简要总结
In the first study, to identify children at high and low risk for cardiovascular disease and study their nutritional and physical activity behaviors as they relate to cardiovascular disease. In the second study, to make yearly assessments over a four year period of diet and physical activity among children and their parents. The initial effort redefined and retested methods to collect data on dietary intake and activity levels of young children.
详细描述
BACKGROUND:
In the past several decades, relationships between various lifestyle behaviors and the development of cardiovascular risk factors have been identified. Nutritional status/eating behaviors and physical activity patterns both directly and indirectly are related to the development of coronary heart disease. For example, obesity, which may be a result of both eating and physical activity behaviors, greatly increases the risk of hypertension, hyperlipidemia, and diabetes mellitus, placing the individuals at greater risk for coronary heart disease. Dietary factors such as composition in fatty acids and cholesterol, composition in vegetable protein and complex carbohydrates, caloric excess and a high intake of salt also are related to the development of risk of coronary heart disease.
Physical activity in adults has also been correlated with coronary heart disease. Epidemiological research has demonstrated that increased physical activity is associated with reduced risk of myocardial infarctions. Regular physical exercise has been shown to have beneficial effects on relative weight and obesity and may act indirectly to beneficially affect hypertension, hypertriglyceridemia and glucose intolerance and raise HDL cholesterol levels. However, in 1985 when SCAN was initiated, little information was available concerning the development of nutritional status/eating behaviors and routine physical activity patterns in children.
Various psychosocial factors have been associated with increased risk of coronary heart disease. Among these factors are behavioral characteristics such as type A behaviors and coping styles to stressors. However, relatively little was known in 1985 concerning the development of such characteristics in children and when these characteristics became associated with risk of cardiovascular disease.
SCAN initiated on the recommendations of the Preventive Cardiology Branch Task Force Group in the Five Year Forward Plan 1982-1987, the Conference on School Health Education Research in the Heart, Lung, and Blood Areas, and the Clinical Applications and Prevention Advisory Committee of the National Heart, Lung, and Blood Institute. A Request for Applications was released in October 1984. In 1985, six grants were awarded as part of the Study of Children's Activity and Nutrition (SCAN).
