Nocturnal salivary cortisol and perceived stress in schoolteachers
Teaching is characterized by high exposure to occupational stressors that negatively impact the mental health of education professionals. In this context, the present cross-sectional study aimed to analyze the relationship between salivary cortisol levels and perceived stress in a sample of teachers. Subjective stress perception was assessed using the DASS-21 questionnaire, while salivary cortisol samples were collected by the participants themse…
Tobacco consumption and quality of life among teachers
Objective This study aimed to assess a bidirectional relationship between tobacco consumption and quality of life among Chilean teachers. Participants and methods A total sample of 647 Chilean teachers was included in a cross-sectional study (71.8% female). Teachers completed a socio-demographic questionnaire, tobacco consumption habits, and the SF-36 questionnaire to assess quality of life. Logistic regression models were employed for statistica…
Depression, Anxiety, and Stress among Teachers during the Second Covid-19 Wave
There is a strong background indicating that the teaching profession is one of the most stressful and that their mental health has deteriorated even further during the pandemic. However, there is a little background about the impact of the COVID-19 infection peaks and teachers’ mental health. To this end, 313 teachers were recruited. Via online questionnaires, an evaluation was performed on their depression, anxiety, and stress symptoms on the DA…
Musculoskeletal Disorders Associated With Quality of Life and Body Composition in Urban and Rural Public School Teachers
Introduction: Teachers have been reported to be a labor group with high rates of musculoskeletal disorders (MSDs), stress, and strong deterioration of quality of life (QoL). However, little information exists about the association between MSD, QoL, and body composition in rural and urban teachers. Objective: The aim was to study the association of MSD with QoL perception and body composition of urban and rural teachers. Participants and Methods: …
Impact of the Covid-19 Pandemic on Teacher Quality of Life
Prior to the COVID-19 pandemic, teachers were already reporting a low quality of life (QoL) perception, with a significant impact on mental and physical health due to various stress factors associated with work overload. The objective of this study was to evaluate the QoL impact on Chilean teachers before and during the COVID-19 pandemic. The analysis was performed following a longitudinal design on a sample of 63 Chilean teachers in pre-pandemic…
Association Between Body Composition, Somatotype and Socioeconomic Status in Chilean Children and Adolescents at Different School Levels
This study examined the association between body composition, somatotype and socioeconomic status (SES) in Chilean children and adolescents by sex and school level (grade). The cross-sectional study was conducted on 1168 schoolchildren aged 6–18 years (572 males) from Valparaíso, Chile. Body composition, as assessed by percentage body fat (BF%) and somatotype, was evaluated using Ellis equations and the Heath–Carter method, respectively. The soci…
Gender differences in predictors of self-rated health among older adults in Brazil and Chile
We conclude that when examining gender differences in predictors of SRH, the similarities are greater than the differences between Brazilian and Chilean older adults. In both countries, physical health was the most important predictor of SRH. In addition, absence of depression was the strongest predictor of good health in older Brazilian adults
P1-70 Prevalence of dependency in older people in chile. Frequency and social differentials
Introduction The process of population ageing in developing countries has important economic and social consequences. Dependency in the elderly constitutes a main concern for them considering the associated need of care, institutionalisation and health costs. Aim To assess the prevalence of dependency in older people in Chile. Methods Cross-sectional study in a national representative sample of 4546 people 60 y and older (61.5% women) living in t…
SP3-86 Validation of a single question for quality of life assessment in Chilean older people
Aim To validate a single question of self-reported quality of life as a reliable instrument in population studies. Method Cross sectional validation of a single question about QoL against the quality of life SF-36 (Short-Form 36 Health Survey). The study was performed in a national representative sample of 4762 community-dwelling people 61–101 y (38.8% men) from a national study on dependency done in Chile in 2009–2010. All subjects completed hou…
P1-156 Falls risks factors at home in chilean older people living in the community
Introduction Older adult (OA) falls are a major public health problem being a main cause of disability and morbidity (30% of prevalence around the world), involving an extensive use of health services, and higher costs. Latin American data (2000) show higher prevalence of multiple falls among Chilean (20.3%) and Mexican (19.5%) elders than in the Region (10%–15%). In Chile (2006), major part of the accident among elderly occurs at home (56%). The…
Geochemical Analysis of Vitreous Rocks Exploited During the Formative Period in the Atacama Region, Northern Chile
Petrographic analysis and geochemical characterization studies were carried out on vitreous dacite and/or rhyodacite artefacts from Formative period archaeological sites in the upper Salado River Basin in the Atacama Desert, northern Chile. These were compared with samples taken from two source areas located within the subregion, named Linzor and Paniri. Source samples and archaeological specimens were analysed by inductively coupled plasma – mas…
Predictive equations for stature in the elderly
Sex-specific stature prediction equations based on knee-height and age were obtained from large representative samples from selected cities of Latin America
