Estimating mortality and disability in Peru before the COVID-19 pandemic: a systematic analysis from the Global Burden of the Disease Study 2019.

Background: Estimating and analyzing trends and patterns of health loss are essential to promote efficient resource allocation and improve Peru's healthcare system performance. Methods: Using estimates from the Global Burden of Disease (GBD), Injuries, and Risk Factors Study (2019), we assessed mortality and disability in Peru from 1990 to 2019. We report demographic and epidemiologic trends in terms of population, life expectancy at birth (LE), mortality, incidence, prevalence, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs) caused by the major diseases and risk factors in Peru. Finally, we compared Peru with 16 countries in the Latin American (LA) region. Results: The Peruvian population reached 33.9 million inhabitants (49.9% women) in 2019. From 1990 to 2019, LE at birth increased from 69.2 (95% uncertainty interval 67.8-70.3) to 80.3 (77.2-83.2) years. This increase was driven by the decline in under-5 mortality (-80.7%) and mortality from infectious diseases in older age groups (+60 years old). The number of DALYs in 1990 was 9.2 million (8.5-10.1) and reached 7.5 million (6.1-9.0) in 2019. The proportion of DALYs due to non-communicable diseases (NCDs) increased from 38.2% in 1990 to 67.9% in 2019. The all-ages and age-standardized DALYs rates and YLLs rates decreased, but YLDs rates remained constant. In 2019, the leading causes of DALYs were neonatal disorders, lower respiratory infections (LRIs), ischemic heart disease, road injuries, and low back pain. The leading risk factors associated with DALYs in 2019 were undernutrition, high body mass index, high fasting plasma glucose, and air pollution. Before the COVID-19 pandemic, Peru experienced one of the highest LRIs-DALYs rates in the LA region. Conclusion: In the last three decades, Peru experienced significant improvements in LE and child survival and an increase in the burden of NCDs and associated disability. The Peruvian healthcare system must be redesigned to respond to this epidemiological transition. The new design should aim to reduce premature deaths and maintain healthy longevity, focusing on effective coverage and treatment of NCDs and reducing and managing the related disability.

Unveiling the Burden of Miscoding and Misclassification in Stroke Mortality: Analysis of Multiple Cause-of-Death Data in Mexico.

BACKGROUND: The prevalence of risk factors for cerebrovascular diseases in Mexico is increasing although stroke mortality declined from 1990 to 2010, without meaningful changes afterward. While improving access to adequate prevention and care could explain this trend, miscoding and misclassification in death certificates need to be assessed to unveil the true burden of stroke in Mexico. Practices in death certification along with the presence of multi-morbidity could contribute to this distortion. Analyses of multiple causes of death could reveal ill-defined stroke deaths, providing a glimpse of this bias. METHODS: Cause-of-death information from 4,262,666 death certificates in Mexico from 2009 to 2015, was examined to determine the extent of miscoding and misclassification on the true burden of stroke. Age-standardized mortality rates per 100,000 inhabitants (ASMR) were calculated for stroke as underlying and multiple causes of death, by sex and state. Deaths were classified following international standards as ischemic stroke, intracerebral hemorrhage, subarachnoid hemorrhage, and unspecified, which were kept as an independent category to measure miscoding. To approximate misclassification, we compared ASMR under three misclassification scenarios: (1) current (the status quo); (2) moderate, which includes deaths from selected causes mentioning stroke; and (3) high which includes all deaths mentioning stroke. National and subnational data were analyzed to search for geographical patterns. RESULTS: The burden of stroke in Mexico is underreported due to miscoding and misclassification. Miscoding is an important issue since almost 60% of all stroke deaths are registered as unspecified. Multiple cause analysis indicates that stroke ASMR could increase 39.9%-52.9% of the current ASMR under moderate and high misclassification scenarios, respectively. Both problems indicate the need to improve death codification procedures and cause-of-death classification. CONCLUSIONS: Miscoding and misclassification lead to underestimation of the burden of stroke in Mexico. Stroke deaths are underreported when other important causes coexist, being diabetes the most frequent.

Trends in the burden of stroke in Mexico: A national and subnational analysis of the global burden of disease 1990-2019.

