Background: Limited information is available on iodine deficiency among pregnant women in India. The objective of the study was to assess the iodine nutrition status and other micronutrient deficiencies among pregnant women.

Materials and methods: This study reports the baseline findings of a longitudinal study of 200 pregnant women from 28 villages of Haryana, North India. Blood and urine samples were collected for assessment of T3, T4, TSH, ferritin, B12 and urinary iodine. Samples were analysed in Centre for Promotion of Nutrition Research & Training Laboratory, New Delhi.

Results: The mean gestational age at enrolment was 8.8 (SD  2) weeks. The median UIC was 275 (range 170-425 µg/dl) and 14% household salt samples had iodine <15ppm. Low level of serum ferritin (≤ 15ng/ml) was seen in 56%, low haemoglobin (≤ 12g/dl) in73%, low B12 (≤ 203 pg/ml) in 48%, low T3 (< 81ng/dl) 7% and low T4 (4.5/dl) in 0.5%. 9% participants had elevated TSH levels (≥5 ng/dl). Pregnant women with low UIC had elevated TSH levels compared to pregnant women with normal UIC.

Conclusions: The iodine nutrition in pregnant women in first trimester in the study population was adequate. Anemia continues to be a serious public health problem.
