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.

Tendências de Mortalidade por Câncer Bucal no Brasil por Regiões e Principais Fatores de Risco / Trends in Oral Cancer Mortality in Brazil by Region and main Risk Factors / Tendencias de la Mortalidad por Cáncer Bucal en Brasil por Región y Principales Factores de Riesgo

Introdução: O câncer bucal ainda é destacado como preocupante problema de saúde pública. Objetivo: Verificar a tendência de mortalidade por câncer bucal por Região brasileira e fatores de risco, avaliando o intervalo de tempo entre o diagnóstico e o tratamento. Método: Estudo com dados secundários do DATASUS (taxa de mortalidade e tempo para tratamento) e do Vigitel (consumo de álcool e cigarro); análises de séries temporais e correlações entre taxas de mortalidade (2010-2019) e consumo de álcool e cigarro (2010-2019), para idade superior a 40 anos, e análise descritiva do tempo entre diagnóstico e tratamento. Resultados: Houve aumento da tendência de câncer bucal por Regiões e sexo, com predominância para o sexo masculino. A variação percentual anual (VPA) da ingestão de álcool e o uso de cigarro foram considerados estacionários na maioria das Regiões analisadas. Ao correlacionar as variáveis, verificou-se correlação estatisticamente significativa entre taxa de mortalidade (2010-2019) e percentual de consumo de álcool (p=0,011; r=0,957), percentual de consumo de cigarro (p=0,019; r=0,936) e taxa bruta de mortalidade em homens (2019) (p=0,005; r=0,97). Verificou-se que, na maioria dos casos (74%), o tempo para início do tratamento é de mais de 60 dias. Conclusão: Embora o consumo de álcool e o tabagismo sejam fatores de risco para o câncer bucal, o presente estudo concluiu que houve aumento da mortalidade por câncer e os fatores de risco analisados permaneceram estacionários. O início de tratamento foi maior do que 60 dias a partir do diagnóstico.

Introduction: Oral cancer still stands out as a concerning public health issue. Objective: Verify the trend of oral cancer mortality by Brazilian regions and risk factors, evaluating the time interval between diagnosis and treatment. Method: Study with secondary data from DATASUS (mortality rate and time to treatment) and Vigitel (alcohol and cigarette use). Time series analyzes and correlations were performed among mortality rates (2010-2019) and alcohol and cigarette use (2010-2019) for over 40 years of age. Descriptive analysis of the time between diagnosis and treatment was also performed. Results: There was an increase in the tendency to oral cancer by region and sex, with a predominance of males. The annual percentage change (APC) of alcohol intake and cigarette use was considered stationary in most regions analyzed. When correlating the variables, there was a statistically significant correlation for mortality rate (2010-2019) and percentage of alcohol use (p=0.011; r=0.957), percentage of cigarette use (p=0.019; r=0.936) and crude mortality rate in men (2019) (p=0.005; r=0.97). It was found that most cases (74%) take more than 60 days to start treatment. Conclusion: Although alcohol and tobacco use are risk factors for oral cancer, the present study showed an increase in cancer mortality and stationary for the risk factors analyzed. The beginning of the treatment was over 60 days after diagnosis