Background: Scarce epidemiological information on stroke in Mexico impedes evidence-based decisions and debilitates the design of effective prevention programmes at the local level. Methods: Ecological and secondary analysis of Global Burden of Disease national and subnational data for Mexico, from 1990 to 2019. We analysed the incidence, prevalence, deaths, premature mortality, disability, and DALYs due to cerebrovascular disease included to identify the differences in the burden of stroke in Mexico by type of stroke (ischaemic [IS], intracerebral haemorrhage [ICH] and subarachnoid haemorrhage [SAH]), sex, age groups, and state levels ordered by quartiles of Sociodemographic Index (SDI). Means and 95% uncertainty intervals are reported. Findings: Reductions in all metrics of total stroke occurred during the 1990 to 2005 period; however, this declining trend was followed up by stagnation of progress from 2006 to 2019, except for premature mortality. This pattern of the declining trend was observed also for IS and to a lesser extent for ICH, while SAH showed no major changes during the 1990-2019 period. The magnitude of decline was higher in females for total stroke for incidence, prevalence and YLDs rates. The less developed states by SDI exhibited the lowest improvements during the period, particularly for ICH metrics. Interpretation: The reduction in stroke burden in Mexico did not follow the same pace for all types of stroke, with regional differences by SDI and by sex. Study findings reveal the need for strengthening prevention policies to address health disparities in the burden of stroke by sex and states, within the fragmented Mexican Healthcare System.

Abstract: Objective: To estimate the cost of common versus normative practice in the treatment of breast cancer (BrCa) at the Mexican Institute of Social Security and Services for Government Workers (ISSSTE). Materials and methods: A process approach from the perspective of providers. We identified the resources utilized during one year of treatment through online questionnaires administered to oncologists in various hospitals (common treatment) as well as by conducting a clinical guidelines review (normative treatment). Results: The cost of common treatment was USD113.6 million annually. For stage I cases, it proved 1.23 and 1.12 times higher in regional and general as opposed to highly specialized hospitals. For stages 0-II cases, it was higher than normative treatment owing to greater use of consultations and chemotherapy. Conclusions: BrCa accounts for 3.8% of the ISSSTE budget in 2017. Achieving greater efficiency in the use of resources allocated for BrCa treatment requires stricter adherence to clinical guidelines as well as early detection.

Government Expenditure on Maternal Health and Family Planning Services for Adolescents in Mexico, 2003-2015.

The purpose of this study was to assess whether government policies to expand the coverage of maternal health and family planning (MHFP) services were benefiting the adolescents in need. To this end, we estimated government MHFP expenditure for 10- to 19-year-old adolescents without social security (SS) coverage between 2003 and 2015. We evaluated its evolution and distribution nationally and sub-nationally by level of marginalization, as well as its relationship with demand indicators. Using Jointpoint regressions, we estimated the average annual percent change (AAPC) nationally and among states. Expenditure for adolescents without SS coverage registered 15% for AAPC for the period 2003-2011 and was stable for the remaining years, with 88% of spending allocated to maternal health. Growth in MHFP expenditure reduced the ratio of spending by 13% among groups of states with greater/lesser marginalization; nonetheless, the poorest states continued to show the lowest levels of expenditure. Although adolescents without SS coverage benefited from greater MHFP expenditure as a consequence of health policies directed at achieving universal health coverage, gaps persisted in its distribution among states, since those with similar demand indicators exhibited different levels of expenditure. Further actions are required to improve resource allocation to disadvantaged states and to reinforce the use of FP services by adolescents.

Unintentional injuries in Mexico, 1990-2017: findings from the Global Burden of Disease Study 2017.

BACKGROUND: To date, the burden of injury in Mexico has not been comprehensively assessed using recent advances in population health research, including those in the Global Burden of Disease Study 2017 (GBD 2017). METHODS: We used GBD 2017 for burden of unintentional injury estimates, including transport injuries, for Mexico and each state in Mexico from 1990 to 2017. We examined subnational variation, age patterns, sex differences and time trends for all injury burden metrics. RESULTS: Unintentional injury deaths in Mexico decreased from 45 363 deaths (44 662 to 46 038) in 1990 to 42 702 (41 439 to 43 745) in 2017, while age-standardised mortality rates decreased from 65.2 (64.4 to 66.1) in 1990 to 35.1 (34.1 to 36.0) per 100 000 in 2017. In terms of non-fatal outcomes, there were 3 120 211 (2 879 993 to 3 377 945) new injury cases in 1990, which increased to 5 234 214 (4 812 615 to 5 701 669) new cases of injury in 2017. We estimated 2 761 957 (2 676 267 to 2 859 777) disability-adjusted life years (DALYs) due to injuries in Mexico in 1990 compared with 2 376 952 (2 224 588 to 2 551 004) DALYs in 2017. We found subnational variation in health loss across Mexico's states, including concentrated burden in Tabasco, Chihuahua and Zacatecas. CONCLUSIONS: In Mexico, from 1990 to 2017, mortality due to unintentional injuries has decreased, while non-fatal incident cases have increased. However, unintentional injuries continue to cause considerable mortality and morbidity, with patterns that vary by state, age, sex and year. Future research should focus on targeted interventions to decrease injury burden in high-risk populations.

