Network analysis of anxiety and depressive symptoms during the COVID-19 pandemic in older adults in the United Kingdom.

The health crisis caused by COVID-19 in the United Kingdom and the confinement measures that were subsequently implemented had unprecedented effects on the mental health of older adults, leading to the emergence and exacerbation of different comorbid symptoms including depression and anxiety. This study examined and compared depression and anxiety symptom networks in two specific quarantine periods (June-July and November-December) in the older adult population in the United Kingdom. We used the database of the English Longitudinal Study of Aging COVID-19 Substudy, consisting of 5797 participants in the first stage (54% women) and 6512 participants in the second stage (56% women), all over 50 years of age. The symptoms with the highest centrality in both times were: "Nervousness (A1)" and "Inability to relax (A4)" in expected influence and predictability, and "depressed mood (D1"; bridging expected influence). The latter measure along with "Irritability (A6)" overlapped in both depression and anxiety clusters in both networks. In addition, a the cross-lagged panel network model was examined in which a more significant influence on the direction of the symptom "Nervousness (A1)" by the depressive symptoms of "Anhedonia (D6)", "Hopelessness (D7)", and "Sleep problems (D3)" was observed; the latter measure has the highest predictive capability of the network. The results report which symptoms had a higher degree of centrality and transdiagnostic overlap in the cross-sectional networks (invariants) and the cross-lagged panel network model of anxious and depressive symptomatology.

Intake of foods high in saturated fats, vegetarian dietary pattern, and sociodemographic characteristics associated with body weight in Peruvian university students.

Background: The prevalence of obesity continues to increase among university students and the general population. Consumption of a diet high in saturated fats could be one of the risk factors. Objective: The consumption of foods high in saturated fats, the vegetarian diet pattern, and sociodemographic characteristics associated with excess body weight (overweight/obesity) were evaluated in Peruvian university students. Methods: A cross-sectional study was carried out selecting 5,608 Peruvian university students through no probabilistic convenience sampling. The survey was carried out during the months of February and April 2022. The Chi-square test and binary logistic regression analysis were used to evaluate the association between diet (saturated fats intake and dietary pattern) and sociodemographic factors with excess body weight in a cross-sectional analysis. Results: It was observed that students who reported high consumption of foods high in saturated fats (ORB = 1.14) and those who had a non-vegetarian dietary pattern (ORB = 2.76) were found to be more likely to have excess body weight. On the contrary, students who reported adherence to the vegetarian diet pattern for more than 5 years were less likely to be overweight or obese (ORB = 0.84). Being ≥26 years of age (ORB = 3.28), living in urban areas (ORB = 1.68) and coastal areas of the country (ORB = 1.17), and enrolled in the engineering faculty (ORB = 1.19), were significantly associated with excess body weight. Conclusion: The findings of the current study evidenced several factors associated with excess body weight in university students. Therefore, it is necessary to promote and implement healthy lifestyle programs, considering sociodemographic and dietary aspects such as age and dietary intake to control and prevent obesity in university students.

Impact of a Nutrition Education Intervention on Knowledge, Healthy Eating Index, and Biochemical Profile in a Rural Community in Peru.

Background: Non-communicable diseases in adults and anemia in children represent a major global public health problem, with multiple causes including poor dietary quality. However, nutrition education interventions can empower individuals to make appropriate dietary changes. Objective: To evaluate the impact of a nutritional education intervention on nutrition knowledge (NK), healthy eating index (HEI), and biochemical profile in families in the community in Peru. Methods: A pre-experimental study was conducted in the community of Sinchicuy, located on the banks of the Amazon River, Iquitos, Peru. Nutrition education was provided over a 16-week period to a total of 61 heads of household (23 children under 5 years of age and 23 older adults). Fasting glucose and hemoglobin (Hb) concentration analyses were also carried out before and after the intervention. Results: After the intervention, a significant improvement in the NK score was observed, increasing by 90% (p < 0.001). Additionally, the average HEI scores experienced a significant increase, rising by approximately 11.4% (p < 0.001). In children under 5 years of age, the Hb level showed a significant increase of 5.1% (p = 0.017). However, no statistically significant difference in glucose concentration was observed in older adults after the intervention. Conclusion: The findings of this study indicated a positive impact on NK, HEI, and Hb in heads of households, older adults, and children under five in a rural community where there is limited access to basic services.

