Verification of Correlation Between Genetic Testing of Nutritional Metabolism and Clinical Biochemical Indicators

The research plan is divided into two parts. The first part is the correlation study .It is planned to include women who prepare for pregnancy or in the early stages of pregnancy to carry out the detection of 25 loci SNP of 21 genes of 9 nutrients, to predict the nutritional abnormalities of 9 nutrients, and to determine the nutritional status of 9 nutrients, and then verify the correlation between nutrient metabolism related gene SNP and nutrient nutrition status .The second part selects iron and selenium which are commonly lacking in Chinese women of childbearing age. A intervention study is designed for these two nutrients. According to the SNP grouping of related gene loci, observe the effect of nutrition intervention and explore the nutrition intervention strategies of different SNP individuals.
