Dear Editor:We have read with great interest the article "Intermittent fasting scheme and reduction of anthropometric measurements, lipid profile, blood pressure and cardiovascular risk" published by Dr Javier Wong-Gonzáles et al, in number 1, volume 22 of your magazine; where the purpose of the research focuses on the assessment of the efficacy of intermittent fasting as a strategy for the modification of anthropometric parameters and cardiovascular risk variables; We would like to contribute the importance of defining the times of the day in which the periods of food intake and abstinence are framed during intermittent fasting, since the induced metabolic effects are highly dependent on circadian fluctuations.

“Due to the increase in obesity worldwide, international organizations have promoted the adoption of a healthy lifestyle, as part of which fruit consumption stands out. However, there are controversies regarding the role of fruit consumption in mitigating this disease. The objective of the present study was to analyze the association between fruit intake and body mass index (BMI) and waist circumference (WC) in a representative sample of Peruvians. This is an analytical cross-sectional study. Secondary data analysis was conducted using information from the Demographic and Health Survey of Peru (2019–2021). The outcome variables were BMI and WC. The exploratory variable was fruit intake, which was expressed in three different presentations: portion, salad, and juice. A generalized linear model of the Gaussian family and identity link function were performed to obtain the crude and adj...

El uso de preguntas de opción múltiple constituye un recurso útil, ya que permite evaluar diferentes contenidos a gran escala y con suficiente validez cuando su calidad es adecuada. Sin embargo, la presencia de defectos de redacción es frecuente, lo que junto con características psicométricas inadecuadas altera la validez de las evaluaciones y el proceso mismo de enseñanza-aprendizaje. Además, el proceso de redacción es demandante en tiempo y requiere de entrenamiento. Por estos motivos, la presente investigación tiene como objetivo describir los defectos técnicos de redacción, calidad psicométrica y barreras del docente en la construcción de las preguntas de opción múltiple en la asignatura de Morfofisiología de la carrera de Medicina Humana de una universidad privada de Lima, durante el período 2021-II.El estudio tuvo un enfoque cuantitativo, alcance descriptivo y dis...

To examine factors associated with abdominal obesity among normal-weight individuals from the Demographic and Health Survey of Peru (2018–2021). Cross-sectional analytical study. The outcome variable was abdominal obesity defined according to JIS criteria. Crude (cPR) and adjusted prevalence ratios (aPR) were estimated for the association between sociodemographic and health-related variables and abdominal obesity using the GLM Poisson distribution with robust variance estimates. A total of 32,109 subjects were included. The prevalence of abdominal obesity was 26.7%. The multivariate analysis showed a statistically significant association between abdominal obesity and female sex (aPR: 11.16; 95% CI 10.43–11.94); categorized age 35 to 59 (aPR: 1.71; 95% CI 1.65–1.78); 60 to 69 (aPR: 1.91; 95% CI 1.81–2.02); and 70 or older(aPR: 1.99; 95% CI 1.87–2.10); survey year 2019 (aPR: 1.22...

Objective: To evaluate the relationship between anthropometric profile and serve speed in male Peruvian tennis players. Methods: A quantitative, observational, cross-sectional, and analytical study was conducted with 79 male tennis players from the FiXU sports medical center in Lima, Peru, during 2023 and 2024. Variables such as height, weight, BMI, and limb dimensions were measured. Serve speed was assessed using a calibrated speed gun. Results: The average serve speed was 94.38 km/h (±9.98). The average height of the players was 174.61 cm (±4.17) and the average weight was 72.20 kg (±6.97). Height (r=0.796) and weight (r=0.533) showed significant correlations with serve speed. Weekly playing hours (r=0.611) and years of experience (r=0.435) also showed positive associations. Linear regression identified height (B=1.91, p<0.001), weight (B=0.76, p<0.001), and forearm length (B=...

