Objective: to assess the efficacy of a Hospital Discharge Transition Plan in the care competence and in adherence to the therapy of dyads comprised by patients with non-communicable chronic diseases and their caregivers. Method: a controlled and randomized clinical trial; the sample was comprised by 80 dyads of patients with chronic conditions and their caregivers, randomly allocated as follows: 40 to the control group and another 40 to the intervention group. The instruments to characterize the patient-caregiver dyad, the patients' and caregivers' care competence and the patients' adherence to the treatment scale were applied. The " CUIDEMOS educational intervention" was applied to the intervention group; in turn, the control group was provided usual care with the aid of a booklet, with phone follow-up via at month 1. Results: 52.5% of the patients and 81.3% of the caregivers were women. The patients' and caregivers' mean ages were 69.5±12.6 and 47.5±13.1 years old, respectively. The Hospital Discharge Transition Plan increased the scores in the "knowledge", "uniqueness", "instrumental", "enjoying", "anticipation" and "social relations" dimensions, as well as the global care competence of the patients and family caregivers; in addition to the following factors: medications, diet, stimulants control, weight control, stress management, and global adherence to the therapy by the patient. There were no statistically significant differences between the control and intervention groups. Conclusion: the Hospital Discharge Transition Plan increased the patients' and family caregivers' care competence after the intervention, as well as the patients' adherence to the treatment. However, there were no differences between the control and intervention groups, possibly due to the similarity of the activities.

Cuantificación de la carga de la enfermedad renal crónica en América Latina: una epidemia invisibilizada / Quantification of the burden of chronic kidney disease in Latin America: an invisible epidemic / Quantificação da carga da doença renal crônica na América Latina: uma epidemia invisível

RESUMEN Objetivo. 1) Describir la carga de la enfermedad renal crónica en países de América Latina entre 1990 y 2019 y, 2) estimar la correlación entre los años de vida saludables perdidos (AVISA) con el índice sociodemográfico y el índice de acceso y calidad de salud. Métodos. Análisis secundario y ecológico, basado en el Estudio de la Carga Global de Enfermedades, Lesiones y Factores de Riesgo 2019. Se reportaron las tasas estandarizadas de mortalidad, años perdidos por muertes prematuras (APMP), años de vida ajustados por discapacidad (AVAD) y AVISA por enfermedad renal crónica para 1990, 2005 y 2019. La información se desagregó por países, sexo, grupos etarios y subcausas. Resultados. Entre 1990 y 2019, la carga de la enfermedad renal crónica aumentó considerablemente en los países de América Latina, convirtiéndose en una de las principales causas de mortalidad y de AVISA. La tasa estandarizada de AVISA por enfermedad renal crónica se debió, en gran medida, al peso de las muertes prematuras más que a la discapacidad. En 2019, Nicaragua, El Salvador, México y Guatemala se destacaron por tener las tasas estandarizadas de mortalidad por enfermedad renal crónica y de AVISA más elevadas, mientras que Uruguay presentó las más bajas. Conclusiones. La enfermedad renal crónica es una epidemia invisibilizada que representa una carga excesiva, en mortalidad y AVISA, para los países de América Latina. Es indispensable aunar esfuerzos regionales para enfrentar la enfermedad, además de impulsar acciones locales que atiendan las particularidades de cada país.

ABSTRACT Objective. 1) Describe the burden of chronic kidney disease in Latin American countries between 1990 and 2019; and 2) Estimate the correlation between disability-adjusted life years (DALYs) and the Sociodemographic Index and the Healthcare Access and Quality Index. Methods. Secondary and ecological analysis, based on the 2019 Global Burden of Diseases, Injuries and Risk Factors Study. Standardized mortality rates, years of life lost to due to premature death (YLLs),years of healthy life lost due to disability (YLDs) and DALYs due to chronic kidney disease were reported for 1990, 2005, and 2019. Information was disaggregated by country, sex, age group, and sub-cause. Results. Between 1990 and 2019, the burden of chronic kidney disease increased considerably in Latin American countries, becoming one of the main causes of mortality and DALYs. The standardized rate of DALYs for chronic kidney disease was largely due to the weight of premature deaths rather than disability. In 2019, Nicaragua, El Salvador, Mexico, and Guatemala had the highest standardized mortality rates for chronic kidney disease and DALYs, while Uruguay had the lowest. Conclusions. Chronic kidney disease is an invisible epidemic that places an excessive burden in terms of mortality and DALYs on Latin American countries. It is essential to join forces to tackle the disease in the region, and promote local actions that address the particularities of each country.

