Prevalence of iron deficiency was stable and anemia increased during 12 years (2006-2018) in Mexican women 20-49 years of age.

Objective. To compare the prevalence of women 20-49 years of age with iron deficiency anemia (IDA), iron deficiency with no anemia (IDNA), and non-ID anemia (NIDA) in comparison during 2006, 2012 and 2018, and their association with sociodemographic characteristics and nutritional status. Materials and methods. Ensanut 2006, 2012 and 2018-19 are comparable for measurements of anemia (hemoglobin) and Iron deficiency (ID, by ferritin). Both measurements combined were compared with year of surveys and other dependent variables using a multinomial regression. Results. In 2006, the total prevalence of anemia was 14.9% and ID 29.0%, the prevalence of IDA was 8.35%, of IDNA 20.5%, and NIDA 6.6%; in 2012, the total prevalence of anemia was 13.3%, ID was 9.6%, IDA 8.6%, IDNA 21.0% y NIDA 4.7%; in 2018 total prevalence of anemia was 21.4%, of ID 25.7%, IDA 10.5%, IDNA 15.2% and NIDA 10.9%. Conclusions. The total prevalence of anemia increased 6.5 pp between 2006 and 2018, IDNA reduced, IDA had no significant changes, the mayor increase (4.3 pp) occurred in NIDA. [ABSTRACT FROM AUTHOR]
