Background: The Job Demands and Resources (JD-R) model is used to examine predictors of well-being, work engagement, and individual or organizational outcomes. According to the model, work engagement and communication skills play a mediating role between work-family conflict and resilience to job satisfaction in nurses. Methods: A cross-sectional study was conducted considering 431 Peruvian nurses of mean age ( M = 40.31 years; SD = 10.94) ranging from 22 to 68 years working in public hospitals in the Lima region. Data were collected using a self-reported form of the Job Satisfaction Scale, communication skills, work engagement, work-family conflict, and resilience. The theoretical model was evaluated using structural equation modeling (SEM). Results: A theoretical model with adequate fit was obtained [χ 2 (2) = 6.0, P < .001, CFI = 0.995, RMSEA = 0.068, SRMR = 0.015]. Results indicated an inverse relationship between work-family conflict with communication skills (β = −.24, P < .001) and work engagement (β = −.10, P = .003). Likewise, resilience had an influence on communication skills (β = .55, P < .001) and work engagement (β = .33, P < .001). In addition, the model explains 71% of job satisfaction. Also, the results indicate the influence of work-family conflict and resilience through the mediating role of work engagement and work-family conflict on job satisfaction. Conclusions: The model confirmed that work engagement and communication skills are valid moderators to mitigate work-family conflict and strengthen resilience that favors job satisfaction in nurses.

Background: Peru is one of the countries with the highest burden of tuberculosis (TB) and multidrug-resistant tuberculosis (MDR-TB) in the Latin American region and globally. Health education provided by nurses reinforces social support and the quality of patient care allows a greater impact on adherence to TB treatment. Purpose: This study evaluated the mediating effect of treatment education between social support, quality of care, and treatment adherence in TB patients. Methods: A cross-sectional study was carried out considering 162 adult TB patients from four health centers of the public sector located in the center of the city of Lima, Peru. Data were collected on variables, such as social support, quality of care, health education, and adherence to TB treatment. SmartPLS was used for data analysis. Results: The results showed that social support and quality of care significantly influence health education. Likewise, health education mediates social support and quality of care for better adherence to treatment. Conclusion: It is recommended that hospitals take initiatives to provide better health education on TB treatment to ensure better adherence to treatment.

Background. The characterization and evaluation of the nutritional composition of lupine (Lupinus mutabilis) seeds has a long history. However, the determination of the fatty acid profile has only been carried out in a few varieties. Objective. This study determined the fatty acid profile and chemical composition of the oil of six varieties of lupine consumed in Peru. Methods. The extraction of oil from each lupine variety was carried out using the Soxhlet method. Fatty acids, moisture, acidity index, free fatty acids, peroxide value, iodine value, saponification value, and density were determined using official AOAC methods. Results. In general, the average values of saturated fatty acids are lower than those of unsaturated fatty acids. Among the monounsaturated fatty acids (MUFA), oleic acid (C18:1) was the most representative, with values ranging from 41.83% to 54.33%. The “Andenes” variety showed an average oleic acid value of 54.60% compared to the other varieties. The composition of polyunsaturated fatty acids (PUFA) was dominated by linoleic acid (C18:2), and the variety “Cholo fuerte” reported higher values (34.70%) compared to the other varieties. Likewise, the highest average PUFA was 36% and was observed in the “Cholo fuerte” variety. The concentration of linolenic fatty acid (C18:3) ranges from 2.1% for the “Andenes” variety to 2.9% for the common lupine. Additionally, the mean content of linolenic (ω-6) and linoleic (ω-3) acids was 2.33 and 30.89% (13 : 1 ratio), respectively, with the consequent ratio of ω-6/ω-3 fatty acids at the mean level of 0.08. All physicochemical characteristics of lupine seed oil are in accordance with the requirements for edible oils. Conclusion. These findings make the six lupine varieties a new source of promising food components of high nutritional value.

BACKGROUND: Obesity is one of the most important public health problems for university students. The objective of the study was to evaluate the association between body mass index (BMI) and body fat percentage (%BF) with waist circumference (WC) as a cardiometabolic risk factor (CMR) among university students. METHODS: A cross-sectional study was carried out in 2,048 students from a private university located in Lima, Peru. Anthropometric data (weight, height, %BF, and WC) were collected. Chi-square test was used. Association analysis was performed using multiple logistic regression. RESULTS: The findings indicated that 36.9% and 61.1% of men were overweight and had higher %BF, respectively, compared to women. Women (OR, 0.22; 95% CI, 0.17, 0.29), Peruvian students (OR, 0.59; 95% CI, 0.39, 0.90), and students enrolled in the faculty of health sciences (OR = 0.76; 95% CI, 0.62, 0.94) are less likely to manifest CMR. Also, excess body weight (OR, 17.28; 95% CI, 13.21, 22.59) and a high %BF (OR, 4.55; 95% CI, 3.55, 5.84) were strongly associated with CMR. CONCLUSION: CMRs are a public health problem among university students. Therefore, it is important to carry out healthy lifestyle programs to promote better control and prevention, particularly among male students and those who have excess weight and body fat.

