Social Outbreak in Chile, and Its Association with the Effects Biological, Psychological, Social, and Quality of Life.

The World Health Organization has defined collective violence as the instrumental use of violence by people who identify themselves as members of a group against other individuals and have political, economic, or social objectives. In Chile, the "Social Outbreak" was used to describe an episode of collective violence, which began on October 18, 2019, triggered by a multitude of socioeconomic and political factors, with protests and mobilizations in the country's large and small cities; in central, commercial, and residential areas, that lasted for several months, affecting a large part of the population. The objective of the present study was to associate the social outbreak in Chile with its biological, psychological, and social effects on people's health and quality of life, as well as its characteristics in terms of exposure, proximity, type, and frequency. This was a cross-sectional study with non-probabilistic national-level sampling, conducted from 28 November 2019, to 3 March 2020. The instrument had four sections. A total of 2651 participants answered the survey; 70.8% were female, and the mean age was 35.2. The main disturbances perceived were protests (70.9%), alarm sounds (68.1%), shooting sounds (59.0%), and tear gas bombs (56.9%). When quantifying the magnitude of these associations, people who had a medium exposure have a higher probability (OR: 1.99, CI: 1.58; 2.50) of suffering three or more biological effects than people that have a low exposure, while people with higher exposition have a 4.09 times higher probability (CI: 3.11; 5.38). A similar pattern was observed regarding psychological effects, although social effects were primarily experienced by those with high exposure. Social networks, TV, and radio were the most used media among people who perceived a greater effect. People who lived, worked, or shopped near the disturbance's areas show a higher proportion negative effect.

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. We conducted a pre-post intervention without control group, with a face-to-face structured multicomponent PE intervention (cardiovascular, strength/power, flexibility, static and dynamic balance, other psychomotor components, and education), based on FITT-VP principles (frequency, intensity, type, time, volume, and progression of exercise), at moderate intensity, 60 min per session, three times per week, and 12 weeks in duration, among 45 persons with an average age of 70.74 years. Participants were evaluated at the beginning and end of the intervention with different instruments of comprehensive gerontological assessment (CGA). Post intervention, participants (83.70% average attendance) significantly improved scores in QoL, biological and biopsychosocial frailty, sarcopenia, functionality in basic, instrumental, and advanced activities of daily living, dynamic balance, cognitive status and mood, systolic and diastolic blood pressure, weight, body mass index, strength and flexibility clinical tests of lower and upper extremity, aerobic capacity, agility, and tandem balance. The indication and prescription of structured multicomponent PE based on FITT-VP principles, as evaluated with the CGA, improved the QoL and biopsychosocial health of older adults. This intervention could serve as a pilot for RCTs or to improve PE programs or services for older adults under the auspices of existing public policy.

Social outbreak and its association with insomnia and daytime sleepiness in Chile.

Objectives: To associate the effects of the social outbreak with insomnia and daytime sleepiness according to the distance from the riots. Material and Methods: Cross-sectional analytical study; a non-probabilistic sampling was carried out at a national level. The Google Forms tool was used; a document was submitted using a national database. The instrument consisted of four sections: socio-demographic data, biopsychosocial symptoms, insomnia severity index (ISI), and the Epworth sleepiness scale (ESS). The data were analyzed using descriptive statistics and the zero-inflated negative binomial model. Results: Of a total of 2,532 surveyed people, 29% were male; 43% was younger than 30 years old. The 50% of the sample suffers from sleepiness and 71% shows some type of insomnia. The marginal effects of the zero-inflated negative binomial model show that women, people aged 51 or older, who are neither studying a healthcare degree nor working in the healthcare sector, that are exposed to 4 or more hours per day to the news and that live in areas near or very near the riots, have significantly higher ISI (marginal effect 1.356, SE 0.381, p-value 0.000) and ESS scores (marginal effect 0.693, SE 0.320, p-value 0.030). To live/work in rioting areas has the greater marginal effect compared to other determinants. Finally, neither employment status nor educational level are associated with significant effects in the aforementioned scales. Conclusion: The riots occurred during the social outbreak of October 2019 in Chile had an effect on insomnia and daytime sleepiness. Particularly, to live/work in rioting areas has the greater marginal effect compared to other determinants.

Efectos del ejercicio físico sobre la calidad de vida en personas mayores. Revisión de la literatura

RESUMEN El objetivo de esta revisión fue determinar cuál es la dosis óptima necesaria de ejercicio físico que debe realizar una persona mayor para generar efectos en la Calidad de Vida. Se realizó una búsqueda en bases de datos electrónicas entre 2015-2020. Como resultado, 9 de 33 artículos cumplieron con criterios de inclusión. La prescripción de ejercicio físico más utilizada en términos de FITT o FITT-VP fue: tipo, fuerza muscular a intensidad moderada a intensa, y/o ejercicio físico aeróbico a intensidad moderada; tiempo de sesión de 60 minutos; frecuencia 3 veces por semana; y tiempo de intervención mínimo 3 meses. En cuanto al volumen y progresión, la información fue limitada y justifica más estudios. Los efectos del ejercicio físico sobre la Calidad de Vida de las personas mayores se producirán cuando exista una programación basada como mínimo según FITT, se consideren los objetivos de la persona mayor, y la práctica sea regular.

