Spørgeskemaer til madhyppighed til estimering af fødeindtag af næringsstoffer hos raske unge voksne

Komparativ vurdering af spørgeskemaer til fødevarehyppighed

Fruits and vegetables are an important source of many different phytochemicals that may affect health and accurate dietary assessement tools to quantitate dietary intake are essential. This study will evaluate the correlation of dietary carotenoid intake estimated from two common and one novel food frequency questionnaire (FFQ) with estimated carotenoid intake from 3 day diet records as well as measured blood and skin concentrations of carotenoids. This study will be conducted in healthy adults. These tools may be effective in estimating the level of these compounds in an average diet.

Detaljeret beskrivelse

PRIMARY OBJECTIVES:

I. To examine the relationship between estimated intakes of dietary carotenoids using three different FFQ's and comparing them with estimated carotenoid intake from 3 day diet records and blood and skin measurements.

OUTLINE:

Participants complete the Willett FFQ, the Fred Hutchinson FFQ, and the newly developed Clinton Carotenoid Assessment Tool (CCAT), in random order over a 3 to 4-month period of time with 4-6 weeks between each visit. Prior to each visit, participants also complete a 3-day diet record, a daily sun exposure diary, and a 3-day activity record. Blood samples are collected for plasma carotenoid assessment and and skin carotenoid content is assessed using a resonance Raman spectroscopy.

Intervention / Behandling
Observational (Willett FFQ, Fred Hutchinson FFQ, CCAT)

After consenting to participate in this study, participants will visit the Clinical Research Center (CRC) on 3 occasions. One of the three FFQ's will be completed at each visit and there will be 4 to 6 weeks between visits. Participants will also complete a blood draw and assessment of skin carotenoids at this CRC visit. Prior to each visit, participants will complete a 3-day diet record, a daily sun exposure diary, and a 3-day activity record.

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
FFQ estimated carotenoid intake
Tidsramme: Up to 3 months

The relationship between the carotenoid values from the FFQ, both the unadjusted and the energy-adjusted estimates, and averages of the 3-day diet records will be estimated using the Pearson correlation coefficients. Statistical analysis will be conducted using Stata version 11.

Up to 3 months
Levels of carotenoids in plasma
Tidsramme: Up to 3 months

Pearson correlations will be used to compare plasma levels of individual carotenoids with their respective dietary intake after adjustment for total energy, plasma cholesterol, plasma triglycerides, and BMI. Statistical analysis will be conducted using Stata version 11.

Up to 3 months
CCAT ability to estimate carotenoid intake
Tidsramme: Up to 3 months

CCAT carotenoid intake will be correlated with blood carotenoid profiles. Statistical analysis will be conducted using Stata version 11.

Up to 3 months