Body mass index and healthy lifestyle practices among Peruvian university students: a comparative study among academic discipline.

Background: Excess body weight and an unhealthy lifestyle are a risk factor for noncommunicable diseases. University students are susceptible to unhealthy habits and obesity. This study compared body mass index (BMI) and healthy lifestyle practices among university students from four academic disciplines: Health Sciences, Business Sciences, Human Sciences and Education, and Engineering/Architecture. Methods: A cross-sectional study was carried out using a sample of 6,642 university students selected by non-probability convenience sampling. The Diet and Healthy Lifestyle Scale (DEVS), the Peruvian validation of the Vegetarian Lifestyle Index (VLI), was used to assess healthy lifestyle practices. Results: Students in the areas of Business Sciences and Engineering/Architecture had a higher BMI than their peers in Health Sciences (B = 0.35, 95% CI: 0.15-0.56 and 0.32, 95% CI: 0.13-0.52; p = 0.001). Additionally, these students tended to adopt less healthy lifestyle (B = -0.11, 95% CI: -0.20 to -0.01 and -0.09, 95% CI: -0.18 to -0.00; p < 0.05) compared to those in Health Sciences. Conclusion: Although students of Health Sciences and Human Sciences and Education exhibited healthy lifestyle patterns, there is a clear need to improve eating and living habits in general among the university population to mitigate the risk factors associated with non-communicable diseases.

Analysis of adherence to a healthy lifestyle among vegetarian and non-vegetarian Peruvian university students: A cross-sectional survey.

BACKGROUND: Evidence shows that a healthy lifestyle can promote physical and mental well-being in the general population. However, there are few studies that assess the adherence to a healthy lifestyle in vegetarian and non-vegetarian university students. The purpose of this study was to evaluate the differences in adherence to a healthy lifestyle between vegetarian and non-vegetarian university students in Peru. METHODS: A cross-sectional study was carried out considering data from 6,846 students selected by non-probabilistic convenience sampling. The Diet and Healthy Lifestyle Scale (DEVS), the Peruvian validation of the Vegetarian Lifestyle Index (VLI), was used. In addition, sociodemographic and anthropometric data such as weight and height were collected. Body mass index (BMI) was also calculated. RESULTS: Semi-vegetarian and vegetarian students had a high healthy lifestyle score compared to non-vegetarians. In addition, vegetarian diets showed a significantly higher proportion among students with a lower BMI (normal and underweight). Students with excess body weight (overweight and obesity) were less likely to report healthy lifestyle. In the overall population analyzed, it was observed that the levels of health and lifestyle behaviors, such as daily exercise and sunlight exposure, were mostly moderate and low. Additionally, sweets intake was high, while healthy food consumption such as fruits, vegetables, legumes, and whole grains was low. CONCLUSION: The current findings show that although vegetarians had better adherence to a healthy lifestyle, interventions in the university setting are needed to improve healthy lifestyle in university students.

A Network Analysis Approach to Understanding Centrality and Overlap of 21 Dark Triad Items in Adults of 10 Countries.

