SMS1947 Scottish Mental Survey of 1947, BMI body mass index, MHT IQ Moray House Test intelligence quotient, NART National Adult Reading Test, RSPM Raven’s Standard Progressive Matrices. Sample summaries are provided for the entire 36-Day Sample in 1947, for those who participated in the SMS1947, for the follow-up participants who provided physical measurements in older age, and for those who also completed cognitive testing. There was a significant sex difference in late-adulthood height, which is therefore presented separately for men and women
