Abstract

Introduction

Cardiovascular diseases (cvd) are the cause of 31% deaths worldwide. lifestyle, especially diet is effective on cvd incidence. in previous studies the association of dietary pattern and the risk of cvd was examined

Methods

At baseline (2007–2008), 9704 individuals aged 35–65 years enrolled in the mashad cohort study. during the follow-up through january 2015 to april 2016, the cardiovascular diseases of participants (n= 240) were confirmed by cardiologist. healthy, non-symptomatic individuals (n= 9464) were considered as the control group. diet was measured with a 65 item food frequency questionnaire of mashad study.

Results

We identified two major dietary patterns: western pattern (high intake of sugars, meat products and carbonated beverages) and high protein, high fiber pattern (high intake of vegetables, fruits and dairy products) by factor analysis. the odds ratio (or) and 95% confidence intervals of total cardiovascular disease in the highest versus lowest quintiles of the western pattern were 2.33 (0.81 – 6.67) p for trend= 0.0001. the ors of cardiovascular disease in the highest versus lowest quintiles of the traditional pattern were 0.85 (0.54 – 1.34) p for trend= 0 .0001.

Conclusion

Unhealthy dietary intake can increase the cvd risk. iranian population should be encouraged to choose healthy pattern to prevent rising epidemic of cardiovascular disease.
