Dietary and lifestyle predictors of folate insufficiency in non-supplemented German women
2019
AbstractLow folate status is a risk factor for birth defects. We studied concentrations of red blood cell (RBC)- and serum folate in 198 German women in relation to information on dietary folate intake, demographic and lifestyle factors. Median serum- and RBC-folate levels were; (14.7 and 589 nmol/L, respectively. Serum 952 nmol/L (optimal levels around conception) were observed in 9.6%. Serum- and RBC-folate were positively associated; they showed the expected correlations with homocysteine, but only weak correlations with folate intake. Younger age, lower fibre and higher carbohydrate intakes were associated with lower blood folate. Thus, folate intake of approximately 278 µg/d was not sufficient to achieve optimal folate status in young women. In conclusion, in the absence of fortification with folic acid, the majorit...
