Background: The aims of the study was to evaluate the psychometric properties and to characteristics of a scale on research skills as well as to characterize the experience of university thesis students using information databases (i.e., Scopus or Web of Science) and bibliographic reference managers. Methods: A sample of 1598 university students from five departments, acroos the different cam- puses of one Peruvian university. The psychometric properties of the instrument were evaluated using factor analysis and measurement invariance according to sex and age groups. In addition, an internal consistency analysis was conducted for scale reliability using Cronbach’s alpha, ordinal alpha, and the omega index. Results: Our study identified that the unidimensional model with correlated errors showed adequate indicators of reliability and goodness of fit, with the exception of the RMSEA, whi...

Background: Breast cancer is among the leading cause of cancer-related mortality among Latin American and Caribbean (LAC) women, but a comprehensive and updated analysis of mortality trends is lacking. The objective of this study was to determine the breast cancer mortality rates between 1997 and 2017 for LAC countries and predict mortality until 2030. Methods: We retrieved breast cancer deaths across 17 LAC countries from the World Health Organization mortality database. Age-standardized mortality rates per 100,000 women-years were estimated. Mortality trends were evaluated with Joinpoint regression analyses by country and age group (all ages, < 50 years, and ≥ 50 years). By 2030, we predict number of deaths, mortality rates, changes in population structure and size, and the risk of death from breast cancer. Results: Argentina, Uruguay, and Venezuela reported the highest mortality...

Background: Schools are increasingly experiencing physical, psychological, and sexual violence, which impacts students’ academic achievement and physical and emotional health. Our objective was to identify regional prevalence rates, average prevalence by aggressor type, and provincial spatial conglomerates with higher rates for each type of school violence reported in educational settings in Peru during 2019. Methods: An analysis was made of 12,132 cases reported through Peru’s Specialized School Violence System (SíseVe). The Moran indices were calculated using provincial prevalence rates to identify conglomerates with high prevalence. Results: In the coast region, the Department of Tacna reported the highest prevalence rates for physical (99.7) and psychological (107); the Department of Amazonas, which is in the jungle, reported the highest prevalence rate for sexual violence (74.6...

Antecedentes: La evidencia sobre los efectos a largo plazo de múltiples condiciones cardiovasculares a la vez en términos de mortalidad, en entornos de bajos recursos, es limitada. Objetivo: Se describió si la agregación y combinación por pares de factores de riesgo cardiovascular (FRCV) se correlacionan con la mortalidad por todas las causas a 10 años. Métodos: Se describió la mortalidad por todas las causas a 10 años para los participantes inscritos originalmente en el estudio PERU MIGRANT (línea de base en 2007) a través del Registro Nacional de Identificación y Estado Civil. Los FRCV fueron: hipertensión, diabetes mellitus tipo 2, hipercolesterolemia y sobrepeso/obesidad. Las exposiciones fueron, la agregación de FRCV seleccionados (uno, dos y tres o más FRCV); y combinaciones por pares de FRCV. Se utilizaron modelos de regresión de Cox para calcular las razones de ri...

“Objective Describe the occupational characteristics of farmer and non-farmer workers and investigate critical occupational risk factors for mental disorders in sugarcane farmers in Peru. Method We conducted a cross-sectional study with occupational health and safety focus among farmers and non-farmers. Mental disorder symptoms were evaluated through the local validated version of the 12-Item General Health Questionnaire (GHQ-12). We explored the association between mental disorder symptoms, work conditions and known occupational risk factors (weekly working hours, pesticide exposures, heat stress and heavy workload). Negative binomial regression models were fitted, and 95% CIs were calculated. Results We assessed 281 workers between December 2019 and February 2020. One hundred and six (37.7%) respondents identified themselves as farmworkers. The mean GHQ-12 scores for farmers and non-...

El presente libro resume los hallazgos principales del Estudio Poblacional Bio-sociodemográfico y de Prevalencia por Autorreporte de Enfermedades No-transmisibles en Chimbote 2016-2017, un proyecto de gran envergadura patrocinado por la Universidad Católica Los Ángeles de Chimbote. Esta investigación, liderada por nuestro Rector Julio Domínguez Granda, alcanzó a recolectar información de más de 60 000 habitantes de nuestra ciudad, convirtiéndolo en uno de los estudios más grandes e importantes de Chimbote y la Región Ancash en los últimos tiempos. A lo largo del libro se expone la realización de las diferentes etapas del estudio y los métodos empleados que permitieron llevar a cabo la investigación subyacente a este texto. En ese sentido, el libro brinda una aproximación general de la problemática actual de las enfermedades no transmisibles en nuestra ciudad, reportando ...

Our aim was to determine the educational gap according to gender, socioeconomic status, and generational group among city adults. The study design was observational and cross-sectional, using data from the 2016-2017 Population Study in Chimbote, Peru. We looked at educational attainment, sex, socioeconomic status and age (for defining generational groups) of 20,005 people aged 22 years and over. Data were summarized in cross-tables and analyzed with a Chi-square test of homogeneity. The results showed that adults presented an educational gap, with a clear disadvantage in the lower socioeconomic level, particularly in the secondary and higher education level groups. Within the socioeconomic levels there are educational inequalities, evidenced in secondary and higher achievement for the poorest women and at the higher level for the younger generations of both socioeconomic levels.

“Background The incidence of kidney cancer has been increasing worldwide, with variable patterns in mortality due to improved diagnostic techniques and increased survival. The mortality rates, geographical distribution and trends of kidney cancer in South America remain poorly explored. This study aims to illustrate mortality by kidney cancer in Peru. Methods A secondary data analysis of the Deceased Registry of the Peruvian Ministry of Health database, from 2008 to 2019 was conducted. Data for kidney cancer deaths were collected from health facilities distributed throughout the country. We estimated age-standardized mortality rates (ASMR) per 100,000 persons and provided an overview of trends from 2008 to 2019. A cluster map shows the relationships among 3 regions. Results A total of 4221 deaths by kidney cancer were reported in Peru between 2008 and 2019. ASMR for Peruvian men ranged...