Overview of the burden of chronic kidney disease in Mexico: secondary data analysis based on the Global Burden of Disease Study 2017.

OBJECTIVE: To describe the evolution of the burden of chronic kidney disease (CKD) in Mexico by states, sex and subtypes from 1990 to 2017. DESIGN: Secondary data analysis based on the Global Burden of Disease Study (GBD) 2017. PARTICIPANTS: Mexico and its 32 states. Data were publicly available and de-identified and individuals were not involved. METHODS: We analysed age-standardised mortality rates, years of life lost (YLL) due to premature death, years lived with disability (YLD) and disability-adjusted life years (DALY), as well as the percentage of change of these indicators between 1990 and 2017. RESULTS: From 1990 to 2017, the number of deaths, YLL, YLD and DALY due to CKD increased from 12 395 to 65 033, from 330 717 to 1 544 212, from 86 416 to 210 924 and from 417 133 to 1 755 136, respectively. Age-standardised rates went from 28.7 to 58.1 for deaths (% of change 102.3), from 601.2 to 1296.7 for YLL (% of change 115.7), from 158.3 to 175.4 for YLD (% of change 10.9) and from 759.4 to 1472.2 for DALY (% of change 93.8). The highest burden of CKD was for Puebla and the lowest for Sinaloa. It was also greater for men than women. By subtypes of CKD, diabetes and hypertension were the causes that contributed most to the loss of years of healthy life in the Mexican population. CONCLUSIONS: Mexico has experienced exponential and unprecedented growth in the burden of CKD with significant differences by states, sex and subtypes. Data from the GBD are key inputs to guide decision-making and focus efforts towards the reduction of inequities in CKD. These results should be considered a valuable resource that can help guide the epidemiological monitoring of this disease and prioritise the most appropriate health interventions.

Diseases, Injuries, and Risk Factors in Child and Adolescent Health, 1990 to 2017: Findings From the Global Burden of Diseases, Injuries, and Risk Factors 2017 Study.

Importance: Understanding causes and correlates of health loss among children and adolescents can identify areas of success, stagnation, and emerging threats and thereby facilitate effective improvement strategies. Objective: To estimate mortality and morbidity in children and adolescents from 1990 to 2017 by age and sex in 195 countries and territories. Design, Setting, and Participants: This study examined levels, trends, and spatiotemporal patterns of cause-specific mortality and nonfatal health outcomes using standardized approaches to data processing and statistical analysis. It also describes epidemiologic transitions by evaluating historical associations between disease indicators and the Socio-Demographic Index (SDI), a composite indicator of income, educational attainment, and fertility. Data collected from 1990 to 2017 on children and adolescents from birth through 19 years of age in 195 countries and territories were assessed. Data analysis occurred from January 2018 to August 2018. Exposures: Being under the age of 20 years between 1990 and 2017. Main Outcomes and Measures: Death and disability. All-cause and cause-specific deaths, disability-adjusted life years, years of life lost, and years of life lived with disability. Results: Child and adolescent deaths decreased 51.7% from 13.77 million (95% uncertainty interval [UI], 13.60-13.93 million) in 1990 to 6.64 million (95% UI, 6.44-6.87 million) in 2017, but in 2017, aggregate disability increased 4.7% to a total of 145 million (95% UI, 107-190 million) years lived with disability globally. Progress was uneven, and inequity increased, with low-SDI and low-middle-SDI locations experiencing 82.2% (95% UI, 81.6%-82.9%) of deaths, up from 70.9% (95% UI, 70.4%-71.4%) in 1990. The leading disaggregated causes of disability-adjusted life years in 2017 in the low-SDI quintile were neonatal disorders, lower respiratory infections, diarrhea, malaria, and congenital birth defects, whereas neonatal disorders, congenital birth defects, headache, dermatitis, and anxiety were highest-ranked in the high-SDI quintile. Conclusions and Relevance: Mortality reductions over this 27-year period mean that children are more likely than ever to reach their 20th birthdays. The concomitant expansion of nonfatal health loss and epidemiological transition in children and adolescents, especially in low-SDI and middle-SDI countries, has the potential to increase already overburdened health systems, will affect the human capital potential of societies, and may influence the trajectory of socioeconomic development. Continued monitoring of child and adolescent health loss is crucial to sustain the progress of the past 27 years.

