what are the two national surveys used to assess intake, body weight, and nutrition related outcomes
- national health and nutrition examination surveys (NHANES)
- behavioral risk factor surveillance system (BRFSS)
national health and nutrition examination surveys NHANES
-conducted in person
behavioral risk factor surveillance survey BRFSS
conducted by phone
- some data is validated but there may be some self report bias to consider since it is not in person
- not as reliable as the NHANES
what are the two national systems for dietary guidance
- dietary reference intake
- dietary guidelines for americans
dietary reference intake
- provide recommendations for intake of specific nutrients and water
- shown as either the recommended dietary allowance RDA or the adequate intake AI
RDA vs AI
- RDA represents stronger scientific evidence than does AI
- RDA is the amount that has been estimated to maintain sufficiency in 97-98% of the population
dietary guidelines for americans
-advice to promote health, prevent disease, and serves as the basis for federal food assistance programs such as assistance to women, infants, and children (WIC)
