Introduction: Cardiovascular disease (CVD) is one of the most important causes of mortality. Healthy diets can decrease CVDs and other chronic diseases especially in patients with type 2 diabetes. In this study, we investigate association between adherence to the modified Nordic diet and cardiovascular risk factors among patients with type 2 diabetes. Methods: This cross-sectional study was conducted among 339 type 2 diabetic patients. Anthropometric indices, blood pressure, and biochemical tests were evaluated. A validated and reliable semi-quantitative food frequency questionnaire (FFQ) was used to assess dietary intake. Nordic diet scores were calculated based on median intakes of six food groups. Results: Body mass index (BMI) was higher among participants who were in the lowest tertile of adherence to the Nordic diet (P=0.006). There was a significant association between socioeconomic status (SES) and adherence to the Nordic diet (P<0.0001). Participants who were in the top category of adherence to the diet had significantly lower levels of aspartate aminotransferase (AST) (P<0.0001). There was a significant inverse association between adherence to the Nordic diet and low density lipoprotein (LDL) levels (odds ratio [OR]=0.29 95% CI: 0.09, 0.91, P=0.025), high systolic blood pressure (SBP) levels (OR=0.35 95% CI=0.17-0.74, P=0.015), and risk of obesity (OR=0.25 95% CI: 0.10, 0.63, P=0.03). Conclusion: Results suggest that adherence to the Nordic diet is associated with reductions in the prevalence of obesity, LDL levels and blood pressure among type 2 diabetic patients. However, additional studies are needed to confirm these findings.

BACKGROUND Diabetes is a common chronic disease with many complications and is associated with the development of cardiovascular diseases (CVD). The present study aimed to investigate the association of diet quality indices and CVD risk factors among diabetic women. This cross‐sectional study was conducted in 230 Tehrani women with type 2 diabetes. A validated and reliable food frequency questionnaire was completed to assess the dietary intake. Diet quality indices were considered with respect to adherence to the Healthy Eating Index‐2010 (HEI‐2010) and Diet Quality Index‐International (DQI‐I). Anthropometric measurements, blood pressure and biochemical tests were assessed. CVD risk factors were evaluated according to the adult treatment panel III. RESULTS Patients who were in the top tertile of the DQI consumed less fat, saturated fatty acids and sodium, as well as more protein, fiber, iron and calcium (P < 0.05). Participants who were in the top tertile of diet quality indices consumed less processed and organ meat and more fruits, and vegetables. Patients in the highest tertile of HEI had lower fasting blood sugar levels (148.92 ± 6.05 mg dL−1 versus 171.30 ± 5.79 mg dL−1, P = 0.021). There was no significant association between DQI‐I, HEI and other CVD risk factors. CONCLUSION There was no association between diet quality indices and CVD risk factors among diabetic patients. © 2019 Society of Chemical Industry