Global, Regional, and National Cancer Incidence, Mortality, Years of Life Lost, Years Lived With Disability, and Disability-Adjusted Life-Years for 29 Cancer Groups, 1990 to 2016: A Systematic Analysis for the Global Burden of Disease Study.

Importance: The increasing burden due to cancer and other noncommunicable diseases poses a threat to human development, which has resulted in global political commitments reflected in the Sustainable Development Goals as well as the World Health Organization (WHO) Global Action Plan on Non-Communicable Diseases. To determine if these commitments have resulted in improved cancer control, quantitative assessments of the cancer burden are required. Objective: To assess the burden for 29 cancer groups over time to provide a framework for policy discussion, resource allocation, and research focus. Evidence Review: Cancer incidence, mortality, years lived with disability, years of life lost, and disability-adjusted life-years (DALYs) were evaluated for 195 countries and territories by age and sex using the Global Burden of Disease study estimation methods. Levels and trends were analyzed over time, as well as by the Sociodemographic Index (SDI). Changes in incident cases were categorized by changes due to epidemiological vs demographic transition. Findings: In 2016, there were 17.2 million cancer cases worldwide and 8.9 million deaths. Cancer cases increased by 28% between 2006 and 2016. The smallest increase was seen in high SDI countries. Globally, population aging contributed 17%; population growth, 12%; and changes in age-specific rates, -1% to this change. The most common incident cancer globally for men was prostate cancer (1.4 million cases). The leading cause of cancer deaths and DALYs was tracheal, bronchus, and lung cancer (1.2 million deaths and 25.4 million DALYs). For women, the most common incident cancer and the leading cause of cancer deaths and DALYs was breast cancer (1.7 million incident cases, 535 000 deaths, and 14.9 million DALYs). In 2016, cancer caused 213.2 million DALYs globally for both sexes combined. Between 2006 and 2016, the average annual age-standardized incidence rates for all cancers combined increased in 130 of 195 countries or territories, and the average annual age-standardized death rates decreased within that timeframe in 143 of 195 countries or territories. Conclusions and Relevance: Large disparities exist between countries in cancer incidence, deaths, and associated disability. Scaling up cancer prevention and ensuring universal access to cancer care are required for health equity and to fulfill the global commitments for noncommunicable disease and cancer control.

[Effective coverage of treatment of hypertension in Mexican adults by states]. / Cobertura efectiva del tratamiento de la hipertensión arterial en adultos en México por entidad federativa.

OBJECTIVE:: To estimate the effective coverage (EC) of treatment of hypertension (HT) in Mexican adults in 2012 and compared with those reported in 2006. MATERIALS AND METHODS:: The National Health and Nutrition Survey 2012 was analyzed. The EC has three dimensions: health need as prevalence of HT, utilization of health services when the need is real and quality as recovering health after the treatment. The EC of treatment of HT was estimated using instrumental variables. RESULTS:: In 2012, the EC national of treatment of HT was 28.3% (95%CI 26.5-30.1), ranging from Michoacan with 19.3% (15.3-23.4) to State of Mexico with 39.7% in (25.3-54.0). From 2006 to 2012 the national EC increased 22.5%. CONCLUSION:: The EC treatment of hypertension is low and heterogeneous. The use of synthetic indicators should be a daily exercise of measurement, because report summarizes the performance of state health systems.

Dissonant health transition in the states of Mexico, 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013.

