This study has been done in order to determine the relationship between the kind of protein intake (plant & animal protein), and different risk factors of cardiovascular diseases such as systolic and diastolic blood pressure (SBP,DBP), Total cholesterol (Cho), Triglycerid (TG), fasting blood sugar (FBS) and BMI and also to determine the relationship between protein intake and income and level of education.
This is a cross- sectional study, which has been done on underevaluation sample in the National Program of Cardiovascular Diseases Prevention and Control in Isfahan (Isfahan Healthy Heart Program). The first stage of this program was performed in 2000 in Isfahan, and this research has been done on the findings of this stage.
4187 persons from the urban population of Isfahan from both sexes (51.9 % women and 48.1 % men) aged > 19 years have been studied.
Sample persons filled the food frequency questionnaire and the main risk factors such as BMI, FBS, TG, Cho, DBP, and SBP obtained by measuring height, weight, blood pressure and serum sample analyzing. Also the income, and level of education of samples were asked. The relationship between the kind of plant and animal protein intake and risk factors, income and level of education were obtained by regression analysis.
Among the sources of plant protein, the consumption of soy protein is lower than other sources and from the animal protein, the consumption of fish is lower than other proteins. There is no relationship between consumption of plant and animal proteins and risk factors of CVDs in men group. (P>0.05), but in women group BMI, FBS, Cho and SBP have a negative relationship with plant portions (P<0.05) and Cho, DBP, and SBP have a negative relationship with the consumption of animal proteins (P<0.05). Also level of education has a direct relationship with the consumption of animal proteins (P=0.000), while the level of income has not any relation with the kind of protein (P>0.05). The consumption of plant proteins has a reversed relation with the level of education and the income in both men and women (P=0.000)
Obtained results necessitates to do necessary actions in order to promote the consumption of plant sources for controlling CVDs, and even these actions seem to be necessary to do for the persons with higher level of education, because although the level of educations of these persons increased, but the consumption of this kind of protein decreased. Also the equilibrium of the consumption of protein resources should be considered; because today in our community likes most of the developing communities, the consumption of animal protein resources is increasing.
