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

Abstract

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 com-parison 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.
