Abstract. Objective: The aim of the present study is to perform a systemic review of the previous studies executed on the association between obesity and folate. Method: In the present research, the selected keywords were scanned on the PubMed, Web of Science, Cochrane and Lilac databases between May and June, 2017 through Gazi University’s network. In total, 4236 clinical, randomized controlled, cross-sectional and prospective studies were determined and 17 of these that specifically fit the aims of the present research were reviewed. This study involved an electronic literature search of databases on folic acid and obesity published in the English language between 2000 and 2016. Results: Of the 17 studies, 5 were based on folic acid supplementation and 12 were related with participants’ folate status. As a general consequence of both intake and serum/status measurements of folic acid supplementation: It was found that obesity-associated metabolic changes might affect individual folate use and obese individuals had lower serum folate levels, although there was no change in folate intake. Conclusion: Overweight and obese individuals have lower serum folate concentrations when compared with individuals with normal weight. It is explained by increased use of folic acid, urinary excretion, dilution of blood volume, different levels in different tissues and changes in the endocrine functions of folate. Individuals with higher Body Mass Indexes have less supplement use, unhealthier diets and donot consume sufficient vegetables and fruits, all of which can affect decrease in folate levels. Furthermore, adiposity may affect folate absorption by intestinal epithelium.

AbstractObjectiveTo examine the association between BMI and folate concentrations in serum and red blood cells (RBC) in pregnant women.DesignA cross-sectional comparison of folate concentrations in serum and RBC sampled simultaneously from the same individual.SettingThe Ottawa Hospital and Kingston General Hospital, Ontario, Canada.SubjectsPregnant women recruited between 12 and 20 weeks of gestation.ResultsA total of 869 pregnant women recruited from April 2008 to April 2009 were included in the final analysis. Serum folate was inversely associated and RBC folate positively associated with BMI, after adjusting for folic acid supplementation, age, gestational age at blood sample collection, race, maternal education, annual income, smoking and MTHFR 677C→T genotype. In stratified analyses, this differential association was significant in women with the MTHFR CC variant. In women with the CT and TT variants, the differential associations were in the same direction but not significant. Folic acid supplementation during pregnancy did not alter the differential association of BMI with serum and RBC folate concentration. This indicates that the current RBC folate cut-off approach for assessing risk of neural tube defects in obese women may be limited.ConclusionsBMI is inversely associated with serum folate and positively associated with RBC folate in pregnant women, especially for those with the MTHFR CC variant.

Psoriasis Severity

Background: Folic acid fortification program has been established to prevent tube defects. However, concern has been raised among patients using anti-folate drug, i.e. psoriatic patients, a common, chronic, autoimmune inflammatory skin disease associated with obesity and smoking. Objective: To investigate dietary and circulating folate, vitamin B12 (B12) and homocysteine (hcy) in psoriatic subjects exposed to the national mandatory folic acid fortification program. Methods: Cross-sectional study using the Food Frequency Questionnaire, plasma folate, B12, hcy and psoriasis severity using the Psoriasis Area and Severity Index score. Median, interquartile ranges (IQRs) and linear regression models were conducted to investigate factors associated with plasma folate, B12 and hcy. Results: 82 (73%) mild psoriasis, 18 (16%) moderate and 12 (11%) severe psoriasis. 58% female, 61% non-white, 31% former smokers, and 20% current smokers. Median (IQRs) were 51 (40, 60) years. Only 32% reached the Estimated Average Requirement of folate intake. Folate and B12 deficiencies were observed in 9% and 6% of the blood sample respectively, but hyperhomocysteinaemia in 21%. Severity of psoriasis was negatively correlated with folate and B12 concentrations. In a multiple linear regression model, folate intake contributed positively to 14% of serum folate, and negative predictors were psoriasis severity, smoking habits and saturated fatty acid explaining 29% of circulating folate. Conclusion: Only one third reached dietary intake of folate, but deficiencies of folate and B12 were low. Psoriasis severity was negatively correlated with circulating folate and B12. Stopping smoking and a folate rich diet may be important targets for managing psoriasis.

AbstractObjectiveFolic acid food fortification has successfully reduced neural tube defect-affected pregnancies across Canada. The effect of this uncontrolled public health intervention on folate intake among Canadian children is, however, unknown. Our objectives were to determine folic acid intake from food fortification and whether fortification promoted adequate folate intakes, and to describe folic acid-fortified food usage among Ontario preschoolers.DesignCross-sectional data were used from the NutriSTEP™ validation project with preschoolers recruited using convenience sampling. Mean daily total folate and folic acid intakes were estimated from 3 d food records, which included multivitamin supplement use. Comparisons were made to Dietary Reference Intakes, accounting for and excluding fortificant folic acid, to determine the prevalence of inadequate and excessive intakes.SettingCanada.SubjectsTwo hundred and fifty-four preschoolers (aged 3–5 years).ResultsAll participants (130 girls, 124 boys) ate folic acid-fortified foods and 30 % (n76) used folic acid-containing supplements. Mean (se) fortificant folic acid intake was 83 (2) μg/d, which contributed 30 % and 50 % to total folate intake for supplement users and non-users, respectively. The prevalence of total folate intakes below the Estimated Average Requirement was <1 %; however, excluding fortificant folic acid, the prevalence was 32 %, 54 % and 47 % for 3-, 4- and 5-year-olds, respectively. The overall prevalence of folic acid (fortificant and supplemental) intakes above the Tolerable Upper Intake Level was 2 % (7 % among supplement users).ConclusionsFolic acid food fortification promotes dietary folate adequacy and did not appear to result in excessive folic acid intake unless folic acid-containing supplements were consumed.

