There is a perception that women visit the general practitioner's office more frequently than men. This study aims to determine the differences between men and women regarding the frequency of healthcare visits to the general medicine service in private medical centers. The sample consisting of 1,144 adults over 18 years of age from the district of Villa El Salvador was collected from July 2020 to July 2021. It was found that 777 (67.9 %) women and 467 (32.1 %) men attended an appointment. Therefore, it is concluded that women visit the general practitioner's office more frequently than men.

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.

Helicobacter pylori infection has a high prevalence in Peru and in the world and is highly associated with gastrointestinal ulcer and gastric cancer. The objective of this research is to determine the prevalence of Helicobacter Pylori in an urban population that attends a medical consultation for the first time due to gastrointestinal symptoms. Descriptive, prospective, cross-sectional study carried out in a population of both sexes and all ages in the district of Villa el Salvador. A 74.3% prevalence of H. Pylori is considered, with a higher prevalence in the intermediate adult and older adult age groups (75%). Likewise, there was a greater attendance to medical consultation on the part of the female sex (n = 208). It is concluded that there is a high prevalence of Helicobacter Pylori infection in patients with gastrointestinal symptoms.

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.

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. Neural networks (multilayer perceptron), multiple linear regression, and Spearman correlation were used to compare the results with the 2021 survey population (population=31,966). Results: The multilayer perceptron had a relative error of 0.17 and 0.12 in women and men, respectively. The regression equation in women was: 8.083 + (0.308*abdominal circumference) + (-0.084*age). In men: 12.132 + (0.338*abdominal circumference) + (-0.166*age). The correlation of both equations was compared with a control group (ENDES-2021), finding very s...
