1. Patel CJ, et al. (2012). National Health and Nutrition Examination Survey (NHANES) We screened for correlation between environmental factors and lipid levels, utilizing four independent surveys with information on 188 environmental factors from the Centers of Disease Control, National Health and Nutrition Examination Survey, collected between 1999 and 2006. age | body mass index | race | sex | socioeconomic status 2,2',3,3',4,4',5-heptachlorobiphenyl | 2,3-bis(3'-hydroxybenzyl)butyrolactone | 2,4,4',5-tetrachlorobiphenyl | 2-hydroxyfluorene | alpha-Tocopherol | Ascorbic Acid | beta Carotene | Cotinine | Cryptoxanthins | Fluorenes | Folic Acid | gamma-Tocopherol | Heptachlor Epoxide | Iron | Lycopene | Mercury | nonachlor | oxychlordane | retinol palmitate | retinyl stearate | Vitamin A | Vitamin D Study subjects United States Details cholesterol metabolic process | triglyceride metabolic process
2. Zablotska LB, et al. (2008). Health Effects of Arsenic Longitudinal Study (HEALS) Intakes of B-vitamins and antioxidants, at doses greater than the current recommended daily amounts for the country, may reduce the risk of arsenic-related skin lesions in Bangladesh. age | body mass index | sex | socioeconomic status Arsenic | Ascorbic Acid | Folic Acid | Pyridoxine | Riboflavin | Vitamin A | Vitamin E Study subjects Bangladesh Details Skin Ulcer
3. Gamble MV, et al. (2005). Nutritional Influences on Arsenic Toxicity Study (NIAT) Our objectives of this cross-sectional study were to characterize the relationships among folate, cobalamin, homocysteine, and arsenic metabolism in Bangladeshi adults. Arsenic | Creatinine | Folic Acid Study subjects Bangladesh urine | water Arsenic Details methylation | response to arsenic-containing substance
4. Hall MN, et al. (2009). In summary, among this group of Bangladeshi adults with a high prevalence of cobalamin deficiency, cobalamin appeared to facilitate the methylation of inorganic arsenic to monomethylarsonic acid, particularly among women and among folate sufficient individuals. Arsenic | Creatinine | Folic Acid | Homocysteine | Vitamin B 12 Study subjects Bangladesh plasma | urine | water Arsenic | Creatinine | Folic Acid | Homocysteine | Vitamin B 12 Details
5. George CM, et al. (2013). Health Effects of Arsenic Longitudinal Study (HEALS) Our results suggest that selenium is inversely associated with biomarkers of arsenic burden in both adults and children. Arsenic | Creatinine | Folic Acid | Selenium | Vitamin B 12 Children | Study subjects Bangladesh blood | urine | water Arsenic | Creatinine | Folic Acid | Selenium | Vitamin B 12 Details
6. Hall MN, et al. (2009). Health Effects of Arsenic Longitudinal Study (HEALS) These findings suggest that, similar to adults, folate and cysteine facilitate arsenic methylation in children. However, the inverse correlation between total homocysteine and %monomethylarsonic, and positive correlation with %dimethylarsinic acids, are both opposite to our previous findings in adults. age Arsenic | Cysteine | Folic Acid Children Bangladesh plasma | urine | water Arsenic | Creatinine | Cysteine | Folic Acid | Homocysteine | Vitamin B 12 Details cellular response to chemical stimulus
7. Mazumdar M, et al. (2015). Our study found a significant interaction between drinking water inorganic arsenic concentration during the first trimester of pregnancy and reported intake of periconceptional folic acid supplements, and the results suggest that environmental arsenic exposure reduces the effectiveness of folic acid supplementation in preventing myelomeningocele, while no main effect of arsenic exposure on myelomeningocele risk was identified. diet Arsenic | Folic Acid Pregnant females Bangladesh plasma | water, well Arsenic | Folic Acid Details response to folic acid
8. Hutson JR, et al. (2012). Our results demonstrate that chronic and heavy alcohol use in pregnancy impairs folate transport to the fetus. Altered folate concentrations within the placenta and in the fetus may in part contribute to the deficits observed in the fetal alcohol spectrum disorders. alcohol drinking Ethanol Fetuses | Pregnant females Canada plasma | plasma, cord Folic Acid Details Fetal Alcohol Spectrum Disorders | transport
9. Colapinto CK, et al. (2014). Canadian Health Measures Survey (CHMS) | National Health and Nutrition Examination Survey (NHANES) In summary, the fact that we found erythrocyte folate concentrations were either higher or lower in Canadians compared with Americans, depending on whether an adjustment was made to account for assay differences, suggests that caution must be exercised in evaluating erythrocyte folate data from different countries because analytical methods are not readily comparable.