The high prevalence of depression among adolescents highlights the need for research aimed at identifying variables with predictive capacity for this condition. In parallel, the scarcity of single-item scales assessing happiness and self-efficacy underscores the importance of developing validated instruments tailored to the Peruvian context. This study aims to examine the predictive roles of perfectionism, self-efficacy, and happiness on depression, as well as the moderating role of sex among Peruvian adolescents. Additionally, it proposes the development of two new instruments: the Javier-Aliaga’s Single-Item Scale of Happiness and the Single-Item Scale of Self-Efficacy. A cross-sectional predictive study was conducted in 380 adolescents from a public school in Lima, Peru, of whom 50.3% were male and Mage = 13.9 (SD = 1.16). The Reynolds Adolescent Depression Scale (RADS-2), the 6-item Perfectionism Scale (EDI-P6), the Javier-Aliaga’s Single-Item Scale of Happiness (JASIHS-v1.0) and the Single-Item Scale of Self-Efficacy (JASISS-v1.0) were used. Predictive analysis was performed using multiple linear regression. The multiple regression analysis showed that Model 2 was the most appropriate (F = 128, p < 0.001, BIC = 2878). The variables perfectionism (β = 0.283, CI [0.215, 0.351], p < 0.001), self-efficacy (β = -0.236, CI [-0.312, -0.161], p < 0.001), happiness (β = -0.386, CI [-0.463, -0.309], p < 0.001), and sex (β = 0.239, CI [0.170, 0.307], p < 0.001) explained 57.3% of the variability in depression (adjusted R2 = 0.573), with happiness being the most influential variable (β = -0.386). The moderation analysis revealed that sex significantly moderated the relationships between perfectionism (b = 0.713, CI [0.166, 1.260], p = 0.011), self-efficacy (b = -3.845, CI [-6.097, -1.593], p = 0.001), and happiness (b = -3.750, CI [-6.134, -1.367], p = 0.002) with depression, with these interactions being stronger in females. Additionally, the JASISS-v1.0 and JASIHS-v1.0 demonstrated excellent content validity (Aiken’s V = 1.00; M = 3.00; SD = 0; 95% CI = 0.70–1.00) and acceptable test–retest reliability (0.71 for the JASISS-v1.0 and 0.76 for the JASIHS-v1.0). The findings highlight the significant influence of perfectionism, self-efficacy, and happiness on depression among Peruvian adolescents, with happiness emerging as the most impactful variable. Moreover, the moderating role of sex suggests that interventions targeting these factors should be designed differently for males and females. Additionally, the development and validation of the JASIHS-v1.0 and the JASISS-v1.0 represent a valuable contribution by providing brief, culturally relevant, and psychometrically sound instruments.

Introduction: University students constantly face a number of health challenges related to an unhealthy diet, characterized by a high intake of saturated fats. Objective: This study aimed to analyze the psychometric properties of the Spanish version of the Block Fat Screener (BFS-E) food frequency questionnaire in a university population. Methods: An observational analytical study of instrumental type was carried out in 5608 Peruvian university students. Based on the Block Fat Screener questionnaire, a back-translation and cultural adaptation process was carried out. The validity of the questionnaire was determined through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), hypothesizing a unidimensional structure. For the determination of reliability, the alpha coefficients were considered; likewise, the ω and H coefficients were used to evaluate the construct. The model explained 63% of the cumulative variance. Results: The CFA confirmed the unidimensionality of the 16-item questionnaire with appropriate goodness-of-fit indicators; therefore, which model of the Peruvian version adequately fits the observed data. The values of the reliability coefficients were higher than 0.90, with ordinal α = 0.94, ω = 0.94, and H = 0.95. Conclusion: The Spanish version of the Block Fat Screener food frequency questionnaire presents adequate psychometric properties and is therefore a valid scale to quickly measure fat intake in university students in a Latin American context.

Background: Anemia and obesity are significant public health challenges among adolescents, often linked to inadequate nutritional knowledge, attitudes, and practices. Educational interventions targeting these factors may play a crucial role in improving adolescent health outcomes. Objective: To determine the impact of a nutrition education program on the levels of knowledge, attitudes, and dietary practices, anthropometric parameters and hemoglobin in Peruvian adolescents. Methods: A pre-experimental study was conducted among Peruvian adolescents between 12 and 18 years of age from an educational institution located in eastern Lima, Peru. Body mass index/age (BMI/age), waist circumference (WC), hemoglobin (Hb) levels, and a self-reported questionnaire were assessed. A nutrition education intervention was conducted for 16 weeks. Results: After the implementation of the program, a significant improvement in knowledge scores (84.4%, p < 0.001), attitudes (59.1%, p < 0.001), and practices (47.7%, p < 0.001) scores was observed. BMI/age scores decreased by 3.1% ( p < 0.001). Similarly, WC scores showed a significant decrease of 1.0% ( p < 0.001). Hb levels increased significantly by 3.25% ( p < 0.001) in women, but not in men. Conclusion: This study showed that nutrition education programs could improve knowledge, attitudes, and dietary practices, BMI/age, WC, and Hb scores in Peruvian adolescents. Keywords: nutrition education, adolescents, anemia, obesity, knowledge, attitudes, dietary practices, body mass index, waist circumference, hemoglobin

