Clinical trial NCT03149666: Quantitative Evaluation of Bitter Taste in Obesity
Official title: Anthropometric Variables and Perception of Bitter Taste in Obese Adults or Not
Study type: OBSERVATIONAL
Overall status: COMPLETED
Conditions: Obesity
Lead sponsor: University of Sao Paulo
Sponsor class: OTHER
First posted: 2017-05-11
Enrollment: 262
Sex: ALL
Minimum age (years): 18
Maximum age (years): 59
Standard ages: ADULT
Accepts healthy volunteers: yes
Observational model: OTHER
Time perspective: CROSS_SECTIONAL
Sampling method: NON_PROBABILITY_SAMPLE
Study population: Healthy people without obesity and people with obesity.

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.

Eligibility criteria: Inclusion Criteria:

* Weight limit of 150 kg and who are able to read the text with the guidelines on how to be punctuated the sensation of bitter in the generalized labeled scale.

Exclusion Criteria:

* Being a relative of the first degree of a patient already included in the research, tobacco in the forms of cigarettes, pipes and cigars in the last 30 days, presence of coryza, nasal congestion or frequent sneezing, dental treatment on the same day of the research. Being a dementia sufferer, having an altered, drowsy level of consciousness. Show upper limb tremor visible.