Introducción: El cáncer oral todavía se destaca como un problema de salud pública preocupante. Objetivo: Verificar la tendencia de la mortalidad por cáncer bucal por región brasileña y factores de riesgo, evaluando el intervalo de tiempo entre el diagnóstico y el tratamiento. Método: Estudio con datos secundarios de DATASUS (tasa de mortalidad y tiempo de tratamiento) y Vigitel (consumo de alcohol y cigarrillos). Se realizaron análisis de series de tiempo y correlaciones entre las tasas de mortalidad (2010-2019) y el consumo de alcohol y cigarrillos (2010-2019) para los mayores de 40 años. También se realizó un análisis descriptivo del tiempo transcurrido entre el diagnóstico y el tratamiento. Resultados: Hubo un incremento en la tendencia al cáncer bucal por región y sexo, con predominio del sexo masculino. El cambio porcentual anual (APV) de la ingesta de alcohol y el consumo de cigarrillos se consideró estacionario en la mayoría de las regiones analizadas. Al correlacionar las variables, hubo una correlación estadísticamente significativa para tasa de mortalidad en hombres (2010- 2019) y porcentaje de consumo de alcohol para hombres (p=0,011; r=0,957), porcentaje de consumo de cigarrillos en hombres (p=0,019; r=0,936) y tasa bruta de mortalidad en hombres (2019) (p=0,005; r=0,97). Se encontró que la mayoría de los casos (74%) demoran más de 60 días en comenzar el tratamiento. Conclusión: Aunque el consumo de alcohol y el tabaquismo son factores de riesgo para el cáncer oral, el presente estudio mostró un aumento en la mortalidad por cáncer y estacionario para los factores de riesgo analizados. Hubo un alto porcentaje de inicio del tratamiento durante 60 días después del diagnóstico

Effect of Human Development Index and other socioeconomic factors on mortality-to-incidence ratio of lips and oral cavity cancer in Mexican states: an ecological study.

OBJECTIVES: To assess the association between the Human Development Index (HDI) and covariates on the mortality-to-incidence ratio (MIR) of lips and oral cavity cancer (LOCC) in Mexico. DESIGN: Ecological study. SETTING: Data from 32 Mexican states for year 2019. PARTICIPANTS: Data set of male and female populations from Mexico. EXPOSURES: Socioeconomic conditions based on HDI and covariates related to healthcare system capacity (total health spending per capita, school dropout and ratio of medical personnel in direct contact with patients). PRIMARY AND SECONDARY OUTCOME MEASURES: MIR of LOCC by state and sex was calculated from the Global Burden of Disease Study website for year 2019. Data for calculating HDI 2019 by state and covariates were obtained from the National Institute of Statistics and Geography. A multiple regression model was constructed to measure the effects of HDI and covariates on LOCC-MIR. RESULTS: Among the states with the highest HDI (>0.780), Colima had the highest aged-standardised rates per 100.000 in men for incidence (5.026) and mortality (3.118). The greatest burden of the disease was found on men, with the highest Men:Women MIR in Colima (3.10) and Baja California Sur (2.73). The highest MIR (>0.65) was found among the states with the lowest HDI (Oaxaca and Chiapas). For each unit of increase of the HDI there was a decrease in the LOCC- MIR of -0.778, controlling for the covariates. The most suitable regression model explained the 57% (F (p): 0.000) of the variance. CONCLUSIONS: Men were most affected by LOCC in Mexican states. The highest MIRs of LOCC were found in the states with the highest HDI. But a worse prognosis of the disease, expressed as a higher MIR, is expected in contexts with lower HDI in the country, even with lower MIRs.

Relationship between the Human Development Index and its Components with Oral Cancer in Latin America.

To evaluate the relationship between the Human Development Index (HDI) and its components with oral cancer (OC) in Latin America. Ecological study in 20 Latin American countries in 2010 and 2017, which evaluated the relationship between the Age-Standardized Rates (ASRs) of incidence and mortality from oral cancer and the following indicators: HDI, with its components (income, education, and health indexes); and the Gini and Theil-L indexes. Among the countries with the highest HDI, men from Brazil and Cuba had the highest incidence and mortality ASRs per 100,000 inhabitants (ASR incidence >7.5 and mortality >4.5). Among those with the lowest HDI, Haiti was the most affected country (ASR incidence >4.1 and mortality >3.0). The highest male:female ratio was in Paraguay in both years (incidence >3.5 and mortality >4.0). Mortality from oral cancer is negatively related to the global HDI in both years, with regression coefficients (95% confidence interval) being -5.78 (-11.77, 0.20) in 2010 and -5.97 (-11.38, -0.56) in 2017; and separate (independent) from the income [-4.57 (-9.92, 0.77) in 2010 and -4.84 (-9.52, -0.17) in 2017] and health indexes [-5.81 (-11.10, -0.52) and -6.52 (-11.32, -1.72) in 2017] (p < 0.05) in the countries with lower HDI. Oral cancer incidence and mortality rates vary both among and within Latin American countries according to sex, with a greater burden on men. The HDI is negatively related to mortality from oral cancer in the countries of medium and low HDI.