Métodos. Análise secundária e ecológica, baseada no estudo Carga Global de Doenças, Lesões e Fatores de Risco 2019 (GBD). Foram informadas taxas de mortalidade padronizadas, anos de vida perdidos por morte prematura (AVP) por morte prematura, anos de vida ajustados por incapacidade (AVAI) e AVISA devido a doença renal crônica de 1990, 2005 e 2019. Os dados foram desagregados por país, sexo, faixas etárias e causas subjacentes. Resultados. Entre 1990 e 2019, a carga de doença renal crônica aumentou consideravelmente nos países da América Latina, tornando-se uma das principais causas de mortalidade e de AVISA. A taxa padronizada de AVISA devido à doença renal crônica foi influenciada em grande parte pelo peso das mortes prematuras, e não da incapacidade. Em 2019, Nicarágua, El Salvador, México e Guatemala se destacaram por terem as maiores taxas padronizadas de mortalidade por doença renal crônica e AVISA, ao passo que Uruguai teve as menores taxas. Conclusões. A doença renal crônica é uma epidemia invisível, que representa uma carga excessiva em termos de mortalidade e de AVISA para os países da América Latina. É essencial unir esforços na região para combater a doença, além de promover ações locais que atendam às particularidades de cada país.

Caregiver burden, family adaptation, partnership, growth, affection, and resolve, anxiety levels, and perceived social support in relatives of patients with open heart surgery

SUMMARY OBJECTIVE: The aim of this study was to examine the relationship between caregiver burden, family adaptation, partnership, growth, affection, and resolve score, anxiety levels, and the perceived social support of the relatives of patients who had open heart surgery. METHODS: Volunteers among the relatives of patients who had open heart surgery in our cardiovascular surgery clinic and were followed up in the first 3 months were included in the study. The cardiovascular surgeons recorded the sociodemographic data of the relatives of the patients and directed them to a psychiatry clinic for further evaluation. The caregiver burden scale, family adaptation, partnership, growth, affection, and resolve scale, anxiety level scale, and perceived social support scale were applied to the relatives of the patients who participated in the study. RESULTS: Within the scope of the study, a total of 51 individuals, 29.4% (n=15) men and 70.6% (n=36) women, were included in the evaluation. The participants' ages ranged from 32 to 68 years, with an average age of 48 years. There was a statistically significant relationship between the caregiving burden scale score and the scale scores other than age (p<0.05). There was a statistically significant difference in terms of caregiving burden scale score, working status, physical and psychological problems, changes in home life, and changes in family relationships (p<0.05). CONCLUSION: The fact that the need for security and intimacy is related to anxiety and depression can be interpreted as the caregiving problems of the relatives of the patients who think that their patients are safe and feel closer to the intensive care personnel will decrease. Their depression and anxiety levels will also decrease.

Expanding Global Surgery Education in Brazil: Perspectives after the 35th Brazilian Surgical Congress / Expandindo o Ensino de Cirurgia Global no Brasil: Perspectivas após o 35º Congresso Brasileiro de Cirurgia

ABSTRACT The 35th Brazilian Congress of Surgery marked a turning point for surgical education in the country. For the first time, the Brazilian College of Surgeons included Global Surgery on the main congressional agenda, providing a unique opportunity to rethink how surgical skills are taught from a public health perspective. This discussion prompts us to consider why and how Global Surgery education should be expanded in Brazil. Although Brazilian researchers and institutions have contributed to the fields expansion since 2015, Global Surgery education initiatives are still incipient in our country. Relying on successful strategies can be a starting point to promote the area among national surgical practitioners. In this editorial, we discuss potential strategies to expand Global Surgery education opportunities and propose a series of recommendations at the national level.

RESUMO O 35º Congresso Brasileiro de Cirurgia foi marcado por discussões inovadoras para a educação cirúrgica no país. Pela primeira vez, o Colégio Brasileiro de Cirurgiões incluiu a Cirurgia Global na pauta principal do congresso, proporcionando uma oportunidade única de repensar como as habilidades cirúrgicas são ensinadas a partir de uma perspectiva de saúde pública. Essa discussão nos leva a considerar por que e como o ensino da Cirurgia Global deve ser expandido no Brasil. Embora pesquisadores e instituições brasileiras tenham contribuído para a expansão do campo desde 2015, as iniciativas de educação em Cirurgia Global ainda são incipientes em nosso país. Basear-se em estratégias bem-sucedidas pode ser um ponto de partida para promover a área entre os profissionais de cirurgia nacionais. Neste editorial, discutimos potenciais estratégias para expandir as oportunidades de educação em Cirurgia Global e propomos uma série de recomendações a nível nacional.

