OBJECTIVE: To investigate the growth and feeding practices in first-generation Vietnamese infants living in Australia. DESIGN: Cohort study. SETTING: The study was conducted between 1999 and 2002 in Sydney. SUBJECTS: A total of 239 Vietnamese women were recruited randomly from antenatal clinics, and of these 210 were initially seen. During the first year, 20 cases (9.5%) were lost to follow-up. Data were collected at 0.5, 2, 4, 6, 9 and 12 months. RESULTS: Vietnamese infants were significantly longer and heavier than reference data (both P<0.0001). The Vietnamese infants had a significant decline in weight growth with age compared with reference data (P<0.001). The Vietnamese infants had marginally higher s.d. score for ideal weight for length than reference data (P=0.044). There was a significant decline in ideal weight for length with age compared with reference data (P=0.0065). Both parents were significantly shorter (mean s.d. height scores: -1.5+/-0.8 (mother) and -1.8+/-0.8 (father)) than reference data (P<0.001). The incidence of breast feeding was 79%, but half of the breast feeding women had stopped breast feeding by 3 months. A total of 162 (79.8%) infants were given infant formula within the first week, of whom 131 (80.1%) were fed infant formula within the first 24 h after birth. CONCLUSIONS: Vietnamese infants in this study had growth comparable with reference data despite their parents being shorter than reference data. Breast feeding duration was short with infant formula being introduced early.
