The Sense of Small and Inhibition in Obesity

Recruiting

• Conditions: Obesity
• Interventions: Behavioral: Experimental Task

• Registration Number: NCT05768672
• Lead Sponsor: Istituto Auxologico Italiano

Brief Summary

The aim of this research is to verify whether inhibitory control ability is different between a group of individuals with obesity and a group of individuals with normal weight in the presence of olfactory stimuli, different for valence, edibility (food versus no-food), and caloric density (high-calorie vs low-calorie content) of foods associated with odours.

Arm && Interventions

Group	Intervention	Description
Cases	Experimental Task	Right-handed Individuals diagnosed with obesity will be recruited at the beginning of a rehabilitative treatment at the Istituto Auxologico Italiano, IRCCS, San Giuseppe Hospital (Italy).
Controls	Experimental Task	Age-matched, right-handed, individuals with a healthy weight recruited outside the hospital through personal contacts of the researchers and word-of-mouth

Primary Outcome Measures

Name	Time	Method
Error %	baseline	Percentage of the invalid answers, meaning when the participant erroneously press the key (i.e., answer) in the no-go (invalid) trials. This represents an index of inhibitory difficulty in the experimental task. This score will be computed according to Albayay and colleagues (2019).

Secondary Outcome Measures

Name	Time	Method
Interference Error	baseline	It will computed according to the following formula: score = CW - ((W + C)/2). The lower is the score, the best is the performance. Notably for each condition (W, C, and CW) the number of error can range from O (no error) to 36 (maximun number of error). This computation derives from the seminal article for the Italian version of the test (Caffarra et al., 2004).
