Objective:

To estimate the prevalence and distribution of anemia in Mexican women and their association with sociodemographic factors and diet diversity.

Materials and methods:

We analyzed information of women in childbearing age. The Ensanut 100k is a probabilistic survey that over-represents households with less economic capacity. Anemia was estimated using hemoglobin concentration. We collected sociodemographic and health information, food insecurity, and dietary diversity.

Results:

34.3% of the women presented anemia, belong to tertile 3 of welfare status is a protective factor for anemia (OR= 0.26, 95%CI 0.16-0.61), and living in a household with food security, as well as high diversity of the diet in rural women (OR= 0.57, 95%CI 0.36-0.92).

Conclusions:

It is necessary to implement actions of detection and early attention of the anemia in women in childbearing age, identification of its underlying causes, strengthening and reformulation of strategies to prevent it.
