Food consumption and glycemic testing of adults and elderly diabetic patients from Public Health: A systematic review of assessment methods

Abstract

Aims: To map and discuss the different methods used to assess food consumption and glycemic testing of adults and elderly diabetic patients from Public Health.

Materials and methods: A total of 710 records were identified by searching databases integrated by the Virtual Health Library website, between September and October 2017. The Newcastle Ottawa scale was used for study quality assessment. A total of 8 studies met inclusion criteria for analysis. Study characteristics were extracted and synthesized to generate comparisons.

Results: Food consumption was evaluated by Food Frequency Questionnaire, 24-hour Dietary Recall, Eating Attitudes Test (EAT-26), Questionnaire On Eating and Weight Patterns (QEWP-R), and questioning the salt intake. Glucose testing methods included Postprandial Glucose, Glycated Hemoglobin (HbA1C), fasting glucose, and self-reported diabetes.

Conclusions: Most methods that access food consumption use single questionnaires, which are easy to administer and yield easily interpreted results. For glycemic testing, the majority used are conventional methods.
