A century after its discovery, Chagas disease (CD) is still considered a public health problem. Mortality caused by CD between 2000 and 2010 was described according to the specific underlying cause, year of occurrence, gender, age range, and region of Brazil. The standardized mortality rate decreased 32.4%, from 3.4% in 2000 to 2.3% in 2010. Most of the deaths (85.9%) occurred in male patients who were > 60 years of age caused by cardiac involvement. The mortality rate caused by cardiac involvem ...[more]

Project description:BackgroundPatients with cardiovascular disease (CVD) tend to have higher mortality rates and reduced physical activity (PA). We aimed to evaluate the effect of PA on mortality in older adults with specific CVD.MethodsWe enrolled 68,223 participants (n = 23,871 with CVD, n = 44,352 without CVD) aged ≥65 years with available physical activity data between 2005 and 2012 from the Korean National Health Insurance Service of Korea-Senior database. CVD was defined as a history of ischemic stroke, transient ischemic attack, heart failure, myocardial infarction, and peripheral artery disease.ResultsPatients with CVD were older than those without CVD. Compared with the sedentary group, the physically active groups with and without CVD had a lower incidence and risk of all-cause death during a median follow up period of 42 (interquartile range 30-51) months. A 500 metabolic equivalent task-min/week increase in PA resulted in an 11% and 16% reduction in the risk of mortality in the non-CVD and CVD groups, respectively. With regard to specific CVDs, the risk of mortality progressively reduced with increasing PA in patients with heart failure or myocardial infarction. However, the reduction reached a plateau in patients with stroke or peripheral artery disease, but was significantly greater in patients with stroke (20% vs. without stoke, 11%, Pint = 0.006) or heart failure (13% vs. without heart failure, 11%; Pint = 0.045).ConclusionsPA was associated with a reduced risk of all-cause mortality in older adults with and without CVD. The benefits of PA in patients with CVD, especially patients with stroke or heart failure, were greater than those without.

Project description:BackgroundMortality during and after incarceration is poorly understood in low- and middle-income countries (LMICs). The need to address this knowledge gap is especially urgent in South America, which has the fastest growing prison population in the world. In Brazil, insufficient data have precluded our understanding of all-cause and cause-specific mortality during and after incarceration.Methods and findingsWe linked incarceration and mortality databases for the Brazilian state of Mato Grosso do Sul to obtain a retrospective cohort of 114,751 individuals with recent incarceration. Between January 1, 2009 and December 31, 2018, we identified 3,127 deaths of individuals with recent incarceration (705 in detention and 2,422 following release). We analyzed age-standardized, all-cause, and cause-specific mortality rates among individuals detained in different facility types and following release, compared to non-incarcerated residents. We additionally modeled mortality rates over time during and after incarceration for all causes of death, violence, or suicide. Deaths in custody were 2.2 times the number reported by the national prison administration (n = 317). Incarcerated men and boys experienced elevated mortality, compared with the non-incarcerated population, due to increased risk of death from violence, suicide, and communicable diseases, with the highest standardized incidence rate ratio (IRR) in semi-open prisons (2.4; 95% confidence interval [CI]: 2.0 to 2.8), police stations (3.1; 95% CI: 2.5 to 3.9), and youth detention (8.1; 95% CI: 5.9 to 10.8). Incarcerated women experienced increased mortality from suicide (IRR = 6.0, 95% CI: 1.2 to 17.7) and communicable diseases (IRR = 2.5, 95% CI: 1.1 to 5.0). Following release from prison, mortality was markedly elevated for men (IRR = 3.0; 95% CI: 2.8 to 3.1) and women (IRR = 2.4; 95% CI: 2.1 to 2.9). The risk of violent death and suicide was highest immediately post-release and declined over time; however, all-cause mortality remained elevated 8 years post-release. The limitations of this study include inability to establish causality, uncertain reliability of data during incarceration, and underestimation of mortality rates due to imperfect database linkage.ConclusionsIncarcerated individuals in Brazil experienced increased mortality from violence, suicide, and communicable diseases. Mortality was heightened following release for all leading causes of death, with particularly high risk of early violent death and elevated all-cause mortality up to 8 years post-release. These disparities may have been underrecognized in Brazil due to underreporting and insufficient data.

