Irritable Bowel Syndrome in medical students at a Peruvian university: a cross-sectional study.

Background: Irritable Bowel Syndrome has emerged as a significant public health challenge, particularly relevant in medical students due to the high demands of their studies, academic stress, and susceptibility to eating disorders. Nevertheless, conclusive evidence regarding the factors associated with Irritable Bowel Syndrome in the Latin American student population remains limited. The objective of this study was to determine the prevalence and factors associated with Irritable Bowel Syndrome in Human Medicine students at a university in northern Peru. Methods: A cross-sectional analytical study conducted in Lambayeque, northern Peru. With 403 Human Medicine students (66.5% female, 33.5% male). A simple random probabilistic sampling type was used, based on a list of students enrolled. A multivariate analysis was conducted to determine the factors associated using simple and multiple regression models. Generalized Linear Models were applied, using the Poisson distribution family, robust variance, and the academic year as a cluster. Results: The prevalence of Irritable Bowel Syndrome was 16.9% (95% CI: 13.37-20.86). The median age was 21 years, with 66.5% being female. In the multiple regression analysis, Irritable Bowel Syndrome was associated with a higher prevalence of depression (PR: 3.63; 95% CI: 1.26-10.49) and eating disorders (PR: 1.57; 95% CI: 1.01-2.43). For each additional year of age, the prevalence of Irritable Bowel Syndrome decreased by 9% (PR: 0.91; 95% CI: 0.83-0.99). Conclusion: This study reveals that approximately two out of every 10 students exhibit symptoms related to IBS, underscoring its significance in the Human Medicine student population. Furthermore, depression and eating disorders were identified as significant factors associated with IBS in students. Consequently, it is essential to focus efforts on early identification and the implementation of preventive measures to mitigate the development of this pathology, given its substantial prevalence in this context of Human Medicine students.

Prevalence and factors associated with fear of COVID-19 in military personnel during the second epidemic wave in Peru.

Introduction: During the COVID-19 pandemic, the mounting workload and heightened stress may contribute to exacerbated mental health challenges, including an increased fear of COVID-19, among military personnel. Despite the potential influence of these factors, there remains a scarcity of studies addressing mental health issues, particularly the fear of COVID-19, within this specific population. We aimed to determine the prevalence and factors associated with fear of COVID-19 among military members. Methods: A cross-sectional study was conducted between November 2 and 9, 2021, during the second wave of the COVID-19 pandemic in the Lambayeque region, Peru. The outcome variable was fear of COVID-19, assessed using the Fear of COVID-19 Scale. The association with resilience (Connor-Davidson Resilience Scale, abbreviated as CD-RISC), food insecurity (Household Food Insecurity Access Scale, abbreviated as HFIAS), physical activity (International Physical Activity Questionnaire-Short Form, abbreviated as IPAQ-S), eating disorder (Eating Attitudes Test-26, abbreviated as EAT-26), and other socio- demographic variables was assessed. Results: Among the 525 participants, the median age was 22, 95.8% were male, and 19.2% experienced fear of COVID-19. A higher prevalence of fear of COVID-19 was associated with age (PR=1.03; 95% CI: 1.01-1.06), religion (PR=2.05; 95% CI: 1.04-4.05), eating disorder (PR=2.95; 95% CI: 1.99-4.36), and having a relative with mental disorder (PR=2.13; 95% CI: 1.09-4.17). Overweight (PR=0.58; 95% CI: 0.37-0.90) and a high level of resilience (PR=0.63; 95% CI: 0.43-0.93) were associated with a lower prevalence of fear of COVID-19. Discussion: Two out of ten military personnel were afraid of COVID-19. Our results highlight the need for targeted interventions addressing the factors contributing to fear of COVID-19 among military personnel, emphasizing the significance of mental health support and preventive measures within this specific population.

Food insecurity in Piura, Peru, in the context of post-earthquake and the COVID-19 pandemic.

Introduction: Piura, located in a seismic zone, faces challenges related to food security. The aim of this study was to analyze aspects related to food insecurity in the region following the 6.1-magnitude earthquake that occurred in 2021, within the context of the COVID-19 pandemic. Methods: A secondary analysis was performed in 177 people exposed to the earthquake in Piura. Food insecurity was assessed with the Household Food Insecurity Access Scale. Its association with insomnia, resilience, anxiety/depressive symptoms, and general variables were determined using generalized linear models. Results: Food insecurity was observed in 31.1% (95% CI: 24.3-38.4) of participants. This prevalence was higher in people with mild (PR: 1.73, 95% CI: 1.12-2.70) and moderate (PR: 1.55, 95% CI: 1.09-2.22) anxiety symptoms, severe depressive symptoms (PR: 2.74, 95% CI: 1.24-6.03), and previous exposure to the El Niño Phenomenon (PR: 1.72; 95% CI: 1.06-2.81). An income higher than 5000 Peruvian soles (approximately 1300 US dollars) was associated with a lower prevalence of food insecurity (PR: 0.22, 95% CI: 0.13-0.40). Conclusions: Overall, three out of 10 individuals experienced food insecurity after the 2021 earthquake in Piura. Food insecurity may be aggravated by mental disorders, previous exposure to the El Niño phenomenon, and the COVID-19 pandemic. Our study contributes to the field by exploring a range of variables related to food insecurity in a unique context: post-earthquake and during the COVID-19 health emergency in Peru. These findings enhance our understanding of food insecurity at the regional level and highlight the need for preventive food security programs in seismic events.