BACKGROUND: Child and maternal health outcomes have notably improved in Mexico since 1990, whereas rising adult mortality rates defy traditional epidemiological transition models in which decreased death rates occur across all ages. These trends suggest Mexico is experiencing a more complex, dissonant health transition than historically observed. Enduring inequalities between states further emphasise the need for more detailed health assessments over time. The Global Burden of Diseases, Injuries, and Risk Factors Study 2013 (GBD 2013) provides the comprehensive, comparable framework through which such national and subnational analyses can occur. This study offers a state-level quantification of disease burden and risk factor attribution in Mexico for the first time. METHODS: We extracted data from GBD 2013 to assess mortality, causes of death, years of life lost (YLLs), years lived with disability (YLDs), disability-adjusted life-years (DALYs), and healthy life expectancy (HALE) in Mexico and its 32 states, along with eight comparator countries in the Americas. States were grouped by Marginalisation Index scores to compare subnational burden along a socioeconomic dimension. We split extracted data by state and applied GBD methods to generate estimates of burden, and attributable burden due to behavioural, metabolic, and environmental or occupational risks. We present results for 306 causes, 2337 sequelae, and 79 risk factors. FINDINGS: From 1990 to 2013, life expectancy from birth in Mexico increased by 3·4 years (95% uncertainty interval 3·1-3·8), from 72·1 years (71·8-72·3) to 75·5 years (75·3-75·7), and these gains were more pronounced in states with high marginalisation. Nationally, age-standardised death rates fell 13·3% (11·9-14·6%) since 1990, but state-level reductions for all-cause mortality varied and gaps between life expectancy and years lived in full health, as measured by HALE, widened in several states. Progress in women's life expectancy exceeded that of men, in whom negligible improvements were observed since 2000. For many states, this trend corresponded with rising YLL rates from interpersonal violence and chronic kidney disease. Nationally, age-standardised YLL rates for diarrhoeal diseases and protein-energy malnutrition markedly decreased, ranking Mexico well above comparator countries. However, amid Mexico's progress against communicable diseases, chronic kidney disease burden rapidly climbed, with age-standardised YLL and DALY rates increasing more than 130% by 2013. For women, DALY rates from breast cancer also increased since 1990, rising 12·1% (4·6-23·1%). In 2013, the leading five causes of DALYs were diabetes, ischaemic heart disease, chronic kidney disease, low back and neck pain, and depressive disorders; the latter three were not among the leading five causes in 1990, further underscoring Mexico's rapid epidemiological transition. Leading risk factors for disease burden in 1990, such as undernutrition, were replaced by high fasting plasma glucose and high body-mass index by 2013. Attributable burden due to dietary risks also increased, accounting for more than 10% of DALYs in 2013. INTERPRETATION: Mexico achieved sizeable reductions in burden due to several causes, such as diarrhoeal diseases, and risks factors, such as undernutrition and poor sanitation, which were mainly associated with maternal and child health interventions. Yet rising adult mortality rates from chronic kidney disease, diabetes, cirrhosis, and, since 2000, interpersonal violence drove deteriorating health outcomes, particularly in men. Although state inequalities from communicable diseases narrowed over time, non-communicable diseases and injury burdens varied markedly at local levels. The dissonance with which Mexico and its 32 states are experiencing epidemiological transitions might strain health-system responsiveness and performance, which stresses the importance of timely, evidence-informed health policies and programmes linked to the health needs of each state.

The burden of cancer in Mexico, 1990-2013.

OBJECTIVE: To analyze mortality and incidence for 28 cancers by deprivation status, age and sex from 1990 to 2013. MATERIALS AND METHODS: The data and methodological approaches provided by the Global Burden of Disease (GBD 2013) were used. RESULTS: Trends from 1990 to 2013 show important changes in cancer epidemiology in Mexico. While some cancers show a decreasing trend in incidence and mortality (lung, cervical) others emerge as relevant health priorities (prostate, breast, stomach, colorectal and liver cancer). Age standardized incidence and mortality rates for all cancers are higher in the northern states while the central states show a decreasing trend in the mortality rate. The analysis show that infection related cancers like cervical or liver cancer play a bigger role in more deprived states and that cancers with risk factors related to lifestyle like colorectal cancer are more common in less marginalized states. CONCLUSIONS: The burden of cancer in Mexico shows complex regional patterns by age, sex, types of cancer and deprivation status. Creation of a national cancer registry is crucial.

Resumen: Objetivo: Analizar la incidencia y la mortalidad de 28 tipos de cáncer por nivel de marginación, grupos de edad y sexo, de 1990 a 2013. Material y métodos: Los datos utilizados provienen del estudio de la Carga Global de Enfermedades (2013). Las entidades federativas se clasificaron de acuerdo con el índice de marginación del Consejo Nacional de Población. Resultados: Los datos muestran una tendencia decreciente para algunos cánceres (pulmón y cervical), mientras otros aparecen como prioritarios y relevantes (próstata, mama, estómago, colon e hígado). En el norte se observan incrementos regionales mayores en las tasas de incidencia y mortalidad estandarizadas por edad, mientras que en los estados del centro se observa una tendencia decreciente de la tasa de mortalidad. Conclusiones: La epidemiología del cáncer en México (en su mayoría basada en datos de mortalidad) presentan patrones regionales complejos por edad, sexo, tipo de cáncer e índice de marginación. Es vital la creación de un registro nacional para mejorar el seguimiento y evaluación de intervenciones preventivas y curativas.

