Quantitative Evaluation of Bitter Taste in Obesity

Completed

• Conditions: Obesity

• Registration Number: NCT03149666
• Lead Sponsor: University of Sao Paulo

Brief Summary

Although taste influences food choices and favours diseases like obesity, there is no consensus about the existence of correlations between bitterness and anthropometric variables. Also, an electronic-based method for data collection could provide a more appropriate way for the evaluation of taste perception and save time.

The objective is to search for correlations between bitterness and anthropometric variables.

Detailed Description

A cross-sectional study evaluating correlations between the bitterness rates given on a generalized Labeled Magnitude Scale, anthropometrics and other variables. Bitterness perceptions at the tip of the tongue (TOTp) and at the whole mouth (WMp) were recorded using a locally developed novel cloud-based software (Cloud-gLMS). The ANCOVA test was adjusted using TOTp and WMp as dependent variables and age, height, weight, BMI, gender, waist circumference, alcohol intake, comorbidities, and use of medications as independent variables.

Primary Outcome Measures

Name	Time	Method
Sensitivity of bitter taste 2	1 time	The volunteer will perform a "mouthwash" with the quinine solution, and will point a note to the bitter level.
Sensitivity of bitter taste 1	1 time	It will be gently applied at the end of the tongue, by means of a swab soaked in the quinine solution at room temperature, in continuous movements from left to right, and will point a note to the bitter level.
