Dietary patterns and metabolic syndrome among urbanized Tibetans: A cross-sectional study

The prevalence of metabolic syndrome (MetS) and the major dietary patterns among urbanized Tibetans are unclear. The present study aimed to investigate the prevalence of MetS among Jiarong Tibetans in Aba Plateau, identify the major dietary patterns, and evaluate their association with the risk of MetS. In this cross-sectional study on 476 subjects, 18–80-years-old, dietary intakes were evaluated using a simplified food frequency questionnaire (SFFQ). MetS was defined according to the International Diabetes Federation (IDF) guidelines. Principal component analysis was performed to assess the major dietary patterns. Multivariate logistic regression analysis examined the associations between dietary patterns and the risk of MetS. The prevalence of Mets in the population was 37.6%. Herein, three major dietary patterns were extracted: traditional Tibetan, urbanized, and healthy dietary patterns. After adjusting for potential confounders (Model 1: adjusted for sex and age; Model 2: adjusted for sex, age, smoking status, drinking situation, physical activity level and total energy intake), subjects in the highest tertile of the healthy dietary had a lower risk of MetS compared to those from the lowest tertile. Also, no significant statistical association was established between the risk of MetS and the traditional Tibetan and urbanized diet. •This is the first study of MetS prevalence and its assiciation with the dietary patterns among urbanized Jiarong Tibetan residents.
