The dietary outcomes of a school-based heart health promotion program in a low-income, multiethnic, inner-city neighbourhood of Montreal, Canada, were investigated. Eight intervention schools and sixteen control schools participated in the project from 1993 to 1997. Twenty-four hour recall data, as well as data on anthropometric and sociodemographic characteristics, were collected from a subsample of all students in grades 4--6 (aged 9--12 years) at baseline (n = 498), after two years (n = 491), and after four years (n = 347). There were no significant differ in nutrient intakes between 1995 and 1997, so these data were combined for analyses. Compared to students in control schools, students exposed to the program had a significantly increased mean intake of vitamin C per 1000 kcal (4184 kJ) (p = 0.0013). Compared to students in designated intervention schools at baseline, mean make of vitamin C per 1000 kcal was significantly increased (p = 0.002) and mean folate intake was significantly domed (p = 0.0058) in exposed to the program. When the intervention group was restricted to only those students who had received 16 hours or more of program exposure (n = 113), there were no significant differences in any nutrient intakes when compared to control students or students in intervention schools at baseline. This program was unsuccessful in changing nutrient intakes of school-aged children, contributing further evidence that conscious dietary change is difficult to achieve by means of a school-based program with a reasonable number of curriculum hours.