Association between childhood trauma and mental health disorders in adolescents during the second pandemic wave of COVID-19, Chiclayo-Peru.

Introduction: The COVID-19 pandemic has significantly affected mental health, with children and adolescents being particularly vulnerable. Evidence on the association between childhood trauma and mental health outcomes in schoolchildren during the pandemic is limited. This study aimed to evaluate this relationship in Chiclayo city, northern Peru, during the second wave of COVID-19. Methods: A cross-sectional secondary data study was conducted, measuring childhood trauma using the Marshall's Trauma Scale, depressive symptomatology (PHQ-9), and anxiety symptomatology (GAD-7). Additional variables assessed were alcohol use (AUDIT), resilience (abbreviated CD-RISC), and socio-educational data. Prevalence ratios were estimated using generalized linear models. Results: Among 456 participants, 88.2% were female, with a mean age of 14.5 years (SD: 1.33). Depressive symptomatology prevalence was 76.3% (95%CI: 72.14-80.15) and increased by 23% in schoolchildren with childhood trauma (PR: 1.23; 95%CI: 1.10-1.37). Factors positively associated with depressive symptomatology included increasing age, seeking mental health help during the pandemic, and severe family dysfunction. Anxiety symptomatology prevalence was 62.3% (95%CI: 57.65-66.75) and increased by 55% in schoolchildren with childhood trauma (PR: 1.55; 95%CI: 1.31-1.85). Anxiety symptomatology was positively associated with mild, moderate, and severe family dysfunction. Conclusion: Schoolchildren exposed to childhood trauma are at increased risk for depressive and anxiety symptoms. Monitoring the impact of the COVID-19 pandemic on adolescent mental health is vital. These findings can assist schools in establishing effective measures to prevent mental health outcomes.

Internet addiction and mental health disorders in high school students in a Peruvian region: a cross-sectional study.

OBJECTIVES: To determine the association between internet addiction disorder (IAD) and anxiety and depressive symptomatology in high school students in two private schools in Chiclayo, Peru, during the COVID-19 pandemic. MATERIALS AND METHODS: Analytical cross-sectional investigation of 505 adolescents from two private schools. The dependent variables were anxiety and depressive symptomatology, measured with the Beck Adapted Depression Questionnaire (BDI-IIA) and the Beck Anxiety Inventory (BAI), respectively. The main independent variable was IAD, measured with the Internet Addiction Test instrument(IATI). Prevalence ratios (PR) and 95% confidence intervals (95%CI) were estimated. RESULTS: The average age was 14.16 years and 54.9% were women. 22.2% and 3.2% presented mild and moderate IAD; respectively. 9.3% presented severe anxiety and 34.3% severe depressive symptomatology. In the simple regression, adolescents with mild, moderate and severe IAD presented 19% (PR = 1.19; 95%CI: 1.05-1.35), 25% (PR = 1.25; 95%CI: 1.02-1.53) and 53% (PR = 1.47; 95% CI: 1.47-1.60) higher prevalence of depressive symptomatology; however, this association was not maintained in the multiple model. Anxiety increased 196% in adolescents with severe IAD (PR = 2.96; 95%CI: 1.86-4.71). CONCLUSION: We found that 2, 1, and 3 out of 10 students presented IAD, depressive symptomatology, and anxiety, respectively. We did not find an association between IAD and depressive symptomatology, but we did find an association with anxiety. Among the factors associated with the development of depressive symptomatology were the male sex, the presence of eating disorders, subclinical insomnia, using devices for more than 2 h, and using the Internet for academic activities. About anxiety, the associated factors are the female sex, the presence of eating disorders, subclinical insomnia, and the use of the Internet as social interaction. We recommend implementing counseling programs in view of the imminent introduction of the Internet as a pillar in education.

Depression and anxiety in peruvian military personnel during the pandemic context: a cross-sectional study.