Project description:To assess whether women with a history of hypertensive disease of pregnancy have increased risk for early adult mortality.In this retrospective cohort study, women with one or more singleton pregnancies (1939-2012) with birth certificate information in the Utah Population Database were included. Diagnoses were categorized into gestational hypertension; preeclampsia; hemolysis, elevated liver enzymes, and low platelet count syndrome; and eclampsia. Women with more than one pregnancy with hypertensive disease (exposed) were included only once, assigned to the most severe category. Exposed women were matched one to two to unexposed women by age, year of childbirth, and parity at the time of the index pregnancy. The causes of death were ascertained using Utah death certificates and the fact of death was supplemented with the Social Security Death Index. Hazard ratios for cause-specific mortality among exposed women compared with unexposed women were estimated using Cox regressions adjusting for neonatal sex, parental education, preterm delivery, race-ethnicity, and maternal marital status.A total of 60,580 exposed women were matched to 123,140 unexposed women; 4,520 (7.46%) exposed and 6,776 (5.50%) unexposed women had died by 2012. All-cause mortality was significantly higher among women with hypertensive disease of pregnancy (adjusted hazard ratio [HR] 1.65, 95% confidence interval [CI] 1.57-1.73). Exposed women's greatest excess mortality risks were from Alzheimer disease (adjusted HR 3.44, 95% CI 1.00-11.82), diabetes (adjusted HR 2.80, 95% CI 2.20-3.55), ischemic heart disease (adjusted HR 2.23, 95% CI 1.90-2.63), and stroke (adjusted HR 1.88, 95% CI 1.53-2.32).Women with hypertensive disease of pregnancy have increased mortality risk, particularly for Alzheimer disease, diabetes, ischemic heart disease, and stroke.

Project description:BackgroundA better understanding of performance in functional mobility tasks related to the mortality patterns for the different causes of death for the Brazilian older population is still a challenge.ObjectiveTo analyze if gait speed and chair stand test performance are associated with mortality in older adults, and if the overall mobility status changes the effect of other mortality risk factors.MethodsThe data were from SABE (Health, Well-being and Aging Study), a multiple-cohort study conducted in São Paulo, Brazil, with a representative sample of people aged 60 and more. Cox regression models were used to analyze 10-year all-cause and cause-specific mortality with consideration for gait speed and the chair stand test.ResultsOf the 1411 participants, 26% died during the follow-up. The performance in the chair stand test had a more consistent association with mortality (hazard ratio (HR)=1.03, 95%CI: 1.00, 1.05) than gait speed. Being unable to perform the test also increased the risk to die by all-cause (HR=1.71, 95%CI: 1.21, 2.42) and by diseases of the circulatory system (HR=2.14, 95%CI: 1.25, 3.65). The stratified analysis of mobility performance changed the effects of some of the mortality risk factors, such as cognitive impairment and multimorbidity.ConclusionsThe chair stand test could be a better choice than 3-meters walking test as a mortality predictor. In addition, the impact of cognitive decline and multimorbidity were greater among those with reduced mobility, supporting the development of preventive interventions and public policies targeted at more vulnerable groups of older adults.

Project description:BackgroundAmbient air pollution is a modifiable risk factor for cardiovascular disease, yet uncertainty remains about the size of risks at lower levels of fine particulate matter (PM2.5) exposure which now occur in the USA and elsewhere.MethodsWe investigated the relationship of ambient PM2.5 exposure with cause-specific cardiovascular disease mortality in 565 477 men and women, aged 50 to 71?years, from the National Institutes of Health-AARP Diet and Health Study. During 7.5 x 106 person-years of follow up, 41 286 cardiovascular disease deaths, including 23 328 ischaemic heart disease (IHD) and 5894 stroke deaths, were ascertained using the National Death Index. PM2.5 was estimated using a hybrid land use regression (LUR) geostatistical model. Multivariate Cox regression models were used to estimate relative risks (RRs) and 95% confidence intervals (CI).ResultsEach increase of 10 ??g/m3 PM2.5 (overall range, 2.9-28.0? ?g/m3) was associated, in fully adjusted models, with a 16% increase in mortality from ischaemic heart disease [hazard ratio (HR) 1.16; 95% CI 1.09-1.22] and a 14% increase in mortality from stroke (HR 1.14; CI 1.02-1.27). Compared with PM2.5 exposure <8? ?g/m3 (referent), risks for CVD were increased in relation to PM2.5 exposures in the range of 8-12? ?g/m3 (CVD: HR 1.04; 95% CI 1.00-1.08), in the range 12-20? ?g/m3 (CVD: HR 1.08; 95% CI 1.03-1.13) and in the range 20+ ?g/m3 (CVD: HR 1.19; 95% CI 1.10-1.28). Results were robust to alternative approaches to PM2.5 exposure assessment and statistical analysis.ConclusionsLong-term exposure to fine particulate air pollution is associated with ischaemic heart disease and stroke mortality, with excess risks occurring in the range of and below the present US long-term standard for ambient exposure to PM2.5 (12? µg/m3), indicating the need for continued improvements in air pollution abatement for CVD prevention.