Background: Previous research has suggested that manipulation and callousness are central to Dark Triad traits, but it has not identified which specific manifestations are expressed across various countries. Objective: This study aimed to identify the core and overlapping manifestations of Dark Triad traits across 10 countries. Methods: We used the Short Dark Triad (SD3) scale and assessed a sample of 8093 participants (59.7% women, M(age) = 32.68 years). For graphical representation, the spinglass algorithm was applied to understand the cluster distribution among Machiavellianism, psychopathy, and subclinical narcissism traits. Centrality indices were used to identify the most influential items, and the clique-percolation algorithm was employed to detect shared attributes among multiple Dark Triad items. Results: Straightforward SD3-21 items demonstrated better interpretability as aversive traits within the broader system. Items with higher centrality values were those related to short-term verbal manipulation from the psychopathy domain, clever manipulation, strategic revenge-seeking from Machiavellianism, and narcissistic motivations for connecting with significant individuals. The most predicted items were linked to planned revenge, using information against others from Machiavellianism, short-term psychopathic verbal manipulation, and narcissistic belief of specialness based on external validation. Items like short-term verbal manipulation had overlaps with both psychopathy and narcissism clusters, while clever manipulation overlapped with Machiavellianism and psychopathy. Conclusion: This cross-cultural study highlights the central role of verbal manipulation within the Dark Triad traits, along with identifying overlapping items among traits measured using straightforward SD3 scale items. In line with our findings, future research that incorporates a wide range of cultural contexts is encouraged to establish the consistency of these findings with the SD3 Scale or alternative measures.

Evidence of validity and reliability of the environmental action scale in Peruvian university students.

Background: The environmental action scale is used to measure the degree of participation in collective environmental actions and has been shown to have adequate psychometric properties in developed countries. However, there are still no studies that have evaluated its performance in the Peruvian population. Methods: In this instrumental study, the environmental action scale (EAS) was translated, adapted, and validated. The EAS was administered to 352 university students between 18 and 35 years of age (Mage = 23.37, SD = 2.57) from different cities in Peru. A validity analysis was performed using two sources of evidence: content validity and internal structure, carrying out an exploratory factor analysis (EFA) and a confirmatory factor analysis (CFA). Results: The structure of the scale has been organized into three oblique factors. The findings confirmed the reliability and validity of the three dimensions of the EAS. Conclusion: Therefore, this scale is considered a valid option for assessing environmental action.

Structure and factorial invariance of a brief version of the Eating Attitudes Test in Peruvian university students.

Background: University students often experience significant changes in their eating habits, which can increase the risk of developing eating disorders (ED). This situation calls for the creation of brief assessment tools to identify college students who may be most at risk. The aim of the study was to determine the psychometric properties of the Eating Attitudes Test-8 (EAT-8) in a Peruvian university population; additionally, the possible differences in the scores of the instrument according to sociodemographic variables, such as gender and age, were examined. Methods: A psychometric study was conducted on 610 participants (M = 24.3, SD = 2.16, and 61.5% female), aged 19 to 31 years, belonging to four universities of different professional careers. Results: The unidimensional eight-item model was found to have fit indices that confirm acceptable factorial validity (X2/df = 3.23, CFI = 0.984, TLI = 0.977, RMSEA = 0.061, SRMR = 0.049) and an internal consistency of 0.833 for the Cronbach's alpha coefficient and 0.838 for the McDonald's omega coefficient. In addition, the EAT-8 was reported to be invariant according to gender and age; likewise, there were no significant differences in the age and gender categories. Conclusion: The EAT-8 has solid psychometric properties, including validity, reliability, and invariance, in the Peruvian university population, which supports its ability to assess the risk of developing ED in this specific group.

Influence of servant leadership on the life satisfaction of basic education teachers: the mediating role of satisfaction with job resources.