BACKGROUND: During the COVID-19 pandemic, increased workload and stress could have increased mental health problems (anxiety and depression) in military personnel. However, the number of studies in military members is scarce, especially in regard to mental health. The objective of this study was determine the prevalence and factors associated with depression and anxiety in Peruvian military personnel. METHODS: We undertook an analytical cross-sectional study. The survey was distributed face to face between November 02 and 09, 2021, during the second wave of the COVID-19 pandemic among the military personnel. We used some instruments to measure depression (Patient Health Questionnaire, PHQ-9), anxiety (Generalized Anxiety Disorder, GAD-7), insomnia (Insomnia Severity Index, ISI), food insecurity (Household Food Insecurity Access Scale, HFIAS), physical activity (International Physical Activity Questionnaires, IPAQ-S), resilience (abbreviated CD-RISC), and fear of COVID-19 scale. The exclusion criteria included those who did not completely fill out the evaluation instruments. RESULTS: We analyzed the data of 615 military personnel that participated in the survey. Of them, 93.7% were male and the median age was 22 years old. There was a prevalence of 29.9% and 22.0% in regard to depression and anxiety symptoms, respectively. In addition, it was found that being married (PR: 0.63; 95% IC: 0.42-0.94), having a relative with mental health problems (PR: 2.16), having experienced food insecurity (PR: 1.48), insomnia (PR: 2.71), fear of COVID-19 (PR: 1.48), and a high level of resilience (PR: 0.65) were factors associated with depression. In regard to anxiety, the factors associated were working for more than 18 months since the beginning of the COVID-19 pandemic (PR: 0.52), a high level of resilience (PR: 0.50; 95% IC: 0.33-0.77), insomnia (PR: 3.32), fear of COVID-19 (PR: 2.43). CONCLUSION: We found a prevalence of symptoms of depression and anxiety of 29.9% and 22.0%, respectively. In regard to the factors that attenuate depression, we can mention being married and having resilience; and among the aggravating factors, having a relative with mental health problems, food insecurity, insomnia, and fear of COVID-19. Finally, anxiety increased through working time, insomnia, and fear of COVID-19.

Factores tecnológicos-educativos asociados a problemas fisioergonómicos en estudiantes de medicina

Introducción: Existe evidencia sobre el efecto negativo del uso de tecnologías de información y comunicación en estudiantes, sin embargo, poco se conoce sobre problemas fisioergonómicos secundarios a su uso. Objetivo: Identificar los factores tecnológicos-educativos asociados al reporte de 4 problemas fisioergonómicos en estudiantes de medicina. Métodos: Estudio transversal en estudiantes de medicina de 11 países de Latinoamérica y el Caribe. Se utilizó un cuestionario cuyas variables fueron las características socio-educativas y tecnológicas, así como los problemas fisioergonómicos (dolor de cuello, dolor de espalda, ojo seco/rojo y dolor de cabeza). Resultados: De 11 587 estudiantes, 14,5 % reportó presentar 4 problemas fisioergonómicos. La mayoría reportó dolor de cuello (50 %), dolor de espalda (50,5 %) y dolor de cabeza (53,7 %). Tuvieron mayor frecuencia de presentar estos problemas fisioergonómicos las mujeres (RP= 1,06), quienes estudiaron una carrera previa (RP= 1,19), pertenecer a todos los años de estudios (RP= 1,12-1,20), quienes tenían mayor uso de Internet en horas (RP= 1,01) y aquellos que accedían a Twitter en horas de clases (RP= 1,30). La frecuencia de presentar estos problemas disminuyó en quienes tenían menor edad en años (RP= 0,99), procedían de una universidad privada (RP= 0,81), y quienes pertenecían a cualquier grupo extracurricular (RP= 0,67-0,93). Conclusiones: Los factores tecnológicos-educativos asociados al reporte de 4 problemas fisioergonómicos en estudiantes de medicina son ser mujer, tener carrera previa, pertenecer a todos los años de estudios, horas de uso de internet y el acceso a Twitter durante clases.

Introduction: There is evidence on the negative effect of the use of information and communication technologies on students, however, little is known about physio-ergonomic problems secondary to their use. Objective: To identify the technological-educational factors associated with the report of 4 physio-ergonomic problems in medical students. Methods: Cross-sectional study in medical students from 11 countries in Latin America and the Caribbean. A questionnaire was used whose variables were socio-educational and technological characteristics, as well as physio-ergonomic problems (neck pain, back pain, dry/red eye and headache). Results: Of 11 587 students, 14.5% reported presenting 4 physio-ergonomic problems. Most reported neck pain (50%), back pain (50.5%), and headache (53.7%). Women (PR= 1.06), who studied a previous degree (PR= 1.19), who belonged to all years of studies (PR= 1.12-1.20), who had greater use of the Internet, had a higher frequency (in hours) of presenting these physio-ergonomic problems (PR= 1.01) and those who accessed Twitter during school hours (PR= 1.30). They decreased the frequency of presenting these problems, being younger in years (PR= 0.99), coming from a private university (PR= 0.81), and who belonged to any extracurricular group (PR= 0.67-0.93). Conclusions: The technological-educational factors associated with the report of 4 physio-ergonomic problems in medical students were being a woman, having a previous degree, belonging to all the years of study, hours of Internet use and access to Twitter during classes.

