Type of cows' milk consumption and relationship to health predictors in New Zealand preschool children

Abstract

Aims: New Zealand dietary guidelines recommend children from two years of age consume low- or reduced-fat milk. We aimed to investigate the predictors of type of milk consumption in preschool children.

Methods: Data were drawn from a cross-sectional study which enrolled preschool children (2-<5 years, n=1,329) from throughout New Zealand.

Results: Cows' milk was consumed regularly by 88% of children. Of these, 26% consumed plain low- or reduced-fat milk, while 74% consumed full-fat milk. The adjusted odds of consuming plain low- or reduced-fat milk were increased in older children: three-year old (OR=1.80, 95% CI 1.29-2.50); four-year old (OR=1.93, 95% CI 1.38-2.72) versus two-year old children, and were decreased in Māori (OR=0.56, 95% CI 0.36-0.88) and Pacific children (OR=0.32, 95% CI 0.12-0.86) compared with New Zealand European children. Approximately 18% of children were overweight/obese. The odds (adjusted for socio-demographic characteristics) of consuming plain low- or reduced-fat milk were increased in overweight children (OR=1.74, 95% CI 1.20-2.54) than normal weight children.

Conclusions: The type of milk consumed by preschool children varies with child demographics and anthropometry. Further research is warranted to investigate caregivers/parents' knowledge about dietary guidelines and to determine the causal relationship between obesity and milk type consumption. The findings of the current study may have important implications for developing and shaping interventions and in helping shape public health policy and practice to promote cows' milk consumption in preschool children.