Burden of coronary heart disease for adult patients and its correlation with sociodemographic index / 公共卫生与预防医学

Objective To analyze the burden of disease attributable to coronary heart disease in adult patients in 2020, to compare the disease burden of patients with coronary heart disease among different sociodemographic indexes (SDI) , and to explore the correlation between the two to provide theoretical guidance for coronary heart disease prevention. Methods The data of 881 adult patients with coronary heart disease in our Hospital in 2020 were collected, and the data, such as illness, morbidity, mortality and disability-adjusted life years (DALY) of adult patients with coronary heart disease were analyzed. Pearson correlation was used to analyze the association between disease burden and sociodemographic index in adult patients with coronary heart disease. Results The prevalence and incidence of adult patients with coronary heart disease were higher in women than in men, while the mortality rate and DALY rate were mainly higher in men than in women. The prevalence, morbidity and mortality rates increased in different age groups, and increased rapidly in the age group of 45 years and beyond. The prevalence of DALY in adult patients with coronary heart disease in different age groups also showed an upward trend, and increased rapidly in the age group of 35 years and beyond. The SDI value of adult patients with coronary heart disease was (0.52±0.16), of which the low SDI value was (0.13±0.05), the medium and low SDI value was (0.34±0.17), the medium SDI value was (0.50±0.14), the medium and high SDI value was (0.82±0.25), and the high SDI value was (0.93±0.13). The chi-square results showed that there were differences in mortality (χ2=12.358, P=0.020) and DALY rate (χ2 =14.557, P=0.011) of adult patients with coronary heart disease between different grades of SDI groups, and the differences were statistically significant. Pearson-related results showed that SDI and DALY rate were negatively correlated in adult patients with coronary heart disease (r=-0.374, P=0.022), and there were gender differences. SDI was negatively correlated with DALY rate in male patients with coronary heart disease (r=-0.489, P=0.017), and SDI was negatively correlated with mortality (r=-0.290, P=0.040) and DALY rate in female patients with coronary heart disease (r=-0.392, P=0.006）. Conclusion Burden of disease attributed to coronary heart disease in adult patients varies by sex and it has a negative correlation with SDI, and the improvement of national welfare and education level, that is, the increase of SDI may have a certain effect on reducing the burden of coronary heart disease.

Disease Burden and Indirect Economic Burden Due to Lung Cancer from 1981 to 2020 in Kunshan, Jiangsu Province, China / 肿瘤防治研究

Objective To identify the disease burden and indirect economic burden caused by lung cancer in Kunshan City, Jiangsu Province, from 1981 to 2020. Methods The incidence and death cases of lung cancer were obtained from cancer registry and death cause monitoring data. The disability adjusted life years (DALY) was used as the evaluation index for burden posed by lung cancer on health, and the indirect economic burden was calculated by a human capital method. Results From 1981 to 2020, a total of 9272 deaths due to lung cancer were reported in Kunshan, of which 7106 were males and 2166 were females. The DALY caused by lung cancer in the whole population were 3.81, 4.14, 4.38, and 9.46 in 1981–1990, 1991–2000, 2001–2010, and 2011–2020, respectively. The indirect economic burden caused by lung cancer was 10.515, 141.657, 813.794, and 6659.149 million yuan. From 2011 to 2020, the ratios of years of life lost due to premature mortality to DALY in males, females, and the general population were 92.42%, 95.15%, and 93.60%, respectively. Conclusion The health burden and indirect economic burden for lung cancer are substantial in the Kunshan City. Moreover, age-specific DALY and indirect economic burden are not exactly symmetrical, suggesting that an effective control strategy to lower cost is urgently needed, especially for individuals aged 40-59.

