Undernutrition of children in Massachusetts.

Over the past 10 years, seven separate studies of children at risk from undernutrition in Massachusetts have been performed. The surveys have ranged from a statewide health center-based investigation to a house-to-house survey in a public housing project. All included children between 1 and 6 years of age. Chronic undernutrition was defined as a height-for-age less than the 5th percentile of the National Center for Health Statistics growth charts, and acute undernutrition was defined as a weight-for-height less than the 5th percentile. The prevalence of chronic undernutrition was greater than expected in four surveys, whereas no acute undernutrition was observed. The prevalence of obesity, defined as a weight for height greater than the 95th percentile, was increased in four of the seven surveys. These data suggest that chronic undernutrition is increased among children at risk in Massachusetts.
