Objective: To estimate the prevalence of inadequate iron intakes and identify socio-demographic factors associated with iron intakes of Australian children aged 2-5 years.
Methods: Data from the 2011-12 National Nutrition and Physical Activity Survey component of the Australian Health Survey were analysed (n = 783, 2 to socio-demographic factors (age and sex of child; and adult-pair's country of birth, education level, employment status, area-level disadvantage quintile, food security status, household type, and household size) and iron intakes were assessed via linear regression accounting for the complex survey design.
Results: Mean (SD) iron intakes for pre-schoolers were 7.9 (1.9) mg/day and the prevalence of inadequate iron intake for this age group was 10.1% (95% CI: 7.9%, 12.1%). Male sex (mean difference between boys and girls: -0.22 [95% CI: -0.03, -0.41] mg/day; P = 0.022) and age (each additional year was associated with 0.11 [95% CI: -0.22, -0.00] mg/day lower iron intake; P = 0.048) were negatively associated with pre-schooler iron intakes.
Conclusions: Pre-schooler energy-adjusted iron intakes were greater for females compared to males. Poor iron intakes continue to be a problem for some children beyond the second year of life as iron intakes were inadequate for 10% of Australian pre-schoolers. Intervention strategies aiming to improve iron intakes in Australian pre-schoolers, with emphasis for boys and older children, should be considered.