Prevalence and Factors Associated with Eating Disorders in Military First Line of Defense against COVID-19: A Cross-Sectional Study during the Second Epidemic Wave in Peru.

Few studies have evaluated eating disorders in military personnel engaged in defense activities during the COVID-19 pandemic. We aimed to determine the prevalence and factors associated with eating disorders in military personnel from Lambayeque, Peru. A secondary data analysis was performed among 510 military personnel during the second epidemic wave of COVID-19 in Peru. We used the Eating Attitudes Test (EAT-26) to assess eating disorders. We explored associations with insomnia, food insecurity, physical activity, resilience, fear to COVID-19, burnout syndrome, anxiety, depression, post-traumatic stress and selected sociodemographic variables. Eating disorders were experienced by 10.2% of participants. A higher prevalence of eating disorders was associated with having 7 to 12 months (PR: 2.97; 95% CI: 1.24-7.11) and 19 months or more (PR: 2.62; 95% CI: 1.11-6.17) working in the first line of defense against COVID-19, fear of COVID-19 (PR: 2.20; 95% CI: 1.26-3.85), burnout syndrome (PR: 3.73; 95% CI: 1.90-7.33) and post-traumatic stress (PR: 2.97; 95% CI: 1.13-7.83). A low prevalence of eating disorders was found in the military personnel. However, prevention of this problem should be focused on at-risk groups that experience mental health burdens.

Association between love breakup and suicidal ideation in Peruvian medical students: a cross-sectional study during the COVID-19 pandemic.

Objective: We aimed to determine the association between a major romantic breakup and suicidal ideation in medical students from three universities in Peru. Methods: A cross-sectional study was conducted during the first pandemic wave in 2021 on medical students from three universities in northern Peru. The outcome was suicidal ideation, measured with question nine of the Patient Health Questionnaire-9 (PHQ-9). Generalized Anxiety Disorder Scale-7 (GAD-7) and Insomnia Severity Index (ISI) were also used to assess mental health symptoms. The exposure was the experience of a major love breakup during the pandemic. In addition, its association with other covariates (age, sex, family members infected with COVID-19, deceased family members with COVID-19, insomnia, and anxiety, among others) was examined. Results and discussions: Out of 370 students, 19.5% reported a major love breakup during the pandemic (95%CI: 15.5-23.8), and 34.3% had suicidal ideation (95%CI: 29.4-39.4). Having a major love breakup was associated with a higher prevalence of suicidal ideation (PR: 1.49, 95%CI: 1.32-1.67, p < 0.001). Moderate insomnia (PR: 2.56, 95%CI: 1.70-3.87, p < 0.001) and anxiety symptoms (PR: 1.94, 1.10-3.44, p = 0.023) were also associated with suicidal ideation. Conclusion: Our study provides evidence of a significant association between a major love breakup and suicidal ideation. This finding emphasizes the need for further research to better understand this association and inform the development of effective suicide prevention policies in medical education.

Factors Associated with Anxiety, Depression, and Stress in Peruvian University Students during the COVID-19 Pandemic.

During the COVID-19 pandemic, university students have adopted measures that completely transformed their educational environment, and this has generated an increase in psychological stress. The present study aimed to identify the factors associated with anxiety, depression, and stress in students at a university in Peru during the COVID-19 pandemic in 2020. We conducted a cross-sectional analytical study in students in Lima, Peru. The DASS-21 scale was used to measure levels of depression, anxiety, and stress and associate it with socio-educational and COVID-19-related variables using generalized linear models with Poisson distribution, log link, and robust variance. Of 400 students surveyed, 19.2%, 23.2% and 17.2% of students presented depression, anxiety, and stress, respectively. The frequency of depression (PR = 0.91, 95%CI: 0.84-0.99), anxiety (PR = 0.90, 95%CI: 0.83-0.99) and stress (PR = 0.92, 95%CI: 0.86-0.99) was lower in women. The students of the engineering and business faculty presented a higher frequency of anxiety (PR = 1.11, 95%CI: 1.00-1.22). There was a greater frequency of presenting anxiety, depression and stress in students who worked in a different area of health or did not work. Our results suggest the importance of promoting mental health awareness campaigns in university students due to the constant academic load they have.