Trend of Colorectal Cancer Burden in China from 1990 to 2019 / 肿瘤防治研究

Objective To quantitatively analyze the effects of population aging and other risk factors on the burden of colorectal cancer in China from 1990 to 2019. Methods The Global Burden of Disease Study 2019 was used to describe the temporal trend of the burden of colorectal cancer. A decomposition method established by Gupta was applied to quantify the burden related to population growth, aging, age-specific prevalence, and disease severity. Results The age-standardized disability adjusted life years (DALY) rates of colorectal cancer in China showed an overall upward trend from 1990 to 2019. The DALY in 2019 increased by 191.12% compared with that in 1990, with 34.54% of the increase attributed to population growth, 111.36% to population aging, and 77.56% to the rise of age-specific prevalence. Meanwhile, -32.54% benefited from the changes in disease severity. Diet low in milk was the primary risk factor for the disease burden of colorectal cancer in China in 2019, followed by diet low in whole grains and calcium. In the last 30 years, the corresponding risk factor of the most rapid increase in China was high BMI with an average annual percentage of change of 4.14%, and the corresponding risk factor of the most rapid decrease in China was diet low in fiber with an average annual percentage of change of -2.00%. Conclusion Aging population is mainly responsible for the considerable increase in the burden of colorectal cancer in China from 1990 to 2019. The health administrative authorities should take corresponding measures to address the adverse impacts associated with aging.

Correlation between daily exercise load and physical fitness among primary school students / 中国学校卫生

Objective@#To understand the relationship between daily exercise load and physical fitness of primary school students, so as to provide relevant theoretical basis for the development of on campus physical education plans and the improvement of procedural physical health management for elementary school students.@*Methods@#A total of 223 students from 6 classes in a primary school in Beijing were selected by a stratified random cluster sampling method from May to June 2023. The daily exercise load of the students was monitored by Polar Verity Sense heart rate armband. The duration of moderate to vigorous physical activity (MVPA) and daily Training Impulse (TRIMP) value were calculated, and the related indexes of daily exercise load were analyzed. Chi square test and univariate Logistic regression analysis were used to analyze the correlation between daily exercise load and physical fitness assessment levels, and multi factor ordinal Logistic regression analysis was used to explore the influencing factors of physical fitness assessment levels.@*Results@#The average time spent in MVPA was (21.65±17.48) min. The TRIMP value was (361.47±124.81). The time spent in MVPA of primary school students in outdoor class, zero point sports, recess and after class PE were ( 8.86 ±8.56, 9.41±10.47, 1.97±3.12, 2.46±2.57) min, respectively. TRIMP values were (68.89±20.84, 72.83±30.27, 51.68±18.23, 19.99±5.78) in outdoor class, zero point sports, recess and after class PE, respectively. The results of univariate analysis showed that there were statistically significant differences in physical fitness levels among students with different genders, grades, and BMI ( χ 2=7.13, 19.04, 32.98, P <0.05). The duration of daily MVPA, along with TRIMP value during outdoor class, zero point sports, recess, and after PE class were all statistically significant with physical fitness levels ( OR =1.07, 1.05, 1.02, 1.03, 1.11, P <0.05). The results of multi factor ordinal Logistic regression analysis showed that the primary school grade (lower grade: OR =9.24, middle grade: OR =7.81), BMI (abnormal: OR =0.21), duration of daily MVPA in school ( OR =1.06), and TRIMP value during outdoor class ( OR =1.05) were statistically significant with physical fitness levels ( P <0.05).@*Conclusions@#There is a positive correlation between physical fitness and different grades, BMI, daily exercise load, and outdoor exercise load. Increasing daily exercise load can improve students physical health. It is suggested to tailor the school sports program to suit primary school students, increase both the intensity and duration of school daily sports, and promote procedural physical health management for elementary school students.

Objective To retrospectively analyze the epidemiological trend of children with lower gastrointestinal bleeding in recent 10 years,and investigate the change of their disease burden,so as to provide a theoretical basis for the accurate prevention and control of children's lower gastrointestinal bleeding. Methods A total of 671 children with "lower gastrointestinal bleeding" who were diagnosed in our hospital from 2012 to 2021 were collected as research subjects. To analyze the microscopic examination rate and common etiology of lower gastrointestinal bleeding in children in the past 10 years,as well as the epidemiological characteristics of different age groups, different regions and different basic diseases; Calculate and compare the rate of disability life lost (YLD), early death life lost (YLL) and disability adjusted life year (DALY) of children with lower gastrointestinal bleeding within 10 years, and calculate the annual change percentage (AAPC) to analyze the change trend of disease burden. Results The microscopic examination rate of children with lower gastrointestinal bleeding showed a trend of increasing in the past 10 years (P18 years old, hypertension and gastroenteritis. The DALY rate, YLL rate and YLD rate caused by lower gastrointestinal bleeding in the past 10 years showed an upward trend (P<0.05). Conclusion The microscopic examination rate of lower gastrointestinal bleeding in children was graduallyincreasing,and the prevalence rate of basic diseases such as boys,hypertension and gastroenteritis was increasing;in addition,the disease burden caused by children's lower gastrointestinal bleeding was also increasing year by year and should be protected.

