RESUMO
Risk perception is considered the primary motivator for taking preparedness actions. But people with prior experience and a high-risk perception are not necessarily more prepared. This relationship is even more complex when assessing preparedness levels for hazards with different characteristics. These inconsistent findings can be explained by how preparedness has been measured and the influence of other factors, such as trust and risk awareness. Thus, the main goal of this study was to analyze the role of risk awareness and trust in authorities on risk perception and intention to prepare for natural hazards in a coastal city in Chile. A representative sample of the city of Concepción, located in the center-south zone of Chile (n = 585), completed a survey. We measured risk awareness, risk perception, trust in authorities, and intention to prepare for two hazards: earthquakes/tsunamis and floods. Through structural equation models, we tested five hypotheses. We found that the perception of risk maintained a direct and positive influence on the intention to prepare for both hazards. The results showed that awareness and risk perception influence the intention to prepare and should be considered different concepts. Finally, trust did not significantly influence risk perception when faced with known hazards for the population. Implications for understanding the relationship between risk perception and direct experience are discussed.

Risk perception has been largely examined in studies that have aimed to explain and predict preparedness behavior in the context of natural hazards. Findings from studies on the relationship between previous experience, preparedness, and risk perception in disaster situations have been inconsistent. Hence, the main goal of this work was to explore the influence of physical and emotional experience on risk perception regarding natural hazards. This study was conducted in a statistically representative sample of the city of Iquique, in northern Chile (n = 701), who completed a survey one month after the occurrence of an earthquake and tsunami (8.2 Mw). The survey assessed the experience and preparation actions of survivors in relation to this event. Using a structural equation model, we examined nine proposed relationships, six of which were significant. The final model had an adequate fit (χ² = 752.23, df = 283, comparative fit index [CFI] = 0.90, root mean square error of approximation [RMSEA] = 0.049). Direct experience showed the greatest influence on risk perception: while direct physical experience (i.e., the physical and material consequences associated with the earthquake) maintained a direct positive effect on risk perception, direct emotional experience (i.e., the fear of experiencing an earthquake) produced an indirect positive effect (through worry). Emotional experience, however, did not directly influence current preparedness and risk perception. Implications for understanding the relationship between risk perception and direct experience are discussed.

The growing multi-hazard environment to which millions of people in the world are exposed highlights the importance of making sure that populations are increasingly better prepared. The objective of this study was to report the levels of preparedness of a community exposed to two natural hazards and identify the primary sociodemographic characteristics of groups with different preparedness levels. A survey was conducted on 476 participants from two localities of the Atacama Region in the north of Chile during the spring of 2015. Their level of preparedness at home and work was assessed to face two types of natural hazards: earthquakes and floods.The findings show that participants are significantly better prepared to face earthquakes than floods, which sends a serious warning to local authorities, given that floods have caused the greatest human and material losses in the region's recent history of natural disasters. Men claimed to be more prepared than women to face floods, something that the authors attribute to the particular characteristics of the main employment sectors for men and women in the region. The potential contribution of large companies on preparedness levels of communities in the areas in which they operate is discussed. The sociodemographic profile of individuals with the highest levels of preparedness in an environment with multiple natural hazards are people between 30 and 59 years of age, living with their partner and school-age children. The implications of the results pertaining to institutions responsible for developing disaster risk reduction plans, policies and programs in a multi-hazard environment are discussed.

Researchers have previously reported that hazard proximity can influence risk perception among individuals exposed to potential hazards. Understanding this relationship among coastline communities at risk of flood events caused by storms and/or tsunamis, is important because hazard proximity, should be recognized when planning and implementing preparation and mitigation actions against these events. Yet, we are not aware of studies that have examined this relationship among coastline inhabitants facing the risk of a tsunami. Consequently, the aim of this study was to examine the relationship between hazard proximity and perceived risk from tsunamis among coastline inhabitants. Participants were 487 residents of the coastal city of Iquique, Chile. They completed a survey during the spring of 2013 that assessed their perceived risk from several natural and non-natural hazards. We found that hazard proximity maintains a negative relationship with the perception of tsunami risk among coastline inhabitants. While this result confirms the general trend obtained in previous studies, this one is conclusive and significant. In contradiction with previous findings, we found that participants from the highest socioeconomic status reported the highest levels of risk perception. This finding can be explained by the fact that most participants from the highest socioeconomic status live closer to the coastline areas, so their risk perception reflects the place where they live, that is in a tsunami inundation zone. Once again, hazard proximity proved to be a determinant factor of risk perception. Our findings have important implications for the development of plans and programs for tsunami preparedness and mitigation. These indicate that individuals do use environmental cues to evaluate their own risk and can potentially make correct choices when having or not to evacuate. Also suggest that preparedness should incorporate how hazard proximity is recognized by individuals and communities at risk.

