Public Policy to Promote Healthy Cardiovascular Lifestyles in Children

摘要

Health policy is an important component of prevention of cardiovascular disease (CVD) and promotion of health in childhood and adolescence, when major health behaviours are formed. Development of CVD-related health policy begins with continuous systematic collection, analysis, and interpretation of health-related data to establish the baseline prevalence of CV risk factors and behaviours. These findings allow identification of problems, initiation of focused research, and development of evidence-based interventions. Ultimately, these results inform development and implementation of population-level policies. This review focuses on CVD health-promotion policies in North American youth, for whom health surveillance is an ongoing part of public health policy, providing direct, objective, measurements of growth, lipids, blood pressure, physical activity and tobacco exposure for development of CV health research and policy. When national surveillance data identified significant risk of CVD in youth in the 1970s, major pediatric epidemiologic studies established the strong association between these risk factors and behaviours in childhood and the initiation and progression of atherosclerosis. This knowledge promoted development of the targeted public policies, which are reviewed in this paper. Public policy can directly and positively address cardiovascular health promotion in youth; the effective approach to smoking cessation exemplifies this. For more complex risk factors and behaviours, health policy can be a significant element in a comprehensive CV health promotion program.
