Nighttime food intake is associated with weight gain and higher HbA1c levels. We experienced night eaters who have no memory of their nocturnal eating in the morning. In this study, the curious night eating behavior was designated as “unremembered nocturnal eating syndrome (UNES)”. We screened 1,169 patients with diabetes for sleep quality and abnormal eating behavior at night using the Pittsburgh Sleep Quality Index questionnaire with an additional question regarding UNES. When abnormal nocturnal eating behavior was noted, detailed clinical information was extracted from interviews with the patients. We identified 9 patients who experienced UNES. They had a higher BMI compared with subjects who reported no such episodes. Among them, 6 patients who consumed food at night without memory 2-5 times per month or more had significantly higher HbA1c levels. Continuous glucose monitoring in a patient with type 1 diabetes revealed an abrupt elevation of glucose levels from midnight when some foods were consumed. Eight of the 9 patients were taking benzodiazepine and/or non-benzodiazepine hypnotic agents when they experienced the episodes. The prevalence of UNES was 0.8% in all subjects and 4% in those taking hypnotic drugs. The ratio of hypnotic drug use in subjects with UNES was significantly higher than for individuals without UNES (89% vs. 17%, p<0.0001). Although UNES seems to be etiologically heterogeneous, hypnotics-induced parasomnia and/or anterograde amnesia may be associated with the behavior. UNES is not rare in diabetic patients on hypnotic medicine and may be a hidden cause of unexpected morning hyperglycemia. HubMed – eating


Do eating behaviors in the general population account for country variance in glycemic control among adolescents with diabetes: the Hvidoere Study Group and the Health Behaviour in School-Aged Children study.

BACKGROUND: The Hvidoere Study Group (HSG) has demonstrated major differences in glycemic control between pediatric diabetes centers which remain largely unexplained. This study investigates whether these differences are partly attributable to healthy eating norms in the background population. METHODS: The study involved adolescents from 18 countries from (i) the Health Behaviour in School-Aged Children study (HBSC) and (ii) the HSG. There were 94?387 participants from representative HBSC samples of 11-, 13- and 15-yr-olds and 1483 11- to 15-yr-old adolescents with diabetes from the HSG. The frequency of intake of fruit, vegetables, sweets, sugary soft drinks, and daily breakfast was compared between the two groups. The glycemic control of the adolescents in the HSG cohort was determined by measuring glycated hemoglobin (HbA1c). RESULTS: Across countries in the HSBC survey, there was substantial variation in prevalence of healthy eating behavior and even greater variation between adolescents from the HSG centers. In all countries more adolescents with diabetes reported healthy eating behavior compared to national norms. In individuals healthy eating behavior had a significant effect on the individual level HbA1c. There was no significant correlation between the frequencies of these healthy eating behaviors at (i) the national level and (ii) diabetes center level and the center mean HbA1c. CONCLUSIONS: Although individual healthy eating behavior is associated with better glycemic control at the individual level, such eating behavior does not explain the center differences in HbA1c. Similarly, the reported healthy eating norm of the background populations does not explain the variation in glycemic control among centers. HubMed – eating
