(Croatia and Serbia)
Two countries from the former Yugoslavia, Croatia and Serbia, provided five cohorts to the Seven Countries Study. The two Croatian cohorts differed largely in diet, a Mediterranean diet in Dalmatia and an Eastern European diet high in animal fat in Slavonia.
The three Serbian cohorts differed largely in socio-economic status and an Eastern European style diet high in meat and/or dairy. The Serbian cohorts later joined the HALE project.
The cohort of Dalmatia was of all men of proper age from a number of villages along the Adriatic Sea coast, south of the town of Split in Dalmatia, Republic of Croatia, within former Yugoslavia. All were characterised by a Mediterranean, high plant diet.
The cohort of Slavonia consisted of all men from villages centered around Dalj in the plain of Slavonia, Republic of Croatia, within former Yugoslavia in which the diet was presumably high in animal products.
The cohort of Velika Krsna was made up of a “chunk sample” of all men in the rural village of Velika Krsna located not far south from Belgrade, Republic of Serbia in the former Yugoslavia.
The cohort of Zrenjanin was made up of men working in an agro-industrial cooperative located in the town of Zrenjanin, north of Belgrade, Republic of Serbia in the former Yugoslavia.
The cohort of Belgrade was made up of faculty members of the University of Belgrade, located in the capital of the Republic of Serbia in the former Yugoslavia.
