    (Centro Interdisciplinario de Estudios en Bioética, Universidad de Chile, 2017) Merino, Catalina; Mattar, Gustavo; Leppe, Jaime; Bahamondes, Paz; Lecaros, Juan Alberto
    Background: Research in educational centers is a frequent source of social and health related studies. Objective: To determine the knowledge and adherence to the current legal and ethical regulations to research performed on children at educational institutions. Methodology: Cross-sectional study online survey-type. The level of knowledge and adherence to the ethical regulation and legislation in Chile, to conduct research with minors was consulted. Results: 126 educational institutions responded the survey; 69% belonged to urban centers; 60% corresponded to those under the Municipality umbrella and 34% to charter schools. Research was performed in 31,8% of the consulted institutions, 41% of the research was on health issues and 30,8% on education. The 27,5% answered that they had the approval of ethical-scientific committee, 82% answered that they neither received nor had any awareness of regulatory aspects on research. Conclusion: There is low knowledge and adherence to ethical and legal regulation to research performed with children in educational centers. A journey for dissemination of results was performed and a flow chart was created by experts and proposed to the school directors to contribute to the adherence of ethical and regulatory aspects of research in educational centers.

    (2018) Aguilar-Farias, Nicolas; Martino-Fuentealba, Pia; Cortinez-O’Ryan, Andrea; Chandia-Poblete, Damian; Celis-Morales, Carlos A.; Bahamondes, Paz; Leppe, Jaime; Brown, Wendy J.
    Background: Although evidence on the health effects of sedentary behavior (SB) has grown systematically in recent years, few developing countries have reported population levels of SB, especially in South America. Our objective was to describe time spent sitting in a representative sample from Chile categorized by age, gender, educational level, and body mass index (BMI). Methods: A national health survey was conducted in Chile in a nationally representative sample (n = 5411) in 2009-2010. Sitting time (ST) was measured with the Global Physical Activity Questionnaire Version 2. Results: Data were from 5031 participants (43.26± 0.41 years, mean± SE; 40.3% male). Overall, there were no gender differences in mean ST (men: 158.10± 5.80 min/day, women 143.45± 4.77 min/day; p = 0.05). ST was lower in those who lived in rural areas compared with urban areas (99.4 min/day vs. 160.0 min/day; p = 0.001). ST increased significantly with increasing BMI, but only in men (p = 0.009), and was positively related to years of education in both men and women (p<0.0001). Conclusion: The findings were different from those reported in other countries and contexts, reinforcing the need for international surveillance and monitoring over time to inform policy makers. Differences in ST across different groups emphasize the need to develop tailored messages and interventions for reducing ST in different population subgroups.
