• Background Anemia status is frequently assessed in cross-sectional surveys. Recently, the assessment of acute phase proteins (APPs) has become more common, primarily for iron and vitamin A biomarkers. Although the so-called “anemia of infection” has been known for years, the relationship between APPs and anemia has been infrequently presented. Objective To assess the relationship between elevated α1-acid glycoprotein (AGP) and the prevalence of anemia among preschool children. Methods A nationally representative household-based cross-sectional survey was conducted in 2003–05 in Nicaragua. Blood samples were collected from preschool children 6 to 59.9 months of age and tested for hemo- globin and AGP. Data were also obtained on sex, weight, height, use of iron supplements, maternal education, and urban or rural status. Results Among the 1,420 children assessed, the overall prevalence of anemia was 20.2% and the prevalence of elevated AGP was 24.0%. Children with elevated AGP had an anemia prevalence of 27.9%, compared with 17.8% among those with a normal AGP, for a crude prev- alence odds ratio (POR) of 1.8 (p = .010). Accounting for age, maternal educational level, and year of survey using logistic regression, the adjusted POR for the association between elevated AGP and anemia was 1.5 (p = .053). Conclusions Children in this survey with an elevated AGP had a higher prevalence of anemia, although after controlling for covariates the p-value did not indicate a statistically significant difference (p = .053). It may be helpful to account for APPs, when this information is available, for purposes of comparing anemia prevalence across populations or within a population over time.
