AZAR cohort
The AZAR cohort aims to identify environmental risk factors for common diseases by comprehensively assessing external exposures, lifestyle (including dietary patterns), social determinants, and ethnic and individual factors in disease progression. The AZAR cohort was established in Shabestar County in East Azerbaijan province, north-western Iran. The study has been set up in three phases: (i) pilot study; (ii) enrolment of participants; and (iii) regular follow-up of subjects for 15 years. The participants are permanent residences of Shabestar district, who have at least one Azeri parent, and were aged between 35 and 70 years at baseline. Individuals were not included if they had a diagnosis of a disabling psychiatric disorder or disabling physical illness.