Project description:BackgroundChagas disease (CD) is a neglected chronic parasitic infection and a public health problem that is preventable, and has serious complications. In this study, the effects of age, period and birth cohort (APC Effects) on the evolution of the mortality of that disease in Brazil, from 1980-2014, according to sex and geographic region of the country, were analyzed. Mortality forecasts from the years 2015 to 2034 were estimated.MethodsThis is an ecological cross-sectional study in which death records and population data were extracted from the DATASUS (Department of Information Technology of the National Health System) website, in age groups from 20-24 years of age to 80 years and over, from 1980 to 2014. The rates were standardized according to age and sex distributions using the direct method. The APC models were estimated using the Bayesian approach, and the INLA (Integrated Nested Laplace Approximations) method was used for parameter inference. Super dispersion of the data was considered, and we included unstructured random terms in the models.ResultsDuring the analyzed period, there were 178,823 deaths in Brazil (3.85 annual deaths per 100,000 inhabitants). It was found that temporal effects on CD mortality varied by sex and region. In general, there was an increase in mortality rates up to 30 years of age, and the mortality rates were higher between 50 and 64 years of age. On average, men died five years younger than women. Mortality rates were highest in the Central West and Southeast regions. The Central West, Southeast and Southern regions had a reduction over time in the rate of CD deaths between 2000 and 2014. The mortality rate in the Northeast was not statistically different in any period analyzed, while the North had tendency to increase; however, a significant risk increase was only observed between 1995 and 1999. The rate of mortality was high in older birth cohorts. The overall prediction for the next two decades showed a progressive decline in CD mortality, which will be highest among the young. The expected average reduction was 76.1% compared to the last observed period (2010-2014) and the last predicted (2030-2034) period. The average reduction ranged from 86% in the 20-24 age group to 50% in the 80 and over age group.ConclusionsIn the present study, a higher death rate was observed for ages above 30 years, especially 50 to 64 years, and in the older birth cohorts. We believe these results can be related to period effects of vector control actions and preventive and care measures by the health system of Brazil, in addition to demographic changes in the period. The differences among the regions reflect socioeconomic inequities and access to the healthcare systems in the Brazilian population.

Project description:ImportanceHispanics are the largest minority group in the United States and face a disproportionate burden of risk factors for cardiovascular disease (CVD) and low socioeconomic position. However, Hispanics paradoxically experience lower all-cause mortality rates compared with their non-Hispanic white (NHW) counterparts. This phenomenon has been largely observed in Mexicans, and whether this holds true for other Hispanic subgroups or whether these favorable trends persist over time remains unknown.ObjectiveTo disaggregate a decade of national CVD mortality data for the 3 largest US Hispanic subgroups.Design, setting, and participantsDeaths from CVD for the 3 largest US Hispanic subgroups-Mexicans, Puerto Ricans, and Cubans-compared with NHWs were extracted from the US National Center for Health Statistics mortality records using the underlying cause of death based on coding from the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (I00-II69). Mortality data were evaluated from January 1, 2003, to December 31, 2012. Population estimates were calculated using linear interpolation from the 2000 and 2010 US Census reports. Data were analyzed from November 2015 to July 2016.Main outcomes and measuresMortality due to CVD.ResultsParticipants included 688 074 Mexican, 163 335 Puerto Rican, 130 397 Cuban, and 19 357 160 NHW individuals (49.0% men and 51.0% women; mean [SD] age, 75 [15] years). At the time of CVD death, Mexicans (age, 67 [18] years) and Puerto Ricans (age, 68 [17] years) were younger compared with NHWs (age, 76 [15] years). Mortality rates due to CVD decreased from a mean of 414.2 per 100 000 in 2003 to 303.3 per 100 000 in 2012. Estimated decreases in mortality rate for CVD from 2003 to 2012 ranged from 85 per 100 000 for all Hispanic women to 144 per 100 000 for Cuban men, but rate differences between groups vary substantially, with Puerto Ricans exhibiting similar mortality patterns to NHWs, and Mexicans experiencing lower mortality. Puerto Ricans experienced higher mortality rates for ischemic and hypertensive heart disease compared with other subgroups, whereas Mexicans experienced higher rates of cerebrovascular disease deaths.Conclusions and relevanceSignificant differences in CVD mortality rates and changes over time were found among the 3 largest Hispanic subgroups in the United States. Findings suggest that the current aggregate classification of Hispanics masks heterogeneity in CVD mortality reporting, leading to an incomplete understanding of health risks and outcomes in this population.

