health service patients

RESUMO

OBJECTIVE: To assess the impact of nutritional attention on the lipid profile and nutritional status of hypercholesterolemic patients attended in health centers of Belo Horizonte. METHODS: Using nutritional attendance patient record cards from two health units, the evolution of the lipid profile and the nutritional state (BMI) was monitored of 96 hypercholesterolemic patients who received diet. The patients were appraised at the following moments: initial (1st consultation), after 3 months (2nd consultation) and last consultation (variable for each patient). RESULTS: On the first attendance, 44,4 percent of the patients presented not only high total cholesterol and LDL-c, but also hypertriglyceridemia and 70.3 percent were overweight or obese, but most patients (75.6 percent) presented adequate HDL-c levels. There was significant reduction in the BMI, total cholesterol, LDL-c values (p < 0.01) and also in the triglyceride levels (p < 0.05) in the first three months, without alteration in the HDL-c levels. A significant reduction (p < 0.01) was observed in the frequency of individuals with high cholesterol (from 89.6 percent down to 47.9 percent), high and very high LDL-c (from 82.6 percent down to 45.7 percent), as well as high and very high triglyceride (from 43.6 percent down to 16.7 percent). The observed reduction in frequency of the low HDL-c was statistically meaningless. CONCLUSION: This study evidences the effect of the nutritional attention on lipid profile in hypercholesterolemic patients, reinforcing the need for a multiprofessional team to attend them at the public health services