Abstract Introduction: Research on religiosity and healthy behaviors has been conducted mainly in developed countries; however, the Latin American context remains unexplored. This study examined the association between religiosity and healthy behaviors in members of the Seventh-day Adventist (SDA) church in different regions of Peru. Methods: A cross-sectional online survey was conducted between June and November 2022. The sample included 767 members of the SDA Church. Information was collected on sociodemographic characteristics and healthy behaviors such as physical activity, adequate sleep, among others. The Duke University Religion Index (DUREL) was used to measure religiosity. Binary logistic regression analyses were used to assess the association between DUREL subscales and healthy behaviors. Women represented 59.7% ( n = 458) of the sample. Results: Higher scores on the religiosity subscales (organized religiosity [ORA], non-ORA, and intrinsic religiosity [IR]) were associated with >20 years of baptism in the SDA Church, receiving a pastoral visit ≥3 times during the past year, performing physical activity 3 to 4 times and ≥5 times/week, sleeping 7 to 9 h/day, attend training on healthy eating, healthy lifestyle seminars, and on 8 health practices promoted by the SDA Church. High IR was less likely in men. Conclusion: The findings of this study show that religiosity has a strong association with healthy behaviors, and that this relationship suggests that religiosity could be considered as a predictor of healthy behaviors.

Background: Body self-perception and dietary self-efficacy may represent an important factor in the prevention of excess body weight. Purpose: This study evaluated body self-perception, dietary self-efficacy, and body mass index (BMI) in the Peruvian population. Methods: A cross-sectional online survey was administered to 190 men and 210 women. Each participant was shown 9 Stunkard anatomical silhouettes corresponding to BMI values. The results obtained were classified as underweight, normal weight, overweight, and obese. The Dieting Self-Efficacy Scale (DIET-SE) was also applied. Chi-square statistic, Kruskal–Wallis, Student t -test, and ANOVA were used to explore differences in means and proportions. Results: Age was significantly higher in those who underestimated their weight and who were dissatisfied with their body (p = 0.000). BMI was higher in men, most were dissatisfied with their body (p< 0.05), and were more likely to underestimate their weight compared to women (p = 0.000). Those participants who were dissatisfied with their body and who underestimated their weight were more likely to have an elevated BMI compared to those who were satisfied and who did not underestimate their weight. All participants had low dietary self-efficacy (LDSE), with a little higher proportion in men compared to women (62.6% vs 61.4%). The majority (45.9%) reported little confidence to resist high-calorie food temptations. More than half of the participants reported body dissatisfaction and LDSE, this was more frequent in men compared to women. Conclusion: It is necessary to develop and implement preventive measures to improve self-perception of the body, taking into account factors such as gender, age, and eating habits. Keywords: dietary self-efficacy, BMI, body self-perception, obesity, Peru

Background: Nutritional status is an indicator of health status and an element of the body's resistance to intercurrent diseases, including COVID-19. Objective: To analyze the nutritional status in hospitalized older adult ICU patients diagnosed with COVID-19. Methods: A cross-sectional study was conducted between April and May 2020. The nutritional status of a group of 83 older adult patients with COVID-19 was determined and compared. The data were analyzed using Chi-square and t-student tests, considering a significance level of 5%. Results: Approximately 42.2% of the patients had excess body weight. Anemia (46.9% vs. 9.8%, p < 0.001) and risk of sarcopenia (45.7% vs. 33.3%, p = 0.011) were higher in women compared to men presenting COVID-19. Furthermore, urea levels were significantly lower in patients with malnutrition compared to those without malnutrition (37.9 mg/dL vs. 44.1 mg/dL, p = 0.020). Similarly, leukocyte concentration was found to be lower in COVID-19 patients with malnutrition 9.6 WBC (x10g ^g/L), p = 0.002. Finally, c-reactive protein (CRP) (37.9 mg/L, p = 0.015), oxaloacetic transaminase (OGT) (61.08 U/L, p = 0.045) and pyruvic transaminase (PGR) (37.14 U/L, p = 0.030) levels were significantly higher in patients with malnutrition compared to those without malnutrition. Conclusion: Nutritional status has a considerable effect on the clinical outcomes of patients with COVID-19. Therefore, further nutritional interventions should be implemented in this regard, paying special attention to both the elderly population.