Disease burden and mortality forecast of prostate cancer in Wuhan in 2010-2019 / 公共卫生与预防医学

Objective To analyze the data of prostate cancer in Wuhan from 2010 to 2019, understand the characteristics and trends of incidence, mortality, and YLL, and provide decision-making basis for Wuhan's cancer prevention and control strategies. Methods Data on deaths and incident cases of prostate cancer in Wuhan from 2010 to 2019 and from 2013 to 2017, respectively, were collected from the Wuhan Death Monitoring System. Indicators such as incidence rate, mortality rate, and years of life lost due to premature death (YLL) of prostate cancer in Wuhan were calculated using Excel 2016 and Python. The Bayesian Age-Period-Cohort Model (BAPC) was used to predict the mortality rate of prostate cancer in Wuhan from 2020 to 2024. The trend changes were described using the annual average percentage change (AAPC). Results From 2010 to 2019, the incidence, mortality, and YLL rates of prostate cancer in Wuhan showed an overall increasing trend (AAPC >0, P <0.05). The standardized mortality and incidence rates in the central urban area were significantly higher than those in the outer urban area, and the age group of 85 and above had the highest incidence and mortality rates. The age group of 0-54 had the largest increase in incidence and mortality rates. From 2020 to 2024, prostate cancer in Wuhan is expected to continue to increase slightly (an increase of 0.94%). Conclusion The incidence, mortality, and YLL rates of prostate cancer in Wuhan are showing an overall increasing trend, and this trend may continue. The characteristics are higher in the central urban area than in the outer urban area, and higher in the older age group than in the younger age group. Targeted measures need to be taken, and screening for high-risk populations should be strengthened.

Status and trend of refractive disorder burden in China based on a global perspective / 公共卫生与预防医学

Objective Based on the global burden of disease (GBD) study data, to analyze the current situation and changing trend of refractive disorders in China by comparing Japan, India, the United States, the United Kingdom and the world. Methods The prevalence, years lived with disability (YLD) rate of refractive disorders from 1990 to 2019 were obtained from the global health exchange (GHDx）database. The disease burden and change trend of refractive disorders were analyzed using Joinpoint and other software. Results In 2019, the number of refractive disorders in China exceeded 27 million, with the prevalence and YLD rate were 19.18‰ and 89.40/100,000 respectively. From 1990 to 2019, the prevalence and YLD rate of refractive disorders showed an increasing trend globally (except India), with the largest increase in China (up by 53.21% and 53.96% respectively). The age standardized YLD rates in China, Japan, the United States, and the United Kingdom were all lower than the global average level, but China's age standardized YLD rates were higher than the developed countries (Japan, the United States, and the United Kingdom). Conclusion From 1990 to 2019, there was a certain gap between China and developed countries in the control of refractive disorders. Therefore, it is necessary to understand the disease status from a global perspective in order to better prevent and control refractive disorders in the future.

Trends in prevalence and disability-adjusted life years of cataract in China from 1990 to 2019 / 国际眼科杂志(Guoji Yanke Zazhi)

AIM:To assess the evolving burden of cataracts in China from 1990 to 2019.METHODS: Data on disease burden related to cataracts in China were retrieved from the Global Burden of Disease(GBD)2019 study based on large public databases. Utilizing data from the GBD 2019 study, we extracted information on cataract-related disease burden in China from extensive public databases. Analysis of prevalence and disability-adjusted life years(DALYs)associated with cataracts in China was conducted based on GBD 2019 findings. The variable characteristics of age-standardized prevalence rates(ASPR)and age-standardized DALYs rates(ASDR)in China and its neighboring countries were also explored.RESULTS: Between 1990 and 2019, the number of prevalent cases of blindness and vision loss caused by cataracts in China increased by 223.54%, and the corresponding DALYs raised by 142.14%. Over the past 30 years, females exhibited higher age-standardized prevalence and DALYs rates compared to males. Meanwhile, individuals aged 65 to 84 years were found to be more susceptible to cataracts than other age groups. Compared with neighboring countries, China ranked from the 9th position in 1990(867.09, 95%UI: 761.36 to 975.42, per 100 000 population)to the 11th in 2019(991.56, 95%UI: 861.52 to 1131.04, per 100 000 population)in ASPR, while from the 9th in 1990(65.85, 95%UI: 46.39 to 89.41, per 100 000 population)to the 10th position in 2019(59.16, 95%UI: 41.70 to 80.15, per 100 000 population)in ASDR. However, on a global scale, China maintained relatively low ASDR and ASPR for cataracts in 2019.CONCLUSION: The study highlights a substantial rise in the prevalence and DALYs associated with blindness and vision loss due to cataracts from 1990 to 2019 in China, and underscores the urgent need for increased early screening of cataracts, particularly among the elderly and females.

