- W336151889 abstract "Information on folate and vitamin B12 deficiency rates in Guatemala is essential to evaluate the current fortification program. The objectives of this study were to describe the prevalence of folate and vitamin B12 deficiencies among women of childbearing age (WCBA) in Guatemala and to identify vulnerable populations at greater risk for nutrient deficiency.A multistage cluster probability study was designed with national and regional representation of nonpregnant WCBA (15-49 years of age). Primary data collection was carried out in 2009-2010. Demographic and health information was collected through face-to-face interviews. Blood samples were collected from 1473 WCBA for serum and red blood cell (RBC) folate and serum vitamin B12. Biochemical concentrations were normalized using geometric means. Prevalence rate ratios were estimated to assess relative differences among different socioeconomic and cultural groups including ethnicity, age, education level, wealth index and rural versus urban locality.National prevalence estimates for deficient serum [<10 nmol per liter (nmol/L)] and RBC folate (<340 nmol/L) concentrations were 5.1 % (95 % CI 3.8, 6.4) and 8.9 % (95 % CI 6.7, 11.7), respectively; for vitamin B12 deficiency (<148 pmol/L) 18.5 % (95 % CI 15.6, 21.3). Serum and RBC folate deficiency prevalences were higher for rural areas than for urban areas (8.0 vs. 2.0 % and 13.5 vs. 3.9 %, respectively). The prevalence of RBC folate deficiency showed wide variation by geographic region (3.2-24.9 %) and by wealth index (4.1-15.1 %). The prevalence of vitamin B12 deficiency also varied among regions (12.3-26.1 %).In Guatemala, folate deficiency was more prevalent among indigenous rural and urban poor populations. Vitamin B12 deficiency was widespread among WCBA. Our results suggest the ongoing need to monitor existing fortification programs, in particular regarding its reach to vulnerable populations." @default.
