Public policy positions breastfeeding as a key strategy to protect vulnerable children from household food insecurity.1,2 Using data from a Canadian population-representative survey, Orr and colleagues report that household food insecurity negatively affects the duration of exclusive breastfeeding.3 They show that mothers with severe household food insecurity breastfeed for a significantly shorter time than mothers in food-secure households or in marginally and moderately food-insecure households. However, among Inuit mothers in Canada with a high prevalence of household food insecurity, this difference does not seem to be apparent.4
In emerging nations, widespread poverty often results in extreme household food insecurity, which, in contrast to households in developed nations, may lead to exclusive breastfeeding by way of “last resort exclusive breastfeeding.”5 Mothers practise exclusive breastfeeding because they have no alternative food source for their infants.5 Nevertheless, they may have perceptions of breast milk insufficiency and feelings of weakness.6 These polar differences may reflect the spectrum for household food insecurity, from marginal to severe and extreme, that may not be captured in categorical data collection.
The findings of Orr and colleagues reinforce prior impressions that a breastfeeding paradox exists, whereby “women who can least afford to buy infant formula and whose infants can benefit most from the health-promoting qualities of breast milk are the least likely to breastfeed.”1,2 Recognition of the full spectrum of household food insecurity needs incorporation into policies and programs that may strengthen food security and support mother and child nutrition.
