Differences across the lifespan between females and males in the top 20 causes of disease burden globally: a systematic analysis of the Global Burden of Disease Study 2021.

BACKGROUND: Sex and gender shape health. There is a growing body of evidence focused on comprehensively and systematically examining the magnitude, persistence, and nature of differences in health between females and males. Here, we aimed to quantify differences in the leading causes of disease burden between females and males across ages and geographies. METHODS: We used the Global Burden of Disease Study 2021 to compare disability-adjusted life-year (DALY) rates for females and males for the 20 leading causes of disease burden for individuals older than 10 years at the global level and across seven world regions, between 1990 and 2021. We present absolute and relative differences in the cause-specific DALY rates between females and males. FINDINGS: Globally, females had a higher burden of morbidity-driven conditions with the largest differences in DALYs for low back pain (with 478·5 [95% uncertainty interval 346·3-632·8] more DALYs per 100 000 individuals among females than males), depressive disorders (348·3 [241·3-471·0]), and headache disorders (332·9 [48·3-731·9]), whereas males had higher DALY rates for mortality-driven conditions with the largest differences in DALYs for COVID-19 (with 1767·8 [1581·1-1943·5] more DALYs per 100 000 among males than females), road injuries (1012·2 [934·1-1092·9]), and ischaemic heart disease (1611·8 [1405·0-1856·3]). The differences between sexes became larger over age and remained consistent over time for all conditions except HIV/AIDS. The largest difference in HIV/AIDS was observed among those aged 25-49 years in sub-Saharan Africa with 1724·8 (918·8-2613·7) more DALYs per 100 000 among females than males. INTERPRETATION: The notable health differences between females and males point to an urgent need for policies to be based on sex-specific and age-specific data. It is also important to continue promoting gender-sensitive research, and ultimately, implement interventions that not only reduce the burden of disease but also achieve greater health equity.

Health effects associated with exposure to intimate partner violence against women and childhood sexual abuse: a burden of proof study.

The health impacts of intimate partner violence against women and childhood sexual abuse are not fully understood. Here we conducted a systematic review by comprehensively searching seven electronic databases for literature on intimate partner violence-associated and childhood sexual abuse-associated health effects. Following the burden of proof methodology, we evaluated the evidence strength linking intimate partner violence and/or childhood sexual abuse to health outcomes supported by at least three studies. Results indicated a moderate association of intimate partner violence with major depressive disorder and with maternal abortion and miscarriage (63% and 35% increased risk, respectively). HIV/AIDS, anxiety disorders and self-harm exhibited weak associations with intimate partner violence. Fifteen outcomes were evaluated for their relationship to childhood sexual abuse, which was shown to be moderately associated with alcohol use disorders and with self-harm (45% and 35% increased risk, respectively). Associations between childhood sexual abuse and 11 additional health outcomes, such as asthma and type 2 diabetes mellitus, were found to be weak. Although our understanding remains limited by data scarcity, these health impacts are larger in magnitude and more extensive than previously reported. Renewed efforts on violence prevention and evidence-based approaches that promote healing and ensure access to care are necessary.

Resumen Antecedentes: Desde hace treinta años, México ha estudiado la carga de la enfermedad para sustentar decisiones en salud. Objetivo: Analizar la carga de enfermedad, lesiones y factores de riesgo en México entre 1990 y 2021. Material y métodos: Se utilizaron las estimaciones del Global Burden of Disease 2021 para analizar la mortalidad, los años de vida perdidos por muerte prematura, los años vividos con discapacidad y los años de vida saludable perdidos, así como la carga atribuible a los factores de riesgos por sexo, edad y entidad federativa. Resultados: La mortalidad infantil disminuyó 39.4 % de 1990 a 2000, y 49.0 % de 2000 a 2019. En el ámbito nacional, la mortalidad decreció 27.5 % entre 1990 y 2019, pero ascendió en 2020 y 2021 en todos los estados, especialmente en adultos de 35 a 64 años, debido a la pandemia de COVID-19, que contribuyó con 24.3 % de las defunciones en 2019. Se observaron diferencias significativas en la mortalidad según la edad y el sexo. La carga atribuible a los factores de riesgo metabólicos se incrementó, mientras que la atribuible el consumo de alcohol y tabaco disminuyó. El acceso al agua potable y saneamiento mejoró. Conclusiones: Evaluar la carga de enfermedad es crucial para diseñar estrategias eficaces para abordar las necesidades actuales y los futuros desafíos en salud.

Abstract Background: For thirty years, Mexico has studied the burden of disease in order to inform health decisions. Objective: To analyze the burden of disease, injuries, and risk factors in Mexico between 1990 and 2021. Material and methods: Estimates from the Global Burden of Disease 2021 study were used to analyze mortality, years of life lost due to premature mortality, years lived with disability and disability-adjusted life years, as well as the burden attributable to risk factors by sex, age and state of the country. Results: Infant mortality decreased by 39.4% from 1990 to 2000 and by 49.0% from 2000 to 2019. At the national level, mortality decreased by 27.5% between 1990 and 2019, but increased in 2020 and 2021 across all states, especially in adults aged from 35 to 64 years due to the COVID-19 pandemic, which contributed with 24.3% of deaths in 2019. Significant differences in mortality were observed according to age and sex. The burden attributable to metabolic risk factors did increase, while alcohol and tobacco consumption decreased. Access to drinking water and sanitation showed improvements. Conclusions: Assessing the burden of disease is crucial in order to design effective strategies to address current health needs and future healthcare challenges.