Background: Life satisfaction is essential for teachers' work performance and student learning. Additionally, servant leadership has been shown to be one of the best leadership practices as it promotes employee well-being and satisfaction. Moreover, satisfaction with job resources acts as a mediator in the relationship between servant leadership and life satisfaction by influencing individual and collective performance in the organization. Objective: This research aimed to evaluate the mediating role of satisfaction with job resources in the relationship between servant leadership and life satisfaction. Methods: The study was cross-sectional and explanatory. 620 teachers aged between 20 and 62 years (M = 35 and SD = 9.49) participated in the study. Structural Equation Modeling (SEM) was used to measure life satisfaction, service leadership, and job resource satisfaction through the use of questionnaires. Results: The results indicated that the model obtained an adequate fit, χ2 = 2,658, df = 551, p < 0.001, CFI = 0.941, TLI = 0.936, RMSEA = 0.079, SRMR = 0.070. The results confirm the positive influence of leadership on satisfaction with resources and life satisfaction. Additionally, a positive influence of satisfaction with job resources on life satisfaction was observed. Moreover, the mediation of job resources in servant leadership and life satisfaction was confirmed. Conclusion: Servant leadership, supported by satisfaction with job resources, can reduce effort and associated costs, stimulate personal growth and learning, and improve the well-being of teachers.

Validation of the Working Alliance Inventory- Short Form for Patient (WAI-S-P) in Peruvian Adults.

Background: Although the importance of the therapeutic alliance in the treatment process and health outcomes is recognized, so far, there has been no evaluation in the Peruvian context that considers possible individual differences that could influence this assessment. Purpose: This study assessed the psychometric properties of the WAI-S-P in a sample of individuals from Peru who are receiving psychological therapy. Furthermore, a network analysis was conducted to investigate the direct relationships between the therapeutic alliance and several relevant sociodemographic variables. Methods: The short version of the Working Alliance Inventory was used in a sample of 241 participants (Mage=32.58, SD=12.67) that had attended less than 6 sessions. Three models were considered, including a three-factor and a two-factor correlated model, as well as a bifactor model. In addition, a network of partial associations was created including the overall therapeutic alliance, sex, age, and number of psychotherapeutic sessions. Results: The bifactor model, with an overall therapeutic alliance factor and two specific factors ("contact" and "contract"), better fit the data. Invariance of the structure by sex and age showed equitable measurement. On the other hand, network analysis revealed a positive correlation between total session attendance and therapeutic alliance. Men reported higher therapeutic alliance, while women had higher total session attendance. Conclusion: The results of this study suggest that the therapeutic alliance is better represented by a bifactor model and demonstrates invariance across sex and age in Peruvian adults. Additionally, findings indicate that differences in life experiences and the sex of patients may need to be verified in future studies to better understand nuanced needs in forming therapeutic alliances at least in the early stages of session attendance.

Network Analysis of Dark Triad Traits and Emotional Intelligence in Peruvian Adults.

Background: The study of Dark Triad traits and emotional variables has been conducted in numerous regions; however, there is a lack of research focusing on Latin American samples and considering variables such as sex and age. Incorporating these variables could enhance our understanding of underlying aversive patterns. Purpose: This study aimed to analyze the associations between Dark Triad traits and emotional intelligence in Peruvian adults. Methods: Data were collected in 2021 and 272 adults (M=31.8 years, 68% female) participated through online surveys via non-probability purposive sampling. Dirty Dozen and Trait Meta-Mood Scales were used. Two partial correlation network models were applied between the study variables with and without controlling for gender and age. Bridge-expected influence and predictability analysis were calculated to find interconnected traits and higher connections, respectively. Results: Subclinical psychopathy primarily showed negative associations with emotional clarity (r=-0.17), followed by emotional attention (r=-0.08) and emotional repair in networks with and without age and gender variables. Machiavellianism consistently displayed a negative association with emotional repair (r=-0.13) in both estimated networks. Conversely, subclinical narcissism exhibited a positive association solely with emotional attention (r=0.15). Furthermore, younger age was linked to higher Machiavellianism (r=-0.23), females showed higher emotional attention (r=0.11), and narcissism connected intrapersonal emotional domains with Dark Traits (bridge expected influence >1.25) while Machiavellianism exhibited greater predictability (r2>0.45) due to reinforcement by other Dark Traits. Conclusion: This study revealed negative connections between the Dark Triad and emotional intelligence traits, except for narcissism, which was positively associated with emotional attention and functioned as a "bridge" between all traits. However, relying solely on this single positive emotional aspect of narcissism may not be adequate to characterize it as possessing fully adaptive emotional traits. Findings suggest that detailed aspects of emotional intelligence and sociodemographic factors can provide valuable insights into the complex nature of aversive patterns and their broader impact on society.

