RESUMO
Background: Food fortification and micronutrient supplementation are public health strategies to improve micronutrient status in Guatemala; their population effectiveness has not been evaluated in recent years. Objective: We evaluated trends in food fortification, micronutrient supplementation, anemia, and iron deficiency among nonpregnant women aged 15-49 y [women of reproductive age (WRA)] and children 6-59 aged mo [preschool age children (PSC)]. Method: Nationally representative serial cross-sectional surveys were used to assess changes in hemoglobin, anemia, ferritin, iron deficiency, iron deficiency anemia, and self-reported consumption of fortifiable foods and micronutrient supplements during 2008/2009, 2013, 2015, 2016, 2017/2018, and 2018/2019. Predictors of hemoglobin and ferritin were assessed using generalized linear mixed models adjusted for survey year as random effects, and the consumption of fortifiable foods, supplements, and other potential confounders were fixed effects. Results: Multiple micronutrient powder consumption among PSC during the previous 3 mo was 53.3% (95% CI: 49.4, 57.2) in 2013 and 33.6% (28.8, 38.4) in 2018/2019. Anemia among PSC was 11.3% (8.0, 14.5) in 2008/2009 and 6.1% (3.6, 8.6) in 2018/2019. Anemia among WRA was 10.7% (7.2, 14.2) in 2008/2009 and 3.9% (2.7, 5.2) in 2018/2019. Iron deficiency among PSC was 15.5% (12.1, 19.0) in 2008/2009 and 10.9% (7.4, 14.5) in 2016 (lowest), but 17.1 (13.3, 21.0) in 2017/2018 (highest). Iron deficiency among WRA was 14.9% (11.6, 18.2) in 2008/2009, 13.8% (11.8, 15.8) in 2013 (lowest), and 18.9% (16.3, 21.6) in 2017/2018 (highest). Wheat flour/bread consumption was positively associated with hemoglobin among PSC, and sugar consumption was positively associated with hemoglobin among WRA. The reported consumption of fortifiable foods was not associated with ferritin among PSC or WRA. Conclusions: Guatemala has implemented multiple food fortification strategies, and anemia has declined. Increases in iron deficiency in 2017-2019 warrant further attention. Secular trends toward poverty alleviation, education, and development might be responsible for changes not explained by the micronutrient interventions evaluated.
RESUMO
Desde 1993 el personal local de salud del Ministerio de Salud de las áreas de Suchitepéquez y El Quiché en Guatemala, y del departamento de Chalatenango en El Salvador, con el apoyo del INCAP, realizan esfuerzos en procesos del mejoramiento de la calidad de los servicios dentro de las actividades de Control de Enfermedades Diarréicas (CED) y el Cólera. El proceso del mejoramiento de la calidad comprende las evaluaciones rápidas de calidad, priorización de problemas e identificación de opciones de solución y la implementación, supervisión y monitoreo del mejoramiento de la calidad. En esta Monografía se describe en forma breve la experiencia de las áreas de salud de Guatemala y El Salvador, que se han lanzado a la aplicación de cada una de las etapas mencionadas anteriormente. En los apéndices se proveen las herramientas e instrumentos que se han utilizado en este desarrollo.
