ABSTRACT

BACKGROUND: Between 2020 and 2021, Mexico documented 2.21 million fatalities, out of which 25.3% were attributable to SARS-COV-2 infection. OBJECTIVES: To evaluate COVID-19 mortality during 2020-2021, determine its impact on national- and state-level life expectancy at birth, and in a group of selected countries of the region, as well as to analyze it according to sociodemographic profiles. MATERIAL AND METHODS: Data from the Global Burden of Disease 2021 study were used to report mortality, the impact on life expectancy and underlying causes between 2019 and 2021. These data were evaluated from the perspective of response to the pandemic and according to the sociodemographic structure based on a quadratic regression model. RESULTS: Between 2020 and 2021, 708,971 excess deaths were recorded, which decreased life expectancy at birth by 4.6 years; 76% of this reduction was attributed to COVID-19. The COVID-19 mortality rate was higher than expected according to the sociodemographic conditions of the states. CONCLUSIONS: In Mexico and the countries of the region, the pandemic was devastating and generated regressions in life expectancy at birth, which varied from two to nine years. It is not clear why the effect was so different between countries and within Mexico.


ANTECEDENTES: Entre 2020 y 2021, México experimentó 2.21 millones de defunciones, de las cuales 25.3 % estuvo relacionado con infección por SARS-COV-2. OBJETIVOS: Evaluar la mortalidad por COVID-19 en 2020-2021, determinar su influencia en la esperanza de vida al nacer a nivel nacional, estatal y en países seleccionados de la región, así como analizarla en función del perfil sociodemográfico. MATERIAL Y MÉTODOS: Se utilizaron datos del Global Burden of Disease 2021 para reportar la mortalidad, el impacto en la esperanza de vida y las causas subyacentes entre 2019 y 2021. Se usó una regresión cuadrática para evaluar la mortalidad en exceso como indicador de la respuesta de los estados a la pandemia, considerando su estructura sociodemográfica. RESULTADOS: Entre 2020 y 2021, se registraron 708 971 muertes en exceso, que disminuyeron la esperanza de vida al nacer en 4.6 años; 76 % de esta reducción se atribuyó a COVID-19. La tasa de mortalidad por COVID-19 fue superior a la esperada conforme a las condiciones sociodemográficas de las entidades. CONCLUSIONES: En México y los países de la región, la pandemia fue devastadora y generó regresiones en la esperanza de vida al nacer, que variaron de dos a nueve años. Se requiere más investigación para entender las variaciones en sus efectos.

ABSTRACT

Since 2000, many countries have achieved considerable success in improving child survival, but localized progress remains unclear. To inform efforts towards United Nations Sustainable Development Goal 3.2-to end preventable child deaths by 2030-we need consistently estimated data at the subnational level regarding child mortality rates and trends. Here we quantified, for the period 2000-2017, the subnational variation in mortality rates and number of deaths of neonates, infants and children under 5 years of age within 99 low- and middle-income countries using a geostatistical survival model. We estimated that 32% of children under 5 in these countries lived in districts that had attained rates of 25 or fewer child deaths per 1,000 live births by 2017, and that 58% of child deaths between 2000 and 2017 in these countries could have been averted in the absence of geographical inequality. This study enables the identification of high-mortality clusters, patterns of progress and geographical inequalities to inform appropriate investments and implementations that will help to improve the health of all populations.
