Discussion
• 2005 – 2008, SBR is 112.3, equivalently to the national rate (111/100 – VPHC, 2009)
• Parents choose sex of child (boy) at the first child (114/100) or the 3th one and above (176/100)
• SBR is highly related to the sex of preceding child/children, mother’s education, occupation and SES.
Recommendation
• To researchers:
• To local policy makers:
• To community:
