The Association Between Dietary Balance Index And Metabolic Syndrome In The Population Aged 45-60 Years

Objective: Our objective was to assess the dietary quality and the prevalence of the population aged 45-60 years in Hefei, and analyze the association between dietary balance index revision and metabolic syndrome in them.Methods: We recruited people who accept physical examination in hospital health management center in 2013, and they were born from 1953 to 1968. The total number of them was 580. Objects were divided into two groups: MS group and control group. Using dietary balance index revision analyze the dietary quality of the objects. Questionnaire includes basic information, physical activity, food intake(using semi-quantitative food frequency), anthropometric indicators(height, BMI, waist circumference etc.) of the objects. Laboratory indicators include fasting blood glucose, blood lipids and so on. The t test or analysis of variance was used to describe mean differences about height, BMI, waist circumference, hip circumference, waist-hip ratio between two groups. One-Way ANOVA was used to compare difference between two groups with hypertension, hyperlipaemia, coronary heart disease, fatty liver, type 2 diabetes. Mann-Whitney U test was used to compare difference about metabolic equivalent, blood pressure, fasting plasma glucose, triglycerides, HDL cholesterol, scores of DBI-07 and diet scoring between two groups. Logistic regression was used to assess the relationship between scores of DBI-07 and MS, diet scoring and MS. Multivariate logistic regression was used to assess the relationship between DBI-07 and MS.Results: The result of the survey show that 75 males with MS, the prevalence was 12.9%; 38 females with MS, the prevalence was 6.5%. In this group of people, the quality of dietary intake is not balanced and with a low dietary intake in generally. Comparison of Scores of DBI-07 between MS group and control group: 1. the scoring of LBL-DBI,HBL-DBI,DQD-DBI had obvious statistical significance(P < 0.01). LBL-DBI, HBL-DBI, DQD-DBI was a risk factor for MS, the odds ratio was 1.034(95% confidence interval(CI):1.007-1.062), 1.078(95% CI:1.029-1.130), 1.054(95% CI: 1.027-1.082) respectively.2.scoring of fruits and vegetables, oil, salt and alcohol, water had statistical significance(P < 0.05). Scores of fruits and vegetables was a protection factor, but scores of oil, salt and alcohol, water were risk factors for MS, the odds ratio was 0.598(95% CI:0.531-0.672), 1.216(95% CI:1.115-1.326) and 1.132(95% CI:1.019-1.257) respectively. After adjusting for potential confounders, LBL-DBI, HBL-DBI, DQD-DBI were still risk factors for MS.Conclusion: Inadequate dietary intake, excess dietary intake, dietary intake of imbalances would result in increased risk of metabolic syndrome. Therefore, DBI- 07 might be associate to MS. Preventing the happening of the MS, we need attaches great importance to the overall diet quality.
