Cardiovascular health promotion in children: program and policy implications

The Interaction Model of Client Health Behavior as a Conceptual Guide in the Explanation of Children's Health Behaviors

This study used the Interaction Model of Client Health Behavior (IMCHB) as a conceptual guide to explain the correlates of children's diet and physical activity and explore the relationships of sex with their diet and physical activity of the school-aged child. A descriptive correlational study was conducted on 371 fifth-grade students and their parents. Information on the family's demographics, health experience, social influence, and environmental resources was collected, as well as data on the children's intrinsic motivation, cognitive appraisal, and affective response to food/physical activity. Children's self-reports on diet and physical activity were collected, as were parents' self-reports on health habits. Food preferences and diet self-efficacy explained the most variance in diet behavior for girls and boys. Girls scored healthier on food preferences and diet self-efficacy than did boys, but no difference was detected in their diet behavior. Girls participated in more low-intensity physical activity, but boys participated in more high-intensity physical activity than did girls. Findings provide strong support for the use of the IMCHB to explain children's diet but weak support for the explanation of children's physical activity. Further study of additional factors predictive of physical activity is indicated.

Effectiveness of a cardiovascular health promotion education intervention on the attitudes of urban African American school-age children

African American children are at risk for high rates of morbidity and mortality associated with cardiovascular (CV) disease as they become adults, yet little is known about the effectiveness of CV risk-reduction interventions in African American children. This study explored the effectiveness of a concentrated CV health promotion educational program on health-related attitudes of 76 African American children enrolled in a mid-southern school system. The Children's Cardiovascular Health Promotion Attitude Scale was used to examine differences in attitude prior to and 2 weeks following a focused health education intervention. Results demonstrate that children have preconceived attitudes regarding practice of health behaviors and that these attitudes are modifiable with age and developmental level specific educational interventions. Findings indicate the need for health care providers to assume more active roles in reducing the risk of future CV disease and death in African Americans through health promotion education of individuals who influence the development of children's attitudes.
