Abstract
BackgroundThis study was conducted to identify dietary patterns and evaluated their association with biochemical blood profiles and body weight among adults with type 2 diabetes mellitus.MethodsThis was a cross sectional study conducted among 400 patients with type 2 diabetes mellitus in Tehran from March to August 2013. Biochemical blood profiles, socio-demographic, lifestyle, anthropometric measurements, and dietary data were obtained. Dietary data from food frequency questionnaire were used to derive dietary patterns. Factor analysis was conducted to ascertain the dietary patterns, and analysis of covariance was fitted to assess the relation between blood profiles, body weight and adherence to dietary patterns.ResultsThree dietary patterns by factor analysis were identified, Vegetable & Poultry, Western and Semi-healthy. After control for potential confounders, body mass index (b = −0/03, p < 0.05) were negatively associated with vegetable and poultry dietary pattern. Conversely, total cholesterol (b = 0.004, p < 0.01) and fasting blood glucose (b = 0.014, p < 0.05) were positively associated with western dietary pattern. A dietary pattern labeled as semi-healthy pattern was found to be positively related to HDL-cholesterol (b = 0.006 p < 0.01). Associations between semi-healthy pattern, LDL-cholesterol (b = −0.120 p < 0.05) and waist circumference (b = −0.020, p < 0.05) were negative.ConclusionAdherence to Vegetable & Poultry dietary pattern was favorably related to body weight, semi healthy related to lower LDL and higher HDL cholesterol whereas western related to higher fasting blood glucose and total cholesterol. Further studies are necessary to confirm the benefits of the dietary patterns for diabetes.
Highlights
This study was conducted to identify dietary patterns and evaluated their association with biochemical blood profiles and body weight among adults with type 2 diabetes mellitus
In a prospective study of men; it was suggested that they are good sources of dietary fiber with a positive effect on concentration of Total Cholesterol [25], and contributes to improved glycaemic control but the results of our study showed that consumption of legumes had direct correlation to a dietary pattern with the cholesterol and blood glucose increase, as most of the legumes intake was attributable to intake lentils, peas or beans stew together with meat
This study identified three major dietary patterns
Summary
This study was conducted to identify dietary patterns and evaluated their association with biochemical blood profiles and body weight among adults with type 2 diabetes mellitus. Some studies have described the associations between diabetes mellitus and diet, in terms of single nutrients [2,3,4] or food groups [5]. The terms of dietary pattern has been recommended as an approach used to investigate diet-disease relations. The dietary pattern approach is a powerful means for summarizing nutrient and food intake to depict the whole diet [6,7]. The aim of the present study was identified the dietary patterns and investigated dietary patterns in relation to biochemical blood profiles and body weight among adults with type 2 diabetes mellitus
