Night eating syndrome (NES) is associated with adverse health outcomes. This study evaluated the relationship between night eating severity, weight, and health behaviors.
Participants (N = 1017; 77.6% female, mean Body Mass Index (BMI) = 30.5, SD = 7.8 kg/m, age = 51.1, SD = 15.0 years) were recruited from three health systems. Participants completed the Night Eating Questionnaire (NEQ) and questionnaires assessing sleep, chronotype, physical activity, diet, weight, and napping.
In the overall sample, higher NEQ scores were associated with higher BMI (p < .001) and consumption of sugar-sweetened beverages (p < .001), as well as lower fruit/vegetable consumption (p = .001). Higher NEQ scores were associated with increased odds of having overweight/obesity (p < .001), eating fast food (p < .001), moderate-vigorous physical activity (p = .005), and smoking (p = .004). Participants who exceeded the screening threshold for NES (n = 48, 4.7%) reported elevated BMI (p = .014), an increased likelihood of overweight/obesity (p = .004), greater sugar-sweetened beverages consumption (p < .001), napping less than twice per week (p = .029), shorter sleep duration (p = .012), and a later chronotype (M = 4:55, SD = 2:45).
Night eating severity was associated with obesity and intake of fast food and sugar-sweetened beverages. Interventions to address night eating and associated behaviors may enhance the efficacy of weight management interventions and promote engagement in positive health behaviors.
夜间进食综合征（NES）与不良健康结果有关。本研究评估了夜间进食严重程度、体重和健康行为之间的关系。
参与者（N=1017；77.6%为女性，平均体重指数（BMI）=30.5，标准差（SD）=7.8kg/m，年龄=51.1，SD=15.0 岁）从三个健康系统招募。参与者完成了夜间进食问卷（NEQ）和评估睡眠、昼夜节律、身体活动、饮食、体重和小睡的问卷。
在整个样本中，NEQ 得分较高与 BMI 较高（p<0.001）和糖饮料消费较高（p<0.001）有关，与水果/蔬菜消费较低有关（p=0.001）。NEQ 得分较高与超重/肥胖的几率增加（p<0.001）、食用快餐（p<0.001）、中高强度体力活动（p=0.005）和吸烟（p=0.004）有关。超过 NES 筛查阈值的参与者（n=48，4.7%）报告 BMI 升高（p=0.014）、超重/肥胖的可能性增加（p=0.004）、糖饮料消费增加（p<0.001）、每周小睡次数少于两次（p=0.029）、睡眠持续时间缩短（p=0.012）和昼夜节律较晚（M=4:55，SD=2:45）。
夜间进食严重程度与肥胖以及快餐和含糖饮料的摄入有关。针对夜间进食和相关行为的干预措施可能会提高体重管理干预的效果，并促进积极健康行为的参与。