Carga atribuible a factores de riesgo en México, 1990-2021. Resumen de los hallazgos del estudio Global Burden of Disease 2021 / The burden attributable to risk factors in Mexico, 1990-2021. Summary of the findings from the Global Burden of Disease 2021 study

Resumen Antecedentes: Durante décadas, México ha transitado de las enfermedades infecciosas a las crónicas y la violencia, debido a cambios en los estilos de vida y la urbanización. Objetivo: Describir el impacto en salud de los factores de riesgo en México entre 1990 y 2021. Material y métodos: Se utilizaron las estimaciones del Global Burden of Disease para analizar la mortalidad y años de vida saludable (AVISA) perdidos atribuibles a factores de riesgo, estratificados por edad, sexo y estado. Resultados: Los factores de riesgo representaron 14.9 millones de AVISA en 2021, 32.4 % del total nacional, con predominio de los riesgos metabólicos (19.8 %). La mortalidad estandarizada por edad debida a estos riesgos se incrementó 6.5 % de 1990 a 2021 y los riesgos conductuales y ambientales se redujeron en más de 50 %. Los factores predominantes cambiaron de desnutrición, problemas de acceso al agua potable y saneamiento en 1990 a altos niveles de glucosa y obesidad en 2021; la desnutrición fue el mayor riesgo en los niños menores de cinco años. Conclusiones: México afronta desafíos sanitarios dobles, la desnutrición infantil continúa y los riesgos metabólicos en adultos se incrementan, sobre todo en los estados menos desarrollados, por lo que se requieren intervenciones específicas para amenazas nuevas y existentes.

Abstract Background: Over the past decades, Mexico's health landscape has shifted from infectious to non-communicable diseases and violence, mirroring lifestyle, urbanization, and developmental changes. Objective: To describe the impact of risk factors on health in Mexico from 1990 to 2021. Material and methods: Using the Global Burden of Diseases, Injuries, and Risk Factors Study estimates, we describe risk factor-related mortality and disability adjusted life years (DALYs) in Mexico (1990-2021) by age, sex, and state of the country. Results: In 2021, risk factors led to 14.9 (12.9-16.7) million DALYs, which accounted for 32.4 % of Mexico's burden. Metabolic risks, with 19.8% (17.0-21.9 %) were the main contributors. From 1990 to 2021, the age-standardized all-cause mortality rate associated with metabolic risks increased by 6.5%, while behavioral and environmental risks decreased by more than 50%, with marked variations between states. The predominant risk factors shifted from malnutrition and unsafe water and sanitation in 1990 to high glucose and body mass index in 2021. Malnutrition-related risks have the highest impact on health loss in children younger than 5 years. Conclusions: Mexico faces a dual health challenge: childhood malnutrition persists, and adult metabolic risks are on the rise, particularly in less developed states, with targeted interventions for traditional and emerging health threats being required.

Enfermedades respiratorias en México. Análisis del estudio Global Burden of Disease 2021 / Respiratory diseases in Mexico. Analysis from the Global Burden of Disease study 2021

Resumen Antecedentes: Las enfermedades respiratorias (ER) se analizan individualmente, posiblemente con subestimación de su carga total. Objetivo: Analizar la carga de las ER en México para población de 20 años o más de 1990 a 2021. Material y métodos: Se presenta la carga de ER en México a partir de estimaciones del estudio Global Burden of Disease en cuanto a mortalidad y años de vida saludable (AVISA) perdidos que comprenden recuentos, tasas por 100 000 y tasas estandarizadas por edad. Las ER se categorizaron en enfermedades respiratorias crónicas (ERC), infecciones respiratorias y cánceres respiratorios. Resultados: En 2021, las ER causaron la muerte de 336 728 adultos mayores de 20 años, lo que representó 30.5 % del total de defunciones, incremento cercano al triple respecto a 2019, principalmente debido a COVID-19. Las ERC contribuyeron con 3.4 % del total de muertes, las infecciones respiratorias con 25.9 % y los cánceres respiratorios con 1.2 %. La mortalidad y AVISA perdidos por ERC se incrementaron persistentemente, con variaciones entre los estados. Las tasas de mortalidad ajustadas por edad de las ERC disminuyeron desde 1990, excepto las enfermedades pulmonares intersticiales, que se incrementaron constantemente. Conclusión: Los significativos niveles de mortalidad y discapacidad debidos a enfermedades respiratorias en México exigen mejorar la prevención, investigación y abordar factores de riesgo como tabaquismo y contaminación, además de fomentar la capacitación médica continua.

Abstract Background: Respiratory diseases (RD) are often analyzed separately rather, possibly leading to an underestimation of their total burden. Objective: To analyze the burden of RD in Mexico for population aged 20 or older from 1990 to 2021. Material y methods: We present the burden of RD in Mexico based on estimates of the Global Burden of Disease study for mortality and disability-adjusted life years (DALYs), comprising counts, rates per 100,000, as well as age-standardized rates. RDs were categorized into three key groups: chronic respiratory diseases (CRD), respiratory infections (RI), and respiratory cancers. Results: In 2021, among those aged 20+, RDs were responsible for 336,728 deaths, which accounts for 30.5% of total deaths— a nearly threefold increase since 2019, primarily due to the COVID-19 pandemic. CRDs contributed with 3.4% of total deaths; RIs, with 25.9%; and respiratory cancers, with 1.2%. CRDs showed a continuous rise in deaths, crude mortality, and DALY rates across genders, with no signs of leveling. RD burden varied widely across states. Age-standardized CRD mortality rates have generally declined since 1990, except for interstitial lung diseases, which have consistently increased. Conclusion: The significant burden of mortality and disability due to RDs in Mexico underscores the necessity for enhanced prevention, research, and for addressing risk factors such as smoking and pollution. Ongoing healthcare training can help reduce RD burden.
