Association of Colecalciferol, Ferritin, and Anemia among Pregnant Women: Result from Cohort Study on Vitamin D Status and Its Impact during Pregnancy and Childhood in Indonesia

الملخص EN

Studies had shown that iron-cycling was disturbed by inflammatory process through the role of hepcidin.

Pregnancy is characterized by shifts of interleukin.

Our objective was to determine if 25(OH) vitamin D (colecalciferol) status was associated with ferritin, anemia, and its changes during pregnancy.

Method.

A cohort study was done in 4 cities in West Java, Indonesia, beginning in July 2016.

Subjects were followed up until third trimester.

Examinations included were maternal ferritin, colecalciferol, and haemoglobin level.

Result.

191 (95.5%) subjects had low colecalciferol, and 151 (75.5%) among them were at deficient state.

Anemia is found in 15 (7.5%) subjects, much lower than previous report.

Proportion of anemia increased by trimester among women with colecalciferol deficiency.

Ferritin status and prepregnancy body mass index in the first trimester were correlated with anemia (r=0.147, p=0.038 and r=-0.56, p=0.03).

Anemia in the second trimester was strongly correlated with anemia in the third trimester (r=0.676, p<0.01).

Conclusion.

Our study showed that the state of colecalciferol was not associated with either ferritin state or anemia, but proportion of anemia tends to increase by trimester in the colecalciferol deficient subjects.