Factors Associated with Knowledge of Evacuation Routes and Having an Emergency Backpack in Individuals Affected by a Major Earthquake in Piura, Peru.

Information on the prevention of earthquakes in Peru, a high-risk country, is still emerging. We determined the frequency and factors associated with knowledge of evacuation routes and the use of emergency backpacks in people affected by a major earthquake. A cross-sectional study using secondary data was conducted from August-December 2021 on people that experienced the 6.1 magnitude earthquake that occurred in Piura, Peru on 30 July 2021. The outcome was self-reported knowledge of evacuation routes and the use of emergency backpacks. The association with self-reported earthquake preparation training, use of sources of information on earthquakes, and sociodemographic variables was investigated. A total of 69.5% of participants knew evacuation routes, and 46.3% had an emergency backpack. A higher frequency of knowledge of evacuation routes was associated with previous training (PR: 1.47; 95% CI: 1.15-1.87), use of the media (PR: 1.35; 95% CI: 1.06-1.72), having received information from the COEN (PR: 1.19; 95% CI: 1.02-1.40), and with a greater number of household members (PR: 1.03; 95% CI: 1.01-1.06). There is a high frequency of knowledge of evacuation routes among participants. However, basic notions of prevention culture are still needed. This research contributes to policy development on earthquake preparation at the community level.

Suicide Risk in Military Personnel during the COVID-19 Health Emergency in a Peruvian Region: A Cross-Sectional Study.

Military personnel represent a frontline group exposed to multiple stressors. These factors have increased during the COVID-19 pandemic, predisposing to the development of suicidal risk (SR). Given the few studies conducted in this population, we evaluated the prevalence of SR and its associated factors during the health emergency. A cross-sectional survey study was conducted in person among 514 participants in Lambayeque, Peru in 2021. The outcome was SR, and the exposures were depression (PHQ-9), anxiety (GAD-7), PTSD (PCL-C), and other sociodemographic variables. The prevalence of SR was 14.0% (95% CI: 11.12-17.31%) and was significantly higher in people with a family history of mental health (PR: 2.16; 95% CI: 1.13-4.15) and in those with moderate clinical insomnia (PR: 2.21; 95% CI: 1.19-4.12). Military personnel with high resilience had a lower prevalence of SR (PR: 0.54, CI: 0.31-0.95). Anxiety was associated with a higher prevalence of SR (PR: 3.27; 95% CI: 1.76-6.10). Our findings show that at least 1 out of 10 military personnel are at risk of suicide. Special attention should be paid to the associated factors to develop interventions and reverse their consequences. These results may be useful in policy implementation and general statistics of SR in the local and regional context.

Association between Working Time and Burnout Syndrome in Peruvian Military during the Second Epidemic Wave of COVID-19.

There is scant evidence on the impact of the COVID-19 pandemic on burnout in front-line military personnel and how working time may influence on this condition. We aimed to determine the association between working time and Burnout syndrome in military personnel. A cross-sectional study was conducted using secondary data among 576 military personnel from Lambayeque, Peru during the second wave of COVID-19 in 2021. We used the Maslach Burnout Inventory instrument to measure Burnout Syndrome. We evaluated its association with work time, measured as the number of months that the military member worked during the pandemic. The prevalence of burnout syndrome was 9%. Of the total sample, 39.1% and 10.3% presented depersonalization and emotional exhaustion, respectively. Military personnel working for more than 18 months had a 104% higher prevalence of Burnout syndrome (PR: 2.04, 95%CI: 1.02-4.10). Exposure to a prolonged work time during the pandemic increased the prevalence of Burnout syndrome in military personnel. This information helps to understand the potential effects of the pandemic on this population and provides insight into the time the military members would need rest to prevent Burnout syndrome.

Simulated tele-management for teaching medical students on primary health care managerial decision making

Introduction: Medical students are poorly prepared in health services management due to the use of traditional teaching methods, developed in theoretical environments with poor active participation. Virtual simulated training is an innovative alternative in the learning process. Objective: This study aimed to determine the knowledge improvement in managerial decision-making amongst medical students at the Universidad Nacional Mayor de San Marcos in Peru, after a virtual simulated training. Methods: A before-after cross-sectional design was undertaken among final year medical students to measure their improvement in management knowledge. The simulation methodology was used as a component of the Medical Externship clinical course in which the administrative dimension of a clinical case such as hypoacusis was considered. Results: Of the 79 participants, 48 (60.8%) were female and the median age was 25 years. There was a median satisfaction level of 3.8 and the performance median score was 17. The median post-test rank scores were higher and statistically significant than pre-test rank scores (p = 0.004); post-test scores for males (p-value = 0.05) and females (p = 0.03) were also statistically higher than pre-test scores. Conclusion: The non-clinical simulation experience improves the knowledge on managerial decision making. It also opens opportunities to work on management issues in clinical courses, providing a comprehensive learning experience. On the other hand, it is an innovative experience where a clinical course adopts a management component.

