ABSTRACT
The diet potential for increasing serum total cholesterol level (TOTAL-C) and developing atherosclerosis has been associated with intake of saturated fat and cholesterol. The objective of this study was to identify the association between food frequency consumption and TOTAL-C. These observations were collected during a cross-sectional examination, in a representative sample of 1045 adults, both sex, of 20 years of age and over, from Cotia City, São Paulo, Brazil. The variables studied were food consumption (examined by food frequency questionnaire), TOTAL-C, and other variables. The association between TOTAL-C levels among the population studied was analyzed by multiple linear regression model (step-wise-forward) adjusted by age, gender, body mass index (BMI), waist to hip ratio (W/H), educational level, family income, physical activity, smoking and alcohol consumption. Consumption of chicken meat, red meat, pork, liver and processed meat, eggs, dairy food, showed significant and positive relationship with TOTAL-C (15.5, 14.0, 10.6, 17.1, 8.2, 4.4) mg/dL, respectively. Fruit and vegetables consumption were inversely related to TOTAL-C (-8.2, -7.2) mg/ dL, respectively. We observed that as food consumption contributes to TOTAL-C concentration variation, risk factors for coronary heart disease may be lowered by healthy food habits.
RESUMO
O potencial da dieta em aumentar níveis de colesterol sérico e promover aterosclerose está diretamente relacionado com o seu conteúdo de colesterol e gordura saturada. O propósito deste estudo foi identificar a associação entre a freqüência de consumo alimentar e níveis séricos de colesterol. Trata-se de um estudo transversal, em uma amostra representativa de 1 045 adultos de ambos os sexos, de 20 anos ou mais, residentes no Município de Cotia, São Paulo, Brasil. As variáveis estudadas foram consumo de alimentos através da freqüência de consumo alimentar, o nível de colesterol sérico, e outras variáveis. Foi elaborado modelo de regressão linear múltipla (step-wiseforward) para colesterol total ajustados por idade, sexo, índice de massa corpórea, relação cintura quadril, nível educacional, renda familiar, atividade física, tabagismo, etilismo. Os consumos de carnes de aves, carne bovina, carne suína, vísceras e carnes processadas, ovos e leite e derivados foram associados positiva e significativamente com os níveis de colesterol total em (15.5; 14.0; 10.6; 17.1; 8.2 e 7.2) mg/dl, respectivamente. O consumo de frutas e hortaliças foi associado inversa e significativamente com os níveis de colesterol total em -8.2 e -5.5 mg/dl, respectivamente. Os hábitos alimentares contribuem para as variações na concentração dos lipídios séricos, redução nos riscos para doenças cardiovasculares podem ser alcançados por meio de hábitos alimentares saudáveis.
