Parental knowledge, perceptions and consumption of milk and alternatives relates to intakes of young children 2–8 y of age

A low intake of milk and alternatives is concerning for children, since vitamin D, calcium and other nutrients in these foods are important for growth and development. Canadian research is ambiguous on how parental nutrition knowledge impacts the dietary intake of their children. Because of this, the objective was to assess the relationship between parental knowledge/perceptions of milk and alternatives and the intake of their child. This was a cross sectional analysis, during April and May 2015, of healthy participants (BMI z‐score > −2 and < 2), 2–8 y (n= 49) from a 6 month randomized vitamin D trial (clinicaltrials.gov: NCT02387892) in Montreal, Canada. The self‐reported parental knowledge and perceptions survey had 2 sections, one about general knowledge and perceptions and the second had specific questions about their child. Milk and alternatives and vitamin D intake were assessed using a validated 30 day food frequency questionnaire (FFQ). Pearson partial correlations, Bland‐Altman plots of agreement and mixed model ANOVA with Bonferroni post hoc testing were used. The participants (5.6 ± 1.9 y) were 59% (29/49) male, had mean BMI z‐scores of 0.65 ± 0.84, and only 2% (1/49) of children did not reach the recommended 2 servings/day of milk and alternatives by Canada's Food Guide (CFG). Sixty seven percent of families had incomes above $65,000 Canadian and 70% of parents had university level education. There was a significant partial correlation between parental milk and alternatives intake and FFQ child milk and alternatives intake (r = 0.59, p = 0.001). Also, when parents consumed milk and alternatives at meals with their child, children consumed significantly more servings of this food group throughout the day (). There was a small bias (0.314, 95% CI: −2.56 to 3.19) between the FFQ milk product intake and the perceived milk and alternatives intakes (). Though 82% of parents correctly identified CFG serving sizes of fluid milk, less than 25% correctly identified the serving sizes of yogurt and cheese (). Sixty three percent of parents thought the number of servings of milk and alternatives that children needed per day was higher than the CFG recommendations. Non‐white children consumed significantly more (p < 0.05) milk and alternatives than white children. Age and sex however, did not associate with milk and alternatives intake. These results suggest that parental milk and alternatives intake as well as knowledge of CFG may have a significant impact on the amount of milk and alternatives served to children. Future longitudinal research should test whether educating parents about milk and alternatives significantly changes the amount of these products they serve to their young children.
