BACKGROUND
An extensive body of recent research has focused on the contribution of cognitive functioning to eating behaviors. In binge eating disorder (BED) and food addiction (FA), the extent of cognitive impairment is still unclear. This study aimed to characterize, among those with BED and FA, neurocognitive functions using performances based on neuropsychological tasks in the context of neutral stimuli in adults.
METHOD
MEDLINE, Embase, PsycINFO, Cochrane Database of Systematic Reviews, CINAHL and gray literature (ProQuest and OpenGrey) were used to identify studies that reported neurocognitive assessments in BED or FA up to December 2019. A three-level meta-analysis was conducted.
RESULTS
A significant overall effect was found for global cognitive impairments, suggesting that individuals with BED or FA have poorer performances when completing cognitive tasks. Analyses for specific cognitive domains revealed that individuals with BED showed poorer performances at tasks assessing cognitive flexibility, inhibitory control, attention and planning. Analyses regarding FA were inconclusive due to a lack of studies. Thus, the results were described qualitatively.
CONCLUSION
Our meta-analysis highlighted the cognitive weaknesses that seem to come with BED and the necessity to integrate them in the assessment and treatment of this condition. It also stressed the lack of quality studies surrounding the cognitive features of FA.
背景
近期大量研究集中于认知功能对进食行为的影响。在暴食障碍（BED）和食物成瘾（FA）中，认知损伤的程度仍不明确。本研究旨在通过对成人中性刺激情境下神经心理任务的表现，描述 BED 和 FA 患者的神经认知功能。
方法
本研究检索了 MEDLINE、Embase、PsycINFO、Cochrane 系统评价数据库、CINAHL 和灰色文献（ProQuest 和 OpenGrey），以确定截至 2019 年 12 月报告 BED 或 FA 患者神经认知评估的研究。采用三级元分析。
结果
发现整体认知障碍存在显著的总体效应，这表明 BED 或 FA 患者在完成认知任务时表现较差。对特定认知领域的分析表明，BED 患者在评估认知灵活性、抑制控制、注意力和计划的任务中表现较差。由于缺乏研究，FA 的分析结果没有定论。因此，结果以定性方式描述。
结论
本元分析强调了 BED 患者存在的认知缺陷，需要将其纳入该疾病的评估和治疗中。此外，还强调了 FA 的认知特征方面缺乏高质量研究。
