Presentation: This article presents our critical appraisal of an observational study published in the International Journal of Environmental Research and Public Health in 2022. Conclusions of the Study: An inverse association was identified between living at higher altitudes and the level of cardiometabolic risk in the Peruvian adult population. However, the prevalence of cardiometabolic risk in the different altitude categories evaluated remains above 82% (80.9 - 84.6), which represents a large proportion of the population at risk at every altitude. Critical comment: The study is relevant because of the use of the waist-height ratio, considered an anthropometric indicator with greater precision for estimating cardiometabolic risk, being a study with a low risk of bias, and having national representativity. In addition, it is important because the waist-height ratio is inexpensive and ea...

Objetive. The cohort study is an observational design. This only includes participants who have the same risk of being exposed, then compares who is exposed and unexposed presents the outcome of interest during the same period. The temporality between the exposure and the outcome of interest in a cohort study is well defined because it is certain that the exposure antecedent to the outcome of interest. Cohort studies can be prospective, retrospective, or a combination of both. One of the main advantages is its longitudinal nature, making it possible to estimate the incidence and relative risk as an association of interest. Some variables may vary over time, so it is essential to use advanced data modeling techniques such as fixed and random effects models.

Introducción: Es importante medir en la población la percepción del impacto que han tenido las medidas adoptadas por los gobiernos ante la rápida expansión del coronavirus. Objetivo: Determinar la percepción de las medidas implementadas por el gobierno de Perú en materia de salud pública para frenar el avance de la COVID-19. Métodos: Estudio transversal, analítico y multicéntrico, para el cual se hizo una encuesta virtual en la que participaron más de 4000 personas de todo el país. Resultados: La gran mayoría estaban a favor que esta es una epidemia/pandemia grave (47 % de acuerdo y 42 % muy de acuerdo), sin embargo, solo el 22 %, 21 %, 17 % y 46 % que el país, el sector salud, los hospitales y los médicos, respectivamente, están preparados para enfrentarla. Las medidas más apoyadas en cuanto a migración fueron la aprobación del cierre de fronteras (68 % muy de acuerd...