The relationship between positive and negative stress and posttraumatic growth in university students: the mediating role of resilience.

BACKGROUND: Information on understanding the mediating role of resilience in the relationship between posttraumatic growth (PTG) and positive and negative stress among students is limited. The objective of this research was to evaluate the mediating role of resilience in the relationship between positive and negative stress and PTG in university students. METHODS: The research was carried out using an associative strategy with an empirical approach and explanatory design, with a sample of 507 participants whose average age was 22.38 years ([Formula: see text]= 3.758), the sample was mostly composed of women (70.4%). RESULTS: The results allow us to describe that resilience plays a complete mediating role in the relationship between negative stress and PTG. On the other hand, mediation was partial when resilience mediated the relationship between positive stress and PTG. In addition, multigroup invariance analyses according to gender and geographic context show that there is no difference in males, females, and the region where they reside. CONCLUSION: In conclusion, the hypothesis that resilience fulfills the mediating function is ratified.

Bifactor SEM and MIRT Structure of a 12-Item Human Immunodeficiency Virus Stigma Scale in Peruvian Adults.

BACKGROUND: The stigma associated with human immunodeficiency virus (HIV) can lead to prejudice and discrimination against people who have been infected by this virus, consequently, it is important to have a validated tool to measure this phenomenon. However, there is only 1 national precedent that has validated the scores of this instrument in its 21-item version. Therefore, this study examined the bifactor structural equation method (SEM) and multidimensional item response theory (MIRT) structure of a 12-item human immunodeficiency virus stigma scale in Peruvian adults. METHODS: We evaluated 342 patients (57.6% female and 42.45% male) diagnosed with HIV receiving highly active antiretroviral therapy (HAART) from a hospital located in East Lima, aged 18 to 45 years (M = 31.4, SD = 9.79). A SEM was used to test 2 measurement models, a 4-factor correlated oblique model and a bifactor model due to high interfactor relationships. RESULTS: Acceptable fit indices were identified for the oblique model (χ2/df = 1.26, SRMR = 0.044, RMSEA [90% CI] = 0.028 [0.000-0.047], CFI = 0.996, TLI = 0.994). In the same way, similar results were evident for the bifactor model (χ2/df = 1.14, SRMR = 0.039, RMSEA [90% CI] = 0.020 [0.000-0.044], CFI = 0.998, TLI = 0.997), however, in the latter it showed a greater explanation for the unidimensional model (H = 0.87, PUC = 0.82, LCA = 0.70), which was also evidenced by the bifactor MIRT analysis. CONCLUSION: It is concluded that the 12-item HIV Stigma Scale meets the psychometric properties of internal structure and unifactorial reliability.

Healthy Habits Factors and Stress Associated with Health-Related Quality of Life in a Peruvian Adult Population: A Cross-Sectional Study.

Background: Healthy habits contribute to the prevention of diseases and, therefore, improve the health-related quality of life of people. However, stress is one of the main risk factors associated with serious health problems in the individual. Therefore, the literature suggests a relationship between healthy habits, stress, and health-related quality of life. Objective: To assess the factors of healthy habits and stress associated with health-related quality of life in a Peruvian adult population. Methods: A cross-sectional study was conducted with a sample of 540 Peruvian citizens aged between 18 and 60 years. A questionnaire was applied on the Google Forms platform to be completed online, using the "Healthy Lifestyle Questionnaire" and the PSS-4 to assess healthy habits and stress, respectively. Health-related quality of life was evaluated using the EuroQol-5D. Results: In the multivariate analysis, stress was the most associated factor with quality of life. Physical activity, drug consumption, tobacco consumption, rest habits, and a balanced diet were healthy habits associated with quality of life. Conclusion: Physical activity, rest habits, and a balanced diet improve health-related quality of life, while drug or tobacco consumption and stress are associated with a lower health-related quality of life.

