The Northern Finland Birth Cohort Studies is an epidemiological and longitudinal research program which aims to promote health and well-being of the population. The prospective data collected from the Northern Finland forms a unique resource, allowing to study the emergence of diseases which can be based on genetic, biological, social or behavioural risk factors.

NFBC includes two longitudinal and prospective birth cohorts of women and offspring collected at 20-year intervals from the same provinces of Oulu and Lapland: The NFBC1966 was set with an expected date of birth in 1966, comprising of 12,068 mothers and 12,231 children (prospective data collection from maternity cards since 16th gestational week on average), and the NFBC1986 with an expected date of birth between July, 1st 1985 and June, 30th 1986, comprising 9,362 mothers and 9,479 children (prospective data collection from 10th gestational week).