Introducción: Los estudiantes de medicina están poco preparados en gestión de servicios de salud debido al uso de métodos de enseñanza tradicionales, llevados a cabo en entornos teóricos y poco participativos. La formación virtual simulada es una alternativa innovadora en el proceso de aprendizaje. Objetivo: Determinar la mejora en conocimientos sobre la toma de decisiones gerenciales entre los estudiantes de medicina de la Universidad Nacional Mayor de San Marcos en Perú, tras un entrenamiento simulado virtual. Métodos: Estudio de diseño transversal de antes-después en estudiantes de último año de medicina. La metodología de simulación se utilizó como un componente del curso clínico de externado, en el que se consideró la dimensión administrativa de un caso clínico de hipoacusia. Resultados: De los 79 participantes, 48 (60,8%) eran mujeres y la edad media era de 25 años. La mediana del nivel de satisfacción fue de 3,8 y la mediana del rendimiento fue de 17. La mediana de las puntuaciones del post-test fue mayor y estadísticamente significativa en comparación a la del pre-test (p = 0,004); las puntuaciones post-test fueron más altas que las puntuaciones pre-test para los hombres (p = 0,05) y mujeres (p = 0,03). Conclusiones: La experiencia de simulación no clínica logra una mejora significativa en el conocimiento de los participantes. Además, abre oportunidades para trabajar los temas de gestión en los cursos clínicos, proporcionando una experiencia de aprendizaje integral. Por otro lado, es una experiencia innovadora en la que un curso clínico adopta un componente de gestión.

ABSTRACT Introduction: There is little literature on the association between right bundle branch block and risk factors such as hypertension and diabetes in patients in Latin America and Peru. Objective: To determine the factors associated with right bundle branch block in older adults. Methods: Analytical cross-sectional study completed by 376 elderly patients treated at Almanzor Aguinaga Asenjo Hospital, Lambayeque-Peru. The dependent variable was the presence of right bundle branch block, and the independent variables were age, sex, history of hypertension, and diabetes. Prevalence ratios and 95 % confidence intervals were estimated. Results: Of 376 patients, the majority were male (55,9 %), the mean age was 75,6 years, 11,4 % had a history of hypertension and 9 % were diabetic; 41 % had a diagnosis of right bundle branch block. In simple regression, the frequency of right bundle branch block was 56 % (PR= 1,56; 95 % CI: 1,22-1,99), 65 % (PR=1,65; 95 % CI: 1,26 - 2,15) and 59 % (PR= 1,59; CI 95 %: 1,18 - 2,14) higher in women, hypertensive and diabetics; respectively. In the multiple regression; female sex (PR= 1,53; 95 % CI: 1,21 - 1,95), history of hypertension (PR= 1,55; 95 % CI: 1,21 - 2,00) and diabetes mellitus (PR= 1,49; 95 % CI: 1,12 - 2,00) were positively associated with right bundle branch block. The nested model selected the variables: female sex (PR= 1,54; 95 % CI: 1,21 - 1,96) and history of arterial hypertension (PR= 1,61; 95 % CI: 1,25 - 2,08). Conclusion: Female sex, history of arterial hypertension and diabetes mellitus were positively associated with presenting right bundle branch block in older adults.

Introducción: La pérdida de peso en recién nacidos por cesárea es poco estudiada en Perú. Objetivo: Determinar el punto de corte de la variación de peso en las primeras 24 horas en recién nacidos a término por cesárea para desarrollar pérdida ponderal excesiva. Material y métodos: Se realizó un estudio analítico de prueba diagnóstica. La muestra estuvo conformada por 143 recién nacidos por cesárea sanos a término en Cusco-Perú. Se consideró como variable de interés a la pérdida ponderal excesiva (>10 por ciento) y como variable de exposición a la variación porcentual de peso a las 24 horas. Se establecieron puntos de corte para la pérdida ponderal excesiva por curvas ROC y validación diagnóstica. Resultados: El peso promedio al nacer fue 3262,7 gramos y la variación porcentual de peso a las 24 y 72 horas fue 4,9 por ciento y 8,6 por ciento respectivamente. El área bajo la curva en el grafico ROC fue 64,13 por ciento (IC95 por ciento; 54,03-74,22). El punto de corte para desarrollar pérdida ponderal excesiva a las 72 horas fue 5,47 por ciento (S: 51,28 por ciento; E: 69,23 por ciento; VPP: 38,46 por ciento y VPN: 79,12 por ciento). Por cada punto porcentual incrementado en la variación de peso a las 24 horas, el riesgo de tener pérdida ponderal excesiva se incrementó en 33 por ciento (OR: 1,33; IC95 por ciento 1,11-1,62; p=0,003). Conclusiones: La variación de peso en 5,47 por ciento a las 24 horas puede predecir una pérdida ponderal excesiva en recién nacidos por cesárea en Cusco-Perú(AU)

