Background:
Inter-generational dietary patterns are implicated in the development of adult disease and have a critical role in cell division, growth and development.
Objective:
The assessment of B(12) status in six meat-eating (ME) and six non-meat-eating (NME) 9-11 years old, Tanner stage 1, migrant Indian girls.
Design:
B(12) status was assessed by haematology, fasting B(12), folate, methyl malonic acid (MMA) and 7-day-diet-diary analysis.
Results:
Red cell and iron measurements were within reference ranges for all girls. Reported B(12) intake correlated with serum B(12) (r=0.74, P=0.006). Serum B(12) was lower in NME girls compared with ME girls (232+/-95 vs 543+/-201 pmol l(-1), P=0.01). Two NME girls were deficient in vitamin B(12) (B(12)<170 pmol l(-1), MMA>0.26 micromol l(-1)). Overall serum B(12) was low (388+/-221 pmol l(-1)) and serum folate intake high (27+/-8 pmol l(-1); 342+/-269 microg day(-1)).
Conclusions:
Asymptomatic B(12) deficiency is present in NME migrant Indian preadolescents in the presence of high folate. Supplementation with B(12) in this group may be necessary to improve future health outcomes.

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...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
