Introducción: Los estudiantes universitarios se han visto obligados a cambiar sus hábitos debido a la cuarentena por la pandemia COVID-19. Objetivo: Desarrollar una escala de validación para conocer los cambios en los estilos de vida durante la cuarentena en estudiantes universitarios de Lima, Perú. Métodos: Estudio transversal, observacional, analítico. Se encuestaron a 549 universitarios de medicina humana y psicología de dos universidades privadas de Lima de forma virtual. Se realizó la validez de constructo, la fiabilidad y los rangos/categorías para calificar el estilo de vida. Resultados: La escala final quedó conformada por 25 reactivos. La prueba de esfericidad de Bartlett fue significativa (3514,19, gl= 300, p<0,001) y el indicador de adecuación del tamaño de muestra Kaiser-Meyer-Olkin fue adecuado (0,845). Las cuatro áreas temáticas fueron cambios con respecto a 1) Hábitos alimenticios; 2) Hábitos nocivos; 3) Actividad física; y 4) Uso de medios de comunicación. Al ser una escala de medición ordinal tipo Likert, se procedió a confirmar los resultados a través del programa Factor Analisys obteniendo un KMO de 0.80 (confiable) y la prueba de esfericidad de Bartlett significativa (5528,8; p<0,001; gl=300), confirmando la existencia de 7 componentes que explican el 63% de la varianza. Conclusión: Esta escala reúne las propiedades psicométricas para ser considerado un instrumento útil, valido y fiable para medir dichos cambios en estudiantes de carreras de ciencias de la salud, siendo necesario validarlo en forma prospectiva en otras carreras y países. Palabras clave: Estilo de vida; Estudiantes; Estudio de validación (fuente: DeCS BIREME).

Introduction: Given the high consumption of salt in the population, the need arises to have a validated tool that measures the knowledge, attitudes and practices of salt consumption (CAP-salt). Objective: To validate the questionnaire on CAP-salt. Methods: Psychometric study of content validity through expert judgment. A total of 5 physicians from different specialties were counted. To calculate the degree of agreement between the expert judges, Aiken's V was used. As a decision criterion to keep an item, a value ≥ 0.7 was considered. Results: In relation to clarity, V values greater than 0.80 were presented, in addition to a variation coefficient of less than 25%, therefore, none of the items was eliminated. Regarding coherence, they presented a coefficient of variation above 20% and V values greater than 0.71, confirming the decision not to exclude any of them. Regarding the relevance of the items, V values higher than 0.90 were also evidenced and neither did any of them present a value below the critical one. Conclusions: The questionnaire has presented sufficient evidence of content validity in terms of clarity, coherence and relevance of the items through the aforementioned analyses. For this reason, it should be used to quantify the KAP of different population groups in the country.

Introduction: Noise-induced hearing loss has been implicated in the genesis of several chronic conditions; however, its behavior concerning hypertension still raises doubts about it. Objective: to determine the association between hearing loss due to exposure to noise and the presence of hypertension in a sample of Peruvian workers. Methods: Cross-sectional analytical study. Secondary analysis of the occupational database of a Medical center in Lima, Peru. hypertension was measured by self-report and clinical method. Hearing loss was classified as none, mild, moderate and severe. For the regression analysis, Poisson was performed with robust variance, obtaining crude (PRc) and adjusted (PRa) prevalence ratios. Results: We worked with a total of 1987 participants. The prevalence of hypertension was 15.40% and hearing loss was 36.39%. For the multivariate regression analysis, a statistically significant association with hypertension was found in those with mild hearing loss (PRa=1.52; CI95% 1.06–2.10), moderate (PRa=2.70; CI95% 1,93–3.76) and severe (PRa=3.82; 95% CI 2.56–5.96), compared to those without hearing loss. Conclusions: Hearing loss due to exposure to occupational noise was associated with the presence of hypertension. Although this study is only a first overview of the relationship that both variables could have, it is recommended to continue promoting policies and awareness campaigns to prevent hearing loss in workers, and thus avoid complications related to it in the long term.
