Nutricity: A Pilot Study to Improve Parental Nutrition Literacy

Nutricity website: Nutricity is a mobile website that uses communication techniques that
break down each section to teach parents and children the nutrition information. The site
addresses five components of nutrition literacy:

1. ability to comprehend nutrition text

2. eating foods in the right portions

3. using food labels to make nutrition decisions

4. grouping foods into like categories

5. choosing between similar foods (consumer skills)

Participants will have three months of free access to Nutricity during this study. They will
also be encouraged to set one nutrition goal per week and encouraged to use Nutricity to help
attain that goal. Participants will send weekly goals through text message to a number
provided by the research team.

There are three phases to this study:

Baseline: Participants will be asked to come to the clinic or research lab 1 time for
procedures and assessments that will help the investigator assess nutrition literacy and
eligibility.

Nutricity: During this phase participants will use their smartphone to access the Nutricity
website to potentially increase nutrition literacy and set nutrition goals.

This phase will last approximately 3 months.

End Study: Participants will be asked to come to the research lab 1 time to perform the same
procedures and assessments completed in the baseline visit.

Assessments include:

Height/Weight: Parent/guardian and child will have their height and weight measured.

Demographics: questionnaires will ask for information such as name, date of birth and race.

Nutrition Questionnaires: Participants will complete 1 questionnaire on 2 occasions to assess
nutrition literacy using the Nutrition Literacy Assessment Instrument (NLit). The NLit
measures nutrition literacy and is comprised of six domains:

1. nutrition and health

2. energy sources in food

3. household food measurement

4. food labels/numbers

5. food groups

6. consumer skills

Parents/Guardians will also be asked about fruit, vegetable, fat, and fiber intake.

24-hour Recall: Parents will be asked questions about a child's current diet over the
previous 24 hours. For children who eat meals at school or daycare, researchers will provide
forms to the child's teacher or daycare provider to record the meals they eat while there.
Two additional recalls will be done during the study that will be done with researchers over
the phone.

Resonance Raman Spectroscopy (Veggie Meter): During this assessment, the veggie meter will
apply gentle pressure to the pad of a child's fingertip to put it in close contact with
light, to detect and measure carotenoid in the blood. Carotenoids are the yellow, orange, and
red colors that are produced in plants, such as tomatoes. Three, 10-45 second measurements
are taken and averaged for the recorded score.

Exit Survey: Upon completion of the study, participants will complete one questionnaire to
provide the researchers feedback on their experience in the study.

Inclusion Criteria:

- Parents must be English speaking and must 1) Identify as primary food decision-maker
for the home, 2) Have internet access at home and 3) Must have a device for accessing
the internet. Smartphones, owned by ~75-92% of the target population, are adequate to
satisfy the latter two criteria.

Exclusion Criteria:

- 1) Overt cognitive or psychiatric illness, 2) Visual impairments that preclude reading
survey instruments or using a tablet, 3) Child illness requiring a highly restrictive
diet, such as renal disease, celiac disease, etc., 4) Planning to travel
internationally during the study, 5) child is a foster child or ward of the state.