Project description:BackgroundIschemic heart disease (IHD) is the leading cause of death among cardiovascular diseases (CVD).ObjectiveTo describe the sociodemographic profile and analyze the trend in the mortality rate due to IHD, according to sex and by age group, in the states of the Northeast region of Brazil, from 1996 to 2016.MethodsEcological study involving IHD mortality in the northeastern states. Variables analyzed: sex, age, education, marital status, ICD-10 category and state of residence. Crude and standardized rates were calculated. Death data were collected from the Mortality Information System (SIM) and population data from the Brazilian Institute of Geography and Statistics (IBGE). In temporal analyzes the regression model by inflection points was used, with the calculation of annual percent change (APC) and average annual percent change of the period (AAPC). A 95% confidence interval and a significance level of 5% were considered.Results405916 deaths due to IHD were registered in the northeast region during the study period. The death profile is characterized by men (n=229006; 56,42%), elderly (n=301379; 74,25%), race/color brown (n=197936; 48,76%), elementary or <4 years at school (n=232599; 57,30%) and married (n=179599; 44,25%). There was an unusual highlight to the increase in the annual growth rate in the age group of adolescents (AAPC: 5,2%, p <0.01). The standardized regional mortality rate grew from 30,7 per 100,000 inhabitants in 1996 to 53.8 per 100,000 in 2016 (AAPC 2.8%; p<0.01). All nine states presented a statistically significant growth trend, with emphasis on Maranhão (AAPC 7,6%; p<0.01) and Piauí (AAPC 6,0%; p<0.01).ConclusionThe prevalent observed profile was male, elderly, race/color brown, low education level and married. Mortality due to IHD presented an upward trend in all states, although with an uneven pattern among the federated units.

Project description:BackgroundIntake of conventionally grown fruits and vegetables (FVs) is an important route of exposure to pesticide residues in the general population. However, whether health risk stemming from exposure to pesticides through diet could offset benefits of consuming FVs is unclear.ObjectiveWe assessed the association of FV intake, classified according to their pesticide residue status, with total and cause-specific mortality.MethodsWe followed 137,378 women (NHS, 1998-2019, and NHSII, 1999-2019) and 23,502 men (HPFS, 1998-2020) without cardiovascular disease, cancer, or diabetes at baseline. FV intake was assessed using validated food frequency questionnaires and categorized as having high- or low-pesticide-residues using data from the USDA Pesticide Data Program. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CI) for total and cause-specific mortality associated with high- and low-pesticide-residue FV intake.ResultsA total of 27,026 deaths, including 4,318 from CVD and 6,426 from cancer, were documented during 3,081,360 person-years of follow-up. In multivariable-adjusted analyses, participants who consumed ≥4 servings/day of low-pesticide-residue FVs had 36% (95% CI: 32%-41%) lower mortality risk compared to participants who consumed <1 serving/day. The corresponding estimate for high-pesticide residue FV intake was 0.93 (95% CI: 0.81-1.07). This pattern was similar across the three most frequent causes of death (cardiovascular disease, cancer and respiratory diseases).ConclusionsHigh-pesticide-residue FV intake was unrelated whereas low-pesticide residue FV intake was inversely related to all-cause mortality, suggesting that exposure to pesticide residues through diet may offset the beneficial effect of FV intake on mortality.
