Objetivo. Entender y cuantificar la relación entre los perfiles socioeconómico y de aseguramiento en salud y el uso de servicios médicos ambulatorios en el contexto de la universalización de la salud en México. Material y métodos. Utilizando la ENSANUT 2012, se estimaron modelos de regresión multinomial para analizar el uso de servicios ambulatorios y sus factores asociados. Resultados. La población con mayor pobreza, menor nivel educativo y residente de zonas de alta marginación tiene menor posibilidad de usar servicios de salud ambulatorios. En contraste, tener un seguro de salud y mayores ingresos favorecen el uso e influyen en la elección del proveedor. Conclusiones. Persisten barreras en el acceso a la salud asociadas con la condición de pobreza y de protección social. Sin embargo, existe espacio para disminuir el efecto de estas barreras, abordando las restricciones en la oferta de los servicios y en la calidad percibida de los mismos.

Objective. To estimate the willingness to vaccinate against Covid-19 (acceptance) in the Mexican population and to iden­tify socioeconomic factors associated with vaccine hesitancy and refusal. Materials and methods. We estimated the acceptance, refusal and hesitancy proportions using data from the Covid-19 National Health and Nutrition Survey conducted from August to November 2020. Factors associated with re­fusal and hesitancy were explored using multinomial logistic regression. Results. Covid-19 vaccination acceptance was 62.3%, refusal 28.2% and hesitancy 9.5%. Refusal and hesitancy were associated with being female, having older age, lower educational level, lower socioeconomic status and working in the informal sector. Conclusion. National campaigns to incentivize vaccine acceptance need to consider specific subgroups were the likelihood of hesitancy and refusal is high. In Mexico, refusal and hesitancy were higher in vulnerable groups, and people at a higher risk of Covid-19 complica­tions and death.

Objetivo. Describir el diseño de la Encuesta Nacional de Salud y Nutrición 2021 (Ensanut 2021). Material y métodos. La Ensanut 2021 es una encuesta probabilística de hogares que forma parte de la serie de Ensanut Continua 2020-2024. En esta ocasión se describen el alcance, el muestreo, la medición y la organización logística. Resultados. Se planea obtener al menos 12 060 entrevistas de hogar completas a nivel nacional y 9 837 muestras para determinar seropositividad a SARS-CoV-2 a nivel nacional. Conclusiones. La Ensanut 2021 permitirá realizar inferencias regionales sobre la prevalencia de seropositividad a SARS-CoV-2 y también acumular información para realizar inferencias estatales en el año 2024.

Objectives: To describe the prevalence and correlates of depressive symptoms, generalized anxiety disorder (GAD), and perceived negative mental health impact during the SARS-Cov-2 pandemic in Mexico City and evaluate their association with adherence to stay-at-home directives.Methods: Baseline data from a cohort study of 2,016 Mexico City government employees were analyzed using multivariable logistic regression models.Results: Among participants, 17.2% had clinically significant depressive symptoms, 21.6% had probable GAD, and 15.2% reported that the pandemic has had a major impact on their mental health. Factors including the presence of COVID-19 symptoms, self-isolation, and economic difficulties were associated with poor mental health. The presence of depressive symptoms and general anxiety were associated with non-adherence to public health directives, particularly among those who might have experienced these symptoms for the first time during the pandemic.Conclusion: Our study is one of the first to document the population mental health burden during the SARS-CoV-2 pandemic in Mexico and to provide evidence of the potential role of mental health in the adherence to public health measures.
