Feeding behavior pattern and glycosylated hemoglobin in people with type 2 diabetes at the beginning and end of an educational intervention

To assess the changes in food consumption pattern and glycosylated hemoglobin levels in patients with type 2 diabetes after an educational intervention. A descriptive study in people over 18 years of age with type 2 diabetes receiving the educational intervention provided by the health facilities of the Costa Rican Social Security. Sociodemographic, biochemical, and anthropometric variables were collected. Glycemic control was classified as good (≤7%), fair (7.1-8%), and poor (>8%). The usual daily diet record was used to assess the food consumption pattern based on the 11 criteria, divided into the following categories: poor compliance (0-3 criteria), fair compliance (4-7 criteria), and good compliance (8-11 criteria). Data collected were processed using SPSS version 16 software. A Student's t test was used for dependent samples. The impact of the educational intervention on metabolic control and food consumption pattern was determined using a McNemar test with a level of significance of 5% for hypothesis testing. The study sample consisted of 702 patients with a mean age of 54.5±11.6 years, 73.8% females. Mean initial glycosylated hemoglobin level was 8.8±2.14%, while final level was 7.8±1.78% (P
