Background: In most cases, atherosclerotic cardiovascular disease (ACVD) is preventable through primary prevention and control of traditional risk factors, such as smoking cessation, regular physical activity, and adherence to healthy dietary patterns. The assessment of diet quality of ACVD patients would be important for a dietary intervention.Objectives: This study aimed to evaluate diet quality of ACVD patients and its association with clinical conditions. Methods: This cross-sectional study was nested within a randomized clinical trial entitled "Programa Alimentar Cardioprotetor Brasileiro." Baseline data of 80 patients from Pelotas, Brazil, were obtained. Food consumption was assessed using 24-h food recall and the Revised Diet Quality Index (IQD-R). Data on smoking status and comorbidities were reported by the patients during medical history taking. To analyze the associations between IQD-R and clinical variables, unpaired Student's t-test or the analysis of variance was performed. The significance level was 5%.Results: Most of the sample consisted of men (66.5%), elderly individuals (52.50%), patients with hypertension (78.75%), dyslipidemia (58.75%), and overweight (73.75%). The average IQD-R score was 56.7 ± 12.6 points. Better quality of diet was observed for patients with diabetes compared to those without diabetes (61.1 ± 11.8 versus 54.0 ± 12.6 points; p=0.014). Conclusion:There is a need to improve diet quality of ACVD patients. Patients ACVD and diabetes had better diet quality compared to those without diabetes.

Resumo O presente estudo investigou a associação entre o consumo de bebidas açucaradas e variáveis antropométricas e bioquímicas em análise transversal, realizado com dados secundários referentes à primeira consulta do ensaio clínico randomizado Dieta Cardioprotetora Brasileira (2013-2014). Foram coletados peso, altura, circunferência da cintura, perfil lipídico e glicemia de jejum e dados de um recordatório alimentar de 24 horas. Diferenças entre o consumo e não consumo de bebidas açucaradas foram avaliadas pelo teste T de student. Para analisar a associação entre o consumo de bebidas açucaradas e fatores bioquímicos e antropométricos foi utilizado o teste qui quadrado. A amostra foi de 2.172 indivíduos, sendo a maioria homens (58,5%), idosos (63,6%), do nível econômico C (57,3%), com ensino fundamental (45,8%) e com excesso de peso (62,7%). Houve associação significativa entre o consumo de bebidas açucaradas e maior valores de índice de massa corporal (p=0,029), circunferência da cintura (p=0,004) e triglicerídeos (p=0,023). Esses resultados reforçam a necessidade de intervenção nutricional quanto ao consumo de bebidas açucaradas como parte do tratamento dietético desta população.