[Effect of risk factor control policies on oral cancer mortality in Latin America]. / Efecto de las políticas de control de factores de riesgo sobre la mortalidad por cáncer oral en América Latina.

OBJECTIVE: Mortality from oral cancer, the prevalence of the main risk factors and the implementation of policies to control current trends and the distribution of data among the countries of Latin America. The objective of this study was to describe the trends of mortality from oral cancer between 2000 and 2017, by sex, in 20 countries in Latin America, and to know the effect of measures to control tobacco consumption and alcohol consumption on the Mortality from oral cancer. METHODS: Ecological study that evaluates the relationship between the rates standardized by the age of cancer by oral sex, the prevalence of tobacco consumption and alcohol consumption, and the implementation of control policies. To calculate the annual percentage change of the rates, the Prais-Winsten regression was used; and the effect of measures of control of risk factors on oral cancer mortality is assessed by Spearman correlations. RESULTS: The greatest decreases in oral cancer mortality were in men in Brazil (APC -7.83, -14.25,-0.93). Mortality from cancer the oral relationship between men and the prevalence of tobacco consumption and alcohol consumption (r = 0.358, r 0.537) (p <0.01), and between the non-implementation of control policies of smoking (r = 0.738) (p= 0.003), the restrictions on the hours and days of sale of alcohol (r = 0.777, p = 0.001), and the states on sponsorship and promotion of alcohol sales (r =0.739 , p =0.040). CONCLUSIONS: The effect of the implementation of control policies is evidenced by a greater relationship with oral cancer mortality in the countries with the least progress in their execution.

OBJETIVO: La mortalidad por cáncer oral, la prevalencia de los principales factores de riesgo y la implementación de las políticas para su control presentan tendencias y distribución desiguales entre los países de América Latina. El objetivo de este trabajo fue describir las tendencias de la mortalidad por cáncer oral entre 2000 y 2017, según sexos, en 20 países de América Latina, y conocer el efecto de las medidas de control del consumo de tabaco y el consumo de alcohol sobre la mortalidad por cáncer oral. METODOS: Estudio ecólogico que evaluó la relación entre las tasas estandarizadas por edad del fallecimiento por cáncer oral según el sexo, la prevalencia del consumo de tabaco y del consumo de alcohol,y la implementación de las políticas de control. Para calcular la variación porcentual de cambio anual de las tasas, se usó la regresión Prais-Winsten; y el efecto de las medidas de control de los factores de riesgo sobre la mortalidad por cáncer oral se evalúo mediante correlaciones de Spearman. RESULTADOS: Los mayores descensos en la mortalidad por cáncer oral fueron en los hombres de Brasil (APC -7,83; -14,25; -0,93). La mortalidad por cáncer oral mostró relación positiva entre hombres y la prevalencia del consumo de tabaco y del consumo de alcohol (r=0,358, r=0,537) (p<0,01), y entre la no implementación de las políticas de control de tabaquismo (r=0,738) (p=0,003), las restricciones en los horarios y días de venta de alcohol (r=0,737, p=0,001), y los reglamentos sobre patrocinio y promoción de venta de alcohol (r=0,739, p=0,040). CONCLUSIONES: El efecto de la implementación de las políticas de control se evidencia en una mayor relación con la mortalidad por cáncer oral en los países con menor avance en su ejecución.

[72-month evaluation of an oral health prevention strategy in schoolchildren]. / Evaluación a 72 meses de una estrategia de prevención en salud oral en escolares.