Sociodemographic Factors, Mental Health, and Emotional Eating Associated With Concern for COVID-19 Contagion in Nurses: A Cross-Sectional Study.

OBJECTIVE: To determine the association between sociodemographic factors, stress, depression and anxiety, emotional eating, and concern about COVID-19 contagion in first and second-line Peruvian nurses. METHODOLOGY: The study was cross-sectional and conducted with 500 Peruvian nurses of both sexes, over 18 years of age. Validated questionnaires were used to measure sociodemographic aspects, concern about COVID-19, generalized anxiety, depression, self-perceived stress, and emotional eating. Multiple linear regression analysis was performed to analyze the factors affecting concern about COVID-19 contagion. RESULTS: The multiple linear regression analysis showed that stress, being between the ages of 18 and 29 years, being male, being from the coastal region or the jungle region, having a bachelor's degree, severe anxiety, and severe depression were associated with higher concern about COVID-19. On the other hand, having more than 5 to 10 years of experience and more than 10 years of experience, low emotional eating, and non-emotional eating were negatively associated with concern. This model explained 44.05% of the variability among the participating nurses. CONCLUSION: These findings provide resources for future research on the comprehensive well-being of nursing staff by exploring various sociodemographic aspects and mental conditions associated with greater concern about COVID-19. Meanwhile, years of experience and emotional eating behavior were associated with lower concern about COVID-19. Future studies could incorporate this information to preserve the mental and physical health of nurses in the face of potential occupational threats.

Psychometric Properties of the Peruvian Version of the MOS Scale for Social Support in Cancer Patients and Convergent Network with Quality of Life.

Introduction: One of the key psychosocial factors that impact mental and emotional health is social support. While much research has been conducted on the role of social support in the lives of cancer patients, there is a lack of studies that consider populations who need specific tools to assess this concept. Purpose: The aim of this study was to evaluate the psychometric properties of the MOS Social Support Scale (1991) in 499 Peruvian cancer patients between the ages of 18 and 87 (M= 46.30, SD = 15.747). Methods: In this study, three models of the MOS were analyzed based on 19-item versions (four factor, second order and bifactor model). Results: The results showed a better psychometric fit in the 19-item bifactor model with optimal fit indices through the structural equation method (SB-χ2/df = 1.94, CFI = 0.966, TLI= 0.955, SRMR = 0.038 and RMSEA = 0.058). Additionally, there was evidence of configural, metric and scalar invariance with this instrument according to the gender of the surveyed cancer patients. Convergent validity using a network analysis approach revealed positive associations between social support dimensions and quality of life. Conclusion: Emotional support and positive interactions dimensions were found to be important interconnections in the overall network, as indicated by their greater centralities. Therefore, this instrument could be suggested as a reliable way to evaluate cancer patients and their perceived support.

Association between frequency of breakfast consumption and cardiometabolic risk in Peruvian university teachers, 2019-2020.