Resumen 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 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. A quadratic regression model was used to evaluate excess mortality as an indicator of the response of the states to the pandemic, considering their sociodemographic structure. 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. Further investigation is required for understanding the variations on its effects.

Epidemia de diabetes tipo 2 en México. Análisis de la carga de la enfermedad 1990-2021 e implicaciones en la política pública / Type 2 diabetes epidemic in Mexico. Burden of disease 1990-2021 analysis and implications for public policies

Resumen Antecedentes: México enfrenta un desafío por la carga que representa la diabetes tipo 2 (DT2). Objetivo: Analizar la epidemiología y la carga de DT2 en México de 1990 a 2021 en los ámbitos nacional y estatal. Material y métodos: Se empleó el Global Burden of Disease 2021 para evaluar prevalencia, incidencia, mortalidad, carga letal y no letal. Se consideraron factores metabólicos, ambientales y de comportamiento. Se realizó análisis comparativo por sexo, edad y entidad federativa. Resultados: Se incrementó la prevalencia de DT2 en 25 % y la incidencia en menores de 45 años; la mortalidad en mujeres disminuyó. La tasa de años de vida saludable (AVISA) perdidos se incrementó en todos los estados, entre 45.2 % en Nuevo León y 237.6 % en Tabasco. En 2021, la DT2 ocasionó 3.1 millones de AVISA perdidos, que representaron 6.6 % de la carga total en México, de la cual 64 % se atribuyó a muertes prematuras. La neuropatía diabética afectó a 47 % y las afecciones visuales a 270 000 personas; 66.3 % de la carga se atribuyó a obesidad. Conclusiones: Urgen políticas integrales para reducir la carga de DT2 en México, mediante pautas estandarizadas, estrategias basadas en evidencia y recursos tecnológicos que mejoren la accesibilidad y eficiencia de la atención médica.

Abstract Background: Mexico faces a challenge due to the burden imposed by type 2 diabetes (T2D). Objective: To analyze T2D epidemiology and burden in Mexico from 1990 to 2021, at the national and state levels. Material and methods: Estimates from the Global Burden of Disease 2021 study were used to evaluate the prevalence, incidence, mortality, fatal and non-fatal burden. Metabolic, environmental and behavioral factors were considered. Comparative analyses were carried out by gender, age and state of the country. Results: The prevalence of T2D increased by 25%. The incidence increased in those younger than 45 years, with a mortality decrease being found among women. The rate of disability-adjusted life years (DALY) showed an increase in all states, from 45.2% in Nuevo León to 237.6% in Tabasco. In 2021, T2D caused the loss of 3.1 million DALYs, which accounted for 6.6% of total burden in Mexico, out of which 64% was due to premature deaths. Diabetic neuropathy affected 47%, and there were 270,000 cases of visual impairment; 66.3% of the burden was attributed to obesity. Conclusions: Comprehensive policies are urgently needed in order to reduce the burden of T2D in Mexico, through standardized guidelines, evidence-based strategies and technological resources that improve medical care accessibility and efficiency.

La carga de enfermedad renal crónica en México. Análisis de datos basado en el estudio Global Burden of Disease 2021 / The burden of chronic kidney disease in Mexico. Data analysis based on the Global Burden of Disease 2021 study

