AIM: Describe breast- and bottle-feeding patterns and the introduction of solid feeds and sugar containing drinks to the dietary intake of a cohort of urban Aboriginal infants in the first year of life. METHODS: Two hundred and seventy-four infants were recruited to a cohort study and information about infant nutrition was collected from their mothers during face to face interviews when the infants were aged 6-12 weeks, 7-8 months and 12 months old. RESULTS: 88.3% of mothers initiated breast-feeding, but only 43.8% of infants were exclusively breast-fed at 6-12 weeks. By 12 months of age 69.8% of babies had received fruit juice in their bottles, 59.8% received cordial. 64.5% of infants were given water in their bottles. The majority of infants had received 'fast foods' by 12 months of age with 56.2% had been given coca cola, 68% lemonade and 78% fried chips. CONCLUSIONS: This study highlights areas in which nutrition health promotion can be targeted to prevent common childhood health problems including promoting and supporting mothers to sustain breast-feeding and opportunities to reduce the sugar and fat intake among infants.
