differences in postnatal depression" Australian J. of Public Health

had 2x the risk of having PND at 8months compared with women who breastfed
from birth. Women who had stopped  breasfeeding by 3 months had 1.76x the
risk of having PND at 8 months compared with those who were still
breastfeeding at 3 month. This study was population based. The researchers
sent out questionaires to all mothers who had given birth during a
particular week in Victoria.119 out of 771 were found to be depressed on the
Edinburgh Postnatal Depression Scale, having a score of 13 or over. Carolyn
