The goal of the study is to determine whether there are age-, diet- and genetically-related differences in the perception of sweeteners, both nutritive and non-nutritive.
This is an observational 3-day study of children between the ages of 7 and 14 and their mothers. A variety of psychophysical methods determined liking for each of the sweeteners and saliva samples were obtained for genotyping of taste receptor genes. Anthropometric and dietary intake measures were also collected.
Study Type
OBSERVATIONAL
Enrollment
82
Participants tasted a variety of nutritive and nonnutritive sweeteners
Liking for the taste of sweeteners measured via the 3-point facial hedonic scale.
Time frame: Through study completion, an average of 6 months.
Liking for the taste of sweeteners measured via the 5-point facial hedonic scale
Time frame: Through study completion, an average of 6 months.
Liking for the taste of sweeteners measured via the Monell forced-choice, paired-comparison tracking procedure.
Time frame: Through study completion, an average of 6 months.
Genotyping of taste receptor genes via saliva donation
Genotyping will be completed to measure associations between individual taste receptor genotypes and liking of sweeteners.
Time frame: Through study completion, an average of 6 months
BMI calculated from body weight and height measures
BMI will be calculated to examine associations between this measure and liking for sweeteners.
Time frame: Through study completion, an average of 6 months
One day dietary intake collected via the Automated Self-Administered 24-hour dietary recall (ASA24).
Dietary recall will be completed to examine associations between added sugar intake and liking for sweeteners.
Time frame: Through study completion, an average of 6 months