BACKGROUND: In addition to smoking, acute exacerbations are considered to be a contributing factor to progression of chronic obstructive pulmonary disease (COPD). However, these findings come from studies including active smokers, while results in ex-smokers are scarce and contradictory. The purpose of this study was to evaluate if frequent acute moderate exacerbations are associated with an accelerated decline in forced expiratory volume in one second (FEV1) and impairment of functional and clinical outcomes in ex-smoking COPD patients. METHODS: A cohort of 100 ex-smoking patients recruited for a 2-year follow-up study was evaluated at inclusion and at 6-monthly scheduled visits while in a stable condition. Evaluation included anthropometry, spirometry, inspiratory capacity, peripheral capillary oxygen saturation, severity of dyspnea, a 6-minute walking test, BODE (Body mass index, airflow Obstruction, Dyspnea, Exercise performance) index, and quality of life (St George's Respiratory Questionnaire and Chronic Respiratory Disease Questionnaire). Severity of exacerbation was graded as moderate or severe according to health care utilization. Patients were classified as infrequent exacerbators if they had no or one acute exacerbation/year and frequent exacerbators if they had two or more acute exacerbations/year. Random effects modeling, within hierarchical linear modeling, was used for analysis. RESULTS: During follow-up, 419 (96% moderate) acute exacerbations were registered. At baseline, frequent exacerbators had more severe disease than infrequent exacerbators according to their FEV1 and BODE index, and also showed greater impairment in inspiratory capacity, forced vital capacity, peripheral capillary oxygen saturation, 6-minute walking test, and quality of life. However, no significant difference in FEV1 decline over time was found between the two groups (54.7±13 mL/year versus 85.4±15.9 mL/year in frequent exacerbators and infrequent exacerbators, respectively). This was also the case for all other measurements. CONCLUSION: Our results suggest that frequent moderate exacerbations do not contribute to accelerated clinical and functional decline in COPD patients who are ex-smokers.

BACKGROUND: Traffic accidents are the second leading cause of death among adolescents and young adults in Chile. However, few studies have examined this behavior among this age group. Parental practices have a great influence on risk behaviors in adolescents, such as substance use, sexuality and violence, among others. Specifically, we propose that these practices will influence pedestrian risk behaviors among adolescents. AIM: To study the role of parental practices such as mother and father support, and behavioral control (monitoring and presence of rules) in pedestrian risk behaviors of teenagers. MATERIAL AND METHODS: A sample of 470 adolescents attending schools in the Metropolitan Region of Santiago, Chile were studied. They answered a self-administered questionnaire in which they were asked about parental practices and pedestrian risk behaviors. Analyses were performed using descriptive and inferential statistics, using multiple regression. RESULTS: Paternal support and the presence of rules were protective factors for pedestrian risky behaviors. However, maternal support or monitoring did not influence these behaviors. CONCLUSIONS: Parental practices influence pedestrian behaviors of teenagers. The study provides further evidence for the importance of these practices in the development of behavioral self-regulation.

En diversos estudios los investigadores han encontrado una relación entre insatisfacción corporal, creencias de control de peso asociadas al consumo de cigarrillos y el consumo de cigarrillos en jóvenes. Este estudio evaluó un modelo de mediación de las creencias de control de peso asociadas al consumo de cigarrillos en la relación entre insatisfacción corporal y consumo de cigarrillos. Se realizó un estudio correlacional con 651 jóvenes chilenos de entre 12 y 23 años de edad. Se realizaron ANOVA y análisis de regresión lineal para evaluar las hipótesis propuestas. Se encontró una relación entre insatisfacción corporal y consumo de cigarrillos y diferencias significativas en dicha relación según sexo. Los resultados obtenidos confirman la relación entre insatisfacción corporal y consumo de cigarrillos en jóvenes chilenos, sin embargo, no se comprueba la mediación propuesta.
In several studies, researchers have found a link between body dissatisfaction, weight control beliefs associated with cigarette use and cigarette smoking among young people. This study examined a mediation model of weight control beliefs associated with cigarette use for the relationship between body dissatisfaction and cigarette smoking. A correlational study was conducted with 651 young chileans between 12 and 23 years of age. ANOVA and linear regression analyses were conducted to evaluate the proposed hypotheses. A relationship between body dissatisfaction and smoking and significant differences by sex for this relationship were found. These results confirm the relationship between body dissatisfaction and cigarette smoking among young Chileans, however, do not support the proposed mediation.
