Childhood socioeconomic position and adult cardiovascular mortality: the Boyd Orr Cohort.

The relation between childhood socioeconomic position and adult cardiovascular mortality is examined in 3,750 individuals whose families took part in the Carnegie survey of family diet and health in England and Scotland between 1937 and 1939. The trend in coronary heart disease mortality across social position groups was not statistically significant at conventional levels (p = 0.12), while a strong linear trend was seen for stroke mortality (p = 0.01). Adjustment for the Townsend deprivation index of area of residence during adult life did not materially alter these findings, indicating that the effects of socioeconomic influences upon particular cardiovascular diseases differ according to the age at which they are experienced.