Resumen Antecedentes: La enfermedad renal crónica (ERC) representa una elevada carga global de enfermedad debido a la falta de pruebas universales y a la interpretación errónea de biomarcadores. Objetivo: Analizar la epidemiología de la ERC en México y orientar las políticas públicas. Material y métodos: Se utilizaron los datos del estudio Global Burden of Disease (GBD) 2021 para describir la prevalencia y mortalidad de la ERC en México durante el periodo de 1990 a 2021, estratificando por sexo y grupos de edad. Resultados: La prevalencia de la ERC en México en 2021 fue de 9184.9 por 100 000 habitantes. La diabetes constituyó la causa más común de ERC y la mortalidad por ERC fue elevada, se incrementó en 2019 y 2021, posiblemente debido a la pandemia de COVID-19. Conclusiones: La ERC en México presenta una alta carga de mortalidad y años de vida perdidos, pero contribuye poco a la discapacidad. Es esencial mejorar la detección temprana de la ERC, el acceso a tratamientos y la codificación de las causas de la enfermedad. Además, investigar las causas de la ERC de etiología desconocida, incluidos factores genéticos, es crucial para desarrollar tratamientos específicos en el futuro.

Abstract Background: Chronic kidney disease (CKD) represents a substantial global burden of disease due to a lack of universal tests and misinterpretation of biomarkers. Objective: To analyze CKD epidemiology in Mexico and guide public policies. Material and methods: Data from the Global Burden of Disease (GBD) 2021 study were used to describe CKD prevalence and mortality in Mexico for the 1990-2021 period, stratifying by gender and age groups. Results: The prevalence of CKD in Mexico in 2021 was 9,184.9 per 100,000 population. Diabetes was the most common cause of CKD, and CKD-related mortality was high, with an increase in 2019 and 2021, possibly as a consequence of the COVID-19 pandemic. Conclusions: CKD in Mexico entails a high burden of mortality and years of life lost, but it barely contributes to disability. It is essential to improve CKD early detection, access to treatments and coding of the causes of the disease. Moreover, investigating the causes of CKD of unknown etiology, including genetic factors, is crucial in order for specific treatments to be developed in the future.

La carga de la enfermedad por cirrosis hepática en México / Burden of disease due to liver cirrhosis in Mexico

Resumen Antecedentes: La cirrosis hepática es una causa importante de morbilidad y mortalidad en el mundo. En México, constituye una las primeras seis causas de muerte. Objetivo: Analizar los datos epidemiológicos derivados del estudio de Global Burden of Disease y su relación con los factores de riesgo asociados al desarrollo de hepatopatías crónicas en México. Material y métodos: Se realizó el análisis de datos provenientes del Instituto para la Medición y Evaluación de la Salud y del Instituto Nacional de Estadística y Geografía. Resultados: La cirrosis hepática tiene una prevalencia alta en México, con una carga de enfermedad importante traducida en años perdidos de vida saludable, por muerte prematura y por discapacidad. La mortalidad por cirrosis ocupó el sexto lugar (3.6 %) en 2021 y fue la octava causa de años de vida saludable perdidos (2.8 %). De 1990 a 2021, la tasa de mortalidad se incrementó de 26.7 a 34.2 por 100 000 habitantes. Conclusiones: La carga de enfermedad por cirrosis hepática se continúa derivando del consumo de alcohol y de la hepatitis C; la prevalencia de la cirrosis causada por enfermedad hepática esteatósica se ha incrementado en la última década. Existen cambios epidemiológicos en la frecuencia y carga de la hepatopatía crónica que muestra variaciones territoriales en México.

Abstract Background: Liver cirrhosis is a major cause of morbidity and mortality worldwide. In Mexico, it is one of the six leading causes of death. Objective: To analyze epidemiological data derived from the Global Burden of Disease study and their relationship with risk factors associated with the development of chronic liver diseases in Mexico. Material and methods: An analysis of data from the Institute for Health Metrics and Evaluation and the National Institute of Geography and Statistics was carried out. Results: Liver cirrhosis has a high prevalence in Mexico, with significant burden of disease translating into lost years of healthy life, premature death and disability. Mortality due to cirrhosis ranked sixth (3.6%) in 2021 and was the eighth cause of years of healthy life lost (2.8%). From 1990 to 2021, the mortality rate increased from 26.7 to 34.2 per 100,000 population. Conclusions: The burden of disease due to liver cirrhosis continues to be caused by alcohol consumption and hepatitis C; cirrhosis caused by steatotic liver disease has increased in terms of prevalence over the past decade. There are epidemiological changes in the frequency and burden of chronic liver disease that show territorial variations in Mexico.

