Prevalence of anemia in the Mexican population: the analysis of Ensanut Continua 2022.

Abstract

Objective. To describe the magnitude of the prevalence of anemia in the Mexican population participating in the Encuesta Nacional de Salud y Nutrición Continua 2022 (Ensanut Continua 2022). Materials and methods. The Ensanut 2022 is a probabilistic survey. Venous blood was collected to estimated hemoglobin (Hb) using hemocue 201+, then Hb values were adjusted by altitude and anemia was defined using the World Health Organization (WHO) cut-off for age and sex. Prevalence and 95%CI were reported considering the complex sample design. Results. The prevalence of anemia was 6.8% in children aged 1-4y, 3.8% in children aged 5-11y, 10.1% in adolescents (12-19y), 15.8% in women (20-49y) and 10.3% in older adults (≥60y). Conclusions. Anemia affected mainly adult women. Is a need to identify its causes and associated factors to target interventions and avoid the intergenerational cycle of anemia.