Introduction: Weight loss in newborns delivered by caesarean section is poorly studied in Peru. Objective: To determine the cut-off point for weight variation in the first 24 hours in term newborns delivered by caesarean section to develop excessive weight loss. Material and methods: An analytical study of diagnostic test was carried out. The sample was composed of 143 healthy babies born by cesarean section in Cusco, Peru. The excessive weight loss (> 10 percent was considered as a variable of interest and the percentage variation in weight at 24 hours was considered as a variable of exposure. Cut-off points were established for excessive weight loss due to ROC curves and diagnostic validation. Results: The average birth weight was 3262.7 grams and the percentage change in weight at 24 and 72 hours was 4.9 percent and 8.6 percent, respectively. The area under the ROC curve was 64.13 percent (95 percent CI; 54.03-74.22). The cut-off point to develop excessive weight loss at 72 hours was 5.47 percent (S: 51.28 percent; E: 69.23 percent; PPV: 38.46 percent and NPV: 79.12 percent). For each percentage point increase in weight change at 24 hours, the risk of having excessive weight loss increased by 33 percent (OR: 1.33; 95 percent CI; 1.11 - 1.62; p = 0.003). Conclusions: The variation in weight by 5.47 percent at 24 hours can predict excessive weight loss in newborns delivered by caesarean section in Cusco, Peru(AU)

Ventilación e intubación respiratoria como factores de riesgo para neumonía en un hospital del tercer nivel / Respiratory ventilation and intubation as risk factors for pneumonia in a tertiary hospital

Introducción: La neumonía asociada a la atención de salud empeora el pronóstico clínico del paciente y genera presión económica sobre los sistemas de salud. Objetivo: Determinar el riesgo de adquirir esta enfermedad en pacientes expuestos a ventilación/intubación y otros factores intrínsecos y extrínsecos. Métodos: Estudio transversal analítico. Población de estudio, pacientes hospitalizados en el Hospital Nacional Adolfo Guevara Velazco del Cusco en el 2017. Se seleccionó una muestra conformada por dos grupos: con diagnóstico de neumonía y sin este. El tamaño de muestra calculado fue de 67 (15 grupo neumonía y 52 grupo no neumonía). El análisis inferencial se realizó en dos etapas, utilizando pruebas de contraste de hipótesis y luego regresión logística. Se recogieron factores intrínsecos y extrínsecos de cada paciente. Resultados: La mayoría de pacientes correspondió al sexo femenino (53,7 por ciento). La mediana de edad fue de 70,6 años. El servicio de unidad de cuidados intensivos tuvo la mayor proporción de casos (42,9 por ciento). Se encontró asociación significativa con el uso de ventilación/ intubación y, además con los factores extrínsecos como traqueostomía, aspiración de secreciones, nutrición enteral y transfusión sanguínea. Ninguno de los factores intrínsecos tuvo asociación significativa en el análisis bivariado. En el análisis de regresión logística los pacientes sometidos a ventilación/intubación tuvieron 5,27 veces el riesgo de contraer neumonía y los pacientes sometidos a transfusión sanguínea tuvieron 12,75 veces el riesgo. Conclusiones: Los pacientes expuestos a ventilación/intubación tuvieron mayor riesgo de desarrollar neumonía asociada a la atención de salud. La transfusión sanguínea también fue un factor asociado(AU)

Introduction: Healthcare-associated pneumonia worsens the clinical prognosis of patients and exerts economic pressure on health systems. Objective: Determine the risk for healthcare-associated pneumonia among patients exposed to ventilation / intubation and other intrinsic and extrinsic factors. Methods: An analytical cross-sectional study was conducted of the patients admitted to Adolfo Guevara Velazco National Hospital in Cusco in the year 2017. A sample was chosen which was composed of two groups: with and without a pneumonia diagnosis. The estimated sample size was 67 (15 in the pneumonia group and 52 in the non-pneumonia group). Inferential analysis was performed along two stages, using hypothesis contrast tests followed by logistic regression. Intrinsic and extrinsic factors were collected for each patient. Results: Most patients were female (53.7 percent). Mean age was 70.6 years. The intensive care unit service had the highest proportion of cases (42.9 percent). A significant association was found with the use of ventilation / intubation, as well as with extrinsic factors such as tracheostomy, secretions aspiration, enteral nutrition and blood transfusion. None of the intrinsic factors had a significant association in the bivariate analysis. In the logistic regression analysis, patients subjected to ventilation / intubation had 5.27 times the risk of contracting pneumonia, whereas patients subjected to blood transfusion had 12.75 times the risk. Conclusions: Patients exposed to ventilation / intubation were at greater risk of developing healthcare-associated pneumonia. Blood transfusion was another associated factor(AU)

