ICMR invites EoIs for data contribution for pregnancy cohort studies

IN order to understand hypothyroidism during pregnancy among Indian women, the Indian Council of Medical Research (ICMR) has invited Expression of Interests (Eols) from researchers and institutions to contribute data from ongoing or completed pregnancy cohort studies or randomized controlled trials (RCTs).

Submission timeline is December 1, 2025.

The objective is to generate high-quality evidence to provide deeper insights into hypothyroidism during pregnancy, based on current reference ranges for thyroid function.

Primary objectives of the EoI is to estimate the prevalence of hypothyroidism (overt and subclinical) among pregnant women across diverse Indian populations using current trimester-specific reference ranges, to identify risk factors associated with hypothyroidism in pregnancy, to assess the associations between subclinical hypothyroidism (SCH) and adverse pregnancy and foetal outcomes (e.g., preeclampsia, gestational hypertension, gestational diabetes, stillbirth, low birth weight, preterm birth etc.).

This would also develop normative reference values for thyroid function parameters in Indian pregnant women.