<p>Iron and folic acid supplementation is the key approach for anemia prevention and control during pregnancy. In Ethiopia only &lt;1% of pregnant mothers ingest the ideal number of tablets. Although, adherence is the most important challenge, literature is dearth and the predictors are undoubtedly recognized. Institution based quantitative cross sectional study design triangulated with qualitative methods was employed among 395 systematically selected pregnant mothers attending antenatal care in Debre Markos town, Ethiopia. Data were collected using interviewer administered structured questionnaire. Data were entered into Epi data and exported to SPSS software. Bivariate and multivariable Logistic regression with the 95% confidence interval was computed. P-value &lt; 0.05 was declared as statistically significant. Eight in-depth interviews were conducted. The data were entered and analyzed using open code software. Adherence rate was 55.5% (95%CI, 50.5%-60.4%). Pregnant mothers who had; history of anemia during current pregnancy [AOR:7.9, 95%CI (4.44-14.01)], primary education (AOR:4.0, 95%CI (1.88-8.54)], secondary education and above (AOR:3.6, 95%CI (1.20-6.94)], good knowledge of iron and folic acid supplementation [AOR:2.1, 95%CI (1.24-3.56)], and early registration for antenatal care (AOR:1.8, 95%CI (1.06-3.11)] were predictors of iron and folic acid supplementation adherence. The rate of adherence was low. Getting medical advice and fear of illness if missed were the primary reasons that enforce mothers to take the tablets. Hence, improving mothers’ knowledge regarding overall aspects of the tablet through better advice, community teaching and the mass media at large, would improve adherence.</p>

Raised total homocysteine (tHcy) levels may be involved in the etiology of cardiovascular disease and can lead to damage of vascular endothelial cells and arterial wall matrix. Folic acid supplementation can help negate these detrimental effects by reducing tHcy. Recent evidence has suggested an additional anti-atherogenic property of folate in protecting lipoproteins against oxidation. This study utilized both an in vitro and in vivo approach. In vitro: Very-low-density lipoprotein (VLDL) and low density lipoprotein (LDL) were isolated by rapid ultracentrifugation and then oxidized in the presence of increasing concentrations (0→ μmol/L) of either folic acid or 5-methyltetrahydrofolate (5-MTHF). In vivo: Twelve female subjects were supplemented with folic acid (1 mg/day), and the pre- and post-VLDL and LDL isolates subjected to oxidation. In vitro: 5-MTHF, but not folic acid, significantly increased the resistance of VLDL and LDL to oxidation. In vivo: Following folic acid supplementation, tHcy decreased, serum folate increased, and both VLDL and LDL displayed a significant increase in their resistance to oxidation. These results indicated that in vitro, only the active form of folate, 5-MTHF, had antioxidant properties. In vivo results demonstrated that folic acid supplementation reduced tHcy and protected both VLDL and LDL against oxidation. These findings provide further support for the use of folic acid supplements to aid in the prevention of atherosclerosis.

Atherosclerotic Lesions

Atherosclerosis is a chronic disease that can seriously endanger human life. Folic acid supplementation modulates several disorders, including atherosclerosis, via its antiapoptotic and antioxidative properties. This study investigated whether folic acid alleviates atherogenesis by restoring homocysteine levels and antioxidative capacity in atherosclerosis Wistar rats. To this end, 28 Wistar rats were randomly divided into 4 groups (7 rats/group) as follows: (i) wild-type group, fed only the AIN-93 semi-purified rodent diet (folic acid: 2.1 mg/kg); (ii) high-fat + folic acid-deficient group (HF+DEF) (folic acid: 0.2 mg/kg); (iii) high-fat + normal folic acid group (folic acid: 2.1 mg/kg); and (iv) high-fat + folic acid-supplemented group (folic acid: 4.2 mg/kg). After 12 weeks, histopathological changes in the atherosclerotic lesions of the aortic arch were determined. In addition, serum folate levels, plasma homocysteine levels, plasma S-adenosyl-homocysteine levels, antioxidant status, oxidant status, and lipid profiles were evaluated. The results show aggravated atherosclerotic lesions in the HF+DEF group. Folic acid supplementation increased concentrations of serum folate. Further, folic acid supplementation increased high-density lipoprotein-cholesterol, decreased plasma homocysteine levels, and improved antioxidant capacity in atherogenic rats. These findings are consistent with the hypothesis that folic acid alleviates atherogenesis by reducing plasma homocysteine levels and improving antioxidant capacity in rats fed a high-fat diet.

AbstractObjective:To investigate the hypothesis that folic acid supplementation and dietary folate intake before conception and during pregnancy reduce the risk of small for gestational age (SGA) and to examine the joint effect of folic acid supplementation and dietary folate intake on the risk of SGA.Design:Participants were interviewed by trained study interviewers using a standardized and structured questionnaire. Information on birth outcomes and maternal complications was abstracted from medical records and dietary information was collected via a semi-quantitative FFQ before conception and during pregnancy.Setting:A birth cohort data analysis using the 2010–2012 Gansu Provincial Maternity and Child Care Hospital.Participants:Women (n 8758) and their children enrolled in the study.Results:Folic acid supplementation was associated with a reduced risk of SGA (OR = 0·72, 95 % CI 0·60, 0·86), with the reduced risk seen mainly for SGA at ≥37 weeks of gestational age (OR = 0·70, 95 % CI 0·58, 0·85) and nulliparous SGA (OR = 0·67, 95 % CI 0·54, 0·84). There was no significant association between dietary folate intake and SGA risk.Conclusions:Our study suggested that folic acid supplementation was associated with a reduced risk of SGA and the risk varied by preterm status and parity.
