Iron deficiency anemia among young children is a large health problem. However, there is little information about the prevalence of anemia among young infants because it has been assumed that normal, breast-fed infants have adequate iron stores until 4-6 mo of age. We analyzed cross-sectional data from the HKI/GOI Nutrition and Health Surveillance System in rural Java, Indonesia from Sept. 1999 to Feb. 2001 for hemoglobin (Hb) of 3- to 5-mo-old breast-fed infants (n = 990) and related factors. The prevalence of Hb < 90 g/L was 13.4%, < 100 g/L, 37%, and < 110 g/L, 71%. Multiple logistic regression analysis revealed that normal birth weight infants (>2500 g) of anemic mothers (Hb < 120 g/L) had an odds ratio (OR) [95% confidence interval (CI)] of 1.81 [1.34-2.43] to have a low Hb (< 100 g/L) compared with infants of nonanemic mothers with a normal birth weight. Infants of nonanemic mothers but with low birth weight had an OR of 1.15 [0.61-2.16], and those with low birth weight and anemic mothers of 3.68 [1.69-8.02]. Other risk factors included stunting (OR 1.70 [0.97-2.95]), a young mother (<20 y, OR 1.54 [0.95-2.49]), lower maternal education and living in West Java or East Java. Considering that maternal postpartum Hb reflects Hb during pregnancy, that anemia among mothers in this population is due mainly to iron deficiency, and that children born to anemic mothers are at higher risk of a low Hb, we hypothesize that low infant Hb in this population is due to iron deficiency. Intervention studies in iron deficient populations should test this hypothesis. [ABSTRACT FROM AUTHOR]

The study was designed to determine whether population-specific hemoglobin cut-off values for detection of iron deficiency are needed for Indonesia by comparing the hemoglobin distribution of healthy young Indonesians with that of an American population. This was a cross-sectional study in 203 males and 170 females recruited through a convenience sampling procedure. Hemoglobin, iron biochemistry tests and key infection indicators that can influence iron metabolism were analyzed. The hemoglobin distributions, based on individuals without evidence of clear iron deficiency and infectious process, were compared with the National Health and Nutrition Survey (NHANES) II population of the United States. Twenty percent of the Indonesian females had iron deficiency, but no male subjects were iron deficient. The mean hemoglobin of Indonesian males was similar to the American reference population at 152 g/L with comparable hemoglobin distribution. The mean hemoglobin of the Indonesian females was 2 g/L lower than that of the American reference population, which may be the result of incomplete exclusion of subjects with milder form of iron deficiency. When the WHO cutoff (Hb < 120 g/L) was applied to female subjects, the sensitivity of 34.2% and specificity of 89.4% were more comparable to the test performance for white American women, in contrast to those of the lower cut-off. On the basis of the finding of hemoglobin distribution of men and the test performance of anemia (Hb < 120 g/L) for detecting iron deficiency for women, it is concluded that there is no need to develop different cut-off points for anemia as a tool for iron-deficiency screening in this population.
