Prevalence of breast-feeding and its correlates in Ho Chi Minh City, Vietnam

BACKGROUND: The health benefits of breast-feeding are widely acknowledged and breast-feeding is crucial for the survival of the infants in developing countries. The present study aims to elucidate the prevalence of breast-feeding and the possible risk factors affecting the breast-feeding of infants at the age of 3 months in Ho Chi Minh City, Vietnam after the World Health Organization and the United Nations Children's Fund launched "the Baby-Friendly Hospital" Initiative in 1989. METHODS: A cross-sectional study was conducted in the urban areas of Ho Chi Minh City, Vietnam in February, 2000. Two hundred and sixty mother-infant pairs were conveniently recruited in three child health centers in Ho Chi Minh City. Mothers of infants aged 6-12 months were interviewed and completed a well-structured questionnaire regarding the feeding types of the infant, the maternal knowledge, attitudes and behaviors related to breast-feeding. RESULTS: The results indicated that although about 86.4% newborns in the maternity wards and 88.5% infants at 3 months were at least partially fed with breast milk, the prevalence of breast-feeding were 57.4 and 53.1%, respectively. About 47.5% newborns were fed with breast milk in the first feeding. The multivariate logistic regression analysis shows that the risk factors for the introduction of breast milk substitutes at 3 months of age were maternal antenatal plan of mixed or artificial feeding (odds ratio (OR) = 6.59, 95% confidence interval (CI): 3.18-13.64, P < 0.001) and the supplement of breast milk substitutes in the maternity ward (OR = 4.30, 95% CI: 2.10-8.77, P < 0.001). Higher maternal education levels were beneficial to the continuation of breast-feeding. About 18.5% mothers had attended antenatal breast-feeding education. Most of the mothers (94.1%) and families (95.4%) indicated supportive attitudes to breast-feeding. CONCLUSION: The prevalence of breast-feeding was relatively low in Ho Chi Minh City, Vietnam. The antenatal education in breast-feeding needs to be improved and the implementation of the "Baby-Friendly Hospital" policy needs to be strengthened.
