Prevalence of anemia and associated factors were analyzed in mothers (n = 1,022) and their children under 5 years of age (n = 1,242) in Pernambuco State, Brazil, 2006. This was a cross-sectional population-based study with a probabilistic sample in an urban and rural area. Anemia was diagnosed by hemoglobin level (children < 11.0 g/dL, women < 12.0 g/dL) using HemoCue. Univariate and multivariate analyses used Poisson regression with robust adjustment of standard error, adopting a hierarchical model for determination in children with anemia as the outcome. This same procedure was not applied to mothers because of the small number of associated factors in the univariate analyses. Anemia prevalence was 16.4% in mothers and 34.4% in children. Anemic as compared to non-anemic mothers showed a prevalence ratio of 1.44 (95%CI: 1.21-1.72) for anemia in their children, maintaining similar values in the adjusted model (PR = 1.39: 95%CI: 1.16-1.66). Anemia prevalence in children was double that of mothers, with the final model showing only one common factor: per capita family income.

01:27Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

When all four heme groups are bound to oxygen, the resulting molecule is called oxyhemoglobin. As a result, arterial blood...

History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
01:14Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
