Association of Dietary Inflammatory Index(DII) and Metabolic Syndrome in the Elderly over 55 years in Northern China
Abstract We assessed the association between the Dietary inflammatory index (DII) and the development of metabolic syndrome in the elderly over 55 years in Northern China. The data of 1936 Chinese adults aged 55 and over from a community-based neurological disease cohort study from 2018 to 2019 were analyzed. Multiple logistic regression and restricted cubic splines regression were used for analysis, and social demographics, lifestyle, health-related factors were adjusted. In the fully adjusted model, the risk of metabolic syndrome increased by 1.28-fold in people with a pro-inflammatory diet. When we divide the metabolic syndrome by its components, high pro-inflammatory diet and hyperglycemia, triglycerides, hypertension, and abdominal obesity. We failed to observe a significant association between a high pro-inflammatory diet and HDL-C; However, these associations are moving in the expected direction. At the same time, the results of BMI subgroup analysis showed that with the increase of DII, obese people are at increased risk of metabolic syndrome, hyperglycemia, high triglycerides, hypertension, and abdominal obesity. Also in overweight people, the increase in DII is accompanied by an increased risk of hyperglycemia and abdominal obesity. Higher inflammatory diet is related to metabolic syndrome, hypertension, hyperglycemia, abdominal obesity, and hypertriglyceridemia. Further research is needed to confirm the role of inflammation and diet in the development of metabolic syndrome; however, it is desirable to reduce the dietary components associated with inflammation.
