The tendencies to overeat in response to negative emotions (emotional eating) and environmental cues (external eating) have both been associated with BMI. However, it is unclear how they are expressed at the eating architecture level, for example, respecting frequency, timing and size of eating occasions, which could comprise 'downstream' specific behavioural intervention targets. In our analyses of the UK National Diet and Nutrition Survey 2000-2001, a 1-unit higher emotional eating score was associated with meals containing approximately 15 (3, 26) fewer kcals per occasion, consuming 1.4 (0.5, 2.3) more snacks per week and snacking over a 35- (16, 53) minute longer period a day. A 1-unit higher external eating score was associated with snacking over a 24- (1, 46) minute shorter period a day. Associations were independent of BMI and other potential confounders. The distinct pattern of eating architecture associated with emotional eating, suggests specific approaches to intervention, such as the number, timing and caloric content of snacks, could be considered further in experimental studies for their potential to prevent weight gain in people with a higher emotional eating tendency. Longitudinal studies and better measurement are also needed to strengthen causal inference in terms of the downstream effects of eating styles.
人们在应对负面情绪(情绪性进食)和环境线索(外食)时往往会过度进食,这两者都与 BMI 有关。然而,目前尚不清楚它们在进食结构层面上是如何表现的,例如,尊重进食的频率、时间和食量,这些可能是“下游”特定行为干预的目标。在对英国 2000-2001 年全国饮食与营养调查的分析中,情绪性进食评分每增加 1 个单位,每餐的热量就会减少约 15(3,26)卡路里,每周多吃 1.4(0.5,2.3)份零食,每天的零食时间延长 35(16,53)分钟。外食评分每增加 1 个单位,每天的零食时间就会减少 24(1,46)分钟。这些关联与 BMI 及其他潜在混杂因素无关。与情绪性进食相关的进食结构的独特模式表明,干预措施可能会考虑特定的方法,如零食的数量、时间和热量含量,这在实验研究中可能会被进一步考虑,以防止情绪性进食倾向较高的人群体重增加。还需要进行纵向研究和更精确的测量,以加强对饮食方式下游影响的因果推断。
