During the last years, muscle strengthening exercises have been included as an essential part in youth physical activity guidelines of national and international health organisations. It is well-documented that strength training is effective in improving physical fitness and promoting health and psycho-social well-being. Therefore, the purpose of this review article is to present empirical evidence on the effectiveness of strength training in children and adolescents. Additionally, and with reference to an established youth physical development model, conceptual and methodological aspects of safe and effective strength training in youth will be discussed and specific practical recommendations will be presented.

Background:Aerobic and muscle-strengthening activities are related to morbidities and mortality. Resistance exercise/strength training items are included in national surveys, but the manner in which muscle-strengthening activity is queried varies among these surveys.Purpose:The purpose of this study was to use different self-report measures to examine the prevalence of meeting the 2008 Physical Activity Guidelines for Americans regarding muscle-strengthening activities among women.Methods:We surveyed 606 community-dwelling women at 4 points in time across a 1.5- to 3-year time period to determine whether the respondents met the national physical activity guidelines for performing muscle-strengthening activities ≥ 2 days per week.Results:Results were consistent across time but depended on the manner in which the question was asked. If asked to reflect over the past month or a general question about the typical number of days engaged, approximately 40% of women reported engaging in ≥ 2 days per week of resistance exercise/strength training. However, when reports were obtained weekly for 13 weeks, only approximately 18% of respondents met the guidelines.Conclusion:Results indicate that the timing and nature of questioning can substantially influence the self-reported prevalence of muscle-strengthening physical activities for community-dwelling women.

As seen clearly from the coronavirus disease 2019 (COVID-19) pandemic, health is an important foreign policy and diplomatic issue connected with security, economic well-being, and international development. According to risk communication researchers, effective, transparent, and timely information sharing is the most important tool after vaccines for responding to pandemics. This study aims to start a scholarly discussion on the risk communication efforts of the World Health Organization (WHO) during the COVID-19 outbreak. We analyzed WHO’s communication efforts during the first 3 months of the COVID-19 pandemic. As the leading international health organization, WHO was responsible for providing rapid, up-to-date, and credible information for the public and the media. The selected research items were 42 news releases and statements provided by WHO between December 31, 2019, and March 30, 2020. These were subjected to qualitative and quantitative content analyses using the NVivo 12 qualitative analysis software program for coding. The data were coded under 6 variables (date of publication, topics, frequency, wording of the COVID-19 outbreak, sourcing, and themes of the releases). While 54.7% of WHO's communications were devoted to the COVID-19 outbreak, more than half were not issued until March. That is, instead of early risk communication and clear warnings about the outbreak, WHO acted overcautiously, preferring messages related to solidarity and cooperation during the most devastating pandemic of the 21st century.

Abstract Background Child maltreatment poses high risks to the mental health and cognitive functioning of children not only in childhood but also in later life. However, it remains unclear whether child maltreatment is directly associated with impaired cognitive functioning or whether this link is mediated by mental health problems. Our study aimed at examining this research question among children and adolescents in Uganda. Methods A sample of 232 school-going children and adolescents with a mean age of 14.03 (SD = 3.25) was assessed on multiple forms of maltreatment using the Maltreatment and Abuse Chronology Exposure—Pediatric Version (pediMACE). Executive functions were assessed by the Tower of London task and working memory by the Corsi Block Tapping task, while mental health problems were assessed using the Child PTSD Symptom Scale for PTSD and the Center for Epidemiological Studies Depression Scale for Children (CES-DC). Results In total, 232 (100%) of the participant reported to have experienced at least one type of maltreatment in their lifetime including emotional, physical, and sexual violence as well as neglect. We found a negative association between child maltreatment and executive functions (β = − 0.487, p < 0.001) and working memory (β = − 0.242, p = 0.001). Mental health problems did not mediate this relationship. Conclusions Child maltreatment seems to be related to lower working memory and executive functioning of affected children and adolescents even after controlling for potential cofounders. Our study indicates that child maltreatment the affects children’s cognitive functionality beyond health and well-being.

Purpose The purpose of this review article is to examine the well-being of faculty in higher education. Success in academia depends on productivity in research, teaching, and service to the university, and the workload model that excludes attention to the welfare of faculty members themselves contributes to stress and burnout. Importantly, student success and well-being is influenced largely by their faculty members, whose ability to inspire and lead depends on their own well-being. This review article underscores the importance of attending to the well-being of the people behind the productivity in higher education. Method This study is a narrative review of the literature about faculty well-being in higher education. The history of well-being in the workplace and academia, concepts of stress and well-being in higher education faculty, and evidence-based strategies to promote and cultivate faculty well-being were explored in the literature using electronic sources. Conclusions Faculty feel overburdened and pressured to work constantly to meet the demands of academia, and they strive for work–life balance. Faculty report stress and burnout related to excessively high expectations, financial pressures to obtain research funding, limited time to manage their workload, and a belief that individual progress is never sufficient. Faculty well-being is important for the individual and in support of scholarship and student outcomes. This article concludes with strategies to improve faculty well-being that incorporate an intentional focus on faculty members themselves, prioritize a community of well-being, and implement continuous high-quality professional learning.

Introduction: Transgender (TG) children and adolescents experience problems in school as well as with family and social relationships that can adversely affect their physical and psychosocial health and impair their quality of life (QOL). This study aims to assess health-related quality of life (HRQOL) in TG children. Methods: We performed a cross-sectional study comparing HRQoL in gender nonconforming (Trans) and gender conforming (CIS) children and adolescents using the Spanish version of KIDSCREEN-52 in 120 Chilean Trans and CIS children (aged 8–18 years) and their parents. All scores were standardized according to the KIDSCREEN manual. Results: Among the 100 questionnaires answered, 38 corresponded to children and adolescents aged 8.4–18 years. Twenty-one of them were TG (71% trans males) and 17 were CIS (76% females). Sixty-two parents answered the questionnaires: 33 from families of TG children (PTrans) and 29 from families of CIS children (PCis). Trans children had lower HRQOL scores in all domains compared to CIS children. The lowest-scoring domains for TG children were “Moods and Emotions”, “Psychological Well-Being” and “Social Acceptance”, and the highest-scoring domain was “School Environment”. The PTrans group had significantly higher scores than the Trans group for 3 of the 10 domains: “Psychological Well-Being”, “Moods and Emotions”, and “Parent Relations and Home Life”. Conclusion: Our results revealed that TG children and adolescents have lower QOL than their CIS counterparts, especially regarding items related to mental health. Furthermore, their parents may underestimate their well-being, confirming the vulnerability of the TG population. This finding underlies the need to perform early assessments of QOL for early detection and intervention in aspects that could deteriorate their quality of life.
