With the possible exception of sub-Saharan Africa, the prevalence of stunting is rapidly decreasing, but child overweight is increasing [43]. Undernutrition in children is expected to be associated with greater child food insecurity. The magnitude and direction of any association of overnutrition with child food insecurity probably depends on the severity of the food insecurity. In part, the slippage among these constructs reflects limitations in the data that are currently available.
