Epidemiology of chronic kidney disease in Peru and its relation to social determinants of health.

BACKGROUND: Chronic kidney disease (CKD) is a growing public health problem and an important cause of morbidity and mortality. Disparities in CKD may be related to social determinants and health inequalities in low- and middle-income countries. This study determined how social determinants of health influence trends in the prevalence and mortality of CKD in Peru. METHODS: This was an ecological study based on a secondary analysis of health care and death records obtained from the Ministry of Health of Peru for the period 2010-2016. The standardized prevalence and mortality rates of CKD were descriptively reported using geospatial exploratory analysis. We also determined the association with social determinants of health according to the domains suggested by Healthy People 2020. RESULTS: In the studied period, CKD prevalence increased by 300% and was associated with the health insurance coverage rate (ß=5.9 [95% CI 0.82 to 10.92]), proportion of people with a secondary education level (ß=11.4 [95% CI 1.94 to 20.93]), mean age (ß=-10.7 [95% CI -19.33 to -2.12]), monetary poverty rate (ß=-2.2 [95% CI -3.88 to -0.60]) and gross domestic product per capita (ß=-63.2 [95% CI -117.81 to -8.52]). The standardized mortality decreased by 10% and was associated with mean age (ß=-0.6 [95% CI -1.22 to -0.06]) and the proportion of people with a primary education level (ß=-0.5 [95% CI -0.9 to -0.05]). CONCLUSIONS: During the period 2010-2016, the prevalence of CKD increased and the mortality associated with CKD decreased. The observed changes were associated with some social determinants of health, such as increased health coverage and education. The health system of Peru must be prepared to take on the challenge.

National trends in age-standardized incidence and mortality rates of acute kidney injury in Peru.

INTRODUCTION: Acute kidney injury (AKI) is a common disorder that causes high healthcare costs. There are limited epidemiological studies of this disorder in low- and middle-income countries. The aim of this study was to describe trends in the age-standardized incidence and mortality rates of AKI in Peru. METHODS: We conducted an ecological study based on a secondary data sources of the basic cause of death from healthcare and death records obtained from establishments of the Ministry of Health of Peru for the period 2005-2016. The age-standardized incidence and mortality rates of AKI were described by region and trend effects were estimated by linear regression models. RESULTS: During the period 2005-2016, 26,633 cases of AKI were reported nationwide. The age-standardized incidence rate of AKI per 100,000 people increased by 15.2%, from 10.5 (period 2005-2010) to 12.1 (period 2011-2016). During the period 2005-2016, 6,812 deaths due to AKI were reported, which represented 0.49% of all deaths reported for that period in Peru. The age-standardized mortality rate of AKI per 100,000 people decreased by 11.1%, from 2.7 (period 2005-2010) to 2.4 (period 2011-2016). The greatest incidence and mortality rates were observed in the age group older than 60 years. CONCLUSIONS: During the study period, incidence of AKI increased and mortality decreased, with heterogeneous variations among regions.

INTRODUCTION: The incidence of thyroid cancer has increased worldwide. Peru has few reports describing the national and regional epidemiology of thyroid cancer. OBJECTIVE: The incidence of thyroid cancer has increased worldwide. Peru has few reports describing the national and regional epidemiology of thyroid cancer. METHODS: A descriptive study of trends was conducted with secondary data obtained from a public information source in Peru. The ICD 10: C73.0 coding record was evaluated, by age group, year and region. The age-standardized prevalence (period 2005 to 2016) and mortality (period 2005 to 2015) were calculated by region and year of study. RESULTS: In the 2005-2016 period, 19 513 cases of thyroid cancer were recorded. The age group with the highest frequency was 30 to 59 years (57.7%). The prevalence increased from 4.7 to 15.2 cases per 100 000 inhabitants in the period 2005-2016, with the coastal region showing the greatest increase. Likewise, 1596 deaths from thyroid cancer (period 2005 to 2015) were recorded, more frequently in those older than 60 years (75.5%). The age-standardized mortality rate increased from 0.67 in 2005 to 0.72 in 2015, being the highlands the one with the greatest increase. CONCLUSIONS: The prevalence of thyroid cancer increased and mortality remained constant in the period studied. These results suggest exploring social and population factors that may have influenced these results. Likewise, population records of this and other neoplasms in Peru should be improved.

INTRODUCCIÓN: La incidencia de cáncer de tiroides se ha incrementado en el mundo. En Perú existen limitados informes que describan la epidemiología nacional y regional de esta neoplasia. OBJETIVO: Describir la tendencia de la prevalencia y mortalidad de cáncer de tiroides registrada en el Ministerio de Salud de Perú. MÉTODOS: Se realizó un estudio descriptivo de tendencias con datos secundarios, obtenidos de una fuente de información pública de Perú. Se evaluó el registro de codificación CIE 10: C73.0, por grupo de edad, año y región. Se calcularon las tasas estandarizadas de la prevalencia (periodo 2005 a 2016) y mortalidad (periodo 2005 a 2015) por regiones y año de estudio. RESULTADOS: Durante el periodo 2005-2016 se registraron 19 513 casos de cáncer de tiroides. El grupo etario con mayor frecuencia fue de 30 a 59 años (57,7%). La prevalencia incrementó de 4,7 a 15,2 casos por 100 000 habitantes en el periodo 2005-2016 y la región de la costa fue la que presentó mayor ascenso. Asimismo, se registraron 1596 muertes por cáncer de tiroides (periodo 2005 a 2015) con mayor frecuencia en mayores de 60 años (75,5%). La tasa estandarizada de mortalidad por 100 000 habitantes aumentó de 0,67 en 2005 a 0,72 en 2015, siendo la región de la sierra la de mayor incremento. CONCLUSIONES: La prevalencia por cáncer de tiroides aumentó y la mortalidad se mantuvo constante en el periodo estudiado. Estos resultados animan a explorar factores sociales y de la población que hayan podido influir en ello; además de mejorar los registros poblacionales de esta y otras neoplasias en Perú.

RESUMO Introdução: A lesão renal aguda (LRA) é um distúrbio comum que causa altos custos para a saúde. Existem estudos epidemiológicos limitados sobre esse distúrbio em países de baixa e média renda. O objetivo deste estudo foi descrever as tendências nas taxas de incidência e mortalidade padronizadas por idade da LRA no Peru. Métodos: Realizamos um estudo ecológico com base em fontes de dados secundárias da causa básica de morte de registros de saúde e óbito obtidos de estabelecimentos do Ministério da Saúde do Peru no período de 2005 a 2016. A incidência padronizada por idade e as taxas de mortalidade por LRA foram descritas por região, e os efeitos de tendência foram estimados por modelos de regressão linear. Resultados: No período de 2005 a 2016, 26.633 casos de LRA foram relatados em todo o país. A taxa de incidência padronizada de LRA por idade por 100.000 pessoas aumentou 15,2%, de 10,5 (período de 2005 a 2010) para 12,1 (período de 2011 a 2016). Durante o período de 2005 a 2016, foram relatadas 6.812 mortes por LRA, o que representou 0,49% de todas as mortes relatadas para esse período no Peru. A taxa de mortalidade por LRA padronizada por idade por 100.000 pessoas diminuiu 11,1%, de 2,7 (período de 2005 a 2010) para 2,4 (período de 2011 a 2016). As maiores taxas de incidência e mortalidade foram observadas na faixa etária acima de 60 anos. Conclusões: Durante o período do estudo, a incidência de LRA aumentou e a mortalidade diminuiu, com variações heterogêneas na epidemiologia entre as regiões.
