A systematic review and meta-analysis of attentional bias toward food in individuals with overweight and obesity. Appetite. 2020 Apr 13;:104710 Authors: Hagan KE, Alasmar A, Exum A, Chinn B, Forbush KT Abstract Attentional bias to food stimuli may contribute to the etiology and/or maintenance of overweight and obesity. We conducted a literature review and meta-analysis per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify the effect size associated with attentional bias to palatable food in persons with overweight/obesity across the age spectrum. Included studies measured attentional bias to food stimuli using two reaction-time tasks (dot-probe, emotional Stroop), eye-tracking methodology, and/or event-related potentials. Meta-analysis showed that persons with overweight/obesity did not differ from persons with a healthy weight on any of the following: automatic and maintained attention to food stimuli measured by the dot-probe task (Hedge's gautomatic = -0.355, 95% CI = -0.383, 0.486; and Hedge's gmaintained = 0.006, 95% CI = -0.187, 0.199); attentional bias to food stimuli measured by the emotional Stroop task (Hedge's g = 0.184, 95% CI = -0.283, 0.651); and attentional bias to food images on gaze-direction and gaze-duration bias eye-tracking metrics (Hedge's gdirection = 0.317, 95% CI = -0.096, 0.729; and Hedge's gduration = 0.056, 95% CI =â...
