Cohort Profile Update: The Stockholm Birth Cohort Study (SBC)
Abstract
The Stockholm Birth Cohort Study (SBC) was set up in 2004/2005 to investigate how childhood living conditions and experiences are related to life-course health, occupation and income. Briefly, the SBC was established by a probability matching of two longitudinal, anonymized datasets: the Stockholm Metropolitan Study (SMS) and the Swedish Work and Mortality Database (WMD). The former dataset contains information on all individuals who were born in 1953 and lived in the greater metropolitan area of Stockholm in 1963 (n1⁄4 15 117). Register and survey follow-ups were carried out up until 1986 when the SMS was de-identified. The latter dataset consists of all individuals who were born before 1985 and lived in Sweden in 1980 and/or 1990 (n1⁄4 9 428 526). The WMD includes information on income, work, education, family formation, in-patient care and mortality for the period 1981–2009. The probability matching rendered it possible for researchers to follow 14 294 members of the SMS cohort from birth (1953) to the age of 56 (2009).
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
