We explored associations between night eating and health outcomes in Latinos with type 2 diabetes.
Participants (n = 85) completed surveys, were measured for anthropometrics, provided blood samples, and wore Holter monitors for 24 hours to assess heart rate variability.
Participant mean age was 60.0 years, hemoglobin A1c was 8.7%, most preferred Spanish (92%), and had less than a high school education (76%). Compared with their counterparts who denied night eating, night eaters had lower heart rate variability in the low (Cohen's d = -0.55; P = 0.04) and very-low-frequency bands (d = -0.54, P = 0.05), and reported more emotional eating (d = 0.52, P = 0.04), and poorer sleep quality (Cohen's h = 0.64). They did not differ on beverage intake or depressive symptoms. In regression that included depressive symptoms, associations between night eating and outcomes became nonsignificant.
Night eaters demonstrated worse health outcomes. If results are replicated, nutrition education for this population might focus on night eating.
我们探讨了 2 型糖尿病拉丁裔人群夜间进食与健康结果之间的关联。
参与者（n=85）完成了问卷调查，进行了人体测量学测量，提供了血液样本，并佩戴了 24 小时动态心电图监测仪以评估心率变异性。
参与者的平均年龄为 60.0 岁，糖化血红蛋白为 8.7%，大多数人更喜欢西班牙语（92%），且受教育程度低于高中（76%）。与否认夜间进食的参与者相比，夜间进食者在低频（Cohen's d=-0.55；P=0.04）和极低频带（d=-0.54，P=0.05）的心率变异性更低，且报告更多的情绪化进食（d=0.52，P=0.04）和更差的睡眠质量（Cohen's h=0.64）。他们在饮料摄入量或抑郁症状方面没有差异。在包括抑郁症状的回归分析中，夜间进食与结果之间的关联变得不显著。
夜间进食者表现出更差的健康结果。如果结果得到复制，针对该人群的营养教育可能会集中在夜间进食上。
