    Objective: To identify how Brazilian families with children aged under 13 years face the period of social isolation resulting from the COVID-19 pandemic, especially regarding the time spent on physical activity (PA), intellectual activity, games, outdoor activities and screen. Methods: An anonymous online survey was launched on March 24, 2020 in Brazil to assess how families with children aged up to 12 years are adjusting their daily routines to this situation. In the survey, each family reported the daily time each child spent in sedentary activity (sum of intellectual activities, play time on screen, playing without PA) and PA (sum of playing with PA and PA). Results: The main findings based on data from 816 children indicate that most parents consider there was a reduction in the time that children spend practicing PA; increase in screen play time and family activities, differences between sex were found regarding screen play time (boys>girls) and in playing without PA (girls>boys), and there was an age effect for all categories analyzed, with a tendency to increase the total time of sedentary lifestyle and complementary reducing the time of PA over age. Conclusions: The household routines of families during the period of social isolation resulting from the COVID-19 pandemic confirm the general reduction tendency in PA time during childhood.4811-99FE-2ECD | Luis Paulo RodriguesN/

    Problem Statement:The COVID-19 pandemic led to significant changes in the life routines of preschool children, both during lockdown and post-lockdown periods. Approach:An online survey completed by parents, in-loco assessment scales filled in by a researcherand semi-structured interviews with preschool teacherswere used to investigate the effects of the adjustments, which occurred in preschool children?s lives, in the lockdown and post lockdown periods.Purpose:To characterize the levels of physical activity that Portuguese children had during the lockdown period and to understand what changed in their school routines in the post-lockdown period, regarding the organization of school spaces and routines.Results:Parents reported that children aged 3 to 5spent most of their time during lockdownundertaking sedentary activities (72% of their daily activities). In the post-lockdown period,results indicate that in June there was an increase in the number of preschools with a poor quality of environment compared to the pre-pandemic period (October/November).Taking into account the measures implemented in preschools to prevent the COVID-19 transmission,teachers were of the opinion that limiting the number of children sharing material was the worst measure imposed, since it hampered children?s socialization. Conversely, increasing the use of the outdoor space was deemed positive because it improved children?s happiness and action possibilities outside.Conclusions: TheCOVID-19pandemic has had a clear impact on Portuguese children?s overall levels of physical activity during lockdown. In some schools, the implementation of health guidelines has also led to further negative effects on children?s play opportunities. However, many schools seem to be successful in finding strategies to ensure a healthy balance between promoting children?s physical activity and ensuring risk control.4811-99FE-2ECD | Luis Paulo Rodriguesinfo:eu-repo/semantics/publishedVersio

    Influences of family and household characteristics on children's level of physical activity during social distancing due to Covid-19 in Brazil

    Objective: To evaluate if the variables child?s sex, age, presence of siblings, parents working remotely, and external space affect the level of physical activity (PA) of Brazilian children during social distancing imposed by the COVID-19 pandemic. Methods: An online questionnaire was applied by the LimeSurvey software from March to April 2020. Children were divided into four age groups, and the questionnaire comprised questions on family and household characteristics, domestic and children?s routines in the period of Brazilian social distancing. Based on the answers concerning children?s activities, the following variable was created: percentage of physical activity (%PA) in one-day period. Analysis of variance and regression analysis were performed to investigate the effect of demographic and parental activities on %PA. Results: The %PA decreases with increasing age, but increases with the availability of external space at home. No significant or interaction effects were observed for other variables. Age and external space at home are predictors of %PA. Conclusions: Household and personal characteristics of Brazilian children influence the level of physical activity performed by them during social distancing. Preventive measures can be adopted in the face of another similar period.4811-99FE-2ECD | Luis Paulo RodriguesN/

    Factors behind job preferences of Peruvian medical, nursing and midwifery students: a qualitative study focused on rural deployment

    Get PDF
    Background: Deployment of health workforce in rural areas is critical to reach universal health coverage. Students? perceptions towards practice in rural areas likely influence their later choice of a rural post. We aimed at exploring perceptions of students from health professions about career choice, job expectations, motivations and potential incentives to work in a rural area. Methods: In-depth interviews and focus groups were conducted among medical, nursing and midwifery students from universities of two Peruvian cities (Ica and Ayacucho). Themes for assessment and analysis included career choice, job expectations, motivations and incentives, according to a background theory a priori built for the study purpose. Results: Preference for urban jobs was already established at this undergraduate level. Solidarity, better income expectations, professional and personal recognition, early life experience and family models influenced career choice. Students also expressed altruism, willingness to choose a rural job after graduation and potential responsiveness to incentives for practising in rural areas, which emerged more frequent from the discourse of nursing and midwifery students and from all students of rural origin. Medical students expressed expectations to work in large urban hospitals offering higher salaries. They showed higher personal, professional and family welfare expectations. Participants consistently favoured both financial and non-financial incentives. Conclusions: Nursing and midwifery students showed a higher disposition to work in rural areas than medical doctors, which was more evident in students of rural origin. Our results may be useful to improve targeting and selection of undergraduate students, to stimulate the inclination of students to choose a rural job upon graduation and to reorient school programmes towards the production of socially committed health professionals. Policymakers may also consider using our results when planning and implementing interventions to improve rural deployment of health professionals

    A Candidate for the Least-massive Black Hole in the First 1.1 Billion Years of the Universe

    We report a candidate of a low-luminosity active galactic nucleus (AGN) at z = 5 that was selected from the first near-infrared images of the JWST CEERS project. This source, named CEERS-AGN-z5-1 at absolute 1450 \uc5 magnitude M 1450 = −19.5 \ub1 0.3, was found via a visual selection of compact sources from a catalog of Lyman break galaxies at z > 4, taking advantage of the superb spatial resolution of the JWST/NIRCam images. The 20 photometric data available from CFHT, Hubble Space Telescope, Spitzer, and JWST suggest that the continuum shape of this source is reminiscent of that for an unobscured AGN, and there is a clear color excess in the filters where the redshifted Hβ+[O iii] and Hα are covered. The estimated line luminosity is L Hβ+[O III] = 1043.0 erg s−1 and L Hα = 1042.9 erg s−1 with the corresponding rest-frame equivalent width EWHβ+[O III] = 1100 \uc5 and EWHα = 1600 \uc5, respectively. Our spectral energy distribution fitting analysis favors the scenario that this object is either a strong broad-line emitter or even a super-Eddington accreting black hole (BH), although a possibility of an extremely young galaxy with moderate dust attenuation is not completely ruled out. The bolometric luminosity, L bol = 2.5 \ub1 0.3 7 1044 erg s−1, is consistent with those of z < 0.35 broad-line AGNs with M BH ∼ 106 M ⊙ accreting at the Eddington limit. This new AGN population in the first 1.1 billion years of the universe may close the gap between the observed BH mass range at high redshift and that of BH seeds. Spectroscopic confirmation is awaited to secure the redshift and its AGN nature
