Association between demographic, clinical characteristics and severe complications by SARS-CoV-2 infection in a community-based healthcare network in Chile.

Background: Most of the evidence on risk factors for COVID-19 complications comes from North America or Europe with very little research from Latin-America. We aimed to evaluate the association between sociodemographic, clinical factors and the risk of COVID-19 complications among adults in Chile, the fifth Latin-American country with more COVID-19 reported cases since de beginning of the Pandemic.

Methods: A retrospective population-based cohort study using data from electronic health records from a large Primary Care Network, linked to national hospital, immunization, Covid-19 PCR surveillance, mortality and birth records.

Multimorbidity and tooth loss: data from Chilean National Health Survey 2016-2017.

Background: Oral diseases are a significant global public health challenge. Current evidence indicates that several chronic conditions are individually associated with tooth loss. People are living with more than one chronic condition, known as multimorbidity (MM).

[Comorbidity of obesity and smoking and their association with cardiometabolic risk factors: Results from the 2016-2017 National Health Survey].

Background: The comorbidity between obesity and smoking and its association with cardiometabolic risk factors has been little explored.

Objectives: Describe the prevalence of such comorbidity and to explore its association with cardiometabolic risk factors.

Methods: The study was based on the 2016-2017 Chilean National Health Survey and included 6,233 participants.

National health examination surveys; a source of critical data.

The aim of this paper is to contribute technical arguments to the debate about the importance of health examination surveys and their continued use during the post-pandemic health financing crisis, and in the context of a technological innovation boom that offers new ways of collecting and analysing individual health data (e.g. artificial intelligence).

National Health Examination Surveys: an essential piece of the health planning puzzle.

National health examination surveys (HESs) have been developed to provide important information that cannot be obtained from other sources. A HES combines information obtained by asking participants questions with biophysical measurements taken by trained field staff. They are observational studies with the highest external validity and make specific contributions to both population (public health) and individual health.
