Healthy dietary habits can prevent cardiovascular diseases (cvd). the aim of the present study was to investigate the association between dietary patterns and predicted risk of cvd development using framingham risk score (frs) in iranian population over 6 y of follow-up.
Methods
In this prospective study 2333 individual aged 30-75 y with a 10-y predicted risk<10% and without a cvd diagnosis at baseline were recruited from participants in the third survey of tehran lipid and glucose study. usual dietary intake was assessed using a validated semi-quantitative food frequency questionnaire. dietary patterns were identified using factor analysis. the risk of developing cvd was evaluated using frs questionnaire. the association between dietary patterns and risk of development of cvd was evaluated using binary logistic regression models.
Results
Three major dietary patterns were identified which explained 32% of total variance in dietary intake of participants. the healthy dietary pattern was characterized by high intake of fruits, fruit juices, vegetables, liquid oil, nuts and lower intake of refined grains. the western dietary pattern was characterized by high intake of fast foods, soft drinks, sweets and sugars and red meat, organ meat and egg. the traditional dietary pattern was characterized by high intake of legumes, vegetables and low intake of high-fat dairy products. after adjustment for all confounding factors, participants in the highest tertile of the healthy dietary pattern had a lower risk of cvd development (or: 0.67; 95% ci: 0.51-0.87, p-trend: 0.003).
Conclusion
Our findings in a large cohort of iranian population confirm the current recommendation regarding consuming healthy dietary pattern for primary prevention of cardiovascular diseases.