Background: Although the relationship between health status and dietary intake has been extensively studied in the general population, there is a lack of research that has specifically examined the association between frequency of breakfast consumption and cardiometabolic risk in university teachers. Objective: To determine the association between the frequency of breakfast consumption and cardiometabolic risk in university teachers. Methods: A cross-sectional study was conducted in 176 teachers from a private university located in the eastern region of Lima, Peru (Mage: 37.0 years; SD: 0.8, range: 24-59 years). The study was conducted during the period from December 2019 to February 2020. Information was collected on anthropometric and biochemical parameters and frequency of breakfast consumption. Multinomial logistic regression models were used to explore the association between frequency of breakfast with sociodemographic, anthropometric, and biochemical variables. Results: The highest prevalence of excess body weight (44.4%) was observed in those who consumed breakfast 0 to 2 days/week, but without statistical differences. Those who reported Low-density lipoprotein cholesterol (LDL-C) < 160 mg/dL were 77% less likely to fall into the 3-5 day/week breakfast frequency category than those who reported a regular frequency of breakfast (6 to 7 days/week) (Adjusted OR = 0.23, 95% CI 0.08 to 0.73; p < 0.05). In addition, teachers who reported a breakfast frequency of 3 to 5 days/week were 83% more likely to have a glucose concentration < 110 mg/dL compared to those who consumed breakfast of 6 to 7 days/week (Adjusted OR = 0.17, 95% CI 0.04 to 0.75; p < 0.05). Conclusion: Skipping breakfast for an extended period of time can have detrimental effects on cardiometabolic health. Promoting the benefits of breakfast could be a health message of great public health interest.

Structure and factorial invariance of the Grit-Original scale and convergent validity of the network with job satisfaction and happiness.

Background: The concept of Grit refers to a person's ability to maintain perseverance and passion in the pursuit of long-term objectives. However, research on the applicability of the Grit-Original scale (Grit-O) in the Latin American context is limited. Objective: This instrumental design study aimed to analyze the structure of this scale and its factorial invariance in relation to gender, as well as to examine its convergent validity with job satisfaction and happiness. Methods: A sample of 364 Peruvian workers that were selected through non-probabilistic convenience sampling in 2021. Results: The results of the confirmatory factor analysis showed that the two-dimensional structure of 12 items presented adequate goodness-of-fit indices. Additionally, the instrument is invariant between men and women. Likewise, the convergent relationship between the Grit scale, job satisfaction, and happiness variables was confirmed, which supports the validity of the instrument in the study context. Conclusion: The findings of the study confirm that the GRIT-O is a measure with adequate psychometric properties in the Peruvian context.

Gender network analysis of the Eating Disorder Examination-Questionnaire (EDE-Q7) in Peruvian adults / Análisis de red de género del Eating Disorder Examination-Questionnaire (EDE-Q7) en adultos peruanos

Background: network assessment of eating disorder (ED)-related symptomatology from a gender perspective is an important topic of study; however, there is limited research in the Latin American context. Objective: this study aimed to explore the patterns of association of the components of the Eating Disorder Examination-Questionnaire (EDE-Q7) according to gender, using two simultaneous network models in 890 Peruvian adults (63.51 % were women; mean age: 26.40). Methods: two graphs considering the gender factor were made using the R package qgrap and the merged LASSO graph. Results: higher network centrality measures were obtained for items related to body image dissatisfaction and overvaluation in women; while in the men's network, the items of food restriction and overestimation of weight were the most central symptoms. Conclusion: both network models were invariant and showed no significant differences in both structure and connections.(AU)

Introducción: la evaluación de redes de la sintomatología relacionada con los trastornos alimentarios (TA) desde el punto de vista del géneroes un tema importante de estudio; sin embargo, existen pocas investigaciones en el contexto latinoamericano.Objetivo: el objetivo de este estudio fue explorar los patrones de asociación de los componentes del Eating Disorder Examination-Questionnaire(EDE-Q7) según el sexo mediante dos modelos de red simultánea en 890 adultos peruanos (63,51 % de mujeres; edad promedio: 26,40 años).Métodos: se realizaron dos gráficos considerando el factor género utilizando el paquete R qgrap y el gráfico LASSO fusionado.Resultados: se obtuvieron medidas de centralidad de red más altas para los ítems relacionados con la insatisfacción y la sobrevaloración dela imagen corporal en las mujeres; mientras que, en la red de los hombres, los ítems de restricción alimentaria y sobrevaloración del peso eranlos síntomas más centrales.Conclusión: ambos modelos de red resultaron invariables y no mostraron diferencias significativas a nivel de estructura y conexiones.(AU)
