RESUMO

OBJECTIVES: In this study, we aimed to elucidate the association between taste acuity and serum zinc concentration in patients with type 2 diabetes. METHODS: We enrolled 29 patients who were hospitalized and asked them to attend a 2-week diabetes education program. Fasting blood samples were obtained on the morning of the first day and 2 weeks after hospitalization. The acuity of sweet, salty, sour or bitter taste was evaluated by a filter-paper disc method. Correlations among taste acuity, glycemic control and serum zinc concentration were analyzed using the Spearman rank correlation coefficient. RESULTS: The following parameters (mean ± standard deviation) were improved after 2 weeks' hospitalization: taste acuity (sweet: 3.5±1.0 to 2.9±1.1; salty: 3.3±1.1 to 2.6±1.0; sour: 3.6±1.2 to 2.7±0.8; and bitter: 3.3±1.3 to 2.7±1.1; all p<0.001); glycemic control (fasting plasma glucose, 9.4±3.0 to 7.1±1.8 mmol/L, and glycoalbumin, 26.3±7.7 to 22.7±5.9 %; both p<0.001); and serum zinc concentration (1.2±0.2 to 1.3±0.2 mmol/L; p<0.001). Sour and bitter taste acuity were significantly associated with serum zinc concentration (sour, r=-0.50, p=0.005; bitter, r=-0.40, p=0.033). CONCLUSIONS: Glycemic control, serum zinc concentration and taste acuity were improved after the short-duration education program. Sour and bitter taste acuity were significantly associated with serum zinc concentrations.

RESUMO

Skipping breakfast or irregular breakfast is associated with poor glycemic control. However, a relationship between the timing of dinner and glycemic control in people with type 2 diabetes remains indefinite. Therefore, we investigated the relationship between late-night-dinner and glycemic control in people with type 2 diabetes. We performed questionnaire survey for lifestyle factors in this cross-sectional study. We defined having dinner later than eight pm as late-night-dinner. We examined the differences in clinical and metabolic parameters between those who have late-night-dinner and those who do not have. We also examined the relationship between late-night-dinner and HbA1c, using multiple regression analysis. Ninety-five people (23.2%) had a late-night-dinner, among 409 people with type 2 diabetes. Metabolic parameters (mean (SD) or median (interquartile range)) of people with late-night-dinner were worse than those of without, including body mass index (BMI) (24.4 (4.0) vs. 23.2 (3.4) kg/m2, p = 0.006), triglycerides (1.5 (1.1-2.1) vs. 1.2 (0.8-1.7) mmol/L, p < 0.001), HDL-cholesterol (1.4 (0.4) vs. 1.6 (0.4) mmol/L, p = 0.004) and hemoglobin A1c (58.1 (13.3) vs. 55.2 (10.2) mmol/mol, (7.5 (1.2) vs. 7.2 (0.9) %), p = 0.023)). Late-night-dinner (standardized regression coefficient = 0.13, p = 0.028) was associated with hemoglobin A1c after adjusting for age, BMI, sex, duration of diabetes, smoking, exercise, alcohol, snacking after dinner, nighttime sleep duration, time from dinner to bedtime, skipping breakfast, and medication for diabetes. Late-night-dinner is independently associated with poor glycemic control in people with type 2 diabetes.
