Improving dietary habits of children: effects of nutrition education and correspondence training.

Evidence that a significant number of children are exposed to risk factors associated with coronary heart disease has prompted health care professionals to develop programs designed to encourage the early development of a healthy life style. The present study used a multiple baseline approach to examine the effects of two procedures on the snack selection behavior of 25 third grade children. In children who selected non-nutritious rather than nutritious snacks for more than 40% of the baseline observations, nutrition education alone had little or no impact on their selection of snacks. However, with the implementation of correspondence training, in which a reward was made contingent upon carrying out a stated intent to choose a nutritious snack, the children consistently chose nutritious snacks. These results indicate that correspondence training may be an efficient and cost-effective way to improve dietary habits of young people.
