Abstract

Aims To examine the association of physiological, behavioural and social characteristics in pre-middle age with future total and cardiovascular disease (CVD) mortality. Methods and results Risk factor data on 1503 individuals aged 16-35 years at baseline were collected in two prospective cohort studies using standard protocols. Their association with total and CVD mortality ascertained during 40 years of follow-up was summarized using Cox proportional hazards regression. A median follow-up of 39.6 years gave rise to 255 deaths (103 from CVD). In age-adjusted and sex-adjusted analyses, impaired lung function [one standard deviation increases in forced expiratory volume in 1 s: hazards ratio 0.69; 95% confidence interval 0.55, 0.86; and in forced vital capacity: 0.76; 0.59, 0.98], current cigarette smoking (4.16; 2.22, 7.80) and higher alcohol consumption (one standard deviation increase in standard units consumed: 1.20; 1.02, 1.41) were associated with CVD. In fully adjusted analyses associations generally held. For total mortality, these factors and obesity and socioeconomic disadvantage were predictive. Conclusion A range of risk factors measured before middle age were related to risk of total and CVD mortality up to four decades later, indicating that public health interventions should be implemented earlier in the life course than is currently the case.
