Objective: To determine the sociodemographic risk factors associated with suicidal risk in the Peruvian population. Methods: An analytical and cross-sectional study was performed based on data from 24,000 violent deaths registered at the national death system (SINADEF) in 2021.

La medición de los niveles de hemoglobina glicada (HbA1c) es el método de laboratorio más utilizado en el seguimiento y monitorización de la glucemia media estimada de los últimos 3 a 4 meses. El objetivo de la investigación es determinar el nivel de correlación entre hemoglobina glicosilada y glucemia basal en pacientes diabéticos en un centro médico de Lima, Perú. Estudio descriptivo correlacional de corte transversal de una población de 172 pacientes con edad igual o mayor de 39 años diagnosticados y en tratamiento por diabetes mellitus (DM), se encontró que existe una correlación moderada y positiva de 0,50. Se concluye que los niveles de hemoglobina glicada están moderamente relacionados con los niveles de glucosa basal por lo que se recomienda valorar ambos exámenes de laboratorio por separado y en el contexto individualizado de cada paciente.

Objective: To develop a simplified anthropometric equation of total body water based on abdominal circumference and age based on Watson's formula. Material and methods: Analytical and cross-sectional study, based on data from the 2022 national demographic health survey (population=32,066). The variables were: total body water, age, sex, abdominal perimeter.
