Objectives: Community-based nutrition interventions aimed at influencing child dietary intake are rarely evaluated. We hypothesised that providing self-directed nutrition and parenting resources to parents living in rural northern New South Wales, Australia, would positively affect the dietary patterns of children ages 2 to 5 years.
Methods: A total of 146 parent–child dyads (76 boys, ages 2.0–5.9 years) were randomly assigned to either a 12-month parent-centred intervention involving self-directed education provided in CD and DVD formats, or a participant-blinded control group who received generic nutrition and physical activity information. Data were collected at baseline, 3, and 12 months.
Results: Total reported energy from nutrient-dense food groups and percentage energy from energy-dense, nutrient-poor foods were high at baseline relative to estimated total energy expenditure for child age. Using random effects modelling, there were significant group-by-time effects for a reduction in mean (standard deviation) total energy intake (EI) at 12 months (−461 kJ/day (196); P = 0.04). An intervention group-by-time effect on carbohydrate intake (−17.4 g/day (10.6); P < 0.05) was largely attributable to decreased consumption of breads and cereals (−180 g/day (80); P = 0.007). Decreases in energy-dense, nutrient-poor foods were not statistically significant.
Conclusions: The proportion of total EI from noncore foods in children in rural New South Wales is high and did not improve in response to a low-intensity nutrition intervention. Parents reported small changes in consumption frequency for core and noncore food intakes, leading to a reduction in total EI. Strategies to increase resource use such as prompting via e-mail are required to further explore the effectiveness of nutrition resource dissemination at a population level.