OBJECTIVE: Given the high prevalence of caries and periodontal disease globally, and its cumulative process from an early age, effective strategies are required to influence healthy habits that are formed in a sustainable manner, taking advantage of common spaces such as school. The objective was to evaluate for 72 months an oral health prevention strategy in schoolchildren. METHODS: This quasi-experimental study considered an initial sample of 350 students with similar cultural and socioeconomic conditions, which was later reduced to 220, after the 72 months. The tooth brushing practice was carried out at school daily; with teacher motivation and leader in oral health formation. Intervention was supervised all time long. to At the beginning and end of the 72 months, the following epidemiological indexes were taken: Silness-Loe plaque index, Loe-Silness Gingival index, brushing skill index by Simmons Smith & Gelbie (ISSG), and the MEDI-MED index that dichotomically considered: healthy permanent teeth, health of the gums and good attitude towards dental health. The statistical analysis included measures of central tendencies. The difference in averages of the indices was determined by the Mann-Whitney U test. RESULTS: The average of the indices: initial (II) and final (IF) registered as follows: gingival (II: 0.63-IF: 0.27) and bacterial plaque (II: 0.99-IF: 0.41) with a difference p <0.05. The index (ISSG) indicated a dental plaque removal of 82.18%.MEDI-MED index "healthy permanent teeth" (II: 91% - IF: 59%); Gum (II: 14% - IF: at 85%) and the "Mind" component (II: 96% - IF: 87%). CONCLUSIONS: The preventive strategy evaluated significantly reduced the rates of bacterial and gingival plaque. The MEDI-MED index indicated decreased in healthy permanent teeth and a positive attitude towards dentistry.

Social Media Marketing Strategy Applied to Oral Hygiene / Estrategia de Marketing Social Aplicado a Higiene Dental

ABSTRACT: This project aims to apply psychological strategies based on social media marketing in order to set an oral hygiene habit in school-aged children to prevent dental caries in the long term. This is a descriptive study that assessed the recall of an oral hygiene campaign based on social media marketing of 34 school-aged children, 24 months after the end of the campaign. The instrument allowed the assessment of the advertising campaign, according to different levels of recall. The findings were confirmed with oral health epidemiological indices. Most of the school-aged children recalled "brushing teeth" as the campaign message and all of them expressed interest in the campaign to be repeated. Plaque index and brushing technique suggested that the school-aged children group has a good level of dental plaque removal after 24 months after the end of the social media marketing campaign. The required behavioral modification demands changes both at micro (individual) level and at macro levels of the organizations, in a short and a long term, as well as the participation of all actors involved in establishing healthy oral habits as a norm in the society. This study contributes to the transformative potential of social media marketing by understanding habits formation such as interaction among different stimuli within a favorable context.

RESUMEN: Este proyecto tiene como objetivo aplicar estrategias sicológicas basadas en el marketing social para la fijación del hábito de la higiene oral en escolares como medida de prevención de la caries dental a largo término. Se trata de un estudio descriptivo el cual se utilizó para evaluar el recordatorio de una campaña de higiene oral fundamentada en el marketing social en 34 escolares tras 24 meses de la campaña original. El instrumento permitió la evaluación de la campaña publicitaria, según los diferentes niveles de recuerdo, y los hallazgos fueron corroborados con índices epidemiológicos de salud oral. El mayor porcentaje de escolares recordó el mensaje de la campaña "cepillarse los dientes", todos manifestaron querer que la campaña se repitiera. El índice de placa dental y de cepillado indicó que el grupo de escolares encuestados tiene un buen nivel de remoción de placa dental, después de 24 meses de haber terminado la campaña de marketing social. Implicaciones sociales: la modificación requerida de comportamiento, demanda cambios tanto a nivel micro (individuo), de las organizaciones y a nivel macro tanto a corto como a largo plazo; así como la participación de todos los actores involucrados en lograr que los hábitos orales saludables se conviertan en una norma en la sociedad. Originalidad/valor: este estudio contribuye al potencial de transformación del marketing social ubicando la generación de hábitos como la interacción entre diferentes estímulos dentro de un contexto favorable.
