Sample details

The PERSIAN birth cohort is a multi-centre network of population-based birth cohorts in Iran, conducted as part of the Prospective Epidemiological Research Studies in IrAN (PERSIAN) cohort. Around 15,000 pregnant women were enrolled between 2016 and 2019 from five Iranian cities (Isfahan, Yazd, Semnan, Rafsanjan and Sari). After baseline, mothers were followed up at each trimester until birth. The children were assessed at birth, 2, 4, 6, 12, and 24 months; thereafter, they are being followed annually for up to 10 years.
