RESUMEN
Background: This study aimed to investigate the effectiveness at 1 and 3 months of using a smaller rice bowl for diet therapy among Japanese men with type 2 diabetes. Methods: A parallel-group randomized controlled trial was conducted at a medical clinic in Japan. The participants were men with type 2 diabetes mellitus, aged 20-80 years, with glycosylated hemoglobin <8.5%, and who ate rice one or more times per day at home. The intervention group (36 men) received a small rice bowl from which to eat the usual diet therapy, and the control group (38 men) received only the usual diet therapy. Results: The changes in weight and body mass index among the intervention group at 1 month were significantly higher than those in the control group. There were no significant differences between the two groups at 3 months. Conclusion: The effects of using a small rice bowl were minor and short-term.

RESUMEN
AIMS: We investigated the impact of actual waiting time and perceived waiting time on treatment satisfaction in patients with diabetes receiving outpatient care. METHODS: Three hundred and thirty-six outpatients diagnosed with diabetes mellitus or impaired glucose tolerance were selected and the time they spent in reception, blood collection, consultation, and accounting were recorded to measure the time they spent waiting in the hospital (actual waiting time). Simultaneously, we conducted a questionnaire survey that included questions on their perceptions of the waiting time (perceived waiting time) and satisfaction with treatment (DTSQ). RESULTS: No significant relationship was found between actual waiting time and DTSQ score, although associations were observed with perceived waiting time. The patients who felt the overall waiting time was long scored 23.0, those who felt it was short scored 26.0, and those who felt it was very short scored 34.0, with those who felt the waiting time was long having a significantly lower score (p = 0.004, p < 0.001, respectively) and those who felt it was short having a significantly lower score than those who felt it was very short (p = 0.008). In addition, more patients who felt the waiting time was long expressed dissatisfaction with the responses of doctors and staff than those who felt the waiting time was short. CONCLUSIONS: These results suggest that in addition to reducing actual waiting times, shortening perceived waiting times by improving the responses of medical staff could help to increase patient satisfaction.
