Abstract
BackgroundEpidemiological evidence concerning dietary fiber on newly-diagnosed type 2 diabetes mellitus (T2DM) is sparse. Therefore, the purpose of this study was to investigate the relationship between dietary fiber intake and newly-diagnosed T2DM in a middle-aged Chinese population.MethodsUsing data from the Hangzhou Nutrition and Health Survey collected between June 2015 and December 2016, we investigated the associations between dietary patterns and the risk of chronic non- communicable diseases. Anthropometric measurements and samples collection for biochemical assays are conducted by the well-trained staff and nurse, respectively. Multivariable logistic regression analysis was used to analyze the effect of dietary fiber intake on the risk of newly-diagnosed T2DM in crude and adjusted models.ResultsAmong 3250 participants, 182 (5.6%) people were identified as newly-diagnosed T2DM. Pearson correlation coefficients revealed a significant inverse association of total dietary fiber with BMI, SBP, DBP, HbA1c and LDL-C in all participants, participants with and without T2DM (P < 0.05). Compared with the study participants in the first quartile (Q1, the lowest consumption)of dietary fiber intake, participants in the fourth quartile (Q4) had a lower prevalence of newly-diagnosed T2DM(OR = 0.70; 95%CI:0.49-1.00; P < 0.05), after adjustment for potential confounders.ConclusionsIn this middle-aged Chinese population, higher intake of dietary fiber was significantly associated with lower risk of newly-diagnosed T2DM. However, our findings need to be confirmed in future large-scale prospective studies.
Highlights
Type 2 diabetes mellitus(T2DM) is a major non-communicable chronic disease that affects the health, economy and well-being of populations worldwide [1]
In view of the current paucity of data in this area, we took advantage of a large population-based cross-sectional study performed in Eastern China, to determine the association between dietary fiber intake and the risk of newly-diagnosed type 2 diabetes mellitus (T2DM) in a middle-aged population
Our results indicated that higher dietary fiber intake was significantly associated with reduced risk of newly-diagnosed T2DM
Summary
Type 2 diabetes mellitus(T2DM) is a major non-communicable chronic disease that affects the health, economy and well-being of populations worldwide [1]. During the past several decades, dietary factors have been shown to play an important role in prevention and management of T2DM [6]. To the authors’ knowledge, no previous epidemiological study has been conducted to investigate dietary fiber intake in relation to newly-diagnosed T2DM risk in the Chinese population. In view of the current paucity of data in this area, we took advantage of a large population-based cross-sectional study performed in Eastern China, to determine the association between dietary fiber intake and the risk of newly-diagnosed T2DM in a middle-aged population. Epidemiological evidence concerning dietary fiber on newly-diagnosed type 2 diabetes mellitus (T2DM) is sparse. The purpose of this study was to investigate the relationship between dietary fiber intake and newly-diagnosed T2DM in a middle-aged Chinese population
