This study examined the association between community rates of iron deficiency in chilfdren and sociodemographic characteristics of Massachussets communities.
Between April 1990 and March 1991,238 273 Massachussets children 6 through 59 months of age were screened ; iron deficiency was defined as an erythrocyte protoporphyrin concentration of 0.62 mumol/L or higher and a blood lead level of less than 1.0 mumol/L. Sociodemographic data were obtained from the 1990 US Census.
Five percent of communities had iron deficiency rates greater than 13.9 per 100 children screened.
Iron deficiency rate was positively associated with proportion of Southeast Asians (odds ratio [OR]=1.10,95% confidence interval [CI]=1.08,1.12), proportion of Hispanics (OR=1.008,95% CI=1.002,1.013), and high school incompletion (OR=1.028,95% CI=1.020,1.035).
Similarly, an examination of three Massachussets cities indicated that the iron deficiency rate was higher for children with Southeast Asian (relative risk [RR]=3.6,95% CI=3.3,3.8) and Hispanic (RR=1.6,95% CI=1.5,1.8) surnames than for all other children.
Wide variation exists in iron deficiency rates for children in Massachussets communities.
Community iron deficiency was associated with low socioeconomic status and high proportions of Southeast Asians and Hispanics.