Los trastornos mentales en México 1990-2021. Resultados del estudio Global Burden of Disease 2021 / Mental disorders in Mexico 1990-2021. Results from the Global Burden of Disease 2021 study

Resumen Antecedentes: Los trastornos mentales constituyen una de las principales causas de años vividos con discapacidad, si bien no se dispone de estimaciones recientes sobre su magnitud. Objetivo: Reportar las tendencias de prevalencia de trastornos mentales, los años vividos con discapacidad y los años de vida saludables perdidos por sexo, edad y entidad federativa de México. Material y métodos: Se utilizó la base de datos para México del Global Burden of Disease. Resultados: Se calcularon 18.1 millones de personas con algún trastorno mental en 2021, que representaron un incremento de 15.4 % respecto a 2019. Los trastornos depresivos y de ansiedad aumentaron de manera notable entre 2019 y 2021, lo cual posiblemente esté relacionado con COVID-19, el confinamiento y los duelos vividos durante la pandemia. Conclusiones: Los trastornos mentales se han incrementado considerablemente desde la única encuesta nacional de salud mental que utilizó criterios diagnósticos para evaluar las prevalencias. Es importante invertir en estudios epidemiológicos, prevención y atención de los trastornos mentales, los cuales se encuentran entre las primeras causas de años vividos con discapacidad en el país.

Abstract Background: Mental disorders are one of the main causes of years lived with disability, although there is a lack of recent estimates of their magnitude. Objective: To report the trends of mental disorders prevalence, years lived with disability and years of healthy life lost by sex, age and state in Mexico. Material and methods: The Global Burden of Disease database for Mexico was used. Results: There were an estimated 18.1 million persons with some mental disorder in 2021, which represented an increase of 15.4% in comparison with 2019. Depressive and anxiety disorders did significantly increase between 2019 and 2021, which is possibly related to COVID-19, the confinement and the situations of grief experienced during the pandemic. Conclusions: Mental disorders have considerably increased since the only national mental health survey that used diagnostic criteria to evaluate their prevalence. It is important to invest in epidemiological studies, prevention and care of mental disorders, which are among the leading causes of years lived with disability in the country.

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.

Análisis de la carga de enfermedad atribuible a los factores de riesgo ambientales en México en el período 1990-2021. Identificación de avances, rezagos y emergencias / Analysis of the burden of disease attributable to environmental risk factors in Mexico in the 1990-2021 period. Identification of advances, lags and emergencies

Resumen Antecedentes: Se estima que los factores de riesgo ambientales (FRA) fueron responsables en 2019 de nueve millones de muertes en el mundo. Objetivo: A partir de datos del estudio Global Burden of Disease, se analizaron indicadores de pérdida de salud asociada a la exposición a FRA en México. Material y métodos: Se analizaron números absolutos y porcentajes poblacionales de muertes y años de vida saludable (AVISA) perdidos según sexo atribuidos a FRA seleccionados en los ámbitos nacional y estatal, así como las tendencias estandarizadas por edad de 1990 a 2021. Resultados: En 2021, la contaminación por material particulado en ambiente exterior mostró la mayor mortalidad y AVISA perdidos por los FRA seleccionados (42.2 y 38.1 %, respectivamente), seguida de la exposición a plomo (20.6 y 13.4 %) y temperatura baja (19.8 y 12.3 %). Ambos indicadores han disminuido en todos los FRA seleccionados, en magnitudes diferentes entre 1991 y 2021, excepto la temperatura alta. Conclusiones: A pesar de las disminuciones en los últimos 32 años, el material particulado en ambiente exterior mostró la mayor mortalidad y AVISA perdidos, seguido de la exposición a plomo. Es fundamental fortalecer las políticas de calidad del aire y exposición a plomo en México.

Abstract Background: It is estimated that environmental risk factors (ERF) were responsible for nine million deaths worldwide in 2019. Objective: Using data from the Global Burden of Disease study, indicators of health loss associated with exposure to ERF in Mexico were analyzed. Material and methods: Absolute numbers and population percentages of deaths and disability-adjusted life years (DALY) lost attributed to selected ERFs were analyzed at the national and state level and by sex, as well as age-standardized trends from 1990 to 2021. Results: In 2021, ambient particulate matter pollution showed the highest mortality and DALYs lost attributed to selected ERFs (42.2 and 38.1% respectively), followed by lead exposure (20.6 and 13.4%) and low temperature (19.8 and 12.3%). Both indicators have decreased for all selected ERAs by different magnitudes between 1991 and 2021, except for high temperature. Conclusions: Despite decreases in the last 32 years, outdoor environment particulate matter showed the highest mortality and DALYs lost, followed by lead exposure. It is essential to strengthen air quality and lead exposure policies in Mexico.