Background: The association between obesity and depression has been frequently reported. However, it still remains unclear which anthropometric indicators for obesity could be the best measure to explain its linkage with depressive symptoms. Methods: This is a cross-sectional analytical study. Secondary data was analyzed using information from the Demographic and Health Survey of Peru (ENDES in Spanish). Data from the years 2018 to 2021 were reviewed. The outcome of interest was the presence of depressive symptoms, assessed with the Patient Health Questionnaire-9 (PHQ-9). The exposure variable was the presence of obesity, which was evaluated by body mass index (BMI) and abdominal circumference. Crude and adjusted odds ratios (cOR and aOR) were calculated using logistic regression. Both prevalence and association measures were presented with 95% confidence intervals (95% CI). Results: A t...

Introducción: La resistencia a la insulina (RI) es una de las principales causas del desarrollo de patologías crónicas. Es indispensable su detección temprana, por ello es importante estudiar métodos más asequibles y menos costosos como los biomarcadores. Objetivo: Determinar la precisión diagnóstica de once biomarcadores para RI en una muestra de pobladores peruanos. Metodología: Estudio de pruebas diagnósticas. Análisis de base de datos secundario del estudio PERU MIGRANT. Para medir RI se utilizó como referencia la evaluación del modelo homeostático (HOMA-IR) ≥ 2,8. Los biomarcadores se basaron en la ratio de lípidos, los indicadores de lípido visceral, los indicadores con triglicéridos y glucosa (TyG), y los indicadores con cintura abdominal. Para la precisión se utilizó el análisis de la curva de características operativas del receptor y el área bajo la curva...

Introduction: The Mediterranean diet (MedD)is a characteristic eating pattern of the countries of the Mediterranean region. Nonetheless, is unknown its adherence in medical students. We aimed to determine the prevalence of adherence to the Mediterranean diet (AMedD) and associated factors in medical students from Peru. Material and methods: Analytical cross-sectional study carried out by means of a virtual survey. PREDIMED scale was used to evaluate AMedD. The factors assessed were age, sex, academic year, body mass index (BMI), place of lunch consumption, cigarette smoking, and physical activity. Poisson regression with robust variance was used to present it in crude and adjusted prevalence ratios (PRa). Results: High AMedD was present in 38.50%. Statistically significant association was found for sex (PRa: 0.623; 95%CI 0.488-0.796); for overweight (PRa: 0.417; 95%CI 0.270-0.644), obesi...

Introduction: Although body mass index (BMI) and waist circumference (WC) are the most commonly used obesity markers in clinical practice regarding depression, some studies suggest that other obesity markers such as waist-to-height ratio (WHtR), a body shape index (ABSI), body roundness index (BRI), and conicity index (CI) may be more accurate in identifying patients with depression. Objective: To determine the relationship between different markers of obesity and the presence of symptoms of depression. Methods: Analytical cross-sectional study. A secondary analysis was conducted on the Demographic and Family Health Survey (ENDES) from 2018 to 2021. The main variable of the present study was the depression score. Numerical variables were presented as mean and confidence interval at 95 % (CI 95 %). A generalized linear model of the Gaussian family and Identity link function was performed ...

Introduction: Obesity and depression contribute to the global burden of economic cost, morbidity, and mortality. Nevertheless, not all people with obesity develop depression. Objective: To determine the factors associated with depressive symptoms among people aged 15 or older with obesity from the National Demographic and Family Health Survey (ENDES in Spanish 2019–2021). Methods: Cross-sectional analytical study. The outcome of interest was the presence of depressive symptoms, assessed using the Patient Health Questionnaire-9 (PHQ-9). Crude (cPR) and adjusted (aPR) prevalence ratios were estimated using GLM Poisson distribution with robust variance estimates. Results: The prevalence of depression symptoms was 6.97%. In the multivariate analysis, a statistically significant association was found between depressive symptoms and female sex (PRa: 2.59; 95% CI 1.95–3.43); mountain region...
