BACKGROUND: Breastfeeding practices might be influenced by migration to another country. Although the "healthy migrant effect" is commonly reported in epidemiology, evidence for it in breastfeeding practices is weak. OBJECTIVES: This study aimed to compare the initiation and duration of breastfeeding between Chinese Australian migrants and Chinese mothers in mainland China and test the healthy migrant effect in Chinese Australian migrants in Perth, Western Australia. METHODS: A survey was undertaken of 239 Chinese mothers living in Perth and 1844 mothers living in Chengdu, Sichuan Province, PR China, with a response rate of 96.7% and 87.8%, respectively. RESULTS: The breastfeeding initiation rate in Chinese Australian mothers (94.1%) was higher than in mothers in China (86.2%, P < .001). Chinese Australian mothers also had a longer breastfeeding duration, greater "full breastfeeding" rate at 6 months, and greater "any breastfeeding" rates at 6 and 12 months. After controlling for potential confounding variables, the results of the binary logistic regression analysis showed that the location of the mother (Australia or China) was associated with breastfeeding practices. Chinese mothers living in Chengdu were less likely to initiate breastfeeding (odds ratio = 0.47, 95% confidence interval, 0.25-0.89) and breastfeed their babies at 12 months (odds ratio = 0.48, 95% confidence interval, 0.33-0.69) than Chinese mothers in Perth. CONCLUSION: The higher breastfeeding initiation and longer breastfeeding duration by Chinese migrant mothers in Perth than mothers in Chengdu suggest a "healthy migrant effect."
