Abstract:
The true burden of micronutrient deficiencies among women of reproductive age (WRA) in many resource-limited settings is likely underestimated, as data on several "neglected micronutrients" remain sparse. We used data from a cross-sectional survey of 100 nonpregnant WRA in the region of Oromia, Ethiopia to describe the prevalence of various micronutrient deficiencies and other indicators of nutritional status. The prevalences of anemia (hemoglobin < 13.4 g/dL, adjusted for altitude) and iron deficiency (inflammation-adjusted serum ferritin < 15 ug/L) were 7.1% and 4.0%, respectively. However, 100.0% of females were deficient in riboflavin [erythrocyte glutathione reductase activation coefficient (EGRac) > 1.4], and the prevalences of thiamine insufficiency [erythrocyte transketolase activity coefficient (ETKac) 1.15-1.25], folate insufficiency [red blood cell (RBC) folate < 748 nmol/L], and vitamin B12 insufficiency (serum B12 < 221 pmol/L) were 38.8%, 96.0%, and 52.6%, respectively. Future surveys should include a more comprehensive assessment of B vitamins to corroborate these findings and inform the design of appropriate interventions to improve status.

Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