ABSTRACT The objective of this review was to determine the optimal dose of physical exercise that an elderly person should perform to generate effects on Quality of Life. A search was carried out in electronic databases between 2015-2020. As a result, 9 of 33 articles met the inclusion criteria. The most used physical exercise prescription in terms of FITT or FITT-VP was: type, muscular strength at moderate to intense intensity, and / or aerobic physical exercise at moderate intensity; 60-minute session time; frequency 3 times a week; and intervention time at least 3 months. In terms of volume and progression, the information was limited and needs further studies. The effects of physical exercise on the Quality of Life of the elderly will occur when there is a schedule based at least according to FITT, the objectives of the elderly person are considered, and the practice is regular.

Relación entre Apoyo Social percibido, Severidad de Insomnio y Somnolencia Diurna en Adultos Mayores / Relationship between perceived Social Support, Severity of Insomnia and Daytime Sleepiness in Elderly

El apoyo social es un importante factor protector de la salud de los adultos mayores (AM). Asimismo, un buen dormir es fundamental para su bienestar y funcionalidad, siendo las alteraciones del sueño un importante problema de salud pública en este grupo etario. El objetivo del estudio fue determinar la relación entre apoyo social percibido, insomnio y somnolencia diurna en AM residentes en Chillán, Chile. Se realizó un estudio cuantitativo, no experimental, correlacional, de corte transversal. Se aplicó la versión chilena de la Escala de Apoyo Social Percibido (MOS), el Índice de severidad del insomnio (ISI), y la Escala de somnolencia diurna de Epworth a AM pertenecientes a agrupaciones comunitarias. Se entrevistaron a 202 AM de ambos sexos, de edad 72,3±6,2 años. Se presentaron correlaciones positivas entre escolaridad y severidad del insomnio (p<0,05) y entre severidad del insomnio y somnolencia (p<0,001), además, se encontraron correlaciones negativas entre severidad del insomnio y apoyo social percibido, tanto en forma global como por dimensiones (p<0,05). La dimensión "Interacción social positiva" se correlacionó también de forma negativa con la somnolencia diurna. Los AM participantes del estudio que presentaron un alto nivel de apoyo social presentaron una menor prevalencia y severidad del insomnio

Social support is an important protective factor for the health of elderly (E).Likewise, good sleep is fundamental for their well-being and functionality, being sleep disorder an important public health problem in this age group. The objective of this study was to determine the relationship between perceived social support, insomnia and daytime sleepiness in elderly residents of Chillán, Chile. A quantitative, non-experimental, correlational, cross-sectional study was carried out. The Chilean version of the Perceived Social Support Scale (MOS), the Index of severity of insomnia (ISI) and the Daytime Sleepiness Scale of Epworth was applied to elderly belonging to community groups. Two hundred two elderly of both sexes were interviewed, age 72.3 ± 6.2 years. There were positive correlations between schooling and severity of insomnia (p <0.05) and between severity of insomnia and somnolence (p< 0.001). In addition, there were negative correlations between severity of insomnia and perceived social support, both globally and by dimensions (p <0.05). The dimension "Positive social interaction" also correlates negatively with daytime sleepiness. The elderly participants of the study who presented a high level of social support had a lower prevalence and severity of insomnia

[Effects of physical exercise on sleep quality, insomnia, and daytime sleepiness in the elderly. A literature review]. / Efectos del ejercicio físico sobre la calidad del sueño, insomnio y somnolencia diurna en personas mayores. Revisión de la literatura.

The ageing process alters the stages of sleep, and the elderly that have this problem tend to be prescribed pharmacological treatment. This has long term side effects and results in increased health costs. On the other hand, frequent or regular physical exercise could be an overall superior alternative, due to its multifactorial effects. It is also less expensive, thus more affordable and accessible. Furthermore, these benefits could be extrapolated to the quality of sleep. Taking this into account the purpose of this paper is to establish the proper amount of physical exercise using the FITT (frequency, intensity, time, type of exercise) principle, and its effect on the quality of sleep, insomnia, and daytime sleepiness in the elderly. This could lead us to a paradigm shift in the treatment of sleep disorders, and also may constitute an alternative method for treating the elderly.

[Content validity of Food Quality Survey of Elderly (FQSE)]. / Validación de contenido de la Encuesta de Calidad de Alimentación del Adulto Mayor (ECAAM).

BACKGROUND: There are few instruments that evaluate the quality of food of elderly (ED) in the community. OBJECTIVE: To carry out the content validity of the survey designed to determine the Food Quality Survey of Elderly (FQSE). MATERIAL AND METHODS: Based on the existing literature, a questionnaire was designed to evaluate the FQSE. Content validity was performed using the Content Validity Index through the calculation of the Content Validity Ratio of Lawshe. Twenty-eight experts participated in the validation process. Subsequently, the validated survey was applied to ED. RESULTS: Twenty-three questions were validated in content, distributed in the 2 subscales of the instrument. The first 15 questions subscale Healthy eating habits and 8 questions subscale Unhealthy eating habits. The Content Validity Index was 0.85. Four hundred and fifty-eight ED were surveyed. In the subscale of Healthy eating habits, 11.2% of men and 11.4% of women presented healthy eating habits; 54.4% of men and 42.9% of women presented unhealthy eating habits. Finally, in the sum of both scales, only 16.6% of men and 17.6% of women categorize within Good Food Quality. CONCLUSION: The FQSE survey is a valid instrument in content and easy to apply to EL and allows evaluating and characterizing the quality of the diet of this age group.
