Analysis of the Total Food Folate Intake Data from the National Health and Nutrition Exa-amination Survey (Nhanes) Using Generalized Linear Model

چکیده
The National health and nutrition examination survey (NHANES) is a respected nation-wide program in charge of assessing the health and nutritional status of adults and children in United States. Recent cal research found that folic acid play an important role in preventing baby birth defects. In this paper, we use the generalized estimating equation (GEE) method to study the generalized linear model (GLM) with compound symmetric correlation matrix for the NHANES data and investigate significant factors to ence the intake of food folic acid.

متن کاملContributions of total daily intake of folic acid to serum folate concentrations.
To the Editor: Recent literature has associated potential adverse effects with daily use of folic acid supplements (1000 μg), high concentrations of serum folate (26.5 ng/mL or greater [to convert to nmol/L, multiply by 2.266]), or high folic acid intake, but researchers have not adequately considered the source of folic acid. We examined the relative contribution of different sources of folic ...

DESIGN Cross-sectional, observational study. SETTING What W...
متن کاملReassessing folic acid consumption patterns in the United States (1999 2004): potential effect on neural tube defects and overexposure to folate.
BACKGROUND In the United States, folic acid fortification of cereal- grain foods has significantly increased folate status. However, blood folate concentrations have decreased from their postfortification high as a result, in part, of decreasing food fortification concentrations and the popularity of low-carbohydrate weight-loss diets. OBJECTIVES The objectives of the study were to quantify c...

The objective of this study was to assess agreement on nutrient intake between the nutrient database of the First National Health and Nutrition Examination Survey (NHANES I) and an up-to-date (December 1998) nutrient database, the ESHA Food Processor. Analysis was conducted among 11,303 NHANES I participants aged 25-74 years in 1971-1975 who had undergone dietary assessment. A list of all uniqu...
