Although there is a sizable literature on determinants of health-related habits in adults, relatively little attention has been paid to influences on health habits in children. The purpose of this study was to (a) develop practical, reliable, and valid measures of knowledge of and preference for cardiovascular disease-related diet and exercise behaviors in children, and (b) assess parental influences on children's knowledge and preference. Eighty-one 4- to 8-year-old children from diverse ethnic backgrounds and their parent or legal guardian participated. Children were presented with 15 attractive photo-pairs of foods. One photograph was of a "healthful" food or activity, and the other was "unhealthful." They were asked to identify which food/activity of the pair they preferred, and which one they thought was more healthy. Children were retested after 1 week to determine test-retest reliability. Validity of the preference tests was determined by giving the child actual choices of the same activity and food pairs. Validity of knowledge tests was determined by testing children after an educational intervention session. The alpha coefficients, test-retest reliabilities, and validity data generally indicated that food preference and knowledge tests had adequate psychometric properties, but the physical activity scales did not. Very few parental influences on health-related behavior were detected.