Financing Maternal Health and Family Planning: Are We on the Right Track? Evidence from the Reproductive Health Subaccounts in Mexico, 2003-2012.

OBJECTIVE: To analyze whether the changes observed in the level and distribution of resources for maternal health and family planning (MHFP) programs from 2003 to 2012 were consistent with the financial goals of the related policies. MATERIALS AND METHODS: A longitudinal descriptive analysis of the Mexican Reproductive Health Subaccounts 2003-2012 was performed by financing scheme and health function. Financing schemes included social security, government schemes, household out-of-pocket (OOP) payments, and private insurance plans. Functions were preventive care, including family planning, antenatal and puerperium health services, normal and cesarean deliveries, and treatment of complications. Changes in the financial imbalance indicators covered by MHFP policy were tracked: (a) public and OOP expenditures as percentages of total MHFP spending; (b) public expenditure per woman of reproductive age (WoRA, 15-49 years) by financing scheme; (c) public expenditure on treating complications as a percentage of preventive care; and (d) public expenditure on WoRA at state level. Statistical analyses of trends and distributions were performed. RESULTS: Public expenditure on government schemes grew by approximately 300%, and the financial imbalance between populations covered by social security and government schemes decreased. The financial burden on households declined, particularly among households without social security. Expenditure on preventive care grew by 16%, narrowing the financing gap between treatment of complications and preventive care. Finally, public expenditure per WoRA for government schemes nearly doubled at the state level, although considerable disparities persist. CONCLUSIONS: Changes in the level and distribution of MHFP funding from 2003 to 2012 were consistent with the relevant policy goals. However, improving efficiency requires further analysis to ascertain the impact of investments on health outcomes. This, in turn, will require better financial data systems as a precondition for improving the monitoring and accountability functions in Mexico.

[Correcting for misclassified HIV/aids deaths in Mexico: Retrospective analysis, 1983-2012]. / Corrección de la mala clasificación de las muertes por sida en México: Análisis retrospectivo de 1983 a 2012.

OBJECTIVE: To identify and reassign misclassified AIDS deaths in Mexico, reconstructing the time series of mortality from 1983 to 2012, by state, sex, age, and affiliation to social security. MATERIALS AND METHODS: 15.5 million deaths from 1979 to 2012 were analyzed. The HIV-AIDS mortality correction was done in three phases: a) those causes directly related to AIDS; b) by miscoded deaths, and c) AIDS deaths hidden in other underlying causes of death. Age-standardized rates of mortality (SMR) were calculated by sex, affiliation to social security, and state. RESULTS: 107 981 AIDS deaths from 1983 to 2012 were accumulated, representing 11% of total deaths observed for the period. The SMR in men for all age groups begins to decline since 1996, while for women the decline started in 2008. A similar picture is observed for the population with / without social security. Heterogeneity is a feature for SMR by state. CONCLUSION: An easily replicable methodology for the correction of mortality from AIDS, which generates relevant information for decision making based on the evidence is presented.

Objetivo. Identificar y reasignar defunciones mal clasificadas por sida en México, y reconstruir la mortalidad 1983-2012, por entidad federativa, sexo, edad y derechohabiencia a la seguridad social. Material y métodos. Se analizaron 15.5 millones de defunciones de 1979 a 2012. La corrección de la mortalidad por sida se hizo en tres fases: a) por causas directamente relacionadas con sida, y b) por muertes mal codificadas; c) muertes por sida ocultas en otras causas. Se calcularon tasas estandarizadas por edad de mortalidad (TEM) por sexo, derechohabiencia a la seguridad social y entidad federativa. Resultados. Se acumularon 107981 muertes por sida entre 1983 y 2012 (11% más del total de muertes observadas). La TEM en hombres, para todos los grupos de edad, empieza a descender desde 1996, mientras que para las mujeres la caída inicia en 2008. Un panorama similar se observa para la población con/sin seguridad social. La heterogeneidad caracteriza la TEM estatal. Conclusión. Se presenta una metodología fácilmente replicable para la corrección de la mortalidad de sida que genera información relevante para la toma de decisiones fundamentada en la evidencia.
