Dietary adherence to glycemic load and food insulin index

<p dir="ltr">An Adherence Score Sheet (ASS) was developed to quantify dietary adherence to glycemic index, glycemic load and food insulin index principles. 67 three-day food records of patients with diabetes who received nutrition education were scored using the ASS. To determine inter-rater reliability of the ASS, Intraclass correlation (ICC) and Bland-Altman plots were used to demonstrate the amount of agreement between ASS from two independent raters. To determine concurrent validity, ICC and Bland-Altman plots were used to determine the amount of agreement of ASS score from Rater 1 [test method] vs ASS scores obtained from a dietary analysis (DA) program [reference method].</p><p dir="ltr">The adherence scores obtained from the ASS were used to determine the level of dietary adherence to personalised nutrition education (PNE) based on glycemic index (GI), glycemic load (GL), and food insulin index (FII) principles and whether adherence was associated with improved blood glucose concentrations.<b> </b>In a retrospective cohort the 67 files of patients who received PNE were used. The patients completed 3-day food and blood glucose records at three points over 90 days. Glycated hemoglobin values were compared between time points. The adherence score sheet (ASS) was used to determine their adherence to PNE and the main meal adherence classification (MMAC). A one-way repeated measures ANOVA was used to assess the changes over time. A chi-square test determined the association between the MMAC and blood glucose levels falling within the targeted ranges. Correlations between dietary adherence and mean blood glucose levels and glycated hemoglobin were examined using Pearson’s product–moment correlation.</p><p dir="ltr"><br></p>
