There are few comparable studies by which to consider our results, especially given our median follow-up of almost 60 years in this cohort. Among men who were students at Glasgow University during 1948 to 1968, a 10-mm Hg increase in systolic blood pressure measured at around age 20 years was associated with a 15% increased risk of CHD mortality (12), which remained following multivariable adjustment (9). More recently, blood pressure in late adolescence was positively associated with early incidence of CHD and stroke in a large cohort of Swedish men (10).
