[Potential biases in epidemiological studies using respondent-driven sampling method: a comparison between its face-to-face and online application.].

In epidemiological and social studies on populations without a sampling frame or that are hard to reach, respondent-driven sampling (RDS), under certain assumptions, has the potential to produce asymptotically unbiased and efficient population estimates for these populations. While RDS is typically conducted face-to-face, the online version (WebRDS) has gained attention due to its potential advantages, although its disadvantages have also raised concern. The objective of this study was to contrast these two formats at the level of application and potential biases, where the online version offers improved speed and lower costs but raises concerns about potential biases due to a lack of face-to-face instructions regarding definition of the social network size and peer-recruiting process.

Effects of sociodemographic and health factors on the self-management of non-communicable diseases among Chilean adults during the Covid-19 pandemic.

Individuals with non-communicable diseases (NCDs) are potentially at increased vulnerability during the Covid-19 pandemic and require additional help to reduce risk. Self-management is one effective strategy and this study investigated the effect of sociodemographic and health factors on the self-management of some non-communicable diseases, namely hypertension, type 2 diabetes mellitus and dyslipidemia, among Chilean adults during the Covid-19 pandemic. A cross-sectional telephone survey was carried out on 910 participants with NCDs, from Santiago, Chile.

Effects of a Structured Multicomponent Physical Exercise Intervention on Quality of Life and Biopsychosocial Health among Chilean Older Adults from the Community with Controlled Multimorbidity: A Pre-Post Design.

Structured multicomponent physical exercise (PE) for older adults, with a combination of strength, aerobic, flexibility, and balance exercises, has been shown to have benefits for physical, cognitive, social, and metabolic functioning, as well as counteracting chronic pathologies and geriatric syndromes. However, little is known about the effect of these interventions in Chilean older adults. Our objective was to determine the effect of a structured multicomponent PE intervention on the quality of life (QoL) and biopsychosocial factors of community-living older adults.

Translation and cross-cultural adaptation of the "Quality of Life in Epilepsy (QOLIE-31-P)" Questionnaire for Chile.

Purpose: To report the translation and cross-cultural adaptation of the Quality of Life in Epilepsy (QOLIE-31-P) Questionnaire in patients with epilepsy (PWE) in Chile.

Methods: Translation from the original and posterior back-translation was performed by independent translators, two in each step. The final consensual translation was modified for the Chilean context and assessed by cognitive interviews with 12 PWE from Chile's public healthcare system, selected by quotas.

Identification of daily environmental noise patterns in two different urban sites in Santiago, Chile.

Background: Environmental noise can cause auditory and non-auditory adverse effects.

Aim: To identify daily environmental noise patterns in two urban sites of Metropolitan Santiago.

Material And Methods: Continuous measurements of environmental noise in two sites of Metropolitan Santiago were analyzed by means of hierarchical cluster analysis.

Prevalence and Risk Factors for HIV Infection in a Population of Homosexual, Bisexual, and Other Men Who Have Sex with Men in the Metropolitan Region of Chile: A Re-emerging Health Problem.

According to the most recent UNAIDS report, the number of new HIV infections has increased by 34% since 2010 in Chile, representing the largest increase in the Americas. The objective of this study was to identify factors associated with HIV prevalence among men who have sex with men (MSM) in the metropolitan region (MR) of Santiago, Chile. Cross-sectional study of MSM living in the MR, recruited using respondent-driven sampling (RDS).

Trace element contents in fine particulate matter (PM) in urban school microenvironments near a contaminated beach with mine tailings, Chañaral, Chile.

Air quality in schools is an important public health issue because children spend a considerable part of their daily life in classrooms. Particulate size and chemical composition has been associated with negative health effects. We studied levels of trace element concentrations in fine particulate matter (PM) in indoor versus outdoor school settings from six schools in Chañaral, a coastal city with a beach severely polluted with mine tailings.
