[Relationship of different dietary patterns with dyslipidemia and hypertension among middle-aged and elderly residents in Bengbu City in 2014-2015].

To understand the dietary patterns of the middle-aged and elderly in Bengbu City and to analyze the associations of dietary patterns with dyslipidemia and hypertension.During September of 2014 to September of 2015, the cluster random sampling method was used to select 860 residents aged ≥45 years old( 45-76 years old) from 6 communities of Bengbu City. They answered a well-designed questionnaire( age, gender, history of chronic disease), received physical examinations ( height, weight, waist circumference, hip circumference) and dietary survey, measured the blood lipids and blood pressure. Factor analysis was applied to determine major dietary patterns in order to analyze the associations between dyslipidemia and hypertension.( 1) Four dietary patterns was identified, namely "rice and vegetables" pattern, "animal food" pattern, "fruits and milk" pattern, "drinking" pattern. ( 2) There were significant difference of BMI between the "rice and vegetables" pattern and "animal food" pattern( P < 0. 01). There were significant difference of WC between the "rice and vegetables"pattern, "animal food" pattern and "drinking" pattern( P < 0. 01). There were significant difference of SBP between the "rice and vegetables " pattern and "drinking" pattern( P < 0. 01). ( 3) The Q4 group of "rice and vegetables" pattern and "animal food" pattern had higher proportion of protein that contributed to total energy than the Q1 group( 17. 44% vs. 13. 63%, 20. 52% vs. 17. 55%, P < 0. 05). The Q4 group of "rice and vegetables" pattern had higher energy intake of 1. 75-fold than the Q1 group. ( 4) Whether or not controlling the confounding factors of gender, age, degree of education, physical activity and BMI, a positively association was found between "animal food" pattern, "drinking" pattern and dyslipidemia by logistic regression analysis between the Q4 group with the Q1 group( unadjustment OR = 2. 665, OR = 1. 926, P < 0. 01; after adjustment OR = 1. 835, OR = 1. 447, P < 0. 05)."Animal food" pattern and "drinking" pattern may be risk factors for dyslipidemia and hypertension, reducing the intake of meat, oil in our meals may play an important role in the prevention and control of chronic diseases.
