“…Concerning the criteria used to group the foods obtained from collecting food intake data (step before the input of data in the multivariate techniques), 22% (n = 42) used preexisting groups from the FFQ, 14% (n = 26) adopted as a criterion the nutritional composition, 26% (n = 46) did not present any information about the used criteria, and remaining 38% (n = 75) reported: official agencies/dietary 164,172,187,191,193,198,203,204) 168,170,[174][175][176]178,179,183,184,[186][187][188][190][191][192][193]198,199,204,205) On the basis of the names of the foods 25 (42) 14 (24) 143,144,148,156,160,162,163,169,171,172,181,182,185,192,194) PCA: principal component analysis; FA: factor analysis; RRR: reduced regression rank; CVD: cardiovascular diseases; FFQ: Food Frequency Questionnaire; 24HR: 24-hour dietary recall. *Combination of two or more criteria within the same characteristic.…”

Objective: To describe the solutions adopted in the multiple steps of the use of multivariate techniques to obtain a dietary pattern (DP) concerning: the objective of the studies, the selection of the method for measuring food intake, the criteria for grouping the foods, the number of food groups used, the number of DP obtained, and the nomenclature criteria. Methods: The articles were selected from MEDLINE and Lilacs scientific databases using the following keywords: "dietary patterns" versus "factor analysis"; "principal components analysis"; "cluster analysis" and "reduced regression rank." The initial search resulted in 1,752 articles. After inclusion and exclusion criteria, 189 publications were selected. Results: The following aspects were relevant among the studies: the prevalence of the principal component analysis (PCA); the prevalence of the use of 4 to 5 DPs in the studies of association with health outcomes; the use of 30 or more food groups from the food frequency questionnaire (FFQ); the prevalence of studies that associated DPs with health outcomes and socioeconomic factors; and the heterogeneity of criteria used throughout the analytical stages of the multivariate techniques. Conclusion: The heterogeneity between the publications concentrates on the criteria for food grouping, the nomenclature, and the number of dietary patterns calculated, which varied depending on the number of food groups present in these analyses. To understand, apply, and explore in full, the multivariate techniques has become necessary in order to improve the reliability of the results and, consequently, to improve the relationships with health outcomes and socioeconomic factors.

“…The only significant positive association was reported between age and Mediterranean diet, whereas both the Western and traditional dietary patterns showed a significant negative relationship with education in both genders (P > 0.01) (24). Using cross-sectional assessment, dietary intakes of 2,510 subjects (1,121 men and 1,389 women), aged 19-70 years, from Tehran were compared with recent dietary guidelines for Americans.…”

Context:Diet is an important component of life and plays a key role in the prevention or development of non-communicable diseases. The aim of this systematic review was to determine different dietary patterns and their association with non-communicable diseases in Iranian women. Evidence Acquisition : Sources of Information: an electronic literature search was conducted on websites such as Pubmed, Science direct, Google scholar, Sid, and Iranmedex to identify original human studies, published in English and Persian up to August 2013 that included keywords or phrases relevant to the aim of this study. Results: Studies were classified into eight groups according to their objectives and outcomes, including the relationship between dietary patterns and aspects such as bone mineral density, metabolic syndrome, obesity, cardiovascular disease, cancer, markers of inflammation, hypertension, coagulation abnormalities, life style and factor analysis. Compared to healthy dietary patterns, the western and Iranian patterns were positively associated with conditions related to non-communicable diseases. The dietary approach to stop hypertension (DASH) is rich in fruits, vegetables, whole grains, low-fat dairy products, and is low in saturated fat, total fat, cholesterol, refined grains, and sweets. This diet is associated with greater high-density lipoprotein (HDL) cholesterol and lower body weight, waist circumference, fasting blood glucose, low-density lipoprotein (LDL) cholesterol and systolic and diastolic blood pressures. Conclusions: Adherence to a healthy dietary pattern is expected to secure a protective effect against non-communicable disease.

“…2 In Iran, three types of dietary patterns are identified from the recent studies: [43][44][45] Western type, high-animal fats diet, and Iranian traditional diet. Western diet is characterized by high intake of sweets, carbonated beverages, fast foods, junk foods, salty nuts/seeds, and canned foods.…”

“…The traditional diet was characterized by high intake of potatoes, beans, red meat, eggs, and dried fruits. 22,43,45 The western and animal dietary patterns have adverse effects on CVD risk. 43,44 However, Iranian traditional dietary pattern has its pros and cons in terms of the CVD prevention.…”

Cardiovascular disease (CVD) is the leading cause of death not only in industrialized and developed countries but also in developing societies. Changes in lifestyle of the population living in developing countries, which is due to the socioeconomic and cultural transition, are important reasons for increase in the rate of CVD. This observation has led to extensive body of researches on CVD prevention. In Iran, as a developing country in the Middle East, the increasing incidence of CVD has prompted the health policy-makers to emphasize on nutritional interventions as a part of the main strategies to alleviate the condition.
