Sex Ratio at Birth in Vietnam: Results From Data in CHILILAB HDSS, 2004 to 2013

This study aimed to explore the association of demographic and socioeconomic characteristics and imbalanced sex ratio at birth (SRB) in Chi Linh district, Hai Duong. The data were collected from a longitudinal study using a community-based periodic, referred as Chi Linh Health and Demographic Surveillance System (CHILILAB HDSS) during 2004 to 2013. A total of 7568 children were analyzed. Results showed that SRB in Chi Linh dramatically increased to the imbalanced sex ratio (114.6 boys to 100 girls) by 2013. SRB was associated with birth order and sex of preceding siblings. SRB was extremely high among families without any sons (136/100). SRB was highest among families having third or more children (175/100). Imbalanced SRB was more likely to occur among women working in small business/homemakers and others, women who attained high education level, and women in wealthy households. We suggested further efforts to tackle imbalanced SRB in periurban areas in Vietnam

IntroductionBreastfeeding has many benefits for mothers, children, and the environment over both the short and longr-term. Prenatal intention to breastfeed is a powerful predictor of short-term breastfeeding outcomes.ObjectiveThis study aims to analyze breastfeeding intentions, including the intention to feed infants with breastmilk only and to continue exclusive breastfeeding to 6 months among pregnant mothers in Hanoi, Vietnam.MethodsThe analysis included 1230 singleton mothers, between 24- and 36-weeks’ gestation, who attended antenatal clinics in two hospitals in Hanoi in 2020.ResultsThe proportion of mothers with an “breastfeeding intention” (i.e., intention to feed an infant with breastmilk only) and “exclusive breastfeeding intention” to 6 months was 59.9% and 41.7%, respectively. Mothers who were 25 years or older (aOR = 1.35, 95%CI:1.00–1.81), had an undergraduate educational degree or higher (aOR = 1.38, 95%CI: 1.08–1.76), had observed another woman breastfeeding (aOR = 1.43, 95%CI: 1.03–2.00), were not living with parents-in-law (aOR = 1.34, CI: 1.05–1.70), and were multiparous (aOR = 1.60, 95%CI: 1.16–2.19) had higher odds of “exclusive breastfeeding intention” to 6 months. Among primiparous women, those who thought their husbands support breastfeeding were more likely to intend to feed an infant with breastmilk only. Among multiparous women, feeding the previous child with breastmilk exclusively before the introduction of complementary foods and not giving solid foods together with water until 6 months, were significant predictors for both breastfeeding intentions.ConclusionMothers without exclusive breastfeeding experience should be provided with greater support to promote exclusive breastfeeding intention and outcomes.</div