ABSTRACT Introduction: Hypertension is a public health problem; sleep disturbances are conditions that predispose to hypertension and aggravate the quality of life of hypertensive patients. Objectives: To describe the characteristics of sleep quality in patients with hypertension in a national hospital in the city of Cusco-Peru, at 3400 meters above sea level (msnm). Material and Methods: A descriptive cross-sectional study was carried out with data of patients with arterial hypertension who attended an outpatient consultation of the cardiology service of a national hospital in Cusco-Peru between August and December 2017. The patients were older than 40 years without comorbidities. To characterize sleep quality, Pittsburg sleep quality index was used with prior informed consent of the patients. Results: A total of 272 patients were studied. The average age was 65 years and the average time of the disease was 8 years. The results show that 75 percent of the patients had poor sleep quality and most of the patients had a sleep duration between 6 and 7 hours. All the patients presented some sleep disturbance and 94.1 percent did not take any medication to sleep. Conclusions: Sleep quality was poor in most of the patients studied. The follow-up of this clinical condition is necessary to evaluate the possible complications that it can cause in the long term(AU)

Coberturas de vacunación en tiempos de COVID-19: Un análisis desde la epidemiología social en la región del Cusco / Vaccination coverage in times of COVID-19: An analysis from social epidemiology in the region of Cusco

Introducción: La pandemia por COVID-19 podría haber afectado la cobertura de vacunación. Objetivo: Estimar las coberturas de vacunación para los años 2018-2020 y analizar las condiciones sociales, económicas y educativas relacionadas a este indicador. Material y Métodos: Estudio epidemiológico social realizado en la región Cusco con reporte de cobertura de vacunación en los años 2018-2020 para el periodo enero ­ mayo y con indicadores económicos y educativos para el 2019. Se estimaron tasas de cobertura de vacunación (pentavalente, antipoliomielítica, antineumocócica y SPR) así como variables de desigualdad. Se expresaron métricas de brecha a través de índices de Kuznets absoluto (ika) y Kuznets relativo (ikr). Resultados: De 112 distritos, las coberturas de vacunación para las 4 vacunas fueron en promedio de 39%, 38% y 24% para el 2018, 2019 y 2020; respectivamente. Las coberturas de vacunación acumulada son similares entre el 2018 y 2019 según estratificador educativo y económico, pero en todos los quintiles del 2020 hubo disminución de las coberturas en un 40% aproximadamente. En los años 2019 y 2020 según escolaridad, las diferencias absolutas y relativas entre los quintiles extremos se invierten, siendo mayor las coberturas en los quintiles con menor escolaridad en comparación con los de mayor escolaridad. Conclusión: Existe disminución de tasas de cobertura de vacunación acumulada para el 2020 y se diferencian según quintiles de escolaridad e ingreso, lo cual se atribuye al estado de emergencia sanitaria debido a COVID-19. Es crítico vigilar las actividades de recuperación de cobertura de vacunación para evitar brotes de enfermedades inmunoprevenibles.

Introduction: The COVID-19 pandemic could have affected vaccination coverage. Objetive: Was to estimate vaccination coverage for the years 2018-2020 and to analyze the social, economic and educational conditions related to this indicator. Material and Methods: Social epidemiological study carried out in the Cusco region with a report of vaccination coverage in the years 2018-2020 for the period January - May and with economic and educational indicators for 2019. Rates of vaccination coverage were estimated (pentavalent, polio, pneumococcal and SPR) as well as inequality variables. Gap metrics were expressed through absolute Kuznets (ika) and relative Kuznets (ikr). Results: Of 112 districts, the vaccination coverage for the 4 vaccines were on average 39%, 38% and 24% for 2018, 2019 and 2020; respectively. Accumulated vaccination coverage is similar between 2018 and 2019 according to educational and economic stratifier, but in all quintiles of 2020 there was a decrease in coverage of approximately 40%. In the years 2019 and 2020 according to schooling, the absolute and relative differences between the extreme quintiles are reversed, with higher coverage in the quintiles with less schooling compared to those with higher schooling. Conclusion: There is a decrease in accumulated vaccination coverage rates for 2020 and they differ according to quintiles of schooling and income, which is attributed to the state of sanitary emergency due to COVID-19. It is critical to monitor recovery vaccination coverage activities to prevent outbreaks of immuno-preventable diseases.
